We recovered molecular phylogenetic relationships amongst species of the genus Ablepharus in Iran and Iraq. Partial sequences three mitochondrial genes (cytochrome C oxidase subunit I – COI, 12S rRNA 16S rRNA) were analysed. In addition, taxonomic evaluation Cyprus, India, Greece, Turkey Syria performed using partial gene. Phylogenetic trees estimated genetic distances showed that populations I...
abstract. rangeland vegetation dynamics encompass all processes of changes in vegetation composition and structure over time. investigating the rangeland ecosystem dynamics makes it possible to determine the effects of climatic and management conditions on qualitative and quantitative changes of the vegetation in a specific period of time. accordingly, data collection and measurements for evalu...
Kurds of Khorasan regions live in its northern regions and are called kurmanj. During the rule of the Safavid dynasty, Kurds of Turkey, Syria and Caucasus in west Azerbaijan were moved to Khorasan to evade invasions of the Ottomans and were settled there. This movement of Kurds from Western Iran to northern Khorasan and their adjacency with Balooch and Turkmen people influenced their carpet wea...
an investigation was carried out to study the developmental time, reproduction and life table of three populations of the onion thrips, thrips tabaci lindeman, on onion (khorasan and golestan populations) and also on tobacco (mazandaran population) in the laboratory at 25â°c, 50% rh and 16: 8 h l: d. the total life cycle from egg to adult of khorasan, golestan and mazandaran populations were ga...
BACKGROUND Echinococcus multilocularis is the source of alveolar echinococcosis, a potentially fatal zoonotic disease. This investigation assessed the presence of E. multilocularis infection in definitive hosts in the Chenaran region of Razavi Khorasan Province, northeastern Iran. METHODOLOGY/PRINCIPAL FINDINGS Fecal samples from 77 domestic and stray dogs and 14 wild carnivores were examined...
Introduction Given the fact that children are more sensitive to radiation, compared to adults, special attention needs to be paid to radiation protection in pediatric radiology. Diagnostic reference level (DRL) has been defined to be employed as a practical tool for examining the overall performance of a radiological center in terms of patient dose among a series of similar equipments in an are...
BACKGROUND Since establishing a safety culture in an organization is considered as the first step in patient safety improvement, there is always a need for updated field evaluation to better plan future decisions. METHODS We performed a cross-sectional, analytic-descriptive study in 25 hospitals related to Mashhad University of Medical Sciences (MUMS) during a 3-month period from April to Jun...
BACKGROUND/AIM Several types of the hepatitis C virus (HCV), with variations in different parts of the genome, have been isolated from different regions of the world. Based on heterogenic sequences in the isolated genome, HCV is classified into different genotypes and subtypes. Data on distribution of HCV genotypes in a certain region could be important to patient management. Therefore, this st...
