The aim of the study is individual qualitively and quantitatively identification of fatty acids in Pkatsiteli grape seed oil, Phellodendron lavallei oil and Amaranthus seed oil and prediction of its biological activity. Using high-effective liquid chromatogramphy fatty acids were franctionated. Their relative concentrations are expressed as percentages of the total fatty acid component. Identification of the fatty acids consituents is based on comparison of their retention time with that of known standards. The predominant fatty acids in the oils were palmitic, oleic and stearic acids. The investigation demonstrated that fatty acids composition takes marked part in lipid metabolism of biological necessary components. The most interesting result of the investigation was the detection of unusual for the essentain oil begenic acid.

Fecal microbiota transplantation (FMT) could significantly alter the recipient's gut bacteria composition and attenuate obesity and obesity-related metabolic syndromes. DL-norvaline is a nonproteinogenic amino acid and possesses anti-obesity potential. However, the specific mechanisms by which gut microbiota might mediate beneficial effects of DL-norvaline have not been completely elucidated.

Background And Aims: Chronic fatigue is common in patients with inflammatory bowel disease (IBD). The gut microbiota, specifically, microbial diversity and butyrate-producing bacteria have been linked to the fatigue pathogenesis. High-dose oral thiamine reduces fatigue, potentially through gut microbiota modification.

This study provides a comprehensive investigation of antimicrobial additives (ZnO/AgNPs and SiO/AgNPs) on the properties of biodegradable ternary blends composed of poly(hydroxybutyrate) (PHB), poly(lactic acid) (PLA), and polycaprolactone (PCL) by examining the morphology, thermal stability, crystallinity index, and cell viability of these blends. Overall, transmission electron microscopy (TEM) analysis revealed that AgNPs and SiO exhibited comparable sizes, whereas ZnO was significantly larger, which influences their release profiles and interactions with the blends. The addition of antimicrobials influences the rheology of the blends, acting as compatibilizers by reducing the intermolecular forces between biopolymers.

Background: The objective of this study was to evaluate the effects of dietary fatty acids (FA) saturation and lysophospholipids supplementation on growth, meat quality, oxidative stability, FA profiles, and lipid metabolism of finishing beef bulls. Thirty-two Angus bulls (initial body weight: 623 ± 22.6 kg; 21 ± 0.

Background: Cows that develop metritis experience dysbiosis of their uterine microbiome, where opportunistic pathogens overtake uterine commensals. An effective immune response is critical for maintaining uterine health. Nonetheless, periparturient cows experience immune dysregulation, which seems to be intensified by prepartum over-condition.
