background: stroke is the most common neurologic disease and an important cause of morbidity and mortality. headache is an initial presenting feature of ischemic stroke and sometimes preceedes the development of stroke and thus, provides an opportunity for offering preventive measures. the aim of the present study was to determine the association of new onset headache with stroke. methods: a to...

background since the discovery of helicobacter pylori, several clinical reports have demonstrated that h. pylori infection has emerged as a new cause of refractory iron stores in children. we carried out a systematic literature review to primarily evaluate the existing evidence on the association between childhood h. pylori infection and iron deficiency anemia (ida) and secondly, to investigate...

Three Hypomyces and one Cladobotryum species are studied and reported as new records and also new anamorph/teleomorph connections of fungicolous fungi for Iran. Anamorphs of two species H. aurantius and H. rosellus (Cladobotryum varium and C. dendroides, respectively) have already been reported from Iran. The anamorph/teleomorph association of H. polyporinus/C. clavisporum was also found and wa...

potato virus y (pvy) is one of the most important pathogenic agents that reduce the yield and quality of tobacco (nicotiana tabacum l.). dna-based molecular markers are valuable tools for identifying germplasm in gene banks, assessing kinship ties, and doing marker-assisted selection (mas) for resistance to pests, diseases, and some crop traits of interest. this work presents the results of ass...

morphological and rapd markers were used to investigate the genetic diversity among 21 accessions of pomegranate originating from south eastern tunisia. thirteen morphological traits were studied and results showed significant differences for all morphological characters (p< 0.001). clustering based on fruit traits, using ward’s method, divided the accessions into three main groups. in rapd ana...

association analysis is a useful method for evaluation of significant association between molecular marker and phenotype of trait. this study was performed to evaluate association between traits related with powdery mildew resistance and molecular markers. this investigation was performed using 77 barley genotypes and aflp markers. in phenotypic evaluation, reaction of seedlings to powdery mild...
