Ruthenium(II)-mercapto complexes induce cell damage via apoptosis pathway on ovarian cancer cells.

Ovarian cancer represents a leading cause of cancer-related deaths in women worldwide. Chemotherapeutic agents are usually employed to treat the patients, and Ruthenium(II)-based compounds have been investigated as possible substitutes for platinum drugs. In this work, we studied three different Ru(II)-phosphine-mercapto complexes (1-3) as potential cytotoxic agents against A2780 and A2780-cisR ovarian cancer cells.

Cytotoxic Ruthenium(II)-Diphosphine Complexes Affect the Mitochondrial Respiration of Lung Cancer Cells.

In this work, we studied six Ruthenium(II)-diphosphine compounds containing different mercapto ligands (N-S), with general formula [Ru(N-S)(dppm)]Cl (dppm=1,1-bis(diphenylphosphino)methane). These compounds were characterized by several techniques (NMR [H, P(H), and C], HRMS, IR, UV-Vis and XRD) and their purity confirmed by elemental analysis. DLS experiments revealed low diameters and polydispersity indexes, and positive log P values in n-octanol/PBS indicated their preference for the organic phase.

XbaI polymorphism in the APOB gene and its association with increased cholesterol in children and adolescents: Ouro Preto study.

Atherosclerotic vascular changes can begin during childhood, providing risk for cardiovascular disease (CVD) in adulthood. Identifiable risk factors such as dyslipidemia accelerate this process for some children. The apolipoprotein B (APOB) gene could help explain the inter-individual variability in lipid levels among young individuals and identify groups that require greater attention to prevent CVD.

Seroprevalence of Hepatitis E Virus Among Schistosomiasis mansoni Patients Residing in Endemic Zone in Brazil.

The occurrence of hepatitis E virus (HEV) in patients with Schistosomiasis mansoni (SM) is still poorly understood in Brazil. The objective of this study was to estimate the seroprevalence of anti-HEV IgG in patients with SM and its association with the periportal fibrosis (PPF), assessed by serum markers and ultrasound criteria. This cross-sectional study was carried out in an endemic area in Pernambuco, Brazil, with schistosomal patients who underwent coproscopic survey.
