Diclofenac toxicity in human intestine ex vivo is not related to the formation of intestinal metabolites.

Arch. Toxicol. 89(1) , 107-19, (2015)

The use of diclofenac (DCF), a nonsteroidal anti-inflammatory drug, is associated with a high prevalence of gastrointestinal side effects. In vivo studies in rodents suggested that reactive metabolite...

cIEF for rapid pKa determination of small molecules: a proof of concept.

Eur. J. Pharm. Sci. 63 , 14-21, (2014)

A capillary isoelectric focusing (cIEF) method was developed for the determination of the ionization constants (pKa) of small molecules. Two approaches used to decrease the electroosmotic flow (EOF) w...

Involvement of the H1 Histamine Receptor, p38 MAP Kinase, Myosin Light Chains Kinase, and Rho/ROCK in Histamine-Induced Endothelial Barrier Dysfunction.

Microcirculation 22 , 237-48, (2015)

The mechanisms by which histamine increases microvascular permeability remain poorly understood. We tested the hypothesis that H1 receptor activation disrupts the endothelial barrier and investigated ...
