a method for the degradation of pyrrolidine in water is described. the method relaies on the photocatalytic degradation of pyrrolidine to co2 and nh3 by uv irradiation and using titanium dixide semiconductor as a photocatalyst. compared with direct photolysis, the semiconductor catalytic photolysis gave consistently higher degradation yields for pyrrolidine in water. the effects of variable par...

We describe an improved method for the quantitation of total and direct bilirubin in serum in which sodium dodecyl sulfate is used as an accelerator. Viscous and caustic reagents are not needed, and the effects of protein matrix, hemoglobin interference, and turbidity are minimized. For total bilirubin determination we first add the sodium dodecyl sulfate reagent to serum, then a diazo reagent ...

AIM To characterize the numbers of reagent strips dispensed for self-monitoring of blood glucose to patients with Type 2 diabetes in Tayside, Scotland, in 1993, 1999 and 2009. METHODS A diabetes clinical information system in Tayside, record-linked to electronic dispensed prescribing records, was used to collate all dispensed prescribing records for three cross-sectional samples of patients w...

Sensitive nucleic acid based detection methods such as in situ PCR, in situ RT-PCR and PRINS have great potential in the areas of developmental biology, pathogenesis and diagnostics. However, control of evaporation from in situ reactions is critical to ensure reliable data. Self-Seal Reagent, a component added directly to the in situ reaction mixture, effectively controls evaporation during in ...

The rabbit is customarily used for the preparation of anti-human globulin serum, but there are several objections to the choice of this animal. These are: (1) The volume of serum obtained is small. To maintain supplies it is necessary either to have several animals producing the reagent, or to hyperimmunize and bleed the rabbits used too frequently, which in turn results in a less specific reag...

Received for publication 8 December 1965. reduced copper is oxidized to cupric ions by means of iodine. If no necessary allowance has been made, the cupric ions formed would be completely reduced and precipitated as cuprous iodide in the presence of an excess of soluble iodide in the reagent. Probably to check this reduction by iodide, Harding and Downs (1933) employed potassium oxalate in thei...
