Intermittent malfunction and regurgitation of a mitral prosthetic valve due to entrapment by a residual subvalvular apparatus
(Blackwell Publishing Inc., 2018)
Intermittent malfunction is a rare but potentially serious complication of prosthetic heart valve (PHV) replacement. It may be observed in both mitral and aortic valve prosthesis and may lead to either paroxysmal obstruction ...
Use of a superficial femoral artery autograft as a femoral vein replacement
(Elsevier Inc., 2015)
Posttraumatic arteriovenous fistulas (AVFs) are common complications of vascular penetrating trauma. Here we present a case of a 59-year-old woman who had a history of gunshot injury 42 years ago causing AVF between ...
A novel suture technique for distal aorta-graft anastomosis in aortic aneurysm repair surgery: Diagonal basting stitch
(Elsevier Inc., 2015)
We describe a novel suture technique of distal anastomosis between the graft and the aorta in ascending aortic aneurysm repair surgery. In this technique, the aortic graft is positioned inside the distal aortic lumen with ...
Groin swelling in a four-year-old boy: Primary great saphenous vein aneurysm
(Elsevier Inc., 2015)
Primary venous aneurysm, especially in pediatric population, is a very rare clinical entity. We report a case of primary great saphenous vein aneurysm in a 4-year-old boy. He was initially suspected of suffering from ...
Analysis of current conduction mechanism in CZTSSe/n-Si structure
(Springer New York LLC, 2018)
In this study, Cu2ZnSn(S,Se)4 (CZTSSe) thin films were deposited by the single step thermal evaporation process using the sintered powder of CZTSSe on soda lime glass (SLG) and Si wafer substrates. The structural, optical, ...
Study on the electrical properties of ZnSe/Si heterojunction diode
(Springer New York LLC, 2017)
ZnSe thin film is e-beam evaporated on monocrystalline p-Si to fabricate n-ZnSe/p-Si heterojunction. The electrical properties were investigated by current–voltage (I–V), capacitance–voltage (C–V) and conductance–voltage ...
Electrical properties of Au–Cu/ZnO/p-Si diode fabricated by atomic layer deposition
(Springer New York LLC, 2018)
The electrical properties of the Au–Cu/ZnO/p-Si diode were investigated with the temperature dependent current–voltage measurements in a wide temperature range from 220 to 360 K with 20 K steps and also frequency dependent ...
Analysis of analytical capacity for Fisher-Snedecor F fading channels with different transmission schemes
(Institution of Engineering and Technology, 2019)
This Letter presents capacity analysis of Fisher-Snedecor F fading channels under different transmission strategies. To this end, novel analytical expressions are proposed for optimal rate adaptation with constant transmit ...
Intramolecular Gold-Catalyzed and NaH-Supported Cyclization Reactions of N-Propargyl Indole Derivatives with Pyrazole and Pyrrole Rings: Synthesis of Pyrazolodiazepinoindole, Pyrazolopyrazinoindole, and Pyrrolopyrazinoindole
(American Chemical Society, 2015)
Gold-catalyzed and NaH-supported intramolecular cyclization of N-propargyl indole derivatives with pyrazole and pyrrole units attached to indole is described. An efficient route to the synthesis of pyrazolodiazepinoindole, ...
Design of pyrazolo-pyrrolo-pyrazines and pyrazolo-pyrrolo-diazepines via AuCl3-catalyzed and NaH-supported cyclization of N -propargyl pyrazoles
(American Chemical Society, 2015)
A concise synthetic methodology for new heterocyclic scaffolds, such as pyrazolo-pyrrolo-pyrazine and pyrazolo-pyrrolo-diazepine skeletons, was developed. The key features of this method include (i) synthesis of pyrrole-derived ...
