Effectiveness of Focused Obstetric Ultrasound Training to Nurses from Remote Health Posts to Improve Pregnancy Outcome and Reduce Morbidity.

Background: A rural ultrasound program was started in Nepal in order to detect complicated pregnancies early in health post where radiologists are not available to provide their services. The study aims to investigate whether focused obstetric ultrasound trained nurses were capable of detecting high risk pregnancy at an early stage in their health post and refer them to higher centre timely so that they are taken care properly.

Methods: The study site for research were health posts and hospitals where the rural ultrasound program had been conducted in districts of Sudurpashchim province.

Tethered domains and flexible regions in tRNase Z(L), the long form of tRNase Z.

tRNase Z, a member of the metallo-β-lactamase family, endonucleolytically removes the pre-tRNA 3' trailer in a step central to tRNA maturation. The short form (tRNase Z(S)) is the only one found in bacteria and archaebacteria and is also present in some eukaryotes. The homologous long form (tRNase Z(L)), exclusively found in eukaryotes, consists of related amino- and carboxy-domains, suggesting that tRNase Z(L) arose from a tandem duplication of tRNase Z(S) followed by interdependent divergence of the domains.
