The purpose of this study is to clarify the natural history of the valvular pulmonary stenosis (PS) from the standpoint of the indication for percutaneous transvenous pulmonary valvuloplasty (PTPV). We retrospectively analyzed age-dependent changes of the peak velocity in the pulmonary artery (peak V) using Doppler echocardiography (Doppler), and some other echocardiographic and clinical findin...

PURPOSE The aim of this study was to measure the elasticity of normal placentas using the Virtual Touch quantification (VTQ) technique. METHODS This study was approved by the Institutional Ethics Committee. Fifty randomly selected, healthy pregnant women in their second trimester and 50 randomly selected, healthy pregnant women in their third trimester with a single fetus were included, and t...

OBJECTIVE The purpose of this study is to investigate whether acoustic radiation force impulse (ARFI) elastography with ARFI quantification and ARFI 2-dimensional (2D) imaging is useful for differentiating hepatic hemangiomas from malignant hepatic tumors. MATERIALS AND METHODS One-hundred-and-one tumors in 74 patients were included in this study: 28 hemangiomas, 26 hepatocellular carcinomas ...

Bioassay cages are commonly used to assess efficacy of insecticides against adult mosquitoes in the field. To correlate adult mortality readings to insecticidal efficacy and/or spray application parameters properly, it is important to know how the cage used in the bioassay interacts with the spray cloud containing the applied insecticide. This study compared the size of droplets, wind speed, an...

Abstract In this work, the impact of good manufacturing practices (GMP) on specific energy consumption (SEC) plastic injection molding process, in 9 representative companies Colombia, was studied. The GMP applied to process and degree which they are adopted by were defined. Afterwards, SEC 17 processes those evaluated. Finally, applying their effect application analyzed ranges from 35 72%. A si...

Maxwell equation ∂F = 0 for F ∈ sec ∧2 M ⊂ sec Cl(M), where Cl(M) is the Clifford bundle of differential forms, have subluminal and superluminal solutions characterized by F 2 6= 0. We can write F = ψγ21ψ̃ where ψ ∈ sec Cl(M). We can show that ψ satisfies a non linear DiracHestenes Equation (NLDHE). Under reasonable assumptions we can reduce the NLDHE to the linear Dirac-Hestenes Equation (DHE)....

BACKGROUND Cardiac complications are among the most serious problems of thalassemia intermedia patients. The current study was initiated to address the latter issue through the study of the echocardiographic findings and correlate it with clinical characteristics of thalassemia intermedia patients in Duhok, Kurdistan region, Iraq. METHODS An echocardiographic assessment of 61 beta-thalassemia...

IZAKI A., SHIMO-OKU M. Deparfment of Ophthalmology, Hyogo College of Medicine (Japan) Puroose : Blink reflexes evoked with comeal sensation or flash light stimulation are widely performed to examine optic, trigeminal and facial nerve. Both the electro-oculographic findings of lid movements and scleral search coil findings of eye movements during those blinks were investigated previously, we stu...

Input impedance of the pulmonary arterial system was determined in 10 subjects undergoing elective cardiac catheterization. No cardiovascular or pulmonary disease was found in these patients. In five of the subjects, systemic arterial impedance was also obtained, so that both systems could be compared. Pulmonary and systemic peripheral resistances were 79 +/- 9 dynes sec/cm5 (mean +/- SEM) and ...
