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.

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.

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®.

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 β-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. © 2015, Springer-Verlag Berlin Heidelberg.

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.
