Prothrombin time testing practices: adherence to guidelines and standards.

Coagulation laboratory tests are vital to the diagnosis, treatment, and management of bleeding and hypercoagulability disorders. Some laboratories, however, fail to follow voluntary practice guidelines for coagulation testing (1, 2), and inappropriate performance of coagulation tests, such as the prothrombin time (PT) test, may contribute to coagulation and bleeding complications (3, 4).

Improving Management Practices for Invasive Cordgrass in the Pacific Northwest: A Case Study of Spartina anglica

Invasive species can radically alter the landscape and crowd out native plants and animals — a problem that costs the United States more than $100 billion each year. Washington state wrestles with dozens of aquatic invasive species including several cordgrasses in the genus Spartina. S. alterniflora was introduced into Willapa Bay about 100 years ago and has colonized over 6000 hectares of prev...

Pacific Northwest Fungi

Epiphytic macrolichen communities were compared among forest stand types in the Blue River watershed of western Oregon. Stand types were defined by stand structure, according to age classes of the younger tree cohort and remnant tree retention. Remnant trees were those in an older cohort that remained following a stand disturbance that initiated tree regeneration, such as a timber harvest or na...
