the kinetics and mechanisms of the substitution reactions of trans-[co(en)2cncl]+ with unidentate anions, , cn¯, i¯, , br¯ and scn¯ in 60% v/v dmf-h2o binary solvent at 40.0±0.2 °c were studied spectrophotometrically. an id mechanism was assigned for the replacement of chlorine by , cn¯ and i¯, an ia one for the entry of and scn¯, and a d mechanism for br¯ entry. comparing the interchange ra...
quinazolinone derivatives are essential units in a wide range of relevant pharmacophores with a broad spectrum of abilities. due to their wide range of pharmacological and therapeutic activities including anticonvulsant, anti-inflammatory, hypolipidemic, anticancer, and anti-ulcer, the synthesis of quinazolinone moieties as a privileged class of fused heterocyclic compounds, have received much ...
COVID-19 pandemic has led to many mortalities since the beginning of 2020. As there was no previous experience, no specific therapy was used, except for gloves, masks, special clothes, and antiseptics. So various pharmacologic and non-pharmacological treatments were tried. World Health Organization published therapeutic protocols in the first weeks of the pandemic that has been changed over mo...
objectives: anticonvulsant drugs can cause various forms of skin drug reactions, ranging from exanthema to severe blistering reactions. some studies have reported an association between hla-b*1502 allele and severe skin reactions. materials and methods: fifteen patients with severe skin reactions following treatment with anticonvulsant drugs (carbamazepine, lamotrigine, phenobarbital, primidone...
Introduction: Stuttering is a disorder associated with many social and social consequences for those who stutter. Regarding the decisive role of social reactions in exacerbating or reducing many psychological problems such as stuttering and the culture-related nature of social behaviors, this study was conducted to assess social reactions affecting the severity of stuttering among Iranian adult...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
severe adverse drug reactions are an important cause of childhood morbidity and mortality. despite this, few reports in the literature describe it. this study was designed to evaluate the admitted pediatric patients due to adverse drug reactions. this retrospective study was conducted at pediatric ward of besat hospital. the records of hospitalized patients that admitted with diagnosis of adver...
Background: Administration of phenytoin can been associated with severe adverse reactions such as hypersensitivity reactions. Lymphocyte transformation test (LTT) can be a useful method for determination of the drug, which has caused hypersensitivity reaction. This study was done to evaluate the results of lymphocyte transformation test in patients with delayed hypersensitivity reactions foll...
