Cell Rep. 2015 Mar 10;10(9):1626-1638. doi: 10.1016/j.celrep.2015.02.012. Epub 2015 Mar 05.

Inflammatory response induced by microglia plays a critical role in the demise of neuronal populations in neuroinflammatory diseases. Although the role of toll-like receptor 4 (TLR4) in microglia's inflammatory response is fully acknowledged, little is known about endogenous ligands...

Arctic cyclone water vapor isotopes support past sea ice retreat recorded in Greenland ice.

Scientific reports

Klein ES, Cherry JE, Young J, Noone D, Leffler AJ, Welker JM.
PMID: 26023728
Sci Rep. 2015 May 29;5:10295. doi: 10.1038/srep10295.

Rapid Arctic warming is associated with important water cycle changes: sea ice loss, increasing atmospheric humidity, permafrost thaw, and water-induced ecosystem changes. Understanding these complex modern processes is critical to interpreting past hydrologic changes preserved in paleoclimate records and...

PMID: 28307753
Oecologia. 1999 May;119(3):311-319. doi: 10.1007/s004420050791.

Water availability is an important factor limiting the productivity of desert plants but little is known about the impact of water-limiting conditions on the physiology of plants in mesic environments. Riparian ecosystems of the western US receive significantly more...

Predictive value of epigenetic alterations in head and neck squamous cell carcinoma.

Molecular & cellular oncology
