, but is not essential. The method has been used to study the enzyme in human erythrocytes and homogenates of rat brain, kidney, lungs, liver and muscle tissue. Kinetic constants determined by this system for erythrocyte cholinesterase are presented. The data obtained with acetyl-thiocholine as substrate are similar

Abstract. Brain homogenate was used as a model system to study antioxidant properties of several natural and synthetic antioxidants under oxidative stress. Oxidative stress was induced by Fe/ascorbate system and lipid peroxidation as well as protein modification were studied. Thiobarbituric acid

support the proposal that cockroach cuticle permeability is hormonally controlled, to the extent that compounds extracted from the brain have been shown to be capable of inducing permeability change over relatively short periods. Fresh brain homogenate injections from hydrated donors produced a 28

The objective of the present study was to examine the accuracy of using unbound brain concentration determined by a brain homog-enate method (Cub), cerebral spinal fluid concentration (CCSF), and unbound plasma concentration (Cup) as a surrogate for brain in-terstitial fluid concentration

Conditions have been established for the fractionation of subcellular components of rat forebrain homogenates by zonal isopycnic equilibration in continuous sucrose density gradients using a B-XIV rotor. The fractions were analyzed biochemically and by ultrastructural morphometry. Starting from

ABSTRACT Melatonin protection against in vitro kainic acid-induced oxidative damage in homogenates from different rat brain regions is shown. Braindisrupted cell homogenates from cerebral cortex, cerebellum, hippocampus, hypothalamus, and corpus striatum were incubated with kainate (11.7 m

Kendall’s coefficient concordance (KCC) can measure the similarity of a number of time series. It has been used for purifying a given cluster in functional MRI (fMRI). In the present study, a new method was developed based on the regional homogeneity (ReHo), in which KCC was used to measure
