essential oils (eos) extracted from aerial parts of aster indamellus grierson, calamintha umbrosa benth. and erigeron annuus (l.) pres.were analyzed by gc, gc/ms. the major acetylenic constituent (cis-lachnophyllum ester) of e. annuus was isolated and characterized by 1h and 13c-nmr spectra. their toxicity and repellent effect against lipaphiserysimi was tested. oils of e. annuus and c. umbrosa...

in this article, a mathematical model describing the growth orterminating myelogenous leukemia blood cancer's cells against naive t-celland eective t-cell population of body, presented by fractional dierentialequations. we use this model to analyze the stability of the dynamics, whichoccur in the local interaction of eector-immune cell and tumor cells. wewill also investigate the optima...

over the last decade, coinciding with the growth of information and communication technologies, globalization expansion and consequently increased awareness of citizens, communities’ dissatisfactions over the lack of accountability, lack of transparency and centralized government structure is leading to the emergence of the new approach called e-governance. e-governance, against e-government by...

UNLABELLED Hepatitis E viral (HEV) infection imposes a heavy health burden worldwide and is common in the United States. Previous investigations of risks addressed environmental and host behavioral/lifestyle factors, but host genetic factors have not been examined. We assessed strength of associations between antibody to HEV (anti-HEV) immunoglobulin G seropositivity indicating past or recent H...

The aim study antibacterial effects of silver nanoparticles against resistant strains of E.coli bacteria.12 strains of E. coli strains arising urinary infection were isolated from hospitalized patient in zabolhospitals. Minimum inhibitory concentration of winter cherry were determined by dilution method in various concentration on bacteria. The highest MIC values was found to be 100ppm against ...

Objective(s): The Botulism syndrome is caused by types A to G of botulinum neurotoxins. The binding domains of these neurotoxins are immunogenic and considered as appropriate candidate vaccines. Due to the low immunogenicity of recombinant vaccines, there have been many studies on the use of biocompatible carriers such as chitosan nanoparticles for the delivery of these vaccines. The aim of thi...

Background and Objective: Gram-negative pathogens are considered the common cause of wound infections associated with increased mortality and morbidity rates. Antibiotics combination has been used to overcome this problem. Aims: In this study, we identify Gram-negative pathogens found in wound infections and assess the in-vitro efficacy of a combination of amikacin and imipenem against the resi...

BACKGROUND Human skin is able to mount a fast response against invading microorganisms by the release of antimicrobial proteins such as the ribonuclease RNase 7. Because RNase 7 exhibits high activity against Enterococcus faecium the aim of this study was to further explore the role of RNase 7 in the cutaneous innate defense system against E. faecium. METHODOLOGY/PRINCIPAL FINDINGS Absolute q...
