The reaction of picric acid with creatinine in alkaline solution (Jaffe’s reaction), which is the basis of the Folin method (1) for the determination of creatinine, has been thought to be either a reduction of the acid or else the formation of a red tautomer of creatinine picrate. Greenwald (2) obtained evidence that the tautomerism involves picric acid as well as creatinine, and that other nit...

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...

This study had as objective to investigate the result and the colour gradation of red reflex test in newborns (NB). It is a exploratory, quantitative study and the sample was 180 NB from maternity ward in Fortaleza-CE. From this, 156 showed result "no altered" and 24 "suspect". About the aspect of red reflex, 144 NB showed the same coloration in the two eyes, in 35 of this, the colour was red, ...

in this study, the adsorption of hexavalent chromium and zinc ions from the solution is investigated by raw red mud and mechanical-chemical activated red mud along with the possibility of selective reclamation of these ions from the solution. the mechanical-chemical activation of red mud was done by employing high-energy milling and subsequent acid treatment with hno3. raw red mud (rrm) and mec...

preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of nile red-loaded solid lipid nanoparticles. nanoparticles (nps) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. to solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...
