Article Abstract
Enzymatic hydrolysis of almond gum generates low molecular weight oligosaccharides (OAG) with a yield of 33.5%. The generated oligosaccharides were purified and identified. OAG analyses show that the most prominent residues were galactose and arabinose with traces of xylose, rhamnose, glucose and mannose. The glycosyl linkage positions were analyzed using gas chromatography-mass spectrometry showing a main chain composed of galactose units [ → 3)-Gal-(1 → ] branched mainly with arabinose residues [Ara-(1 → ]. The antioxidant and antimicrobial activities of OAG were investigated. As regards the in vitro antioxidant activities, the OAG showed a high total antioxidant activity (347 μg ascorbic acid equivalent/mL), an important DPPH (1,1-diphenyl-2-picrylhydrazyl) scavenging activity (IC50 = 0.64 mg/mL) and a high reducing capacity (RP0.5AU = 3.6 mg/mL). Furthermore, OAG had a high antimicrobial activity against Salmonella thyphimirium, Bacillus cereus, Actinomycetes sp, Klebsiella pneumoniae, Escherichia coli, Alternaria alternate and Candidat albicans. Finally, OAG efficiency was tested using 0.5%; 0.75% and 1% concentrations in beef meat preservation. Microbial growth and lipid oxidation were monitored during 9 days at 4 °C. The results showed significant inhibitions (p < 0.05) of lipid oxidation and microbial growth in ground beef meat containing OAG.
Introduction: Maternal nutrition during pregnancy critically influences offspring development and immune function. One-carbon metabolites (OCM) are epigenetic modifiers that may modulate antimicrobial peptide (AMP) expression, which is vital for innate immunity. This study investigated the effects of maternal nutrient restriction and OCM supplementation on mRNA expression of AMP in fetal and maternal lung, mammary gland, and small intestine of beef cattle.
Background: Fat traits in cattle are considered important due to their contribution to beef eating quality and carcass economic value. Discovering the genes controlling fat traits in cattle will enable better selection of these traits, but identifying these genes in individual experiments has proven difficult. Compared to individual experiments, meta-analyses allow greater statistical power for detecting quantitative trait loci and identifying genes that influence single and multiple economically important fat traits.
Background: Current evidence on the role of macro- and micronutrients in the aetiopathogenesis of endometriosis is controversial.
Objectives: In this systematic review, we aimed to investigate the effect of macronutrients, dairy products, fruits, and vegetables on the occurrence and progression of endometriosis.
Materials And Methods: A systematic literature review of eligible articles retrieved from medical databases, including PubMed, Cochrane, and Academic Search, was performed from inception to May 2023.
The fat content of yak meat is significantly correlated with the meat quality, and an appropriate fat content helps to improve the texture of the meat. The involvement of miR-10a in regulating the differentiation and proliferation of various cell types has been reported. Therefore, in this study, the effects of miR-10a on lipid droplet accumulation were investigated by transfection of yak adipocyte precursors with an miR-10a inhibitor, followed by Oil Red O, BODIPY, EdU staining, and cell cycle analysis of the transfected and control cells.
Background: Epidemiological evidence on meat consumption and liver cancer risk is limited and inconclusive; moreover, no prospective study has been conducted to investigate this association in China. Hence, we performed this study to examine the associations of red meat, poultry, and fish consumption with the risk of liver cancer in a Chinese population.
Methods: A total of 510,048 Chinese adults aged 30-79 years were included, and were followed up through December 31, 2016.
