A fluorimetric assay for metolazone in urine.

The fluorimetric determination of riboflavin in urine.

Fluorimetric coupled enzyme assay for lysoplasmalogenase activity in liver.

We developed a continuous spectrofluorimetric assay of lysoplasmalogenase activity with the use of horse liver alcohol dehydrogenase as a coupling enzyme. In this method the disappearance of NADH is measured spectrofluorimetrically. The excitation and emission monochromators were set at 340 and 460 nm respectively. The assay is 10 times as sensitive as the previous u.v. spectrophotometric metho...

passivity in waiting for godot and endgame: a psychoanalytic reading

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...

Improved turbidimetric assay for lysozyme in urine.

I describe an improved turbidimetric assay for lysozyme in urine. This method is simple, reproducible, linear over a 100-fold concentration range, sensitive to concentrations as low as 10 micrograms/L, and only commercially available products are required. Evaluation of urinary lysozyme concentration with this assay demonstrated a within-run and between-run CV of 9.9% and 4.8%, respectively, fo...

Standardization of a fluorimetric assay for the determination of tissue angiotensin-converting enzyme activity in rats.

The tripeptide Hip-His-Leu was used to standardize a fluorimetric method to measure tissue angiotensin-converting enzyme (ACE) activity in rats. The fluorescence of the o-phthaldialdehyde-His-Leu adduct was compared in the presence and absence of the homogenate (25 microl) to determine whether the homogenate from different tissues interfered with the fluorimetric determination of the His-Leu pr...
