BACKGROUND/AIMS Doxorubicin (DOX) and trastuzumab (TRA) are associated with cardiac dysfunction. METHOD High-sensitivity troponin T (hs-TnT) and brain natriuretic peptide attached to the amino acid N-terminal fragment in the prohormone (NT-proBNP) were measured before and on days +1, +2, +3, and +7 during cycles 1 and 2 of therapy with DOX or TRA in breast cancer patients. RESULTS Five of e...
درسازه های متداول انرژی ورودی به سازه با ایجاد مفاصل پلاستیک در اعضای فولادی، گسترش ترکها در سازه های بتنی و یا شکست در سازه های بنایی غیرمسلح جذب می شود. این روش جذب انرژی باعث ایجاد تغییر شکل های ماندگار در اعضای باربر ثقلی شده که تخریب کلی سازه یا هزینه ی بسیار بالای تامین دوباره شرایط بهره برداری را به دنبال خواهد داشت. در روش های نوین طراحی لرزه ایی، دو دیدگاه کلی برای مقابله با انرژی ورود...
During the TNT production process, raw product includes about 4.5% of asymmetric TNT isomers. In order to use TNT for military purposes, TNT asymmetric isomers should be removed. Purification of crude TNT is done by selite (15% solution of sodium sulfite). Because of its color, the term red-water is used for this wastewater. Different methods including incineration, microorganisms, conversion o...
This proof-of-concept study proposes a novel sensing mechanism for selective and label-free detection of 2,4,6-trinitrotoluene (TNT). It is realized by surface chemistry functionalization of silica nanoparticles (NPs) with 3-aminopropyl-triethoxysilane (APTES). The primary amine anchored to the surface of the silica nanoparticles (SiO2-NH2) acts as a capturing probe for TNT target binding to fo...
CONTEXT Of the 200 million adults worldwide who undergo noncardiac surgery each year, more than 1 million will die within 30 days. OBJECTIVE To determine the relationship between the peak fourth-generation troponin T (TnT) measurement in the first 3 days after noncardiac surgery and 30-day mortality. DESIGN, SETTING, AND PARTICIPANTS A prospective, international cohort study that enrolled p...
BACKGROUND High-sensitivity troponin I (hs-TnI) and troponin T (hs-TnT) are moderately correlated and independently related to outcome in atrial fibrillation (AF). Rate controlling therapy has been shown to reduce hs-TnT, however the potential impact on hs-TnI levels, and whether this differs from the effects on hs-TnT, has not been investigated previously. METHODS Sixty patients with stable,...
BACKGROUND Elevated level of troponin T (TnT) in the absence of acute coronary syndrome (ACS) can be caused by a number of conditions but the relevance of the chief complaint at admission for TnT level and prognosis has not been reported previously. The aim was to study whether TnT level differs among chief complaints or underlying causes in patients with non-ACS TnT elevation and if these fact...
OBJECTIVES We sought to evaluate C-reactive protein (CRP) and troponin T (TnT) as predictors of risk of the individual end points of mortality and myocardial infarction (MI) in a large cohort of patients with acute coronary syndrome (ACS). BACKGROUND Both CRP and TnT predict risk of future coronary events in patients with ACS. However, the relationships between the levels of the markers and t...
PURPOSE 2,4,6-Trinitrotoluene (TNT) is an explosive used in munitions production that is known to cause both aplastic and hemolytic anemia in exposed workers. Anemia in a TNT worker is considered a sentinel health event (occupational) (SHE(O)) in the United States (US). Deaths have been reported secondary to aplastic anemia. Studies have shown that TNT systemic absorption is significant by both...
