An Investigation Of Treatments For The Prevention Of Metabolic Complications For Women Suffering From Polycystic Ovarian Syndrome: Diet, Exercise, Weight Reduction And Herbal Remedies, Brenda Martinez-Puente
Nursing | Senior Theses
The purpose of this research study is to compare the views of traditional versus alternative treatments available to women with Polycystic Ovarian Syndrome (PCOS) suffering from metabolic complications. Alternative treatments include diet, exercise, herbal remedies, or any combination of the three. Pharmacological interventions for the conditions associated with PCOS such as metformin, used to control glucose levels, and clomiphene, used to treat infertility. Through the literature review, articles show herbs and plant products to have similar mechanisms of actions as the pharmacological interventions, but with less side effects. For example, cinnamon was shown to increase insulin sensitivity and pomegranate juice ...

The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl
Senior Theses and Projects
Oxygen levels tend to remain at a steady state concentration in the Earth’s atmosphere, yet in some bodies of water, they can fluctuate and decrease drastically. Many organisms that inhabit the swamps, lakes, streams, and parts of the ocean where this occurs have evolved adaptations to manage this environmental uncertainty and continue normal oxygen consumption. The Lwamunda swamp in Uganda is chronically hypoxic, yet it is home to many species, including the electric fish Petrocephalus degeni. P. degeni are unusual by nature of their immense brain, and the Lwamunda swamp appears ill-suited for maintaining this large, metabolically active organ ...
Mechanisms Of Insulin Resistance Related To White, Beige, And Brown Adipocytes, 2020 University of Massachusetts Medical School
Mechanisms Of Insulin Resistance Related To White, Beige, And Brown Adipocytes, Michael P. Czech
Open Access Articles
BACKGROUND: The diminished glucose lowering effect of insulin in obesity, called "insulin resistance," is associated with glucose intolerance, type 2 diabetes, and other serious maladies. Many publications on this topic have suggested numerous hypotheses on the molecular and cellular disruptions that contribute to the syndrome. However, significant uncertainty remains on the mechanisms of its initiation and long-term maintenance.
SCOPE OF REVIEW: To simplify insulin resistance analysis, this review focuses on the unifying concept that adipose tissue is a central regulator of systemic glucose homeostasis by controlling liver and skeletal muscle metabolism. Key aspects of adipose function related to insulin resistance ...

Insulin resistance is associated with aging in mice and humans. We have previously shown that administration of recombinant GDF11 (rGDF11) to aged mice alters aging phenotypes in the brain, skeletal muscle, and heart. While the closely related protein GDF8 has a role in metabolism, limited data are available on the potential metabolic effects of GDF11 or GDF8 in aging. To determine the metabolic effects of these two ligands, we administered rGDF11 or rGDF8 protein to young or aged mice fed a standard chow diet, short-term high-fat diet (HFD), or long-term HFD. Under nearly all of these diet conditions, administration of ...
Hypercholesterolemia Accelerates The Aging Phenotypes Of Hematopoietic Stem Cells By A Tet1-Dependent Pathway, 2020 University of Massachusetts Medical School
Hypercholesterolemia Accelerates The Aging Phenotypes Of Hematopoietic Stem Cells By A Tet1-Dependent Pathway, Guodong Tie, Jinglian Yan, Lyne Khair, Amanda A. Tutto, Louis M. Messina
Open Access Articles
Hypercholesterolemia accelerates the phenotypes of aging in hematopoietic stem cells (HSCs). As yet, little is known about the underlying mechanism. We found that hypercholesterolemia downregulates Ten eleven translocation 1 (Tet1) in HSCs. The total HSC population was increased, while the long-term (LT) population, side population and reconstitution capacity of HSCs were significantly decreased in Tet1(-/-) mice. Expression of the Tet1 catalytic domain in HSCs effectively restored the LT population and reconstitution capacity of HSCs isolated from Tet1(-/-) mice. While Tet1 deficiency upregulated the expression of p19 and p21 in HSCs by decreasing the H3K27me3 modification, the restoration of Tet1 activity ...
Oral Contraceptives As Possible Acl Injury Prevention Method, 2020 Arcadia University
Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer
Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].
Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey ...
Exploring The Heteromeric Interface Of The 5-Ht2a-Mglu2 Receptor Complex, 2020 Virginia Commonwealth University
Exploring The Heteromeric Interface Of The 5-Ht2a-Mglu2 Receptor Complex, Mohamed Aarif Abdul Kareem
Theses and Dissertations
Schizophrenia is a serious mental disorder characteristic of several neurotransmitters including dopamine, serotonin, and glutamate being in imbalance. Early therapies focused solely on dopamine antagonism and second-generation antipsychotics focused on the dopamine and serotonin systems and their respective G protein coupled receptor (GPCR) proteins. Although debate for dimerization of certain classes of GPCR exist, the establishment of an mGlu2-5-HT2A heterocomplex, which is implicated in schizophrenia is of interest. Previous studies have used a mutation-based approach to identify transmembrane domain 4 (TM4) as the domain responsible in mGlu2 for mediating heteromerization before narrowing down the individual amino acids responsible for ...
Biomarkers Of Inflammation In Heart Failure Patients With Reduced And Preserved Ejection Fractions: Multi-Ethnic Study Of Atherosclerosis, Michelle Lynne Stone
UNF Graduate Theses and Dissertations
Purpose Examine the relationships between high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and soluble tumor necrosis factor-α receptor-1 (sTNF-R1) and the cumulative risk of heart failure with reduced (HFrEF) and preserved (HFpEF) ejection fractions in a diverse, population-based sample. Methods Study sample included 6,814 adult (45-84 years of age) men and women who participated in the Multi-Ethnic Study of Atherosclerosis and were free of cardiovascular disease at baseline. Cox regression was used to calculate the hazard ratios (HR) associated with elevated baseline hs-CRP (> 3-10 mg/L), IL-6 (> 75th percentile) and sTNF-R1 (> 75th percentile) and risk of overall HF ...

Coordination Of Airway Protective Behaviors And Swallow: Effects Of Afferent Feedback And Sex., 2019 University of Louisville
Coordination Of Airway Protective Behaviors And Swallow: Effects Of Afferent Feedback And Sex., Alyssa D. Huff
Electronic Theses and Dissertations
This dissertation represents a series of studies describing mechanisms related to breathing, upper airway behaviors and their coordination in man and animal. Chapter two transformed the cough swallow aspiration protocol from the cat (previous work) to the human introducing a new strategy, volume targeting, in swallow breathing coordination. Chapter three evaluated swallow breathing coordination at increasing altitudes. As respiratory drive altered due to hypoxia and hypocapnia, swallow breathing coordination shifted toward inspiration occurring during the transition from inspiration and expiration. The collection of the two previous studies led to development of an animal model to evaluate volume targeting and mechanisms ...
Non-Equilibrium Critical Dynamics Of Bursts In Theta And Delta Rhythms As Fundamental Characteristic Of Sleep And Wake Micro-Architecture, Jilin W. J. L. Wang, Fabrizio Lombardi, Xiyun Zhang, Christelle Anaclet, Plamen Ch. Ivanov
Open Access Articles
Origin and functions of intermittent transitions among sleep stages, including short awakenings and arousals, constitute a challenge to the current homeostatic framework for sleep regulation, focusing on factors modulating sleep over large time scales. Here we propose that the complex micro-architecture characterizing the sleep-wake cycle results from an underlying non-equilibrium critical dynamics, bridging collective behaviors across spatio-temporal scales. We investigate theta and delta wave dynamics in control rats and in rats with lesions of sleep-promoting neurons in the parafacial zone. We demonstrate that intermittent bursts in theta and delta rhythms exhibit a complex temporal organization, with long-range power-law correlations and ...

Aging usually involves the progressive development of certain illnesses, including diabetes and obesity. Due to incapacity to form new white adipocytes, adipose expansion in aged mice primarily depends on adipocyte hypertrophy, which induces metabolic dysfunction. On the other hand, brown adipose tissue burns fatty acids, preventing ectopic lipid accumulation and metabolic diseases. However, the capacity of brown/beige adipogenesis declines inevitably during the aging process. Previously, we reported that DNA demethylation in the Prdm16 promoter is required for beige adipogenesis. DNA methylation is mediated by ten-eleven family proteins (TET) using alpha-ketoglutarate (AKG) as a cofactor. Here, we demonstrated that the ...

Epicardial adipose tissue (EAT) is the visceral fat depot of the heart. Inflammation of EAT is thought to contribute to coronary artery disease (CAD). Therefore, we hypothesized that the EAT of patients with CAD would have increased inflammatory gene expression compared with controls without CAD. Cardiac surgery patients with (n = 13) or without CAD (n = 13) were consented, and samples of EAT and subcutaneous adipose tissue (SAT) were obtained. Transcriptomic analysis was performed using Affymetrix Human Gene 1.0 ST arrays. Differential expression was defined as a 1.5-fold change (ANOVA P < 0.05). Six hundred ninety-three genes were differentially expressed between SAT and EAT in controls and 805 in cases. Expression of 326 genes was different between EAT of cases and controls; expression of 14 genes was increased in cases, while 312 were increased in controls. Quantitative reverse transcription PCR confirmed that there was no difference in expression of CCL2, CCR2, TNF-alpha, IL-6, IL-8, and PAI1 between groups. Immunohistochemistry showed more macrophages in EAT than SAT, but there was no difference in their number or activation state between groups. In contrast to prior studies, we did not find increased inflammatory gene expression in the EAT of patients with CAD. We conclude that the specific adipose tissue depot, rather than CAD status, is responsible for the majority of differential gene expression.

Obesity-associated type 2 diabetes and accompanying diseases have developed into a leading human health risk across industrialized and developing countries. The complex molecular underpinnings of how lipid overload and lipid metabolites lead to the deregulation of metabolic processes are incompletely understood. We assessed hepatic post-translational alterations in response to treatment of cells with saturated and unsaturated free fatty acids and the consumption of a high-fat diet by mice. These data revealed widespread tyrosine phosphorylation changes affecting a large number of enzymes involved in metabolic processes as well as canonical receptor-mediated signal transduction networks. Targeting two of the most prominently affected ...
Dysfunctional Stem And Progenitor Cells Impair Fracture Healing With Age, 2019 Marian University - Indianapolis

Successful fracture healing requires the simultaneous regeneration of both the bone and vasculature; mesenchymal stem cells (MSCs) are directed to replace the bone tissue, while endothelial progenitor cells (EPCs) form the new vasculature that supplies blood to the fracture site. In the elderly, the healing process is slowed, partly due to decreased regenerative function of these stem and progenitor cells. MSCs from older individuals are impaired with regard to cell number, proliferative capacity, ability to migrate, and osteochondrogenic differentiation potential. The proliferation, migration and function of EPCs are also compromised with advanced age. Although the reasons for cellular dysfunction with ...

Doctor of Nursing Practice Projects
Despite the ample amount of knowledge and interventions available to keep patients warm in the operating room, the issue of inadvertent perioperative hypothermia continues to be a problem affecting surgical patients. Unfortunately, even a mild degree of hypothermia can increase a patient’s chance for negative outcomes such as surgical site infections, bleeding, and higher risk for mortality. The project involved development of a warming protocol/guideline for a small community hospital. The implementation process consisted of two separate presentations tailored to educate both nursing and anesthesia staff about the importance of warming patients, reimbursement initiatives, and appropriate interventions.
