Effects of Galactooligosaccharides on the Gut Microbiota in Lactose Intolerant Individuals

Creator:: Angima, Gloria
Abstract:: Lactose intolerance is a common food intolerance that occurs because of a post-weaning deficiency of lactase, an enzyme that cleaves the glyosidic bond of lactose. About 75% of the world's population is lactose intolerant. Common symptoms of lactose intolerance are abdominal pain, bloating and diarrhea. ~25% of the world’s population...

Tree Species Selection Across Municipalities in the Pacific Northwest

Creator:: Petter, Joshua S.
Abstract:: There are many benefits provided by trees in urban areas. While there are many recommendations on maximizing the returns from urban trees, there has been little research examining how these managers are prioritizing their tree species selection. A survey instrument was constructed to survey Tree City USA designated cities across...

Impacts of Stocking Density on Development and Puberty Attainment of Replacement Beef Heifers

Creator:: Schubach, Kelsey M.
Abstract:: The following experiment presented herein compared growth, physical activity, stress-related responses, and puberty attainment in heifers reared on high- (HIDENS) or low-stocking densities (LOWDENS). Sixty Angus x Hereford heifers were ranked by age and BW (210 ± 2 d and 220 ± 2 kg, respectively) on d 0, and assigned...

The Role of Tumor-Derived Exosomes in the Development of Carboplatin Resistance in Canine Osteosarcoma

Creator:: Weinman, Marcus
Abstract:: Many humans and canines alike suffer from osteosarcoma, which is often metastatic, resistant to chemotherapy, and frequently fatal. The mechanisms through which osteosarcoma cells acquire resistance to chemotherapy are not entirely understood, and the role of exosomes as intercellular mediators of this resistance in osteosarcoma is unknown. Using established canine...

Of Mysid and Menidia: Sublethal Effects of Micro and Nanoplastics on Estuarine Indicator Species

Creator:: Dickens, John
Abstract:: Microplastics are widely distributed in aquatic environments. The term ‘microplastics’ encompasses a wide array of particles with unique polymer constituents, morphologies, and sources, such as automobile tire tread. Tire wear particles (TWP) can end up in waterways near densely populated municipalities, where they can interact with aquatic biota. Studying the...

On the Role of Spatial Clustering Algorithms in Building Species Distribution Models from Community Science Data

Creator:: Roth, Mark
Abstract:: This paper discusses opportunities for developments in spatial clustering methods to help leverage broad scale community science data for building species distribution models (SDMs). SDMs are critical tools that inform the science and policy needed to mitigate the impacts of climate change on biodiversity. Community science data span spatial and...

Indoor Localization Using Direction of Arrival Approach

Creator:: Zhang, Tingwei
Abstract:: In this paper, a Direction of Arrival (DOA) based system is proposed. This method searches the direction relative to the array to find where the signal source is located. The proposed system can achieve sub-meter level accuracy with a near real-time update rate. Also, we introduced several refinement methods including...

Development and applications of a high-throughput activity assay, using the ammonia-oxidizing bacteria Nitrosomonas europaea

Creator:: Bartow, Shannon M.
Abstract:: The rising demand on freshwater resources emphasizes the benefit of biogeochemical processes that maintain clean water by removing pollutants such as excess nitrogen. The most sensitive step in the removal of nitrogen from waterways is the oxidation of ammonia, a part of nitrification, which is carried out by ammonia oxidizing...

Leveraging multi-sensor time series datasets to map short- and long-term forest disturbances and drivers of change in the Colombian Andes

Creator:: Murillo Sandoval, Paulo Jose
Abstract:: The spatial distribution of forest disturbance is commonly calculated using a satellite imagery-driven bi- or tri-temporal change analysis. Working in Colombia’s Cordillera de los Picachos National Natural Park – a region of consistent cloud cover and dramatic topographic relief – a change assessment with such infrequent observations cannot capture long-term...

Anti-inflammatory and Antioxidant Potential of Alaska Pollock Milt and Roe Hydrolysates

Creator:: Kemp, David C.
Abstract:: Ample research has demonstrated the largely untapped potential of bioactive peptides (BAPs) for treating systematic chronic inflammation (SCI). Protein hydrolysates are the mixture of peptides resulting from the hydrolytic breakdown of a protein. Numerous hydrolysates contain BAPs and exert beneficial effects in both in vitro and in vivo models. In...
