OBJECTIVE The aim of this study was to evaluate the antimycobacterial activity of the essential oil (EO) of Mutellina purpurea L. and its main constituents against the M. tuberculosis H37Ra strain. MATERIALS AND METHODS The M. purpurea EO was obtained by hydrodistillation, while its main constituents were purchased. The minimal inhibitory concentration values were determined by the log2 dilut...

iron oxide is an important biological agent that has a key role in medical processes; however, the mechanism whereby it provides iron for human and animal cells and its biological uses remains unclear. we aimed to evaluate the effects of oral iron oxide on serum iron status and compare the results with those of iron sulfate as a reference salt. fifteen adult rabbits were divided into 3 groups o...

objective: vanillosmopsis arborea baker (asteraceae) has high economic value from chapada to araripe and its bark essential oil is a potential source of alpha-bisabolol. the present study aimed to elucidate the antinociceptive and antipruritic properties of the essential oil of v. arborea baker (eova) in mice. materials and methods: the antinociceptive activity was assessed using the capsaicin,...

The abrasion is a significant issue, especially in machining of rigid steels. A functional and suitable approach for enhancing the heat transfer from machining area is using an intermediate fluid with higher heat transfer potential instead of common fluids. The objective of this experimental study is to discuss production, stability and thermal conductivity examination of water/graphene oxide n...

Herein, graphene oxide is produced by electrochemical oxidation method from graphite rod to examine its hydrogen peroxide sensing ability. The electrochemically produced graphene oxide is characterized by SEM and XRD. A few layers of Graphene Oxide(GO) sheets and corrugations in graphene sheets appeared intensely crumpled and folded into a typical wrinkled structure after electrochemical oxidat...

n-oxidation of 1,4-dihydro-2,6-dimethyl-1- phenyliminopyridine (7) with several peracids was attempted. the main compound obtained was l-phenyl- 2,6-dimethyl-4-pyridone (8), instead of the expected n-oxide (2). the reaction of phenylhydroxylamine with dimthylrnethoxypyroxonium perchlorate, however, successfully gave the n-oxide (3), which belongs to a class of nitrones in which the diazomethine...
