The effect of the potent antitumor antiobiotic Adriamycin (ADM) on DNA replication and unscheduled DNA synthesis in cultured rat cardiac cells was investigated. Autoradiography and [3H]thymidine incorporation studies were carried out on parallel cultures. DNA replication was depressed for up to 6 days following a 3-hr pulse of ADM administration. An ADM concentration of 1 microgram/ml which was...

BACKGROUND Microbial biofilms pose a public health problem for persons requiring indwelling medical devices, as micro-organisms in biofilms are difficult to treat with antimicrobial agents. Thus the present study includes biofilm formation and antibiotic resistance pattern of uropathogens in hospitalised patients with catheter associated urinary tract infections (UTI). METHOD This prospective...

Salmonella enterica is a gram-negative, rod shaped bacillus, which inhabits the intestines of mammals, reptiles and birds. In the United States, Salmonella is one of the leading causes of food-borne illness, and is typically acquired through the consumption of contaminated food or water. Modern public health practises have lead to a decrease in the number of Salmonella infections, however, ther...

The thiazole antiobiotic, thiostrepton, has been found to induce cell death in cancer cells through proteasome inhibition. As a proteasome inhibitor, thiostrepton has also been shown to suppress the expression of FOXM1, the oncogenic forkhead transcription factor overexpressed in cancer cells. In this study, we explored the potential in vivo anticancer properties of thiostrepton, delivered thro...

this research was performed to determine the efficiency effect of sedimentary environment of kerman city area on soil structure bycomparing natural and reconstituted consolidation curves. in this regard, four different criteria such as sensitivity strength, stresssensitivity, schmertman criteria and the result of the uniaxial compression test were used. the base of these criteria is to compare ...

Digestion of grande mitochondrial DNA (mtDNA) BY EcoRI restriction endonuclease gives rise to nine fragments with a total molecular weight of 51.8 x 10(6). HindIII digestion yields six fragments with a similar total molecular weight. Specific restriction fragments can be detected despite the fact that yeast mtDNA consists of a heterogeneous distribution of randomly broken molecules. Digestion p...
