Human steroid sulfatase (STS) plays an important role in regulating the formation of biologically active estrogens and may be a promising target for treating estrogen-mediated carcinogenesis. The molecular mechanism of STS gene expression, however, is still not clear. Growth factors are known to increase STS activity but the changes in STS expression have not been completely understood. To dete...

BACKGROUND: The purpose of this study was to localize the expression of steroid sulfatase (STS) in cumulus cells and to determine the relationship between STS mRNA expression and the serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol and progesterone. METHODS: The subject group included 49 women (29 to 44 years old) for whom in vitro fertilization treatment ...

This article describes a quality improvement project in which early skin-to-skin (STS) contact, in the operating room (OR) and during recovery, was used as an intervention to increase the success of breastfeeding initiation among healthy infants after cesarean, at a large, urban, acute care teaching hospital. The nursing role is key for the intervention, but the program involves the entire peri...

Most epidemiological studies of soft tissue sarcoma (STS) were performed in the Western countries, and only limited data highlighting that in the Asian population. The aim of this study is to conduct a comprehensive analysis for the incidence rates of STS in Taiwan.This was a population-based study analyzing the incidence rates and trends of the primary STS over extremities and trunk wall durin...

Sts (suppressor of T-cell receptor signalling)-1 and Sts-2 are HPs (histidine phosphatases) that negatively regulate TCR (T-cell receptor) signalling pathways, including those involved in cytokine production. HPs play key roles in such varied biological processes as metabolism, development and intracellular signalling. They differ considerably in their primary sequence and substrate specificity...

BACKGROUND AND PURPOSE The ability to rise from a chair is important for independence in everyday life. This study was conducted to determine to what extent knee extension force (KEF) could explain independence in sit-to-stand (STS) performance from a standard chair. SUBJECTS AND METHODS This was a descriptive and correlational study of patients receiving acute rehabilitation (N=107). Measure...

This paper estimates the effect of ambulatory surgical centers (ASCs) on hospital surgical volume using hospital and year fixed effects models with several robustness checks. We show that ASC entry only appears to influence a hospital's outpatient surgical volume if the facilities are within a few miles of each other. Even then, the average reduction in hospital volume is only 2-4%, which is no...

A rovibrationally state-specific collision model for the O2(Σg−3)+O(P3) system is presented direct simulation Monte Carlo, including rotation–vibration–translation energy transfer, exchange, dissociation, and recombination processes. The two-step binary approach employed to reactions. Two available cross section databases by Andrienko/Boyd Esposito/Capitelli are resolved (rv-STS) vibrationally ...
