This study examines the impact of yeast selection on fermentation performance, filtration efficiency, and the stability of low-alcohol and non-alcoholic beer (NAB). Three yeast strains (LA-01, LoNa, and W-34/70) were evaluated for their effects on key NAB parameters like ABV, bitterness, color, haze readings, and filtration-linked performance. Filtration trials revealed that highly flocculating W-34/70 resulted in lower post-filtration turbidity, whereas LA-01 and LoNa (which flocculated less) required more effective filtration techniques to achieve clarity. Among the tested filter sheets, AF 31, AF 71, and AF 101 successfully reduced turbidity below 2 EBC. However, all NABs exhibited haze formation during storage, …

Cancer cachexia (CC) is marked by severe skeletal muscle loss and dysfunction, associated with mitochondrial degeneration. Our previous studies showed induction of the mitophagy marker BNIP3 3-wk post-Lewis lung carcinoma (LLC) induction. We hypothesize that excessive mitophagy contributes to muscle wasting in CC. To test this, we used a Bnip3 knockout (KO) mouse model with LLC-induced CC to assess its impact on muscle outcomes. Eight-wk-old male and female mice were injected with 1 x 10(6) LLC cells or PBS (sham controls). After 4 wk, we assessed muscle function through dorsiflexor electrophysiology, muscle protein synthesis via deuterium oxide labeling, and mitochondrial …

The nucleolus is a membraneless organelle and an excellent stress sensor. Any changes in its architecture or composition lead to nucleolar stress, resulting in cell cycle arrest and interruption of ribosomal activity, critical factors in aging and cancer. In this study, we identified and described the pivotal role of the RNA-binding protein HNRNPK in ribosome and nucleolar dynamics. We developed an in vitro model of endogenous HNRNPK overexpression and an in vivo mouse model of ubiquitous HNRNPK overexpression. These models showed disruptions in translation as the HNRNPK overexpression caused alterations in the nucleolar structure, resulting in p53-dependent nucleolar stress, cell …

Is Anoxia Tolerance A Common Trait In Fish Cell Lines?, Lori Tran

University Honors Theses

Most vertebrates need a constant supply of oxygen to sustain life, with disruption to O2 supply or delivery quickly leading to cell and tissue damage and death. Many aquatic species are able to withstand long periods without O2 due to evolving to survive the regular periods of hypoxia and anoxia in their natural habitat. The Austrofundulus limnaeus, or the annual killifish, in particular have shown the highest anoxia tolerance in all vertebrates and is a promising model for developing effective treatments for anoxia-related damage, such as heart attacks and strokes. The A. limnaeus are not the only …

A facile and low-energy-dependent extraction method was used that did not require the use of high-temperature annealing. The synthesized nanoparticles showed a maximum UV absorption at 347 nm, which corresponds to a 3.58 eV band gap energy. FTIR confirmed the successful …


Analysis Of Synaptotagmin Isoforms In Lßt2 Gonadotrophs, Caitlin Vahl Jun 2025

Analysis Of Synaptotagmin Isoforms In Lßt2 Gonadotrophs, Caitlin Vahl

Undergraduate Theses, Capstones, and Recitals

The anterior pituitary is comprised of five cell types which secrete regulatory hormones into the bloodstream. Specifically, gonadotrophs synthesize and release sex hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in response to gonadotropin-releasing hormone (GnRH). GnRH signals from the hypothalamus regulate the differential secretion of LH and FSH from the anterior pituitary. Exocytosis of FSH and LH from dense core vesicles (DCVs) occurs in response to an intracellular calcium signal, sensed by the synaptotagmins proteins. Various isoforms of synaptotagmins exist and each isoform has varying affinity for calcium, causing calcium-regulated exocytosis to be finely controlled. Because LH and FSH …

Support For The Us Endangered Species Act Is High And Steady Over The Past Three Decades, John Vucetich, Jeremy T. Bruskotter, Robyn Wilson, L. Mark Elbroch, Adam Feltz, Thomas Offer-Westort

Michigan Tech Publications

Conservation professionals expect increased attempts to weaken the US Endangered Species Act (ESA) during the second Trump administration. As such, it is important to understand Americans’ level of support for the ESA. Prior research indicates that support for the ESA remained consistently strong across four studies conducted over a two-decade period, 1996–2015. The research presented here extends those observations to six studies conducted over a three-decade period, 1996–2025. We find that support of the ESA over that period has remained consistently high, at about 84%, and opposition has remained consistently low, at about 12%. We also report on other trends …

Neural Oscillations Enable Concurrent Visual Perception And Visual Working Memory Processing, Khayla Santiago Jun 2025

Neural Oscillations Enable Concurrent Visual Perception And Visual Working Memory Processing, Khayla Santiago

Lawrence University Honors Projects

Successful goal-directed behavior requires balancing task-relevant information stored in working memory and the continuous processing of incoming sensory input, yet the neural mechanisms underlying this coordination remain unclear. This study examines how neural oscillations support concurrent visual perception and visual working memory. Using electroencephalography (EEG), we recorded brain activity while participants performed a dual task paradigm requiring them to simultaneously maintain one orientation in their memory while monitoring another orientation on the screen. After variable time intervals (50 different SOAs between 500-1500ms), participants compared a probe against either the memorized or visually monitored orientation. Analysis of response times and accuracy …


Evolutionary Conservation Of Wiskott-Aldrich Syndrome Protein In Clarthrin-Mediated Endocytosis, Jonah Friedmann Jun 2025

Evolutionary Conservation Of Wiskott-Aldrich Syndrome Protein In Clarthrin-Mediated Endocytosis, Jonah Friedmann

Lawrence University Honors Projects

Clathrin-mediated endocytosis (CME) is a cellular process for internalizing extracellular materials and recycling parts of the plasma membrane into intracellular vesicles. When a threshold of membrane-bound receptors is met at the cell surface, endocytic proteins organize into a conformation that can invaginate the membrane and separate a vesicle into the cytosol. Our current model for understanding CME has been derived from studies in Saccharomyces cerevisiae. Previous research has led to a model for how Las17, a homolog of Wiskott Aldrich Syndrome Protein (WASP), contributes to CME. WASP proteins are critical actin nucleators involved in multiple processes. In S. cerevisiae, Las17 …

1 Herpes Simplex Virus Type 1 And Apolipoprotein-E In Alzheimer’S Disease: Virus Entry And Innate Immunity, Jim Camilleri

College of Science and Health Theses and Dissertations

Herpes simplex virus type 1 (HSV-1) is a neurotropic virus that has been detected in brains affected by Alzheimer’s Disease (AD), the leading global cause of cognitive decline. In vitro and epidemiological studies support a role for HSV-1 in AD. The strongest genetic risk factor for late-onset AD is the E4 allele of APOE, which codes for apolipoprotein-E (ApoE), a protein that mediates brain cholesterol homeostasis. Previous work has suggested that ApoE can affect HSV-1 entry into cells; however, APOE has three alleles (E2, E3, and E4) and allelespecific effects of ApoE on HSV-1 entry remain undetermined. We hypothesized that …

The ability to deliver a therapeutic sequence to a specific cell type in the human brain would make possible innumerable therapeutic options for some of our most challenging diseases; however, studies on adeno-associated virus (AAV) vector tropism have generally relied on animal models with limited translational utility. For this reason, establishing the tropism of common adeno-associated virus (AAV) vectors in living human brain tissue serves as an important baseline for further optimization, as well as a determination of human brain cell types transduced by clinically approved gene therapy vectors AAV2 and AAV9. We have adapted an

Theses and Dissertations

INTRODUCTION: Pregnant women have an elevated risk of developing lower limb musculoskeletal disorders, likely due to the rapid increase in body mass and joint laxity. While a few studies have evaluated changes in static foot posture due to pregnancy, it is unclear if body mass or joint laxity is the primary driver. Additionally, how pregnancy affects the mechanics of the foot during dynamic movements is still not understood. PURPOSE: The purpose of this study is to investigate the foot's response to pregnancy. First, we examined foot tissue characteristics across pregnancy, specifically plantar fascia (PF) stiffness, length, and thickness. Additionally, we …


Anthropogenic Litter In Freshwater Ecosystems: Effect On Ecosystem Processes And Spatial Distribution, Emily Johnson Jun 2025

Anthropogenic Litter In Freshwater Ecosystems: Effect On Ecosystem Processes And Spatial Distribution, Emily Johnson

Master's Theses

The rapid increase of plastic production and disposal into the environment has resulted in anthropogenic litter (i.e., trash; AL) becoming a global problem. In aquatic ecosystems, macro- and microplastics are long-lived, mobile, and interact with the physical and chemical components of aquatic ecosystems. Our objectives were to: (1) assess the impact of microplastic pollution on the ecosystem processes of ecosystem metabolism and N2 flux in an oligotrophic lake and (2) to assess the abundance and assemblage of anthropogenic litter in a large urban river. For objective (1), we added microplastics at a range of concentrations to littoral mesocosms. Ecosystem metabolism …

Correlative studies have linked human gut microbes to specific health conditions. Alistipes is one such microbial genus negatively linked to inflammatory bowel disease (IBD). However, the protective role of Alistipes in IBD is understudied, and the underlying molecular mechanisms remain unknown. In this study, colonization of Il10-deficient mice with Alistipes timonensis DSM 27924 delays colitis development. Colonization does not significantly alter the gut microbiome composition, but instead shifts the host plasma lipidome, increasing phosphatidic acids while decreasing triglycerides. Outer membrane vesicles (OMVs) derived from Alistipes are detected in the plasma of colonized mice, carrying potentially immunomodulatory metabolites into the …

All biological processes, from embryonic development to cancer, are tightly controlled by the interactions between genetics and epigenetics. An array of epigenetic modifications, such as DNA methylation, histone/chromatin modifications, and noncoding RNA-mediated targeting, are essential to regulate the heritable changes that occur during multiple cellular processes. A failure in proper regulation results in inappropriate gene expression that ultimately leads to pathological states. Groundbreaking advances in genomics and transcriptomics have revealed the potential involvement of epigenetics in various physiological and pathological states. The promising clinical and preclinical results shown by epigenetics drugs further underscore the central role of epigenetics in multiple …

Faculty, Staff and Student Publications

Helix pomatia AMP deaminase (HPAMPD), an enzyme enriched in the foot muscle of the mollusk H. pomatia, exhibits deaminase activity on adenosine-5'-monophosphate (AMP). HPAMPD is the first member of the adenosine deaminase-related growth factor (ADGF) family to prefer the nucleotide AMP over the nucleoside adenosine. To investigate the substrate selectivity of HPAMPD, we determined its structure in both the apo form and in complex with the adenosine analogs pentostatin and pentostatin-5'-monophosphate. Structurally, HPAMPD adopts a fold similar to human ADA2, an ADGF family member. HPAMPD has acquired the ability to interact with the 5'-monophosphate group of AMP through polar and …

Understanding how genetic disorders affect CD8+ T cells in the tumor microenvironment is key to improving cancer immunotherapy. Individuals with sickle cell disease (SCD), the most prevalent inherited blood disorder, have a higher risk of developing certain cancers than the general population, but the mechanisms driving this increased risk remain unclear. Our study revealed that SCD altered CD8+ T cell 3D genome architecture, triggering ferroptosis and weakening anti-tumor immunity, thereby promoting tumor growth. Using murine and humanized SCD models, we found that disrupted chromosomal interactions in CD8+ T cells reduced the expression of anti-ferroptotic genes, including SLC7A11 and hydrogen sulfide …
