Differentiating The Mechanistic Role And Chemotherapeutic Potential Of Src And Podoplanin In Oncogenic Transformation, Edward P. Retzbach

Graduate School of Biomedical Sciences Theses and Dissertations

There were an estimated 20 million new cancer cases worldwide in 2020, resulting in nearly 1000 deaths per hour [1]. Oral cancer exemplifies the difficulties of treating cancer patients. The first line for oral cancer treatment is surgery and radiation that can lead to patient disfigurement and decreased quality of life in cancer survivors [2-4]. Though there have been many developments in chemotherapy in the last 30 years, the 50% mortality rate associated with oral cancer has not changed [4, 5]. Longitudinal studies that track survival rates in oral cancer patients demonstrate a 3-fold reduction in patient deaths when patients …

Effects Of Vaping Nicotine Vs Traditional Cigarette Smoking On Periodontal Patients, Rachel Pion, Brianna Fontes, Megan Robert, Debra Chalmers

Dental Hygiene Student Research Posters

Vaping is becoming increasingly popular as an attempt to decrease traditional smoking. Chemicals found in cigarettes are known to be harmful to the periodontium. Nicotine, found in both inhalants, is a vasoconstrictor that causes a reduction in the inflammatory response. This leads to less bleeding and gingival crevicular fluid (GCF) flow in those that smoke cigarettes versus those that vape. Due to e-cigarettes new prevalence, additional research is required to understand its long-term effects on periodontitis.

The Luminous Night Of The Soul: The Relationship Between Lucid Dreaming And Spirituality, Tadas Stumbrys

International Journal of Transpersonal Studies

Lucid dreams, in which the dreamers are aware that they are dreaming, can be a source of spiritual and mystical experiences. This empirical study aimed to explore the relationship between lucid dreaming and spirituality, taking into account the role of mystical lucid dream experience, in an online sample of 471 respondents, 95% of whom had lucid dream experience and 65% were frequent lucid dreamers. The findings support the relationship between lucid dreaming and spirituality: spiritual transcendence was positively associated with both lucid dream frequency and mystical lucid dream experiences. Thus having recurrent lucid dreams and mystical experiences in them may …

Going Berserk, Running Amok, And The Extraordinary Capabilities And Invulnerability Of Battle Trance, Jenny Wade

International Journal of Transpersonal Studies

Battle trance, which evolved from instinctive defensive and offensive behaviors for close combat, involves socially transgressive processes like becoming-intense and becoming-animal that produce non-ordinary psychophysical states useful in fighting. Berserkergang (going berserk) is one of the best attested types of battle trance and the latest in a long history of Indo-European ecstatic warrior cults, but the state has been identified cross-culturally in consecrated holy amok warriors and in juramentado. Colonial interpretations for centuries have tended to denigrate such fighting styles, even though they involve discipline, spiritual dedication, and altruistic self-sacrifice, especially by falsely attributing such states to intoxication or insanity. …

Public and Population Health Faculty Publications and Presentations

Women with substance use disorder (SUD) often have experienced adverse childhood experiences (ACEs). The intergenerational nature of ACEs also put their children at risk for experiencing ACEs. However, no research has explored the prevalence of ACEs in children whose mothers have SUD. This study assessed ACE scores in mothers with SUD and their children and compared them with non-SUD participants. Females with SUD were recruited from a treatment center (n = 50) and compared to females without SUD from the same area (n = 50). The ACE scores of the participants and their children were measured as well as sociodemographic …

Untangling The Associations Between Generalized Anxiety And Body Dissatisfaction: The Mediating Effects Of Social Physique Anxiety Among Collegiate Men And Women, Mary Pritchard, Kyle Brasil, Ryon Mcdermott, Anna Holdiman

Psychological Sciences Faculty Publications and Presentations

Researchers disagree on which types of anxiety influence body dissatisfaction and how gender (cisgender men vs. cisgender women) may impact these associations. Specifically, little is known about how generalized anxiety and social physique anxiety combine to predict body dissatisfaction in men and women. The purpose of the present study was to explore a moderated mediation model in which the relationships between generalized anxiety and body dissatisfaction (drive for thinness and drive for muscularity) were mediated by social physique anxiety and moderated by gender. Data from 423 U.S. college students (n = 259 women) were analyzed using multigroup structural equation …

The Effects Of Sleep Disturbances On Patients In The Intensive Care Setting, Bronwyn Schmidt

Nursing | Senior Theses

The objective of this research proposal is to identify short-term and long-term health consequences due to sleep disturbances in patients admitted to intensive care units. When reviewing published literature regarding sleep loss in the intensive care unit (ICU), it was discovered that adult patients admitted to a variety of ICU settings both in the United States and abroad reported disruptions in sleep to be a common complaint and barrier to their recovery. This is due to noises made by bedside alarms such as IV pumps, lights in the unit, and interruptions made by medical staff members to provide time-sensitive care. …

Paediatrics Publications

Background: Procedural sedation and analgesia (PSA) is frequently required to perform closed reductions for fractures and dislocations in children. Intravenous (IV) ketamine is the most commonly used sedative agent for closed reductions. However, as children find IV insertion a distressing and painful procedure, there is need to identify a feasible alternative route of administration. There is evidence that a combination of dexmedetomidine and ketamine (ketodex), administered intranasally (IN), could provide adequate sedation for closed reductions while avoiding the need for IV insertion. However, there is uncertainty about the optimal combination dose for the two agents and whether it can provide …

Enacting Contextually Responsive Scholarship: Centring Occupation In Participatory Action Research With Children In India, Tanya Elizabeth Benjamin-Thomas, Debbie Laliberte Rudman, David Mark Thomas

Occupational Therapy Publications

Occupation-based scholars are striving to mobilize socially responsive scholarship to address occupational injustices from local to global scales. Moving forward involves expanding beyond Western, Anglophonic, female, able-bodied, adult perspectives on occupation, with critically informed participatory methodologies providing one key means to incorporate diverse perspectives on occupation and occupational justice. Drawing upon a participatory action research project with children with disabilities from rural South India, this paper puts forward an understanding of participatory action research as an occupational process (i.e., embodying a variety of occupations) and an occupation-based process (i.e., informed by an occupational lens). We forefront how ‘occupation’ was centered …

Alzheimer’s disease (AD) is a complex and heterogeneous disease that can be affected by various genetic factors. Although the cause of AD is not yet known and there is no treatment to cure this disease, its progression can be delayed. AD has recently been recognized as a brain-specific type of diabetes called type 3 diabetes. Several studies have shown that people with type 2 diabetes (T2D) have a higher risk of developing AD. Therefore, it is important to identify subgroups of patients with AD that may be more likely to be associated with T2D. We here describe a new approach …

Neuroinflammation is associated with Alzheimer’s disease, but the application of cerebrospinal fluid measures of inflammatory proteins may be limited by overlapping pathways and relationships between them. In this work, we measure 15 cerebrospinal proteins related to microglial and T-cell functions, and show them to reproducibly form functionally-related groups within and across diagnostic categories in 382 participants from the Alzheimer’s Disease Neuro-imaging Initiative as well participants from two independent cohorts. We further show higher levels of proteins related to soluble tumor necrosis factor receptor 1 are associated with reduced risk of conversion to dementia in the multi-centered (p = 0.027) and …

Klotho-VS heterozygosity (KL-VShet) is associated with reduced risk of Alzheimer’s disease (AD). However, whether KL-VShet is associated with lower levels of pathologic tau, i.e., the key AD pathology driving neurodegeneration and cognitive decline, is unknown. Here, we assessed the interaction between KL-VShet and levels of beta-amyloid, a key driver of tau pathology, on the levels of PET-assessed neurofibrillary tau in 551 controls and patients across the AD continuum. KL-VShet showed lower cross-sectional and longitudinal increase in tau-PET per unit increase in amyloid-PET when compared to that of non-carriers. This association of KL-VShet on tau-PET was stronger in Klotho mRNA-expressing brain …

Plasma phosphorylated-tau181 (p-tau181) showed the potential for Alzheimer’s diagnosis and prognosis, but its role in detecting cerebral pathologies is unclear. We aimed to evaluate whether it could serve as a marker for Alzheimer’s pathology in the brain. A total of 1189 participants with plasma p-tau181 and PET data of amyloid, tau or FDG PET were included from ADNI. Cross-sectional relationships of plasma p-tau181 with PET biomarkers were tested. Longitudinally, we further investigated whether different p-tau181 levels at baseline predicted different progression of Alzheimer’s pathological changes in the brain. We found plasma p-tau181 significantly correlated with brain amyloid (Spearman ρ = …

We have previously reported long-term changes in the brains of non-concussed varsity rugby players using magnetic resonance spectroscopy (MRS), diffusion tensor imaging (DTI) and functional magnetic imaging (fMRI). Others have reported cognitive deficits in contact sport athletes that have not met the diagnostic criteria for concussion. These results suggest that repetitive mild traumatic brain injuries (rmTBIs) that are not severe enough to meet the diagnostic threshold for concussion, produce long-term consequences. We sought to characterize the neuroimaging, cognitive, pathological and metabolomic changes in a mouse model of rmTBI. Using a closed-skull model of mTBI that when scaled to human leads …
