chronic granulomatous disease (cgd) is a rare inherited disorder characterized by inability of phagocytes to generate oxygen radicals needed for intracellular killing of phagocytic microorganisms. we report a 2.5-year-old iranian female with multiple liver abscesses. she was admitted in surgical ward because of abdominal pain and fever for one month duration that had no response to conventional...

we have evaluated the nmr shielding tensors for active site of oxidized ayurin azurin is classified to atype i copper protein with et functionality. we have computed nmr shielding tensor at .133lyp and idlevels by usum 6-3ig basis set in the gas phase and in different solvents such as water, hmso,nitromethane, methanol, ethanol, acetone ,dicholoroethane. these solvents represent a wide range of...

Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...

poly urea-formaldehyde was synthesized simply and rapidly from urea and formaldehyde by condensation polymerization and studied for the sorption of trace acid blue from aqueous solution. the optimum ph value for sorption of the acid blue was 4. experimental results showed that the sorption capacity of poly urea-formaldehyde for acid blue was determined. the synthetic polymer can be reused for 5...

the size composition, growth pattern, sex ratio and feeding habits of the blue swimming crab, portunus segnis from persian gulf in south of iran, was studied. sampling was performed by trawl net during a one- year period (july 2011 to may 2012) as processed 864 crabs was collection. the crabs carapace width ranged were from 7.5-17.5 cm for males and 7.0-16.5 cm for females. the crab carapace le...

a simple, rapid and sensitive method has been developed for determination of trances of tellurium (vi) (0.096-1.250 mg/ml) based on its catalytic effect on the reduction reaction of toluidine blue by sulfide ion at ph 4. the reaction is monitored spectrophotometrically by measuring the decrease in absorbance of the dyestuff at 628 nm by the fixed time method. the detection limit is 80 ng/ml and...

blue rubber bleb nevus syndrome is a rare disorder that is characterized by multiple recurrent vascular malformations of skin and gastrointestinal tract . the affected patients may present with diverse manifestations including iron deficiency anemia. we report this syndrome in a 22-year-old man that was referred to our hospital for iron deficiency anemia with unknown cause and vascular malforma...

introduction: textile industries produce large volume of colored dye effluents which are toxic and removal of dyes from wastewater is a significant environmental issue. advanced oxidation process (aops) is alternative method for the complete degradation many organic pollutants. zno and tio2 are important photocatalysts with high catalytic activity that have attracted much research attention. ma...

due to universal importance of tabriz carpet art and presence of specific indicators and motifs in tabriz carpet art and its potentials, existence of architectural site for representing this art as carpet art museum in tabriz is necessary. the site of this project is located adjacent to tabriz blue mosque near the museum historical site. it is essential to consider the historical elements and c...

introduction: development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. blood brain barrier (bbb) opening is an important part of edema named as vasogenic brain edema. in this study, quantitative alterations of bbb permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. methods: two groups of male rats (ischemic and sh...
