BACKGROUND Panton-Valentine leucocidin is a Staphylococcus aureus virulence factor encoded by lukF-PV and lukS-PV that is infrequent in S aureus bacteremia (SAB), and, therefore, little is known about risk factors and outcome of lukF-PV/lukS-PV-positive SAB. METHODS This report is a register-based nationwide observational cohort study. lukF-PV was detected by polymerase chain reaction. Factor...

INTRODUCTION There are currently no studies systematically evaluating pulmonary vein (PV) stenosis following catheter ablation of atrial fibrillation (AF) using the anatomic PV ablation approach. METHODS AND RESULTS Forty-one patients with AF underwent anatomic PV ablation under the guidance of a three-dimensional electroanatomic mapping system. Gadolinium-enhanced magnetic resonance (MR) ima...

Recent studies indicate that the basolateral amygdala exhibits fast rhythmic oscillations during emotional arousal, but the neuronal mechanisms underlying this activity are not known. Similar oscillations in the cerebral cortex are generated by a network of parvalbumin (PV)-immunoreactive interneurons interconnected by chemical synapses and dendritic gap junctions. The present immunoelectron mi...

it to 680•Ž in flowing nitrogen (PV-7). Four samples having different pre-heat-treatment conditions were selected; the original coke PV-7 , the second one prepared from PV-7 by the heat treatment at 1500•Ž for 60 min (PV-15) , the third also from PV-7 by the treatment at 2060•Ž for 60 min (PV-7-20) , and the fourth by the heat treatment of PV-15 at 2060•Ž for 60 min (PV-15-20). Each sample was ...

BACKGROUND The relationship between pulmonary vein (PV) anatomy and successful catheter ablation of atrial fibrillation (AF) is poorly understood METHODS First-pass contrast enhanced PV magnetic resonance angiography was performed in 71 consecutive patients prior to PV isolation. PV diameter and cross-sectional area (CSA) were measured prior to PV isolation. Any symptomatic or asymptomatic AF...

With growth of PV market in tropical region, it is necessary to investigate the performance of different types of PV technology under the tropical weather conditions. Singapore Polytechnic was funded by Economic Development Board (EDB) to set up a solar PV test-bed for the research on performance of different types of PV modules in the country. The PV test-bed installed the nine different types...

The cerebellar cortex has a fundamental parasagittal organization that is reflected in the physiological responses of Purkinje cells, afferent and efferent connections, and the expression of several molecular markers. The most thoroughly studied of these molecular markers is zebrin II (ZII; a.k.a. aldolase C). ZII is differentially expressed in Purkinje cells, resulting in a pattern of sagittal...

BACKGROUND & OBJECTIVES Acute renal failure (ARF) is a known manifestation of severe Plasmodium falciparum (Pf) malaria but recently it has also been observed with P. vivax (Pv) monoinfection. A clinical observational study has been conducted to evaluate the clinical and histopathological profile of ARF in malaria. METHODS This study was conducted on 288 consecutive cases of malaria with mono...

The inability of papillomaviruses (PV) to replicate in tissue culture cells has hampered the study of the PV life cycle. We investigated virus-cell interactions by the following two methods: (i) using purified bovine PV virions or human PV type 11 (HPV type 11) virus-like particles (VLP) to test the binding to eukaryotic cells and (ii) using different VLP-reporter plasmid complexes of HPV6b, HP...

Pulmonary vein (PV) stenosis has emerged recently as an important issue in patients who received radiofrequency (RF) ablation of atrial fibrillation (AF). Serial pathophysiological responses, including thrombosis, metaplasia, proliferation and neovascularization, may lead to PV stenosis after RF energy application around or inside the PV ostia. The clinical manifestations of PV stenosis consist...
