Detailing The Effects Of Cannabidiol On Exosome Release In Ewing’S Sarcoma, Bennett Hasley

Theses

Ewing’s sarcoma (ES) is a highly aggressive pediatric cancer found within bone that carries a low five-year survival rate within its patients. This is due, in part, to the cancer’s high malignancy properties as well as the development of resistance to the chemotherapies used to combat this cancer. This project aims to determine if cannabidiol (CBD) has an effect on either exosome release or the protein, signal transducer and activator of transcription 3 (STAT3) within ES cells. Exosomes are vesicles that can carry proteins and other signaling molecules which are released by the cell and allow for cell-to-cell communication. Within …

Genetic Analysis Of Hereditary Gingival Fibromatosis Associated Sos1 Missense Variants Of Uncertain Significance In Caenorhabditis Elegans, Himani Patel

Theses

Hereditary gingival fibromatosis (HGF) is a disease that can present as benign overgrowth of gingival tissue in the mouth. The overgrowth can enclose the entire mouth and teeth in severe cases or present itself in a concentrated area. Researchers have identified that mutations in the SOS1 gene can be responsible for HGF. This disease can impair basic functions related to the mouth. Eating, smiling, speaking can all be affected. Additionally, excess inflammation can cause periodontal disease because of the difficulty in maintaining proper oral health. Periodontal disease can lead to severe bone loss which can lead to complete loss of …

New York City’S Health Governance And Activism From The 1950s To The 1970s, Andres Valcarcel

Irritable Bowel Syndrome, Eating Disorders, And Mental Stress Among United Arab Emirates University Students, Maram Braikan Alotaibi

Theses

Irritable Bowel Syndrome (IBS), Eating Disorders (EDs), and mental stress are understudied in the United Arab Emirates (UAE), especially among university students. The objective of this study is to assess the prevalence of IBS, ED, mental stress, their associations, and the determinants of IBS among United Arab Emirates University (UAEU) students. An observational cross-sectional study was conducted via a 48-item online-survey shared with 14,268 undergraduate/graduate students, registered during academic year 2021-2022 in UAEU. Logistic regression models were performed to examine the predictive factors associated with IBS among UAEU students in total and by ED status. Significance was determined at p< 0.05. The prevalence of IBS was 39%, ED 55.9%, and high mental stress 53.2%, and they co-existed in 15.9% of UAEU students. Students who reported consuming trigger-food were 6 times more likely to have IBS than their counterpart [AOR: 5.859; 95% CI: 3.092–11.102, p< 0.001]. Those who reported intakes of relief-food were 4 times more likely to have IBS compared to their counterpart [AOR: 3.881; 95% CI: 1.669 – 9.022, p=0.002]. Students with family history of IBS (FHIBS) were 2.6 times more likely to have IBS than their counterpart [AOR: 2.572; 95% CI: 1.420–4.660, p= 0.002]. Students with high mental stress were 1.7 times more likely to have IBS than those with low-moderate stress, when adjusted for sex and age [AOR:1.730; 1.058–2.830, p= 0.029). No significant associations existed between IBS and ED, Socioeconomic Characteristics (SEC), lifestyle, dietary, and health-related factors. UAEU students reported high prevalence of IBS, ED and mental stress. A significant relationship was found between IBS and FH-IBS, trigger- and relieving- food. This study confirmed the prevalence of IBS, ED and mental stress. Large cohort studies on university students in the UAE are warranted to establish the relationships among IBS, ED, mental stress and their determinants.

The two members of this family that are the main focus of this thesis are CYP2C19 and CYP2D6. They play major roles in the metabolism of numerous medications, and it is therefore imperative that variations within those genes in various …

Intrinsic Programmed Death Ligand 1 (Pd-L1) Role In Promoting Triple Negative Breast Cancer (Tnbc) Progression, Duaa Salem Alkaabi

Theses

This thesis is concerned with Triple Negative Breast Cancer (TNBC), which is characterized by lack of estrogen, progesterone, and HER2 receptors expression, making targeted drugs ineffective. TNBC has a high proliferative rate, which results in a poor prognosis. Chemotherapy, the primary treatment for metastatic breast cancer, is not an ideal choice due to its toxicity towards normal cells. Therefore, Cancer-targeted therapy has been developed to improve the specificity and strength of the immune system against cancer cells. PD-L1 is an immunosuppressive protein that inactivates T cells by binding to the inhibitory receptor PD-1. The clinical use of PD-L1 blockade agents …

Advances In Upper Gastrointestinal Surgery: Management And Diagnostic Techniques, Gregory L. Falk

Theses

Upper gastrointestinal surgery has progressively moved from the surgically open abdomen to minimally invasive surgery, largely due to technological improvements in instrumentation. A direct result of this Gestalt has been improved patient comfort, rapid recovery and significantly less length of stay in the hospital and therefore significant cost-savings. This was the key impetus to my development of many of the skills in minimally invasive surgery and the subsequent dissemination to other surgeons in an organized and well-recognized teaching system. Many of the novel techniques of this type of surgery led to several publications both in the English and French oncological …

The Impact Of Weighted Football Training On The Skill Acquisition Processes Of Place-Kicking In Sport, Sam Jermyn

Theses

Weighted implement training (WIT) involves performance of sport-specific motor skills with heavier-than-normal sporting implements. Typically, full range of motion (ROM) and similar kinematic characteristics of the respective motor skill are maintained concurrent to minimal changes in the force-velocity movement profile. While the majority of WIT research has been conducted in baseball, track and field, and cricket, there is a paucity of research conducted in the football codes, particularly Gaelic football. Existing observations of increased standard implement velocity and distance following the use of weighted implements infers potential benefits for Gaelic football performance, such as increasing kick-out ball velocity (BV) and …

Residing on opposite sides of the Strait of Messina between Sicily and Calabria, Scylla and Charybdis were mythical sea monsters (one a fearsome creature, the other a deadly whirlpool) described by Homer. For anyone seeking to navigate that narrow and treacherous passage, avoid one of these lethal threats and you would be devoured by the other. For many populations around the world, the conundrum of successfully preventing and/or treating heart failure (HF) to increase longevity, only to increase the probability that it will increase the number of people living with and dying from atrial fibrillation (AF), represents a conundrum of …

Early Movement Matters: Examining The Influence Of Early Postnatal Caregiving Experiences Of Term Infants On Motor And Head Shape Outcomes Across Infancy, Helen E. Beaton

Theses

The nurturing, handling and positioning exposures infants experience during daily caregiving contribute to their physical, motor, cognitive and social–emotional development. A relationship exists between infant sleep and wake-time positioning, the emergence of motor skills and the development of head shape deformities diagnosed as non-synostotic plagiocephaly (NSP). However, the underlying causal mechanism of the specific caregiving behaviours that may play a role remains unclear.

The purpose of the study was to investigate the association between maternal caregiving behaviours and the developmental outcomes of ‘low-risk’ term infants in the first 10 months of life. The first phase of the research involved the …

Detailing The Effects Of Cbd On Parp And Survivin Expression In Ewing Sarcoma, Tyler Carter

Theses

Ewing sarcoma (ES) is an aggressive pediatric bone cancer with low five-year survival rates, particularly with recurrent disease because ES often becomes resistant to chemotherapy in these recurrences. Cannabidiol (CBD) has been identified as a potentially promising therapeutic for patients with ES. In other cancer types, CBD has demonstrated effects on two major proteins that contribute to chemotherapy resistance. The first, Poly (ADP-ribose) Polymerase I (PARP1), is a DNA damage repair enzyme that is overexpressed in recurrent ES. Though chemotherapy induces DNA damage in these cancer cells, the high levels of PARP1 facilitate repair of the DNA, allowing the mutated …
