abstract background: the functions and use of mouthwashes are variable depending on their type. oral care in patients with endotracheal tubes is important to prevent side effects such as pneumonia. the aim of this study was to determine the antimicrobial effects of chlorhexidine, drop of matrica mouthwash (chamomile extract), and normal saline on hospitalized patients with endotracheal tube in ...

objective(s):urinary tract infection (uti) caused by bacteria is one of the most frequent infections in human population. inappropriate use of antibiotics, often leads to appearance of drug resistance in bacteria. however, use of probiotic bacteria has been suggested as a partial replacement. this study was aimed to assess the antagonistic effects of lactobacillus standard strains against bacte...

screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. actinomycetes have the capability to synthesize manydifferent antibiotics. a total of 69 actinomycete isolates were recovered from soil samplescollected from alborz province. selected colonies (rough, chalky) of actinomycetes werepurified. all screened isolates were iden...

background: avian pathogenic escherichia coli (apec), which is the causative agent of colibacillosis, harbors several putative virulence genes. an important trait of apec for both poultry and public health is antibiotic resistance. objectives: in the present study, some potential virulence genes of apecs isolated from northeast of iran and their resistance to the quinolones antibiotics were stu...

Multicellular organisms live in environments containing diverse nutrients and a wide variety of microbial communities. On the one hand, immune response can protect from intrusion exogenous microorganisms. other dynamic coordination anabolism catabolism is necessary factor for growth reproduction. Since production an energy-intensive process, activation cells accompanied by metabolic transformat...

Far infrared radiation (FIR) is currently investigated as a potential therapeutic strategy in various diseases though the mechanism is unknown. Presently, we tested if FIR mediates beneficial effects in a cell model of the neurodegenerative disease spinocerebellar ataxia type 3 (SCA3). SCA3 is caused by a mutation leading to an abnormal polyglutamine expansion (PolyQ) in ataxin-3 protein. The c...

That's not only this book gives reference, but also it will show you the amazing benefits of reading a book. Developing your countless minds is needed; moreover you are kind of people with great curiosi...

The Choice Between Fixed and Random Effects Models: Some Considerations for Educational Research We discuss fixed and random effects models in the context of educational research and set out the assumptions behind the two approaches. To illustrate the issues, we analyse the determinants of pupil achievement in primary school, using data from the Avon Longitudinal Study of Parents and Children. ...

avian pathogenic e. coli (apec) is responsible for economic losses in all poultry farms. certain virulence factors have been proposed as a means of controlling apec infections, including some proteins to be used for vaccination. in the study we report here, one of the major virulence factors, the iss (increased serum survival) gene, from e. coli strain χ1378, isolated from poultry colibacillosi...

background: colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. objectives: in order to evaluate molecular epidemiologyof some virulence associated factors in escherichia coli,isolated from poultry, the presence of iut a, iss, hly f, omp t, iron, afa, sfa (s)and pap g (ii) were investigated by multiplex pcrassay. methods: two hundred th...
