INTRODUCTION. Arteriovenous fistulas and grafts are two common permanent access methods for hemodialysis. Selection of an appropriate access, appropriate surgical techniques, and treatment of complications are basic principles of long-term maintenance of vascular access. We aimed to assess the survival of arteriovenous fistulas and grafts in our dialysis center. MATERIALS AND METHODS. A total o...

Background: The entry of heavy metals into the food chain is an important environmental challenge for humans. Due to their potential accumulating in body, different aspects hazard posed by should be carefully examined. Objectives: present study was conducted determine concentrations such as Arsenic (As), Cadmium (Cd), Chromium (Cr), Lead (Pb), and Nickel (Ni) tuber crops i.e., potatoes onions R...

background: cardiac manifestations that occur in a majority of patients with organophosphate (op) poisoning may range from innocuous electrocardiographic manifestations, such as sinus tachycardia, to life-threatening complications, including cardiogenic pulmonary edema and myocardial necrosis. in this study, we evaluated the various electrocardiographic manifestations in patients with op poison...

The previously monotypic genus Pseudorhopalia Wilcox & Papavero, 1971 is here revised, with description of a new species, Pseudorhopalia manauara, sp. n. The type-species, P. mirandai (d'Andretta & Carrera, 1951), is only found in northeastern Brazil, in the semiarid Caatinga biome. On the other hand, the new species is found in the humid Brazilian Amazonia, within dense ombrophilous forest and...

New Zealand contains 13 of the 69 species of Crotonia described globally and is the only place where all three genera of the Crotoniinae-Crotonia, Austronothrus and Holonothrus-have been recorded. Due to the pioneering work of Hammer (1966) and Luxton (1982) it also has the highest number of distribution records of Crotonia spp. anywhere. In the present study I build upon previous work to re-ex...

For the first time, sulfur dioxide concentration was monitored between 2005 and 2016 over Iran which is among the countries with a high SO2 emission rate in the world. To that end, SO2 column concentration at Planetary Boundary Layer (PBL) from Ozone Monitoring Instrument (OMI) was analyzed. OMI is a sensor onboard the Aura satellite which can measure daily SO2 concentration on the global scale...
