The Antidepressant-Like Effect of Fish Oil: Possible Role of Ventral Hippocampal 5-HT1A Post-synaptic Receptor.

The pathophysiology of depression is not completely understood; nonetheless, numerous studies point to serotonergic dysfunction as a possible cause. Supplementation with fish oil rich docosahexaenoic (DHA) and eicosapentaenoic acids (EPA) during critical periods of development produces antidepressant effects by increasing serotonergic neurotransmission, particularly in the hippocampus. In a previous study, the involvement of 5-HT1A receptors was demonstrated and we hypothesized that fish oil supplementation (from conception to weaning) alters the function of post-synaptic hippocampal 5-HT1A receptors.

[Prevalence of Chlamydia trachomatis and Neisseria gonorrhoea infections in sexual actives young women at a southern Brazilian city].

Purpose: to determine the prevalence of Chlamydia and gonorrhea in a sample of women from Curitiba.

Methods: this was a cross-sectional study with a sample of sexually active non-pregnant women aged between 16 and 23 years-old, with an intact uterus, with up to four sexual partners, without evidence of fever or purulent cervicitis, submitted to pelvic examination and PCR-based urine- testing for Chlamydia and gonorrhea. Exclusion criteria included: vaccination for HPV, vaccination history for the past 21 days, previous abnormal cytology, history of genital warts, splenectomy, immune disorders, and use of immunosuppressive drugs.
