Hypertension IS accompanied by architectural changes m the kidney, heart, and vessels that are often maladaptlve and can eventually contribute to end-organ disease such as renal failure, heart failure, and coronary disease Nitric oxide, an endogenous vasodllator and antlthrombotlc agent synthesized m the endothehum by a constltutlve mtnc oxide synthase, mhlblts growth-related responses to injur...

After growth in the absence of nitrogenous oxides under anaerobic phototrophic conditions, several strains of Rhodopseudomonas capsulata were shown to possess a nitrous oxide reductase activity. The enzyme responsible for this activity had a periplasmic location and resembled a nitrous oxide reductase purified from Pseudomonas perfectomarinus. Electron flow to nitrous oxide reductase was couple...

introduction: accumulating evidences indicated that during increasing of the animals' age, the number and the functional properties of hematopoietic stem cells (hscs) become altered because of a gradual decrease in replication potential.  the efficient factors in this process are dna damaging, reduced telomerase activity, shortening of telomeres and oxidative stresses. for overcoming these fact...

gas diffusion electrode was used for providing better conditions in fuel cell systems for oxygen reduction reaction (orr). because the slow kinetics of the oxygen reduction reaction at the proton exchange membrane fuel cell cathode restricts fuel cell efficiency. to this end, researchers have used platinum-coated carbon. in the present study, due to the reduction of carbon corrosion, zinc oxide...

AIMS To assess the potential bactericidal activity of amine oxide (C10-C16-alkyldimethyl N-oxides) against Streptococcus mutans grown as planktonic suspension and as biofilm on hydroxyapatite discs, and its ability to control acidification of the media. METHODS Amine oxide bacteriostasis was investigated using the Bioscreen C Microbiological Growth Analyser, while a standard suspension test w...
