South America's vast pantanal wetland may become next everglades, UNU experts warn
...nal commodities ?mainly cattle and fishing ?cannot compete in today's marketplace," says UNU-PREP Director Dr. Teixeira. "Traditional farmers are selling their land to outsiders and large scale agriculture is taking place in the high-lands surrounding the Pantanal.

...LPS binding. Most, if not all, of the CD14 ligands compete with LPS for CD14 binding. Therefore, they probably share the same binding pocket with LPS." Ligands other than LPS can be accommodated in the pocket due to its large size, the flexibility of its rim, and the multiple grooves available for ligand bi...Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows
