The positive effect of orally administered collagen peptides on skin health has been demonstrated in several clinical trials. In this placebo-controlled study, the impact of specific fish-derived Bioactive Collagen Peptides (BCP) on skin elasticity and wrinkle reduction was investigated.
A total of 76 Asian and Caucasian women (62.2 ± 8.2 years of age) received a daily dosage of 5 g BCP or placebo. Skin elasticity and changes in eye wrinkle volume were evaluated at the beginning of the study, after 4 and 8 weeks of treatment and 4 weeks after the last intake (regression phase). In a subgroup analysis, differences between the results for Asian and Caucasian participants were investigated. The data showed a statistically significant (p<0.05) improvement in skin elasticity after only 4 weeks of BCP supplementation, compared with placebo. This positive effect persisted after 8 weeks of supplementation, and 4 weeks after BCP intake was stopped (p<0.05). Wrinkle volume was also reduced in a statistically significantly (p<0.05) manner after BCP treatment, compared to placebo. A pronounced decrease in eye wrinkle volume could be determined 4 weeks after BCP treatment commenced. After 8 weeks, a wrinkle reduction of 15% was observed and the efficacy of the treatment was confirmed at the end of the regression phase (p<0.05). The subgroup analysis revealed no statistically significant differences. The BCP treatment was effective in both Asian and Caucasian subjects. The results clearly demonstrated the efficacy of orally administered fish-derived BCP on skin health.28 Novembre 2019

The gastrointestinal (GI) microbiota plays a key role in health and disease.
It also has a longdistance effect influencing the brain through the gut–brain
axis. The establishment of an effective GI microbiota is associated with
human milk oligosaccharides (HMOs). In animal studies there is evidence that
HMOs can influence brain activity and cognitive development. This further
suggests that management of the GI microbiota by dietary means could
impact upon a wide range of diseases. Autism, which is the familiar name
for autism spectrum disorder (ASD), comprises a group of heterogeneous
neurodevelopmental disorders characterized by social deficits, repetitive
and stereotypical behaviours, insistence on routines and communication
impairments. GI abnormalities are a characteristic of a substantial number
of children with ASD. These children possess a lower overall abundance of
beneficial taxa, such as Bifidobacteria and Akkermansia, in the GI microbiota.
Many children with ASD have higher counts of potentially pathogenic
Clostridia than normally developing children.
The underlying pathophysiology of ASD remains unknown although
sub-optimal breast-feeding practices are associated with ASD. HMOs
selectively promote the growth of Bifidobacteria in the GI tract, which is
associated with numerous beneficial health outcomes.
There are two potential benefits of HMOs in alleviating autism.
Firstly, supplying HMOs to infants though breast-feeding can help establish
a functional GI microbiota and thus avoid GI dysbiosis which is commonly
related to the onset of autism. Secondly, administration of HMOs may
alleviate the symptoms of autism through an effect on the gut–brain axis.15 Ottobre 2019

Monascus purpureus (MTCC 1090) was obtained from the IMTECH Culture Collection Centre, Chandigarh, India. Extracellular and intracellular polyketide pigment was produced by solidstate fermentation using red rice production and pigments were extracted with methanol solvent. Maximum pigment production was found with intracellular extraction and the total yield of pigment was 41 U/g followed by 33 U/g for extracellular production by substrate fermentation. Crude pigments were separated by column chromatography and an antibacterial study revealed that the yellow pigment was most effective against all test pathogens and the red pigment was found to be a potent antioxidant. The greatest antagonistic activity was almost 91% against Trichophyton rubrum followed by 88% against Microsporum canis.26 Settembre 2019

Teething discomfort is a widespread disorder affecting a very high
percentage of infants. It creates anxiety in parents, who look for help in
paediatric clinics. The use of hyaluronic acid gels has been shown in the
last 20 years to be an effective tool, generally devoid of side effects, in
reducing oral mucosal inflammation in adults.
Recently, such results have also been confirmed in infants affected by
teething. From our routine practice results, we have retrospectively
reported the efficacy and the safety profile of Bonjela® Soothing Teething
Gel, a teething gel capable of addressing in a significant way this infant
complaint, which improves all of the clinical outcomes used in these types
of study to describe the clinical condition of infants.20 Settembre 2019

Oral mucosal ulcers are quite common in an otherwise healthy population,
and can determine a real worsening of the quality of life.
Conventional therapy is not appropriate since ulcers often recur and, even
if not needed, therapy lasting not less than 2–3 weeks carries a high risk
of serious side effects. The use of hyaluronic acid applied as an adhesive
gel over the lesions seems to have potential in terms of efficacy and the
avoidance of side effects. Of course, hyaluronic acid-based formulations
show different effects and tolerability.
In our study, we retrospectively report the results obtained using a medical
device, Bloxaphte®, applied for 14 days to counteract ulcers in adults.
Our data clearly demonstrate the healing capability and safety profile of
the product in reducing the number and size of the ulcers within the first
week of daily application.16 Settembre 2019

Furanoeudesma-1,3-diene, curzerene and lindestrene are thought to be the active principles underlying the analgesic action of myrrh (Commiphora molmol) extract. Recently, a very highly standardized dry extract from myrrh has been developed (RodeMyr®) and formulated in a single active nutritional supplement (Mirra+®), notified to the Italian Health Authorities in 2018. We have therefore used such a finished product to evaluate the analgesic action of myrrh in subjects affected by chronic pain. The results of the study have shown that the use of 100 mg of dry myrrh extract, administered twice a day, is effective in reducing pain perception and functio laesa both as a sole and an add-on therapy. Tolerability, compliance and side effect evaluation demonstrated the safety profile of the extract and its usefulness in treating patients with chronic pain.16 Settembre 2019

In an attempt to better characterize the strain M247, a strain of Lactobacillus crispatus isolated in 1989 from the faeces of a healthy newborn baby, we have further investigated its antibiotic resistance profile, evaluating also antibiotics not recommended by the EFSA, and analyzing in addition its viability in the presence of a high concentration of boric acid, a molecule commonly use to eradicate antimycotic-resistant fungi from the vagina. At the same time, we have evaluated the ability of M247 to adhere to vaginal epithelial cells to get a better understanding of its vaginal colonizing properties. According to the obtained results, M247 appears to be insensitive to metronidazole, sulfamethoxazole and boric acid. Such resistance is not transferrable due to the total absence of mobile elements inside its genome. Moreover, the M247 strain has been shown to adhere by more than 70% to vaginal epithelial cells, thereby providing a mechanistic explanation of its vaginal colonizing capabilities observed both after local and oral use.28 Agosto 2019

The oral administration of Streptococcus salivarius K12 represents a valid solution for the prevention of pharyngitis or pharyngotonsillitis, of bacterial or viral origin, and/or acute otitis media. In particular, this could be an interesting alternative to antibiotic prophylaxis in patients with relapse or disease recurrence. In this regard, the studies published in the scientific literature are limited, and thus, it was of interest to provide a meta-analysis in order to analyze in more detail the results obtained in this research field. For the meta-analysis, clinical studies were selected, as identified through PubMed, which examined the relationship between the use of formulations based on Streptococcus salivarius K12 and the number of cases or episodes of pharyngitis or pharyngotonsillitis, of bacterial or viral origin, and acute otitis media in children and adults. The effect size (ES) was calculated according to Cohen using the fixed effects model (fixed effects). Seven studies met the predefined inclusion criteria and they were included in the meta-analysis. ES values equal to -1.40 [-1.67; -1.13] and -1.01 [-1.19; -0.83] were obtained for the effect of Streptococcus salivarius K12 on the prevention of pharyngitis and acute otitis media, respectively. Both values were translated into a "big effect" according to Cohen's scale. Treatment based on this strain is effective for both the prevention of pharyngitis and acute otitis media. In addition, it is further revealed that the strain is more effective in the prevention of pharyngitis. It is desirable that further clinical investigation continues to expand and update the meta-analysis work and to recommend the use of the strain as a useful prophylactic tool to reduce the events of pharyngotonsillitis and acute otitis media.24 Giugno 2019

Jackfruit belongs to the family Moraceae and is used as a novel source of
starch. In the native stage, starch granules are generally insoluble at room
temperature, extremely resistant to enzymatic hydrolysis and display an
inability to endure processing conditions related to pH, temperature,
shear rate and freeze–thawing.
Modification can be carried out using chemical, physical or enzymatic
methods, or a combination of these. To solve this problem, modification
of starches is usually conducted to alter pasting, gelatinization and
retrogradation behavior.
Modified starches have been recognized as a multifunctional
excipient in various industries.
This review covers a wide array of topics relating to starch, including:
methods of modification; the impact of modification on morphology,
crystallinity, viscosity and functionality; and the application of modified starch.21 Giugno 2019

This study evaluated the oral administration of a new supplement
containing a combination of bioactive agents (hyaluronic acid, glucosamine
sulfate, chondroitin sulfate, alpha-lipoic acid, methylsulfonylmethane
and vitamins A, C and E).
The objective of the study was to demonstrate that the oral administration
of this product combats vulvovaginal atrophy in young women.
This observational study recruited 32 women of fertile age with vaginal
dryness, post-coital cystitis and/or dyspareunia (painful intercourse).
Patients were evaluated using the VHI scale and the FSFI at baseline and
at each follow-up. All patients took one tablet of the supplement twice
daily (morning and evening) for two months.
After two months, 28 patients (87%) showed an improvement in symptoms
and reported complete remission.
At the first follow-up at three months, that is, one month after stopping
treatment, no substantial changes were reported. At the second follow-up
at four months, that is, two months after stopping treatment, vaginal dryness
had recurred, and patients were asked to re-start the therapy.
We can conclude that this product is highly effective in young women suffering
from vaginal dryness and sexual dysfunction caused by oxidative
stress.17 Giugno 2019

The development of contemporary knowledge in the field of oral microbiology and probiotics was commenced by Elie Metchnikoff's report on Lactobacillus bulgaricus in 1907. Since then, multiple indications for the use of probiotics have been established, following the WHO definition: "probiotics are live microorganisms, which when applied in adequate amount may benefit the host health status". In accordance with a general classification, several types of bacteria and fungi have been distinguished and, moreover, their mechanisms of action run parallel in both the gut and oral cavity. The possible use of probiotics in dentistry is a relatively new idea. Until now, three species prevailed in available research: Bifidobacterium, Lactobacillus rhamnosus GG and Lactobacillus reuteri. Current research focuses on the application of probiotics and the natural displacement of cariogenic bacteria within the oral cavity, and the subsequent alteration of health status in both adults and children. Carioblis BLIS M18 probiotic, which contains freeze-dried cultures of Streptococcus salivarius M18, was introduced to the market as a supplement indicated for patients with a high caries rate. The aim of this study was to investigate the influence of the BLIS M18 strain on oral cavity microflora and estimate possible health outcomes.28 Maggio 2019

Food neophobia means not accepting a new food, which seems to be a
protective mechanism against new foods. The aim of this study was to
assess the food neophobia status in Ardabil children.
The present study was a cross-sectional study to assess the situation
of children's disgust at two to six years of age in households in Ardabil.
A questionnaire relating to five main food groups was used to assess the
type of food that was hated. A questionnaire containing four questions
was completed to check the factors affecting food neophobia.
The results of the study showed that 52.5% (95% confidence interval)
of the children were suffering from food neophobia. The children in
the study felt more disgusted about dairy products and vegetables.
Parents have stated that their children refuse to eat fruit and vegetables.
More than half of the children were suffering from food neophobia
and the socioeconomic status of parents, parental employment and the
type of child feeding before the age of two were among the factors influencing
the disgust of children in the study.24 Maggio 2019

Among the most important risk factors for cardiometabolic disease, hypertension, hypercholesterolaemia and diabetes mellitus play a main role; these chronic diseases are involved in creating huge health expenditure, with respect to both clinical–instrumental analysis and from a pharmacological point of view. An earlier stage of these diseases is the pre-risk (Fig. 1), a condition that, if not properly recognized and treated, can progress to the documented risk. We will talk about pre-hypertension, hypercholesterolaemia in primary prevention and dysglycaemia.21 Maggio 2019

Menaquinone-7 (MK-7) is a type of vitamin K of fermentative origin that plays a key role in cardiovascular and bone health as a cofactor of gamma-glutamyl carboxylase enabling the activation of several vitamin K-dependent proteins, particularly at the extrahepatic level. Despite its proven biological efficacy and outstanding bioavailability over other dietary menaquinones, its presence in food is marginal, especially in the Western diet. Dairy products are a major dietary source of menaquinones of minor biological relevance for human health and constitute optimal carriers due to their lipid content. Dairy fortification with MK-7 represents an attractive formulative strategy, also for the high calcium and vitamin D content that may act synergistically in promoting vitamin K-dependent functions. However, limited solubility of MK-7 in aqueous solution may limit its use and affect its bioavailability in vivo. The present study compares the bioavailability of MK-7 in enriched 1%-fat milk either as a direct powder solution or a pre-emulsified dispersion. Bioavailability data show that formulation strategies strongly affect the bioavailability of MK-7 and that the results are greatly improved when it is prepared as an oil–water emulsion.16 Maggio 2019

Nutritional status assessment of the individual is a key aspect in the monitoring of health status. In this context, body composition evaluation results are of fundamental importance. Several body composition techniques can be used depending on the information needed and the examined categories, and all the techniques are characterized by advantages and disadvantages. In this regard, this study aims to evaluate and compare the most commonly used techniques to evaluate body fat mass percentages in different situations.
Fifty subjects took part in the study. Anthropometric data were collected and the percentage of fat mass was estimated using three different techniques: circumference, skinfold and ultrasound. Correlation strength among techniques was evaluated and the level of agreement among techniques was determined. Inferential analysis was performed and the percentage error of each technique for each individual was calculated.
Correlation analysis revealed a stronger coefficient between skinfold and ultrasounds than between skinfold and circumferences (respectively, r=0.932 and r=0.686). Delta fat mass percentages were similar, approximately 5%, both when considering skinfold–ultrasound and skinfold–circumference. Stratifying the population by gender, it was observed that the correlation is worse in women than in men. In the case of stratification by BMI, in the ‘Obese’ grouping, the correlation coefficient was small, independent of the technique.
Comparing these techniques has highlighted some critical features of single methods, especially considering specific target populations.
This highlights the importance of the use of coupled techniques or the inadequacy of one with respect to another for particular categories.16 Maggio 2019

Enterococcus is a genus of lactic acid bacteria which normally colonize the intestines of mammals including humans [1]. Enterococci are among the first bacterial colonizers after birth and are able to proliferate in both the large and the small intestine. Enterococcus faecium and Enterococcus faecalis are the most common species of enterococcus found in human feces. However, enterococci can also cause serious infection including sepsis, pneumonia, ophthalmitis, nephritis and osteomyelitis, mainly as complications of various chronic conditions associated with intestinal dysbiosis such as cancer, AIDS or chronic renal failure [2]. Most clinical strains of enterococci belong to the two species E. faecium and E. faecalis, with vancomycin-resistant enterococcal strains (VRE) being the most common cause of lethal infection. Several virulence genes have been discovered in enterococci, allowing the identification of potentially hazardous strains [3]. At the same time, enterococci have a long history, being used as starters for making fermented food products from meat, milk or vegetables [4]. Many enterococcal strains (SF68, M74, LX, etc.) from that group of probiotic strains have been used for a long time as clinically effective probiotics. The current paper summarizes the probiotic effects of one Enterococcus faecium strain—E. faecium L3. This strain was originally isolated from starter culture used in the Russian food industry. The strain was fully characterized microbiologically and genetically and tested for the absence of virulence genes, safety in laboratory animals and it immunomodulatory features. E. faecium L3 has been used in Russia in several probiotic products such as Laminolakt and Bakfir for the last 20 years. The benefits of the strain have been shown in several randomized clinical studies, including some where it was used for the treatment of gastrointestinal diseases such as chronic gastritis, gastric ulcers, irritable bowel syndrome, pancreatitis and chronic hepatitis [5– 7]. In addition to other clinical effects such as anti-cancer properties, a significant cholesterol-lowering activity was also shown [8].9 Maggio 2019

The objective of this study was to determine the influence of socioeconomic status on the body mass index (BMI) of primary school children. A cross-sectional study was conducted with a sample of 280 children aged 6 to 11 years allocated to three groups based on BMI: underweight, ideal weight and overweight/obesity. Socioeconomic status was determined based on the responses of parents/caregivers to a specific form. Data analysis involved the employment of the Kruskal–Wallis, Mann–Whitney U and chi-square tests as well as simple and multiple linear regression analyses. In the final multiple regression model, BMI was influenced by monthly household income (coef=0.223; CI: 1.014 to 1.503). Children from families with a higher monthly income had a higher BMI.9 Maggio 2019

Recent data demonstrate that disruption of the intestinal microbiocoenosis might be the cause of several neurological diseases, including multiple sclerosis (MS). MS is a chronic disease of the central nervous system, where the nervous tissue is damaged by the individual's own immune system. The autoimmune character of MS is largely supported by the positive effects of treatment aimed at suppressing the activity of aggressive immune cells. Since probiotics have an immunomodulatory effect, they can not only correct dysbiosis, but also provide a complex immunomodulatory effect on MS. Enterococcus faecium L-3 is one of the probiotic strains which has been shown to have a protective effect on the course of the disease induced in the animal model of MS (known as experimental allergic encephalomyelitis; EAE). The purpose of this study was to compare the effects of different doses of E. faecium L-3 on the course of EAE in rats. EAE was induced by a single subcutaneous injection of a homologous spinal cord emulsified into complete Freund's adjuvant. It is shown that the extent of the protective action of E. faecium L-3 depends on the dose used, with the greatest effect on reducing the severity of EAE observed with a dose of 8.0 lg CFU/ml. Amelioration of the course of EAE in rats receiving the probiotic was accompanied by decreased inflammation and reduced damage to neurons in the spinal cord. Research shows that the use of E. faecium L-3 at an optimum concentration of bacteria may be beneficial for patients with MS.27 Gennaio 2018

The gastrointestinal microbiota plays a key role in human health. Over the past few decades, a lot of
attention has been directed at improving health by modulating the gut microbial composition using
probiotics. In vivo studies have limitations in providing mechanistic insights into the effect of probiotics
and cannot be used to screen numerous test compounds. However, in vitro approaches can be
used for mechanistic research under highly controlled environmental conditions. Here we describe
how the Simulator of the Human Intestinal Microbial Ecosystem (SHIME®) can be used to produce
data complementary to in vivo studies to help elucidate the mode-of-action of probiotics in the gastrointestinal
tract.26 Gennaio 2018

Legumes are good sources of protein and are rich in lysine and tryptophan, which are limiting amino
acids in cereals. Common legumes include sugar beans, soya beans and cowpeas. Although soya
beans are an important commercial legume, cowpea (Vigna unguiculata L. Walp) varieties grown
by some communities in developing countries have many food and non-food uses. The objective of
this study was to determine the effect of soaking, dehulling and boiling on the protein, polyphenolic
and antinutrient content of cowpea varieties, namely CBC2 and CBC4. Phenols, tannins, flavonoids,
alkaloids and saponins were present in the cowpea varieties. Boiling caused a significant (p≤0.05)
decrease in the protein content of both cowpea varieties. Soaking for 24 hours resulted in an insignificant
(p>0.05) change in the protein content of CBC2, but significantly (p≤0.05) decreased the protein
content of CBC4. On the other hand, dehulling seeds soaked for 6 hours resulted in a significant increase (p≤0.05) in the protein content
of both varieties. Boiling caused a significant decrease (p≤0.05) in total phenolic content (TPC), total flavonoid content (TFC), and content
of condensed tannins and saponins in both cowpea varieties. Also, soaking for 6, 12, 18 and 24 hours significantly (p≤0.05) decreased the
content of these phytochemicals. The greatest losses in TPC, TFC, condensed tannins and saponins for both varieties were observed in seeds
soaked for 6 hours and dehulled samples. The results of this study show that boiling, soaking and dehulling reduced the protein, polyphenolic
and antinutrient content of the cowpea varieties.25 Gennaio 2018

The treatment of breast cancer is complex, with a wide variety of surgical, radiotherapeutic, chemotherapeutic,
biological and endocrine options available. Although these therapies have improved survival
rates, adjuvant treatment does have side-effects. The main adverse effects, such as vasomotor
symptoms, classically represented by hot flushes and night sweats, are related to anti-hormone therapy,
which aims to block the estrogen receptor or destroy estrogen-producing tissue. Options generally
include selective estrogen receptor modulators (SERMs), GnRH analogues and aromatase inhibitors,
which all cause climacteric symptoms in most breast cancer survivors and have a big impact on their
quality of life and treatment compliance. Classically, hormone replacement therapy (HRT) has been
the gold standard treatment for menopausal hot flushes. However, this treatment has risks, and should
not be the first option in women with breast cancer or at high risk of developing the disease. Many alternatives to HRT such as tibolone,
phytoestrogens and antidepressants have been proposed in recent decades, but results have been controversial regarding efficacy and safety,
and consequently compliance is poor. Therefore, interventions to improve compliance with adjuvant hormonal therapy are required. Black
cohosh or Cimicifuga racemosa isopropanolic extract (Remifemin®) is a herbal medication frequently used for alleviating menopausal symptoms.
Several recent studies have shown that patients with mild menopausal symptoms usually experience spontaneous remission after taking
black cohosh, while those with moderate to severe symptoms may experience some benefit. No adverse effects or estrogen activity were
reported with this compound. This review examined the effectiveness of black cohosh extract for relieving symptoms and improving quality
of life in breast cancer survivors and high-risk women with moderate to severe menopausal symptoms.24 Gennaio 2018

Gut microbiome variations have been described in several skin disorders, including atopic dermatitis
in children and psoriasis in adults. In both pathologies, an increase in blood markers for oxidative
stress and inflammation has also been detected. Taking these results into account, we have developed
specific blends of probiotics for each of these skin conditions which have also been studied in clinical
trials. The results have shown that nutritional supplementation with these functional ingredients can
improve the treatment of such skin disorders.23 Gennaio 2018

The complete and undisturbed healing of bone fractures is a key priority for surgeons and patients, so
intensive efforts are made to improve bone healing with a variety of approaches. Oral therapies with
collagen peptides are a relatively new therapeutic approach.
In this observational study, the impact of collagen peptides on bone healing was investigated in a
group of 28 (14 verum/14 placebo) patients of both genders with different fracture locations. Some
patients underwent surgery, while others were treated conservatively. The patients who received bioactive
collagen peptide treatment (FORTIBONE®) had a clearly better outcome regarding bone healing
than the placebo group, half of whom showed suboptimal or bad results. No side effects or intolerance
to the product were reported.
The results of this investigation confirm the positive impact of collagen peptides on bone healing. The data suggest that FORTIBONE® can be
used to improve fracture healing, even in cases where a normal outcome is expected, and to achieve faster healing.22 Gennaio 2018

Human milk oligosaccharides (HMOs) comprise a large family of extremely diverse oligosaccharides
present in high concentrations and which generate a multitude of biological responses. They are generally
considered to have a beneficial effect upon the establishment of the microbiota in infants, but
they also exert this effect in adult humans. They can impede the attachment of pathogens and toxins
such as Campylobacter jejuni, Escherichia coli, Vibrio cholerae, Salmonella fyris, Helicobacter pylori,
bacterial toxins, Entamoeba histolytica and viruses, to the epithelial cells of the gastrointestinal tract.
This in effect reduces their pathogenicity as binding to receptors on the epithelial cells is a prerequisite
for infection by pathogens. If the pathogens or toxins bind to the HMOs they will be removed from the
gastrointestinal tract and not cause disease. Therefore, HMOs are putative protective agents against
enteric infections in adults as well as in infants. HMOs are also useful as therapeutic or preventive
adjuncts in gut motility disorders and gut pain, and possibly also have beneficial effects in reducing
food allergies. Hence, dietary manipulation by the use of HMOs represents a strategy to promote a beneficial gut microbiota and provide
health benefits to human adults as well as to infants.21 Gennaio 2018

Many bifidobacterial strains are currently exploited as probiotic, or health-promoting, bacteria by
the food and pharmaceutical industries. However, the molecular mechanisms responsible for these
beneficial effects on human health are generally poorly investigated and not properly understood.
Therefore, the health-promoting activities of probiotic bacteria must be clinically investigated in order
to satisfy regulatory agencies and to address public demands for effective and scientifically supported
probiotic therapies. Here, we describe the current situation regarding Bifidobacterium bifidum strain
PRL2010, and discuss evidence supporting its use as an effective probiotic for infants and expectant
mothers.20 Gennaio 2018

Bacterial CST (community state type) I is characterized by
Lactobacillus crispatus dominance and is associated with a
healthy vagina and a reduced risk of vaginosis, vaginitis, preterm
birth, infertility and vaginal atrophy. On the other hand,
CST IV is characterized by the absence of lactobacillus and
is associated with unhealthy gynaecological conditions. Unfortunately,
very few L. crispatus strains have been properly
studied and documented for human use. Here we discuss
the genetic, probiotic and vaginal colonization properties of
strain M247, isolated in 1989 from infant faeces, and describe
its possible gynaecological uses especially in woman
characterized by CST IV.19 Gennaio 2018

Its high nutritive quality and ability to survive in harsh conditions makes pearl millet a suitable crop
for arid and semi-arid regions, but anti-nutrient factors reduce the bioavailability and digestibility of
its nutrients. Fermentation reduces anti-nutrients and hence increases protein digestibility and mineral
bioavailability. Thus, the present work examines the effects of fermentation on the nutritive, physiochemical
and functional properties and anti-nutrient composition of pearl millet flour. Natural fermentation
at 20°C, 25°C and 30°C and pure culture fermentations with Saccharomyces cerevisiae, Saccharomyces
diastaticus, Lactobacillus fermentum and Lactobacillus brevis were performed. Analysis
revealed an increase in moisture and fat content and a decrease in protein content following all types
of fermentation. Although the variation in protein levels in different fermentations was not significant,
ranging from 10.29% to 9.83%, the effect on thiamine content was significant as it decreased with
an increase in temperature in the range 20–30˚C in natural fermentation but was increased in pure culture yeast fermentations as compared
with bacterial fermentations at their favourable temperatures, respectively. Total soluble sugar content decreased in pure culture fermentation
but increased in natural fermentation. Fermentation decreased pH, thereby increasing titratable acidity. Oil and water absorption capacities
were increased, while least gelation concentration was decreased in all types of fermentations. Also, anti-nutritional factors like tannins and
phenolic compounds were significantly decreased in all fermentations. We conclude that fermentation is an efficient process to improve the
quality of pearl millet flour.18 Gennaio 2018

Five bar samples, including a control bar, prepared from different percentages of mahua flower syrup
were investigated using fuzzy logic sensory analysis. These bar samples were ranked against each
other: the quality attributes of the bars (colour, flavour, stickiness, overall acceptability and taste) were
scored and the bars rated. A panel of 15 judges performed the sensory evaluation. Analysis indicated
that taste, overall acceptability and flavour were the main quality attributes, while stickiness and colour
were less important. Fuzzy logic sensory analysis determined that the bar with 100% replacement
of sugar with mahua flower syrup was the most acceptable.18 Gennaio 2018

Silymarin, a flavanolignan-containing standardized extract obtained from the fruits of Silybum marianum,
is a traditional phytotherapic product widely used for the treatment of liver diseases including
hepatitis , cirrhosis and bile secretion dysfunction. Recent preclinical data and some clinical investigations
also support its use in the management of non-alcoholic fatty liver disease (NAFLD). Despite this
evidence, silymarin efficacy has not yet been supported by clear-cut dose-related pharmacokinetic
data, although several attempts have been made to enhance the oral absorption of flavanolignans, its
putative active principles. However, positive results have been obtained with lecithin-based formulations
(Phytosome®) of silybin, the main flavanolignans in silymarin, which showed improved oral
absorption in preclinical and clinical trials. The Phytosome® delivery system has also been applied to
silymarin with promising preclinical results consistent with the oral bioavailability of most of the flavanolignans present in the extract. These
data may help optimize the dose for clinical efficacy in liver protection and also pave the way for the use of silymarin in new therapeutic
areas where recent findings indicate a major role for the entire phytocomplex.17 Gennaio 2018

Pyrroloquinoline quinone (PQQ) is a novel vitamin-like compound that acts as an essential active
factor in the functioning of mitochondria. However, as higher organisms do not seem to biosynthesize
PQQ, the major source in humans is the diet. In addition to its role in mitochondria, PQQ stimulates
growth and serves as a cofactor for a special class of enzymes involved in cellular functions including
cellular growth, development, differentiation and survival. It also has possible pharmacological
effects via activation of AMP-kinase (AMPk). Given the nutritional importance and numerous physiological
effects of PQQ, there are many possible clinical applications. The most obvious are those
chronic degenerative conditions that revolve around low mitochondrial function and aging, including
degenerative neurological disease (e.g., Alzheimer’s and Parkinson’s disease), chronic inflammation,
metabolic syndrome and obesity. It also holds promise as a clinical aid for simply improving energy
levels and cognition. This review will highlight the pharmacology, clinical applications and dosage
recommendations for this promising natural product.16 Gennaio 2018

Human milk oligosaccharides (HMOs) are unique oligosaccharides found in mother’s milk. Collectively,
HMOs constitute the third largest solute in human milk, after lactose and fat. The types and
levels of HMO vary considerably among women, geographical regions and the stages of lactation.
Over 130 different oligosaccharides have been identified in human milk, with 2’-fucosyllactose (2’-FL)
being the most abundant (~2 g/l). Recent innovations and regulatory approvals have enabled infant
formula companies to incorporate 2’-FL into their products, helping infant formulas to become more
like mother’s milk. This article explores the latest research on HMOs and their role in supporting digestive,
immune and cognitive development in infants.15 Gennaio 2018

Human milk is a rich source of components that contribute
to shaping the infant gut microbiota through a variety of
mechanisms. After lactose and lipids, human milk oligosaccharides
(HMOs; Fig. 1) are the third most abundant components
of human milk. One litre of mature human milk contains
5–20 g of these complex sugars, which often exceeds
the amount of all human milk proteins combined. Oligosaccharide
concentrations in colostrum are even higher [1].
To date, the molecular structures of more than 100 different
HMOs have been characterized, but it is important to note
that total amount and composition are highly variable between
different women.14 Gennaio 2018

Even though cinnamon oil (CO) has functional and health effects in humans because of the presence
of the antioxidant cinnamaldehyde (CIA), its food applications have been limited due to its poor water
solubility. Encapsulation of CO in stable nanodroplets is a unique strategy to enhance the stability and
bioavailability of hydrophobic molecules in the CO structure. A literature review has been conducted
on the formation of stable nanoscale droplets using low- and high-energy nanoemulsification methods,
physicochemical and antimicrobial characterization, and the food application efficiency of CO
micro/nanoemulsions. Although high-energy emulsification technologies are more commonly used to
produce CO nanoemulsions, there is considerable interest in the fabrication of these delivery systems
using the low-energy techniques of spontaneous emulsification and phase-inversion temperature. Processing
and formulation (oil phase composition and surfactant content) variables were optimized to
produce the smallest droplet size and slowest CIA release rate. Cinnamon and CIA nanoemulsions
can effectively control pathogens in functional foods during processing and storage. A strong inhibitory
effect on many microorganisms can also be exerted by small nanodroplets encapsulating these bioactive compounds into edible films
to significantly decrease the synthetic preservative content. The antibacterial and antifungal activity, nutritional value and physicochemical
quality of foods can be improved by adding CO-enriched nanoemulsions.13 Gennaio 2018

Osteo-articular diseases affect many elderly people, resulting in worse quality of life and a substantial
public health cost. Osteoarthritis, inflammatory articular diseases and conditions associated with
cartilage disruption are the most frequently diagnosed. Non-steroidal anti-inflammatory drugs, glucocorticoids
and physiotherapy are used to treat affected patients, while some nutraceutical products
containing chondroprotective and osteotropic substances have been shown to improve their signs
and symptoms. However, the true absorption and efficacy of these substances in humans is largely
unknown. The absorption of hyaluronans and chondroitin sulfate is likely negatively affected by their
high molecular weight. Nevertheless, many published papers have reported significant improvements
in symptoms and articular functionality in patients taking these compounds. This paper attempts to
clarify the apparent dichotomy between absorption and efficacy, and compare the clinical evidence
for the bioavailability of hyaluronic acid with that of its precursor N-acetyl glucosamine.12 Gennaio 2018

Functional dyspepsia (FD), a gastrointestinal disorder characterized by pain or a burning sensation in the
epigastrium, postprandial fullness, early satiety, bloating and nausea, used to be treated with prokinetics
such as metoclopramide, cisapride and domperidone. Unfortunately, these drugs have severe side effects,
including cardiac and sudden death, and consequently are now rarely used or have been withdrawn
from the market. However, botanicals could be a source of natural prokinetics which do not have these
adverse effects. Perilla frutescens leaf extract is a possible candidate, with some data indicating a clinical
role in FD. As with any botanical, perilla extract normally consists of a complex mixture of active
ingredients characterized by different chemical and physical properties, including varying degrees of
solubility in water and/or alcohol. Consequently, selection of the correct solvents is very important for
the preparation of standardized botanical extracts. We have therefore evaluated which solvents, and in
which order, should be used. Our findings show that a first extraction step performed in ethanol (80%) followed by a second extraction step
using warm water results in standardized quantities of both lipophilic and hydrophilic perilla leaf actives such as rosmarinic acid, vicenin-2,
perilla ketone, apigenin, luteolin, and apigenin and luteolin glycosides.11 Gennaio 2018

Beta vulgaris subsp. cicla (BVc, leaf beet) and Beta vulgaris var. rubra (BVr, red beetroot) belong to the
Amaranthaceae family and have been used for centuries as food and medicinal plants. The main bioactive
phytochemicals of BVr are the betalains, a group of water-soluble pigments derived from betalamic
acid, which are divided into two classes: the yellow/orange-coloured betaxanthins (BX) and the red/
violet-coloured betacyanins (BC). The seeds, leaves and roots of BVc are rich in phenolic acids and
apigenin-derived flavonoids, namely vitexin, vitexin-2-O-rhamnoside (VOR) and vitexina-2-O-xyloside
(XVX). We isolated BVc and BVr phytochemicals in our laboratory and tested them individually and in
combination for their anticancer and anti-inflammatory activity. In cancer cells, vitexin flavonoids were
able to induce intrinsic apoptosis, while betalains induced extrinsic apoptosis. Combinations of two or
three molecules exhibited synergistic antioxidant, anti-inflammatory and anticancer activity, particularly
towards hepatic, intestinal and urinary bladder tumours.10 Gennaio 2018

Introduction: Overweight and obesity increase the risk of mortality following the onset of several
diseases generally characterized by oxidative stress. The levels of advanced glycation end-products
(AGEs), a consequence of metabolic disorder and oxidative stress, play an important role in the process,
and their quantification, based on skin autofluorescence (skin AF), could be used for non-invasive
assessment of AGEs.
Aim: To evaluate in overweight subjects the diagnostic use of AGE determination (skin AF detected by
an AGE Reader) for assessing possible correlation between AGEs and some anthropometric/oxidative
indices.
Patients and methods: 51 consecutive overweight participants in a nutritional education programme
were enrolled in this observational cross-sectional study: 39 women (aged 49.69±13.71; BMI
33.12±5.44 kg/m²) and 12 men (aged 56.84±17.84; BMI 33.12±3.11 kg/m²). Glycometabolic and
oxidative parameters were measured using routine laboratory analyzers. Pearson’s correlation coefficient was used for statistical analysis.
Results: Significant correlations were found between the Cardiovascular Risk Index and age (r=0.65; p<0.0001), AGEs (r=0.41; p<0.0001)
and glycosylated haemoglobin (r=0.38; p<0.05); ageing and AGEs (r=0.50; p<0.0001) and glycosylated haemoglobin (r=0.40; p<0.0001);
and C-reactive protein and fibrinogen (r=0.52; p<0.0001), homocysteine and fasting glucose (r=0.47; p<0.0001).
Discussion: Oxidative stress can be assessed by AGE determination. Our findings in overweight subjects highlight interesting correlations between
metabolic-oxidative parameters. Age emerged as the most important indicator of cardiovascular risk and AGE formation. Notably, skin
AF, detected by the AGE Reader (a simple non-invasive clinical tool), can be a useful marker for rapid assessment of dysmetabolic-oxidative
risk in overweight subjects.9 Gennaio 2018

The consumption of dietary proteins from vegetable sources can be very helpful in the dietary management
of hypercholesterolemia. While it is well established that soy proteins can reduce LDL-cholesterol,
particularly in patients with high cholesterolemia, novel protein sources have lately attracted
much interest. Recent studies have clearly established the nutraceutical properties of eggs and egg
peptides, which have significant effects on both cholesterolemia and blood pressure. In the last few
years, extensive studies have shown that lupin and hempseed proteins have good cholesterol-lowering
properties. Lupin, particularly Lupinus angustifolius, is characterized by peptides that can significantly
raise LDL-receptor activity and also reduce PCSK9 levels, thus providing very effective treatment for
hypercholesterolemic patients when used as substitutes or additives for standard drugs. More recently,
hempseed, a protein source rarely evaluated clinically, has been shown to reduce cholesterolemia in
animal models, by inhibiting HMG-CoA reductase activity, upregulating LDL receptors and, surprisingly,
also increasing PCSK9 levels, with an overall profile similar to that of statins. These novel additions
to the nutraceutical armamentarium for treating raised cholesterol may lead to exciting progress
in the management of hypercholesterolemic patients.8 Gennaio 2018

In 2017, I wrote an editorial on the possible inefficacy of
curcumin [1]. Recently, the possible effect of curcumin on
the gut microbiota has been discussed. Curcumin is a polyphenolic
compound with a long history of use as a dietary
spice, food-colouring agent and herbal remedy. Curcumin
exhibits anti-inflammatory, antioxidant, anticancer, antiviral
and neurotrophic activity and therefore holds promise as
a therapeutic agent to prevent and treat several disorders.
However, a major barrier to curcumin’s clinical efficacy is
its poor bioavailability. Efforts have therefore been made to
develop curcumin formulations that have greater bioavailability
and systemic tissue distribution. Nevertheless, curcumin’s
potential as a therapeutic agent may not solely rely
on its bioavailability but also on its positive influence on
gastrointestinal health, function and structure.7 Gennaio 2018

Background: Since barley possesses various components beneficial to health, replacement of wheat
flour with barley flour in bakery products could be an attractive approach. Hence, the objective of this
study was to replace wheat flour with barley flour for the preparation of cakes.
Materials and methods: Test blends were obtained by incorporating barley flour into wheat flour at
20%, 30%, 40% and 50% levels of substitution and the physiochemical and pasting properties of the
blended flour were studied. The study also investigated the physical, baking and sensory characteristics
of the cakes.
Results: There was a slight increase in protein content from 8.4% to 9.6% and a reduction in moisture
content from 13.57% to 11.27% with increasing levels of barley flour. Pasting properties showed significant
differences among the samples, with a slight increase in pasting temperature and significant variations in stirring number. The baking
time, symmetry index and volume index of cakes decreased with increased barley flour content, but there was no change in organoleptic
properties.
Conclusion: Wheat flour can be replaced with up to 50% barley flour with little decline in the quality parameters of cakes.6 Gennaio 2018

The preference for healthier and convenience food products has resulted in a demand for reducedcalorie
chocolate which has 20% fewer calories than conventional chocolate but the same brightness,
aroma, flavour and hue. The fat replacers used in reduced-calorie chocolate are usually derived from
vegetable oils and/or polysaccharides. The vegetable oils include palm oil, corn oil and soybean oil,
while the polysaccharides include carrageenan, guar gum and locust bean gum. Gums are considered
healthier than vegetable oils but result in a weaker texture. Therefore, vegetable oils are often used
in combination with gums to improve the rheological characteristics of reduced-calorie chocolate.
Sucrose substitutes include sugar alcohols, dietary fibres, syrups and natural/artificial sweeteners. Sucralose
is by far the preferred artificial sweetener because of its stability at higher temperatures. The
incorporation of fat and sugar replacers increases the viscosity and slipperiness of reduced-calorie chocolate. Also, reduced-calorie chocolate
is more bitter and less sweet than conventional chocolate.5 Gennaio 2018

Introduction: Autism is a neurodevelopmental condition of unknown aetiology which is usually diagnosed in the first 3 years of life. Several studies have linked reduced intake of some nutrients with autism and autism spectrum disorder (ASD). Objective: To identify nutritional risk factors that predispose to autism among preschool and school children living in Al-Madinah Al-Monawarah city in Saudi Arabia. Method: Thirty children with autism/ASD aged 2–12 years and 36 matched control children were compared regarding BMI and food intake, using 24-hour recall and a food frequency questionnaire. Results: Both groups consumed similar amounts of carbohydrates, protein and other nutrients, many of which were below the international recommendations for children of their age. However, children with autism/ASD also consumed significantly less omega-3 and iron than the control group. Conclusions: Children with ASD, like other children in Saudi Arabia, consume less than the recommended amounts of some nutrients. Autistic children have reduced intake of omega-3 and iron, together with limited intake of many food varieties which could be linked to autism in susceptible children.4 Gennaio 2018

Background: Nutrition during pregnancy affects the health of the mother and the health and development
of the fetus. The aim of this study was to evaluate the effect of a nutrition education program on
the diet of pregnant women.
Methods: A total of 120 pregnant women (intervention group: 62, control group: 58) attending our
centre at 16–35 weeks of pregnancy were enrolled in our study. A pretested questionnaire was used to
collect data on demographics, job, age, medication use and educational level, and food records were
collected weekly. Three similar educational sessions were held each week for 12 weeks. Data analysis
was performed using SPSS software (version 16).
Results: There were significant improvements in diet diversity (p=0.0001) and nutrient intake (p≤0.05) in the intervention group after the
educational program.
Conclusion: Nutrition education can improve the diet of pregnant women.3 Gennaio 2018

Vitamins are key to human health. Although vitamins are involved in several metabolic pathways, humans
cannot biosynthesize them except for vitamin D and vitamin B3, so adequate intake in the diet
is crucial. Vitamins are classified as fat-soluble or water-soluble. Fat-soluble vitamins include vitamins
A, D, E and K, while water-soluble vitamins include vitamins B and C. Avitaminosis due to imbalanced
nutrition, disease or genetic impairment leads to disease, but consumption of vitamin supplements or
fortified foods can counteract vitamin deficiency. However, their absorption depends on the type of
meal and food matrix composition. Vitamins A, D and E are mainly influenced by lipid content which
promotes intestinal uptake. Surprisingly, the fat-soluble vitamin K seems to be unaffected by type of
diet, although it has better bioavailability as a food supplement. Water-soluble vitamin absorption is
not significantly affected by prandial status or dietary composition. No data are reported for vitamin C, while the vitamin B group needs
evaluation by coenzyme.2 Gennaio 2018

A recently published paper in Nature [1] stated that 27% of 835 non-antimicrobial drugs have a significative impact on gut microbiota. It is likely that a similar or greater proportion of botanicals have comparable effects. For instance, we know that curcumin increases the abundance of butyrateproducing bacteria and faecal butyrate level [2]. This could explain why, despite its very poor oral bioavailability, curcumin acts as an anti-inflammatory agent and why it is a promising therapeutic option for the treatment of inflammatory bowel disease. Berberine is another excellent example of a botanical which acts by modulating the microbiota. Knowledge of the mechanism by which berberine modulates the microbiota could lead to better understanding of the role of berberine in metabolic diseases.21 Gennaio 2017

This study describes the enhanced and simultaneous extraction of phycocyanin and phenolics from
Arthospira platensis biomass. Ultrasound-assisted solvent extraction was investigated to determine
its efficacy regarding phycocyanin and phenolics yield. An optimization experiment using response
surface methodology revealed that the variables ethanol concentration (20%–95%, v/v), extraction
temperature (15°C–65°C), sonicator amplitude (20%–100%) and extraction time (60–300 s) have a
significant effect on phycocyanin and phenolics yield. The maximum yield of phycocyanin (29.9 mg/g)
and total phenolics (2.4 mg/g) was predicted to occur at 40% ethanol concentration, 34.9°C extraction
temperature, sonicator amplitude of 95% and extraction time of 104.7 s. The resultant extract
exhibited a dose-dependent antioxidant response with an IC50 value of 85.75 μg/ml. This extract can
be incorporated into functional foods as the extracting solvents ethanol and water have GRAS (generally
recognized as safe) status.20 Gennaio 2017

Dhokla is easy to cook and very popular as a snack. Tomato is an excellent fortification ingredient for
food products due to its nutritional properties, high antioxidant activity and good sensory characteristics.
In this study, dhokla was fortified with 1%, 4% and 7% tomato powder and analyzed on the
day of preparation and after storage. Acidity increased from 0.09 to 0.45 following tomato powder
incorporation. The correlation coefficient (R2) demonstrated that antioxidant content is strongly associated
with antioxidant activity. Rheological characteristics suggested that dhokla batter has viscoelastic
properties. The moisture content of dhokla decreased from 16.928 to 15.10, from 18.05 to 17.45 and
from 20.10 to 18.03 at the three levels of fortification after storage. Nutritional values were highest
when dhokla was fortified with 7% tomato powder. Sensory analysis showed that dhokla containing
4% tomato powder has the best overall acceptability.19 Gennaio 2017

Stevia rebaudiana Bertoni extracts are used as natural non-nutritive sweeteners in several countries
worldwide. The principal components of stevia leaf extracts are stevioside and rebaudioside A. Stevioside
has about 300 times the sweetening power of sucrose, but is the main cause of the bitter aftertaste
of crude stevia extracts. Rebaudioside A has greater sweetening power and a less pronounced bitter
aftertaste, and so is usually the preferred component. The overall taste of the sweetener depends on
the composition of the stevia extract used and the steviol glycosides present. To characterize the
unique taste profile of stevia sweeteners, we analyzed stevioside, rebaudioside A, rebaudioside B and
isosteviol content in seven different commercial food-grade extracts used as raw material. A sensitive
method, using HPLC coupled to electrospray ionization-tandem mass spectrometry, was applied. The
amount of steviol glycoside in the seven different extracts varied. As expected, rebaudioside A was the
most abundant, ranging from 497 to 1,000 mg/g. One sample contained only rebaudioside A. Rebaudioside
B and stevioside levels ranged from negligible to 40% of the total glycosides determined, with
concentrations ranging from 2.7 to 386 mg/g of raw material. The concentration of isosteviol was below the limit of detection in all samples.
These data can help in the selection of the most suitable commercial extracts for use as sweeteners in food, beverages and confectionery.18 Gennaio 2017

Hair loss and thinning hair are serious problems affecting a large number of women, especially during
the menopause. A food supplement containing fermented soy, ornithine, arginine and Tricovel®
Tricoage45+ with Bioequolo (Giuliani SpA, Milan, Italy), formulated to promote hair growth in women
over the age of 45, was used in a double-blind, placebo-controlled study conducted in healthy adult
females going through the menopause. Subjects with hair loss and less than 80% of their hair in the
anagen phase were randomized to receive a single daily dose of the study product or placebo. Wash
test results showed that hair loss was significantly reduced after the first 8 weeks of treatment with the
study product. Hair pull test results also showed significant improvements (fewer hairs removed) in
subjects treated with the study product vs. placebo after 8 and 12 weeks of treatment. Moreover, analysis of microscope images revealed
a statistically significant increase in the conversion of vellus hair into terminal hair after 12 weeks of treatment with the study product
compared with placebo. Self-evaluation by the subjects confirmed these improvements. This study shows that the dietary supplement can
decrease hair loss and promote hair growth in women over 45 years of age.17 Gennaio 2017

Syzygium alternifolium (SA) is a plant widely used in folk medicine. The current study was carried
out to characterize the anti-Helicobacter pylori (Hp) and anti-gastric cancer activity of S. alternifolium
fruit extracts. S. alternifolium total phenolics (SATP) and S. alternifolium aqueous extract (SAAE)
were used to examine anti-H. pylori and H. pylori urease inhibitory activity. The anti-gastric cancer
activity of these extracts was also evaluated using an MTT cell viability assay followed by cell cycle
progression analysis. The in vitro results showed that both extracts have dose-dependent anti-H. pylori
and anti-gastric cancer activity. SATP has significant anti-H. pylori activity against the Hp26695 and
HpP12 strains with MIC50 values of 148±20 and 141±30 μg/ml, respectively, while SAAE has moderate
activity compared to the antibiotic amoxicillin. SATP showed significant urease activity with an
IC50 of 98±6.4 μg/ml, while SAAE showed a moderate effect compared with positive control. Moreover, SATP showed significant inhibition
of human gastric adenocarcinoma cell growth by inhibiting the G2/M phase of the cell cycle with an IC50 of 77.9±0.2 μg/ml, while SAAE
exhibited moderate inhibition compared with normal control. Reverse phase UV-HPLC analysis indicated the presence of the phenolic compounds
cinnamic, gallic, ferulic and vanillic acid in these extracts. The results suggest that SATP and SAAE extracted from S. alternifolium
have significant anti-H. pylori and anti-gastric cancer activity and offer protection against gastritis. Hence, these extracts are recommended
for patients with gastrointestinal cancer.15 Gennaio 2017

Helicobacter pylori (Fig. 1), previously called Campylobacter
pylori, is a gram-negative, microaerophilic bacterium
found usually in the stomach. It was identified in 1982 by
two Australian who found it in a patient with chronic gastritis
and gastric ulcers, conditions not previously thought
to have a bacterial aetiology. H. pylori is also linked to the
development of duodenal ulcers and stomach cancer. It is
present in the stomach of 50% of the world’s population and
asymptomatic in over 80% of those infected. The standard
first-line therapy to eradicate H. pylori, is the so-called triple
therapy consisting of proton pump inhibitors (PPI), mainly
omeprazole, along with the antibiotics clarithromycin and
amoxicillin. Variations on the triple therapy have been developed
over the years, using a different PPI, or replacing
amoxicillin with metronidazole for those with an allergy to
penicillin. Due to antibiotic-resistant bacteria, an additional
round of antibiotic therapy, the quadruple therapy, consisting
of a PPI, a bismuth colloid, metronidazole and tetracyclines,
has been developed.14 Gennaio 2017

Different proportions of raw and sprouted barley flour were separately blended with wheat flour and
the mixtures analyzed for their physicochemical and pasting properties. Blending with barley flour
resulted in an increase in protein, fat and ash content. An increase in barley fraction significantly
decreased the bulk, true density and colour (L* and b* values) of blends, while the angle of repose
increased significantly. Incorporation of sprouted barley flour compared with raw barley flour led to
a greater percentage change in the parameters studied: peak viscosity and setback increased, while
peak time and pasting temperature decreased. Blending of wheat flour with sprouted barley flour in
comparison with raw barley flour showed lower increases in peak viscosity and setback values. Flour
blends were then used for the production of cookies that were analyzed for their physicochemical, textural and sensory attributes. Cookies
containing raw barley flour had a higher spread ratio than cookies made from sprouted barley flour blends. Blending with barley decreased
the L* value of cookies, with incorporation of sprouted barley showing a smaller decrease in L* value than raw barley. Hence, incorporation
of sprouted barley resulted in flour blends with improved pasting properties and better quality gluten-free cookies.13 Gennaio 2017

The usefulness of tigernut milk (TNM) in reversing acetaminophen-induced liver injury was investigated.
Twenty-five rats were randomized into five equal groups. Four groups were challenged on day 0
with 2500 mg/kg bodyweight (bw) acetaminophen. Subsequently, from days 1 to 7, they were treated
with 0, 500, 1000 and 2000 kg/mg bw TNM, respectively, per os. The fifth group served as the normal
control group. On the 8th day, the rats were sacrificed humanely and biochemical markers of toxicity
and oxidative stress were determined in their sera. TNM at the tested concentrations significantly
reversed liver injury as shown by liver function markers. For example, serum alkaline phosphatase
(ALP) concentrations decreased dose-dependently and significantly (p<0.001) from 298.9±32.3 in the
negative control group to 159.3±22.1 in the 2000 mg/kg bw TNM group. In fact, the serum ALP concentrations of all test rats were statistically
similar (p>0.001) to those of the normal control rats. These biochemical data are corroborated by histological findings. Superoxide
dismutase activity (U/mg protein) was increased significantly (p<0.001) from 108.0±7.4 in the negative control group to 283.9±20.5 in the
500 mg/kg bw TNM group, and indeed in all test groups. Malondialdehyde concentrations in the test rats suggest less efficient clearance of
the break-down products of lipid peroxidation. Phytochemicals in the TNM may have acted directly as antioxidants, or induced the synthesis
of glutathione (which exerts downstream positive effects on antioxidant systems), thereby aiding recovery from drug-induced liver damage.12 Gennaio 2017

Several compounds are commonly used as flavours in foods such as chewing gum and candy to generate
a pleasant cool sensation which can have a soothing effect on the upper respiratory tract. Menthol
and eucalyptol are the flavours most widely used as cooling agents and their effect is supported by scientific
data. The cool sensory perception they induce is due to their ability to activate cold receptors,
particularly the transient receptor potential cation channel subfamily M member 8 (TRPM8), found
in the skin and oral cavity. The ability to activate cold receptors has been also shown for non-volatile
and non-menthol coolants developed since the 1970s, assessed as Generally Recognized as Safe and
approved for use in food by the Flavor and Extract Manufacturers Association of the United States.
Among these coolants, ethyl 3-(p-menthane-3-carboxamido)acetate, its analogue N-[[5-methyl-2-(1-
methylethyl)cyclohexyl]carbonyl]glycine propyl ester and N-ethyl-p-menthane-3-carboxamide have
demonstrated a greater cooling effect than menthol and are defined as ‘high-intensity cooling agents’.
Studies in human volunteers who consumed flavoured chewing gum found that the flavour intensity of
menthol or eucalyptol, and consequently their cooling effect, increases with chewing and that volatile flavour compounds in the oral cavity
are forced into air exhaled through the nasal compartment. It was thus confirmed that the soothing effect and increased air flow perceived
in the nose and throat are sensations and not pharmacological actions.10 Gennaio 2017

Obesity and overweight are defined as abnormal excess accumulation of fat in adipose tissue, which
is recognized as a real organ with both metabolic and endocrine functions, and have a close relationship
with oncological risk. The relationship between obesity and carcinogenesis is complex and not

chronic inflammation, dyslipidaemia and insulin resistance (generally defined as metabolic disorders)
which contribute to the increased risk of cancer in the overweight population. Current data show that
metabolic disorders are often reversible with prompt therapeutic intervention, so these conditions and
related carcinogenetic pathways should be managed for cancer prevention and therapy. Metformin
and statins have demonstrated their ability to interfere with tumour processes but unfortunately also
produce side effects, making long-term and preventative use difficult. Some nutraceutical compounds seem to be ideal for providing similar
activity and effectiveness as these agents but with minor or absent side effects. This review examines the pathophysiology of metabolic disorders,
their relationship with cancer and the possibility of interfering with associated processes with some promising nutraceuticals used as
monotherapy or in combination with conventional therapies.8 Gennaio 2017

New analysis published in the New England Journal of Medicine
[1] has identified six genomic regions conferring risk of
premature delivery following preterm rupture of membranes
(PROM), which is a major health problem worldwide. The
information obtained may be useful in implementing new
preventive strategies, some of which are simple and inexpensive,
such as the use of selenium dietary supplements.
The study conducted at the Cincinnati Children’s Hospital
Center (USA) as part of an international collaboration identified
six genomic regions that affect the duration of pregnancy
and time of delivery. The study, which involved more than
50,000 women, could have important consequences for the
prevention of premature births and related complications.
Premature births (those that occur before the 37th week of
pregnancy) are an important public health problem globally:
it is estimated that premature birth is the main cause of death
among children under the age of five [2, 3].7 Gennaio 2017

Antioxidants were extracted from oregano leaves (Origanum vulgare L.) using the solvents water, ethanol,
methanol, acetone and diethyl ether. Although a higher extract yield was obtained with water, in
general higher total phenolic and flavonoid content and better antioxidant activity were found in the
extracts prepared using ethanol. The antioxidant potential of the ethanolic extract of oregano leaves
in ghee during storage and frying was evaluated in comparison with the synthetic antioxidants butylated
hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). Three quality parameters, namely
peroxide value (PV), free fatty acid (FFA) content and p-anisidine value (PAV), of ghee were analyzed.
The PV, FFA content and PAV of control ghee samples increased significantly during storage and frying
as compared to the ghee samples containing oregano extract (OGE), BHA or BHT. The frying period
had a greater effect on changes in PV, FFA content and PAV of ghee than the storage period. Ghee samples with added 1.0% (w/w) OGE
showed the least increase in PV, FFA content and PAV, which was comparable with samples with added 0.02% (w/w) BHA and BHT. The
study revealed that oregano leaves could be a good natural source of antioxidants and can be used in ghee to retard oxidative deterioration
during storage and frying.6 Gennaio 2017

The spray dried α-amylase-assisted supercritical carbon dioxide (SC-CO2) extract of small cardamom
(rich in 1,8-cineole) was used for the fortification of custard to obtain a new designer nutraceutical
custard. The encapsulate was employed at concentrations of 4%, 4.5% and 5% (w/w) to formulate the
custards. Custard formulated with 4.5% of encapsulate was most preferred by the sensory panel. This
custard sample showed a more stable texture, higher phytochemical properties and lower microbial
load than the control sample (formulated without encapsulate). This is the first study on the formulation
of a new designer nutraceutical custard by fortification with encapsulated SC-CO2 extract of
small cardamom. The processes described here can safely be employed in the development of other
nutraceutical or functional foods, which inevitably involves the loss of the phytochemicals of food
constituents during manufacture.5 Gennaio 2017

Wheat has been reported to contain a variety of bioactive compounds which have health benefits. The
bioactive compounds, however, are affected by the different processing conditions applied to wheat
flour during the manufacture of different products. Milled wheat is used to produce a variety of baked
products, but the effect of toasting and roasting before milling has not been examined. Therefore, the
effects of mild (toasting) and strong (roasting) heat treatments on the Hunter Lab colour, pasting and
antioxidant properties of flours from commercially important wheat cultivars grown in India were
investigated. Antioxidant properties including total phenolic content (TPC), total flavonoid content
(TFC), antioxidant activity (AOA), metal chelating activity (MCA) and ABTS+ scavenging activity were
studied. Both heat treatments resulted in a reduction in bulk density (BD) and Hunter L* values. However,
Hunter a* and b* values were increased. The AOA, MCA and ABTS+ scavenging activity of flours
increased after both treatments, while TFC was decreased and TPC was increased after toasting but decreased after roasting. All pasting parameters
except pasting temperature increased with toasting but decreased after roasting. Flour from cv.WHD-943 showed the highest AOA,
TPC and ABTS+ scavenging activity both before and after the two heat treatments.4 Gennaio 2017

Objective: To investigate the association of dietary calcium with blood pressure and weight gain in
pregnant women.
Design: This study used data collected from healthcare centres in Ardebil for 137 pregnant women
aged 30–35 years. Dietary calcium intake was assessed using a single 24-hour food recall and Nutritionist
IV software. Height and weight were measured after overnight fasting with all participants wearing
light gowns. Blood pressure measurements were taken in the sitting position after a resting period
of at least 5 min. Linear regression was used to evaluate the relationship of dietary calcium intake with
weight gain and blood pressure.
Results: Mean±SD systolic and diastolic blood pressures were 150.19±50.45 and 70.18±11.16 mmHg, respectively. Mean±SD calcium intake
was 784.59±33.36 mg/day. There was a significant association between dietary calcium intake and diastolic blood pressure and weight
gain in pregnant women (p≤0.05). However, the association between dietary calcium intake and systolic blood pressure and weight was not
significant (p≥0.05).
Conclusion: Dietary calcium intake can affect blood pressure and weight gain in pregnant women.3 Gennaio 2017

A two-step method for sequential optimization was designed based on the role of hydrolytic factors
in the preparation of antioxidative whey protein hydrolysates (WPH). In the first step, the rates of reaction-
related variables such as pH, temperature and the enzyme/substrate (E/s) ratio (w/w) were optimized
to 1.5, 37°C and 1:100 for pepsin, 8, 42°C and 1:100 for trypsin, and 7.8, 37°C and 1:50 for
pancreatin, respectively, with maximum degrees of hydrolysis of 4.5%, 14% and 15.2%, respectively.
In the second step, hydrolysis was performed at the optimum conditions determined in the first step.
The optimum hydrolysis times were 1.5 h for pepsin and 2 h each for trypsin and pancreatin based
on their maximum reducing powers of 0.31, 0.55 and 0.62, respectively. In sequential hydrolysis, the
optimized pepsin hydrolysates with subsequent action of trypsin and pancreatin individually were
optimized at their respective E/s ratios of 1:50 and 1:100 (w/w) based on their respective degrees of
hydrolysis of 13.6% and 14.8%, while the optimum hydrolysis times were 4.5 h and 2.5 h for reducing
powers of 0.66 and 0.75, respectively. This study indicates that sequential optimization for the production of antioxidative WPH could
be better than the traditional one factor at a time (OFAT) method.2 Gennaio 2017

Possible unwanted consequences of antibiotic use include:
(a) the selection of antibiotic-resistant pathogenic bacteria;
(b) increased susceptibility of the host to new infections; (c)
gram-negative bacterial overgrowth; (d) diarrhoea; and (e)
Clostridium difficile colonization [1]. Theoretically, except
for antibiotic resistance, all these effects could be alleviated
with probiotics. However, even a small delay between antibiotic
administration and supplementation with probiotics
severely reduces the positive impact of the probiotics as they
are unable to integrate into the gut microbiota. The high sensitivity
of probiotics to antibiotics prevents stable colonization
of the gut, thus ensuring only non-significant and transient
effects. However, the use of antibiotic-resistant bacteria
could be beneficial. Of course, for safety reasons, this resistance
must not be transferable and must not be located in
plasmid DNA as probiotics could otherwise be responsible
for dangerous horizontal gene transfer (Fig. 1) to pathogens
[2]. Antibiotic-resistant probiotics sound very attractive,
even tempting pharmaceutical companies to falsely claim
some probiotic strains have antibiotic-resistant properties.
