BACKGROUND Pericytes are multifunctional cells surrounding capillaries and postcapillary venules. In brain microvasculature, pericytes play a pivotal role under physiological and pathological conditions by producing reactive oxygen species (ROS). The aims of this study were to elucidate the source of ROS and its regulation in human brain pericytes. (More)
BACKGROUND Vascular endothelial growth factor (VEGF) is a well-known molecule mediating neuronal survival and angiogenesis. However, its clinical significance in ischemic stroke is still controversial. The goal of this study was to examine the temporal profile of plasma VEGF value and its clinical significance in ischemic stroke with taking its subtypes(More)
BACKGROUND AND PURPOSE Variable sex differences in clinical outcomes after stroke have been reported worldwide. This study aimed to elucidate whether sex is an independent risk factor of poor functional outcome after acute ischemic stroke. METHODS Using the database of patients with acute stroke registered in the Fukuoka Stroke Registry in Japan from 1999(More)
OBJECTIVE Although adiponectin is a major adipocytokine that affects the pathogenesis of various cardiovascular diseases, its clinical significance in stroke remains controversial. We investigated the clinical significance of plasma adiponectin for the diagnosis, neurological severity and functional outcomes of patients with ischemic stroke. METHODS We(More)
The central nervous system (CNS) pericytes play an important role in brain microcirculation. Na(+)/H(+) exchanger isoform 1 (NHE1) has been suggested to regulate the proliferation of nonvascular cells through the regulation of intracellular pH, Na(+), and cell volume; however, the relationship between NHE1 and intracellular Ca(2+), an essential signal of(More)
BACKGROUND AND PURPOSE The relationship between the intensity of anticoagulation at the onset of acute cardioembolic stroke and clinical outcome after stroke is unclear. Here, we elucidated the relationship between prothrombin time-international normalized ratio (PT-INR) values on admission and clinical outcomes in patients with acute cardioembolic stroke.(More)
BACKGROUND AND PURPOSE Although plasma C-reactive protein (CRP) is elevated in response to inflammation caused by brain infarction, the association of CRP with clinical outcomes after acute ischemic stroke remains uncertain. This study examined whether plasma high-sensitivity CRP (hsCRP) levels at onset were associated with clinical outcomes after acute(More)
The relationship between the poststroke blood pressure (BP) and functional outcomes in patients with acute ischemic stroke is still controversial. The aim of the present study was to elucidate the impact of the poststroke BP on the clinical outcomes of acute ischemic stroke. Among the patients in the Fukuoka Stroke Registry, 1874 patients with first-ever(More)
Fibrosis is concomitant with repair processes following injuries in the central nervous system (CNS). Pericytes are considered as an origin of fibrosis-forming cells in the CNS. Here, we examined whether platelet-derived growth factor receptor β (PDGFRβ), a well-known indispensable molecule for migration, proliferation, and survival of pericytes, was(More)
Amino acid-starved yeast activates the eIF2alpha kinase Gcn2p to suppress general translation and to selectively derepress the transcription factor Gcn4p, which induces various biosynthetic genes to elicit general amino acid control (GAAC). Well-fed yeast activates the target of rapamycin (TOR) to stimulate translation via the eIF4F complex. A crosstalk was(More)
