Enhancement of ninhydrin- or DFO-treated latent fingerprints on thermal paper.

Lothar Schwarz et al.

Journal of forensic sciences, 52(3), 649-655 (2007-04-26)

A new method for enhancement of ninhydrin or 1,8-diazafluoren-9-one (DFO)-treated latent fingerprints on thermal paper will be described. Most thermosensitive surfaces of thermal paper become dark when treated with DFO or ninhydrin petroleum ether (NPB) solution. This effect minimizes contrast

Two-channel dansyl/tryptophan emitters with a cholic acid bridge as reporters for local hydrophobicity within supramolecular systems based on bile salts.

M Gomez-Mendoza et al.

Organic & biomolecular chemistry, 12(42), 8499-8504 (2014-09-19)

The aim of the present work is to develop two-channel emitters to probe local hydrophobicity by means of fluorescence quenching within different biomimetic supramolecular environments. To achieve this goal, the dansyl (Dns) and tryptophan (Trp) fluorophores have been covalently attached

Enantioselective addition of amines to ketenes catalyzed by a planar-chiral derivative of PPY: possible intervention of chiral Brønsted-acid catalysis.

Brian L Hodous et al.

Journal of the American Chemical Society, 124(34), 10006-10007 (2002-08-22)

The first method for the catalytic enantioselective addition of amines (specifically, pyrroles) to ketenes has been developed, and it has been demonstrated that the resulting acylpyrroles can be transformed into a broad spectrum of useful derivatives. On the basis of

Pyridine derivatives stimulate phosphatidylcholine secretion in primary cultures of rat type II pneumocytes.

H Kai et al.

The Journal of pharmacy and pharmacology, 48(1), 53-56 (1996-01-01)

We have examined the effects of pyridine derivatives on phosphatidylcholine secretion in primary cultures of rat type II pneumocytes. Of 12 pyridine derivatives, 4-aminopyridine, 4-dimethylaminopyridine and 4-pyrolidinopyridine had a stimulatory effect on phosphatidylcholine secretion, whereas other derivatives had little effect.

Biomarkers probed in saliva by surface plasmon resonance imaging coupled to matrix-assisted laser desorption/ionization mass spectrometry in array format.

Johana Musso et al.

Analytical and bioanalytical chemistry, 407(5), 1285-1294 (2014-12-20)

Detection of protein biomarkers is of major interest in proteomics. This work reports the analysis of protein biomarkers directly from a biological fluid, human saliva, by surface plasmon resonance imaging coupled to mass spectrometry (SPRi-MS), using a functionalized biochip in

Journal of Applied Polymer Science. Applied Polymer Symposium, 50, 149-149 (1993)

A method for the synthesis of isomerically pure saturated mixed-chain phosphatidylcholines.

J T Mason et al.

Analytical biochemistry, 113(1), 96-101 (1981-05-01)

Polymer, 34, 1297-1297 (1993)
