The Effects Of Interleukin-1Β On Cardiac Reserve And Exercise Capacity In The Mouse, Habeebah Z. Vohra Jan 2021

The Effects Of Interleukin-1Β On Cardiac Reserve And Exercise Capacity In The Mouse, Habeebah Z. Vohra

Theses and Dissertations

Heart failure (HF) is characterized by dyspnea, fatigue, and exercise intolerance. Clinical evidence points to increased interleukin-1β (IL-1β) activity in patients with HF, with an IL-1 blockade improving the exercise capacity in HF patients. In healthy mice, recombinant-mouse IL-1β (rmIL-1β) induces acute systolic dysfunction, peaking 4 hours after administration. However, the direct effects of rmIL-1β on exercise capacity are unknown. We hypothesized that rmIL-1β diminishes the exercise capacity in the mouse. Adult mice were trained to run on a treadmill and exercise capacity was assessed before, 4 hours, and 96 hours after intraperitoneal administration of rmIL-1β (3 μg/kg) or vehicle …

Characterizing The Physiology And Genetics Of Contact Dependent Growth Inhibiton Systems In Burkholderia Species, Alice Elizabeth Oates Jan 2021

Characterizing The Physiology And Genetics Of Contact Dependent Growth Inhibiton Systems In Burkholderia Species, Alice Elizabeth Oates

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Contact-dependent growth inhibition (CDI) systems mediate interbacterial competition. The genes encoding these systems are widespread among Gram-negative bacteria, including Burkholderia pathogens. CDI systems of Burkholderia species are composed of two-partner secretion pathway proteins and function to deliver the toxic C-terminus of a polymorphic surface-exposed exoprotein BcpA (Burkholderia CDI protein A) to the cytoplasm of neighboring recipient bacteria upon cell-cell contact. Specific outer and inner membrane proteins facilitate BcpA translocation both out of the donor bacterium and into the recipient cell cytoplasm. Most Burkholderia species-specific CDI translocation factors in recipient cells are unknown. BcpA intoxication functions as a mechanism by …

Potential Perioperative Complications Due To Differences in Timing Of Systemic Heparin Distribution During Ruptured Aneurysm Coiling

Introduction:

In general, systematic heparin anticoagulation is standard in regards to neurovascular intervention. When coiling ruptured aneurysms, many neurointerventionalists have their own protocol as to timing of systemic heparinization. There is ample research and literature reviewing the frequency of perioperative events, predictors and outcomes, as well as the efficacy in the use of anticoagulants and/or antiplatelets before, during, and after neurovascular procedures to prevent adverse outcomes. However, there currently exists a dearth of research in regards to timing of distribution of heparin intraoperatively and …

Identification Of Infant Feeding Practices In Eastern Kentucky And Southern West Virginia That Correlate With High Weight-For-Length, Havilah R. Adkins Jan 2021

Identification Of Infant Feeding Practices In Eastern Kentucky And Southern West Virginia That Correlate With High Weight-For-Length, Havilah R. Adkins

DNP Projects

Background: Approximately 20% of children in the United States are obese. West Virginia and Kentucky rank in the top 10 for obesity rates in children as young as 2-4 years old. Obesity increases the risk for numerous short-term health problems and impacts long-term health, development, quality of life, and life expectancy. Research indicates that obesogenic behaviors can be addressed prior to the development of obesity or significant health problems to prevent, rather than treat. Interventions targeting caregivers of infants younger than 2-years can promote early development of healthy feeding habits that persist through the developmental stages of nutrition. Before a …


The Intellectual Property Of Covid-19, Ana Santos Rutschman Jan 2021

The Intellectual Property Of Covid-19, Ana Santos Rutschman

All Faculty Scholarship

The response to COVID-19 is indissolubly tied to intellectual property. In an increasingly globalized world in which infectious disease pathogens travel faster and wider than before, the development of vaccines, treatments and other forms of medical technology has become an integral part of public health preparedness and response frameworks. The development of these technologies, and to a certain extent the allocation and distribution of resulting outputs, is informed by intellectual property regimes. These regimes influence the commitment of R&D resources, shape scientific collaborations and, in some cases, may condition the widespread availability of emerging technologies. As seen throughout this chapter, …


Covid-19 Employee Health Checks, Remote Work, And Disability Law, Elizabeth Pendo Jan 2021

Covid-19 Employee Health Checks, Remote Work, And Disability Law, Elizabeth Pendo

All Faculty Scholarship

The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities, about 61 million individuals in the U.S. The law’s protections in the workplace are especially important during COVID-19, which has worsened pre-existing disparities experienced by people with disabilities. The ADA also applies to new strategies to reduce the risk of COVID-19 infection in the workplace. This Chapter will focus on two strategies that impact individuals with and without disabilities – employee health screening, testing and vaccination policies, and new or expanded remote work programs.

Left ventricular systolic dysfunction (LVSD) is common in patients with pre-existing ischemic heart disease (IHD) and myocardial infarction. An untargeted proteomic approach is used to improve the understanding of the molecular mechanisms associated with LVSD and to find out potential proteomic signatures in pericardial fluid. The pericardial fluid of IHD (n = 45) patients was grouped into two categories according to the left ventricular ejection fraction, LVEF ≥45 (n = 33) and LVEF <45 (n = 12), and analyzed by using nano-liquid chromatography–mass spectrometry (nano-LC-MS/MS) technique. The nano-LC-MS/MS analysis resulted in the identification of 709 pericardial fluid (PF) proteins …

Age-related macular degeneration (AMD) is a leading cause of blindness worldwide. Drusen are key contributors to the etiology of AMD and the ability to modulate drusen biogenesis could lead to therapeutic strategies to slow or halt AMD progression. The mechanisms underlying drusen biogenesis, however, remain mostly unknown. Here we demonstrate that under homeostatic conditions extracellular vesicles (EVs) secreted by retinal pigment epithelium (RPE) cells are enriched in proteins associated with mechanisms involved in AMD pathophysiology, including oxidative stress, immune response, inflammation, complement system and drusen composition. Furthermore, we provide first evidence that drusen-associated proteins are released as cargo of extracellular …

Most amyotrophic lateral sclerosis (ALS) cases are considered sporadic, without a known genetic basis, and environmental exposures are thought to play a causal role. To learn more about sporadic ALS etiology, we recruited n = 188 ALS patients from northern New England and Ohio and matched controls 2:1 from the general population of the same regions. Questionnaires evaluated the association between a variety of lifestyle, behavioral (ie, hobbies and activities), and occupational factors and the risk of ALS, including the duration of time between exposure and ALS onset, and exposure frequency. Head trauma was associated with increased ALS risk (adjusted …

The Texas Heart Institute Journal

Del Nido cardioplegic solution (DNC), used chiefly in pediatric patients, rapidly induces prolonged cardiac arrest during cardiac surgery. To determine whether surgical outcomes after coronary artery bypass grafting in a United States military veteran population differed when DNC was used instead of our standard Plegisol cardioplegia, we retrospectively reviewed 155 consecutive operations performed from July 2016 through June 2017. Del Nido cardioplegia was used to induce cardiac arrest in 70 patients, and Plegisol in 85. Compared with the Plegisol group, the DNC group had a shorter mean cardiopulmonary bypass time (96.8 vs 117 min; P48 hours, atrial fibrillation, tracheostomy, reintubation, …

Benign Metastasizing Leiomyoma In The Heart Of A 45-Year-Old Woman, Mohamad Karnib, Isaac Rhea, Robin Elliott, Saneka Chakravarty, Sadeer G Al-Kindi

The Texas Heart Institute Journal

We report a rare case of benign metastasizing leiomyoma in the heart of a 45-year-old woman 2 years after a uterine leiomyoma had been discovered during hysterectomy. Computed tomograms at presentation showed a large mixed cystic mass in the pelvis and bilateral lung nodules suggestive of metastatic disease. A large cardiac mass, attached to the chordae of the tricuspid valve and later shown to be histopathologically consistent with uterine leiomyoma, was successfully resected through a right atriotomy. This case suggests that benign metastasizing leiomyoma should be considered in the differential diagnosis of right-sided cardiac tumors.


Impact Of 17-Beta Estradiol And Moderate-Intensity Exercise On Mesenteric Arterial Function Of Uc Davis Type-2 Diabetes Mellitus Rats, Md Rahatullah Razan Jan 2021

Impact Of 17-Beta Estradiol And Moderate-Intensity Exercise On Mesenteric Arterial Function Of Uc Davis Type-2 Diabetes Mellitus Rats, Md Rahatullah Razan

University of the Pacific Theses and Dissertations

The studies in this dissertation were designed to investigate the impacts of estrogen (17-β estradiol/E2) and moderate-intensity exercise (MIE) on the mesenteric arterial (MA) function of the University of California Davis type-2 diabetes mellitus (UCD-T2DM) Rat model. Our recent report suggests that diabetes impairs MA vasorelaxation in both sexes of the UCD-T2DM model. Particularly, we reported that MA from prediabetic male rats showed a greater impairment compared to that in prediabetic females. However, when females become diabetic, they exhibit a greater vascular dysfunction than males. Therefore, the aim of the first study was to investigate whether female sex hormone, specifically …
