objectives: acinetobacter baumannii is a gram-negative, non-motile aerobic bacterium known as a nosocomial pathogen resisting often to broad range of antibiotics. the pathogen is a serious agent of mortality and morbidity in hospital particularly among immunocompromise patients. treatment and control of its infections is complicated owing to its high antibiotic resistance, survival in various e...

objective: breast cancer is one of the leading causes of death in women worldwide. conventional treatments use cytotoxic drugs which have high numbers of side effects. currently pharmacologists are searching for novel drugs with fewer side effects and maximum efficiency as breast cancer treatment. the aim of the current study is to clarify the cytotoxicity effect of the recombinant outer membra...

background: leptospirosis has been recognized as an important reemerging infectious disease caused by pathogenic leptospira spp. a major challenge of this disease is the application of a basic research to improve diagnostic method. outer membrane proteins of leptospira are potential candidates that could be useful in diagnosis. among them the lipl41 is an immunogenic protein which is present on...

different strains of escherichia coli (e. coli) from human, chickens, and the common strain between human and chickens were isolated and typed with mono-specific antibody. the e. coli strains from each group of human, chicken and common between human and chicken were selected. the polypeptide patterns of selected strains were analyzed and compared with each other by sodium dodecyle sulphate pol...

conclusions the results showed that the extracted omvs were conformationally stable, and there were no pyrogenic determinants in omv. also the results showed that the omv elicited high level of specific antibodies against n. meningitidis serogroup a. these results indicate that the omv obtained here, can be used as a meningococcal vaccine after further investigation. materials and methods omvs ...

three strains of nontypeable haemophilus influenzae namely nthi-i , nthi-ii and nthi-iii were isolated from the sputum of patients with bronchitis and identified by biochemical, serological and electron microscopy. the polypeptide patterns of isolates were compared and found to have similar sodium dodecyl sulphate-polyacrylamide gel electrophoresis (sds-page) polypeptide patterns, although some...

‎A Roman dominating function (RDF) on a graph G=(V,E) is a function  f : V → {0, 1, 2}  such that every vertex u for which f(u)=0 is‎ ‎adjacent to at least one vertex v for which f(v)=2‎. ‎An RDF f is called‎‎an outer independent Roman dominating function (OIRDF) if the set of‎‎vertices assigned a 0 under f is an independent set‎. ‎The weight of an‎‎OIRDF is the sum of its function values over ...

background and objective: an outer membrane protein (omp) of helicobacter pylori namely oipa, is an important vir- ulence factor associated with peptic ulcer and gastric cancer risks. the purpose of this study was to isolate the 34 kda omp of h. pylori and evaluate its immunogenicity in experimental animals for rapid detection of more virulent h. pylori isolates. material and methods: sarcosine...

To a hyperbolic smooth curve defined over a number-field one naturally associates an "anabelian" representation of the absolute Galois group of the base field landing in outer automorphism group of the algebraic fundamental group. In this paper, we introduce several deformation problems for Lie-algebra versions of the above representation and show that, this way we get a richer structure than t...
