A new beta-cyclodextrin (beta-CD) derivative, 2-O-(2-hydroxybutyl)-beta-CD (HB-beta-CD), was successfully synthesized and used as chiral selector in capillary zone electrophoresis. Six chiral drugs, such as anisodamine, ketoconazole, propranolol, promethazine, adrenaline and chlorphenamine enantiomers, belonging to different classes of compounds of pharmaceutical interest were resolved. The chi...

Oxidative stress has been identified as a crucial factor leading to male infertility largely due to peroxidativedamage to the sperm cell membrane. Cadmium (Cd) is a widespread environmental pollutant and oneof the well-known reproductive toxicants. Because of its long biological half-life (10–30 years), Cdaccumulates in the biological systems. The present study was designed to assess the concen...

OBJECTIVE The objective of this study was to explore the differences in upper airway morphology between positional (POSA) and non-positional (NPOSA) obstructive sleep apnea. METHODS This retrospective study enrolled 75 patients (45 NPOSA and 30 POSA) who underwent polysomnography (PSG) and computed tomography (CT). The differences in, and relationships of, the PSG values and CT data between P...

OBJECTIVE The Connor-Davidson Resilience Scale (CD-RISC) measures various aspects of psychological resilience in patients with posttraumatic stress disorder (PTSD) and other psychiatric ailments. This study sought to assess the reliability and validity of the Korean version of the Connor-Davidson Resilience Scale (K-CD-RISC). METHODS In total, 576 participants were enrolled (497 females and 7...

Statistical studies on the correlation analysis and multiple linear stepwise regression analyses based on the different geochemical fractions of metals (Cd, Cu, Pb and Zn) in the sediments of the Straits of Malacca were conducted. Significant (P< 0.001) correlation matrices were found among total concentrations of Cd, Cu, Pb and Zn indicating that they had a common source of anthropogenic origi...
