Backpacking in Yosemite and Kings Canyon National Parks and neighboring wilderness areas: how safe is the water to drink?
Alpine wilderness water below cattle areas used by pack animals is at risk for containing coliform organisms. Water from wild, day hike, or backpack areas showed far less risk for coliforms.
The results suggest that in PBC, FasL expressing CD68+ monocytes are at least partly involved in apoptotic bile duct loss mediated by the Fas system, and a surface molecule, CD14, participates in this process.
