The release of glutamate during brain anoxia or ischaemia triggers the death of neurons, causing mental or physical handicap. The mechanism of glutamate release is controversial, however. Four release mechanisms have been postulated: vesicular release dependent on external calcium or Ca2+ released from intracellular stores; release through(More)
Active transport across the vacuolar components of the eukaryotic endomembrane system is energized by a specific vacuolar H+-ATPase. The amino acid sequences of the 70- and 60-kDa subunits of the vacuolar H+-ATPase are approximately equal to 25% identical to the beta and alpha subunits, respectively, of the eubacterial-type F0F1-ATPases. We now report that(More)
Tau proteins are a class of low molecular mass microtubule-associated proteins that are specifically expressed in the nervous system. A cDNA clone of adult rat tau was isolated and sequenced. To analyze functions of tau proteins in vivo, we carried out transfection experiments. A fibroblast cell line, which was transfected with the cDNA, expressed three(More)
BACKGROUND Several nonpharmacological interventions, including exercise, are recommended in primary prevention of hypertension and other cardiovascular diseases in which the pathogenetic role of endothelial dysfunction has been suggested. We studied the effects of long-term aerobic exercise on endothelial function in patients with essential hypertension. (More)
The complete genomic sequence of an aerobic thermoacidophilic crenarchaeon, Sulfolobus tokodaii strain7 which optimally grows at 80 degrees C, at low pH, and under aerobic conditions, has been determined by the whole genome shotgun method with slight modifications. The genomic size was 2,694,756 bp long and the G + C content was 32.8%. The following(More)
The effects of long-term aerobic exercise on endothelial function in patients with essential hypertension remain unclear. To determine whether endothelial function relating to forearm hemodynamics in these patients differs from normotensive subjects and whether endothelial function can be modified by continued physical exercise, we randomized patients with(More)
OBJECTIVES The purpose of this study was to compare the effect of different antihypertensive agents, calcium antagonists, angiotensin-converting enzyme (ACE) inhibitors, beta-blockers and diuretic agents on endothelial function. BACKGROUND Endothelial dysfunction is a component of essential hypertension, and various antihypertensive drugs may be able to(More)
FGF23 suppresses both serum phosphate and 1,25-dihydroxyvitamin D [1,25D] levels in vivo. Because 1,25D itself is a potent regulator of phosphate metabolism, it has remained unclear whether FGF23-induced changes in phosphate metabolism were caused by a 1,25D-independent mechanism. To address this issue, we intravenously administered recombinant FGF23 to(More)
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) aims to resect large neoplastic lesions en bloc, allowing for more precise histopathological analysis. The present retrospective study aimed to analyze the technical and clinical outcomes after ESD of colorectal tumors. PATIENTS AND METHODS ESD was performed for the treatment of 71(More)
