one of the growth limiting factors of onion plants is root and basal plate rot disease, caused by fusarium oxysporum f. sp. cepae. in this research, eight iranian onion genotypes, azarshahr red, ghom white, herssin, isfahan dorcheh, kashan white, nishabour ishaghabad, yazd abarkoh, zanjan gholigheseh and two commercial genotypes, texas erly grano and yellow sweet spanish were investigated. geno...

objective bacterial adhesion is governed by specific and nonspecific interactions such as hydrophobicity. hydrophobic interactions play a role in the adherence of microorganisms to a wide variety of surfaces and facilitate biofilm formation due to bacterial adhesion. in this article the relation between cell surface hydrophobicity and antibiotic resistance was studied. materials and methods we ...

in this study demographic, clinical, paraclinical, microbiological, and therapeutic features of patients with community-acquired acute bacterial meningitis admitted to a referral center for infectious diseases in iran, have been evaluated. medical records of adult (> 18 years) individuals with confirmed diagnosis of community-acquired bacterial meningitis during a 4-year period were retrospecti...

automobile body plays crucial role in preventing the collision energy transfer in severe accidents to the passengers. if the collision energy is dissipated or saved in bumper or chassis, the amount of damage to the occupants would be minimized. using novel laminated panel (fiber metal laminate) in auto body, and considering the characteristics such as high energy absorption, strength, high dent...

objective(s):p in vitro chemosensitivity and resistance assays (csras) are a promising tool for personalized treatment of glioblastoma multiform (gbm). these assays require a minimum of 1 to 2 g of tumor specimen for testing, but this amount is not always accessible. we aimed to assess the feasibility and validity of utilizing stereotactic biopsies of gbm in csras. materials and methods: single...

to determine the relative salt tolerance and/or resistance in seedlings of pistachio genotypes, four pot experimentswere conducted. in experiments 1 and 2, the effects of salinity on growth indices were studid. experiments were donein the form of split plot based on rcbd. in each experiment, mainplots consisted of different electrical conductivitiesof irrigation water (eciws). in experiment 1, ...

root and shoot osmotic and elastic properties of two species of haloxylon aphyllum and h.persicum in response to water stress were studied. the main goal of the study was to determine if the tissuesof two species utilize osmotic adjustment and/or enhance their elastic property during prolonged water stresscondition. the results showed that although tissue elasticity of both species of haloxylon...
