b ackground : one of the main mechanisms of resistance to carbapenems is potential of klebsiella pneumoniae to produce k . pneumoniae carbapenemase (kpc). kpc is an important type of carbapenemase, which can hydrolyze carbapenems and other beta-lactam antibiotics. modified hodge test (mht) and  use  of  boronic  acid  as  a  kpc  inhibitor  are  two  types  of  phenotypic methods, which are use...

in the present study, the onset of double diffusive reaction-convection in a uid layer with viscous fluid, heated and salted from below subject to chemical equilibrium on the boundaries, has been investigated. linear and nonlinear stability analysis have been performed. for linear analysis normal mode technique is used and for nonlinear analysis minimal representation of truncated fourier serie...

conclusions capillaria hepatica should be considered in differential diagnoses in any child with fever, hepatomegaly, eosinophilia and hyperglobulinemia. case presentation the current paper reports a case of capillaria hepatica infection in a four-year-old boy which presented with fever, hepatomegaly, peripheral eosinophilia, and noticeable weight loss. the diagnosis was made on the histologica...

qct calculations were performed to study the behavior of energized nh2oh formed by association collision of nh2 radical with oh radical. a potential energy surface that describes the behavior of the title reaction has been constructed by interpolation of ab initio data. h2o, hon, hno, nh3, o, h2no, cis or trans-honh, and h products and two vibrationally energized nh2oh and nh3o adducts were obs...

conclusions: in neonates and infants with primary diagnosis of sepsis, hsv infection should be considered especially if the clinical condition does not improve after 48 hours of antibiotic therapy, and sepsis still exists with elevated liver enzymes. results: among 150 neonates and infants younger than 3 months old with sepsis, the pcr results for detecting the hsv dna, were positive in 6 sampl...

conclusions findings of this study showed that integron can have a limited frequency in s. aureus isolated from clinical sample in tehran. results among the 200 samples, 1% of the strains (two isolates) contained the class 1 integron gene. the results of this study showed that the highest frequency of the obtained samples belonged to males and the isolates occurred mostly in individuals aged 51...

introduction : haemophilus influenzae is a gram-negative bacterium causing a variety of respiratory infections in developing countries, especially in children. nasopharynx carriers of h. influenzae are the prominent source and transitional vectors of invasive diseases. as very limited information on h. influenzae carriage rate in iran was available, an evaluation on prevalence of this bacterium...

stroke is an important cause of disability and death worldwide, with the majority of strokes occurring in older people. thrombolysis with recombinant tissue plasminogen activator (r-tpa) is the approved treatment for acute ischemic stroke. a major concern of physicians, who treat acute ischemic stroke with recombinant tissue plasminogen activator (r-tpa,) is the risk of intracerebral hemorrhage...

introduction: the aim of this animal study was to evaluate the histological response of the new nano zinc-oxide eugenol (nzoe) sealer in comparison with pulp canal sealer (zoe based) and ah-26 (epoxy resin sealer). methods and materials: a total of 27 wistar rats were used. four polyethylene tubes were implanted in the back of each rat (three tubes containing the test materials and an empty tub...

background and aims: this research aimed to study a possible link between endometriosis and polymorphism of the progesterone receptor gene. materials and methods: the control group consisted of 86 women without endometriosis and the case group comprised 86 patients with a diagnosis of endometriosis by laparoscopy. genotypes for alu insertion polymorphisms (a1/a1, a1/a2 and a2/a2) were described...
