Poliovirus (PV), the pathogenic agent of paralytic poliomyelitis, is the prototype of the picornavirus family. Although paralytic poliomyelitis has been nearly totally eradicated in most industrialized countries, PV continues to be an important public health problem in many developing countries. Moreover, in industrialized countries, two current concerns are the occurrence, albeit at a very low...

OBJECTIVES/HYPOTHESIS Demonstrate the endoscopic anatomy of the palatovaginal (PV) canal and artery for identification and dissection of the vidian nerve during endoscopic transpterygoid approaches. Evaluate the length of the PV canal and its relation with the vidian nerve. Show that the traditionally known PV canal is a misnomer and should be renamed. STUDY DESIGN Experimental study: anatomi...

We discuss and compare different approaches to calculating the dynamics of anisotropic flow structure formation in quasi two-dimensional turbulence based on potential vorticity (PV) transport in real space. The general structure of the PV flux in the relaxation processes is deduced non-perturbatively. The transport coefficients of the PV flux are then systematically calculated using perturbatio...

A combination of declining costs and policy measures motivated by greenhouse gas (GHG) emissions reduction and energy security have driven rapid growth in the global installed capacity of solar photovoltaics (PV). This paper develops a number of unique data sets, namely the following: calculation of distribution of global capacity factor for PV deployment; meta-analysis of energy consumption in...

Numerous studies have focused on alterations in plasma volume (PV) on interventions like quiet standing, exercise, or heat stress. However, no method seems capable of truly estimating the PV alteration. Therefore, an attempt was made to validate commonly used indexes of PV changes. Quiet standing was used to cause graded PV reductions estimated from hemoglobin and hematocrit (Hb/Hct) and from s...

AIMS Obtaining optimal pulmonary vein (PV) occlusion with the endoscopic laser balloon ablation system (EAS) can be difficult, hypothetically influenced by PV geometry. The aim of this study was to determine the impact of PV orientation on atrial fibrillation (AF)-free survival after PV isolation (PVI) using the EAS. METHODS AND RESULTS Forty-three patients undergoing a single EAS PVI were in...

Polycythemia vera (PV) is characterized by low serum total cholesterol despite its association with vascular events such as myocardial and cerebral infarction. Serum cholesterol level has not been used as a diagnostic criterion for PV since the 2008 revision of the WHO classification. Therefore, we revisited the relationship between serum lipid profile, including total cholesterol level, and er...

BACKGROUND The extent of ostial ablation necessary to electrically disconnect the pulmonary vein (PV) myocardial extensions that initiate atrial fibrillation from the left atrium has not been determined. METHODS AND RESULTS Seventy patients underwent PV mapping with a circumferential 10-electrode catheter during sinus rhythm or left atrial pacing. After assessment of perimetric distribution a...

Post-polycythemia vera myelofibrosis (post-PV MF) is a late evolution of PV. In 647 patients with PV, we found that leukocytosis leukocyte count>(15x10(9)/L) at diagnosis is a risk factor for the evolution of post-PV MF. In a series of 68 patients who developed post-PV MF, median survival was 5.7 years. Hemoglobin level less than 100 g/L (10 g/dL) at diagnosis of post-PV MF was an independent r...

OBJECTIVE To clarify the role of peritoneography in assessing the patency of processus vaginalis (PV) in pediatric patients diagnosed with cryptorchidism. MATERIALS AND METHODS We designed a prospective clinical trial to evaluate the patency of PV in boys presenting cryptorchidism. Herniography was performed in 310 prepubertal boys. Data about the morphology of PV was compared with operative ...
