Recombinant adeno-associated virus (rAAV) vectors can mediate long-term stable transduction in various target tissues. However, with rAAV serotype 2 (rAAV2) vectors, liver transduction is confined to only a small portion of hepatocytes even after administration of extremely high vector doses. In order to investigate whether rAAV vectors of other serotypes(More)
It has been suggested that stroke-prone spontaneously hypertensive rats (SHRSP) show vulnerability to neuronal damage following transient ischemia. To observe the effect of hydroxyl radicals on neuronal damage in the hippocampus of SHRSP during ischemia and recirculation, we measured the levels of 2,3-dihydroxybenzoic acid (2,3-DHBA), as a biological marker(More)
Tight junctions create a rate-limiting barrier to the diffusion of solutes between vertebrate epithelial cells and endothelial cells. They are also controlled within individual cells by a variety of physiologically relevant signals. We investigated the effects of polyunsaturated fatty acids on the formation of tight junctions in brain capillary endothelial(More)
The expressions of Bcl-2, thioredoxin (TRX) and cytochrome c oxidase III (CO III) mRNAs after hypoxia and reoxygenation (H/R) were examined by quantitative reverse transcription-polymerase chain reaction using cultured cortical neurons isolated from stroke-prone spontaneously hypertensive rats (SHRSP) and Wistar Kyoto rats (WKY). The differences in gene(More)
The incidence of cerebral lesions in stroke-prone spontaneously hypertensive rats appears to depend on the severity of the hypertension and nutritional factors. Comparison of American and Japanese commercial rat diets revealed a much higher incidence of stroke in rats receiving the Japanese diet (88% vs 30% by 9 months of age). Analyses of the diets(More)
A new tail cuff method for determining systolic and mean blood pressure in rats was developed based on photoelectric detection of tail arterial blood flow and pulsatile volume oscillation. Indirect systolic and mean blood pressure measured by this method correlated well with direct systolic and mean blood pressures recorded by a transducer and polygraph(More)
The stroke-prone spontaneously hypertensive rat (SHRSP) has been reported to show significantly lower levels of serum total cholesterol than the normotensive control strain Wistar-Kyoto rat (WKY). Because selective inbreeding was conducted for stroke proneness, this concomitantly inherited characteristic of SHRSP may play some pathophysiological role in(More)
Cerebral ischemia induces a massive efflux of glutamate causing delayed neuronal death in stroke-prone spontaneously hypertensive rats (SHRSP) but not in Wistar Kyoto rats (WKY). It is obvious that L-N-nitroarginine (L-NNA; NO synthase (NOS) inhibitor), benzamide (poly(ADP-ribose) synthetase inhibitor), and growth factors are involved in reducing neuronal(More)
Proteoglycans (PGs) were localised immunohistochemically in 52 salivary gland tumours including pleomorphic adenoma, adenoid cystic carcinoma, acinic cell carcinoma, oncocytoma, mucoepidermoid carcinoma, clear cell tumour and Warthin tumour, using antibodies raised against large PG, small PG, chondroitin 4-sulphate PG, chondroitin 6-sulphate PG, heparan(More)
