background: acetaminophen is widely used as an analgesic and antipyretic drug and it is a frequent cause of acute drug poisoning.this study was carried out to investigate the demographic information and clinical and laboratory findings in acetaminophen poisoning patients referred to “17 shahrivar” and “razi” educational hospitals, rasht. methods: in this retrospective cross-sectional study, 125...
Horseradish peroxidase-catalyzed oxidation of p-phenetidine in the presence of either glutathione (GSH), cysteine, or N-acetylcysteine led to the production of the appropriate thioyl radical which could be observed using EPR spectroscopy in conjunction with the spin trap 5,5-dimethyl-1-pyrroline-N-oxide. This confirms earlier work using acetaminophen (Ross, D., Albano, E., Nilsson, U., and Mold...
allergic diseases are frequent in children and their prevalence and severity deffer in the different regions of the world. a number of studies have been performed to determine the factors which are effective in the incidence of these diseases. one of the drugs that might have a role in incidence or intensity of the symptoms of allergic diseases is acetaminophen. in our survey conducted with sta...
The main aim of this research is to obtain high purity potassium dihydrogen phosphate solution with Al, Cr, Fe and Ti impurity content < 0.05 ppmw (5⋅10-6 wt.%) by the simple and effective process of impurities coprecipitation with insoluble precipitants. The completeness of the coprecipitation with different coprecipitants of the above-mentioned impurities in saturated potassium dihydrogen pho...

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
The hypothesis that acetaminophen can reduce necrosis during myocardial infarction was tested in male dogs. Two groups were studied: vehicle- (n=10) and acetaminophen-treated (n=10) dogs. All dogs were obtained from the same vendor, and there were no significant differences in their ages (18 +/- 2 mo), weights (24 +/- 1 kg), or housing conditions. Selected physiological data, e.g., coronary blo...
Background: Acetaminophen is the most commonly used analgesic and fever-lowering agent that is prescribed in a high percentage of patients. Due to the high prevalence of the administration of this drug, even a small percentage of errors in prescription can be significant and have important implications. The aim of the present study was to determine the frequency of supratherapeutic dosing of ac...
