Abstract
Young barley seems to be a promising material for use as nutricosmetic due to the presence of many biologically active compounds. The aim of this study was to evaluate the effect of Hordeum vulgare L. extracts on human skin fibroblasts exposed to ultraviolet radiation B (UVB) radiation. Analysis of the chemical composition showed a predominance of 9,12,15-octadecatrienoic acid. The quality assessment showed that young barley preparations have high total polyphenolic content (TPC) and favourable total antioxidant status (TAS). They also contain antioxidant elements such as zinc, copper, and selenium. Furthermore, the analyzed products were found to be safe in terms of toxic elements (lead, cadmium and mercury) and lack of cytotoxic effect of young barley extracts on cells. In vitro bioactivity assays showed that young barley extract increased the survival rate and accelerated the migration of fibroblasts in research models with UVB radiation. The application of both extracts caused an increase in DNA biosynthesis, and in the number of cells arrested in S phase. Moreover, an inhibitory effect of the tested extracts on the expression of matrix metalloproteinase 2 (MMP-2) and matrix metalloproteinase 9 (MMP-9) was observed. The results indicate that young barley extracts, due to protective as well as restorative effect, could potentially be used in the production of nutricosmetics and skin care products.

Abstract
The previous research reported the results of a prospect cohort study that used logistic regression analysis to construct a risk prediction model for skin tears in individuals aged over 65 years. The model identified three baseline individual characteristics (male gender, history of STs, and history of falls) and two baseline skin manifestations (purpura and elastosis) that predicted the risk of dorsal forearm skin tears. This paper outlines the relationships between baseline skin manifestations and the risk of skin tears. Univariable logistic regression analysis was conducted of all the baseline data collected from the same-study participants to identify variables that significantly predicted purpura and elastosis at baseline. Amongst the 173 participants, 71 (41%) developed one or more skin tears, and in these participants, 52 (73.2%) displayed purpura, 41 (57.8%) had elastosis, and 30 (42.3%) exhibited both manifestations of the dorsal forearm at baseline. Four individual characteristics (age, history of skin tears, history of falls, and antiplatelet therapy) and three skin properties (pH, subepidermal low echogenicity band of the forearms, and skin thickness) were found to predict the risk of purpura. Conversely, three individual variables (age, gender, and smoking), three clinical skin variables (uneven skin pigmentation, cutis rhomboidalis nuchae, and history of actinic keratosis) and one skin property variable (collagen type IV) predicted the risk of skin elastosis. Progressive changes to the skin's structural and mechanical properties from the underlying effects of chronological ageing, and environmental and lifestyle-related influences increased the risk of purpura and elastotic skin manifestations and concomitantly increased risk of skin tears amongst participants.

Abstract
Full expression of reflex cutaneous vasodilation (VD) is dependent on nitric oxide (NO) and is attenuated in older humans. NO may be decreased by an age-related increase in reactive oxygen species or a decrease in l-arginine availability via upregulated arginase. The purpose of this study was to determine the effect of acute antioxidant supplementation alone and combined with arginase inhibition on reflex VD in aged skin. Eleven young (Y; 22 ± 1 yr) and 10 older (O; 68 ± 1 yr) human subjects were instrumented with four intradermal microdialysis (MD) fibers. MD sites were control (Co), NO synthase inhibited (NOS-I), l-ascorbate supplemented (Asc), and Asc + arginase-inhibited (Asc + A-I). After baseline measurements, subjects underwent whole body heating to increase oral temperature (Tor) by 0.8°C. Red blood cell flux was measured by using laser-Doppler flowmetry, and cutaneous vascular conductance (CVC) was calculated (CVC = flux/mean arterial pressure) and normalized to maximal (CVCmax). VD during heating was attenuated in O (Y: 37 ± 3 vs. O: 28 ± 3% CVCmax; P < 0.05). NOS-I decreased VD in both groups compared with Co (Y: 20 ± 4; O: 15 ± 2% CVCmax; P < 0.05 vs. Co within group). Asc and Asc + A-I increased VD beyond Co in O (Asc: 35 ± 4% CVCmax; Asc + A-I: 41 ± 3% CVCmax; P < 0.001) but not in Y (Asc: 36 ± 3% CVCmax; Asc + A-I: 40 ± 5% CVCmax; P > 0.05). Combined Asc + A-I resulted in a greater increase in VD than Asc alone in O ( P = 0.001). Acute Asc supplementation increased reflex VD in aged skin. Asc combined with arginase inhibition resulted in a further increase in VD above Asc alone, effectively restoring CVC to the level of young subjects.
