OBJECTIVE Tissue plasminogen activator (tPA) is approved for treatment of acute ischemic stroke, but it increases the risk of cerebral hemorrhage. Accumulating evidence suggests that von Willebrand factor (VWF) plays a pivotal role in thrombus formation and microcirculatory disturbances after ischemic stroke. By cleaving VWF, ADAMTS13 (a disintegrin and(More)
BACKGROUND AND PURPOSE Inflammatory responses and blood-brain barrier (BBB) dysfunction play important roles in brain injury after intracerebral hemorrhage (ICH). The metalloprotease ADAMTS 13 (a disintegrin and metalloprotease with thrombospondin type I motif, member 13) was shown to limit inflammatory responses through its proteolytic effects on von(More)
Stroke is a leading cause of long-lasting disability in humans. However, currently there are still no effective therapies available for promoting stroke recovery. Recent studies have shown that the adult brain has the capacity to regenerate neurons after stroke. Although this neurogenic response may be functionally important for brain repair after injury,(More)
In the mammalian brain, neurogenesis persists throughout the embryonic period and adulthood in the subventricular zone of the lateral ventricle and the granular zone (dentate gyrus) of the hippocampus. Newborn neural progenitor cells (NPCs) in the two regions play a critical role in structural and functional plasticity and neural regeneration after brain(More)
OBJECTIVES Isolation and purification of adult stem cells (ASC) are a great challenge. Our objectives were to determine whether ASC are more heat-tolerant than non-stem cells, and to explore if ASC could be enriched by heat-stress treatments. MATERIALS AND METHODS Rat dental follicle cells were cultured in a variety of media to obtain either a(More)
PURPOSE To examine the influence of topical administration of calcitriol on dry eye (DE) related corneal inflammation. METHODS Benzalkonium chloride (BAC, 0.2%) was applied to induce DE. Then rats were treated topically with calcitriol (10-6μM). Tear break-up time (TBUT), fluorescein staining score, inflammatory index, and tear volume were measured.(More)
