we studied cu concentration on part of aras riparian vegetation. cu was selected as an index metal due to polluting the aras river through agarak copper mines drainage. results of cu concentration in indicator plant have been examined using spss16. considering the situation of the copper mines as well as the habitat of the indicator plant, two stations before and after the exit of the industria...

OBJECTIVE Increased mean platelet volume (MPV) has been reported in various atherosclerotic diseases. The aim of our study was to investigate the relationship between the atherosclerotic renal artery stenosis (ARAS) and various hematological parameters including MPV. METHODS This study was performed with a retrospective review of the angiographic images of patients who underwent renal angiogr...

Compared to conventional general-purpose processors, accelerator-rich architectures (ARAs) can provide ordersof-magnitude performance and energy gains and are emerging as one of the most promising solutions in the age of dark silicon. However, many design issues related to the complex interaction between general-purpose cores, accelerators, customized on-chip interconnects, and memory systems r...

BACKGROUND Hospitalists involved in perioperative care either stop or continue until the day of surgery renin-angiotensin-aldosterone system antagonists (either angiotensin-converting enzyme inhibitors [ACEI] or angiotensin II receptor subtype 1 antagonists [ARA]) in patients who use these agents chronically. This practice variation reflects uncertainty regarding the risks and benefits of eithe...

The combination of habitat loss, climate change, direct persecution, introduced species and other components of the global environmental crisis has resulted in a rapid loss of biodiversity, including species, population and genetic diversity. Birds, which inhabit a wide spectrum of different habitat types, are particularly sensitive to and indicative of environmental changes. The Caucasus endem...

We report on a patient who survived cardiac arrest and showed recovery of consciousness and an injured ARAS at the early stage of hypoxic-ischemic brain injury (HI- BI) for 3 weeks, which was demonstrated by diffusion tensor tractography (DTT).A 52-year-old male patient who had suffered cardiac arrest caused by acute coronary syndrome was resuscitated immediately by a layman and paramedics for ...

The genetic variation and population structure of narrow-clawed crayfish (Astacus leptodactylus) was examined by means of polymerase chain reaction (PC R) restriction fragment length polymorphism (RF LP) analysis of the cytochrome oxidase subunit I (COI) of mitochondrial DNA. A total of 194 adult specimens were collected from seven sample sites including, two in the south Caspian Sea and one ea...

Renal artery stenosis (RAS) is frequently associated with severe comorbidities such as reduced renal perfusion, hypertension, and end-stage renal failure. In approximately 90% of patients, renal artery atherosclerosis is the main cause for RAS, and it is associated with an increased risk for fatal and non-fatal cardiovascular and renal complications. Endovascular management of atherosclerotic R...

We employ mixed reality as a collaborative tool for intra-operative planning of extended liver resections. The most important advantage of real time visualization of intrahepatic vascular structures using see-through glasses is the improved accuracy of the preparation of liver parenchyma. The impact of using augmented reality as an intra-operative navigation system should result in sparing sane...

OBJECTIVES Percutaneous transluminal renal angioplasty with stent implantation (PTRAS) has become the treatment of choice for atherosclerotic renal artery stenosis (ARAS). This study evaluates the long-term effects of PTRAS on hypertension and renal function in elderly patients with ARAS. METHODS We conducted a retrospective cohort study of all patients who underwent PTRAS in the geriatric di...
