helicobacter hepaticus was discovered in 1992 as a cause of liver cancer in the a/jcr mouse model. in susceptible mice, infection by h. hepaticus causes chronic gastrointestinal inflammation leading to neoplasia. it can also cause morphological changes in breast-glands leading to neoplasm and adenocarcinoma in mouse models. studies performed on humans have revealed that h. hepaticus may also be...

Previous studies have indicated that in all land plants examined to date, the chloroplast gene trnLUAA isinterrupted by a single group I intron ranging from 250 to over 1400 bp. The parasitic Epifagus virginiana haslost, however, the entire gene. We report that the intron is missing from the chloroplast genome of twoarctic species of the legume genus Hedysarum (H. alpinum, H. ...

growing amount of information on biological sequences has made application of statistical approaches necessary for modeling and estimation of their functions. in this paper, sensitivity and specificity of the first and second markov chains for prediction of genes was evaluated using the complete double stranded  dna virus. there were two approaches for prediction of each markov model parameter,...

genomic signal processing is a relatively new field in bioinformatics, in which signal processing algorithms and methods are used to study functional structures in the dna. an appropriate mapping of the dna sequence into one or more numerical sequences enables the use of many digital signal processing tools in the analysis of different genomic sequences. also, a novel influenza a (h1n1) virus o...

The late sexual maturity in sturgeon and the absence of morphological differences between males and females makes sex discrimination difficult. Identification of sex at an early life stage is of high interest in caviar production because it allows efficient selection of females. In this study, the genome of 10 mature male and 10 mature female specimens of Persian sturgeon (Acipenser persicus...
