The cumulative number of notified HIV-2 infections in Portugal was 1813 by the end of December 2008.

Influence of progesterone on GAD65 and GAD67 mRNA expression in the dorsolatera...

Progesterone modulates the GABA system and attenuates the effects of cocaine; however, there is no information about its relevance in changing GABA synthesis pathways after cocaine administration to female rats. Our objective was to investigate the influence of progesterone on the effects of repeated ...

Behavioral changes induced by cocaine in mice are modified by a hyperlipidic di...

The objective of the present study was to determine if the acute behavioral effects of cocaine acutely administered intraperitoneally (ip) at doses of 5, 10 and 20 mg/kg on white male CF1 mice, 90 days of age, would be influenced by leptin acutely administered ip (at doses of 5, 10 and 20 µg/kg) or by endogenous leptin production enhanced by a high-fat diet. The acute behavioral effects of cocaine were evaluate...

Human serum alcaline phosphatase and ageing.

In experimental ageing models an inverse relationship between age and alkaline phosphatase activity has been observed.To characterize serum levels of alkaline phosphatase activity in humans according to age and gender.Serum alkaline phosphatase was determined in a random sample of 203 community dwellers aged 40 or more years.In men (n=87) total serum alkaline phosphatase markedly increased from the 5th to the 6...

Effect of pilocarpine mouthwash on salivary flow

Pilocarpine is a cholinergic agonist that increases salivary flow and has been used to treat xerostomia. Oral intake is the most frequent route of administration. Adverse effects are dose-dependent and include sudoresis, facial blushing and increased urinary frequency.

Acute effect of different antidepressants on glycemia in diabetic and non-diabe...

Treatment with antidepressant drugs can directly interfere with blood glucose levels or may interact with hypoglycemic agents. The treatment of depression in diabetic patients must take into account variations of glycemic levels at different times and a comparison of the available antidepressant agents is important. In the prese...
