Abstract:
... A new method involving gut microbiota biotransformation, spectrum-effect relationship analysis and metabolomics analysis was developed to study the antitussive and expectorant microbial metabolites of platycosides fraction (MPFs) of Platycodonis Radix. Furthermore, their possible metabolic mechanisms were studied for the first time. The findings showed that the antitussive and expectorant effects ...

Abstract:
... Several polyunsaturated fatty acids are considered to have beneficial health effects, while saturated fatty acids and industrial trans fatty acids (TFAs) are linked to negative health consequences. Given the increased formation of TFAs during heating, many studies already investigated compositional changes in oils after prolonged heating or at extremely high temperatures. In contrast, our aim was ...

Abstract:
... The aim of the study was to compare two sources of tannins on fatty acids (FA) composition in rumen. Treatments were (g tannins/kg diet as-feed-basis) as follows: (1) no supplemental tannin addition (CON), (2) addition of 13 g of oak bark extract (OAK), and (3) 4 g of tannic acid (TAN). The basal diet contained 55:45 forage to concentrate ratio. Net consumption of tannins (g/d) was 4 g for both ta ...

Abstract:
... The purpose of this study was to investigate the effect of variety, ripening degree, and also fermentation process on the bioactive compounds of olives, and on the fatty acid compositions of olive oils. The highest oil content was determined in fermented green olives (70.02% in Gemlik variety; 66.87% in Ayvalık variety). The fermentation process caused a notable reduction in both total phenolic co ...

Abstract:
... BACKGROUND: Unsaturated fatty acids used to form unstable micro‐vesicles, while conjugate linoleic acid (CLA)‐sodium dodecyl sulfate (SDS) can self‐assembly to stable nano‐conjugate linoleic acid vesicles (nano‐CLAVs). Generally, micro‐capsule could geometrically provide higher loading capacity but also generate concerns in construction convenience, sustained release, bioaccessibility and stabilit ...

Abstract:
... The beneficial effects of n-3 LCP (Long Chain PUFA) on human health are widely known. Humans are rather inefficient in synthetizing n-3 LCP, thus, these compounds should be supplemented in the diet. However, most Western human diets have unbalanced n-6/n-3 ratios resulting from eating habits and the fact that fish sources (rich in n-3 LCPs) are not sufficient (worldwide deficit ~ 347,956 t/y) to m ...

Abstract:
... The total phenol and total flavonoid amounts of raw and roasted quinoa grains were measured between 135.63 (control) and 176.75 mgGAE/100 g (15 min) to 332.86 mg/100 g (control) and 421.43 mg/100 g (15 min), respectively. Also, antioxidant activity values of quinoa grain extracts were established between 14.15 mmol/kg (control) and 14.84 mmol/kg (15 min). Although gallic acid contents of quinoa gr ...

Abstract:
... Oils high in linoleic acid are the main sources of polyunsaturated fatty acids in the human diet. The study attempted to increase the oxidative stability of 11 cold-pressed oils with various linoleic acid percentages by adding phenolic acid derivatives (canolol, guaiacol) at concentrations of 20–100 ppm. The oils were characterized by acid, peroxide and anisidine values, diene, triene, and water c ...

Abstract:
... This research evaluates beef burger patties made with meat from animals fed with the addition of 0.0%, 0.5%, 1.0%, and 1.5% lauric acid as a diet supplement. Beef burger patties showed no change (p > .05) in most physicochemical characteristics (centesimal composition, cooking loss, water activity, color parameters), lipid oxidation, and fatty acid (FA) concentrations. The pH, C12:0 and conjugated ...
... Conventional methods for determining phenolics and their bioactive properties are expensive, time-consuming, and laborious. This hinders the quality control of red propolis, recognized for having different types of phenolic constituents with different bioactive properties, for example, its antioxidant properties. In this sense, we present a new application of near and medium infrared spectroscopy ...
... Goji fruits grown in the organic and conventional systems were investigated for phenolic content (TPC), antioxidant activity (AA), carotenoid and ascorbic acid profile, fatty acid composition (FA), and thermal stability. Phenolic extracts and solid samples were analyzed, comparing the use of shaker and ultrasound for Folin-Ciocalteu, Fast Blue BB, and FRAP methods. HPLC and GC-FID were used to det ...
... Ascorbic acid is a multifaceted compound that can perform both antioxidant and pro-oxidant activities in the redox reactions induced by transition metal ions, so its role in nature and especially in the human body is still the subject of debate. In the present study, we have examined the influence of ascorbic acid on lipid peroxidation in a model system that mimics the cell membrane, namely micell ...
... Recent trial studies have found that conjugated linoleic acid (CLA) supplementation beneficially reduces oxidative stress markers but, there is no definitive consensus on this context. The present systematic review and meta-analysis aimed to investigate the effect of CLA supplementation on oxidative stress parameters. We searched PubMed, Web of Science, Scopus, Cochrane Library, and Google Scholar ...
... Enodolichenic fungi (ELF) are considered a promising bio-resource since they produce a variety of novel secondary metabolites with bioactivities. Ultraviolet (UV) radiation in sunlight containing UVA and UVB can cause acute and chronic skin diseases, and the demand for UV protectants in sunscreens has been increasing. Such situations evoke the strong interest of researchers in seeking effective UV ...
... Findings from studies of muscle regeneration can significantly contribute to the treatment of age-related loss of skeletal muscle mass, which may predispose older adults to severe morbidities. We established a human experimental model using excised skeletal muscle tissues from reconstructive surgeries in eight older adults. Muscle samples from each participant were preserved immediately or maintai ...

Abstract:
... Deep‐frying oil featuring total polar compound (TPC) has been found to be unhealthy. However, little information is available regarding the impact of TPC on the lipid digestion behaviour. In this study, three typical edible oils (palm oil, PO; high oleic acid peanut oil, HOA; and high linoleic acid sunflower oil, HLA) were selected to investigate the effect of deep‐frying on the lipid digestion. D ...
... Lipid peroxidation (LPO) plays a key role in many age-related neurodegenerative conditions and other disorders. Light irradiation can initiate LPO through various mechanisms and is of importance in retinal and dermatological pathologies. The introduction of deuterated polyunsaturated fatty acids (D-PUFA) into membrane lipids is a promising approach for protection against LPO. Here, we report the p ...

Abstract:
... The SARS-CoV-2 spike protein is the first contact point between the SARS-CoV-2 virus and host cells and mediates membrane fusion. Recently, a fatty acid binding site was identified in the spike (Toelzer et al. Science 2020). The presence of linoleic acid at this site modulates binding of the spike to the human ACE2 receptor, stabilizing a locked conformation of the protein. Here, dynamical-nonequi ...
