BACKGROUND Environmental pollutant exposure may play certain roles in the pathogenesis and progression of diabetes mellitus including gestational diabetes mellitus (GDM). We hypothesize that heavy metal exposure may trigger GDM during pregnancy. The objective of this study was to investigate the possible associations between selected heavy metal exposure and GDM risk. METHODS This investigati...

Transversus abdominal plane (TAP) block has a long history and there is currently extensive clinical experience around TAP blocks. The aim of this review is to provide a summary of the present evidence on the effects of TAP block and to provide suggestions for further studies. There are several approaches to performing abdominal wall blocks, with the rapid implementation of ultrasound-guided te...

While the risk of transmission through oral sex for men who have sex with men (MSM) is low, discrepancies remain between study findings and there is uncertainty about the exact degree of risk. Between July 2001 and September 2003, a total of 4150 MSM were newly diagnosed with HIV infection in England, Wales, and Northern Ireland and reported to the Communicable Disease Surveillance Centre in Lo...

2014 Dielectric spectra of Rb2ZnCl4 were determined in the 6-400 cm-1 region for 300 and 90 K. In the 30-400 cm-1 region they were evaluated from bulk reflectivity measurements, in the 6-22 cm-1 region they were calculated from complex transmittance measurements performed on a tunable monochromatic BWO spectrometer. All polar modes were approximately assigned and their parameters determined. No...
