background: radiolabeled polyclonal human immunoglubins are useful in the detection of inflammations. in this work a novel approach has been presented to use thallium-201 as a comlexed nuclide for the development of radioimmunoconjugates. materials and methods: thallium-201 (t1/2=3.04 d) in tl+ form was converted to tl3+ cation in presence of o3 in 6m hcl, controlled by rtlc/gel electrophoresis...

a new polyvinyl choloride (pvc) membrane sensor for cerium (iii) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22dd) as an ionophore. the sensor exhibites a linear concentration range of 1.0×10-6to 1.0×10-1m, with a nernstian slope of 18.0±1.0 mv/decade, and a detection limit of 9.7×10-7m. it has a fast response time (5 s) and can be used for two mont...

objective: adaptation of the pharyngeal airway space does occur after different surgical strategies of class iii patients including mandibular setback, maxillary advancement and bimaxillary surgery. the aim of this study is to conduct a detailed cephalometric evaluation of the alterations taking place in the morphology of the pharyngeal airway space after treatment of class iii skeletal deformi...

atopic eczema (ae) is a chronic inflammatory skin disease that affects children and adults, and alters quality of life with a high morbidity rate and severe economic burden. the objective of the present work was to analyse specific atmospheric pollutants (o3, no, pm10 and so2) affecting the prevalence of diagnosed ae and its symptoms among 6-7-year-old schoolchildren. the participants included ...

     In this study a new simple selective and sensitive spectrophotometric procedure for determination of Fe(III) is described. It is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for Fe(III). After mixing sample and reagent, and incubating at the room temperature, Fe(III)-ethyl maltol complex was extracted with different ...
