BACKGROUND In this retrospective study, approximately 440 patients received mitral valve replacements with the St Jude Medical prosthesis. The last patient was operated on 10 years before the beginning of the follow-up. The extended follow-up was 19 years. METHODS AND RESULTS Four hundred forty patients (sex ratio, 1.32 [men to women]; age, 60+/-11.4 years; age range, 7 to 75 years) were oper...

PURPOSE An-organic bovine bone graft is a xenograft with the potential of bone formation. The aim of this study was to evaluate the bone density using cone beam computed tomography scans around functional endosseous implant in the region of both augmented maxillary sinus with the an-organic bovine bone graft and the alveolar bone over which the graft was placed to provide space for the implants...

Four families from the same region of Cambodia immigrated to the Pacific Northwest of the United States. All four families have been discovered to have spinocerebellar ataxia type 3 (SCA 3; Machado-Joseph disease) with a similar clinical phenotype. CAG repeat expansions in the ATXN3 gene range from 72 to 77. Mean age of onset has varied from 19 to 44 years and mean age at death of 4 individuals...

Background Levels of serum gonadotropins have direct effects on testicular functions and spermatogenesis. Assessment of levels of serum gonadotropins from fathered subjects and infertile patients indicates wide range diversity. In this study, we tried to find out whether the levels of seminal FSH and LH affect the parameters of seminal fluid analysis (SFA) and if there is any correlation betwee...

purpose : to compare retinal nerve fiber layer (rnfl) profile in subjects with myopia and emmetropia using gdx variable corneal compensator (vcc) methods : besides ophthalmologic standard examination (refraction, visual acuity and slit-lamp examination, applanation tonometry, and funduscopy), perimetry and scanning laser polarimetry (slp) were performed. 171 healthy age-matched subjects with lo...

AIM To assess the prevalence of active and inactive uveitis unrelated to previous surgery or trauma in an urban population in southern India. METHODS As part of the Andhra Pradesh Eye Disease Study, 2522 subjects (85.4% of those eligible), a sample representative of the population of Hyderabad city in southern India, underwent interview and detailed dilated eye examination. Presence of sequel...

PURPOSE To analyze the maximum axial force, the mean axial force, the amount of energy accumulated by the tongue, and the time taken to reach the maximum axial force, in different age ranges. METHODS The records of 92 individuals - students, staff and visitors at an university -, 29 (32.6%) men and 63 (67.4%) women, with ages between 14 and 53 years old, were analyzed. Subjects were divided i...

Drug clearance is often higher in children than in adults, particularly when normalized to body weight. We previously showed that liver volume normalized to body weight was inversely related to age, but that the systemic clearance of a nonspecific cytochrome P450 (CYP) substrate (antipyrine) was higher in young children compared with adults even when normalized per liver volume. Our purpose her...

Context : Range of motion (ROM) in the glenohumeral joint decreases with age healthy subjects; however, underlying mechanism remains unclear. The process aging capsule, including coracohumeral ligament (CHL), could affect ROM limitation. Objective This study investigated correlations between elasticity CHL, evaluated by means shear-wave elastography, and age, side dominance, individuals. Design...
