Racial disparities in ALS diagnostic delay: a single center's experience and review of potential contributing factors.

Objective: Outcomes for amyotrophic lateral sclerosis (ALS) patients are improved with prompt diagnosis, earlier initiation of disease-modifying treatments, and participation in a multidisciplinary clinic. We studied diagnostic delay and disease severity at time of clinic presentation between Black and non-Hispanic Caucasian ALS patients.

Methods: We performed a retrospective analysis of non-Hispanic Caucasian and Black ALS patients seen in the Virginia Commonwealth University Health System multidisciplinary ALS clinic between 2017 and 2023.

Inhibitors of unactivated p38 MAP kinase.

Inhibition of the p38 map kinase pathway has been shown to be beneficial in the treatment of inflammatory diseases. The first class of potent p38 kinase inhibitors was the pyridinylimidazole compounds from SKB. Since then several pyridinylimidazole-based compounds have been shown to inhibit activated p38 kinase in vitro and in vivo.

Structure-activity relationships of triazolopyridine oxazole p38 inhibitors: identification of candidates for clinical development.

The synthesis, structure-activity relationship, in vivo activity, and metabolic profile for a series of triazolopyridine-oxazole based p38 inhibitors are described. The deficiencies of the lead structure in the series, CP-808844, were overcome by changes to the C4 aryl group and the triazole side-chain culminating in the identification of several potential clinical candidates.

Drug-eluting stents: sirolimus and paclitaxel differentially affect cultured cells and injured arteries.

Sirolimus and paclitaxel eluted from stents inhibit cell proliferation and other cellular processes by dramatically different mechanisms. In this study, the effects of sirolimus and paclitaxel on cultured human coronary artery smooth muscle and endothelial cell function or cell cycle changes in balloon-injured arteries were directly compared. Both sirolimus and paclitaxel inhibited smooth muscle and endothelial cell proliferation.

Impaired inflammatory and pain responses in mice lacking an inducible prostaglandin E synthase.

Prostaglandin (PG)E2 is a potent mediator of pain and inflammation, and high levels of this lipid mediator are observed in numerous disease states. The inhibition of PGE2 production to control pain and to treat diseases such as rheumatoid arthritis to date has depended on nonsteroidal antiinflammatory agents such as aspirin. However, these agents inhibit the synthesis of all prostanoids.
