pH-enzyme di-dependent chronotherapeutic drug delivery system of theophylline for nocturnal asthma.
The purpose of this research work was to develop and evaluate a chronotherapeutic based colon-targeted drug delivery system of theophylline (THEO) exploiting pH-enzyme sensitive property for the prevention of episodic attack of asthma in early morning. Guar gum microspheres of theophylline were prepared by emulsification technique. Coating of microspheres was performed using solvent evaporation...
متن کاملHomogeneous enzyme immunoassay for theophylline with a centrifugal analyzer.
A rapid homogeneous enzyme immunoassay for theophylline has been adapted to a centrifugal analyzer. The sample volume used was 10 microliter and sera from as many as 28 patients could be measured in 180 seconds. The assay temperature was 30 degrees and the absorbance rates were measured at 340 nm. Within-run and run-to-run precision showed a coefficient of variation of less than 2.6 and 7.5 per...
متن کاملABC of monitoring drug therapy. Theophylline.
It is not possible to establish a single dosage regimen for theophylline or its derivatives (for example, aminophylline) that will suit all patients because the metabolism of theophylline varies greatly from person to person. This variation is reflected in its elimination half life, which varies from four hours in healthy adult smokers to about 25 hours in patients with hepatic cirrhosis. Sever...
متن کاملEffect of serum on an RNA aptamer-based electrochemical sensor for theophylline.
Electrochemical performance of the ferrocene (Fc) redox-labeled RNA aptamer based sensor for theophylline (Th) is essentially inhibited in serum, but is restored in serum-free buffer solutions. This phenomenon is inconsistent with the data on methylene-blue-labeled aptamer beacon systems, which operational potential window is more negative compared to the Fc redox label. Electrochemical studies...
متن کاملAn Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks
LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
