Terahertz Electromagnetic Effects And Chirality-Induced Spin Selectivity In Dna, F. Matthew Mihelic Md

Faculty Publications

The effects of terahertz electromagnetic stimulation of the DNA molecule can be understood through modeling of the quantum logical mechanics of the DNA molecule.  Coherent conduction of electron spin states along the aromatic nucleotide base pairs and chirality-induced spin selectivity are two characteristics of the DNA molecule that are involved in the precise separation of the double-stranded DNA molecule at a specific location.  Such modeling can inform predictions of DNA strand separation and has significant implications for understanding DNA transcription bubble formation.

Musical Training Increases Anticipatory Responding And Predictive Control In Sequence Learning, Li Ann Leow, Jarrad Lum, Sara Johnson, Emily Corti, Welber Marinovic

Research outputs 2022 to 2026

Musicians demonstrate advantages in acquiring motor sequences, showing faster learning and better explicit sequence knowledge than non-musicians. However, it is unclear whether this advantage extends beyond acquisition to the consolidation phase, which is when newly learned skills stabilize and become resistant to interference. Additionally, while interference from executing competing motor tasks is well-established, less is known about whether purely sensory information presented after learning can disrupt consolidation of a bimodal motor sequence. We investigated how post-acquisition sensory interference affects performance of a learned audio-visual sequence, and whether musical training moderates this vulnerability. Participants first learned an explicit sequence in a …

Characterization Of Catechol-Type Siderophore(S) From P. Mosselii Cfml 90-83, Kemper R. Rasnake

Electronic Theses and Dissertations

Iron is essential for many biological processes, where it is used as a cofactor. Even though it is abundant in the Earth’s crust, it is in an insoluble form unavailable to microorganisms in the soil. To overcome this, bacteria produce siderophores, which are secondary metabolites that have a high affinity for iron. This allows bacterial cells to obtain insoluble iron that is essential for survival. Pseudomonas mosselii, a Gram negative bacterium, was isolated from soil. It was selected for further analysis as it was found to produce siderophore(s) under iron-limited conditions, which have not been characterized previously. Therefore, we aimed …

Acute myeloid leukemia (AML) is an aggressive hematological malignancy with various molecular and cytogenetic subtypes. Treatment options for older adult patients are limited due to high toxicity of conventional chemotherapy. The B-cell leukemia/lymphoma 2 inhibitor venetoclax is effective in combination with hypomethylating agents or low-dose cytarabine, but ∼30% of patients do not respond to the initial combination treatment. Thus, alternative combinations are needed to sensitize AML cells to venetoclax and overcome resistance mechanisms. Here, we report that targeting histone lysine-specific demethylases induces a ferroptosis-like phenotype driven by oxidative stress in various AML subtypes. In both patient samples and cell lines, …

Objective: To identify proteomic signatures underlying 3-year progression from impaired fasting glucose (IFG) to diabetes.

Research design and methods: We examined IFG progression in the Atherosclerosis Risk in Communities (ARIC) study from visit 2 (1990-1992) to visit 3 (1993-1995). We tested associations of 4,955 plasma proteins (SomaScan version 4.0) with ∼3-year progression from IFG (FG 100-125 mg/dL without diabetes) to diabetes (diagnosis, medication, or FG ≥126 mg/dL) using logistic regression models adjusted for demographics, cardiometabolic risk factors, and baseline glucose with Bonferroni correction (P < 10-5). We explored biological pathways enriched among the top proteins and calculated improvements in prediction (ΔAUC and net reclassification using 3-year risk thresholds of 6% and 15% in 80% training and 20% internal validation subsamples). We validated results in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort.

Results: There were 3,786 ARIC participants with IFG (mean [SD] age 57 [6] years, 52% female, …

Rates Of, Reasons For, And Reactions To Discontinuation Of Glp-1 Receptor Agonists: A Narrative Review, Henry D Heisey, L Parker Gregg, Christopher D Verrico, Dennis T Villareal, Terri L Fletcher

Faculty, Staff and Students Publications

GLP-1RAs are increasingly used for their glucose-lowering and weight-management effects, but many patients discontinue them. In this narrative review we aim to review real-world, quantitative and qualitative GLP-1RA discontinuation, adherence, and persistence evidence as it aligns with an established conceptual framework for understanding medication adherence in noncommunicable chronic disease. Many inconsistencies exist in how discontinuation, adherence, and persistence are studied in this literature. Few qualitative studies have focused on discontinuation of GLP-1RAs. Quantitative approaches often focus on medication-related factors and more superficial aspects of socioeconomic and condition-related factors. Very few studies encompass all 5 dimensions of the medication adherence conceptual …

Background and objectives: The apolipoprotein E (APOE) haplotypes are known to be associated with dementia, with the ε4 haplotype associated with higher risk. It has been suggested that the APOE ε2 allele serves as a protective factor for dementia. However, data on the effects of the homozygous APOE ε2/ε2 genotype are limited, likely due to the rarity of the APOE ε2/ε2 genotype. Furthermore, the association between APOE genotypes and dementia may differ across self-reported race. We aim to investigate the association between APOE genotypes and dementia overall and across self-reported race, with a focus on the potential protective …

Large-scale multiancestry genome-wide association studies have identified hundreds of loci associated with type 2 diabetes (T2D) and glycemic traits, yet imputed genotyping arrays limit the detection of low-frequency and rare variants. Whole-genome sequencing (WGS) offers a more complete view of genetic variation, especially across diverse populations. We analyzed high-coverage (38×) WGS data from 21,913 T2D case subjects, 61,036 control subjects, and up to 50,011 individuals with no diabetes with fasting glucose, fasting insulin, and HbA1c from the National Heart, Lung, and Blood Institute Trans-Omics for Precision Medicine Program. We performed single-variant association testing, conditional analysis, fine-mapping, and Bayesian colocalization to …

Ai-Driven Segmentation And Volumetric Response Modeling Of Liver Regions To Radiotherapy, Aashish Chandra Gupta

Dissertations and Theses (Open Access)

In liver-directed radiotherapy (RT), liver regions receiving higher doses typically undergo atrophy while contralateral/adjacent lower-dose regions may exhibit compensatory hypertrophy through regeneration of healthy tissue. Optimizing the RT plan to promote regional hypertrophy while minimizing the risk of developing atrophy has the potential to enhance post-RT liver function and long-term survivorship. However, current clinical practice largely relies on global liver dose-volume metrics during RT-planning, which may obscure favorable dose-response correlation and limit actionable guidance for clinicians. Therefore, we hypothesized that post-RT regional liver response is governed by a combination of region-specific dose-volume and patient clinical features, and that these responses …
