MATERIAL AND METHODS The experiments were performed on the larvae and adults of the fruit-fly (Drosophila virilis). The DDT preparation used was in form of an emulsion, (one per cent DDT, one per cent lecithin, ten per cent peanut oil, emulsified in a...
Schulten [61] performed molecular simulations of systems including DOM, water, and the xenobiotic pentachlorophenol (a pesticide), atrazine (a herbicide), and DDT (an insecticide). Geometry optimization calculations were performed to analyze energetics and hydrogen bonds. It was found that van der ...
Growing concern has arisen from the quasi-exponential increase in the numbers and quantities of man-made chemicals that presently are in current use, and their potential effects on human health, especially their delayed effects on degenerative diseases s
Though it has been the drug of choice for many advanced medical and surgical procedures with a long history, the adverse events, such as bleeding, heparin-induced thrombocytopenia (HIT), allergic reactions, follow. Therefore, low molecular weight heparins (LMWHs) and ultra low molecular weight ...
aeolicus LPS and 250 µL of Ni-NTA resin were mixed with binding buffer (25 mM Tris pH 8.5, 50 mM NaCl, 20 mM imidazole, 1 mM DDT) in a 750 µL total volume. The CBD and A. aeolicus LPS were incubated on a rotor at room temperature. Ni-NTA resin was pellet...
Around half the residues in AF2 predictions of the 11 model species are of low confidence, many of which may correspond to regions without a well-defined structure in isolation. It has been shown that regions with low pLDDT are often intrinsically disordered proteins or regions (IDPs/IDRs)13...
The cup assembly is weighed regularly until a constant rate of weight change is achieved. The steady-state flux is calculated as the ratio of the constant rate of weight change to the area of the specimen exposed to moisture movement. There are many variations of the diffusion cup method for...
1. 1. Polyacrylamide gel electrophoresis in Tris/glycine buffer (pH 8.3) revealed five forms of acetylcholinesterase (acetylcholine hydrolase, EC 3.1.1.7) in the 100 000 × g, 1-h supernatants of aqueous fly-head extracts from the DDT/S strain. Five other housefly strains (CSMA, Bayer 21/...
Enzymatic breakdown of sphingomyelin by sphingomyelinase (SMase) is the main source of the membrane lipids, ceramides, which are involved in many cellular physiological processes. However, the full-length structure of human neutral SMase has not been res
(aldrin, BHC-alpha, -beta, -delta, chlordane, DDT-related compounds, dieldrin, endrin, HCB, heptachlor, heptachlor epoxide, lindane, methoxyclor, mirex, PCB) and organophosphates (diazinon, disulfoton, ethion, malathion, methyl parathion, parathion [ethyl], phorate [thimet], thiodan [...
