Musicians are able to create different expressive performances of the same piece of music by varying expressive features. It is challenging to mathematically model and represent musical expressivity in a general manner. Vibrato and portamento are two important expressive features in singing, as well as in string, woodwind, and brass instrumental playing. We present AVA, an off-line system for a...

INTRODUCTION Traditional genotyping assays detect viral variants present in at least 15-25% of the entire virus population. We tested the Next generation GS Junior System (NGS) setted with a detection limit of 0.05% and evaluated the clinical relevance of low prevalent mutations. METHODS NGS was performed on the plasma of 26 infected individuals who started a TDF/FTC/RPV (15 subjects) or TDF/...

History. We report about the course of central sleep apnea (CSA) in 3 patients (70.3 +/- 15.2 years) with severe aortic stenosis (AS) (AVA </= 1.0 cm(2), NYHA 2.7 +/- 1.4). Investigations. Every patient received echocardiography, left/right-heart catheterization, and cardiorespiratory polygraphy before and 6 months after surgical aortic valve replacement (without right-heart catheterization dur...

BACKGROUND Adult calcific aortic stenosis is a well-known clinical entity but its pathophysiology and cellular mechanism have yet to be defined. OBJECTIVES To determine whether there is an association between the presence and severity of adult calcific aortic stenosis and Chlamydia pneumoniae seropositivity. METHODS Forty adult patients (23 women, 17 men) were divided into three groups acco...

PURPOSE To investigate tumor necrosis factor (TNF)-α gene polymorphisms in advanced dry-type age-related macular degeneration (AMD) in a population from Northeastern Iran. METHODS In this case-control study, 50 patients with geographic macular atrophy and 73 gender-matched controls were enrolled. Genomic deoxyribonucleic acid (DNA) was extracted from the peripheral blood. Polymerase chain rea...

Bacillus anthracis are aerobic or facultatively anaerobic Gram-positive, nonmotile rods measuring 1.0 μm wide by 3.0–5.0 μm long. Under adverse conditions, B. anthracis form highly resistant endospores (Figure 1). These are found in soil at sites where infected animals previously died. Interest in the pathogenesis, immunity, and vaccine development for anthrax was heightened by the deliberate c...

Observation: Primary anetoderma is very uncommon in childhood. The exact pathogenesis and curative treatment of anetoderma are still unknown. We report a 12 -year-old girl presented with multiple elevated or herniated, circumscribed, skin-coloured papules which initially emerged as erythematous macules over her neck, trunk, upper and lower extremities. Histopathological examination of a papular...

Purpose. To report a case report of one patient suffering from retinal artery occlusion secondary to Buerger's disease, in order to raise awareness to this etiology in the differential diagnosis of retinal artery occlusion. Methods. A retrospective case report of a patient with retinal artery occlusion secondary to Buerger's disease. Data retrieved from the medical records included exposure, co...

The aim of this study is to propose a experimental verification for single-phase to three phase drive system composed of two parallel single-phase rectifiers, a three-phase inverter and an induction motor. Apart from traditional application in dc motor drives, new applications of BDC include energy storage in renewable energy systems, fuel cell energy systems, Hybrid Electric Vehicles (HEV) and...

BACKGROUND Aortic valve area (AVA) in aortic stenosis (AS) can be assessed noninvasively or invasively, typically with similar results. These techniques have not been validated in elderly patients, where common assumptions make them most prone to error. Accurate assessment of AVA is crucial to determine which patients are appropriate candidates for aortic valve replacement. METHODS AND RESULT...
