Primary hepatocellular carcinoma (PHC), epidemiologically associated with chronic hepatitis B virus (HBV) infection, has historically been felt to be caused by the activation or introduction of an oncogene. However, transforming sequences from human PHC have not been reproducibly isolated. In this paper, evidence is presented that suggests PHC may result instead from the loss of an anti-oncogen...

background: hemophilia b is an x-linked recessive coagulation disorder caused by factor ix deficiency.  analysis of factor ix gene polymorphisms is considered the best approach for prenatal diagnosis and carrier detection of hemophilia b where the identification of gene mutation is not easily possible.   objective: to study the frequency of three factor ix-linked restriction fragment length pol...

conclusions this is the first research in comparing two genetic marker systems in p. variotti. we were prompted to explore polymorphisms utility in p. variotti with a look at using germplasm screening mapping of genome and strain improvement programs. results both systems discriminated 20 isolates of p. variotii successfully but were different in the amount of detectable polymorphism. using clu...

Source/Description: The Human Transition Protein 1 gene (TNP1) probe (1) used was a 700 bp genomic DNA sequence cloned into the Smal site of pUC8 and was supplied by W.Engel. Polymorphisms: TNP1 identifies a two allele polymorphism with TaqI: Al = 9.6 kb; A2 = 8.4 kb. Frequency: Analysis of 20 unrelated individuals yielded frequencies: Al = 0.23; A2 = 0.77. Rsal in a screen of 10-20 unrelated i...

A multi-marker nuclear genotyping approach was performed on larval and adult specimens of Anisakis spp. (N = 689) collected from fish and cetaceans in allopatric and sympatric areas of the two species Anisakis pegreffii and Anisakis simplex (s. s.), in order to: (1) identify specimens belonging to the parental taxa by using nuclear markers (allozymes loci) and sequence analysis of a new diagnos...
