Introduction: Paraoxon (the neurotoxic metabolite of organophosphorus (OP) insecticide, parathion) exerts acute toxicity by inhibition of acetylcholinesterase (AChE), leading to the accumulation of acetylcholine in cholinergic synapses and hence overstimulation of the cholinergic system. Since, reports on changes in the level of γ- amino butyric acid (GABA) during OP-induced convulsion have bee...

A model has been used to simulate potassium (K) uptake by wheat in a pot culture experiment. Three soils from India, namely Alfisol, Inceptisol and Vertisol, were differentially K exhausted by Sudan grass (Surghum vulgare var. Sudanensis) for a period of 280 days and were used to simulate potassium uptake by wheat (Triticum aestivum) and also to predict the amounts of K released or fixed during...

ABSTRACT- The effects of iron (Fe) and zinc (Zn) treatments on the growth and nutrient composition of chickpea were studied in a greenhouse experiment arranged in a completely randomized design. While the application of Fe decreased mean shoot dry weight of chickpea, that of Zn had no significant effect on chickpea shoot dry weight. Increasing Fe levels drastically decreased Mn concentration an...

a 3-km reach of the luján river was studied by establishing 6 sampling stations, which were from 300 to 500 m apart. the first station was the control reading for river nutrients and particulate material. the second station measured the continuous effluent from a wastewater treatment plant flow of the city of luján and was, therefore, considered a continuous addition point of nutrients. the oth...

this study was carried out in order to evaluate the changes of nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of leonardite and foliar application of n and k. the experiment was conducted in gorgan university of agricultural sciences and natural resources during 2013- 2014. the experiment was laid out a using split-plot arrangement based ...

wheat (triticum aestivum l.) was grown in earthen pots containing soil of balkasar soil series (sandy loam) in green house at the department of soil science and swc, pir mehr ali shah arid agriculture university, rawalpindi during rabi season, 2007. the crop was treated with two levels of phosphorus (40 and 80 kg p ha-1 ) in the form of ssp, tsp, np and dap. a basal doze of 100 kg n and 60 kg k...

this study investigates the effect of four types of oral corrective feedback, namely, explicit elicitation, implicit elicitation, explicit recast and implicit recast on the most commonly mispronounced phonological features among iranian efl learners through immediate uptake and retention. five classes were randomly categorized into four experimental groups and one control group, each with 18 in...

introduction: the aim of this study was to investigate the effect of methimazole on technetium-99m reabsorbing by thyroid gland , it may be possible to perform thyroid scan when the patients are on the methimazole, this can be time saving and decrease the adverse effects of discontinuing methimazole. patients and methods: among all the patients with hyperthyroidism who referred to nuclear medic...

abstract the plants which can be used to clean up the soil of heavy metals contamination are named phytoremedation. phytoremediation has received increasing attention because of its low environmental impact and cost-effectiveness. but, it is slowly process and needs long time. in such reson, chelating agents have been proposed to improve the efficiency of phytoextraction by increasing solubilit...
