TL;DR: The mutagenicity and the genotoxicity of different concentrations of the Atrazine herbicide were determinated by the micronucleus test and the comet assay, using Oreochromis niloticus as test-system.

TL;DR: Results indicate that methanolic extract of Artemisia annua L. extract contains inhibitors of key metabolic pathways that may be useful in future control of the elm leaf beetle.

TL;DR: In this article, IMI microcrystals were directly encapsulated with nature polysaccharides chitosan (CHI) and sodium alginate (ALG) through layer-by-layer self-assembly.

TL;DR: There is a growing body of literature suggesting that p-gps, and other ABC proteins, are important in regulating pesticide toxicity and represent potential control failure through the development of pesticide resistance, in both agricultural and medical pests.

TL;DR: Results indicated that the increased expression of the carboxylesterase resulted from the increased transcription levels of carboxyleterase mRNA was related to omethoate resistance in cotton aphids.

TL;DR: Collective results demonstrated that exposure of fish to pesticides induced an increase in MDA joined with fluctuated ADS, which may reflect the potential role of these parameters as useful biomarkers for assessment of water pollution.

TL;DR: Results suggest that dimethoate (100 and 200 ppm) and UV-B alone caused heavy damage on pigments and photosynthetic activity of cowpea, leading to the significant inhibition in growth.

TL;DR: Green tea supplementation partially counteracts the toxic effect of fenitrothion on oxidative stress parameters and repairs tissue damage in the liver and kidney, especially when supplemented to 1/60 LD50 intoxicated animals depending on the duration.

TL;DR: The results suggest that catalase activity can be a good diagnostic tool for sodium cyanide toxicity in biomonitoring programme.

TL;DR: In this article, the physiological responses of sugarcane (Saccharum officinarum L.) to oxidative stress induced by methyl viologen (paraquat) were examined with respect to photochemical activity, chlorophyll content, lipid peroxidation and superoxide dismutase (SOD) and ascorbate peroxidase (APX) activities.

TL;DR: It was concluded that tebufenozide selection could resulted in significant cross-resistance of P. xylostella to abamectin and would not recommend for rotational use for resistance management.

TL;DR: It is demonstrated that the yeast expression system can provide necessary redox environment for insect P450s to metabolize xenobiotics and provide important evidence on the role of CYP 9A12 and CYP9A14 in conferring pyrethroid resistance in H. armigera.

TL;DR: In this article, the recommended field dose of metribuzin, butachlor and chlorimuron-ethyl to 10-day-old wheat and maize seedlings differentially reduced shoot fresh and dry weights during the following 16 days.

TL;DR: The short term effect of low dose synthetic pyrethroid and insecticide α-cypermethrin was investigated in selected tissues of male albino Wistar strain rats and affected histopathological changes in the treated animal tissues.

TL;DR: The results showed that methomyl exhibited greater efficacy than did methiocarb against the snails in both techniques, however, higher mortality rates were obtained in the topical application technique than in the poison bait experiments.

TL;DR: The present findings suggest that the in vivo hepatotoxicity associated with benomyl may, in part, result from the hematological index, and antioxidants may provide limited protection againstbenomyl toxicity.

TL;DR: It is suggested that the inhibition of the ATPase by monocrotophos blocked the active transport system of the gill epithelial as well as chloride cells, glomerular and epithelial cells of the tubules and thus altered the osmoregulatory mechanism of the fish.

TL;DR: In this paper, the salt stress ameliorative effect of propiconazole (a triazole group of fungicide cum plant growth regulator) on the NaCl stressed Catharanthus roseus was investigated.

TL;DR: In this paper, the role of α tocopherol and selenium on malathion induced hepatic damage, and antioxidant defense in chicks was investigated, where chicks were divided into three groups.

TL;DR: It is concluded that Bt-maize does not affect the development of the non-target aphid S. avenae and that Cry1Ab toxin quantities in these aphids are nil, suggesting an inconsequential risk for natural enemies of this aphid species.

TL;DR: It can be concluded that, the triadimefon can be used as a potential tool to enhance the antioxidant potential in medicinal plant W. somnifera Dunal plants.

TL;DR: The results showed that EMA had multiple effects on the growth of S. capricornutum under different initial algal densities (IADs), and the initialAlgal density is considered an important factor to influence algal growth and physiological and biochemical responses to EMA.

TL;DR: Results of this study can be explain by a stimulation of glycogenolysis and gluconeogenesis by liver, with a temporarily loss of endocrine functions of pancreas leading to hyperglycemia.

TL;DR: Treatment with CSE significantly protected rat pancreas from injury, thus ameliorating and restoring tissue antioxidant status and also conferring normal glucose tolerance, and CSE supplement amelIORated the biochemical alterations in the pancreatic milieu in DM treated rats.

TL;DR: The silphinenes tested in neurophysiological recordings of central neurons from third instar Drosophila melanogaster larvae reversed the blockage of neuronal firing induced by GABA, but had little effect below 100 μM.

TL;DR: Silver catfish exposed to concentrations of 2,4-D near of CL 50 showed metabolic and histological response to compensate some stress caused by herbicide exposure, suggesting parameters measured can be used as biomarkers to monitor herbicide contaminated water.

TL;DR: In this article, the interaction of 5-Iodouracil with human serum albumin (HSA) was investigated in aqueous solution by fluorescence quenching spectrum in combination with UV absorption spectrum and modeling method.

TL;DR: Results of present study showed that toxicity of organophosphate compound fenthion increases the lipid peroxidation and depresses endogenous antioxidative systems, and leads to muscle injury in organism.

TL;DR: Bioassays performed in order to evaluate the efficacy of a pyrethroid insecticide against a strain possessing a F979S mutation within its para-type sodium channel gene suggests that this amino acid substitution could affect the sodium channel responsivity to pyrethroids.

TL;DR: Efficacy of three prototype termite cellulase inhibitors, cellobioimidazole (CBI), fluoromethylcellobiose (FMCB) and fluorometHylglucose(FMG) is investigated, suggesting potential for these inhibitors as novel termite control agents.
