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 …

Interventions For Online Gambling Addiction With Vulnerable Populations, Ethan Sarin

University Honors Theses

This paper looks at the modern rise of online gambling, what has been done to address it, and how we can improve upon them in the future. Online gambling is gambling done through a digital medium with two distinct forms: gambling adjacent activities (GAAs), and general online gambling. GAAs are activities that highly resemble gambling, but are legally distinct from gambling due to different kinds of obfuscation like using in-game currency to gamble instead of directly real world money. General online gambling is much clearer about it being gambling with many kinds of gambling activities to partake in from digital …

Decorin Deficiency Promotes D-Galactose-Induced Skeletal Muscle Atrophy And Fibrosis By Regulating Itgb1/Akt/Mtor Signalling Pathway, Xiaoqin Luo, Mengxue Zhang, Lili Chen, Ruichang Wang, Jiabing Lian, Zhe Yang, Renato V. Iozzo, Jin Wang, Yan Zhang, Xiuli Bi

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 …
