Acute Effects Of Placebo And Open-Label Placebo Treatments On Muscle Strength, Voluntary Activation, And Neuromuscular Fatigue., Alina Swafford

Electronic Theses and Dissertations

Placebo treatments have long been used to study the psychological effects of expectancy and conditioning on an inert intervention. Interestingly, open-label placebo treatments (i.e., directly telling subjects they are receiving an inactive intervention) have recently shown promise in minimizing pain in clinical patient populations. We utilized a repeated measures design to examine the acute effects of placebo, open-label placebo, and control treatments on muscle strength and voluntary activation (Experiment #1), as well as neuromuscular fatigue (Experiment #2). Twenty-one untrained males (n=11) and females (n=10) visited the laboratory on three occasions to receive each treatment in a randomized, counter-balanced manner. All …


Regulation Of Extra-Pituitary Prolactin In Monocytes And Macrophages, Richard Barrett Jan 2018

Regulation Of Extra-Pituitary Prolactin In Monocytes And Macrophages, Richard Barrett

Electronic Theses and Dissertations

Recently it has been shown that leukocytes are capable of producing prolactin (PRL). Evidence of extra-pituitary PRL (ePRL) production is so far been limited to primates and is not shared across other mammal species such as mice and rats. While ePRL is characterized as an identical protein to traditional pituitary PRL, it is controlled under an alternative promoter and is thus regulated differently from pituitary PRL. Little is known about what regulates ePRL or its direct role in human physiology, but given that PRL has well over 300 described functions, it is likely that the autocrine and paracrine effects of …

Pcb-Associated Steatohepatitis And The Role Of Nuclear Receptors., Heather Brooke Clair Dec 2017

Pcb-Associated Steatohepatitis And The Role Of Nuclear Receptors., Heather Brooke Clair

Electronic Theses and Dissertations

Metabolic diseases, including fatty liver disease, hyperglycemia, and obesity, result when body systems responsible for managing allostasis (dynamic homeostasis across systems) are pressured beyond their collective compensatory reserve. Nutritional excess contributes to this state, the capacity of which is limited by genetic variation, and failure of one system will gradually lead to pathological overload in the others. Agents which act directly on the communication machinery linking these connected systems can also change the point at which allostatic load becomes allostatic overload. Environmental exposure to polychlorinated biphenyls (PCBs), a class of persistent organic pollutant, is associated with a specific form of …
