hemolysis in patients exhibiting a concurrent acute-phase reaction as indicated by increases in C-reactive protein. The sensitivity of haptoglobin at a cutoff of 250 mgfL, however, is somewhat less than in situations where only hemolysis is present (2). Nonetheless, it is apparent that the decline in serum haptoglobin concentrations, owing to its complexing with hemoglobin and eventual removal ...

A microbore continuous-flow analyser was used to determine ammonia, nitrite, nitrate and phosphate in seawater. Ninety samples per hour were measured by optimizing the hydraulic conditions and using a cadmium coil for nitrate reduction. The analysis range was extended and the detection limit was reduced by using two analytical ranges with automatic range-changing. Interference from magnesium on...

       Purpose of this study was to investigate the effect of the presence of the water soluble polymers viz HPMC, PVP and PEG 6000 on aqueous solubility and complexation abilities of felodipine with or without presence of β-cyclodextrin (βCD) and HPβCD by phase solubility studies. The data revealed the initial increase in drug solubility followed by plateau in t...

Natural cases of dealloying or stress-corrosion cracking in copper alloys normally occur in oxygenated solutions, where the cathodic reactant is O2 or Cu2+. Within cavities or under deposits, the local environment is enriched in cuprous ions (e.g. CuCl2-, Cu (NH3)2+) and the potential is close to the Cu/Cu+ equilibrium. Such conditions can be simulated macroscopically by stirring powdered Cu2O ...

Introduction Mutations M680I, M694V and V726A of Pyrin the product of MEFV gene are localized at the domain B30.2 (PB30.2D) and responsible for manifestation of the most widespread and severe forms of FMF. From the other hand, it is well known that malfunction of the pyrin-caspase-1complex is the main reason for inflammation during FMF. Therefore, we suggest that comparative investigation of no...

Cobalt, nickel and copper complexes of adenine and guanine, as nucleic-acid constituents, were prepared. The adenine and guanine complexes are of tetrahedral and octahedral geometries, respectively. All are of high spin nature. The nickel complexes are of 2:1 metal:ligand ratio with Ni...Ni direct interaction in the guanine complex. The coordination bonds of adenine metal complexes are calculat...
