nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
background: helicobacter pylori (h. pylori) cytotoxin and its heterogeneity amongst strains has been closely linked to the varying infection-associated clinical outcomes. in order to determine the decisive role of the vacuolating cytotoxin (vaca) gene mosaicism in its corresponding gene expression and phenotype, we aimed to characterize vaca alleles of different h. pylori strains in addition to...
mycoplasma synoviae expressed variable lipoprotein haemagglutinin (vlha) is believed to play a major role in pathogenesis of the disease by mediating adherence and immune evasion. the aim of this study was sequencing iranian m. synoviae isolates for the detection of nucleotide variation in the m. synoviae vlha gene. using oligonucleotide primers complementary to the single-copy conserved 5´ end...
Introduction & Objective: TEM-1 beta lactamase gene is one of the important plasmidic genes in Enterobacteriaceae which is the cause of over 90% of Escherichia coli isolates resistance to beta lactam antibiotics. In this study, the frequency of TEM-1 gene in nosocomial strains of Escherichia coli, Klebsiella pneumoniae and Enterobacter was investigated using PCR. Materials & Methods: In th...
background: caddisflies have significant roles in freshwater ecosystems. morphological identification is the major impediment in accurate species identification of hydropsychids. mitochondrial and nuclear markers are suitable for molecular systematics of these group of arthropods. methods: trichopteran specimens of lavasan district in northeastern tehran, iran were collected in 2012, and descr...
A bacteria strain Bacillus thuringiensis RUN1identifiedby 16s RNA gene phylogenetic analysiswas used to decolorize malachite green, a triphenylmethane dye in simulated wastewater. The ability of the organism produce extracellular laccase and degrade were also investigated. Results showed that decolorized (84.67 ± 1.19 %) green at 40 mgl-1 within 6 h; decolorization was associated production by ...
the current study aimed to detect the presence of helicobacter pylori in some water systems in egypt as well as in blood samples of patients suffering from stomach ulcers.fifty-one water samples collected from some egyptian governorates; giza, alexandria, monofia, beheira, minya, sohag, was subjected to physical and chemical analysis. urease gene urec, a highly specific sequence in h. pylori dn...
We have isolated a Na+/H+ antiporter gene from Aeluropus littoralis under NaCl salt stress. The isolated cDNA is 3981 bp long and contains a 3438 bp open reading frame. The amino acid sequences of PtNHA1 show high identities to SOS1 plant transporters. PtNHA1 is predicted to contain 12 hypothetical transmembrane domains in the N-terminal part and a long hydrophilic cytoplasmic tail in the C-ter...
Objective(s) Staphylococcus aureus is both a successful human commensal and a major pathogen. In this study we investigated the genetic diversity of 26 S. aureus isolates recovered from human skin and urinary tract infections. Materials and Methods Typing procedure for the studied S. aureus isolates was performed based on PCR amplification of the aroA gene, which encodes the enzyme 5-enolpyr...
