A bacterial strain Pseudomonas sp. a3 capable of degrading nitrobenzene, phenol, aniline, and other aromatics was isolated and characterized. When nitrobenzene was degraded, the release of NH(4) (+) was detected, but not of NO(2) (-). This result implied that nitrobenzene might have a partial reductive metabolic pathway in strain a3. However, aniline appeared as one of the metabolites during th...

the purpose of this study is to investigate the accuracy of predictions of aniline removal efficiency in a moving bed biofilm reactor (mbbr) by various methods, namely by rbf, anfis, and fuzzy regression analysis. the reactor was operated in an aerobic batch and was filled by light expanded clay aggregate (leca) as a carrier for the treatment of aniline synthetic wastewater. exploratory data an...

objective: interaction between genetic and environmental factors is considered as major factors in schizophrenia (scz). it has been shown that dopaminergic and noradrenergic neurotransmission dysfunction play an essential role in the scz pathogenesis. this study aimed to find the impact of functional 19-bp insertion/deletion (ins/del) polymorphism in dopamine beta-hydroxylase (dbh) gene on scz ...

The steroidogenic lesion produced in Leydig cells by gonadotropin stimulation has been attributed to an inhibitory effect of estrogen on 17a-hydroxylase and 17,20-desmolase activity, with impaired conversion of progesterone to androgens. In animals treated with doses of human chorionic gonadotropin (hCG) or gonadotropin-releasing hormone (GnRH) that caused the decrease in desmolase activity, ad...

this study aims at exploring an effective route in the in situ graft polymerization of aniline from fe3o4 nanoparticles. to this goal, fe3o4 magnetic nanoparticles were prepared by coprecipitation method using ammonia solution as the precipitating agent, and were characterized by fourier transform infrared (ft-ir) spectroscopy, x-ray diffraction (xrd) and transmission electron microscopy (tem)....

Electrochemical polymerization of aniline is one of the most promising methods to prepare polyaniline (PANI) materials. However, during this process, the electrolyte solution must be replaced after electropolymerization of a certain time because of the generation and the accumulation of the by-products, which have significant effects on the morphology, purity and properties of PANI products. Tr...

Mutagenic/carcinogenic 9-(4'-aminophenyl)-9H-pyrido[3,4-b]indole [aminophenylnorharman (APNH)] is formed from norharman and aniline in the presence of cytochrome P450 3A4/1A2. Because both precursors are widely distributed in the environment, human exposure is unavoidable. To clarify APNH formation in the human body, amounts of the compound in 24-h human urine collected from smokers and nonsmok...

In this study, montmorillonite clay was used as the adsorbent for the removal of Aniline Blue dye, from aqueous solution by the batch adsorption technique under different conditions. The maximum removal of aniline blue dye for initial dye concentration 20 mg/L was more than 95% at optimum conditions (pH=4.5, contact time=30 min, and adsorbent dosage=2 g/L). The data of this study were fitted wi...

parkinson’s disease (pd) is a rather common movement disorder as a result of the degeneration of dopaminergic neurons within the substantianigra. current treatments for pd afford symptomatic relief with no prevention of disease progression. due to the neuroprotective and anti-apoptotic potential of the isoquinoline alkaloid berberine (bbr), this study was conducted to assess whether bbr pretrea...
