In this research, for the first time in Iran, Deferoxamine test for differential diagnosis between Staph. epidermidis and Staph. hominis of other gram­positive cocci is introduced. Besides, the comparative results of the susceptibility rates of Staph. aureus (220 Spp.) and Enterococci ( 110 Spp.) to a new glycopeptide antibiotic (SK&Fl04662) and other 12 antibiotics are presented by Disk-Agar D...

We investigate the distribution of eigenvalues of completely nuclear maps on an operator space. We prove that eigenvalues of completely nuclear maps are square-summable in general and summable if the underlying operator space is Hilbertian and homogeneous. Conversely, if eigenvalues are summable for all completely nuclear maps, then every finite dimensional subspace of the underlying operator s...

The oxygen-resistant strain of Chlorella sorokiniana (Shihira and Krauss), distinguished by its ability to grow autotrophically under high partial pressures of oxygen, was studied and partially characterized in heterotrophic culture. Ultrastructural analysis of glucose-grown oxygen-resistant strain and wild type cells reveals that osmiophilic deposits (possibly polyphosphate) are present only i...

conclusions in the present study, we found a high prevalence of mrsa at the hospitals studied. the findings emphasized the increased prevalence of mrsa isolates containing different toxin and adhesion genes, probably accompanied by antimicrobial resistance. infection with such isolates worsens the clinical outcomes as well as the morbidity and mortality rates in hospitalized patients in icus. m...

melon and musk melon are grown widely in warm and moderate climate regions of the world as well as iran. these crops are attacked by several fungal pathogens including macrophomina phaseolina which causes charcoal rot disease at different growth stages and reduces the yield remarkably. fungicide application and other control methods have not been successful in control of charcoal rot and utiliz...

Melanoma harboring BRAF mutations frequently develop resistance to BRAF inhibitors, limiting the impact of treatment. Here, we establish a mechanism of resistance and subsequently identified a suitable drug combination to overcome the resistance. Single treatment of BRAF mutant melanoma cell lines with vemurafenib or dabrafenib (BRAF inhibitors) alone or in combination with trametinib (MEK1/2 i...

The objective of our study was to compare the effects electron beam irradiation on development and reproduction Tetranychus urticae strains that were susceptible or resistant acequinocyl, bifenazate, etoxazole. Electron (50–400 Gy) applied T. eggs, nymphs, adults, after which hatching rate, emergence longevity, fecundity analyzed. Eggs all irradiated with 150 Gy, none them hatched. When protony...

Newly synthesized quinoline derivatives were investigated for their efficacy to reverse multidrug resistance (MDR). In this study, one of the most effective quinoline derivatives, MS-073, was compared with verapamil with regard to its ability to overcome MDR in vitro and in vivo. MS-073 at 0.1 MMalmost completely reversed in vitro resistance to vincristine (VCR) in VCR-resistant P388 cells. The...
