Teak (Tectona grandis L.f.) is one of the most durable timbers in the world that is used for all conceivable purposes. Its widespread use has constrained the distribution of species to small and isolated populations. The genetic structure within and between nine natural teak growing forests of the Western Ghats of India belonging to the states of Kerala,(More)
In order to assess the role of circulating blood in early microglial activation after traumatic brain injury (TBI), controlled cortical impact injury was applied to adult rat brain slices (400 microm in thickness) and the microglial response was examined. The complement receptor (CR3) expression and morphological transformation of the microglia were(More)
Doublecortin (DCX)-immunoreactive (-ir) cells are candidates that play key roles in adult cortical remodeling. We have previously reported that DCX-ir cells decrease after stress exposure or global brain ischemia (GBI) in the cingulate cortex (Cg) of rats. Herein, we investigate whether the decrease in DCX-ir cells is exacerbated after GBI due to acute(More)
In order to prevent thrombo-embolism after prosthetic valve replacement, a high dose therapy with 450 mg/day of Dipyridamole and 3,000 mg/day of Aspirin was carried out for 1 year and 2 months in 91 cases (26 cases with aortic valve replacement, 40 cases with mitral valve replacement and 25 cases with multiple valve replacement). In the treated group, the(More)
A case of superior sagittal sinus thrombosis which was complicated with ulcerative colitis is reported. A 16-year-old male patient had a 2-year history of ulcerative colitis. He was admitted to our hospital complaining of abdominal pain, bloody bowel discharge and appetite loss, and was then treated conservatively. Two days after admission, he demonstrated(More)
Following CNS injury, microglia respond and transform into reactive species exhibiting characteristic morphological changes that have been termed "activated" or "ameboid" microglia. In an attempt to establish that microglial reactions induced immediately after injury are caused by intrinsic mechanisms rather than infiltration of blood and its constituents,(More)
OBJECTIVE Both microglia and astrocytes respond immediately to traumatic brain injury (TBI). The present study was undertaken to examine whether or not excitatory amino acid (EAA) antagonists could attenuate such glial responses. METHODS EAA antagonists, including the broad spectrum EAA antagonist, kynurenic acid (KYN), specific N-methyl-D-aspartate(More)
OBJECTIVE Ruptured vertebral artery dissecting aneurysms (VADA) should be treated promptly because of the high risk of rebleeding. However, it is difficult to treat dissecting aneurysm during the acute stage using microsurgery because of high intracranial pressure or brain edema. Therefore, endovascular treatment of the ruptured VADA may be a better(More)
Exposure to acute stress by forced swim impairs spatial learning and memory in rats. The retrosplenial cortex plays an important role in spatial learning and memory. A cell population that expresses immature neuronal markers, including doublecortin (DCX), plays a key role in plasticity of the adult brain through formation of new neurons. Here, we aimed to(More)
