Article history: Received 22 December 2016 Accepted 27 December 2016 clinically relevant increase in theQT interval, especially in consideration that these were LQTS patients, and thus expected to have a prolonged QT intervals to begin with. As analogy, the guidelines for LQTS indicate that whenever mexiletine shortens the QTc by at least 40 ms it should be added to beta-blockers for chronic th...

background: synthetic dyes have several harmful effects on human health as well as aquatic life. in this study, activated carbon (av-ac), based on aloe vera leaf shells, was used as a novel agricultural adsorbent, one that is low-cost and available for the removal of congo red (cr) as a carcinogenic dye from aqueous solutions. methods: in the batch system, the influence of different parameters ...

background : an outbreak investigation was carried out to determine the cause and confirm the source of food poisoning in deptsang village for implementing prevention and control measures. methods : we conducted a retrospective cohort study for the outbreak investigation. stool specimens were collected from cases to perform culture and antibiogram. the team also inspected the environment and hy...

in the present work, the znfe2o4 nanoparticle has been successfully synthesized. the obtained sample was characterized by x-ray diffraction (xrd), emission scanning electron microscopy (fe-sem) and its optical property was examined by uv-vis spectrophotometer. fe-sem revealed that the particle size of the znfe2o4 of about 47 nm was synthesized. the photocatalytic performance under uv-vis and vi...

a kinetic-spectrophotometric procedure is reported for determination of trace amounts of ag(i). this method is based on catalytic effect of silver ion on the oxidation of congo red by potassium peroxodisulphate at ph=3.4 and 30 oc in the presence of 1,10-phenanthroline as an activator. the reaction was followed spectrophotometrically by measuring the rate of change in absorbance of congo red at...

Consider two adolescents: Person One and Person Two. Person One has never used substances and exhibits relatively few behavioral (conduct) problems. On the other hand, Person Two uses substances frequently and more commonly exhibits poor conduct. If you were to guess, which of the individuals would you expect to have lower overall judgment and self-regulation? If you answered Person Two, your i...

sickle cell disease is a genetic haemoglobinopathy with consequent haemolysis and anaemia. it is of interest to study its effect on red cell indices beside haemoglobin concentration.the objective of the study is to determine the values of red cell indices in preschool-age children with sickle cell anaemia.we conducted a cross-sectional study including 97 children with sickle cell anaemia aged s...

there are reports from different countries that some types of glaucoma are associated with blood groups. this cross-sectional study was performed on 400 glaucomatous patients [100 patients in each group of primary open angle glaucoma (poag), chronic angle closure glaucoma (cacg), pseudoexfoliative glaucoma (pexg) and primary congenital glaucoma (pcg)] and 400 blood donors as control group to as...

a total of 1695 blood samples collected from ten ethnically distinct populations of iran (turks and kurds of rezaieh, lurs, aabolis, baluchis, turks and kurds of shrvan, zoroastrians, tehranis, and kermanis) were examined for six polymorphic red cell enzyme systems, namely red cell acid phosphatase (ap), adenylate kinase (ak), phosphoglucomutase (pgm1), esteraxe d (esd), adenosine deaminase (ad...
