A simplified, rapid, selective HPLC method for determining five cytochrome P450 (CYP) probe drugs in single run is described. The five specific probe substrates of caffeine, chlorzoxazone, tolbutamide, metoprolol and midazolam, together with the internal standard diazepam, were...
The depleting petroleum storage and increasing environmental deterioration are threatening the sustainable development of human societies. As such, biofuels and chemical feedstocks generated from renewable sources are becoming increasingly important. Although previous efforts...
Inappropriate prescribing (IP) in older patients is highly prevalent and is associated with an increased risk of adverse drug events (ADEs), morbidity, mortality and healthcare utilisation. Consequently, IP is a major safety concern and with changing population demographics, it...
The principle behind ionic liquids and why they can be used to replace acids and organic solvents.
Welders, Iron Workers and Dairy Farmers are ranked in CNN's five worst jobs due to unfavourable working conditions, pay and future prospects.
The fictional Retro Encabulator device, which uses six hydrocoptic marzel vanes and an ambifacient lunar wane shaft to prevent unwanted side fumbling. We can't believe the salesman was able to keep a straight face.
Boeing is racing a hydroplane that uses a 50/50 blend of sustainable biofuel and jet fuel.
While rare-earth magnets are very efficient at removing unwanted contamination, they can be very dangerous to maintenance personnel if not handled properly.
Flow-injection determination of retinol and tocopherol in pharmaceuticals with acidic potassium permanganate chemiluminescence.January 19, 2010 6:38 pm | by Anal Sci | Articles | Comments
A simple and rapid flow-injection method is reported for the determination of retinol, its derivatives and alpha-tocopherol by its enhancement effect on a potassium permanganate-formaldehyde chemiluminescence system in an acidic medium. Linear calibration graphs were obtained...
Sulfadiazine-potentiometric sensors for flow and batch determinations of sulfadiazine in drugs and biological fluids.January 19, 2010 6:38 pm | by Anal Sci | Articles | Comments
New PVC membrane electrodes for the determination of sulfadiazine (SDZ) are presented. The electrodes are fabricated with conventional and tubular configurations with a graphite-based electrical contact, and no internal reference solution. The selective membranes consist of...
