Ts65Dn mice are partially trisomic for the distal region of MMU16, which is homologous with the obligate segment of HSA21 triplicated in Down syndrome (DS). Ts65Dn mice are impaired in learning tasks that require an intact hippocampus. In order to investigate the neural basis of these deficits in this mouse model of Down syndrome, quantitative light and(More)
Septic encephalopathy is a complication of sepsis, and it is closely associated with the increased mortality of the sufferers. Pathophysiology of septic encephalopathy is not still completely understood. In an attempt to provide insight into the pathogenesis of septic encephalopathy, a light and electron microscopic investigation has been carried out in a(More)
Sepsis occurs in 14-37 percent of patients admitted to intensive care units and sepsis associated encephalopathy (SAE) is its severe complication. In an attempt to provide insight into the question how sepsis and SAE contributes cerebral dysfunction, apoptotic cell death was investigated in hippocampal formation, centers of adult neurogenesis and main(More)
Sepsis and septic shock are the commonest causes of death in the intensive care units. Although recent research have improved our understanding of the progress and pathophysiology of sepsis and septic shock, underlying mechanisms in sepsis-associated encephalopathy is still poorly understood. The incidence of sepsis-associated encephalopathy has been(More)
OBJECTIVE Topical cytidine-5'-diphosphocholine (CDP-choline) improves functional recovery and promotes nerve regeneration in sciatic nerve injury in rats. The aims of this study were to test whether systemic treatment with CDP-choline was effective in improving the recovery of injured sciatic nerve, and to determine whether the cytidine and/or choline(More)
Neurogenesis occurs in the adult brain throughout the lives of all mammals. The dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles have been established as the primary sites of adult neurogenesis, and recent studies have shown that inflammation has a modulating effect on adult neurogenesis. However, only(More)
OBJECT End-to-side neurorrhaphy has recently became popular for peripheral nerve repair. Although this method is mainly indicated in nerve defects in which there is an absent proximal nerve stump, bridging a motor nerve defect by coapting the proximal and distal ends of the defect to a neighboring mixed nerve in an end-to-side fashion has been another(More)
OBJECT This experimental study was designed to evaluate functional and sensory outcomes and morphological features observed after simultaneous end-to-side coaptations of distal stumps of two nerves to a single neighboring nerve. Studies were performed using both parallel and end-to-side coaptation (PEC) and serial end-to-side coaptation (SEC) methods in a(More)
The aim of this experimental study was to evaluate the effects of end-to-side coaptation of the proximal end of a severed nerve to the same intact nerve, in addition to traditional end-to-side coaptation of the distal end, with an aim to use the intact nerve as a nerve conduit in a rat model and to compare the functional and histologic results of this(More)
Recent theories about migraine pathogenesis have emphatized the role of the trigeminal system in the pathogenesis of migraine attacks. The local vasodilatation of intracranial extracerebral blood vessels and the consequent stimulation of surrounding trigeminal sensory nerve pain pathways are proposed to be the key mechanisms underlying the generation of(More)
