introduction: hyperthermia created by microwave (mw), infrared, ultrasound and other methods, is often utilized as an adjuvant to sensitize cancer cells to the effects of chemotherapy and radiation therapy. we investigated the efficacy of hyperthermia using mw in synergy with chemotherapy in the presence and absence and gold nanoparticles (gnps). material and methods: after culturing and prolif...

phosphorus (p) is one a nutrient elements for plant growth. in most soils has complex behavior and forms sparingly soluble compounds with soil particles. phosphorus bioavailability can be controlled by soil biological activities for optimum nutrition of plants. this study was carried out in order to isolation of p-solubilizing bacteria (psb) as well as p-solubilizing fungi (psf) and their scree...

in this study, precipitated calcium carbonate (pcc) was modified using cationic starch, and its effect on optical and physical properties of paper was examined in comparison with unmodified filler afterwards. to determine the filler retention in paper, both modified and unmodified fillers were added to pulp suspensions by 20, 30, and 40 percentages. for comparing the utilization effect of modif...

abstract background and aims: multiple sclerosis (ms) is defined by the presence of inflammatory demyelinating plaques in the central nervous system (cns). it has been indicated that human herpes virus 6 (hhv-6) may play role in pathogenesis of ms. the aim of this study was to determine the presence of hhv-6 dna and anti hhv-6 igg in ms patients and controls. materials and methods: blood sample...

to compensate for some inferior properties of recycled papers, application of processing chemical aids such as chitosan can be quite effective in the wet end section of papermaking. in this study, the performance of chitosan biopolymer, individually or associated with nanobentonite was investigated as wet end additive on recycling process of white cuttings. for this purpose, the performance of ...

introduction: patients with schizophrenia characteristically exhibit cognitive deficits. the level of cognitive impairment is found to predict the functional outcome of the illness more strongly than the severity of positive or negative symptoms. the purpose of this study was to assess the efficacy of ondansetron, a 5-ht3 receptor antagonist as an adjuvant agent in the treatment of chronic schi...
