Department of Radiation Oncology Posters

Background

• Alpha-emitting radionuclides show promise for targeted radiopharmaceutical therapy (TRT).
• High linear energy transfer and short range cause highly localized DNA damage for effective cancer cell eradication.
• However, distributions of radioactivity and absorbed dose on the cellular scale remain elusive.
• Progress toward understanding α-TRT radiobiologic response, evaluating novel α-TRT drug efficacy, and optimizing administration for personalized treatments will require knowledge of radioactivity and absorbed dose distributions.
• A novel real-time α camera, the ionizing radiation quantum imaging detector (iQID), has successfully mapped the microdistribution of α-emitting radionuclides in mouse and human tissues [1].

Jingle’ And ‘Jangle’ Fallacies

The International Journal of Ecopsychology (IJE)

Systematic approaches (theories and applications) from early founders of the social sciences and education, even in their early history, paid meticulous attention to the many pitfalls encountered when neglecting to clarify and specify what one means when using words which imply “constructs” and their purported cause and effect dynamics. ‘Jingle’ and ‘jangle’ fallacies, when finally spotted and addressed, turn out to be the naiveté of a person not understanding the terms/words they were using. They failed to notice, according to Thorndike and Woodworth that words are (1901), “… mythological, not real entities. The words do not mean any existing fact …

Residual Stroke Risk Among Patients With Atrial Fibrillation Prescribed Oral Anticoagulants: A Patient-Level Meta-Analysis From Combine Af, Linda Johnson, Alexander Benz, Ashkan Shoamanesh, John W Eikelboom, Michael Ezekowitz, Robert Giugliano, Lars Wallentin, Christian Ruff, Renato Lopes, Sanjit Jolly, Richard Whitlock, Christopher Granger, Stuart Connolly, Jeffrey Healey

Physiological Role For S-Nitrosylation Of Ryr1 In Skeletal Muscle Function And Development, Qi-An Sun, Zachary W. Grimmett, Douglas T. Hess, Zhaoxia Qian, Ruchi Chaube, Nicholas M. Venetos, Bradley N. Plummer, Kenneth R. Laurita, Richard T. Premont, Jonathan S. Stamler

Faculty Scholarship

Excitation-contraction coupling in skeletal muscle myofibers depends upon Ca2+ release from the sarcoplasmic reticulum through the ryanodine receptor/Ca2+-release channel RyR1. The RyR1 contains ∼100 Cys thiols of which ∼30 comprise an allosteric network subject to posttranslational modification by S-nitrosylation, S-palmitoylation and S-oxidation. However, the role and function of these modifications is not understood. Although aberrant S-nitrosylation of multiple unidentified sites has been associated with dystrophic diseases, malignant hyperthermia and other myopathic syndromes, S-nitrosylation in physiological situations is reportedly specific to a single (1 of ∼100) Cys in RyR1, Cys3636 in a manner gated by pO2. Using mice expressing a form …

IL17 is required for the initiation and progression of pancreatic cancer, particularly in the context of inflammation, as previously shown by genetic and pharmacological approaches. However, the cellular compartment and downstream molecular mediators of IL17-mediated pancreatic tumorigenesis have not been fully identified. This study examined the cellular compartment required by generating transgenic animals with IL17 receptor A (IL17RA), which was genetically deleted from either the pancreatic epithelial compartment or the hematopoietic compartment via generation of IL17RA-deficient (IL17-RA-/-) bone marrow chimeras, in the context of embryonically activated or inducible Kras. Deletion of IL17RA from the pancreatic epithelial compartment, but not from …

Changes In Multimorbidity Among Hospitalized Adults In The Us, Christine Loyd, Lauren Picken, Richelle Sanders, Yue Zhang, Richard E. Kennedy, Cynthia J. Brown

School of Medicine Faculty Publications

OBJECTIVE: This investigation examines burden of comorbidity measured by the Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI) among inpatients based on age, sex, and race. METHODS: Cross-sectional analysis of 2012-2018 US NIS datasets. Participants were inpatients 55y+. ICD-9/10 codes for admitting diagnoses were used to calculate disease burden using the CCI and ECI. Unweighted mean CCI and ECI scores were compared across demographic variables. RESULTS: An increase in mean CCI and ECI scores across age, sex, and races (p < .001) was identified. Compared to the youngest age group (55-59y), all age groups had higher mean CCI and ECI adjusting for time (p < .001). Increases were greatest in older age groups until age 80-84 for CCI and 85-89 for ECI. The female group had lower CCI adjusting for time (p < .001) compared to males. There was no difference between sex groups in mean ECI (p=.409). Compared with the White group, all other race groups had higher mean CCI adjusting for time (p < .001). Black inpatients had the highest CCI followed by Native American inpatients. Findings were similar for ECI, but with no difference between Hispanic and White groups (p=.434). CONCLUSIONS: Growing multimorbidity burden among adult inpatients across age, sex, and race supports the continued need for programs for preventing and reducing multimorbidity, especially among communities that experience health inequity including older, Black, and Native American patients.

Supporting Students’ Physical Activity Self-Efficacy Within High School Physical Education, Ken Murfay, Aaron Beighle, Heather Erwin, Erin Aiello, Sarah Pyszczynski

International Journal of Physical Activity and Health

Research examining physical activity (PA) is significant because of the known benefits of PA. Studying high school (HS) students is particularly important due to the consistent decline in PA as students age. One strategy to increase PA is to increase someone’s self-efficacy (confidence) to be physically active which is commonly positively associated with PA. Most of the research on how to support physical activity self-efficacy (PASE) comes from outside-of-school interventions with minimal literature on how to support students’ PASE within HS physical education (PE). This study attempted to identify and share practices that current HS PE teachers were implementing to …

Staff and Researcher Publications

This study focuses on the discovery of a single-component molecular resist for extreme ultraviolet (EUV) lithography by employing the ionizing radiation-induced decomposition of carbon–fluorine chemical bonds. The target material, DHP-L6, was synthesized by bonding perfluoroalkyl ether moieties to amorphous dendritic hexaphenol (DHP) with a high glass transition temperature. Upon exposure to EUV and electron beam irradiation, DHP-L6 films exhibited a decreasing solubility in fluorous developer media, resulting in negative-tone images. The underlying chemical mechanisms were elucidated by Fourier transform-infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy, and nanoindentation experiments. These analyses highlighted the possible electron-induced decomposition of C–F bonds in DHP-L6, leading …

Tomivosertib Reduces Ectopic Activity In Dorsal Root Ganglion Neurons From Patients With Radiculopathy, Yan Li, Megan L Uhelski, Robert Y North, Juliet M Mwirigi, Claudio E Tatsui, Kathleen E Mcdonough, Juan P Cata, German Corrales, Greg Dussor, Theodore J Price, Patrick M Dougherty

Faculty, Staff and Student Publications

Spontaneous activity in dorsal root ganglion (DRG) neurons is a key driver of neuropathic pain in patients suffering from this largely untreated disease. While many intracellular signalling mechanisms have been examined in preclinical models that drive spontaneous activity, none have been tested directly on spontaneously active human nociceptors.

Using cultured DRG neurons recovered during thoracic vertebrectomy surgeries, we showed that inhibition of mitogen-activated protein kinase interacting kinase (MNK) with tomivosertib (eFT508, 25 nM) reversibly suppresses spontaneous activity in human sensory neurons that are likely nociceptors based on size and action potential characteristics associated with painful dermatomes within minutes of treatment. …
