background hepatitis b virus (hbv) infection is a serious public health problem in china and worldwide. mother-to-child transmission is one of hbv’s main transmission routes in highly endemic regions. genome-wide association studies (gwas) identify single nucleotide polymorphisms (snps) at hla loci as associated with hbv infection. however, the mechanisms of hbv perinatal transmission and break...

DNA markers help detect the intraspecific genetic diversity of yeast strains. Eight ISSR (Inter Simple Sequence Repeats) primers were used to assess Saccharomyces cerevisiae (n = 96) from different populations 3), evaluate technological characteristics, and investigate trait-loci associations. The amplified 154 reproducible scorable bands, which 79.87% polymorphic. UPGMA (unweighted pair group ...

Mental retardation (MR) is one of the most frequently found major genetic disorders around the world, affecting 1-3% of the people in the general population. The recent advancement in molecular biology and cytogenetic study has made possible the identification of new genes for a variety of genetic disorders including autosomal recessive MR. Recessive genetic disorders are common in Pakistan due...

japanese plum (prunus salicina lindl.) having originated from china, is now one of the important fruit trees in many countries in the world. knowledge of genetic diversity among existing germplasms provides the possibility of parental selection in breeding improvement programs. for assessment of genetic diversity and relationship among genotypes in iran (ramsar, velyan karaj and mashhad) and fo...

cattle have an important role in primary human civilization, so molecular studies for more accurate recognition of their origin are effective to identify unknown historical aspects. cattle can be divided in to 2 main groups including bos tuarus and bos indicus. both types of cattle can be found in iran; therefore study of their origin has particular importance. the aim of this study was to inve...

the main objective of this study was to assess genetic comparison of two migratory forms of caspian trout salmo trutta caspius namely fall-run and spring-run. owing to the lack of information on its genetic differences, 5 microsatellite loci were used for 58 sample analyses. genomic dna was extracted from caudal fin using roche dna extraction kit and each pcr reaction was performed in a 25 ?l r...
