Exposure to pesticides or solvents and risk of Parkinson disease.
OBJECTIVE To investigate the risk of Parkinson disease (PD) associated with exposure to pesticides and solvents using meta-analyses of data from cohort and case-control studies. METHODS Prospective cohort and case-control studies providing risk and precision estimates relating PD to exposure to pesticides or solvents or to proxies of exposure were considered eligible. The heterogeneity in ris...
متن کاملA role for solvents in the toxicity of agricultural organophosphorus pesticides
Organophosphorus (OP) insecticide self-poisoning is responsible for about one-quarter of global suicides. Treatment focuses on the fact that OP compounds inhibit acetylcholinesterase (AChE); however, AChE-reactivating drugs do not benefit poisoned humans. We therefore studied the role of solvent coformulants in OP toxicity in a novel minipig model of agricultural OP poisoning. Gottingen minipig...
متن کاملEffects of solvents polarity parameters on heterogeneous catalytic hydrogenation of cyclohexene in molecular solvents
Heterogeneous catalytic hydrogenation of cyclohexene, catalyzed by Pt/A1203, was carried out in thirteenvarious solvents (four alcoholic solvents, six aprotic polar solvents and three non polar solvents) at 25 °C.Single-parameter correlations of logk vs. normalized polarity parameter (ETN), hydrogen-bond acceptorbasicity (p), hydrogen-bond donor acidity (a) and dipolarity/polarizibility (it*) d...
متن کاملAminolysis of selected methylpyrimidines in protic solvents
Crystallographic data analyses indicate that three types of prolinium cations, along with two types of hydrogen bonding, produce and stabilize the helical structure of triprolinium 12-phosphomolybdate. There are similarities between this organic-inorganic compound and peptides/proteins. The stronger “conventional” hydrogen bonds and the less common C-H…O attractions play critical roles in gener...
متن کاملWater in nonaqueous solvents*
The possibility and usefulness of sinple liquid models is reported. The importance of van der Waals forces for liquid water and aqueous solutions is discussed and compared with the solubility of water in nonpolar solvents and as well as of nonpolar solvents in water. Both systems could be understood as equilibrium of few water monomers. The network of H-bonded water molecules seems to be less i...
