Snf1 Dependent Destruction Of Med13 Is Required For Programmed Cell Death Following Oxidative Stress In Yeast, Stephen D Willis, David C Stieg, R. Shah, Randy Strich, Katrina F Cooper Dec 2017

Snf1 Dependent Destruction Of Med13 Is Required For Programmed Cell Death Following Oxidative Stress In Yeast, Stephen D Willis, David C Stieg, R. Shah, Randy Strich, Katrina F Cooper

Rowan-Virtua School of Osteopathic Medicine Departmental Research

All eukaryotic cells, when faced with unfavorable environmental conditions, have to decide whether to mount a survival or cell death response. The conserved cyclin C and its kinase partner Cdk8 play a key role in this decision. Both are members of the Cdk8 kinase module that, along with Med12 and Med13, associate with the core mediator complex of RNA polymerase II. In S. cerevisiae, oxidative stress triggers Med13 destruction1, which thereafter releases cyclin Ci nto the cytoplasm. Cytoplasmic cyclin C associates with mitochondria where it induces hyper-fragmentation and programmed cell death2. This suggests a model in …


Authentic Leadership—Is It More Than Emotional Intelligence?, Phyllis Duncan, Mark Green, Esther Gergen, Wenonah Ecung Dec 2017

Authentic Leadership—Is It More Than Emotional Intelligence?, Phyllis Duncan, Mark Green, Esther Gergen, Wenonah Ecung

Administrative Issues Journal

One of the newest theories to gain widespread interest is authentic leadership. Part of the rationale for developing a model and subsequent instrument to measure authentic leadership was a concern that the more popular theory, the full range model of leadership and its instrument, the Multifactor Leadership Questionnaire (MLQ) (Bass & Avolio, 1985), did not sufficiently emphasize aspects of leader emotional intelligence (EI), such as self-awareness (Avolio & Gardner, 2005).

In its current configuration, the Authentic Leadership Questionnaire (ALQ) (Walumba, Avolio, Gardner, Wernsing & Peterson, 2008) measures four dimensions of leadership: relational transparency, internal moral perspective, balanced processing, and self-awareness. …


Translocation Of Cyclin C During Oxidative Stress Is Regulated By Interactions With Multiple Trafficking Proteins, Daniel G J Smethurst, Katrina F Cooper, Randy Strich Dec 2017

Translocation Of Cyclin C During Oxidative Stress Is Regulated By Interactions With Multiple Trafficking Proteins, Daniel G J Smethurst, Katrina F Cooper, Randy Strich

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Eukaryotic cells take cues from their environment and interpret them to enact a response. External stresses can produce a decision between adjusting to behaviors which promote surviving the stress, or enacting a cell death program. The decision to undergo programmed cell death (PCD) is controlled by a complex interaction between nuclear and mitochondrial signals. The mitochondria are highly dynamic organelles that constantly undergo fission and fusion. However, a dramatic shift in mitochondrial morphology toward fission occurs early in the PCD process. We have identified the transcription factor cyclin C as the biochemical trigger for stress‐induced mitochondrial hyper‐fragmentation in yeast (Cooper …


Mechanistic Insights Into The Regulation Of Mitochondrial Fission By Cyclin C, Vidyaramanan Ganesan, Katrina F Cooper, Randy Strich Dec 2017

Mechanistic Insights Into The Regulation Of Mitochondrial Fission By Cyclin C, Vidyaramanan Ganesan, Katrina F Cooper, Randy Strich

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Cyclin C is a component of the mediator complex of RNA polymerase II that localizes to the nucleus under normal conditions. In response to stress, cyclin C translocates to the cytosol and mitochondria and mediates stress‐induced mitochondrial fission and apoptosis. The molecular mechanisms by which cyclin C induces mitochondrial fission are unknown. Using in vitro experimental approaches, we sought to investigate the mechanistic basis of cyclin C mediated mitochondrial fission.

Inpatient Hospice Home: A Needs Assessment And Business Plan, Stacey Middleton

Doctor of Nursing Practice Scholarly Project

An Abstract of the Scholarly Project by

Stacey Middleton

There are two constants that every person can count on in life, being born and dying. No amount of research is required, and there is no need to challenge the inevitable. When a child is born, people celebrate and congratulate the new parents and their family. When a person dies, people are saddened by the loss of a friend and loved one. Death comes to all and is either, fast and unexpected or a slow drawn out process. Every dying patient deserves to die with dignity, be free from pain, and …


Identification Of Prognostic Cancer Biomarkers Through The Application Of Rna-Seq Technologies And Bioinformatics, Nathan Wong Dec 2017

Identification Of Prognostic Cancer Biomarkers Through The Application Of Rna-Seq Technologies And Bioinformatics, Nathan Wong

McKelvey School of Engineering Graduate Student Theses & Dissertations

MicroRNAs (miRNAs) are short single-stranded RNAs that function as the guide sequence of the post-transcriptional regulatory process known as the RNA-induced silencing complex (RISC), which targets mRNA sequences for degradation through complementary binding to the guide miRNA. Changes in miRNA expression have been reported as correlated with numerous biological processes, including embryonic development, cellular differentiation, and disease manifestation. In the latter case, dysregulation has been observed in response to infection by human papillomavirus (HPV), which has also been established as both oncogenic in cervical cancers and oropharyngeal cancers and favorable for overall patient survival after tumor formation. The identification of …

An Evidence-Based Implementation Project On High Utilizers In The Emergency Department, Bernadette Martin Ruggles

Doctor of Nursing Practice (DNP) Projects

Abstract

Challenges have been presented to the Emergency Department (ED) over the last several years as the dramatic rise in health insurance enrollment continues. Although, with the Republican bill, the American Health Care Act, changes to Medicaid may alter the health program leaving many uncertainties (Kaplan & Pear, 2017). Evidence reflects EDs are inundated with even more patients taking advantage of the availability of a one-stop shop for their care and treatment. Costs of ED services and resource allocation are rising as a result of these unnecessary visits contributing to a total healthcare expenditure of approximately 17.6% of the US …

Leadership Development, Succession Planning And Simulation: A Succession Plan For Organizational Success, Beth Eichenberger Dec 2017

Leadership Development, Succession Planning And Simulation: A Succession Plan For Organizational Success, Beth Eichenberger

Doctor of Nursing Practice (DNP) Projects

Future executive nurse leaders must be identified and prepared for the challenges of 21st century health care. The literature suggests a lack of existing standardized succession plans for these leaders. Senior leaders are often faced with the complex issue of how to develop and validate the competencies required for these leadership roles (Dyess, Sherman, Pratt, & Chiang- Hanisko, 2016). Therefore, in the absence of a succession plan, creating a leadership development program, which provides a pipeline of new executive leaders, would alleviate this gap. The motivating force is an effort to promote current talent and provide a higher level of …

Type 2 Neural Progenitor Cell Activation Drives Reactive Neurogenesis After Binge-Like Alcohol Exposure In Adolescent Male Rats, Chelsea Rhea Geil Nickell, Hui Peng, Dayna M. Hayes, Kevin Y. Chen, Justin A. Mcclain, Kimberly Nixon

Pharmaceutical Sciences Faculty Publications

Excessive alcohol consumption during adolescence remains a significant health concern as alcohol drinking during adolescence increases the likelihood of an alcohol use disorder in adulthood by fourfold. Binge drinking in adolescence is a particular problem as binge-pattern consumption is the biggest predictor of neurodegeneration from alcohol and adolescents are particularly susceptible to the damaging effects of alcohol. The adolescent hippocampus, in particular, is highly susceptible to alcohol-induced structural and functional effects, including volume and neuron loss. However, hippocampal structure and function may recover with abstinence and, like in adults, a reactive burst in hippocampal neurogenesis in abstinence may contribute to …

Float Rns: Unit Specific Tools To Promote A More Positive Float Experience, Tarra Abdullah-Grayson

Doctor of Nursing Practice (DNP) Projects

Despite efforts to transition large portions of primary health care services to more community-based outpatient settings, federal projections say the rising complexity of acute care will increase demand for RNs in hospital settings by 36% in 2020 (American Association of Colleges of Nursing [AACN], 2017). Other projections indicate that by 2025, the U.S. registered nursing shortage will expand to more than 260,000 (Buerhaus, Auerbach, & Staiger, 2009). In an effort to address the ongoing challenges of nursing staff shortages, many hospitals have established a core of internal float pool RNs as a practical and cost effective solution to address the …

Acquisition Of Aquatic Motor Skills Through Children’S Motor Stories, Juan Antonio Moreno Murcia, Elisa Huescar Hernandez, Jose Antonio Richart Parra Dec 2017

Acquisition Of Aquatic Motor Skills Through Children’S Motor Stories, Juan Antonio Moreno Murcia, Elisa Huescar Hernandez, Jose Antonio Richart Parra

International Journal of Aquatic Research and Education

An increasing interest in the renewal of traditional recreational content and the use of the aquatic environments as educational resources is supported by very few empirical, evidence-based studies that link the two. This quasi-experimental study analyzed the role of stories in influencing perceived motor competence and real motor skills in seventy-eight children ages between 4 and 5 years through the administration of two questionnaires on aquatic motor ability and aquatic motor competence. Differences were found in aquatic motor competence (p < .01) and aquatic motor ability (p < .05) for the experimental group, where higher means values were obtained after the intervention. We present this methodological proposal as a useful educational tool for early childhood stimulation with achievements that go beyond motor progress itself.


The Role Of Yes-Associated Protein 1 In Ovarian Physiology And Pathology, Xiangmin Lv Dec 2017

The Role Of Yes-Associated Protein 1 In Ovarian Physiology And Pathology, Xiangmin Lv

Theses & Dissertations

Ovarian granulosa cells are the major somatic components of the ovarian follicle. Proper proliferation and differentiation of ovarian granulosa cells are essential for successful follicle development. Accumulating evidence indicates that the Hippo-YAP signaling pathway plays critical roles in both development and tumorigenesis of several organs. The present study aims to investigate the role of Yes-associated protein 1 (YAP) in ovarian granulosa cell proliferation, differentiation, and malignant transformation. At first, we found that nuclear YAP (active) was highly expressed in proliferative granulosa cells, whereas cytoplasmic YAP (inactive) was detected mainly in terminally-differentiated luteal cells. Further studies suggested that endogenous YAP activity …


Novel Therapeutic Approaches For Juvenile Neuronal Ceroid Lipofuscinosis (Cln3), Megan Elizabeth Bosch Dec 2017

Novel Therapeutic Approaches For Juvenile Neuronal Ceroid Lipofuscinosis (Cln3), Megan Elizabeth Bosch

Theses & Dissertations

Juvenile Neuronal Ceroid Lipofuscinosis (JNCL) is a lysosomal storage disease caused by autosomal recessive mutations in CLN3. Neuronal loss is thought to occur via glutamate excitotoxicity; however, little is known about neuron-astrocyte glutamate regulation in JNCL. We discovered that Cln3Δex7/8 astrocytes have significantly lower basal spontaneous Ca2+ oscillations and decreased responses to glutamate, indicating a disrupted signaling network. Cln3Δex7/8 astrocytes also displayed significantly lower basal mitochondrial respiration and ATP production, suggesting impaired metabolic functions. Concurrent with diminished astrocyte metabolism and Ca2+ signaling, Cln3Δex7/8 neurons were hyper-responsive to glutamate stimulation. These studies suggest that CLN3 …


Evaluation Of Immune-Modulating Therapies For Parkinson's Disease, Katherine E. Olson Dec 2017

Evaluation Of Immune-Modulating Therapies For Parkinson's Disease, Katherine E. Olson

Theses & Dissertations

Parkinson’s disease (PD) is the second most common neurodegenerative

disorder, second only to Alzheimer’s disease (AD). It is characterized by a

progressive loss of dopaminergic neurons along the nigrostriatal axis and the

formation of proteinaceous inclusions of alpha-synuclein (α-syn). Secondary to

the loss of dopaminergic neurons is a progression in motor and non-motor

symptoms. Motor symptoms are characterized by slowness in movement,

stiffness and tremor. Non-motor symptoms include depression, constipation,

sleep abnormalities and loss of sense of smell. The cause of disease remains

incompletely understood. However, age, genetics, environment, viral infection,

and interplay between the innate and adaptive immune system …
