2,3 An intrahepatic venovenous fistula was diagnosed 25 years after surgical closure of an atrial septal defect (ASD). The fistula developed after inadvertent malposition of LEE011 cost the patch, which directed inferior vena caval (IVC) flow to the LA and also divided hepatic venous return. The pressure difference between the IVC and LA to the right atrium (RA) obviously opened up hepatic vessels and thus created a large shunt from the IVC to the RA. There are close relations to similar findings after the Fontan operation with partial exclusion of

HVs.”
“The endocannabinoid and serotonin systems share a high level of overlap in terms of the physiological processes that they regulate, however, little is known about their functional interactions particularly during adolescence, a vulnerable period for both the development of psychosis and for initiation to substance use. In the present study, the effects of cannabinoid treatment on serotonin 5HT1A receptor density and mRNA expression were investigated in two age groups: Adolescent (postnatal day 35) and adult (postnatal day 70) rats were injected with the synthetic AZD1080 supplier cannabinoid HU210 (25, 50 or 100 mu g/kg) or vehicle for

1, 4 or 14 days and sacrificed 24 h after the last injection. 5HT1A receptor density was measured in different brain regions using [(3)H]8-OH-DPAT quantitative autoradiography whereas mRNA expression was measured in adjacent brain sections. Higher levels of both serotonin 5HT1A receptor binding of and mRNA expression were observed in limbic regions in adolescent control animals compared to adults. 5HT1A receptor density was increased by 23% in the CA1 region of the hippocampus of adult rats treated with 100 mu g/kg HU210 for 4 days compared to vehicle treated controls. The same treatment increased mRNA expression by 27% and by 14% in the CA1 region and dentate gyrus of the hippocampus respectively. 5HT1A receptor density was increased by 22% in the CA1 of adult animals treated with 50 mu g HU210, by 26% in the dentate gurus of adult rats treated with

100 mu g for 14 days. By contrast, 5HT1A receptor density or mRNA expression was not affected in the brain of adolescent animals in any of the brain regions examined. These results suggest that cannabinoid treatment has differential effects on serotonin-related neurochemistry in adolescent compared to adult rats. The effects in the adult brain may compromise hippocampal function and could account for the cognitive deficits seen in habitual heavy cannabis users. (C) 2010 IBRO. Published by Elsevier Ltd.
