Connectivity levels among Brazilian reef fish fauna populations have attracted growing interest, mainly between mainland shores and oceanic islands. The Pomacentridae, whose phylogeographic patterns are largely unknown in the Atlantic, are a family of dominant fish in reef regions. We present data on the variability and population structure of damselfish Chromis multilineata in different areas ...

Results Of 280 exposed patients, 9 had died without suspicion of blood-borne infection, 3 could not be tested, and 5 declined investigations. Among the 263 (93%) tested patients, 218 (83%) had negative results. We confirmed a known history of HCV infection in 6 patients (1 coinfected by HIV), and also identified resolved HBV infection in 37 patients, of whom 18 were already known. 2 patients we...

The hepatitis C virus glycoprotein E2 receptor-binding domain is encompassed by amino acids 384 to 661 (E2(661)) and contains two hypervariable sequences, HVR1 and HVR2. E2 sequence comparisons revealed a third variable region, located between residues 570 and 580, that varies widely between genotypes, designated here as igVR, the intergenotypic variable region. A secreted E2(661) glycoprotein ...

Background: Diabetes mellitus increases the risk of central nervous system (CNS) disorders such as stroke, seizures, dementia, and cognitive impairment. Berberine, a natural isoquinolne alkaloid, is reported to exhibit beneficial effect in various neurodegenerative and neuropsychiatric disorders. Moreover astrocytes are proving critical for normal CNS function, and alterations in their activity...
