background: downy mildew caused by plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. so far several dominant resistance genes designated as pl have been identified and their molecular markers linked to these genes are available. however, no information on the resistance genes is available in iranian lines. objective: in this study, the presence of three map-ba...

BACKGROUND The use of biological-based markers of exposure, intermediate effect, outcome, and susceptibility has become standard practice in cancer epidemiology, which has contributed to identification of several carcinogenic agents. Nevertheless, with the exception of biological agents, this contribution, in terms of providing sufficiently strong evidence as required by the International Agenc...

R is a free licensed programming language which presents big interest as tool for bioinformatics data analysis. It essential in research activities related to the analysis of molecular-biological and identification molecular markers. In this article we describe two simple techniquesof using FASTA type sequences genomic genetic order apply functions described below it necessary have installed la...

in an attempt to reconstruct the paleoenvironments of deposition for the middle jurassic baghamshah formation, samples collected from six outcrop sections along the shotori swell were subjected to detailed geochemical analyses. bulk geochemical and biological marker data indicate a logical trend of the variation of organic input, salinity, and oxicity within baghamshah paleoenvironments across ...

results: the only significant difference was the older age of the malignant group vs. benign group (p = 0.001) regarding demographic findings. as concerns the clinical symptoms, presence of abdominal discomfort in pre-diagnosis period was the only significant parameter in malignant group (p = 0.001). additionally, data analysis of patients as a total group showed that specificity (96.4%), posit...

background blood born viral infections such as hepatitis b virus (hbv) are major concerns in chronic hemodialysis (chd) patients and hemodialysis units. undetected hbs ag in the presence of viral dna, occult hbv infection (obi), is a concern in the care of chd patients and hemodialysis unit as a mode of transmission. objectives in this case-control study we compare the frequency of obi in the c...

conclusions according to high prevalence of malnutrition in our patients with esrd undergoing hemodialysis, periodic assessment of nutritional status is necessary in them. meanwhile we found sga as the best tool to assess nutritional status in patients with esrd undergoing hemodialysis, because it can recognize various degrees of malnutrition that may remain undetected by a single laboratory as...
