coastal region of chah bahar port, sea of oman, was screened for the presence of bioluminescence bacteria for the first time. water samples were taken from surface and subsurface layers and immediately spread on nutrient seawater complete (swc) agar. luminous colonies were observed after an overnight incubation at 25°c. among twenty luminous isolates, four of them were selected for preliminary ...

results approximately 20% of the patients expressed alternatively spliced transcripts of gla mrna involving exon 3. we additionally report that such non-canonical transcripts are physiologically expressed at trace levels in healthy individuals, and that their expression in leukocytes markedly increased in blood samples kept at room-temperature for 48 hours before rna extraction. background defi...

background :    klebsiella pneumoniae is among the most common and significant agents of community and hospital-acquired infections. plasmid mediated quinolone resistance (pmqr) was increasingly identified in enterobacteriaceae family worldwide. plasmid-mediated quinolone resistance (pmqr) was first reported in 1998 from a klebsiella pneumoniae isolate in the usa. till date, five qnr proteins h...

background: an explosion of research has been done in discovering how human health is affected by environmental factors. i will discuss the impacts of environmental cancer causing factors and how they continue to cause multiple disruptions in cellular networking. some risk factors may not cause cancer. other factors initiate consecutive genetic mutations that would eventually alter the normal p...

Objective: The burden of obesity is currently enormous, necessitating a novel strategy to complement the existing ones. Accordingly, genetic predisposition is suspected in many cases of the disease, which can potentially be used as therapeutic targets. However, there are differing viewpoints on the suspect genes, prompting the current review to articulate the genes and their mechanisms. Eight (...

Lung injury is one of the major concerns for chest cancer patients that undergo radiotherapy as well as persons exposed to an accidental radiological event. Reduction/oxidation (redox) system plays a key role in lung injury via chronic upregulation of pro-oxidant enzymes. NOX2 and NOX4 are two important reactive oxygen species generating enzymes that are involved in radiation toxicity in some o...

Pertussis is still endemic and the recently resurgence of the disease caused by Bordetella pertussis has been shown in many countries. The polymorphism of the virulence genes of B. pertussis and lack of any information about the allelic variation between the Iranian isolates promotes us to analysis of the genes encoded virulence factors including ptxS1, prn, fim3 and cya to understand the diffe...
