A previously unknown metabolite necessary for growth of T strains of Mycoplasma in artificial culture media has been identified as urea. The source of this metabolite was the mammalian plasma or serum enrichment of the culture medium. Normal horse serum was the most satisfactory native protein enrichment for cultivation of T strains of mycoplasma, and it is believed that its superior performanc...

Stomach infection with Helicobacter pylori (H. pylori) causes severe gastroduodenal diseases in a large number of patients worldwide. The H. pylori infection breaks up in early childhood, persists lifelong if not treated, and is associated with chronic gastritis and an increased risk of peptic ulcers and gastric cancer. In recent years, the problem of drug-resistant strains has become a global ...

Ureases are amidohydrolases that catalyze the hydrolysis of urea to ammonia and carbamate. In addition enzymatic function, ureases have fungitoxic insecticidal which independent their catalytic activity. Soy (Glycine max) has two main urease isoforms: ubiquitous embryo-specific, latter is present in beans. view potential applications ureases, this work aimed extract, purify, characterize struct...

In this study, the inhibitory effects of extracts prepared from oleaster seeds on antioxidant activity, anti-urease and anti-collagenase enzyme activities, which have an important area in health, were investigated. For purpose, aqueous methanolic these enzymes analyzed by spectrophotometric measurements. The effect was evaluated vitro method. Only extract found to show both activity. It determi...

Objective: Natural ingredients derived from plants (especially edible ones) continue to be investigated for understanding whether they have therapeutic/preventive effects on certain ailments, such as cancer and gastrointestinal disorders. The main goal of the current work is investigate inhibitory potential Eremurus spectabilis M. Bieb. extracts histone deacetylase (HDAC), xanthine oxidase (XO)...
