Minimally Invasive Surgery (MIS) has established a revolution in surgical communities, with its many advantages over open surgery. The need of more simplicity and high maneuverability makes the tendon sheath a very suitable mechanism in flexible endoscopic systems. Due to the restriction on size constraints and sterilization problems, traditional sensors cannot be mounted on the tool tips of a ...

Background: Erythropoietin (EPO) is known as a regulating hormone for the production of red blood cells, called erythropoiesis. Some studies have shown that EPO exerts some non-hematopoietic protective effects on ischemia-reperfusion injuries in myocytes. Using echocardiography, we evaluated the effect of EPO infusion on reducing ischemia-reperfusion injuries and improvement of the cardiac func...

 Abstract Background: End-to-side esophagojejunostomy has almost always been associated with some degree of dysphagia. To overcome this complication we decided to perform an end-to-end anastomosis and compare it with end-to-side Roux-en-Y esophagojejunostomy. Methods: In this prospective study, between 1998 and 2005, 71 patients with a diagnosis of gastric adenocarcinoma underwent total gastrec...

Introduction: Biological Width is needed to maintain the health of gingiva around teeth that need restoration. Crown Lengthening (CL) surgery can be used to prevent  invading the BW by sub-gingival restoration. The aim of this study was to evaluate gingival indices before and after CL surgery. Materials and Methods: In this analytical-longitudinal study, 23 teeth of 18  patients referred to ...

introduction: epinephrine-containing lidocaine is the most used anestheic drug in dentistry. the aim of this study was to investigate the hemodynamic changes following local infiltration of 2%lidocaine with 1:80,000 epinephrine in subjects undergoing orthognatic surgery under general anesthesia. methods: twenty five patients without any systemic disease participated. after general anesthesia, t...

Recently, Google Deepmind showcased how Deep learning can be used in conjunction with existing Reinforcement Learning (RL) techniques to play Atari games[11], beat a world-class player [14] in the game of Go and solve complicated riddles [3]. Deep learning has been shown to be successful in extracting useful, nonlinear features from high-dimensional media such as images, text, video and audio [...
