euphorbia wallichii a perennial herb growing mainly in himalayas has been widely used in folk medicines for its medicinal properties. in the present study, the crude methanolic root extract (cme) and its fractions; n-hexane fraction (nhf), n-butanol fraction (nbf), chloroform fraction (chf), ethyl acetate fraction (eaf) and aqueous fraction (aqf) of this plant specie were investigated for antio...

a restriction-site analysis of chloroplast dna (cpdna) was carried out to evaluate the levelof diversity in vicia faba l. germplasm selected from different geographical regions using 11 restrictionendonucleases. we analyzed 214 restriction sites in 18 accessions of vicia faba. all of the accessionshad identical cpdnas, pointing out the ancestral character of all the accessions are of only one g...

heredity hearing loss (hl) is the most prevalent sensory disorder and most cases are non-syndromic. eighty percent of non-syndromic sensorineural deaf patients show an autosomal recessive pattern of inheritance. to date, 47 genes and 98 loci have been reported for this mode of inheritance. previous studies in our center showed the high prevalence of dfnb3 among iranian deaf families. pjvk (dfnb...

To investigate the patterns of DNA ploidy and proliferating activity in breast cancer and relate them to other prognostic factors, paraffin blocks of 53 cases of breast carcinoma were studied. Cancer cells obtained by mechanical tissue disaggregation were examined for DNA content, ploidy and S-phase fraction. DNA assay was done using a CAS interactive image analyzing system. All of the cas...

Although the first ancient DNA molecules were extracted more than three decades ago, nuclear genomes could only be characterized after high-throughput sequencing was invented. Genome-scale data have now been gathered from thousands of archaeological specimens, and number biological tissues amenable to genome is growing steadily. Ancient fragments are typically ultrashort carry extensive amounts...
