Abstract:

Proteins, peptides and amino acids (AAs) that bypass upper gastrointestinal (GI) digestion can be fermented in the colonic regions. This could lead to microbial production of health promoting short-chain fatty acids (SCFAs). Nitrogenous compounds can also be fermented to generate potentially harmful branched chain fatty acids (BCFAs). As collagen hydrolysate (CH) supplements contain a high peptide content, we evaluated whether peptides that undergo intestinal CH digestion and microbial fermentation can generate SCFAs and BCFAs. Two bovine-sourced CH formulations (CH-GL and CH-OPT) underwent di

Abstract:

The habit of eating wild plants in Europe is often associated with times of famine; an example of such is the nectar of Cytinus hypocistis (L.) L., a parasitic plant. To the authors’ best knowledge, there are no studies on its nutritional and chemical composition; thus, the whole C. hypocistis (L.) L. subsp. macranthus Wettst. plant (CH) and its nectar (NCH) were nutritionally and chemically characterized. The proximate composition of CH and NCH were very similar in terms of energy, ash, and carbohydrate content. Protein and fat were approximately 2-fold higher in NCH, and crude fiber was 4.6-

Abstract:

Boron isosteres [ CH 3- CO - BH - CH(R) - CONHCH 3; R = CH 3, CH 2 OH , CH 2 SH ] of natural amino acids have been designed as inhibitors of serine protease based on boron's ability to mimic the transition state of the normal enzyme catalyzed reaction. The conformation and electronic properties of these isosteres have been determined by ab initio calculations at the HF/6-31G** level of theory. The global minimum energy structures of the boron isosteres (which are all identical) and the natural amino acids are radically different. Interestingly, the boron isosteres have favorable conformations

Abstract:

Osteoarthritis (OA), the most common form of arthritis, is associated with metabolic diseases and gut microbiome dysbiosis. OA patients often take supplements of collagen hydrolysates (CHs) with a high peptide content. Following digestion, some peptides escape absorption to induce prebiotic effects via their colonic fermentation to generate short-chain fatty acids (SCFAs), branched-chain fatty acids (BCFAs) and colonic gases (NH4 and H2S). The capacity of CHs to generate microbial metabolites is unknown. Proteomic analysis of two CHs (CH-GL and CH-OPT) demonstrated different native peptide pro

Abstract:

Aberdeen Angus (AA), Charolais (CH), Simmental (SI), and Hereford (HE) bulls were used in two fattening experiments with the objective of determining breed differences in chemical composition, sensory characteristics, and fatty acid profile of m. longissimus thoracis et lumborum. The target slaughter live weights were set at 550 kg for earlier maturing breeds AA and HE and 630 kg for later maturing breeds CH and SI. Intramuscular lipid contents were higher in AA and HE (P &lt; 0.05) than in CH and SI, but cholesterol contents were similar among the breed groups. The highest content of dry

Abstract:

In this work, the proton transfer between carbon acids and amine bases was investigated using computational methods. The effect of substitutions on the interaction between 1-nitro-1-(4-nitrophenyl) alkanes (with R = H , CH 3) and 1-5-7-triazabicyclo[4,4,0]dec-5-ene) (TBD) was investigated. The solvent effects on proton transfer reaction between 1-nitro-1-(4-nitrophenyl) alkanes (in which R = H , CH 3) and TBD have been calculated in acetonitrile and water solvents. The products of proton transfer reactions between C -acids and 7-methyl-1-5-7-triazabicyclo[4,4,0]dec-5-ene (MTBD) were dissociate

Abstract:

Gender and dietary fatty acids are involved in the regulation of lipid metabolism, disturbances of which can lead to pathologies such as metabolic syndrome or CVD. Possible interactions between these factors were investigated in male and female hamsters fed diets rich in either saturated fatty acids (‘butter’ diet) or in α-linolenic acid (‘linseed oil’ diet). Gender effect predominated over the diet effect on cholesterol (CH) metabolism; compared to males, females exhibited lower concentrations of plasma total CH (−20%,P<0·001), LDL-CH (−40%,P<0·001) and HDL-CH (−16%,P<0·001), togethe

The aim of this study was to investigate the effect of two species of the microalgae on the milk yield, the basic composition and the fatty acid profile of goat milk, with focus on n‑3 fatty acids. Forty‑five White short‑haired goats were randomly allocated to three groups; the control group (C) with no supplementation microalgae to the diet. The first experimental group (Ch) was supplemented with Chlorella vulgaris and second experimental group (J) has been supplemented with Japonochytrium sp. The Japonochytrium supplementation negatively affected milk yield, but the amount of milk fat (+0.1

Abstract:

Citrus honey (CH) is rich in nutrients that have a wide variety of biological functions, such as antibacterial, anti–inflammatory, and antioxidant activities, and which demonstrate therapeutic properties, such as anti–cancer and wound–healing abilities. However, the effects of CH on alcohol–related liver disease (ALD) and the intestinal microbiota remain unknown. This study aimed to determine the alleviating effects of CH on ALD and its regulatory effects on the gut microbiota in mice. In total, 26 metabolites were identified and quantified in CH, and the results suggested that the primary met

Abstract:

Abstract The chimpanzee (Ch) E complement receptor type 1 (CR177) appears to be an alternatively spliced product of the Ch CR1 gene transcript. Its cDNA-derived amino acid sequence contains complement protein-repeating modules (CP) 1-6, 28, 29, and 30 in tandem and is 98.8% homologous to the corresponding regions of human (Hu) CR1. It differs from the C4b binding site of Hu CR1 only by two amino acids, Tyr for Ser37 in CP 1 and Asp for Gly79 in CP 2. However, in addition to binding C4b, Ch E binds C3b. As homologous substitution of one of these amino acids (Tyr for Ser37) was previously shown
