This research investigated the effects of Pediococcus spp. on Oregon Pinot noir wines. Pediococcus (P. parvulus (7), P. damnosus (1), P. inopinatus (1)) isolated from Oregon and Washington state wines demonstrated differences in their susceptibility to SO₂ with some isolates growing well in model media at 0.4 mg/L molecular SO₂....
This study aimed to explore the relationship between grassroots activism, in the form of a plastic bag ban, and social capital. I postulated that grassroots activism would lead to higher levels of social capital. The data was collected through a survey distributed on community bulletin boards, an announcement at a...
The operation of the Federal Columbia River Power System (FCRPS) has negatively affected threatened and endangered salmonid populations in the Pacific Northwest. Barging Snake River spring Chinook salmon Oncorhynchus tshawytscha through the FCRPS is one effort to mitigate the effect of the hydrosystem on juvenile salmon out-migration. However, little is...
Osteochondrosis (OC) is a developmental orthopedic disease that results from a disruption to normal endochondral ossification in the articular-epiphyseal growth complex. In mammals, the hedgehog pathway and growth factor signaling are essential to this process. Previous studies in yearling horses with OC have shown upregulation of Indian hedgehog and insulin-like...
Objective- To determine the average flexion and standing extension measurements for each limb articulation of alpacas and llamas and determine if there was any significant difference between the species’ measurements. Animals- Alpacas (n=6) and llamas (n=6) of the Oregon State University teaching herd. Methods- Each articulation was measured four times...
Suspensory apparatus breakdown and hyperextension of the metacarpophalangeal and metatarsophalangeal (fetlock) joints is a common condition in the llama and has been observed in llamas of all ages. Llama breeders refer to the condition as "down in the pasterns" or "down in the fetlocks." The condition can result in debilitating...
Osteochondrosis (OC) is a major source of lameness in horses, involving abnormal maturation of cartilage during the first year of life. Previous studies have shown that cartilage canals may be associated with early OC lesions with accumulation of large numbers of small rounded chondrocytes surrounding the canals. Altered expression of...
Osteochondrosis (OC) results from disruption of the normal endochondral ossification process during articular cartilage and epiphyseal bone growth. Previous studies have revealed that cartilage canals are often associated with early OC lesions, especially along the ossification front. In early OC, extracellular matrix signaling pathways are expected to be altered, as...
The objective of this study was to elucidate the expression of signaling molecules associated with the Wnt signaling pathway in cartilage of prepubescent foals and determine their association with chondrocytes located at the osteochondral junction and cartilage canals. Our hypothesis was that increased expression of the components of the Wnt...
