Neuroserpin is a member of the serpin superfamily that is expressed principally in neurons of the central and peripheral nervous systems. Neuroserpin's spatial-temporal expression during development and in the adult brain suggests possible roles in synaptogenesis and synaptic plasticity. This is supported by behavioral changes in transgenic mice(More)
Shelf-lives of liquid pharmaceutical preparations (injectable and oral solution) containing phenobarbital sodium, commercially available in Brazil, were predicted by accelerated stability test using isothermal method (at 37 degrees C, 50 degrees C and 75 degrees C). Data obtained in high temperature studies using Arrhenius relation were applied to predict(More)
Two methods are described for the determination of rifampicin and isoniazid in mixtures by visible spectrophotometry and first-derivative ultraviolet spectrophotometry. The absorbance at 475 nm in buffer solution pH 7.4 was employed to determine rifampicin after applying the three-point correction technique between 420 and 520 nm, while the amplitude of the(More)
The purpose of this study was to use functional magnetic resonance imaging (fMRI) to investigate the response of the visual cortex to unilateral primary open-angle glaucoma (POAG). Specifically, we assessed whether regions of V1 and V2 with lost input from the glaucomatous eye had a greater response to input from the nonaffected fellow eye. Nine(More)
1. The aim was to identify the individual human cytochrome P450 (CYP) enzymes responsible for the in vitro N-demethylation of hydromorphone and to determine the potential effect of the inhibition of this metabolic pathway on the formation of other hydromorphone metabolites. 2. Hydromorphone was metabolized to norhydromorphone (apparent Km = 206 - 822(More)
BACKGROUND AND PURPOSE Recovery of upper-limb motor impairment after first-ever ischemic stroke is proportional to the degree of initial impairment in patients with a functional corticospinal tract (CST). This study aimed to investigate whether proportional recovery occurs in a more clinically relevant sample including patients with intracerebral hemorrhage(More)
