Fetal alcohol spectrum disorders occur when a mother drinks during pregnancy and can greatly influence synaptic plasticity and cognition in the offspring. In this study we determined whether there are periods during brain development that are more susceptible to the effects of ethanol exposure on hippocampal synaptic plasticity. In particular, we evaluated how the ability to elicit long-term po...

background: the term caustic generally refers to alkaline and the term corrosive generally refers to acidic agents' injury however, in medical literature caustic is frequently a term applied to both substances. ingested alkali typically damage the esophagus more than stomach or duodenum, whereas acids usually cause more severe gastric injury. since esophagus has a slightly alkaline ph, its...

abstract background: preterm labor (delivery after 20 weeks and before 37 weeks of gestation) is the leading cause of prenatal mortality in developed countries. many women who have pre term labor have abnom1ally high plasma levels of a-fetoprotein in early pregnancy. methods: this study was designed to evaluate the ability of this biochemical test and a clinical risk factor scoring system to pr...

The majority of the inhomogeneities in the chemical composition of Globular Cluster (GC) stars appear due to primordial enrichment. The most studied model today claims that the ejecta of Asymptotic Giant Branch (AGB) stars of high mass —those evolving during the first ≃100Myr of the Clusters life— directly form a second generation of stars with abundance anomalies. In this talk, we review the s...

Memory persistence needs a new event of consolidation 12h after the acquisition. We investigated the role of the cholinergic activity on the persistence of memory. For this purpose, we performed the treatments 9 or 12h after acquisition and the memory tested 2 or 7 days after inhibitory avoidance (IA) training. Here we report that activity of medial septum, by transitorily inactivating this str...
