In soft tissue sarcomas (STS), low intratumoural O2 (hypoxia) is a poor prognostic indicator. HIF-1α mediates key transcriptional responses to hypoxia, and promotes STS metastasis; however, the role of the related HIF-2α protein is unknown. Surprisingly, here we show that HIF-2α inhibits high-grade STS cell growth in vivo, as loss of HIF-2α promotes sarcoma proliferation and increases calcium a...

Nano erythrocyte ghosts have recently been used as drug carriers of water-soluble APIs due to inherit biological characteristics of good compatibility, low toxicity, and small side-effect. In this study, we developed a novel drug delivery system based on nano erythrocyte ghosts (STS-Nano-RBCs) to transport Sodium Tanshinone IIA sulfonate (STS) for intravenous use in rat. STS-Nano-RBCs were prep...

Anti-apoptotic properties of physiological and elevated levels of the cellular prion protein (PrPc) under stress conditions are well documented. Yet, detrimental effects of elevated PrPc levels under stress conditions, such as exposure to staurosporine (STS) have also been described. In the present study, we focused on discerning early apoptotic STS-induced proteome and phospho-proteome changes...

BACKGROUND AND OBJECTIVES Vascular calcification is a major cause of morbidity and mortality in dialysis patients. Human and animal studies indicate that sodium thiosulfate (STS) may prevent the progression of vascular calcifications. The pharmacokinetics of STS in hemodialysis patients has not been investigated yet. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS STS was given intravenously to...

PURPOSE The aim of the study was to determine steroid sulfatase (STS) expression in endometrial cancer patients and its correlation with disease prognosis. MATERIALS AND METHODS We conducted a retrospective study in 59 patients who underwent surgery with histologically confirmed endometrial cancer from January 2000 to December 2011 at Hanyang University Hospital. Immuno-histochemical staining...

STS-Tool is the modelling and analysis support tool for STSml, our proposed actorand goal-oriented security requirements modelling language for Socio-Technical Systems (STSs). STS-Tool allows designers to model an STS through high-level primitives, to express security constraints over the interactions between the actors in the STS, as well as to derive security requirements once the modelling i...

Our research assessed the prevalence of secondary traumatic stress (STS) among mental health providers working with military patients. We also investigated personal, work-related, and exposure-related correlates of STS. Finally, using meta-analysis, the mean level of STS symptoms in this population was compared with the mean level of these symptoms in other groups. Participants (N = 224) comple...

University degree programs in STS (Science and Technology Studies) represent a popular training ground for scholars and other professions dealing with advanced studies in science and technology. Degree programs in STS are currently offered at universities around the globe with various specializations and orientations. This study explores the nature of science and technology in Canada and the st...

Medical knowledge in clinical practice guideline (GL) texts is the source of task-based computer-interpretable clinical guideline models (CIGMs). We have used Unified Medical Language System (UMLS) semantic types (STs) to understand the percentage of GL text which belongs to a particular ST. We also use UMLS semantic network together with the CIGM-specific ontology to derive a semantic meaning ...
