Evaluation of acute toxicity of copper cyanide to freshwater fish, Catla catla (Hamilton) [PDF]
Journal of Central European Agriculture, 2011 The acute toxicity of copper cyanide to the juveniles of Indian major carp Catla catla (2±0.5 cm) was evaluated under static renewal conditions. The concentrations of copper cyanide that killed 50% of the carp fingerlings within 96-h (96-h LC50) was ...

A mathematical model for estimating the LC50 (or LD50) among an insect life cycle
Egyptian Academic Journal of Biological Sciences. A, Entomology, 2010 In this study, a mathematical model is made to estimate the median lethal concentration or dose (LC50 or LD50). The model is based on the data of different insecticide groups, where each one is represented by the effect of three insecticides over ...

Discovery of H2 Receptor Antagonists as Colistin Enhancers by Targeting Acid Stress Response
Advanced Science, EarlyView.This study identifies YqgB as a key target for restoring colistin susceptibility in mcr‐positive pathogens under acidic conditions by remodeling phospholipid composition and reducing LPS modification. Deep learning‐based screening reveals H2 receptor antagonists as novel colistin adjuvants. Further investigations indicate that ranitidine and famotidine
