... Mitochondrial aldehyde dehydrogenase (ALDH2) is the major ALDH isozyme involved in acetaldehyde metabolism. It is well established that a single nucleotide substitution (G to A) leads to the amino acid change (Glu487Lys) and dominant inactivation of ALDH2 activity. Inactivation of ALDH2 activity causes the aversive reactions associated with “flushing” response observed in many East Asian people fo ...

Abstract:
... The accuracy of a northeastern California vegetation map was assessed using the data from a grid of permanent Forest Inventory and Analysis (FIA) plots collected by Region 5 and the Pacific Northwest Research Station (PNW). The map was assessed in three parts: the Modoc National Forest, the Lassen National Forest and the lands outside National Forest boundaries. Accuracy was assessed hierarchicall ...

Abstract:
... With the move to intensive forest management to meet wood demand and to preserve the environment, southeast Alaska is experiencing a period of significant change in terms of wood characteristics or wood quality. In order to responsibly manage the young-growth stands, it is important to evaluate tree quality prior to harvest and understand the product and economic potential of the wood fiber in sta ...

Abstract:
... Increased emphasis on reduction of mercury emissions from coal fired electric power plants have resulted in environmental regulations that may in the future require application of activated carbons as mercury sorbents. The sorbents could be injected into the flue gas stream where it adsorbs the mercury. The sorbent (now containing mercury) would be removed via filtration or other means from the fl ...
