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...
Background and purpose: The incidence of tuberculosis (TB) in Iran is about 13 in 100000 people and this rate in Golestan and Sistan & Balouchestan Provinces is the highest. Due to the proximity of Golestan to Mazandaran, this epidemiological survey has been done to identify the high risk locations by using of disease mapping of tuberculosis incidence rate. Materials and methods: This obse...
genetic resources constitute the building blocks of crop improvement programs. these provide the basic raw material as well as reservoir of genes for breeding high-quality cultivars. characterization of germplasm is the prerequisite for subsequent utilization of the resources. in this study, suckers of twenty six damask rose genotypes (rosa damascena mill.) were collected from some of the most ...
Maedi-Visna (MV) virus and caprine arthritis encephalitis (CAE) virus known as small ruminant lentiviruses (SRLVs) cause chronic diseases in susceptible animals. The main reservoirs of these viral agents are sheep and goat. In sheep, MV virus causes a disease as the same name of the virus. This is the first seroprevalence survey of SRLVs in sheep population of Khorasan-e-Razavi province in Iran...
