The main aim of this study was to review and compile the results of studies conducted on strains and lineages of M. tuberculosis in Ethiopia. METHODS A systematic search and review ...

Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducted states on their edge or surface. These states are possible due to the combination of spinorbit interactions and time-reversal symmetry. The two-dimensional (2D) topological insulator is a quantum spin Hall insulator, which is a close cousin of the integer quantum Hal...

Temporal- and dose-dependent changes in hepatic gene expression were examined in immature ovariectomized C57BL/6 mice gavaged with ethynyl estradiol (EE), an orally active estrogen. For temporal analysis, mice were gavaged every 24 h for 3 days with 100 microg/kg EE or vehicle and liver samples were collected at 2, 4, 8, 12, 24 and 72 h. Gene expression was monitored using custom cDNA microarra...

OBJECTIVE The objective of the study was to evaluate the impact of group prenatal care (GPNC) on postpartum family-planning utilization. STUDY DESIGN A retrospective cohort of women continuously enrolled in Medicaid for 12 months (n = 3637) was used to examine differences in postpartum family-planning service utilization among women participating in GPNC (n = 570) and those receiving individu...

BACKGROUND After percutaneous coronary intervention patients with diabetes mellitus are under higher risk of death, restenosis and stent thrombosis (ST) compared to non-d...

The levels of a number of ribosomal protein mRNAs are reported to be increased in human colon cancer. We have assessed whether selected ribosomal protein mRNAs are overexpressed in other gastrointestinal malignancies, namely gastric and hepatocellular carcinomas. Subtracted complementary DNA libraries were generated from paired samples of human (a) coloréela!carcinoma minus adjacent normal col...

Background Expert consensus statements on management of implantable cardioverter defibrillators (ICDs) emphasize the importance of having discussions about deactivation before and after implantation. These statements were developed with limited patient input. The purpose of this study was to identify the factors associated with patients' experiences of end-of-life discussions, attitudes towards...

introduction: reverse osmosis (ro) is best known for its use in desalination (removing the salt from seawater to get fresh water), but since the early 1970s it has also been used to purify fresh water for medical, industrial, and domestic applications. the aim of this research was the performance study of reverse osmosis plants for water desalination in bandar-lengeh, iran. materials and method...
