Effects Of Hypobaric Hypoxia During Intermittent Cycling Bouts On Markers Of Acute Kidney Injury, Jacob D. Dawes, Alyssa R. Bailly, Jonathan W. Specht, Christopher B. Hart, Mateo Griego, Marissa Ramirez, Kaia G. Allen, Alexander Smaragdas, Fabiano T. Amorim

International Journal of Exercise Science: Conference Proceedings

Many individuals travel to high altitudes for recreational or occupational purposes. Hypobaric hypoxia (HH) at altitude decreases arterial oxygen saturation (SaO₂), reduces oxygen delivery to tissues, and can adversely affect organ function. Exercise, independent of HH, significantly decreases renal blood flow (RBF). Therefore, performing exercise in HH may further impair oxygen delivery and place additional strain on the kidneys. While the impact of chronic HH on kidneys has been documented, there is limited research on the risk of acute kidney injury (AKI) under these conditions. PURPOSE: To investigate the effects of acute HH exposure during intermittent exercise …

Can Passive Water Immersion Shape Force Production Capacity?, Joonsun Park, Talin Louder

Although evidence remains limited, these neural effects suggest passive immersion may enhance force output capacity. PURPOSE: This study aimed to investigate the acute effects of passive water immersion in a seated position on lower-extremity isometric strength as measured by isometric mid-thigh pull (IMTP) performance on land. METHODS: Thirty-three active young adults (age: 22.64 ± 4.18 years, height: 174.55 ± 10.28 cm, mass: 81.45 ± 18.77 kg) completed both land and water conditions (LC and WC), with pre- and post-tests using within …

Effect Of Previous Night Alcohol On Thermoregulatory And Physiological Strain During Prolonged Physical Work In The Heat, Marissa Ramirez, Jonathan W. Specht, Flavio De Castro Magalhaes, Fabiano Amorim, Whitley C. Atkins

International Journal of Exercise Science: Conference Proceedings

Many occupational workers engage in strenuous physical work in hot environments for prolonged periods, placing them at risk of heat-related illness due to increasing physiological strain identified by increasing core temperature (Tcore) and heart rate (HR). Lifestyle behaviors, such as smoking, caffeine and alcohol consumption, and sleep deprivation, may further exacerbate heat strain and increase susceptibility to heat-related illness. Notably, alcohol consumption the night before work, and the subsequent hangover, may amplify physiological strain by impairing heat dissipation. However, no previous studies have evaluated the impact of alcohol hangover on heat strain during physical work in the heat. PURPOSE: …

Sex-Specific Changes In Pbmc Mitochondrial Respiration Following Acute Exercise, Ryan R. Moon

International Journal of Exercise Science: Conference Proceedings

Exercise-trained individuals exhibit greater immune system function, which may be attributed in part to enhanced peripheral blood mononuclear cell (PBMC) function. Exercise training is a potent stimulator of mitochondrial adaptation, which may help explain improvements in immunity. However, the mechanisms by which exercise acutely modulates PBMCs to promote beneficial adaptations remain unclear. Purpose: The purpose of this study was to test the hypothesis that a single bout of aerobic exercise modulates PBMC mitochondrial function. Methods: Twenty-eight healthy young adults (13 females, 15 males; age 21.84 ± 2.78 years) completed a graded exercise test (VO₂max: 41.4 ± 7.64 ml O₂·kg⁻¹·min⁻¹) followed …

The Association Between Muscular Strength And C-Reactive Protein Among Post-Menopausal Women: Effect Modification By Hormone Replacement Therapy, Sarah Krager, Bethany Barone-Gibbs, Amanda Paluch, Samantha Ehrlich, Amy Miller, William Boyer

International Journal of Exercise Science: Conference Proceedings

Previous studies suggest that the inflammatory marker C-reactive protein (CRP) may be elevated in post-menopausal women taking hormone replacement therapy (HRT). Muscular strength is associated with more favorable CRP profiles. However, this association has not been examined among post-menopausal women on HRT. PURPOSE: This study aims to examine the association of lower leg strength and CRP while considering potential effect modification by HRT using a representative sample of U.S. adults. METHODS: The final sample (n=1,238) included post-menopausal women (≥50 years) who participated in the 1999-2002 National Health and Examination Survey (NHANES).

Armstrong, R. Michael Gower, Igor Roninson Ph.D., Eugenia Broude, Mengqian Chen Ph.D., Hao Ji, Chang-Uk Lim, Hongjun Wang, Daping Fan, Peisheng Xu Ph.D., Hexin Chen

Faculty Publications

Myeloid cells are highly heterogeneous and play key roles in establishing an immunosuppressive tumor microenvironment (TME), but the mechanisms controlling their differentiation remain unclear. Using orthotopic murine breast cancer models, we investigated how interleukin-1α (IL-1α) influences this process. Deletion of host Il1α resulted in rejection of transplanted tumors. Single-cell RNA sequencing identified CX3CR1⁺ macrophages as the main source of IL-1α in the TME. Il1α deficiency disrupted monocyte–macrophage differentiation, reducing CX3CR1⁺ macrophages and increasing iNOS⁺ macrophages. Myeloid cells from Il1α⁻/⁻ hosts induced lower PD-1 and CTLA-4 expression in co-cultured CD8⁺ T cells than those from wild-type hosts. CellChat analysis showed …

Foxo1 Inhibition And Fadd Knockdown Have Opposing Effects On Anticancer Drug-Induced Cytotoxicity And P21 Expression In Osteosarcoma Cells, Danielle Walker, Antanay Hall, Alexis Bonwell, Nancy Gordon, Danielle Robinson, Mario G Hollomon

Faculty, Staff and Student Publications

Forkhead box class O1 (FOXO1) and fas-associated death domain (FADD) regulate cell death pathways and homeostatic processes such as cell cycle progression and apoptosis. FADD phosphorylation promotes nuclear localization of FOXO1, and FOXO1 regulates FADD expression. Therefore, it is plausible that FOXO1 and FADD have synergistic or antagonistic effects on cell cycle regulation and the response to anticancer drug treatment in cancer cells. In the present study, we report that AS1842856-mediated inhibition of FOXO1 reverses anticancer drug-induced cytotoxicity, while FADD knockdown increases anticancer drug-induced cytotoxicity in osteosarcoma (OS). Reversed anticancer drug-induced cytotoxicity was accompanied by G2/M cell cycle arrest and …

Premature Aging In Serious Mental Illness, Breno S Diniz, Gabriel R Fries, Chia-Ling Kuo, Ming Xu, Eric J Lenze

Faculty, Staff and Student Publications

Serious mental illnesses (SMIs), including major depressive disorder, bipolar disorder, and schizophrenia, have long been linked to cognitive decline, multiple chronic medical conditions, and premature mortality. These factors significantly contribute to the severe disability seen in SMIs, extending beyond the severity of psychopathology and indicating a premature aging phenotype associated with these conditions. The mechanisms that underlie the relationship between SMIs and the premature aging phenotype are not well understood, but recent evidence suggests that individuals with SMIs may exhibit accelerated biological aging. In this review, we present a comprehensive analysis of the current literature, demonstrating the potential association of …

Real-Time Hemodynamic Deterioration Following Polymorphic Ventricular Tachycardia In A Patient With Preexisting Aicd Implanted With Lvad, Dhruvil Patel, Maya Guglin, Deepa Iyer, Chonyang Albert, Jagpreet Grewal, Kenneth Dulnuan

The VAD Journal

Ventricular arrhythmias (VAs) are common in patients with a left ventricular assist device (LVAD), but the literature remains inconclusive regarding the benefits of an automatic implantable cardioverter-defibrillator (AICD) in this population, especially in those with a preexisting device before LVAD implantation. Here, we report the acute hemodynamic consequences of polymorphic ventricular tachycardia in a patient with a preexisting biventricular AICD who was implanted with an LVAD (HeartMate 3). This case underscores the importance of considering AICD placement on a case-by-case basis and highlights the need for a well-designed study to establish its benefit in this population.
