Inhibitory activities against angiotensin I-converting enzyme (ACE) of enzymatic hydrolysates of porcine skeletal muscle proteins were investigated. Myosin B, myosin, actin, tropomyosin, troponin and water-soluble proteins extracted from pork loin were digested by eight kinds of proteases, including pepsin, α-chymotrypsin, and trypsin. After digestion, hydrolysates produced from all proteins sh...

introduction: decidua as the nearest mother's tissue layer to the fetus which is in direct contact with the embryo has an important role in composing the appropriate microenvironment for protection of allogenic fetus from mother's immune response. in this study the effect of supernatant from culture of decidual cells on dendritic cells regarding the induction of t-cell allogenic proliferation r...

Growing research effort in recent years has focused on the role of 5-methylcytosine (5-MeC) in gene expression. 5-MeC has been implicated in such phenomena as genomic imprinting, maintenance of heterochromatin, and the direct control of gene expression through proteins which bind methylated DNA (1). As interest in 5-MeC has intensified, several new techniques have been developed to find and stu...

This study was carried out to estimate the relevance of biological supplementation in improving economic efficiency anaerobic digestion (AD). Three kinds silages—maize, grass, and igniscum—were initially inoculated with digestate then supplemented one four vaccines containing different bacteria species (APD®, PPT®, JENOR®) or a yeast mold mixture (HAP®). In addition, each plant silage fermented...

One of the most intriguing questions in modern enzymology is whether enzyme dynamics evolved to enhance the catalyzed chemical transformation. In this study, dihydrofolate reductase, a small monomeric protein that catalyzes a single C-H-C transfer, is used as a model system to address this question. Experimental and computational studies have proposed a dynamic network that includes two residue...
