Probiotic ingestion is recommended as a preventive approach to maintain the balance of the intestinal microbiota and to enhance the human well-being. During the whole life of each individual, the gut microbiota composition could be altered by lifestyle, diet, antibiotic therapies and other stress conditions, which may lead to acute and chronic disorders. Hence, probiotics can be administered for the prevention or treatment of some disorders, including lactose malabsorption, acute diarrhoea, irritable bowel syndrome, necrotizing enterocolitis and mild forms of inflammatory bowel disease. The probiotic-mediated effect is an important issue that needs to be addressed in relation to strain-specific probiotic properties. In this work, the probiotic properties of new Lactobacillus and Bifidobacterium strains were screened, and their effects in vitro were evaluated. They were screened for probiotic properties by determining their tolerance to low pH and to bile salts, antibiotic sensitivity, antimicrobial activity and vitamin B8, B9 and B12 production, and by considering their ability to increase the antioxidant potential and to modulate the inflammatory status of systemic-miming cell lines in vitro. Three out of the examined strains presenting the most performant probiotic properties, as Lactobacillus plantarum PBS067, Lactobacillus rhamnosus PBS070 and Bifidobacterium animalis subsp. lactis PBSO75, were evaluated for their effects also on human intestinal HT-29 cell line. The obtained results support the possibility to move to another level of study, that is, the oral administration of these probiotical strains to patients with acute and chronic gut disorders, by in vivo experiments. © 2015, Springer-Verlag Berlin Heidelberg.

During and after menopause the skin shows up clearly how the lack of estrogen affects tissues, and menopause can in fact be considered a "multisystemic" disorder of connective tissue. The low menopausal estrogen levels combined with age-related skin changes, accelerating skin aging. This affects both the epidermis and the dermis: fibroblasts not only become fewer, but they produce 30% less collagen, reflecting its metabolic decline. Estrogens act on collagen synthesis by directly stimulating fibroblasts. However, hormone replacement can prevent the postmenopausal loss of collagen - or eliminate it once it has started. The results of the Women's Health Initiative study drastically changed Italian gynecologists' prescribing habits. Natural products with estrogen-like activity are increasingly accepted, since they have good effects on collagen synthesis and/or inhibit collagenase activity, with a reassuring safety profile. This was confirmed by an in vitro study that assessed the tonic-trophic properties of two treatments on cultured skin fibroblasts. Cells were treated with resveratrol either alone or combined with NAC 10-100-1000 μM. There was a dose-related increase in the rate of cell proliferation and in inhibition of collagenase activity.

Background: As the appearance of the face is a primary concern of many people, ways in which to tighten the skin are increasingly in demand. In recent years, radiofrequency (RF) has become a promising nonablative, non-invasive, technique for facial rejuvenation. Objective: To assess the safety and the efficacy of a unipolar RF-based device for home use in increasing skin tightness (lifting effect) in the eyebrows area. Methods: Subjects (N = 50) aged between 30 and 70 years old showing skin wrinkledness all over the face and skin laxity in the eyebrows area were enrolled. The primary endpoint was the assessment of the eyebrow to hairline distance by means of a morphometric digital image analysis technique. Results: The eyebrows to hairline distance was statistically significant (both vs. basal condition and placebo) decreased by 1.338 ± 0.170 cm in the treated eyebrow. Conclusion: The obtained results confirm the safety and the efficacy of the tested device in decreasing skin laxity in the eyebrows area. The treatment is not time-consuming (about 6 minutes) and can be done at home. The device seems to be then a useful tool to delay skin laxity or to prolong the time to the first surgical facial lift. © 2016 Taylor & Francis Group, LLC.

Oxalate (Ox) is a very common component of the human diet, capable to collect in the renal tissue and bind calcium to form calcium oxalate (CaOx) crystals. A supersaturation of CaOx crystal may cause nephrocalcinosis and nephrolithiasis. The inflammation derived from the CaOx crystal accumulation, together with innate or secondary renal alterations, could strongly affect the renal function. In this case a consumption of probiotics with either oxalate-degrading activity at intestinal level and systemic anti-inflammatory activity could be an alternative approach to treat the subjects with excess of urinary oxalate excretion. 11 strains of lactic acid bacteria (Lactobacilli and Bifidobacteria), already included in the list of bacteria safe for the human use, were investigated for their capability to degrade oxalate by mean of RP-HPLC-UV method and modulate inflammation in an in vitro model system based on peripheral blood mononuclear cells. Four promising bacterial strains (Lactobacillus plantarum PBS067, Lactobacillus acidophilus LA-14, Bifidobacterium breve PBS077, Bifidobacterium longum PBS078) were identified as innovative biological tools for the prevention and the therapeutic treatment of hyperoxaluria and the inflammatory events associated to the Ox accumulation. © 2014 Institute of Food Technologists®.

Growing evidence is rising about the potential of a conscious and responsible nutrition to promote health and reduce cardiovascular risk. Weight management and healthy life-style are the primary approach. The current article provides the scientific rational for the use of dietary supplementation based on standardized apple polyphenols to control of calories intake by reducing sugars and carbohydrates absorption. In vitro data are reported, showing the superior antioxidant and hypoglycaemic activity of an apple complex named PCQ, with respect to other standard references. A human trial was run to confirm PCQ capacity to reduce glucose concentration, to slow down its absorption rate, to decrease the glycaemic index and promote the satiety effect.

General skincare measures such as the use of moisturisers and products containing adequate photoprotection are important components of acne patients management to complement the pharmacological regimen. Acne RA-1,2 is a novel dermato-cosmetic product which contains selective photofilters and active ingredients against the multifactorial pathophysiology of acne.To evaluate the tolerability of Acne RA-1,2 and its effect on the clinical signs of acne.This double-blind, placebo-controlled study randomized 40 adult patients with 10-25 comedones per half face to once-daily application of Acne RA-1,2 or placebo for 8weeks. Evaluations after 4 and 8weeks included the number of comedones, transepidermal water loss (TEWL), sebum production, and tolerability.In the Acne RA-1,2 group, there was a significant 35% decrease in the mean number of comedones from 26 at baseline to 17 at Week 8 (P<.001), a 7% significant reduction in TEWL (9.32 to 8.66g/h/mAcne RA-1,2 was well tolerated and effective at reducing comedones and sebum production and improving epidermal barrier function. These results suggest that Acne RA-1,2 is useful against acne-prone facial skin, particularly as it targets sebum production, which topical pharmacological acne therapies do not address.

The aim of this study was to evaluate in the vagina of 60 pre-menopausal women the detection of orally administered multispecies probiotic formulations showing anti-microbial properties in test in vitro.A randomized, double-blind, three-arm parallel pilot study was carried out on 60 pre-menopausal women. Subjects were randomly divided in three groups (F_1, F_2, F_3). Each group received a daily oral administration of probiotic mixtures (for 14days and at the day 21, 7days after the wash-out) containing: Lactobacillus acidophilus and Lactobacillus reuteri (F_1), or Lactobacillus plantarum, Lactobacillus rhamnosus and Bifidobacterium animalis subsp. lactis (F_2), or placebo (F_3), respectively. Vaginal swabs were collected at four experimental times, at t0 and at t7, t14 and t21days, and analyzed by qPCR. At the same time, the anti-microbial activity of the probiotic formulations was verified by assays in vitro against microorganisms as Escherichia coli and Candida albicans.L. acidophilus and L. reuteri as well as L. plantarum, L. rhamnosus and B. lactis were significantly increased on 7days in the groups administered with F_1 and F_2, respectively, compared to group F_3. A similar significant trend was observed on 21days, 7days after the wash-out. F_1 and F_2 showed coherent anti-microbial properties.Both probiotic formulations F_1 and F_2, chosen because of their anti-microbial activity against pathogens responsible for vaginal dysbiosis and infections, led to vaginal detection and enhancement of the amount of species of formulates when orally administered. This work provides the basis for further clinical investigations of the F_1 and F_2 capacity to prevent or treat uro-genital infections.

The paper describes the preparation of new probiotic formulations based on chitosan-coated alginate microcapsules containing three different probiotic strains, Lactobacillus plantarum PBS067, Lactobacillus rhamnosus PBS070, and Bifidobacterium animalis subsp. lactis PBS075 taken individually and as a mixture of them. The effects of microencapsulation on the viability of the strains in conditions simulating the gastrointestinal tract and under industrial processes conditions were studied. In addition, an evaluation of their probiotic properties was also investigated by in vitro tests on the human intestinal cell line HT-29 to explore the effect of microencapsulation on health beneficial effect of the considered strains. Non-encapsulated cells were completely destroyed when exposed to simulated gastric juice and other stress conditions, while encapsulated cells exhibited a significantly higher resistance to artificial intestinal juice and heat and osmotic treatment. Moreover, in this study, the effect of the various microencapsulated probiotic strain formulations was compared with analogous formulations also containing the -glucan Pleuran. The microencapsulation effectively protected the selected bacteria, as single strain and as a mixture of the three strains in both the formulations with and without Pleuran, from simulating gastrointestinal tract and industrial process conditions in delivering the viable cells without any significant adverse effect on their functionalities. The comparative study of the immunomodulatory properties of each single strain and the mixture of the three strains revealed a synergistic effect of the probiotic mixture, but no appreciable difference between the two kinds of formulations could be detected, as the effect of Pleuran is covered by the higher potential of the probiotic strains.

This study was designed to evaluate the effects of equol and resveratrol supplementation on health-related quality of life (HRQoL) in otherwise healthy menopausal women with hot flashes, anxiety and depressive symptoms.Sixty recently menopausal women aged 50-55 years were randomized in a 12-week, placebo-controlled trial to receive 200mg of fermented soy containing 10mg of equol and 25mg of resveratrol (1 tablet/day). The primary outcome was the change in score on the Menopause Rating Scale (MRS), used to evaluate the severity of age-/menopause-related complaints. Additional outcome measures included the subject-reported score on the Hamilton Rating Scale for Depression (HAM-D) and Nottingham Health Profile (NHP), which was used specifically to assess sleep quality.The symptoms assessed by the MRS improved during treatment in the active group. Comparison between placebo and treatment groups revealed statistically significant improvement in particular for dryness of vagina (-85.7%) (p<0.001), heart discomfort (-78.8%; p<0.001) and sexual problems (-73.3%; p<0.001). On the HAM-D significant improvements at week 12 were seen in work and activities (-94.1%) (p<0.001). Subjects treated with equol and resveratrol also had significant differences in the sleep domain of the NHP (p<0.001).These findings provide evidence that 12 weeks of dietary supplementation with equol and resveratrol may improve menopause-related quality of life in healthy women.

Background and Aim. The efficacy of supplementation treatment with two multispecies probiotic formulates on subjects diagnosed with IBS-C and the assessment of their gut microbiota were investigated. Methods. A randomized, double-blind, three-arm parallel group trial was carried out on 150 IBS-C subjects divided into three groups (F_1, F_2, and F_3). Each group received a daily oral administration of probiotic mixtures (for 60 days) F_1 or F_2 or placebo F_3, respectively. Fecal microbiological analyses were performed by species-specific qPCR to assess the different amount of probiotics. Results. The percentage of responders for each symptom was higher in the probiotic groups when compared to placebo group during the treatment period (t60) and was maintained quite similar during the follow-up period (t90). Fecal analysis demonstrated that probiotics of the formulations increased during the times of treatment only in fecal DNA from subjects treated with F_1 and F_2 and not with F_3, and the same level was maintained during the follow-up period. Conclusions. Multispecies probiotic supplementations are effective in IBS-C subjects and induce a different assessment in the composition of intestinal microbiota. This clinical study is registered with the clinical study registration number ISRCTN15032219.
