Associations Between Grit, Life Satisfaction, And Academic Outcomes In Elementary And Middle School Students, Charles Jaylon Williams
Associations Between Grit, Life Satisfaction, And Academic Outcomes In Elementary And Middle School Students, Charles Jaylon Williams
All ETDs from UAB
Grit is used to predict various positive benefits within students. Grit is trying to get back up to attempt another try at one’s goal after failure. Recently, grit has been seen as a potential candidate in improving the life satisfaction and academic performance of individuals. Grit is conceptualized as having two components, perseverance of effort and consistency of interest. Perseverance of effort is trying again until you finally accomplish your goal, while consistency of interest is a constant drive to complete one’s goals over a long-time span. This study measured the effects that grit has on elementary and middle school …

Neuropeptide Y (NPY), a 36-amino acid peptide, has been found to be the most abundant neuropeptide in the central nervous system, and it is widespread across mammalian species. NPY plays a dual role as a neurotransmitter and neuromodulator in the nervous system. NPY functions as a multifaceted neuromodulator through binding NPY receptors (NPYRs). NYP interacts with NPYRs and regulates various activities, such as cell growth, neurogenesis, neuroprotection, mitochondrial behaviors, food intake, anxiety, and addiction formation. In terms of NPY’s neuroprotective potential, NPY inhibits neuronal death signaling, thus preventing apoptosis, and displays anti-inflammatory and anti-oxidative effects. Additionally, it influences metabolism by …

The differentiation of mesenchymal stem cells to pre-osteoblasts, lies upon various transcription factors and physiological signaling, but is also governed by the micro-RNA-23a cluster. The miR-23a cluster has miR-23a, miR-27a and miR-24-2 transcribed from a single promoter as a sole RNA primary transcript. Its effects have been observed in embryonic stem cells, mesenchymal stem cells (MSCs), and in cancer (1-2). It regulates the lineage commitment of MSCs. (3). With respect to bone formation, miR-23a cluster is involved MSCs commitment to and osteoblast maturation (4). Here, through in vivo and in vitro experiments, we report that knock down of microRNA-23a cluster …
A Novel In Vitro Model To Study Immune Interactions In Glioblastoma, Hasan Alrefai
A Novel In Vitro Model To Study Immune Interactions In Glioblastoma, Hasan Alrefai
All ETDs from UAB
Glioblastoma (GBM) is the most common and lethal primary brain tumor in adults. Despite decades of research, GBM has a median survival of approximately 14 months, necessitating the development of novel GBM therapeutics. The drug-development process has been hindered due to the lack of high-fidelity pre-clinical models. While in-vitro models of patient-derived xenografts (PDX) present an interesting approach to modeling GBM, they typically fail to incorporate the non-cancerous cells that support tumor growth and progression. Others have attempted to address this problem by using techniques such as 3D bioprinting to incorporate astrocytes and macrophages in an extracellular matrix; however, they …
Pathophysiology Of Dyt1 Dystonia: Targeted Mouse Models, Chad Christopher Cheetham
Pathophysiology Of Dyt1 Dystonia: Targeted Mouse Models, Chad Christopher Cheetham
All ETDs from UAB
DYT1 dystonia is an inherited movement disorder caused by a trinucleotide deletion (DeltaGAG) in the DYT1 (TOR1A) gene, which codes for the torsinA protein. Dr. Yuqing Li's laboratory previously reported the characterization of a DYT1 dystonia mouse model, a knock-in carrying DeltaGAG in Dyt1 (KI), which displays a motor learning deficit of motor skill transfer. We report here that this motor learning deficit was reversed with an anticholinergic drug, trihexyphenidyl (THP), a drug commonly used to treat movement problems in dystonia patients. We further show a potential substrate for the pathophysiology, a reduction in D2 receptors in the striatum in …
Pediatric Obesity And Traumatic Lower Extremity Long Bone Fracture Outcomes, Ian Charles Backstrom
Pediatric Obesity And Traumatic Lower Extremity Long Bone Fracture Outcomes, Ian Charles Backstrom
All ETDs from UAB
Background: Pediatric obesity is associated with lower extremity injuries and poor outcomes after blunt trauma. Our aim was to determine if obese pediatric patients with femur and tibia fractures have more severe injury patterns and worse outcomes compared to non-obese patients. Methods: We performed a retrospective cohort study of obese and non-obese pediatric patients with femur or tibia fractures treated at two Level-1 trauma centers from 2004-2010. Patients weighing ≥ 95th percentile for age and gender were classified as obese. Patients were compared regarding demographics, Injury Severity Score (ISS), intra-abdominal, and orthopedic injuries. Outcomes included fracture treatment, orthopedic complications, ICU …
