Nitric oxide (NO) has been implicated in the neuronal hyperexcitability hence its involvement in the pathophysiology of epilepsy is clear. However, some studies indicate that NO has anticonvulsant effects while others present its convulsive effects. In the present study we tested the involvement of NO in pentylenetetrazol (Metrazol) induced Status(More)
INTRODUCTION Traumatic brain injury (TBI) is one of the major causes of death in the world, with at least ten million serious traumatic brain injuries occurring annually; nevertheless, the pathophysiologic events taking place immediately after the injury are not yet fully known. OBJECTIVE To study the effects of TBI on brain hemodynamic, metabolic and(More)
Middle cerebral artery occlusion (MCAO), which leads to focal cerebral ischemia, serves as an experimental model for brain stroke. There is a large variation in protocols and techniques using the MCAO model, which may affect the outcomes seen in different studies. The current work presents and compares the diverse responses in mitochondrial NADH and(More)
Focal cerebral ischemia creates a gradual injury, ranging from severe injury in the core towards moderate damage in the penumbra. Disruption of blood supply leads to shortage in oxygen supply, resulting in mitochondrial disruption in the ischemic area. The present work study the mitochondrial function and microcirculatory blood supply in the core and(More)
The 'Cushing Response' is a significant phenomenon associated with elevated ICP. The purpose of our study was to examine the effects of the intracranial hypertension level and duration on the cerebral tissue physiology, using a Multiprobe assembly (MPA). The parameters monitored simultaneously included ICP, CBF, mitochondrial NADH redox state, extracellular(More)
Here, we report the draft genome sequence of a Gram-negative microbe found in a blood culture (B08008) from a patient. The organism was proposed to be from a new unknown genus and species. This publication will increase worldwide microbial knowledge and may improve microbial identification and antibiotic treatment for patients.
We report here the draft genome sequence of the Suttonella ornithocola bacterium. To date, this bacterium, found in birds, passed only phylogenetic and phenotypic analyses. To our knowledge, this is the first publication of the Suttonella ornithocola genome sequence. The genetic profile provides a basis for further analysis of its infection pathways.
Under body O 2 imbalance, the Autonomic Nervous System is responsible for redistribution of blood flow with preference to the most vital organs (brain, heart), while the less vital organs (intestine, GI tract) are hypoperfused. The aim of this study was to develop and use an animal model for real time monitoring of tissue viability in the brain, and the(More)
OBJECTIVE Over the last 20 years, mannitol has replaced other osmotic diuretics. Its beneficial effects on intracranial pressure (ICP), cerebral perfusion pressure (CPP), cerebral blood flow (CBF) and brain metabolism are widely accepted. In the present study, we tested the effect of mannitol injection on brain hemodynamic, metabolic, ionic and electrical(More)
