Respiratory infections caused by nontuberculous mycobacteria (NTM), especially Mycobacterium avium, can lead to progressive, recurrent disease that is refractory to therapy. Bacterial biofilms are intrinsically resistant to a variety of stressors and pressures, including host killing mechanisms and antibiotic therapy. Though it is becoming increasingly evident that NTM biofilms are...
Giant reed (Arundo donax L.) is a candidate to provide feedstock for the Portland General Electric power plant in Boardman, Oregon. Giant reed is a fast perennial grass, producing 23-27 metric tons ha⁻¹ of biomass and has the ability to adapt to diverse environments making it a good candidate for...
Research in warm-climate biomes has shown that invasion by symbiotic dinitrogen (N₂)-fixing plants can transform ecosystems in ways analogous to the transformations observed as a consequence of anthropogenic, atmospheric nitrogen (N) deposition: declines in biodiversity, soil acidification, and alterations to carbon and nutrient cycling, including increased N losses through nitrate...
Introduction: Potential public health impacts of recreational cannabis legalization (RCL) are a growing concern, particularly for young adults. Some evidence suggests that following RCL, cannabis use increased, whereas alcohol use decreased among young adults. Co-use patterns have not been found to change following RCL in this age group. However, RCLs...
Rubus seed characteristics; seed coat morphology, anatomy, germination requirements and dormancy were studied in order to define protocols for breaking seed dormancy. Morphological analysis of the seed coat (testa) using scanning electron microscopy (SEM) included 56 seed accessions of 10 subgenera preserved in the collections of the US Department of...
Through examination of empirical evidence on individuals with Asperger’s Syndrome and related Pervasive Developmental Disorders, the author attempts to provide an overview of the social deficiencies associated with these disorders. Points of primary concern are the social deficiencies in developing competence in experience-sharing and demonstrating empathy, especially in how they...
