Past studies have shown that exercise in the form of high intensity interval training (HIIT) is the "ideal form of exercise to improve health and performance without overstressing the immune system" (Fisher et. al, 2011, p. 5). Additionally, HIIT has been found to promote cardiovascular health and immunity (Fisher et. al, 2011). The proposed study will evaluate the neuropsychological effects of HIIT on breast cancer patients undergoing anthracycline-based chemotherapy. The intervention group (n = 17) will receive a HIIT protocol concurrent with chemotherapy treatment. There will also be a control group (n= 17) to compare the effects of the intervention. Breast cancer survivorship is often ridden with various health and mental problems, the implementation of HIIT procedures could help to reduce these issues. It is expected that knowledge from this study will be useful in the healthcare setting to benefit breast cancer patients. This study will uniquely add to the limited research base by introducing an intervention for neuropsychological declines in breast cancer patients.
determination of mammalian protein function. A CNS specific protein, dCORL is a
member of the Sno/Ski family. Sno acts as a switch between Dpp/dActivin signaling.
dCORL is involved in Dpp and dActivin signaling, but the two homologous mCORL
protein functions are unknown. Conducting transgenic experiments in the adult wings,
and third instar larval brains using mCORL1, mCORL2 and dCORL are used to provide
insight into the function of these proteins. These experiments show mCORL1 has a
different function from mCORL2 and dCORL when expressed in Drosophila. mCORL2
and dCORL have functional similarities that are likely conserved. Six amino acid
substitutions between mCORL1 and mCORL2/dCORL may be the reason for the
functional difference. The evolutionary implications of this research suggest the
conservation of a switch between Dpp/dActivin signaling that predates the divergence of
arthropods and vertebrates.
