Magic Medicine, Bruce St. Amour, William B. Dehart

HCA Healthcare Journal of Medicine

Background

A superstition is a belief or practice that is considered irrational, resulting from ignorance, fear of the unknown, trust in magic or chance or a false conception of causation. In medical settings superstitions often arise from attempts to assign causation to events that are either random, or in which all information is not available. In this manuscript, we present a descriptive review of the literature related to superstition in medicine and present the results of our own data; that one’s age is equal to the chance of being admitted from the emergency department.

Goblet Cell Carcinoma Of The Appendix: A Case Report On Goblet Cell Carcinoid, Sheliza Kabani, Aubtin Saedi, Austin Lehr, Lina O'Brien

HCA Healthcare Journal of Medicine

Goblet cell carcinoid of the appendix is a rare neoplasm with histological features of both neuroendocrine and adenocarcinomas. The combination of its aggressive behavior, infrequent occurrence, and variable clinical presentation convolutes the management of this tumor. We report the case of a 75-year-old female presenting with acute appendicitis. A laparoscopic appendectomy was performed. The pathology report showed goblet cell carcinoid at the base of the appendix with involvement of the proximal surgical margins. At her postoperative visit, the patient’s pathology report and options for management were reviewed, and the patient agreed to proceed with a right hemicolectomy 8-10 weeks after …

Covid-19: Race For Vaccine, L. Hayley Burgess, Jason J. Braithwaite, Emily Singleton, Aaron M. Young, Mandelin K. Cooper

HCA Healthcare Journal of Medicine

The world is in the midst of a pandemic from COVID-19, a disease caused by the virus SARS-CoV-2. Despite broad mitigation efforts, new cases continue with 74 million cases and 1.6 million deaths worldwide. Regardless of previous research efforts, there is no commercially available vaccine for any coronavirus. Novel vaccine development has historically taken at least 10 years from discovery to availability with only a 6% market entry probability.

With the global impact, there is an urgency to expedite a vaccine to protect the population. The U.S. government launched Operation Warp Speed with the goal to produce and deliver 300 …

Molecular Mechanism Of Cyanobacteria Circadian Clock Oscillator And Effect Of Co Factors On Its Oscillation, Manpreet Kaur

Dissertations

The circadian rhythms arise as an adaptation to the environmental 24-hour day and night cycle due to Earth's rotation. These rhythms prepare organisms to align their internal biological activities and day to day behavior or events with the environmental change of the 24-hour day and night cycle. Circadian rhythms are found widely in all living kingdoms of life on Earth. Cyanobacteria are photosynthetic prokaryotes which first used to study these circadian rhythms. Among cyanobacterial species, Synechococcus elongatus PCC 7942 (henceforth, S. Elongatus) is the simplest organism with a durable and sturdy circadian clock and is study as a model organism. …

Development Of Novel Inks And Approaches For Printing Tissues And Organs, Shen Ji

Dissertations

Tissue engineering is a multidisciplinary field that investigates and develops new methods to repair, regenerate and replace damaged tissues and organs, or to develop biomaterial platforms as in vitro models. Tissue engineering approaches require the fabrication of scaffolds using biomaterials or fabrication of living tissues using cells. As the demands of customized, implantable tissue/organs are increasing and becoming more urgent, conventional scaffold fabrication approaches are difficult to meet the requirements, especially for complex large-scale tissue fabrication. In this regard, three-dimensional (3D) printing attracted more interest over the past decades due to its unrivaled ability to fabricate highly customized tissues or …

Experiments And Modeling Of The Chemo-Mechanically Coupled Behavior Of Polymeric Gels, Nikola Bosnjak

Dissertations

Polymeric materials consist of mutually entangled or chemically crosslinked long njitmolecular chains which form a polymer network. Due to their molecular structure, the njitpolymeric materials are known to undergo large deformation in response to various njitenvironmental stimuli, such as temperature, chemical potential and light.

When a polymer network is exposed to a suitable chemical solvent, the solvent molecules are able to diffuse inside the network, causing it to undergo a large volumetric deformation, known as swelling. In addition to volumetric deformation, this process involves the chemical mixing of the polymer network and solvent molecules, and is typically environmentally responsive. A …

Characterizing Reactive Iron Mineral Coatings And Their Roles In Natural Attenuation At A Site With Historical Contamination, Han Hua

Dissertations

Reactive iron mineral coatings in redox transition zones play an important role in contaminant attenuation. These mineral coatings include poorly crystalline to crystalline iron sulfides, carbonates, and oxyhydroxides, and are a signature of the biogeochemical processes occurring. To better understand these processes, reactive iron mineral coatings are characterized in an 18-m Anaerobic Core collected from a contaminated industrial site. This study targets redox transition zones uncovered in the core. A suite of complementary analyses is applied to distinguish the surface coating mineralogy using X-ray Diffraction, X-ray fluorescence, and field-emission scanning electron microscopy (FESEM) with energy dispersive X-ray analyzer (EDX). In …

Blaming The Victim: Representation The Victim Of Rape In M.F.A Film, Titik Indriyana, Choirul Ulil Albab

Informasi

The media in representing rape victims is still gender biased, such as blaming the victim. This study aims to find out how female victims of rape are shown in the M.F.A film by using semiotics to analyze the structure and ideology contained in the text. The theory used by researchers to analyze texts (M.F.A.) is the concept of radical feminism. The results of the research show in the M.F.A. film, women are shown as sexual objects of men. Women are represented as having to accept anything, including their fate when raped by men. They are not given the strength to …

Blast Shock-Wave Characterization In Experimental Shock Tubes, Sudeepto Kahali

Dissertations

Blast-induced traumatic brain injuries have affected U.S. soldiers deployed for extended periods in the gulf and Afghanistan wars. To identify the biomechanical and biochemical mechanisms of injury, critical in the identification of diagnostic and therapeutic tools, compressed gas-driven shock tubes are used by investigators to study shockwave-animal specimen interactions and its biological consequences. However, shock tubes are designed and operated in a variety of geometry with a range of process parameters, and the quality of shock wave characteristics relevant to field conditions and therefore the study of blast-induced traumatic brain injuries suffered by soldiers is affected by those conditions.
