background uropathogenic escherichia coli (upec) is a causative agent of most of urinary tract infections (utis), which expresses a multitude of virulence factors. objectives the aim of this study was to investigate virulence associated characteristics characteristics in upec isolates derived from urine specimens, and to investigate the distribution of the pathogenicity islands virulence marker...

dermatophytes are a group of keratinophilic fungi capable of invading keratinized tissues (skin, hair and nails). they cause dermatophytosis (commonly known as tinea or ring worm) in human and animals. in this report, dna similarities and genomic linkage of 40 dermatophytes strains was obtained from different universities, were studied by random amplified polymorphic dna (rapd–pcr) using 11 ran...

sulfur mustard (sm, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes dna alkylation, protein modification and membrane damage. sm can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. epigenetic regulation of gene expression is a growing research topic and is ...

GSTaxClassifier (Genomic Signature based Taxonomic Classifier) is a program for metagenomics analysis of shotgun DNA sequences. The program includes a simple but effective algorithm, a modification of the Bayesian method, to predict the most probable genomic origins of sequences at different taxonomical ranks, on the basis of genome databases;a function to generate genomic profiles of reference...

background: nematodes are among the most common and important parasites of man and animal. dna of a single worm can be used for several purposes, such as identification to the species, subspecies, strain and antihelmenthic resistance. dna extraction from a single small worm using traditional methods such as phenol extraction technique faces serious prob lems. methods: dna from 20 single haemonc...

Transfer RNA (tRNA) is a key molecule to decode the genetic information on mRNA to amino aicds (protein), in a ribosome. For tRNA to fulfill its adopter function, tRNA should be processed into the standard length, and be post-transcriptionally modified. This modification step is essential for the tRNA to maintain the canonical L-shaped structure, which is required for the decoding function of t...
