Ghrelin and eating disorders

Background Ghrelin is a potent hormone with central and peripheral action. This hormone plays an important role in the regulation of appetite, food intake, and energy balance. Studies have suggested that ghrelin is involved with eating disorders (ED), particularly bingeing and purging. Genetic variants have also been studied to explain changes in eating behavior. Methods We conducted a literature review; we sea...

Background There is evidence from animal and in vitro models of the protective effects of caffeine in Alzheimer’s disease. The suggested mechanisms through which caffeine may protect neurons against Alzheimer’s disease pathology include the facilitation of beta-amyloid clearance, upregulation of cholinergic transmission, and increased neuronal plasticity and survival. Epidemiological studies support that Alzhei...

In this study, we investigated the associations between single-nucleotide polymorphisms in GAB2 (rs2373115), GSK3B (rs6438552) and SORL1 (rs641120) and Alzheimer's disease (AD), both alone and in combination with the APOE*4 allele.

Angiotensina II bloqueia a consolidação e a evocação de memórias aversivas

O sistema renina - angiotensina tem um papel importante e bem descrito na modulação do sistema cardiovascular. Sua participação em processos cognitivos tem sido assunto de diversos trabalhos. É de particular interesse a modulação da memória pela ação de seus metabólitos funcionais, angiotensina II (AII) e IV (AIV), no sistema nervoso central. Apesar dos diversos trabalhos abordando o assunto, o papel da AII no ...
