Meat, The Future: The Role Of Regulators In The Lab-Grown Revolution, Joseph B. Davault, Michael S. Sinha

All Faculty Scholarship

The United States is one of the largest consumers of meat globally. The production of meat contributes substantially to climate change due to the levels of greenhouse gasses emitted and the amount of land, water, feed, and other natural resources required to raise animals used for meat. Traditional meat production is another major source for the emergence of zoonotic diseases and antimicrobial-resistant pathogens. Nevertheless, Americans consume more meat now than at any time in the nation’s history.

Advocates for policy change aimed at addressing the risks associated with meat production have typically focused on reducing meat consumption, alternatives to meat, …

Transcription Factor Expression Landscape In Drosophila Embryonic Cell Lines, Robert A. Drewell, Daniel Klonaros, Jacqueline Dresch

Biology

Background: Transcription factor (TF) proteins are a key component of the gene regulatory networks that control cellular fates and function. TFs bind DNA regulatory elements in a sequence-specific manner and modulate target gene expression through combinatorial interactions with each other, cofactors, and chromatin-modifying proteins. Large-scale studies over the last two decades have helped shed light on the complex network of TFs that regulate development in Drosophila melanogaster. Results: Here, we present a detailed characterization of expression of all known and predicted Drosophila TFs in two well-established embryonic cell lines, Kc167 and S2 cells. Using deep coverage RNA sequencing approaches we …

Providing Proteins To Belizean Residents Through Poultry Products, Ellis Freel

Poultry Science Undergraduate Honors Theses

Belize is a food insecure, developing country. Although Belize has plenty of nutritious food in-country, the exportation of that food to generate income contributed to a distribution issue of that nutritious food. More impoverished areas of Belize do not have access to nutritious food because of the lack of affordability and high export rates. Diets with a lack of food, or lack of balanced, nutritious food can negatively impact growth and cognitive development, especially in children. Poultry is one of the only products in Belize not able to be exported. Implementing poultry into Belizean diets would affordably alleviate food insecurity …

Effects Of Roadways On Seasonal Movement Strategies And Mate Location Success In An Imperiled Pit Viper (Crotalus Horridus), Elizabeth J. Noble

Graduate Research Showcase

A detailed understanding of animal movement behavior is fundamental to effective conservation and management. Within populations, a diversity of movement strategies can be displayed in search of critical resources, and these strategies are influenced by multiple interacting factors related to individuals and the environment. Mating partners are one critical resource that often serves as a prominent selective force shaping movement during mating seasons. For many large-bodied snakes, such as pit vipers (Viperidae: Crotalinae), male mate- searching movements are the primary determinant of mate location success. During this time, males incur significant risks associated with elevated movement. In an increasingly human- …

The Reveal: A Technical Study And Conservation Treatment Of An Overpaint Portrait, Camille Ferrer

Art Conservation Master's Projects

A severely damaged 19th-century oil painting depicting a portrait of a woman was treated at Patricia H. and E. Garman Art Conservation Department. A typed letter provided by the owner mentioned that it has been previously restored yet returned with unsatisfactory results. After further examination, the painting appeared to have been previously treated multiple times by different people. There was overpaint distinctly present on the face and later discovered to be present overall. The full state of condition of the painting was initially unknown due to the sum of the surface being overpainted. However, there were evidence of paint loss …

Aerobic Exercise Improves Depressive Symptoms In The Unilateral 6-Ohda-Lesioned Rat Model Of Parkinson's Disease, Hannah Loughlin, Jacob Jackson, Chloe Looman, Alayna Starll, Jeremy Goldman, Zhiying Shan, Chunxiu Yu

Michigan Tech Publications, Part 2

Aerobic exercise has been shown to have established benefits on motor function in Parkinson's disease (PD). However, the impact of exercise on depressive symptoms in PD remains unclear. This study aimed to investigate the effects of regular exercise, specifically using a forced running wheel, on both motor performance and the prevalence of depression in a unilateral 6-OHDA-lesioned rat model of PD. The behavioral outcomes of exercise were assessed through the rotarod test (RT), forelimb adjusting step test (FAST), sucrose consumption test (SCT), and novelty sucrose splash test (NSST). Our data revealed evident depressive symptoms in the PD animals, characterized by …

On-Site Sensory Experience Boosts Acceptance Of Cultivated Chicken, Mark Chong, Angela K. Y. Leung, Tricia Marjorie Fernandez

Research Collection Lee Kong Chian School Of Business

This study set out to assess if presenting cultivated chicken in the context of a familiar meal, in a familiar dining setting, would motivate repeat consumption and recommendation. A survey of 107 diners was conducted at Huber's Butchery and Bistro in Singapore – the world's first butchery to serve cultivated meat – from April to June 2023. The findings showed that eating cultivated chicken significantly boosted post-consumption acceptance levels. In addition, cultivated chicken's tastiness may be a more important factor than its integration into a familiar meal or dish in fostering repeat consumption. Implications for the cultivated meat industry, limitations, …

Oil Identification Of Harp Seal And Other Select Marine Mammals, Meghan Pinedo, Deborah A. Duffield, Dalin N. D’Alessandro, Erin R. Price, Edgard O. Espinoza

Biology Faculty Publications and Presentations

Because of the rich omega-3 fatty acids content, harp seal (Pagophilus groenlandicus) oil is a popular supplement that is packaged as pills in Canada and sold for medicinal purposes, although this practice is banned in the United States. Due to US regulations, it is important to be able to distinguish between fish oil and seal oil, but the taxonomic determination of oils provenance has been a difficult problem to solve. In this study, Direct Analysis in Real Time time-of-flight mass spectrometry (DART TOFMS) was used to analyze the chemotypes of blubber samples collected from seven species of …

Positron Emission Tomography In Oncology And Environmental Science, Samantha Delaney

Dissertations, Theses, and Capstone Projects

The last half century has played witness to the onset of molecular imaging for the clinical assessment of physiological targets. While several medical imaging modalities allow for the visualization of the functional and anatomical properties of humans and living systems, few offer accurate quantitation and the ability to detect biochemical processes with low-administered drug mass doses. This limits how physicians and scientists may diagnose and treat medical issues, such as cancer, disease, and foreign agents.

A promising alternative to extant invasive procedures and suboptimal imaging modalities to assess the nature of a biological environment is the use of positron emission …
