Cardiac troponin T (cTnT) and troponin I (cTnI) have been suggested as new, more specific markers of myocardial cellular damage. The objective of this study was to examine how the distributions of cTnI and cTnT were affected in postinfarction left ventricular remodeled (LVR) myocardium. At 2 months postinfarct in a porcine heart failure model, both Western blot and biochemical assay analyses we...

The mechanism of the pressor response to small muscle mass (e.g., forearm) exercise and during metaboreflex activation may include elevations in cardiac output (Q) or total peripheral resistance (TPR). Increases in Q must be supported by reductions in visceral venous volume to sustain venous return as heart rate (HR) increases. Therefore, this study tested the hypothesis that increases in Q, su...

UNLABELLED Lung volume reduction (LVR) is an effective therapy for end-stage emphysema. Preliminary and postprocedure imaging is usually limited to CT for anatomic delineation of the location and severity of the most acutely affected lung zones. The purpose of this study was to investigate the potential of using a new quantitative gas trapping index (GTI) derived from a (133)Xe ventilation scan...

Analog design is an inherently intricate process comprising many trade-offs; as a result, it iterative time-consuming operation. A low dropout voltage regulator (LDO) example of such analog blocks that involve myriad trade-offs. In this paper, we present automated procedure for LDOs using precomputed look-up tables (LUTs) and the gm/ID methodology. Using symbolic solver LUTs, database LDO conta...
