Even Flow, Marianne Koleng Dec 2025

Even Flow, Marianne Koleng

be Still

This piece attempts to connect the "ebb and flow" of music and art with the sometimes strict interpretation of anatomy. It calls to attention what often seem as opposites - the cold nature of medicine and science with the seemingly warm and free nature of music and art. While many see them as opposites, this piece attempts to convey they are really two sides of the same coin.

Investigating The Origins Of Symbiosis Using A Novel Mycorrhizal Interaction In Pasque Flowers (Pulsatilla Patens), Savannah Lane Draud Dec 2025

Investigating The Origins Of Symbiosis Using A Novel Mycorrhizal Interaction In Pasque Flowers (Pulsatilla Patens), Savannah Lane Draud

Electronic Theses and Dissertations

Mycorrhizal fungi form mutualistic symbioses with most land plants, occurring primarily as arbuscular mycorrhizal (AM) fungi or ectomycorrhizal (ECM) fungi. Pulsatilla patens, an herbaceous perennial widely distributed across Eurasia and North America, belongs to a plant family historically known only to form AM associations. However, recent discoveries of ECM P. patens individuals in northeastern Poland raise questions about the mycorrhizal status and evolutionary trajectory of this species. Because ECM formation in this lineage is likely evolutionarily recent, P. patens offers a valuable system for investigating the ecological and historical factors that facilitate the emergence of ECM symbiosis.

Decomposition Processes And Insect Indicators In Forensic Investigations, Eli Taylor Dec 2025

Decomposition Processes And Insect Indicators In Forensic Investigations, Eli Taylor

University Honors Theses

Insects play an essential biological and ecological role in human life, and their predictable relationship with decomposing remains has positioned them as a cornerstone of modern forensic science. Since the early 20th century, forensic entomology has provided critical evidence for estimating the postmortem interval (PMI), relying on patterns of colonization, species succession, and insect developmental timelines. Accurate PMI estimations are vital to medicolegal investigations, influencing the interpretation of biological evidence, guiding resource allocation, and informing determinations of cause and manner of death. However, insect activity is profoundly shaped by environmental and ecological variables, including temperature, humidity, seasonal shifts, and geographic …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Primary sarcopenia is an age-associated disorder with progressive and generalised loss of skeletal muscle strength and mass. Skeletal muscle fibrosis is one of the significant pathological manifestations of age-associated sarcopenia. Decorin, a small dermatan-sulfate proteoglycan, participates in extracellular matrix assembly. In numerous studies, the involvement of decorin is not restricted to matrix structural proteins, and it also affects a diverse variety of biological functions like cell growth, adhesion, migration, proliferation and differentiation. Additionally, it modulates the process of inflammation and fibrillogenesis. Based on these preclinical evidences, we hypothesised that decorin may potentially play an important role in skeletal muscles …
