Background: The Centers for Medicaid and Medicare Services approved a number of panels as screening tests including those for liver functions. The utility of routinely testing for Aspartate aminotransferase (AST) and direct bilirubin was questioned and empirical data analyzed to suggest alternatives. Methods: Tests done over six months were examined for AST, ALT, total and direct bilirubin valu...
Rat liver cytosolic sulfotransferase activity forms the highly reactive sulfuric acid ester of N-hydroxy-2-acetylaminofluorene (N-OH-2AAF), an ultimate carcinogen in 2-acetylaminofluorene (2AAF) hepatocarcinogenesis. A previous report demonstrated that 2AAF-induced liver hyperplastic nodules displayed a persistent loss of cytosolic N-OH-2AAF sulfotransferase activity following a hepatocarcinoge...
OBJECTIVES Previous research consistently indicates that children who engage in active school transport (AST) are more active than their peers who use motorized modes (car or bus). However, studies of the correlates of AST have been conducted predominantly in high-income countries and have yielded mixed findings. Using data from a heterogeneous sample of 12 country sites across the world, we in...
Aspartate aminotransaminase (AST) is a hepatocelluar enzyme released into the bloodstream when hepatic cells are damaged, resulting in elevated blood levels of AST. A single use, disposable biosensor prototype, composed of catalytic iridium nano-particles dispersed on carbon paste, was developed to detect enzymatically-produced H2O2 in AST-mediated reactions. This biosensor is capable of measur...
OBJECTIVES This study sought to determine clinical, procedural, and treatment factors associated with acute stent thrombosis (AST) in the EUROMAX (European Ambulance Acute Coronary Syndrome Angiography) trial. BACKGROUND Bivalirudin started during transport for primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction significantly reduced major bleeding ...
INTRODUCTION Despite major advances in stent technology and antithrombotic therapy, the development of stent thrombosis continues to be a major problem in patients who have undergone percutaneous coronary intervention (PCI). Although a few studies have investigated the relationship between early stent thrombosis and platelet activity, the relationship between acute stent thrombosis (AST) (withi...
The oral adsorbent AST-120 is composed of spherical carbon particles and has an adsorption ability for certain small-molecular-weight compounds that accumulate in patients with chronic kidney disease (CKD). So far, very few compounds are known to be adsorbed by AST-120 in vivo. To examine the effect of AST-120 in vivo, we comprehensively evaluated the plasma concentrations of 146 compounds (61 ...
فرض کنید $r$ حلقه ی تعویض پذیر, یکدار و $m$ یک $r$-مدول یکانی است. مدول $m$ را مدول ضربی می نامند, هرگاه برای هر زیرمدول $n$ از مدول $m$ ایده آل $i$ از حلقه ی $r$ وجود داشته باشد به طوری که $mi=n$. در این پایان نامه برای $r$-مدول ضربی $m$ حلقه ی $m^{ast}$ شامل درون ریختی های $m$ بررسی می شود. رابطه بین زیرمدول های اول(ماکسیمال) از مدول $m$ ...
