background: retinoblastoma is the most common intraocular tumor in childhood and mutation in the rb1 gene will trigger the tumorigenesis. so far, a wide range of the mutations along the length of rb1 gene have been reported. however, some could not be detected by common detection methods. in such condition, linkage analysis using microsatellite markers is suggested to trace unknown rb1 mutation...

molecular characterization of 19 jatropha accessions that included 15 accessions of j.curcas and 4 different species was carried out using 3 different markers systems. highest polymorphism (96.67%) was recorded by rapd followed by damd (91.02%) and issr (90%). polymorphism information content (pic) was higher for damd (0.873) and almost equal for rapd (0.863) and issr (0.862) markers, whereas r...

the domesticated silkworm, bombyx mori, is of high commercial importance as a silk producer and is also widely used for implementation of basic and applied research. it is important to understand its genome organization using molecular markers for genetic studies and for breeding purposes. in this study, a genetic linkage map using 204 amplified fragment length polymorphism (aflp) markers was d...

conclusions according to the results obtained in our study, advanced age, higher bmi, ast, alt, and hbv-dna levels, and low albumin and platelet levels are correlated with advanced fibrosis in patients with chb. objectives this study evaluated the correlation between hepatic fibrosis and routine laboratory values in patients with chronic hepatitis b. patients and methods the files of 456 patien...

chronic obstructive pulmonary disease (copd) is a condition associated with inflammation in lungs and airways. the impacts of inflammatory process is not limited to respiratory system but extend to extrapulmonary organs with resultant complications involving endocrine, metabolic and cardiovascular systems. the extent and severity of inflammation may be partly estimated by serum measurement of s...

genetic diversity of five improved varieties (kaysari, kadi, ranger, mesmir, sea-river) and seven iranian landraces (gharayonje, amozeynadin, rahnani, tazekand, shazand, hamedani, yazdi) of alfalfa were assessed using esterase (est), peroxidase (pox), glutamate oxaloacetate transaminase (got) and malate dehydrogerase (mdh). got and mdh were monomorphic, whereas est and pox showed polymorphic ba...

hybrids were produced by crossing female caspian kutum rutilus frisii kutum with male grass carp ctenopharyngodon idella. the genome of eight larvae and parents were studied using microsatellite markers for genetic evaluation and verification. after dna extraction from parent fish and progeny, hybrid heritability of two loci was assessed using two pairs of microsatellite primers. hybridizie...

having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. in present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and rapd markers. significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...

background: aflatoxins are found in the most types of foods such as corn, peanuts, pistachio, rice, milk, and etc. these toxins may cause several adverse health effects, notably cancer. the main aim of this study was to evaluate excretion level of aflatoxin m1 (afm1), as a biomarker of aflatoxin b1 exposure, in urine samples of iranian population. also, relationship between diet and urinary exc...
