conclusions detection and surveillance of the significant sites of mutations in hbv is crucial for clinicians to decide on the choice of antiviral treatment and further management of hepatitis b carriers. objectives this study was carried out to detect mutations in p gene of hepatitis b virus isolated from malaysian hbv carriers. materials and methods a total of 58 sera samples were analyzed by...

background and aims: genotyping assay has been accepted as a guidance in the therapeutic management of human immunodeficiency virus 1 (hiv-1). but, it is not commonly used in our country due to its high running cost. the aim of this study is evaluate an in-house genotyping resistance test (grt) for hiv-1. methods: hiv-1 rna of 20 samples were extracted from plasma and rt nested- pcr was perform...

objective(s):the colorectal cancer stem cells (cscs) with the cd133+ phenotype are a rare fraction of cancer cells with the ability of self-renewal, unlimited proliferation and resistance to treatment. quercetin has anticancer effects with the advantage of exhibiting low side effects. therefore, we evaluated the anticancer effects of quercetin and doxorubicin (dox) in ht29 cancer cells and its ...

background and objectives: the selection of alternative treatment options with antibiotic combinations may be used for successful managing of multidrug-resistant acinetobacter baumannii . the aim of this study was to determine the synergistic effects of ampicillin-sulbactam combined with either levofloxacin or tigecycline against mdr a. baumannii. materials and methods: a total 124 of a.baumann...

background and objectives: pseudomonas aeruginosa is one of the most important causative agents of nosocomial infections especially in icu and burn units. p. aeruginosa infections are normally difficult to eradicate due to acquired resistance to many antibiotics. recent appearance of carbapenem resistant p. aeruginosa isolates is considered a major healthcare problem. the present study was cond...

hepatitis b virus (hbv) is a crucial public health problem with approximately 350 million affected people and a death rate of 0.5 to 1.2 million per year worldwide. it proceeds to end-stage liver diseases including cirrhosis with hepatic decompensation and hepatocellular carcinoma (hcc). pakistan lies in the endemic region with 3% hbv carrier rate in the country. the differences in disease outc...

conclusions our findings revealed that the zfn technology could be employed to overcome ampicillin resistance by the targeted disruption of the ampicillin resistance gene, which leads to inactivation of β-lactam synthesis. therefore, zfn technology could be engaged to decrease the antibiotic resistance issue with the construction of a zfn archive against different args. to tackle the resistance...

the production of experimentally induced drug resistance in the laboratory provides valuable opportunities for investigators to study the nature and genetics of drug resistance mechanisms to a given agent, patterns of cross resistance and the mode of action of drugs. at the beginning the continuous drug exposure was chosen as a standard procedure to produce drug— resistant strains of p. falcipa...

Cancer is caused by aberrant genetic and epigenetic changes in genes expression. DNA methylation, histone modification, and microRNAs gene deregulation are the most known epigenetic changes in different stages of cancer. Since every tumor has its own specific epigenome, any abnormal pattern is a potential biomarker for classification of different types of tumors. Despite, tumorigenesis, abnorma...
