Mechanisms underlying the pathogenesis of psychotic disorders were explored by monitoring the expression of GABAergic neurons in an animal model. Male rats of postnatal days 21 and 60 were intraperitoneally injected with amphetamine (Amph), 5 mgkg, or saline three times daily for 6 d. After 1-d or 14-d withdrawal from Amph, they were challenged on day 8(More)
Mechanisms underlying the short-term effects of amphetamine (AMPH) were examined by monitoring the expression of metabotropic glutamate receptor 5 (mGluR5) in cultured rat neurons. The cortical and hippocampal neurons were incubated with 0.1–100 µM of AMPH for 1 h or 1 µM of AMPH for 10 min to 3 h. Immunocytochemical and in situ hybridization (ISH) analyses(More)
P-cresol is a well-known uremic toxin and environmental toxicant that may affect platelet functions. In this study, p-cresol (1-5 μM) inhibited the arachidonic acid (AA)-induced platelet aggregation, with 47% and 82% of inhibition at concentrations of 2 and 5 μM, respectively. Under similar experimental condition, p-cresol showed little effect on the(More)
The distribution of zinc (Zn) concentration in the blood and erythrocytes of common carp, grass carp, silver carp and tilapia was studied. It was found that in whole blood, the average Zn concentrations in these four species of fish (approx. 6–14 μg/[ml whole blood]) were relatively similar to those in other species of fish and mammals. However, the mean Zn(More)
The success rate in previous attempts at transforming human umbilical mesenchymal stem cells (HUMSCs) isolated from Wharton's jelly of the umbilical cord into dopaminergic cells was a mere 12.7%. The present study was therefore initiated to establish a more effective procedure for better yield of dopaminergic cells in such transformation for more effective(More)
The short and long isoforms of the dopamine D2 receptor (D2S and D2L respectively) are highly expressed in the striatum. Functional D2 receptors activate an intracellular signalling pathway that includes a cAMP-independent route involving Akt/GSK3 (glycogen synthase kinase 3). To investigate the Akt/GSK3 response to the seldom-studied D2S receptor, we(More)
We studied the link between high zinc levels and the extreme stress tolerance of common carp. Fish under stress showed much higher plasma cortisol levels than controls. Stress or cortisol injection induced large changes in zinc levels in the common carp but not in grass carp, silver carp or tilapia. The effect of 5 days of anoxia and 4 subsequent days of(More)
