The rapid evolution of bacteria is crucial to their survival and is caused by exchange, transfer, and uptake of DNA, among other things. Conjugation is one of the main mechanisms by which bacteria share their DNA, and it is thought to be controlled by varied bacterial immune systems. Contradictory results about restriction-modification systems based on phenotypic studies have been presented as ...

Cartilage destruction in the arthritides is thought to be mediated by two main enzyme families: the matrix metalloproteinases (MMPs) are responsible for cartilage collagen breakdown, and enzymes from the ADAMTS (a disintegrin and metalloproteinase domain with thrombospondin motifs) family mediate cartilage aggrecan loss. Many genes subject to transcriptional control are regulated, at least in p...

raspberry waste, obtained from two cultivars, meeker (erm) and willamette (erw) was subjected to evaluation antioxidants and antitumour activities as a potential source of phenolics. some phenolic acids and flavonoids were identified and quantified by hplc. antioxidant activity was tested by measuring ability to scavenge dpph• and •oh by esr spectroscopy. ic50dpph• varied from 0.67 for erm to 0...

thyrotoxicosis is a condition in which tissues are stimulated by increased secretion of thyroid hormone. the most common cause is diffuse toxic goiter and toxic multi-nodular goiter. for more reviews on this disease, the effects of hyperthyroidism on liver enzyme levels were studied. a total of 30 adult male wistar rats weighing about 190 g were purchased from the pasteur institute of iran. in ...

The aim of this study is to examine the differences in COVID-19 risk perception university students, depending on their food consumption (proinflammatory diet and non-proinflammatory diet). A total 513 students aged between 16 42 years (PDG: mean 20.26, standard deviation 3.07; NPDG: 21.78, 4.12) were interviewed via an online questionnaire. subjects divided into two groups: a proinflammatory g...

the genus fusarium is a species rich genus. different media are required to study themorphological characters and classify different species, a time consuming technique. in this study pecticzymograms were used to identify species and form species of fusarium isolates. fusarium isolates (318) wereobtained from different areas and hosts in isfahan province, iran. isolates were identified to speci...
