The Perceived Demands Of Crossfit, Bryanne N. Bellovary

All NMU Master's Theses

Rhabdomyolysis is the breakdown of muscle tissue causing myoglobin, creatine kinase, and other intracellular proteins and electrolytes to leak into circulation, disrupting cell homeostasis. Exertional rhabdomyolysis (ER) occurs after extremely rigorous physical training that could include high amounts of strenuous eccentric exercise. There has been an increase in reports for mild to severe ER as well as other musculoskeletal injuries as the popularity of extreme conditioning programs (e.g., CrossFit®) increases. Therefore, the main purposes of this investigation were to identify: primary risk factors associated with ER during CrossFit®, CrossFit® workouts that might induce a higher risk for the development of …

Quantitative Assessment Of Supraorbital Osseous Bar Stability And Symmetry After Frontal Orbital Advancement For Unilateral Coronal Craniosynostosis, Aaron Hart, Chia-Chi Teng, Dr. Richard Hopper, Dr. David Khechoyan, Dr. Jennifer Brown

Journal of Undergraduate Research

Abstract— Frontal-orbital advancement is the accepted surgical treatment for correcting the cranial deformity associated with premature fusion of one of the coronal cranial sutures. Removal and reshaping of the brow and lower forehead bone is performed to correct ipsilateral frontal flattening and parietal bulging, recession of the supraorbital rim, and contralateral forehead bossing. In addition to the functional aspects of the treatment, bilateral symmetry is one desirable outcome that is difficult to achieve because of the recessive movement and shape changes of the supraorbital rim that continue to occur over a prolonged period of time after the operation. Surgeons often …

Role Of Α6 Nachrs In Ethanol Modulation Of Vta Neurons, Samuel Injae Shin

Theses and Dissertations

The prevailing view is that enhancement of dopamine (DA) transmission in the mesolimbic system leads to the rewarding properties of alcohol and nicotine (NIC). The mesolimbic DA system consists of DA neurons in the midbrain ventral tegmental area (VTA) that innervate the nucleus accumbens (NAc). DA neurotransmission is regulated by inhibitory VTA GABA neurons, whose excitability is a net effect of glutamate (GLU) and GABA neurotransmission that are modulated by NIC cholinergic receptors (nAChRs) on afferent terminals. We have previously demonstrated that VTA GABA neurons are excited by low-dose ethanol but are inhibited by moderate to high-dose ethanol, and they …

Different Expression Of Placental Pyruvate Kinase M2 In Normal, Preeclamptic, And Intrauterine Growth Restriction Pregnancies, Brigham L. Bahr

Theses and Dissertations

This thesis will be organized into two chapters discussing the placental expression of two proteins, pyruvate kinase M2 (PKM2) and heat shock protein 27 (HSP 27), in human placentas. Understanding the mechanisms of placental metabolism in healthy and diseased placentas helps us understand how placenta disorders occur and how we can treat these disorders. The goal is to investigate these proteins to gain an understanding of their roles in placental disorders and help decrease maternal and fetal mortality rates. Chapter one covers the background of pyruvate kinase M2 (PKM2) in cancer and embryonic tissues, and the expression of PKM2 in …

Effect Of Dichloromethane Fraction Of Areca Catechu Nut On Monoamines Associated Behaviors And Tyramine Pressor Sensitivity In Rodents, Shagufta Khan, Ghulam Abbas, Fahad Shabbir Ahmed, Attaur Rahman, Ahsana Dar

Department of Biological & Biomedical Sciences

The current study was aimed at investigating the effect of Areca catechu nut dichloromethane fraction (7 mg/kg) on monoamines (serotonin and dopamine) modulation (5-hydroxytryptophan-induced tremors and phenylethylamine-induced stereotypes) and its interaction with tyramine (cheese effect). The dichloromethane fraction caused pronounced increase in 5-HTP-induced tremors (50%) with negligible PEA-induced stereotypes (20%). Additionally, it did not produce a significant increase in the tyramine pressor effects. These results suggest that the dichloromethane fraction of A. catechu nut primarily elevates serotonin levels (probably via monoamine oxidase A inhibition) and does not induce cheese effect.

The Effects Of Substituting True Protein With Non-Protein Nitrogen In Holstein Dairy Heifers Precision-Fed Different Forage To Concentrate Ratios, Noe Alberto Gomez

Animal Science

Understanding the efficiency and digestibility of dietary nutrients in dairy heifers is essential for minimizing costs and environmental impacts of the dairy industry. The objective of this study was to interpret the effects of manipulating rumen-degradable protein (RDP) in a precision feeding system. Eight Holstein ruminally cannulated heifers (14.6 ± 0.1 mo of age, and 386 ± 9.1 kg of weight) were randomly assigned to 2 forage levels: HC (25% forage) and LC (75% forage) and to a degradable protein sequence [0% degradable protein from urea U, 100% casein C (no urea treatment U0); 33% U, 67% C …

The Effects Of Aging On Skeletal Muscle Ampk Activation And An Analysis Of Chronic Aicar Treatment On The Aging Phenotype, Shalene E. Hardman

Theses and Dissertations

AMP-activated protein kinase (AMPK), a metabolic regulator, acts in opposition to many of the effects of aging and may provide insights into the development of sarcopenia. However, the effect of aging on AMPK activation is unclear. The purpose of this dissertation was to: 1) clarify the controversy concerning the activation of AMPK in response to endurance-like exercise in aged skeletal muscle; 2) address mechanisms for the age-associated alterations in AMPK activation; and 3) address the known benefits of chronic AICAR treatment in aged skeletal muscle. First, to clarify the effect of age on AMPK activation, young adult (YA) (8 mo.) …

Endocannabinoid Biosynthetic Enzyme Mrna: Patterns Of Expression In Hippocampus And Ventral Tegmental Area And Effects On Synaptic Plasticity, Collin Brutch Merrill

Theses and Dissertations

Endocannabinoids (eCBs) are lipophilic signals that are produced by postsynaptic neurons in an activity-dependent manner, and signal in a retrograde fashion to modulate neurotransmitter release. As such, eCBs are highly involved in synaptic plasticity, a process that strengthens or weakens synapses. eCB-mediated synaptic plasticity is involved in many brain processes including learning, short-term memory, and adaptive reward, which are processed in the hippocampus and ventral tegmental area (VTA), respectively. However, the expression of eCB biosynthetic enzyme mRNA within hippocampal and VTA neurons, as well as the relationship between these mRNA species and the occurrence of synaptic plasticity, remains unclear. The …
