background extended-spectrum β-lactamase (esbl)-producing klebsiella pneumonia has become widespread in hospitals and is increasing in community settings. most of k. pneumonia that harbor these enzymes, display resistance to other unrelated antimicrobial agents and thus, often pose a therapeutic dilemma. objectives this study was conducted to determine the prevalence of esbl-producing k. pneumo...

dermatophyte fungi are the etiologic agents of skin infections commonly referred to as ringworm. these infections are not dangerous but as a chronic cutaneous infections they may be difficult to treat and can also cause physical discomfort for patients. they are considered important as a public health problem as well. no information is available regarding the efficacy of antifungal agents again...

bacterial resistance to antibiotics is a serious problem and is increasing in prevalence world-wide at an alarming rate. the antimicrobial susceptibility patterns of 1897 gram-positive bacterial isolates were evaluated. the minimum inhibitory concentration (mic) of isolates which comprised staphylococcus aureus (927 isolates), coagulase-negative staphylococci (cns; 425 isolates), enterococcus f...

in the first part of this work, correlation between optical activity and elements of magnetic susceptibility tensor (mst) for five classes of model small molecules containing a single chiral center has been studied using quantum computational techniques at dft-b3lyp level of theory with 6-311g basis set. several molecular properties are used to reduce the mst elements prior to the examination o...

background and objectives: this study was designed as a retrospective study on urine samples during three years in shaheed mostafa khomeini hospital to determine demographic characteristics of patients with urinary tract infection (uti), microbial etiology, and susceptibility of isolated bacteria to antibiotics. materials and methods: all urines fulfilling the criteria for significant bacteriur...

we will present a detailed investigation of intersubband transitions process in core-multi shells quantum dots. the confined wave functions and eigenenergies of electrons in quantum dots have been calculated under the effective-mass approximation by solving a three-dimensional schrodinger equation. excellent dependence is found between size effects, time relaxation and degenerate four wave mixi...

background: in turkey, vector control programs are mainly based on indoor residual spraying with pyre­throids against mosquitoes. no special control program is available for sand flies. most insecticide susceptibil­ity tests were done for mosquitoes but not for sand flies. we therefore aimed to determine the insecticide susceptibility against two commonly used insecticides; deltamethrin and per...

background: this study was designed to detect whether there is a correlation between in vitro susceptibility of field isolates of leishmania major and the clinical outcomes of meglumine antimoniate (glucantime®) therapy, the main­stay of cutaneous leishmaniasis treatment in iran. methods: forty-three patients infected with l. major were enrolled in this study from october 2009 to march 2010 and...

introduction: it has been shown that low levels of pigmentation increase susceptibility to noise-induced hearing loss in humans. for this reason, white populations develop more pronounced noise- induced hearing loss in comparison to black populations. similarly, blue-eyed individuals exhibit greater temporary threshold shift than brown-eyed subjects; still, no strong correlation has been verifi...
