This study examined high-energy phosphates (HEP) and mitochondrial ATPase protein expression in hearts in which myocardial infarction resulted in either compensated left ventricular remodeling (LVR) or congestive heart failure (CHF). The response of HEP (measured via (31)P magnetic resonance spectroscopy) to a modest increase in the cardiac work state produced by dobutamine-dopamine infusion an...

Blood osmolality rises during general muscle exercise. The purpose of this work was to investigate the effect of similar slow, graded rises of blood osmolality on pulmonary vascular resistance. Hyperosmolar solutions of sodium chloride, mannitol, urea, glucose, thiourea and ethylene glycol were infused into the left lower lobe pulmonary arterial branch in the cat. Lobe blood flow, pulmonary art...

The purpose of this study was to determine whether the human diaphragm, like limb muscle, has a threshold of force output at which a metaboreflex is activated causing systemic vasoconstriction. We used Doppler ultrasound techniques to quantify leg blood flow (Q(L)) and utilized the changes in mouth twitch pressure (DeltaP(M)T) in response to bilateral phrenic nerve stimulation to quantify the o...

Objectives: [1] To review our experience with left ventricular reconstruction (LVR) regarding safety (early mortality and morbidity) and long-term survival (Study I). [2] To evaluate LVR including surgery for ventricular tachycardia in patients with preoperative spontaneous or inducible ventricular tachycardia (Study II). [3] To analyze risk factors for mortality and hospital re-admission for h...

In a traditional registration of a single aerial image with airborne light detection and ranging (LiDAR) data using linear features that regard line direction as a control or linear features as constraints in the solution, lacking the constraint of linear position leads to the error propagation of the adjustment model. To solve this problem, this paper presents a line vector-based registration ...

INTRODUCTION Left ventricular remodeling (LVR) is the most prognostically important consequence of acute myocardial infarction (AMI). The aim of the study was to assess the value of speckle tracking echocardiography in the prediction of left ventricular remodeling in patients after AMI and primary coronary angioplasty (PCI). MATERIAL AND METHODS Eighty-eight patients (F/M = 31/57 patients; 63...

In the automotive domain, vast majority of testing is performed through simulations, which can validate a system design before actual implementation and emphasize eventual faults in process. Hence, simulation utmost importance. Behavioral models are necessary for creation each electronic device desired system, some components have very complex behavior: low-dropout linear voltage regulators (LD...

This document describes the advantages of modern switching voltage regulators in a power distribution network (PDN) design to achieve the best FPGA transceiver performance. This white paper provides guidance on voltage regulator selection for low-noise applications, and a test case that demonstrates the transceiver performance for different types of voltage regulators and voltage rail configura...
