We describe a new high-performance liquid chromatography (HPLC) method for measurement of midazolam and its major metabolite, alpha-hydroxymidazolam, in clinical samples. Plasma or urine was mixed with 100 ng internal standard Ro 05-6669 and borate buffer, 0.1 M, pH 9. Midazolam and its related compounds were extracted into diethylether. The organic phase(More)
This manuscript describes the design considerations, implementation, and laboratory validation of an odor sensing module whose purpose is to support people that suffer from incontinence. Because of the requirements expressed by the affected end-users the odor sensing unit is realized as a portable accessory that may be connected to any pre-existing smart(More)
A rapid, sensitive and specific high-performance liquid chromatographic assay was developed for the determination in plasma of (E)-1,2,3,4-tetrahydro-1,1,4,4-tetramethyl-6-(1-methyl-2- phenylethenyl)naphthalene (1) and its phenolic metabolite (E)-4-[2-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl)-2- methylethenyl]-phenol (2). An extraction(More)
In order to take full advantage of novel functional materials in the next generation of sensorial devices scalable processes for their fabrication and utilization are of great importance. Also understanding the processes lending the properties to those materials is essential. Among the most sought-after sensor applications are low-cost, highly sensitive and(More)
