The Impact Of Sex And Heat Exposure Schedule On Heat Acclimation, Alejandro M. Rosales, Brent C. Ruby

UM Graduate Student Research Conference (GradCon)

Females are underrepresented in thermoregulatory research and thus there is a need to examine how sex-related differences impact heat acclimation. Moreover, current global heatwave incidences warrant investigation into optimizing strategies for human tolerance to heat. PURPOSE: Determine how sex and temporally partitioning identical heat exposure time impacts heat acclimation. METHODS: Over a week, 30 females and 30 males were heat acclimated daily (38°C, 60% RH) on a treadmill (1.6 m·s^-1, 5% grade) in one of two 90-minute exposure groups. Sustained groups completed 90-minute sessions continuously and periodic groups completed three separate 30-minute sessions 3 hours apart. Heat exposure …

Uca1 As A Key Regulator Of The Warburg Effect During Anoikis Resistance In Colorectal Cancer Metastasis, Ricardo Pequeno Bracho, Salique Hassan Shaham, Yamile Abuchard Anaya, Sophia Leslie, Kyle Doxtater, Subhash Chauhan, Bilal Hafeez, Tamer Oraby, Manish K. Tripathi

Research Symposium

Colorectal carcinoma (CRC) is the second leading cause of cancer-related mortality in the United States. While localized CRC has a 90% five-year survival rate, this drops sharply to 14% upon metastasis. Metastasis occurs in approximately 40–50% of CRC cases and requires cancer cells to acquire anoikis resistance—a critical adaptation allowing survival after detachment from the extracellular matrix, enabling migration and colonization of secondary sites. Understanding the molecular mechanisms driving anoikis resistance, particularly those linked to altered glucose metabolism, is essential for developing targeted therapies for metastatic CRC.

Cancer cells frequently exhibit the Warburg Effect, a metabolic adaptation favoring glycolysis over …

Impacts Of The Coastal Aquaculture Authority (Amendment) Act And Adaptive Capacity In The Social-Ecological System Of Chilika Lagoon, India, Adyasha Nayak

UM Graduate Student Research Conference (GradCon)

The growing demand for seafood in the global North has led to transition of capture fisheries to aquaculture to meet the demand. While this growth has been considered a success for livelihood development, its negative impacts on small-scale and traditional fisheries offset the benefits.

This is evident in the case of Chilika lagoon on the east coast of India. Chilika lagoon is a natural habitat for Indian prawn (Penaeus indicus) and thus attracted commercialization during the aquaculture boom. Starting in the 1980s, encroachment of aquaculture and proliferation of commercial fishing has led to loss of traditional fishing areas …

Assessing The Micro- And Macroscopic Changes Of Taphonomically Altered Bone, Shelby Feirstein

UM Graduate Student Research Conference (GradCon)

Forensic identifications may be hampered when perpetrators find unique ways of obscuring their victims’ identities, such as fire and household corrosive substances. Thermal alteration, sodium hydroxide, and hydrochloric acid are known to change both the structural integrity and composition of skeletal elements; but the patterns of these processes, nor how each may affect the potential for obtaining identifying DNA data, are well understood.

Burned bone concomitantly follows a defined color spectrum and eventually reaches calcination, consisting only of its original inorganic mineral, hydroxyapatite, which is naturally white in color and brittle.

In contrast, analyses of chemical exposure focus on total …

Medication-Assisted Treatment For Opioid Use Disorder In Montana: Barriers And Best Practices, Lindsey Hundemer, Jacqueline Kline

UM Graduate Student Research Conference (GradCon)

Medication-assisted treatment (MAT) is an evidence-based approach for opioid use disorder (OUD) using medications like buprenorphine, methadone, and naltrexone to treat symptoms of OUD and withdrawal. Despite reducing opioid-related deaths by 50% and improving employment, criminal activity, and birth outcomes, its acceptance in Montana's substance use disorder (SUD) housing varies. Experts stress MAT as essential medical care, yet stigma-driven policies still restrict access, forcing some to choose between medication and treatment.

This study explores the landscape of MAT acceptance in Montana SUD treatment facilities, highlighting the barriers that prevent its widespread acceptance, differences regarding treatment duration, approved medications, and administration …

Late! I’M Late For A Very Important Physics Update I’M Late! I’M Late For A Very Important Physics Update, Caterina Erdas

Osmosis Magazine

Modern physics is my only class where half the students are consistently late. It’s not a forgivable one or two minutes late, but five to fifteen. I say this as a culprit myself; I slept in late on the third day of class and didn’t go. It’s ironic, considering we spend a good portion of lecture re-defining time.

Michigan Tech Publications

The ethylene-forming enzyme (EFE) from the fungus Penicillium digitatum strain Pd1 was heterologously produced in Escherichia coli and its properties were compared to the extensively characterized bacterial enzyme from Pseudomonas savastanoi strain PK2. Both enzymes catalyze four reactions: the conversion of 2-oxoglutarate (2OG) to ethylene and CO₂, oxidative decarboxylation of 2OG coupled to _L-arginine (_L-Arg) hydroxylation, uncoupled oxidative decarboxylation of 2OG, and the production of 3-hydroxypropionate (3-HP) from 2OG. The strain Pd1 enzyme exhibited a greater ratio of ethylene production over _L-Arg hydroxylation than the PK2 strain EFE. The uncoupled decarboxylation of 2OG and …

Geosciences Faculty Publications

At the end of the Cretaceous, the massive Deccan trap (DT) volcanic eruptions are regarded as the primary driver of global climate deterioration. Accurate age models are key to unravel the sequence of events related to DT volcanism onset and effects on the global climate system. We establish a direct geochemical link between DT volcanism as recorded in marine osmium isotopic data and global climate change documented in benthic foraminifera carbon and oxygen isotope records. Based on our state-of-the-art astronomically calibrated age model, two major shifts in marine ¹⁸⁷Os/¹⁸⁸Os at 66.49 and 66.28 million years ago are …

Future Applications Of Fluorescence Lifetime Imaging Ophthalmoscopy In Neuro-Ophthalmology, Neurology, And Neurodegenerative Conditions, Daniel M. Markowitz, Elizabeth Affel, György Hajnóczky, Robert C. Sergott

Farber Institute for Neuroscience Faculty Papers

Fluorescence lifetime imaging ophthalmoscopy (FLIO) has emerged as an innovative advancement in retinal imaging, with the potential to provide in vivo non-invasive insights into the mitochondrial metabolism of the retina. Traditional retinal imaging, such as optical coherence tomography (OCT) and fundus autofluorescence (FAF) intensity imaging, focus solely on structural changes to the retina. In contrast, FLIO provides data that may reflect retinal fluorophore activity, some of which may indicate mitochondrial metabolism. This review builds upon the existing literature to describe the principles of FLIO and established uses in retinal diseases while introducing the potential for FLIO in neurodegenerative conditions.

The Intricacies Of Pairwise Modular Multiplicative Inverse In Lucas Numbers, Charles Liu

Rose-Hulman Undergraduate Mathematics Journal

Let (p,q) be a pair of relatively prime integers greater than 1. The pairwise modular multiplicative inverse (PMMI) of (p,q) is defined as the unique pair of positive integers (p′, q′) such that p p′ ≡ 1 (mod q), p′ < q, qq′ ≡ 1 (mod p), q′ < p. In this paper, we determine all pairs of Lucas numbers such that their PMMIs are pairs of Lucas numbers.

Discounting Effect Size When Borrowing External Data In Clinical Studies, Zhuanzhuan Ma, Chul Ahn, Bin Wang, Xuefeng Li

Research Symposium

Background: When borrowing information from external data to augment a current trial, many available methods discount the sample size but retain the effect size from previous studies. Discounting the sample size is just one way to discount the prior information. It may not be appropriate if the underlying assumption of unbiased treatment effect does not hold, for example, when the treatment effect in the historical study is likely higher than the one expected in the current trial.

Methods: To tackle this potential issue, we study some methods to shrink the effect size from previous studies assuming that the prior effect …

Sparse Bayesian Variable Selection Using Global-Local Shrinkage Priors For The Analysis Of Cancer Datasets, Zhuanzhuan Ma

Research Symposium

Background: With a rapid development of data collection technology, high dimensional data, whose model dimension k may be growing or much larger than the sample size n, is becoming increasingly prevalent in different fields of study, such as ecology, genetics, among others. This data deluge is introducing new challenges to traditional statistical procedures and theories and is thus generating a renewed interest in the problems of variable selection and classification in high dimensional regression models. In large k, small n settings, variable selection is usually the first step for dimension reduction to uncover significant covariates, which contribute to …

Effects Of Fertilization And Liming On The Improvement Of Native Pastures, Maria E.V Lourenco, R.J. M. De Carvalho, Maria De L.A.P Da Silva

IGC Proceedings (1977-2023)

Native pastures in Portugal have relatively low productivity. The yield and botanical composition of such grasslands, where some legumes species are present, can be improved by fertilization with phosphorus application and/or also liming (Carter, 1983). The presence of legumes in pasture can also be improved by molybdenum application (Lattan et al., 1984). Significant increases of phosphorus concentration in plants (Garden et al., 1978) and on soil available phosphorus (Gregan et al., 1980) due to phosphorus application have also been reported.

The objectives of this study were to evaluate the potential of such treatments on the improvement of native pastures.
