Dog Rose is one of the most important species in Rosaceae family used as a medicinal plant and a rootstock for ornamental roses. This species is native to Iran, therefore, identification of indigenous genotypes of this species is important for genetic preservation or breeding purposes. Genetic diversity estimation of plant materials is one of the important pre-breeding activities in breeding cr...
BACKGROUND Plague is a life-threatening disease caused by the bacterium, Yersinia pestis. Since the 1990s, Africa has accounted for the majority of reported human cases. In Uganda, plague cases occur in the West Nile region, near the border with Democratic Republic of Congo. Despite the ongoing risk of contracting plague in this region, little is known about Y. pestis genotypes causing human di...
Although Plasmodium vivax is a leading cause of malaria around the world, only a handful of vivax antigens are being studied for vaccine development. Here, we investigated genetic signatures of selection and geospatial genetic diversity of two leading vivax vaccine antigens--Plasmodium vivax merozoite surface protein 1 (pvmsp-1) and Plasmodium vivax circumsporozoite protein (pvcsp). Using scala...
BACKGROUND Paediatric trauma system development in Alaska is complicated by a vast geographic coverage area, wide regional variations in environment and culture, and a lack of available published data. OBJECTIVE To provide a detailed description of paediatric trauma mechanisms, high-risk injury patterns and outcomes in Alaska. DESIGN This retrospective study included all children aged 17 ye...
Background Diabetic retinopathy has a significant impact in every healthcare system. Despite that fact, there are few accurate estimates in the prevalence of DR in Brazil's different geographic regions, particularly proliferative DR and diabetic macular edema. This study aims to determine the prevalence of diabetic retinopathy in Brazil's five continental regions and its determinant factors. ...
during this survey 29 sites have been recognized totally. settlement patterns determined base of environmental characteristics such as altitude, ground slope, source of water, petrology and geology, vegetations, land use and specifications of sites including width, chronology, regional distribution and density and all of them have been divided by using geographic information systems (gis) and c...
the us, not only failed to predict the occurrence of the middle east revolutions but also failed to understand the depth and the probability of its spread to other countries. while washington was engaged in tactical initiatives in confronting the islamic awakening, the islamic republic of iran took the creativity of a strategic game in hand. this was a three-step profile raised by the supreme l...
Background: Geographic tongue is an inflammatory disorder of unknown etiology that affects the epithelium of the tongue. It has been associated with several cutaneous diseases. Objective: To determine the prevalence of geographic tongue and its association with other cutaneous diseases in patients referred to the dermatology clinic of Razi hospital. Patients and methods: A cross-sectional study...
Climate change creates new challenges for preventing and protecting human health against different diseases that could appear propagate. The Aedes albopictus mosquito species is an important vector like dengue fever or zika. Although this not “indigenous” in Europe, its presence noticed many countries on the continent. Ae. establishment conditioned by species’ characteristics environmental fact...
OBJECTIVE Optimal care of adults with severe acute respiratory failure requires specific resources and expertise. We sought to measure geographic access to these centers in the United States. DESIGN Cross-sectional analysis of geographic access to high capability severe acute respiratory failure centers in the United States. We defined high capability centers using two criteria: (1) provision...
