Rapid quantitation of free fatty acids in human plasma by high-performance liquid chromatography.

A Mehta et al.

Journal of chromatography. B, Biomedical sciences and applications, 719(1-2), 9-23 (1998-12-30)

We report a rapid and sensitive method for separation and quantitation of free fatty acids (FFAs) in human plasma using high-performance liquid chromatography (HPLC). Two established techniques of lipid extraction were investigated and modified to achieve maximal FFA recovery in

Derivatization and liquid chromatography-UV-tandem mass spectrometric analysis of perfluorinated carboxylic acids.

Jinxue Qiu et al.

Journal of chromatography. A, 1235, 132-140 (2012-03-10)

The presence of perfluorocarboxylates (PFCAs) in the environment is of increasing concern due to their possible toxicity to humans and bioaccumulation in organisms. PFCAs are frequently found in river water, sediment and organisms and sometimes even in groundwater. In order

Bothrops moojeni myotoxin-II, a Lys49-phospholipase A2 homologue: an example of function versatility of snake venom proteins.

Rodrigo G Stábeli et al.

Comparative biochemistry and physiology. Toxicology & pharmacology : CBP, 142(3-4), 371-381 (2006-01-31)

MjTX-II, a myotoxic phospholipase A(2) (PLA(2)) homologue from Bothrops moojeni venom, was functionally and structurally characterized. The MjTX-II characterization included: (i) functional characterization (antitumoral, antimicrobial and antiparasitic effects); (ii) effects of structural modifications by 4-bromophenacyl bromide (BPB), cyanogen bromide (CNBr)

Crystal structure of a phospholipase A(2) homolog complexed with p-bromophenacyl bromide reveals important structural changes associated with the inhibition of myotoxic activity.

Daniela P Marchi-Salvador et al.

Biochimica et biophysica acta, 1794(11), 1583-1590 (2009-07-21)

For the first time, the structure of a catalytic inactive phospholipase A(2) homolog (Lys49-PLA(2)s) complexed with p-bromophenacyl bromide (BPB) has been solved by X-ray crystallography. Lys49-PLA(2)s are among the main components of Viperidae snake venoms, causing myonecrosis and other actions

A secretory PLA2 associated with tobacco hornworm hemocyte membrane preparations acts in cellular immune reactions.

Youngjin Park et al.

Archives of insect biochemistry and physiology, 60(3), 105-115 (2005-10-20)

We report on a secretory phospholipase A2 (sPLA2) associated with membrane-enriched fractions prepared from hemocytes of the tobacco hornworms, Manduca sexta. Virtually no PLA2 activity was detected in serum of immunologically naive or bacterially challenged hornworms. PLA2 activity was detected
