OBJECTIVES The traditional risk score (RAMA-EGAT) has been shown to be an accurate scoring system for predicting coronary artery disease (CAD). Arterial stiffness measured by the cardio-ankle vascular index (CAVI) is known to be a marker of atherosclerotic burden. A study was undertaken to determine whether CAVI improves the prediction of CAD beyond the RAMA-EGAT score. DESIGN Cross-sectional...

This paper analyzed three middle grade novels and a short story from two cultures using the journey motif as the vehicle for the analysis. The three novels are Bud Not Buddy and The Watsons Go to Birmingham both by Paul Curtis   and Journey to Jo’burg by Naidoo (1986). The short story is My Two Dads by M. Lee.  The three novels and a short story were chosen because these no...

A robust adaptive microphone array (RAMA) using a new adaptationmode control method (AMC) is proposed, and its evaluation results by hardware are presented. The adaptation of the RAMA is controlled based on an SNR (signal-to-noise) estimate using the output powers of the fixed beamformer and the adaptive blocking matrix. The RAMA is implemented on a multi-DSP realtime signalprocessing system wi...

Multidrug resistance (MDR) in Enterobacter aerogenes can be mediated by induction of MarA, which is triggered by certain antibiotics and phenolic compounds. In this study, we identified the gene encoding RamA, a 113-amino-acid regulatory protein belonging to the AraC-XylS transcriptional activator family, in the Enterobacter aerogenes ATCC 13048 type strain and in a clinical multiresistant isol...

A series of cell lines was isolated from the metastasizing rat mammary tumor cell strain TMT-081. MS by single-cell cloning. Feeder cells were required for development of single tumor cells into clonal colonies. The rate, pattern, and incidence of metastases following injection of cells into the mammary fat pads of syngeneic rats were relatively similar for the various cell lines, with dissemin...

Of 26 tigecycline-nonsusceptible Klebsiella pneumoniae (TNSKP) clinical isolates, 25 had nonsynonymous mutations in ramR and/or acrR (23 in ramR and 10 in acrR). Eight TNSKP isolates possessed overexpression of ramA, acrB, rarA, and oqxB simultaneously, while 8 and 1 TNSKP strains had upregulation of ramA and acrB and of rarA and oqxB, respectively. Thus, resistance mechanisms of 9 TNSKP isolat...

OBJECTIVES salmonella enterica strains exhibiting decreased susceptibility to tigecycline have been reported. In this study, we sought to elucidate the roles of Salmonella multidrug efflux pumps and AcrAB regulators in tigecycline resistance. METHODS we examined the involvement of multidrug efflux pumps and AcrAB regulators in resistance to tigecycline and other glycylcyclines by determining ...
