Parathion, also called parathion-ethyl or diethyl parathion, is an organophosphate insecticide and acaricide.It was originally developed by IG Farben in the 1940s. It is highly toxic to non-target organisms, including humans, so its use has been banned or restricted in most countries.
Parathion S is an organophosphate related to the organophosphate insecticide paraoxon and parathion. It's the structural isomer of parathion.
It is an organophosphate oxon, and the active metabolite of the insecticide parathion. It is also used as an ophthalmological drug against glaucoma . Paraoxon is one of the most potent acetylcholinesterase-inhibiting insecticides available, around 70% as potent as the nerve agent sarin , and so is now rarely used as an insecticide due to the ...
Parathion methyl, or methyl parathion, is an organophosphate insecticide, possessing an organothiophosphate group. It is structurally very similar to parathion-ethyl . It is not allowed for sale and import in nearly all countries around the world, while a few allow it under subject to specified conditions only.
It was proposed that, in order to avoid damage to the DNA genome of the oocytes, the metabolism contributing to the synthesis of much of the oocyte's constituents was shifted to other maternal cells that then transferred these constituents to oocytes. [7] [8] Thus, oocytes of many organisms are protected from oxidative DNA damage while storing ...
In other words, primary oocytes reach their maximum development at ~20 weeks of gestational age, when approximately seven million primary oocytes have been created; however, at birth, this number has already been reduced to approximately 1-2 million per ovary. At puberty, the number of oocytes decreases even more to reach about 60,000 to 80,000 ...
Time course of drug plasma concentrations over 96 hours following oral administrations every 24 hours (τ). Absorption half-life 1 h, elimination half-life 12 h. Biological half-life ( elimination half-life , pharmacological half-life ) is the time taken for concentration of a biological substance (such as a medication ) to decrease from its ...
Plasmodium falciparum is a protozoan parasite, one of the species that causes malaria in humans. A gametocyte in Plasmodium falciparum is a cell specializing in the transition between the human and the mosquito host. Gametocytes arise from erythrocytic asexual stages.
