Quantification of skin penetration of antioxidants of varying lipophilicity

Antioxidants play a vital role in protecting the skin from environmental distress. As the skin is constantly exposed to harmful UV radiation, endogenous antioxidants present in the superficial layers of the skin neutralize reactive oxygen species. Over time, antioxidants become depleted and loss their protective effect on the skin. Therefore, supplementing skin with topical antioxidant can help replenish this loss and fight the oxidative stress. The objective of this study was to deliver antioxidants topically and quantify the amount permeated in the stratum corneum and underlying skin. Polyphenols (catechin, resveratrol and curcumin) and vitamin (retinol) with various lipophilic properties were delivered via porcine ear skin, using propylene glycol as a vehicle. The amount in the stratum corneum and underlying skin was quantified using tape stripping and skin extraction methods, respectively, and samples were analysed via HPLC. All four antioxidants permeated into the skin from the propylene glycol vehicle. The order of the amount of antioxidant in the stratum corneum was catechin > resveratrol~ retinol> curcumin, whereas that in the underlying skin was retinol > catechin~ resveratrol~ curcumin. Of the total amount of polyphenols in the skin, approximately 90% was retained in the stratum corneum whereas 10% was quantified in the underlying skin. In contrast, 10% of retinol was retained in the stratum corneum whereas 90% permeated in the underlying skin. Polyphenols (catechin, resveratrol and curcumin) showed high concentration in the stratum corneum whereas retinol showed high accumulation in the underlying layers of the skin.     

Influence of different methods of cooking of hunchback salmon on contents of polyunsaturatedfatty acids

Composition and contents of fatty acids in hunchback, fresh, boiled, fried, roasted and boiled in a small amount of water were determined. It was found, that absolute contents of essential polyunsaturated fatty acids--eicosapentaenoic (EPA) and docosahexaenoic (DHA) decreased significantly only in the process of frying. Sum ratio of omega3/omega6 acids was dietetically more favorable in the roasted and fried fish.     

预处理对六种黄酒酿造原料酿造特性的研究

为探究不同黄酒酿造原料的酿造特性,以红谷、张杂谷、圆糯米、黍米、金米、粳大米等六种谷物为原料进行浸泡和蒸饭实验,监测浸泡过程中不同原料质构和色泽的动态变化;比较了浸泡后六种米浆水的有机酸和氨基酸组成;并对蒸饭中挥发性风味物质的含量进行分析。结果表明,浸泡过程中六种谷物的颜色和质构参数存在显著差异（P＜0.05）。红谷米浆水的总氨基酸含量最高（976.49 mg/L）,乙酸、酒石酸和柠檬酸含量显著高于其他谷物米浆水的相应含量（P＜0.05）。六种谷物蒸饭样品中共检出165种挥发性成分,其中红谷蒸饭中酸类（11.75 μg/100 g）和酚类含量（10.54 μg/100 g）远高于其他谷物。综上所述,红谷米浆水中氨基酸含量以及蒸米中酸类香气成分较高,这有利于发酵醪的进一步微生物发酵。

Mechanism of Prevention of Aggregation of Proteins: A Case Study of Aggregation of α-Globulin in Glycerol

The precipitation of proteins due to the changes in pH has been a major limiting factor in their utility especially when the precipitation is concurrent with irreversible aggregation. In the present study, an attempt is made to see the effect of glycerol on the pH-induced aggregation of α- globulin which is the major protein fraction (11S) from Sesame (Sesamum indicum L.) seeds. A second order polynomial relation existed between the cosolvent concentration and precipitation which was prevented in presence of the cosolvent. Similarly, there was a second order polynomial relation between 8-anilino 1-naphthalene sulfonic acid (ANS) binding of the protein (as indicated by fluorescence emission at 466 nm) and the cosolvent concentration. The relative precipitation in presence of glycerol is however linearly proportional to the changes in surface hydrophobicity as seen by behavior of ANS with the protein in presence of the cosolvent. A possible role of the cosolvents in prevention of aggregation due to hydrophobicity of the protein is envisaged and the relation between the different parameters is discussed.     

Substrate and parasubstrate regulation of physiological processes at various levels of the organization of living systems as illustrated by examples of the regulation of appetite, of the specific dynamic action of food and of the inhibition of processes of absorption]

It was demonstrated that in the organism of higher animals the adaptation regulation of food uptake and nutrient absorption and transport comprises, in addition to the classic mechanisms of substrate regulation, specialized non-substrate and parasubstrate mechanisms which control the uptake of food and other substrates at all three levels (organosystemic, organic and cellular). As to the organosystemic level, it was observed in duodenectomized rats that appetite inhibition is produced not only by a stimulation of the receptors and by an increase in the concentration of the food substrates and of the metabolites in the blood, but also by one of the intestinal appetite-inhibiting hormones, arenterin. As to the organic level, it was evidenced that the enzymatic and transport functions of the small intestine and the numerical composition of the enterocyte population in the different segments are determined by the substrate load on the respective areas of the small intestine as well as by the blood and chyme-mediated intersegmental reactions in the small intestine. As to the tissular and cellular levels, the possibility of a regulation of the enzymatic and transport systems of the microvilli by means of substrates contained in the mucous membrane of the small intestine and endogenous substances (permein and antipermein) was evinced.     

Studies of bioavailability of different food sources of selenium in experiment

The selenium bioavailability in selenium enriched Spirulina (Arthrospira platensis), phycocyanin containing (Se-PC) protein isolate, separated from this micro algae and in sodium selenite was studied and compared in rats. The daily dose of selenium per one animal was 5 microgram in all experimental groups. The average selenium levels in blood serum and liver of animals that received sodium selenite during 14 days were the highest. The average selenium level in blood serum of animals fed with selenium enriched Spirulina platensis after 14 days of receiving was the same with the control group, but the average concentration of selenium in their liver was rather high and close to this parameter of sodium selenite animal group. The animals which were fed with Se-PC showed better results. Their average selenium level in blood serum was higher than in Spirulina group, but lower than in sodium selenite group. The average concentration of selenium in the liver of these animals was the same with sodium selenite animal group. As regards to animals that were fed with selenium enriched Spirulina, Se-PC and sodium selenite for 21 days, the average selenium levels ratio in their blood serum and liver was higher than in control group, but these results were not significantly different among each other. The concentrations of selenium in seminal glands in all groups of animals including control group both after 14 and 21 days feeding were close to each other.
