conclusions the results of this study demonstrated that the p450 cyp141 gene was successfully cloned into a pet26b plasmid vector as an expression vector. in this paper, for the first time in iran, this gene was cloned for more purposes, including the expression and purification of the recombinant cytochrome p450 cyp141 protein. results the cloning of p450 cyp141 gene was confirmed by the enzym...

BACKGROUND Tuberculosis has been announced as a global emergency by World Health Organization and the second infectious agent of mortality worldwide. The general policy in the development of new vaccines is to develop some vaccines with higher efficiency not only for infants but also for adults compared with the Bacillus Calmette-Guerin vaccine. Recently, cytochrome P450 cyp141 has been introdu...

conclusions in this experimental study, for the first time in iran the expression and purification of this recombinant protein was done successfully. this recombinant protein could be used as a vaccine candidate and diagnostic purpose in subsequent investigations. results the highest expression of the cytochrome p450 cyp141 protein was obtained by the addition of 1 mm of isopropyl β-d-1-thiogal...

background and objectives: for further confirmation of the previous in-house real-time pcr and cyp 141 target as a rapid and cheap diagnostic technique and a new target for direct detection of mycobacterium tuberculosis , we evaluated and compared the results of smear, culture and real-time pcr in sputa that were collected from 2 health centers. moreover we tried to evaluate the diagnostic accu...

BACKGROUND Tuberculosis (TB) is regarded as a health problem worldwide, particularly in developing countries. Mycobacterium tuberculosis (M. tuberculosis) is the cause of this disease. Approximately two billion people worldwide are infected by M. tuberculosis and annually about two million individuals die in consequence. Forty million people are estimated to die because of M. tuberculosis over ...

alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. the ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. a. borkumensis have two genetic systems for alkane biodegradation. the first system is alkane hydroxylase (alk-b1and alk-b2) and the second system is  cytochrome p450....

a “cocktail”of several probe drugs is often used to evaluate metabolic activity of multiple cytochrome p450 enzymes in one session. some interactions among probe drugs can appear and may impact the rate of biotransformation of other ones. our presented work was to aim on the influence of bupropion on rat cytochrome p450-mediated metabolism of tolbutamide. the biotransformation rates of tolbutam...
