Objective(s): In the present study, we investigated the effect of ischemic preconditioning (IPC) on c-myb immunoreactivity as well as neuronal damage/death after a subsequent lethal transient ischemia in gerbils. Materials and Methods: IPC was subjected to a 2 min sublethal ischemia and a lethal transient ischemia was given 5 min transient ischemia. The animals in all of the groups were given ...
the beet armyworm (spodoptera exigua hübner) is an important pest of many agricultural crops all over the world. most of the sugar beet growing regions in iran are infested. in this study, the acute lethal effects of pyriproxyfen, spinosad, and indoxacarb as well as sublethal effects of pyriproxyfen on the 1st instar s. exigua were assessed by leaf dip bioassay method. mortality was recorded 48...
the purpose of the research was determine the effects of gamma ray on seed germination, seedling height and root length of rice (oryza sativa l. spp. indica cv. mr219) to identify the lethal dosage of the radiation. paddy seeds of mr219 were exposed to different doses of gamma radiations viz 50,100,150,200,250,300,350,400,450,500,600,700,800,900 and 1000 gy using 60co as the radiation source. t...
background: diazinon is an organophosphorous pesticide which widely found in municipal, agricultural, and urban storm water discharges. the present study was conducted to achieve lethal concentration (lc50) and behavioral changes of rutilus rutilus caspius and hypophthal-micthys molitrix after exposure to lethal concentration of diazinon. methods: the experiment was carried out in static condit...
Lethal injections have been increasingly employed in China nowadays. Due to the lack of specific institutions in China’s legislation, there is no universal and definite standard for the options and execution procedure of lethal injections, causing lots of problems. Therefore, an option for lethal injections should be established and relevant execution procedure should be further improved as well.
background: the development of toxicity tests regarding toxic responses of different fish species could be more effectively used in predictive toxicology and risk assessment. in this study lethal concentrations (lc50-96 h) values of copper sulphate an important toxic industrial pollutant, on capoeta fusca were determined. behavioral changes at different concentrations of cuso4 were determined f...
