Primary heart tumors are not common. Âlthough myxoma is the most common tumor of the heart, mitral valve myxoma is extremely rare. The patient is a 55 years old woman who had atypical retrosternal pain, retinal artery emboli and visual deficit. Ïn transesophageal echocardiography a (4x3x3) cm mass was detected in posterior leaflet of mitral valve. The posterior leaflet of mitral valve was tot...
Prolapsed Mitral Valve Syndrome is a common, benign disorder with prevalence of %0.3-6 in population. This syndrome also is known as Barlows Syndrome and Flaapy Mitral Valve Syndrome. Prolapsed Mitral Valve is the dropping of one or two mitral valve leaflet(s) into the left atrium during ventricular systole. This malformation leads to incomplete closing of mitral valve and regurgitates the bloo...
A new species, Aulacoseira wyomingensis, is described from a small seep near Casper, Wyoming, USA, using light and scanning electron microscopy, in which it was the dominant diatom taxon. Valves have large areolae that cover valve face. Spines, when present, are short shield-like, precluding chain formation. Unlike most members of genus, A. wyomingensis appears to lack rimoportulae. While we as...
This software article describes the GATE family of open source text analysis tools and processes. GATE is one of the most widely used systems of its type with yearly download rates of tens of thousands and many active users in both academic and industrial contexts. In this paper we report three examples of GATE-based systems operating in the life sciences and in medicine. First, in genome-wide ...
Introduction: With the development of interventional cardiology in the world, in addition to coronary and aortic diseases, the treatment of heart valve diseases through catheters has recently begun. The treatment of aortic stenosis (which was only possible with open surgery and valve replacement) was first performed in the world in 2002 by Alain Cribier in France with catheter insertion of the ...
The current level of industry development for the gas and oil production equipment requires engineering methods calculating hydraulic characteristics manufactured products. Due to complexity designs distribution control units transportation networks, their components increasingly affect performance regulation. In construction units, pipeline fittings are used, in particular, wedge gate valves s...
Abstract A PLC controlled semi-automatic rotary indexing system for assembly of foot valve is modelled and simulated using CATIA Automation Studio. It comprised part feeders (Conveyors vibratory bowl feeder), face plate, fixtures, components (Body, cap, seal carrier, cover) electro-pneumatic (Electro-pneumatic pick & place press) which are CATIA. The kinematic model mechanism successfully v...
quadricuspid aortic valve (qav) is an uncommon congenital anomaly which was an incidental finding during surgery or autopsy in the past. we present the case of a 44-year-old woman with moderately severe aortic regurgitation due to unequal cusp size qav diagnosed via transesophageal echocardiography. due to echocardiographic imaging improvement, the diagnosis of qav is now easier and earlier tha...
In this paper, novel hybrid MOSFET(HMOS) structure has been proposed to reduce the gate leakage current drastically. This novel hybrid MOSFET (HMOS) uses source/drain-to-gate non-overlap region in combination with high-K layer/interfacial oxide as gate stack. The extended S/D in the non-overlap region is induced by fringing gate electric field through the high-k dielectric spacer. The gate leak...
