patients with acute myeloblastic leukemia (aml) with monosomy 7 are a group of patients with refractory aml who have a very poor prognosis. therefore, rationally designed new therapies, including metronomic chemotherapy regimen with histidine deacetylase inhibitors (valporic acid, atra) are being investigated as potential treatments for the population of refractory cases of aml. herein, we repo...

dyke-davidoff-masson syndrome (ddms) is a syndrome associated with refractory epilepsy. ddms is a rare syndrome characterized by seizures, facial asymmetry, contralateral hemiplegia and mental retardation. the characteristic radiologic features are cerebral hemiatrophy with homolateral hypertrophy of the skull and sinuses. the case was an 18 years old female with seizures, hemiparesis of the ri...

the term biomining have been coined to refer to the use of microorganisms in mining processes as in the biooxidation of refractory gold minerals. the biooxidation of refractory gold ores presents similar characteristics when compared with roasting and pressure oxidation. almost without exception, microbial extraction procedures are more environmentally friendly. the isolated bacteria in this st...

objective the lennox-gastaut syndrome (lgs: the triad of intractable seizures of various types, a slow spike-wave pattern in eeg and mental retardation) is one of the most difficult epilepsy syndromes to treat. the aim of this study was to evaluate the efficacy and safety of zonisamide (zns) as add-on therapy in seizures of children with lgs. materials & methods in a quasi- experimental study, ...

Silica refractory bricks are used especially in the metallurgical industries, due to desirable properties such as particularly their high melting point and their rigidity and strength at high temperatures. In this research, different amount of SiC were added to Silica refractory containing different binders such as Borax, Boric acid, Calcium nitride, Sodium tri poly phosphate, Sodium hexametaph...

objective epilepsy occurs with a yearly incidence of 40 per 100,000 children, of which more than 25% are resistant to drug therapy. epilepsy may occur in autoimmune diseases like lupus, celiac disease and myasthenia gravis. in this study, the relationship between celiac disease and refractory epilepsy was evaluated in children with idiopathic epilepsy. material & methods hundred-fifty-five chil...

objective 1-3% of the population suffer from epilepsy. up to 30% of them develop refractory epilepsy and their seizures occur more than once per month despite receiving at least 2 first line antiepileptic drugs. in  this group, more efficacious antiepileptics are needed. this study was undertaken to evaluate the efficacy and safety of oxcarbazepine as an adjunction therapy in children with refr...

Background and aim: Treatment of resistant warts is a common clinical problem. Immunotherapy with diphenyl cyclopropenone (DCP) as a contact sensitizer has been reported. The objective of this study was to evaluate the efficacy of DCP in refractory warts.Materials and methods: Nineteen patients with refractory warts referred to Razi Hospital in 2004 who had not responded to at least 2 treatment...

A change in subtask order in the psychological refractory period (PRP) paradigm increases the effect of stimulus onset asynchrony (SOA) on the second response. We used a paradigm with cued, randomly determined subtask order to test the hypothesis that this SOA by order switch overadditivity reflects order control, via "copying" stimulus order. In Experiments 1a and 1b, overadditivity was eviden...

introduction biotinidase deficiency is a life threatening inborn error of metabolism specially when delayed in diagnosis. we report a 2-month-old male infant that presented with refractory infantile spasm, alopecia and seborrheic dermatitis. with a high suspicion of the biotinidase deficiency we started biotin 10 mg daily orally before definite diagnosis was made. rapid treatment was life-savin...
