Laser desorption/ionization time-of-flight mass spectrometry on sol-gel-derived 2,5-dihydroxybenzoic acid film.

Ya-Shiuan Lin et al.

Analytical chemistry, 74(22), 5793-5798 (2002-12-05)

This work presents a novel method for direct desorption/ ionization of analytes from sol-gel-derived film. 2,5-Dihydroxy benzoic acid (DHB), a common MALDI matrix, was incorporated into a sol-gel polymeric structure. The sol-gel-derived DHB thin film can assist the mass analysis

Salicylate metabolite kinetics after several salicylates.

F Bochner et al.

Clinical pharmacology and therapeutics, 30(2), 266-275 (1981-08-01)

Single oral doses of aspirin (ASA, 1,500 mg), sodium salicylate (NaSA, 1,500 mg, 1,200 mg), and salicyluric acid (SUA, 500 mg) were given to five subjects. Serial plasma and urine samples were collected for 24 hr (plasma) and up to

Simultaneous liquid-chromatographic quantitation of salicylic acid, salicyluric acid, and gentisic acid in urine.

B E Cham et al.

Clinical chemistry, 26(1), 111-114 (1980-01-01)

We have developed a specific and sensitive method for the determination of salicylic acid, salicyluric acid, and gentisic acid in urine. Any proteins present are precipitated with methyl cyanide. After centrifugation, an aliquot of the supernate is directly injected into

Subventricular zone lipidomic architecture loss in Huntington's disease.

Mandana Hunter et al.

Journal of neurochemistry, 146(5), 613-630 (2018-05-29)

The human subventricular zone (SVZ) has a defined cytological and neurochemical architecture, with four constituent laminae that act in concert to support its neurogenic activity. Lipidomic specialisation has previously been demonstrated in the neurologically normal human SVZ, with enrichment of
