Students and faculty from the Department of Kinesiology and Integrative Physiology (KIP) recently attended the 2023 American Physiology Summit in Long Beach, CA on April 20–23, 2023. PhD students Greg Miodonski, Sherry Chen, Kyle Wehmanen, and Isaac Wedig presented posters to their colleagues at the annual event.
Greg, a member of Dr. Qinghui Chen’s lab, did a poster presentation of his research project entitled “Exercise Augments Small Conductance Ca2+ -Activated Potassium Channel (SK) Function in the PVN of Sprague Dawley Rats to Reduce Sympathetic Outflow.” His poster was selected as “top 10% scoring abstracts” sponsored by APS Central Nervous Session (CNS). Read more about his research in his abstract below.
Congratulations to these students for a wonderful showing at the summit!
Greg’s Abstract:
“Exercise Augments Small Conductance Ca2+ -Activated Potassium Channel (SK) Function in the PVN of Sprague Dawley Rats to Reduce Sympathetic Outflow”

Elevated sympathetic outflow is a key feature of cardiovascular disease (CVD) that worsens disease progression. Our lab has shown that SK channels expressed in the PVN play a crucial role in regulating neuronal activity and sympathetic outflow, and that SK channels become dysfunctional in rats fed a high salt diet. Exercise has been shown to be an effective treatment for reducing sympathoexcitation in CVD including hypertension and heart failure, but the underlying mechanisms are not fully understood. We hypothesized that aerobic exercise would upregulate SK channel function in the PVN to reduce sympathetic nerve activity (SNA). To test this, 5–6 week old Sprague Dawley rats were randomly divided into sedentary (SED) and exercise (EXT) two groups and fed a 0.4% NaCl normal salt diet. Following acclimation, EXT groups ran on a motorized treadmill 5 days/week for 8-10 weeks. Conscious blood pressure was measured weekly via tail plethysmography. After 8-10 weeks, animals were anesthetized and underwent in vivo surgery to record the renal sympathetic nerve activity (RSNA) and mean arterial pressure (MAP) following PVN microinjection of the SK blocker, apamin (0.25mM, 60nL/side). The data showed that the RSNA response to PVN apamin was significantly enhanced in EXT rats compared with SED rats (320.8 ± 174.6 % baseline, n=9 vs 184.8 ± 143.1 % baseline, n=9; p = 0.02). The corresponding ABP response to apamin was not significantly different in EXT rats compared with SED rats (20.40 ± 9.98 mmHg, n=9 vs 25.27 ± 9.97 mmHg, n=8; p = 0.1658). Our data indicates exercise enhances PVN SK channel function to reduce sympathetic outflow. This improvement of SK channel function may be one mechanism by which exercise reduces SNA in CVD including hypertension and heart failure.

Undergraduate and graduate students in the Kinesiology and Integrative Physiology Department are encouraged to apply for the 2023 Songer Research Award for Human Health. Matthew Songer, (Biological Sciences ’79) and Laura Songer (Biological Sciences ’80) established these awards to stimulate and encourage opportunities for original research by current Michigan Tech students.
Students may propose an innovative medically-oriented research project in any area of human health. The best projects will demonstrate the potential to have a broad impact on improving human life. This research will be pursued in consultation with faculty members within the College of Sciences and Arts. The Songers’ gift and matching funds from the College will support two awards for undergraduate research ($4,000) and two for graduate research ($6,000), for research conducted over the Summer of 2023 and/or the following academic year.
Learn more about who is eligible to apply, how to apply, and how the funds may be used.
Submit applications as a single PDF file to the Office of the College of Sciences and Arts by 4:00 p.m. Monday, April 24, 2023. Applications may be emailed to djhemmer@mtu.edu. Any questions may be directed to David Hemmer (djhemmer@mtu.edu).
PhD student Ashley Hawke received the Gallagher Award at the 2023 National Safe Patient Handling and Mobility Education Event that took place in Glendale, AZ from March 20-23, 2023. This national event is hosted by the Association of Safe Patient Handling Professionals.
The award Ashley received is for her project proposal entitled “Effectiveness of Patient Handling Interventions on Reducing Musculoskeletal Disorder Risk in Healthcare Workers: A Study Proposal.” Below is her project’s abstract to learn more about Ashley’s work.
Background: Musculoskeletal disorders (MSDs) are extremely prevalent among healthcare workers, especially those who perform patient handling tasks. Previous research has found that sustained static and/or awkward working postures, frequent bending, repetitive and/or forceful work, and twisting were commonly associated with MSDs. The use of mechanical assistive devices reduces risks of MSDs during patient handling; however, availability and accessibility of equipment are common barriers to using these devices in clinical settings. Portable passive interventions, such as transfer slings, slider sheets, and exoskeletons have been proposed to assist with patient handling tasks as an alternative to mechanical assistive devices, but the effectiveness of these interventions in reducing MSD risk in healthcare workers is inconclusive. METHODS: In the proposed study, we will evaluate three passive patient handling interventions (transfer sling, slider sheet, and passive back-assist exoskeleton) in their ability to alter biomechanical and physiological responses associated with the development of MSDs when performing two standardized patient handling tasks: 1) turning a patient onto their side and 2) performing a sit to sit transfer. Twenty participants will be recruited to perform the tasks using an 80 kg mannequin in four different interventions: manual, using a transfer sling, using a slider sheet, and wearing a passive exoskeleton. Variables to be measured include muscle activity of the trunk, upper extremity, lower extremity muscles, shoulder/lumbar kinematics, kinetics, oxygen consumption, heart rate, energy expenditure, and rating of perceived exertion. FINDINGS: As this is a study proposal, no results are available at this time. CONCLUSIONS/IMPLICATIONS: Results from the proposed study will allow researchers to evaluate the biomechanical demands and physiological cost of each patient handling intervention and how together these may play a role in potentially reducing MSDs. Importantly, these findings may serve as a first step to developing more cost-effective and portable patient handling interventions.

He wrote and published this article while still a PhD student at MTU along with his advisor and co-author Dr. William Cooke.
The AJP-Heart and Circulatory 2023 Best Research Article Award is based on:
He will receive both an award and cash prize at the upcoming American Physiology Summit 2023 to be held April 20-23, 2023 in Long Beach, California.
Dr. William Cooke (KIP), Dr. Carolyn Duncan (KIP), and Dr. Kevin Trewartha (CLS/KIP) were among 12 researchers from Michigan Tech who met with colleagues representing the College of Human Medicine at Michigan State University on March 13, 2023. Hosted by MSU in Grand Rapids, Michigan, this was the inaugural event of the collaborative research symposium between the universities.
Dr. Duncan and Dr. Trewartha presented during the “Neurological Disease and Aging Research” session, while Dr. Cooke presented at the “Cardiovascular Research” session.
In the fall, Michigan Tech will host the second symposium with Dr. Cooke as a co-sponsor. “This is an important collaborative opportunity, and I look forward to being among those who will be organizing the next collaborative meeting on October 27th–beautiful time to be in the UP,” he remarked when asked about the future event.
