Enhancing Cardiomyocyte Resilience To Ischemia-Reperfusion Injury: The Therapeutic Potential Of An Indole-Peptide-Tempo Conjugate (Iptc), Shanshan Hou, Xin Yan, Xiang Gao, Steffen Jockusch, K. Michael Gibson, Zhiying Shan, Lanrong Bi

Michigan Tech Publications

Ischemia/reperfusion (I/R) injury leads to apoptosis and extensive cellular and mitochondrial damage, triggered by the early generation and subsequent accumulation of mitochondrial reactive oxygen species (mtROS). This condition not only contributes to the pathology of I/R injury itself but is also implicated in a variety of other diseases, especially within the cardiovascular domain. Addressing mitochondrial oxidative stress thus emerges as a critical therapeutic target. In this context, our study introduces an indole-peptide-tempo conjugate (IPTC), a compound designed with dual functionalities: antioxidative properties and the ability to modulate autophagy. Our findings reveal that IPTC effectively shields H9C2 cardiomyocytes against hypoxia/reoxygenation (H/R) …

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 …

Neuronal Control Of Posture In Blind Individuals, I. Helmich, R. Gemmerich

Exercise and Sport Studies: Faculty Publications

The control of posture is guided by the integration of sensory information. Because blind individuals cannot apply visual information to control posture as sighted individuals do they must compensate by the remaining senses. We therefore hypothesize that blind individuals alter their brain activation in the sensorimotor cortex during postural control to compensate for balance control without vision by the increased integration of somatosensory information. Ten blind and ten sighted (matched) individuals controlled posture during conditions with (I) eyes closed / open, and (II) stable / unstable surface conditions. Postural sway was recorded by applying a pressure distribution measuring plate. Brain …
