a field experiment was conducted to evaluate the effect of varying doses of haloxifhope-r-methyl ester herbicide on grass weeds grown at various stages in 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried out as split split plot based on randomized complete block design with three replicates. treatments were haloxifhope-r-methyl ester ...

the fruit of melia azedarach l. (meliaceae) was extracted with hexane, and its fatty acids methyl ester was analyzed using gc/ms. thirteen components representing 85.1% of the total extract were identified. the major components identified were methyl palmitate (18.8%), methyl linolenate (16.1%) and methyl linoleate (9.8%). the fruits’ extract had a lc50 of 5.5 ppm against the larvae of anophles...

Recent reports have indicated the potential usefulness of anticocaine catalytic monoclonal antibodies in reducing cocaine's toxic and reinforcing effects by altering its pharmacokinetics to favor increased metabolism to the systemically inert products ecgonine methylester and benzoic acid. The present study was designed to further these findings by evaluating the hypothesis that administration ...

BACKGROUND Sweat testing is a noninvasive technique for monitoring drug exposure in treatment, criminal justice, and employment settings. METHODS We evaluated cocaine excretion in 9 participants' sweat after they received 3 low doses (75 mg/70 kg) of cocaine HCl subcutaneously within 1 week and, 3 weeks later, 3 high doses (150 mg/70 kg). Six additional participants completed portions of the ...

The ultrasound-assisted (UA) soybean oil methanolysis using KOH as a catalyst was studied at different reaction conditions in a microreactor. Box–Behnken experimental design, with three variables, was performed and the effects of three reaction variables i.e. reaction temperature, catalyst concentration and the methanol-to-oil molar ratio on fatty acid methyl ester (FAME) yield were evaluated b...

The purpose of the current study is to determine whether sex differences in metabolism of cocaine (COC) exist that could contribute to the greater behavioral sensitivity of females to COC administration. To investigate this question, concentrations of COC and its two principle metabolites benzoylecgonine (BE) and ecgonine methyl ester (EME) were measured by gas chromatography/mass spectroscopy ...
