INTRODUCTION Over the last 15 years, virtual reality (VR) has emerged as an innovative tool for addressing numerous issues in clinical research, assessment, and intervention. Technological advances in the areas of computation speed and power, graphics and image rendering, display systems, tracking, interface technology, haptic devices, authoring software and artificial intelligence have support...

The first 84 nt in the 3' non-translated region (3' NTR) of dengue type 1 virus (DENV-1) exhibit lower levels of conservation than the other regions; this region is named the variable region (VR). The VR is further divided into two subregions: a 5'-terminal hypervariable region (HVR) and a 3'-terminal semi-variable region (SVR). Recent reports suggested that the VR of DENV-2 is required for eff...

BACKGROUND Returning to work (RTW) in the UK is problematic following TBI. Vocational rehabilitation (VR) is limited and efficacy or costs seldom reported. This study aimed to determine whether a TBI specialist VR intervention (TBI VR) was more effective at work return and retention 12 months after injury than usual care (UC). Secondary aims were to explore the feasibility of collecting economi...

OBJECTIVES With the recent emergence of vancomycin-resistant (VR) Staphylococcus aureus, subsequent to the suggested transfer of the vanA resistance gene from Enterococcus faecalis, we sought to determine risk factors for acquisition of VR E. faecalis and to evaluate the molecular epidemiology of this less-prevalent and less-studied species of VR enterococcus. METHODS We compared clinical iso...

BACKGROUND Peripheral nerves at the elbow region are prone to entrapment neuropathies and injuries. To make accurate assessment, clinicians need stereoscopic display of the nerves to observe them at all angles. OBJECTIVES To obtain a stereoscopic display of the peripheral nerves at the elbow region based on magnetic resonance (MR) diffusion tensor imaging (DTI) data using three post-processin...

Source parameter scaling for major and great thrust-faulting events on circum-Pacific megathrusts is examined using uniformly processed finite-fault inversions and radiated energy estimates for 114 Mw≥ 7.0 earthquakes. To address the limited resolution of source spatial extent and rupture expansion velocity (Vr) from teleseismic observations, the events are subdivided into either group 1 (18 ev...

21 Objective: Cardiotonic agents may differentially alter indices of the cytosolic [Ca ] / left ventricular pressure (LVP) relationship when 21 given before and after ischemia. We measured and calculated systolic–diastolic [Ca ], systolic–diastolic LVP, velocity ratios (VRs) 21 21 21 d[Ca ] /dt to dLVP/dt (VR ), d[Ca ] /dt to dLVP/dt (VR ), and area ratio (AR, area Ca ] /area LVP per beat) befo...

OBJECTIVES We compared the effects of five pharmacologic regimens on the circadian rhythm and exercise-induced changes of ventricular rate (VR) in patients with chronic atrial fibrillation (CAF). BACKGROUND Systematic comparison of standardized drug regimens on 24 h VR control in CAF have not been reported. METHODS In 12 patients (11 male, 69+/-6 yr) with CAF, the effects on VR by 5 standar...

Virtual reality (VR) has made its way into mainstream psychological research in the last two decades. This technology, with its unique ability to simulate complex, real situations and contexts, offers researchers unprecedented opportunities to investigate human behavior in well controlled designs in the laboratory. One important application of VR is the investigation of pathological processes i...

BACKGROUND AND OBJECTIVES It has been demonstrated that the neutrophil/lymphocyte ratio (NLR) might be a useful marker to predict cardiovascular risk and events. We aimed to investigate the role of the NLR to predict ventricular remodeling (VR) in patients with anterior ST-elevation myocardial infarction (STEMI) who were treated with primary percutaneous coronary intervention. SUBJECTS AND ME...
