PROFITABILITY ANALYSIS OF SOYBEAN APHID CONTROL TREATMENTS IN THREE NORTH-CENTRAL STATES
Crop Production/Industries,
Geographic Distribution of Soybean Aphid Biotypes in the United States and Canada during 2008–2010
Soybean aphid (Aphis glycines Matsumura) is a native pest of soybean [Glycine max (L.) Merr.] in eastern Asia and was detected on soybeans in North America in 2000. In 2004, the soybean cultivar Dowling was described to be resistant to soybean aphids with the Rag1 gene for resistance. In 2006, a virulent biotype of soybean aphid in Ohio was reported to proliferate on soybeans with the Rag1 gene. The objective was to survey the occurrence of virulent aphid populations on soybean indicator lines across geographies and years. Nine soybean lines were identified on the basis of their degree of aphid resistance and their importance in breeding programs. Naturally occurring soybean aphid populations were collected in 10 states (Kansas, Illinois, Indiana, Iowa, Michigan, Minnesota, North Dakota, Ohio, South Dakota, and Wisconsin) and the Canadian province of Ontario. The reproductive capacity of field-collected soybean aphid populations was tested on soybean lines; growth rates were compared in no-choice field cages at each geographic region across 3 yr. The occurrence of soybean aphid biotypes was highly variable from year to year and across environments. The frequency of Biotypes 2, 3, and 4 was 54, 18, and 7%, respectively, from the 28 soybean aphid populations collected across 3 yr and 11 environments. Plant introduction (PI) 567598B, a natural gene pyramid of rag1c and rag4, had lowest frequency of soybean aphid colonization (18%). Several factors may have contributed to the variability, including genetic diversity of soybean aphids, parthenogenicity, abundance of the overwintering host buckthorn (Rhamnus spp.), and migratory patterns of soybean aphids across the landscape

The Oregon Tribal Archives Institute: Providing a Professional Development and Networking Opportunity for Oregon’s Tribal Communities
Presentation about the Oregon Tribal Archives Institute given at the 2013 Joint Conference of the Northwest Archivists (NWA) and the Archives Association of British Columbia (AABC) in Vancouver, B.C.In August of 2012, the Oregon State University Libraries, with assistance from various partners, hosted the Oregon Tribal Archives Institute (TAI), the culmination of a two year grant project made possible by an Oregon State Library (LSTA) Library Services & Technology Act grant. The week long Institute was designed to address the need for in-depth archives and records management training for Oregon’s nine federally recognized tribes to support and facilitate the preservation of the cultural sovereignty of tribal nations through their archival collections and records. Representatives of all of Oregon’s nine tribes attended the Institute. This project is a potential model for other institutions to connect, collaborate, and reach out to their local tribal communities to assist in their professional development and archival education. This panel presentation will focus on development of the grant, the site visits to all nine tribes to conduct needs assessments, the Institute planning and curriculum development, the Institute itself, and the outcomes of the project.

One Year of Alendronate Treatment Lowers Microstructural Stresses Associated with Trabecular Microdamage Initiation
Alendronate, an anti-remodeling agent, is commonly used to treat patients suffering from osteoporosis by increasing bone mineral density. Though fracture risk is lowered, an increase in microdamage accumulation has been documented in patients receiving alendronate, leading to questions about the potentially detrimental effects of remodeling suppression on the local tissue (material) properties. In this study, trabecular bone cores from the distal femur of beagle dogs treated for one year with alendronate, at doses scaled by weight to approximate osteoporotic and Paget's disease treatment doses in humans, were subjected to uniaxial compression to induce microdamage. Tissue level von Mises stresses were computed for alendronate-treated and non-treated controls using finite element analysis and correlated to microdamage morphology. Using a modified version of the Moore and Gibson classification for damage morphology, we determined that the von Mises stress for trabeculae exhibiting severe and linear microcrack patterns was decreased by approximately 25% in samples treated with alendronate compared with non-treated controls (p<0.01), whereas there was no reduction in the von Mises stress state for diffuse microdamage formation. Furthermore, an examination of the architectural and structural characteristics of damaged trabeculae demonstrated that severely damaged trabeculae were thinner, more aligned with the loading axis, and less mineralized than undamaged trabeculae in alendronate-treated samples (p<0.01). Similar relationships with damage morphology were found only with trabecular orientation in vehicle-treated control dogs. These results indicate that changes in bone's architecture and matrix properties associated with one year of alendronate administration reduce trabecular bone's ability to resist the formation of loading-induced severe and linear microcracks, both of which dissipate less energy prior to fracture than does diffuse damage
Analysis of the MOST light curve of the heavily spotted K2IV component of the single-line spectroscopic binary II Pegasi
Continuous photometric observations of the visible component of the
single-line, K2IV spectroscopic binary II Peg carried out by the MOST satellite
during 31 consecutive days in 2008 have been analyzed. On top of spot-induced
brightness modulation, eleven flares were detected of three distinct types
characterized by different values of rise, decay and duration times. The flares
showed a preference for occurrence at rotation phases when the most spotted
hemisphere is directed to the observer, confirming previous similar reports. An
attempt to detect a grazing primary minimum caused by the secondary component
transiting in front of the visible star gave a negative result. The brightness
variability caused by spots has been interpreted within a cold spot model. An
assumption of differential rotation of the primary component gave a better fit
to the light curve than a solid-body rotation model.Comment: Accepteed to MNRA
Severe combined hyperlipidaemia and retinal lipid infiltration in a patient with Type 2 diabetes mellitus
Severe combined hyperlipidaemia has occasionally been associated with infiltration of tissues in addition to arteries and the skin. We report a woman with Type 2 diabetes mellitus (DM) and severe combined hyperlipidaemia who developed retinal lipid infiltration, resulting in blindness. A 61-year-old woman with a 15-year history of Type 2 DM was admitted following a two-week history of progressive visual loss. Examination identified lipid infiltration into the retina. Phenotypically she had severe combined hyperlipidaemia with elevated IDL cholesterol and a broad beta band on lipoprotein electrophoresis, raising the possibility of familial dysbetalipoproteinaemia. However, gene sequencing analysis indicated that the patient was homozygous for the E3/E3 allele of the ApoE gene with no mutations detected in either the coding region or intron-exon boundaries. Her lipid profile improved following dietary therapy and gemfibrozil treatment, but this had little effect on either her fundal appearances or her visual acuity. Type 2 DM plays a vital role both in allowing expression of severe combined hyperlipoproteinaemia, in addition to serving as a risk factor for complications such as tissue infiltration
