nano technology has a large number of applications in different fields of science and technology. nano particle are the tiny particles which are being used in upcoming technology due to their small size and high capability. the properties of nanoparticles depend largely on their synthesis procedures. there are different methods for the synthesis of nano particles using different conditions. in ...

as the incidence of obesity increases, less invasive weight loss methods rather than bariatric surgery will be needed. this article reviews the advances in endoscopy, results, benefits and side effects of these techniques for treating obesity. the endoscopic options for weight loss could be broadly grouped under the following categories: restriction procedures, malabsorption procedures, and neu...

A thorough understanding of normal ocular anatomy is critical to define pathologic anatomic conditions, to delineate surgical goals, and to develop and utilize surgical tools to optimize patient outcomes. The anatomy of the eye and orbit can be broadly categorized as extraocular structures (including the eyelids, lacrimal gland, canalicular system, conjunctiva, and extraocular muscles) and intr...

Background Sperm preparation before assisted reproductive techniques is very important for obtaining successful fertilization and pregnancy. During ICSI technique, sperms are selected based on viability and morphology. But this selection did not guarantee integrity of sperm DNA. Therefore, novel sperm selection procedures are introduced for selection of sperm with low DNA damage. One of these p...

Some consider assessment in terms of a systematic way of gathering and evaluating information within educational system and particularly higher education. Since, the term ‘’assessment’’ refers and relates to administrative processes, this paper has shed light some consideration on how it can benefit the members of department and program. Program assessment ultimately emphasizes on direction for...

Discrete-event simulation optimization is a problem of significant interest to practitioners interested in extracting useful information about an actual (or yet to be designed) system that can be modeled using discrete-event simulation. This paper presents a brief survey of the literature on discrete-event simulation optimization over the past decade (1988 to the present). Swisher et al. (2000)...

OBJECTIVE To provide an overview on the current status of the long-term outcomes of instrumental treatment options for patients with lower urinary tract symptoms that are suggestive of bladder outlet obstruction. METHODS Based on MEDLINE database searches, we performed a systematic review of the literature with a focus on peer-reviewed articles about surgical benign prostatic hyperplasia (BPH...

interventional techniques aim to find safer and better ways to treat vascular diseases even in many instances, the interventional radiology solutions has been considered the only treatment option for the patients. interventional radiologists are specialists who perform minimally invasive procedures instead of surgery or other treatments. these procedures apply various imaging and catheterizatio...

Introduction: The healing process after surgery is a challenging issue for surgeons. Various materials and techniques have been developed to facilitate this process and reduce its period. Fibrin adhesives are often used in cardiothoracic and vascular surgery to seal diffuse microvascular bleeding and in general and plastic surgery to seal wound borders. This Case report and literature review ...
