TA-3037A, a new inhibitor of glutathione S-transferase, has been isolated from the culture broth of Streptomyces sp. TA-3037. The structure of TA-3037A was defined as (Z)-3-benzylidene-3,4-dihydro-2-oxo-2H-1,4-benzoxazine-5-carboxylic acid by an analysis of spectral properties and chemical studies of TA-3037A and its derivatives.

Although analysis of toxin-antitoxin (TA) systems can be instructive, to date, there is no information on the prevalence and identity of TA systems based on a large panel of Acinetobacter baumannii clinical isolates. The aim of the current study was to screen for functional TA systems among clinical isolates of A. baumannii and to identify the systems' locations. For this purpose, we screened 8...

INTRODUCTION AND OBJECTIVES The benefit of manual thrombus aspiration (TA) in the reperfusion of patients with ST-elevation myocardial infarction (STEMI) has been hotly debated. In most series, failure of TA has been largely unreported. Our objectives were to assess the rate, predictors, and impact on cumulative mortality of failed TA during primary percutaneous coronary intervention (PPCI). ...
