abstract background: production of advanced glycation end products (ages) is directly linked to the level and duration of hyperglycemia in diabetic patients. oxidative stress plays a major role in the pathogenesis of diabetes mellitus. free radicals are f01med in diabetes by glucose oxidation, nonenzymatic glycation of proteins and subsequent oxidative degradation of glycated proteins. thiobarb...

two types of mineralization including porphyry copper and epithermal gold mineralization have occurred in relation with an intermediate volcano-plutonic complex in masjeddaghi area. different alterations including silica, advanced argillic, intermediate argillic and propylitic have been distinguished in relation with epithermal mineralization, which have a zonal pattern. elemental mass gains an...

background: the incidence of colorectal cancer is rising in several developing countries. in the absence of integrated endoscopy and pathology databases, adenoma detection rate (adr), as a validated quality indicator of screening colonoscopy, is generally difficult to obtain in practice. we aimed to measure the correlation of polyp-related indicators with adr in order to identify the most accur...

background: monte carlo simulations play a vital role in the calculation of the necessary shielding both for neutrons and photons. advanced and simple shielding materials against neutron and gamma rays were compared by simulation using the mcnb4b monte carlo code. the simulations were carried out for the three common neutron sources, namely the 252cf, the 241am/be and the dd neutron generator w...

During recent years, many advanced oxidation techniques have been investigated for water and wastewater treatment to overcome the shortage of clean water. This review summarizes the background and principles of photocatalysis applied as an advanced oxidation technology. In particular, this paper focuses on modification of photocatalysts with various dopants as well as the novel photocatalytic r...

In this paper, the speed tracking for permanent magnet synchronous motor (PMSM) in field oriented control (FOC) method is investigated using linear proportional-integral (PI) controller, sliding mode controller (SMC) and its advanced counterparts. The advanced SMCs considered in this paper are fuzzy SMC (FSMC) and sliding mode controller with time-varying switching gain (SMC+TG) which can effec...

this paper explains offset and develops a strategic approach for the implementation of offset-policy for a buyer country. offset emerges when a country cannot afford to pay cash for non-essential imports, and cannot get cash for many of its products. offset arrangements are most frequently found in the defense-related sector. however, recently, it refers to a range of industrial and commercial ...

long-term mechanical circulatory support is a life-saving technology while briding to heart transplantation. it increases the quality of life and preserves end-organ function for patients with  advanced heart failure. the number of patients with advanced heart failure scheduled for heart transplantation before comorbidities escalate is on the rise. however, the device function is complicated by...

Management of locally advanced colon cancer metastases is challenging and operation carries an increased risk of morbidity and mortality. The knowledge of exact sites of involvement can aid the surgeon to make a decision regarding complete resection or palliative therapy. PET/CT scan is an advantage in this setting because metabolic alterations often precede the anatomic changes; moreover, it c...
