Studies suggest promising new directions for gallstone treatment
...removed because of gallstones. In this disorder, a sludge
of cholesterol-supersaturated bile inflames the bile duct because of its abnormal properties. By restoring the normal properties of bile, the drug would render it less viscous and inflammatory. While the drug used in the experiments is an expensive e...
Gene sequencing explains bioremediation 'bug'
... (a chlorinated solvent used for dry cleaning), in sludge
