BACKGROUND As mitral valve (MV) repair for Barlow's disease remains surgically challenging, it is important to distinguish Barlow's disease from fibroelastic deficiency (FED) preoperatively. We hypothesized that the prolapse volume to prolapse height ratio (PV-PH ratio) may be useful to differentiate Barlow's disease and FED.Methods and Results:In 76 patients with MV prolapse who underwent pres...

The original diagnostic 24 hour pH monitoring data in 57 children with gastro-oesophageal reflux (GOR) were retrospectively reviewed after a minimum of one year follow up. The tracings of children who responded to medical treatment were compared with those who failed to respond and required a fundoplication. Children with GOR secondary to oesophageal atresia/tracheo-oesophageal fistula and neur...

a 57-year-old woman was referred with chief complaint of pallor and lethargy for 9 months. laboratory investigation was notable for anemia and occult blood in the stool exam. her past medical history was unremarkable. endoscopy of the upper gastrointestinal tract showed a large fungative reddish mass measuring 7 x 6 cm in the body of the stomach and multiple variable size polyps in the antrum (...

Urease gene expression in Streptococcus salivarius 57.I, a strain of one of the major alkali producers in the mouth, is induced by acidic pH and excess amounts of carbohydrate. Expression is controlled primarily at the transcriptional level from a promoter, pureI. Recent sequencing analysis revealed a CodY box located 2 bases 5' to the -35 element of pureI. Using continuous chemostat culture, t...

The purpose of this investigation was to evaluate the physicochemical properties of gray and white structural and nonstructural Portland cement, gray and white ProRoot MTA and MTA BIO. The water/powder ratio, setting time, solubility and pH (hydrogen-ion potential) changes of the materials were evaluated. Tests followed specification #57 from the American National Standard Institute/American De...

The aim of the study was to determine effect selected reaction parameters—temperature (37–57 °C), pH (5.8–7.9), substrates ratio (sucrose/sorbitol 0.5/1.5 1.5:0.5 (m/m)), and presence NaCl—on course fructosyl-sorbitol synthesis with an enzyme preparation (11 760 U/100 g sucrose) containing fructosyltransferase β-d-fructofuranosidase from Aspergillus niger. A mixture at least three fructosyl sor...

Latest data on charmless strange vector-pseudoscalar B decays now including B → ρK confirm a simple penguin model in which the gluon G in an initial s̄uG state fragments equally into uū, dd̄ and ss̄ and all form factors are equal. A search for possible additional contributions shows only a few signals not obscured by experimental errors whose implications are discussed. The experimental value of 0...

Hydrolyses of beta-cyclodextrin cinnamate (betaCDC) and alpha-cyclodextrin cinnamate were catalyzed by amines such as 1,4-diazabicyclo(2.2.2)octane, triethylamine, quinuclidine, piperidine, diisobutylamine, and n-butylamine. The rate constant of hydrolyses of the betaCDC-amine complexes follows the order: 1,4-diazabicyclo(2.2.2)octane > n-butylamine > quinuclidine > piperidine > triethylamine >...

We consider structure formation and cosmic microwave background (CMB) aniso-tropies in a closed universe, both with and without a cosmological constant. The CMB angular power spectrum and the matter transfer function are presented, along with a discussion of their relative normalization. This represents the rst full numerical evolution of density perturbations and anisotropies in a spherical ge...

Introduction: Increasing microbial resistance to antibiotic medications are a common phenomenon in developing countries and development country. In this study, administration of correct, incorrect and inappropriate antibiotic in children under 7 years of age with Gastroenteritis in the pediatric ward of Imam Reza (AS) in the years 2012-2013 was performed Bojnurd-Iran. Materials and Methods: ...
