Macrophage Infiltration And Activation In Old And Young Skeletal Muscle Following Lengthening Contractions, Jamie P. Kaluhiokalani, Jacob R. Sorensen, Robert D. Hyldahl

Library/Life Sciences Undergraduate Poster Competition 2019

•Human skeletal muscle is capable of robust regeneration following damage. •Muscle repair following injury is dependent on the timely activity of pro-inflammatory (M1) and anti-inflammatory, pro-regenerative (M2) macrophages. Following acute muscle injury, healthy skeletal muscle experiences a rapid and vigorous inflammatory response. •Macrophages clear necrotic tissue and facilitate satellite cell behavior through the secretion of cytokines and growth factors. •It is known that aged muscle experiences poor regenerative potential following injury, but the cause is not well-understood.

Purpose: The purpose of this study was to investigate macrophage behavior in old and young people in the context of muscle damage.

Effectiveness Of The Smallholder Sustainability Assessment Of Food And Agricultural Systems App For Subsistence Farm Systems In Ecuador, Carter D. Allred, H. L. Boman, S. J. Clawson, C. A. Freestone, S. N. Hockett, C. A. Holden, E. R. Phipps, C. N. Quigley, M. M. Rupard, N. C. Hansen

Small-scale agriculture is the primary source of food for the majority of the developing world. It is a vital component of the total global land usage for agricultural production, and sustaining and improving subsistence farms is critical for meeting global food demand as well as maintaining the integrity of agro-ecological systems. Due to the important role that smallholder farmers play in global agriculture, the Food and Agriculture Organization of the UN developed the Smallholder Sustainability Assessment of Food and Agricultural Systems App (SAFA), a 100-question survey tool created for simplicity and wide-reaching applicability. SAFA is flexible in nature in that …

Discovery Of Geographical Gene Variants In Related Pseudomonas Aeruginosa Bacteriophages, Emilee Carr, Elise Melhado, Emily Loertscher, Trever Thurgood, Ruchira Sharma, Julianne H. Grose

Antibiotic resistant bacterial strains are a major crisis in the world due to the difficult nature of curing individuals afflicted with them. Phage therapy has been proposed as an alternate treatment for these bacterium. In Dr. Julianne Grose's lab, bacteriophages were against the bacteria, Pseudomonas aeruginosa. To isolate, environmental samples were utilized in enrichment cultures that were ultimately used in serial dilutions, plaque purification, electron microscopy, DNA isolation, sequencing, and genome annotation. The P. aeruginosa phage, TF17, infects a bacterial strain that is highly related to a strain that causes fatalities as an opportunistic infection in patients with cystic fibrosis. …
