AIM The aim of this study was to study the anatomy of different parts of brain and histology of hippocampus of Vencobb broiler chicken. MATERIALS AND METHODS A 12 adult experimental birds were sacrificed by cervical dislocation. After separation of the brain, gross anatomy features were studied. Brain tissue was fixed in 10% buffered neutral formalin for 2-3 days, and then routine dehydration...
CHEEK, DONALD B., JOAN E. GRAYSTONE, AND RICHARD D. ROWE. Hypoxia and malnutrition in newborn rats: effects on RNA, DNA, and protein in tissues. Am. J. Physiol. 217(3): 642-645. 1969.-Newborn male rats were exposed to 12% oxygen from 1 to 7 days and their brain weights, DNA, protein, or RNA content studied at 7, 21, or 35 days. At 35 days, studies were made of cerebrum and cerebellum and of the...
The cerebrum of mammals spans a vast range of sizes and yet has a very regular structure. The amount of folding of the cortical surface and the proportion of white matter gradually increase with size, but the underlying mechanisms remain elusive. Here, two laws are derived to fully explain these cerebral scaling relations. The first law holds that the long-range information flow in the cerebrum...
This study investigated what effect a 30% oxygen administration had on visuospatial cognitive performance and cerebral activation and lateralization using fMRI. Eight college students were selected as the subjects for this study. An oxygen dispenser that provided 21% and 30% oxygen at a constant rate of 8L/min was developed. In order to measure the performance level of visuospatial cognition, t...
Genetic variations in the vacuolar protein sorting 10 protein (Vps10p) family have been linked to Alzheimer's disease (AD). Here we demonstrate deposition of fragments from the Vps10p member sortilin at senile plaques (SPs) in aged and AD human cerebrum. Sortilin changes were characterized in postmortem brains with antibodies against the extracellular and intracellular C-terminal domains. The t...
Epidural anesthesia is often used form in Chinese primary hospitals and lidocaine is the most favorite anesthetic. Fatalities due to epidural anesthesia accident and lidocaine overdose are often happened, but there still have not obvious evidence to indicate the real reason of death according to the concentration of lidocaine in postmortem blood because the postmortem redistribution (PMR). An a...
This paper describes the automatic Adaptive Disconnection method to segment cerebral and cerebellar hemispheres of human brain in three-dimensional magnetic resonance imaging (MRI). Using the partial differential equations based shape bottlenecks algorithm cooperating with an information potential value clustering process, it detects and cuts, first, the compartmental connections between the ce...
Sixty-eight female neonatal pigs selected for seven (Experiment 1) or eight (Experiment 2) generations for high (HG) or low (LG) plasma cholesterol were used to test the hypothesis that neonatal dietary cholesterol fed during the first 4 or 8 wk of postnatal life increases the cholesterol content of the cerebrum in young adulthood following free access to a high-fat (15%), high-cholesterol (0.5...
