Evaluation of acute toxicity of triazophos and deltamethrin and their inhibitory effect on AChE activity in Channa punctatus
Publication date: 2018Source: Toxicology Reports, Volume 5Author(s): Shikha Singh, Rishikesh K. Tiwari, Ravi S. PandeyAbstractPesticides are applied to control the pests indoor and outdoor; however, their remarkable amount reaches to the aquatic system through various routes like run-off, leaching, spray-drift, effluent from factories. These are reported to have negative metabolic impact on different non-target aquatic organisms like fishes. Thus, present study is aimed to evaluate the acute toxicity of two groups of pesticides, organophosphate and pyrethroid, namely triazophos and deltamethrin, respectively. The test was conducted for 96 h period in a freshwater teleost, Channa punctatus. The LC50 values for triazophos and deltamethrin after 96 h treatment was found to be 0.069 mg/L and 7.33 μg/L. The deltamethrin was found to be about ten times more toxic than triazophos to the fish. In treated fish, alterations in various behavioural patterns were observed with increasing concentrations of both the pesticides as compared to control. Further, tissue specific as well as dose dependent inhibition in the acetylcholinesterase (AChE, EC 18.104.22.168) activity was found in brain, muscle and gills in Channa punctatus exposed to both the insecticides. However, the effect was more pronounced in triazophos treated fishes than the deltamethrin. A futuristic approach on biochemical and molecular studies may throw light on the mechanism of action of these pesticides.Graphical abst...
Abstract OBJECTIVE: Using a feasibility analysis and matched subgroup analysis, this study investigated the implementation/safety/outcomes of a stroke recovery program (SRP) integrating modified cardiac rehabilitation for stroke survivors. DESIGN: This prospective cohort study of 783 stroke survivors were discharged from an inpatient rehabilitation facility to an outpatient setting; 136 SRP-participants completed a feasibility study and received the SRP including modified cardiac rehabilitation, 473 chose standard of care rehabilitation (nonparticipants), and a group (n = 174) were excluded. The feasibility s...

ConclusionsThis case series demonstrates that the use of a high frequency jet ventilator for cardiac MRI was feasible, safe, providing good quality cardiac imaging and avoiding anesthesia personnel to be inside the hazardous environment of MRI room. Future studies are needed to confirm its safety and efficiency in pediatric patients.ResumoJustificativa e objetivosA ressonância magnética (RM) cardíaca é uma técnica utilizada na avaliação de crianças com cardiopatias congênitas. A anestesia geral garante imobilidade, especialmente em pacientes não cooperador...
This article focuses on the functional features of positive-pressure ventilators, the modes of invasive and non-invasive mechanical ventilation, and the main ventilator settings. It also highlights the potential complications of mechanical ventilation, the basic principles of weaning, and the pathophysiological basis of patient-ventilator dyssynchrony.
In conclusion, this review reported that IL-37 has a crucial role in reducing infection-associated inflammation and has a good impact on inflammation-induced pathology. However, tight regulation that achieved balance between effector immune responses that required for pathogen elimination and limited tissue damage that resulted from excessive inflammation should be existed in the potential IL-37 therapy to prevent clinical complications of a disease.
