Background Computer-based inline VF software can aid in the quantitative analysis of left ventricular (LV) function. Inline VF automatically locates the LV base and apex, detects endoand epicardial contours in each cardiac slice and phase, and performs a volumetric calculation to determine ejection fraction (EF), end-diastolic volume (EDV), end-systolic volume (ESV). The method presents an oppo...

PURPOSE Therapeutic prostate-specific antigen (PSA) -targeted poxviral vaccines for prostate cancer have been well tolerated. PROSTVAC-VF treatment was evaluated for safety and for prolongation of progression-free survival (PFS) and overall survival (OS) in a randomized, controlled, and blinded phase II study. PATIENTS AND METHODS In total, 125 patients were randomly assigned in a multicenter...

BACKGROUND There are limited data from resource-limited settings on antiretroviral resistance mutations that develop in patients failing second-line PI ART. METHODS We performed a cross-sectional virological assessment of adults on second-line ART for ≥6 months between November 2006 and December 2011, followed by a prospective follow-up over 2 years of patients with virological failure (VF) a...

OBJECTIVE To assess the use of Prothrombinex-VF powder for injection (PTX-VF) at Royal Perth Hospital and analyse the efficacy and safety profile of PTX-VF. DESIGN, SETTING AND PATIENTS A prospective observational audit of PTX-VF use, conducted by reviewing medical records and laboratory and imaging results for all patients prescribed PTX-VF from 1 November 2009 to 1 May 2010. MAIN OUTCOME ...

CONTEXT Visfatin (VF) is a recently described adipokine preferentially secreted by visceral adipose tissue (VAT) with insulin mimetic properties. OBJECTIVE The aim of this study was to examine the association of VF with insulin sensitivity, intramyocellular lipids (IMCL), and inflammation in humans. DESIGN AND PATIENTS VF mRNA was examined in paired samples of VAT and abdominal sc adipose t...

the aim of this study is to evaluate how far lempel-ziv complexity (lzc) of the binary symbolic sequences resulting from static or dynamic transformation (partitioning first-order difference) of the short-term electrocardiogram (ecg) signals (only 2 seconds duration) has the  potential in discriminating normal and ventricular tachycardia/ventricular fibrillation (vt/vf) subjects. the statistica...

Ventricular tachycardia and fibrillation (VT/VF) are the leading, immediate causes of death in the developed world. Investigation of the mechanisms of VT/VF spans over a century and a half. However, despite a long and exciting history of discovery in the field, we are still asking the same questions posed by Carl J. Wiggers in 1940 [1]: ‘‘As to the fundamental mechanisms of fibrillation we have...

PURPOSE We developed a statistical model to improve the detection of glaucomatous visual field (VF) progression as defined by the consensus of expert clinicians. METHODS We developed new methodology in the Bayesian setting to properly model the progression status of a patient (as determined by a group of expert clinicians) as a function of changes in spatially correlated sensitivities at each...

Using a long, flexible test cable connected with a one-wire voltage feedback circuit, a resistive tactile sensor in a shared row-column fashion exhibited flexibility in robotic operations but suffered from crosstalk caused by the connected cable due to its wire resistances and its contacted resistances. Firstly, we designed a new non-scanned driving-electrode (VF-NSDE) circuit using two wires f...

Abstract Introduction Few studies evaluated risk factors for primary ventricular fibrillation (VF) before reperfusion during a first acute myocardial infarction (AMI). Important parameters such as kalemia, blood pressure (BP) and heart rate (HR) at presentation were rarely considered. Furthermore, potential differences according to the time elapsed between symptoms onset VF have never been inve...
