BACKGROUND Dolutegravir is approved for the treatment of HIV-1 patients exposed to other integrase inhibitors, but the decision to use dolutegravir in this setting should be informed by drug resistance testing. OBJECTIVES This study determined the extent of disagreement in predicted residual dolutegravir activity after raltegravir use, and identified individual mutational patterns for which u...
BACKGROUND Due to outdoor and residual transmission and insecticide resistance, long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) will be insufficient as stand-alone malaria vector control interventions in many settings as programmes shift toward malaria elimination. Combining additional vector control interventions as part of an integrated strategy would potentially ove...
BACKGROUND The ABL kinase inhibitor imatinib is highly effective in treating most, but not all, patients with chronic myeloid leukemia (CML). This is because residual CML cells are generally present in the bone marrow microenvironment and are refractory to imatinib. Hematopoietic cytokine receptor signaling is mediated by Janus kinases (JAKs) and their downstream transcription factor, signal tr...
Objectives: The goal of this study was to compare the effect of 8 weeks aerobic exercise with resistance training on Brain-derived neurotrophic factor level of old men. Methods & Materials: In this semi-experimental study, a total of 30 elderly men were selected from worldly-wise club of Broujen City, Iran and randomly divided into 3 groups of aerobic training, resistance trai...
There is some controversy regarding the effects of HNO3 on films of single-walled carbon nanotubes (SWCNTs). In this study we examined the change in sheet resistance of an HNO3-modified SWCNT film after different drying times at 85 degrees C using various analytical techniques. The shift and suppression in the Raman spectra, bleaching of the transition peaks related to van Hove singularities an...
We have been examining the consequences of alternative modes of regulation of plasmid-borne, Tn10-encoded tetracycline resistance for the fitness of Escherichia coli. In a tetracycline-free environment, we measured the effects on fitness that were caused by (1) maximally induced expression of the resistance operon, (2) low-level constitutive expression of the resistance protein, (3) residual ex...
This study was conducted to determine some heavy metals (Fe, Mg, Cr, Ni) of surface sediment in the southern Caspian Sea during two seasons (Summer and Winter) in 2014-2015. 36 surface sediments samples (with triplicate) were collected at two stations (Tonekabon and Bandar Amirabad). All samples were analyzed using sequential extraction to indicate natural and anthropogenic sources. The results...
Purpose. To evaluate the safety, efficacy, and predictability of photorefractive keratectomy (PRK) on the corneal flap for correction of residual myopia following myopic laser in situ keratomileusis (LASIK). Patients and Methods. A retrospective study on eyes retreated by PRK on the corneal flap for residual myopia after LASIK. All eyes had no enough stroma after LASIK sufficient for LASIK enha...
the toxicity of chlorpyrifos to three iranian populations of two-spotted spider mite, collected from isfahan (isr), yazd (yz) and guilan (gus2) provinces were surveyed using the residual contact vial bioassay. the bioassay results showed that resistance ratios of isr and yz populations were 176.90 and 9.78 fold compared to the gus2 population, respectively. determination of esterase and glutath...
