Organic solvents and time-dependent sensitization.
The nervous system is main target of the toxic action of most of organic solvents. There is little doubt that occupational solvent exposure may result in persisting neurobehavioural disturbances--the organic solvent syndrome. Recently, the solvents are quoted among possible causes of the abnormal condition referred to as multiple chemical sensitivity (MCS), and which is characterized by a psych...
متن کاملMorphine sensitization and state-dependent learning in mice
In the present study, the effects of morphine sensitization on morphine-induced impairment of memory formation and the state-dependent retrieval of a passive avoidance task learned under morphine influence have been investigated in mice. Pre-training administration of morphine (0.5, 2.5 and 5 mg/kg) dose dependently suppressed the learning of one-trial passive avoidance task. Pre-test administr...

متن کاملIdentifying a Time - dependent Covariate E ect in theAdditive Risk
SUMMARY We develop a method to identify a time dependent covariate eeect in the partly parametric additive risk model. The proposed method is based on a formal hypothesis test, whereas previously only an ad hoc procedure was available. Rates of convergence of restricted maximum likelihood estimators of regression coeecients based on the method of sieves play an important role in the development...
متن کاملMeasurement and Prediction of Time-independent and Time-dependent Rheological Behavior of Waxy Crude Oil
Wax deposition phenomenon changes the rheological behavior of waxy crude oil completely. In the current work, the rheological time-dependent and time-independent behaviors of waxy crude oil samples are studied and flow curve and compliance function are measured for the oil samples with various wax contents at different temperatures. A decrease in temperature and an increase in wax content lead ...
