In this communication we draw attention on serious flaws that plague recently reported antioxidant properties of atorvastatin (ATV) in methanol. First and foremost, emphasize the O-H bond dissociation energies (BDE) about 400 kcal/mol previously are completely wrong. Further, present results refuting previous claim proton affinity (PA) ATV is smaller than ascorbic acid. That unfounded relies in...

The anticorrosion potency of Sabic mild steel (MS) in 0.5 M H2SO4 solution was enhanced by three synthetic non-ionic surfactants (NI Surf.) containing pyridine and pyrimidine derivatives. These compounds are safe, environmentally friendly, harmless to human health. Chemical electrochemical measurements were used compute the corrosion parameters. efficacy increases with increasing concentration ...

We have studied hydrogen-passivated amorphous carbon nanostructures with semiempirical molecular orbital theory in order to provide an understanding of the factors that affect their electronic properties. Amorphous structures were first constructed using periodic calculations in a melt/quench protocol. Pure periodic amorphous carbon structures and their counterparts doped with nitrogen and/or o...

background and objective: alzheimer’s disease (ad) is a multifactorial disease with debilitating consequences and few therapeutic strategies exist for it. with regard to antioxidant capacity and anti-β-amyloid polymerization potential of ellagic acid, this study was conducted to evaluate the effect of this substance on enhanced acetylcholinesterase reactivity in an experimental model of alzheim...

background and objectives: brucella melitensis infection is still a major health problem for human and cattle in developing countries and the middle east. materials and methods: in this study, in order to screen immunogenic candidate antigens for the development of a brucella subunit vaccine, a cytoplasmic protein (dnak) and an outer membrane protein (omp31) of b. melitensis were cloned, expres...

background: several studies reported the clinical features of ige-mediated hypersensitivity after ingestion of melon. melon allergy is a common ige-mediated fruit allergy in iran. this prompted us to investigate immunochemical and molecular properties of the major allergen in melon fruit, to compare the ige-binding capacity of the natural protein with the recombinant allergen, and to determine ...
