The Impact Of Disability: A Comparative Approach To Medical Resource Allocation In Public Health Emergencies, Katie Hanschke, Leslie E. Wolf, Wendy F. Hensel

Faculty Publications By Year

It is a matter of time before the next widespread pandemic or natural disaster hits the United States (U.S.). The international response to the 2009 H1N1 influenza stands as a cautionary tale about how prepared the world is for such an emergency. Although the pandemic fortunately proved to be less severe than initially anticipated, it nevertheless resulted in shortages of medical equipment, overburdened hospitals, and preventable patient deaths, particularly among young people.

A pandemic will inevitably lead to difficult decisions about the allocation of medical resources, such as who will have priority access to ventilators and critical care beds when …

We report two cases of infantile diarrhea due to multidrug-resistant, NDM-1 metallo-beta-lactamase-producing Salmonella enterica serovar Agona from Pakistan. This study alerts toward possible risk of NDM-1 transmission to enteric fever pathogens and encourages microbiologists to consider active screening of carbapenem resistance in nontyphoidal Salmonella isolates.


African American Grandparents Residing In A Nursing Facility: Perceptions Of Influence With Their Grandchildren, Family, And Community, Monica Bester Jan 2015

African American Grandparents Residing In A Nursing Facility: Perceptions Of Influence With Their Grandchildren, Family, And Community, Monica Bester

Wayne State University Theses

African American older adults have historically been identified as vital members of the African American family and community (Hill, 1972; Cox, 2002; Waites, 2008). Unfortunately, research has shown an increasing number of older African Americans are being admitted into nursing facilities (Paul, 2004; Feng et al., 2011). Between the years of 1998-2008, it was projected African Americans living in nursing homes increased by 10.8% (Feng et al., 2011).

This study explores the intergenerational relationships of older African American adults with their grandchildren, family, and community through the lens of Intergenerational Family Systems Theory. By viewing this qualitative study through the …

Rna-Binding Protein Celf1 Controls Marcks Mra Translation In Oral Cancer Cells, Mehul Z. Patel

MUSC Theses and Dissertations

Post-transcriptional gene regulation plays an important role in controlling gene expression patterns in mammalian cells. CUG-binding and Embryonic Lethal vision-type RNA-binding protein 3 (ETR)-like Factor (CELF1), also known as CUGBP1, is a RNA-binding protein involved in post-transcriptional gene regulation through nuclear (alternative splicing) and cytoplasmic (mRNA turnover and translation) mRNA processing events. Primarily, CELF1 is known for its contribution to the development of myotonic dystrophy (DM1). But, published observations from our laboratory and others determined that CELF1 is overexpressed in head and neck squamous cell carcinoma (HNSCC) as well as multiple other cancers. Unpublished proteomic pulsed-stable isotope labeling by amino …

Short-Term Effects On The Fetus And Long-Term Outcome On Children Exposed To Maternal Chemotherapy, Yocheved Kramer Jan 2015

Short-Term Effects On The Fetus And Long-Term Outcome On Children Exposed To Maternal Chemotherapy, Yocheved Kramer

The Science Journal of the Lander College of Arts and Sciences

Ethical questions with regard to treatment arise when pregnant women are diagnosed with cancer. Does the health of the mother or the health of the fetus take priority? However, research suggests that concern over transplacental transfer should not deter those seeking treatments since avoidance of favorable transfer drugs can allow chemotherapy to be a viable option if properly administered. Doctors highly contraindicate the use of chemotherapeutic drugs in the first trimester due to high risks such as teratogenesis and fetal death. However, they reassure that treatment can be given in the final two trimesters. It presents minimal consequences as long …


Understanding The Hygiene Hypothesis And Its Mechanisms, Yaakov Tropper Jan 2015

Understanding The Hygiene Hypothesis And Its Mechanisms, Yaakov Tropper

The Science Journal of the Lander College of Arts and Sciences

The hygiene hypothesis provides an explanation for the sharp increase in atopy over the past several decades by proposing that it is inversely related to the lack of infectious diseases in our society. Although atopy, as well as other hypersensitivity reactions, do have a genetic basis; studies clearly show that environmental and socioeconomic factors play a large role in determining which people will develop allergies. Proposed mechanisms leading to this disorder include an imbalance in the Th1/Th2 complex in the immune system, and a deficiency in Regulatory T cells which controls excessive T cell activity.

Pitch-Count And Its Effects On Shoulder Injuries: How To Keep A Pitcher Healthy, Alexander Malek

The Science Journal of the Lander College of Arts and Sciences

Baseball is currently the fourth most popular sport in high schools across the country. However, pitchers are at a high risk to develop career ending injuries. Overuse can result in SLAP tears as well as torn rotator cuff muscles that can end a dream of pitching professionally. Major League Baseball has teamed up with leading sports medicine researchers to determine safe pitch-count guidelines for pitchers of all ages. Articles were found using Touro’s e-Journal database as well as Pubmed.gov to find pertinent research on this topic. Studies on ball velocity and scapular kinematics were done on three different levels of …


Development Of A Yeast-Based Assay For The Functional Characterization Of Fkbp52/ Î?-Catenin Interactions With The Androgen Receptor, Theresa Anne Rodriguez Jan 2015

Development Of A Yeast-Based Assay For The Functional Characterization Of Fkbp52/ Î?-Catenin Interactions With The Androgen Receptor, Theresa Anne Rodriguez

Open Access Theses & Dissertations

Prostate cancer development is uniquely dependent on the androgen receptorâ??s (ARâ??s) transcriptional regulation in response to hormone binding. Current therapies directly target AR acting as an antagonist at androgen binding sites. However, once androgen-dependence is lost, meaning the patient has progressed into a late-stage hormone resistant phenotype, all current treatments are essentially ineffective. Utilizing the yeast strain Saccharomyces cerevisiae we are capable of creating a model system that allows for the exogenous expression of AR while still retaining the chaperone components needed for this steroid receptor complex. The 52kDa FK506 binding protein (FKBP52) has been shown to be an important …

Methods

Patients 3 to 6 months poststroke underwent a battery of assessments before receiving 3 weeks of standardized upper extremity robotic therapy. Candidate predictors included measures of brain injury (including to gray and white matter), neural function (cortical function and cortical connectivity), and clinical …


Coffee: A Selected Overview Of Beneficial Or Harmful Effects On The Cardiovascular System?, Thomas F. Whayne Jr. Jan 2015

Coffee: A Selected Overview Of Beneficial Or Harmful Effects On The Cardiovascular System?, Thomas F. Whayne Jr.

Internal Medicine Faculty Publications

With a history that began in 800 A.D., coffee is the most popular drink known and as a result, the issues regarding its physiologic effects deserve attention. Maintaining alertness is a well-known benefit and in addition, the cardiovascular (CV) effects of the active compounds, which include polyphenols and caffeine, must be considered. Genetics are relevant and where slow caffeine metabolism is inherent, the risk of nonfatal myocardial (MI) has been shown to be increased. Overall risk for coronary heart disease (CHD) is not supported and unless there is excessive intake, congestive heart failure (CHF) is not adversely affected; in moderation, …

Therapeutic Targeting Of Replicative Immortality, Paul Yaswen, Karen L. Mackenzie, W. Nicol Keith, Patricia Hentosh, Francis Rodier, Jiyue Zhu, Gary L. Firestone, Ander Matheu, Amancio Carnero, Alan Bilsland

School of Medical Diagnostics & Translational Sciences Publications

One of the hallmarks of malignant cell populations is the ability to undergo continuous proliferation. This property allows clonal lineages to acquire sequential aberrations that can fuel increasingly autonomous growth, invasiveness, and therapeutic resistance. Innate cellular mechanisms have evolved to regulate replicative potential as a hedge against malignant progression. When activated in the absence of normal terminal differentiation cues, these mechanisms can result in a state of persistent cytostasis. This state, termed “senescence,” can be triggered by intrinsic cellular processes such as telomere dysfunction and oncogene expression, and by exogenous factors such as DNA damaging agents or oxidative environments. Despite …

Mammary Glands Possess Intrinsic Molecular Laterality And Respond Left-Right Differently To Genetic And Pharmacological Manipulation, Jacqulyne Michelle Ponville-Robichaux Jan 2015

Mammary Glands Possess Intrinsic Molecular Laterality And Respond Left-Right Differently To Genetic And Pharmacological Manipulation, Jacqulyne Michelle Ponville-Robichaux

MUSC Theses and Dissertations

Mammary Glands Possess Intrinsic Molecular Laterality and Respond Left-Right Differently to Genetic and Pharmacological Manipulation. (Under the direction of Ann Ramsdell) More tumors form in the left (L) breast and tumors in the right (R) breast may be more aggressive. These epidemiological findings suggest L-R differences in overall tumor biology depending on the side of tumor origin, leading to the hypothesis that mammary glands are L-R different and have discordant responses to neoplastic risk factors. Here we show that normal mammary glands are molecularly L-R different, and have more mammary stem cells (MaSCs) in the L thoracic mammary gland (TMG). …


Circulating Fibroblast Precursors In Soft Tissue Sarcoma Metastasis, Dayvia Laws Russell Jan 2015

Circulating Fibroblast Precursors In Soft Tissue Sarcoma Metastasis, Dayvia Laws Russell

MUSC Theses and Dissertations

Soft tissue sarcomas (STS) are rare, malignant tumors of mesenchymal origin that manifest in the connective tissues, including muscle, adipose and deep skin tissue, nerves, and joint tissue. Complications from primary or recurrent sarcomas often lead to increased morbidity, but the most lethal aspect of sarcomas is their propensity for hematogenous dissemination leading to metastatic disease. After development of distant metastases, the median survival for patients with STS is merely 11 to 15 months1,2. Therefore, gaining a better understanding of the metastatic environment is essential to developing new therapies. The tumor microenvironment has been implicated as an essential component for …


Clinical And Pathologic Significance Of Integrin Α6Β4 Expression In Human Malignancies, Rachel L. Stewart Jan 2015

Clinical And Pathologic Significance Of Integrin Α6Β4 Expression In Human Malignancies, Rachel L. Stewart

Theses and Dissertations--Clinical and Translational Science

Integrins are cellular adhesion molecules that bind cells to the extracellular matrix. The integrin α6β4, a receptor for laminins, is predominantly expressed on epithelial cells where it is present at the basal surface adjacent to the basement membrane. This integrin plays a critical role in maintaining normal cellular functions, yet has also been implicated in promoting invasion and metastasis in human malignancies. While overexpression of the integrin α6β4 has been detected in select human cancers, the clinical significance of integrin α6β4 expression in a number of malignancies has not been determined. The purpose of this study was to examine integrin …

Research outputs 2014 to 2021

Repeat tumor biopsies to study genomic changes during therapy are difficult, invasive and data are confounded by tumoral heterogeneity. The analysis of circulating tumor DNA (ctDNA) can provide a non-invasive approach to assess prognosis and the genetic evolution of tumors in response to therapy. Mutation-specific droplet digital PCR was used to measure plasma concentrations of oncogenic BRAF and NRAS variants in 48 patients with advanced metastatic melanoma prior to treatment with targeted therapies (vemurafenib, dabrafenib or dabrafenib/trametinib combination) or immunotherapies (ipilimumab, nivolumab or pembrolizumab). Baseline ctDNA levels were evaluated relative to treatment response and progression-free survival (PFS). Tumor-associated ctDNA was …


The Analysis Of Diruthenium Compounds On Human Cells As Potential Chemotherapeutic Agents, Elizabeth Mcculloch Jan 2015

The Analysis Of Diruthenium Compounds On Human Cells As Potential Chemotherapeutic Agents, Elizabeth Mcculloch

Honors Program Theses

Chemotherapy is a common method of cancer treatment, and cisplatin is a common anticancer compound used in chemotherapy. While effective, cisplatin is known to cause many side effects, and people can form resistance to it. Because of these problems, new chemotherapeutic compounds are needed. One compound that has shown anticancer properties, an ability to overcome resistance, and nontoxicity is ruthenium. Multiple mono-ruthenium compounds have been previously studied and were found to be effective. The current research project synthesized a diruthenium compound Cp2Ru2(bipy)2(DMSO)2 and exposed the compound to human liver cells (HepG2) to determine …


Analysis Of Protein Expression For Potential Biomarkers In Human Pancreatic Tumor Cell Lines, Jade Ashley Simpson Jan 2015

Analysis Of Protein Expression For Potential Biomarkers In Human Pancreatic Tumor Cell Lines, Jade Ashley Simpson

Honors Program Theses

Pancreatic cancer is an aggressive cancer of the pancreas that has been shown to have extremely low survival rates. It can be quite lethal because of its asymptomatic early stages and inability to detect cancer at the cellular level. Once diagnosed, the cancer will have usually spread or metastasized beyond surgical resection. Thus, research is focused on finding potential biomarkers in tumor cell lines to help in earlier diagnosis of this disease leading to better treatment options. Previous work using bioinformatics data suggest several cellular genes including, CTHCR1, EPPK1, AHNAK2, and IGHG3, can be potential biomarkers for pancreatic cancer. The …


Targeting The Tight Junction Protein, Zonula Occludens-1, With The Connexin 43 Mimetic Peptide, Αct-1 Reduces Vegf-Dependent Rpe Pathophysiology, Elizabeth Christa Obert Jan 2015

Targeting The Tight Junction Protein, Zonula Occludens-1, With The Connexin 43 Mimetic Peptide, Αct-1 Reduces Vegf-Dependent Rpe Pathophysiology, Elizabeth Christa Obert

MUSC Theses and Dissertations

Age-related macular degeneration (AMD) is a multifactorial disease and is regarded as the predominant cause of central vision loss in the elderly in industrialized countries. A critical target tissue in AMD is the retinal pigment epithelium (RPE), which together with Bruch’s membrane forms the outer blood-retina barrier (BRB). RPE-barrier dysfunction in AMD might result from attenuation and disruption of intercellular tight junctions. Zonula occludens-1 (ZO-1) is a major structural protein of intercellular junctions. A connexin-based peptide mimetic, αCT-1 (Alpha Connexin carboxy-Terminal 1), was developed which competitively inhibits ZO-1 interaction with its binding partners. We hypothesized that targeting ZO-1 signaling using …


Mechanisms Of Mitochondrial Dysfunction In Sepsis-Induced Kidney Injury, Joshua Andrew Smith Jan 2015

Mechanisms Of Mitochondrial Dysfunction In Sepsis-Induced Kidney Injury, Joshua Andrew Smith

MUSC Theses and Dissertations

Mitochondrial dysfunction is a well-characterized pathophysiological feature of acute kidney injury (AKI). Our laboratory has previously implicated suppression of mitochondrial biogenesis, the process by which cells generate new and functional mitochondria, as an important contributor to development of mitochondrial dysfunction in multiple experimental models of AKI. However, relatively little is known about the molecular mechanisms responsible for disruption of biogenesis in renal cells. The primary goals of this project were to define signaling pathways mediating acute suppression of renal cortical mitochondrial biogenesis and to characterize changes in glycolytic metabolism that might support both cellular and organ function following sepsis-induced AKI. …
