Only Women Report Increase In Pain Threshold Following Fatiguing Contractions Of The Upper Extremity, Kathy J. Lemley, Jonathon Senefeld, Sandra K. Hunter, Marie K. Hoeger Bement

Physical Therapy Faculty Research and Publications

Purpose

The perception of pain in response to a noxious stimulus can be markedly reduced following an acute bout of exercise [exercise-induced hypoalgesia (EIH)]. Sex differences in EIH frequently occur after exercise but may be confounded by the sex differences in muscle fatigue. The purpose was to determine if sex differences in pain relief occur after an exercise protocol when muscle fatigue is similar for both young and older men and women.

Methods

Pain perception of 33 men (15 young) and 31 women (19 young) was measured using a pressure pain stimulus on the left index finger before and after …

Rna-Seq Analysis Of Localized Mst1/Stk4 Expression In Prostate Cancer, Damien Ready

Master's Theses (2009 -)

The SKT4-encoded MST1 is a serine-threonine protein kinase and has known associations with many diseases and cancer.MST1 plays a critical component of the Hippo tumor suppressor pathway responsible for limiting cell division and promoting apoptosis.Loss of MST1 function is associated with poor prognostic outcomes for cancers, though the mechanism is not well understood.There is increasing evidence that dysregulation of MST1 can lead to castration-resistant prostate cancer (CRPCa), an aggressive cancer with limited treatment options.To better understand the mechanistic underpinnings of CRPCa progression, C4-2 prostate cancer cells were engineered toexpress MST1 protein directed to a particular subcellular region: membrane, nucleus, or …

Reinforcement Learning, Error-Related Negativity, And Genetic Risk For Alzheimer's Disease, Christina Marie Figueroa

Dissertations (1934 -)

Reinforcement learning (RL) has been widely used as a model of animal and human learning and decision-making. The neural networks underlying RL involve many of the same structures primarily affected by Alzheimer’s disease (AD) such as the hippocampus. Yet, RL and non-invasive evaluation of its neural underpinnings have been underutilized as a framework for understanding disease pathology and its pre-clinical states. This study aimed to provide a novel approach for assessing subtle changes in asymptomatic apolipoprotein-E (APOE) carriers and non-carriers. Electroencephalography was collected from forty APOE genotyped older adults (Male n = 11; Mage = 79.30; Meducation = 14.88 years) …
