Multilevel Considerations For Youth Attention-Deficit/Hyperactivity Disorder Prognosis And Management: Examining The Relationship Between Health Care Factors And Familial Factors In Families Of Children And Adolescents With Adhd, Carey A. Wheelhouse

Theses & Dissertations

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder impacting up to 10% of U.S. youth, and is associated with several negative social, health, and academic or occupational outcomes. Risk and prognostic factors for ADHD are multifactorial, and the management of youth ADHD is multimodal. Familial environments are one prognostic factor for ADHD, with family resilience being positively associated with youth ADHD prognosis. Researchers exploring multilevel interventions for the management of youth ADHD have proposed health care systems as a setting for interventions targeting family resilience, however little research examines the relationship between health care system factors and family factors in families …

MicroRNA-mediated post-transcriptional regulation of lung alveolar type 2 (AT2) and AT1 cell differentiation remains understudied. Here, we demonstrate that the let-7 miRNA family plays a homeostatic role in AT2 quiescence by preventing the uncontrolled accumulation of AT2 transitional cells and promoting AT1 differentiation. Using mouse and organoid models, we show that genetic ablation of let-7a1/let-7f1/let-7d cluster (let-7afd) in AT2 cells prevents AT1 differentiation and leads to KRT8 transitional cell accumulation in progressive pulmonary fibrosis. Integration of AGO2-eCLIP with RNA-sequencing identified direct let-7 targets within an oncogene feed-forward regulatory network, including BACH1/EZH2/MYC, which drives an aberrant fibrotic cascade. Additional CUT&RUN-sequencing analyses …

Molecular Basis Of Trpv3 Channel Blockade By Intracellular Polyamines, Jingying Zhang, Peng Yuan, Colin G Nichols, Grigory Maksaev

2020-Current year OA Pubs

ThermoTRPV1-4 channels are involved in the regulation of multiple physiological processes, including thermo- and pain perception, thermoregulation, itch, and nociception and therefore tight control of their activity is a critical requirement for correct perception of noxious stimuli and pain. We previously reported a voltage-dependent inhibition of TRPV1-4 channels by intracellular polyamines that could be explained by high affinity spermine binding in, and passage through, the permeation path. Here, using electrophysiology and cryo-electron microscopy, we elucidate molecular details of TRPV3 blockade by endogenous spermine and its analog NASPM. We identify a high-affinity polyamine interaction site at the intracellular side of the …

The Menstrual Cycle And Exercise Performance: A Literature Review, Reagan E. Burchill

Honors Thesis

This literature review will examine the current research investigating the relationship between the female menstrual cycle, exercise performance, and exercise instruction. The menstrual cycle is a physiological series of events that includes specific hormones at each stage. These hormones may play a role in how females recover from exercise. This is particularly significant when considering the hormonal fluctuations across the female menstrual cycle, which influence recovery, injury risk, and exercise performance. This could indicate that the suggestions doctors and exercise trainers present to females may not be as beneficial for their health because the research is not specifically tailored to …

Comparative Study On Nephrin, Transforming Growth Factor-Β And Some Biochemical Markers For Predicting Type 2 Diabetic Nephropathy, Alyaa Kadhim Hliel, Huda Farhan Ahmed, Hiba Abdul-Hussein

Al-Nisour Journal for Medical Sciences

Background: Diabetic Nephropathy (DN), is a microvascular complication of the diabetes mellitus type 1 or 2 and the major reason of end-stage kidney disease, which is distinguished by an increase in urine albumin excretion (microalbuminuria) and/or a decreased glomerular filtration rate (GFR) or both. Microalbuminuria has limited diagnostic role in early-stage diabetic nephropathy, because renal damage usually occurs before proteinuria. Therefore, more sensitive and specific biomarkers are needed for early detection of Diabetic Nephropathy.

Materials and Methods: A case-control study involved 180 participants aged 40-≥70 years, 60 individuals were healthy, and 120 had type 2 DM. The participants were divided …

Understanding mechanisms of resistance to active therapies is crucial for developing more effective treatments. Here, we investigate resistance to anti-EGFR and anti-VEGF plus chemotherapy treatment in colorectal cancer (CRC) patients from the IMblaze370 trial (NCT02788279). While anti-VEGF does not select for secondary mutations, anti-EGFR leads to simultaneous mutations in EGFR and MAPK, but not PI3K pathway genes. Notably, we observe frequent acquired mutations in the EGFR extracellular but not intracellular domain and that patients with higher baseline expression of EGFR-ligands are prone to acquire resistant mutations. This data reveals a ligand-activated EGFR/MAPK-signaling dependency in CRC. We also observe enrichment for …

Faculty, Staff and Student Publications

Lewy Body Disease (LBD) and Multiple System Atrophy (MSA) are synucleinopathies with distinct prognoses and neuropathologies, however, with overlapping clinical symptoms. Different disease characteristics are proposed to be determined by distinct conformations of alpha-synuclein (α-Syn) aggregates, which can self-propagate and spread between cells via a prion-like mechanism. The goal of this study is to investigate whether α-syn aggregates amplified from brain and CSF samples of LBD and MSA patients using the Seed Amplification Assay (SAA) maintain α-Syn seeding properties similar to those of α-syn aggregates derived from patients' brains. To address this, SAA-amplified and un-amplified α-Syn aggregates from LBD and …

Biomarkers That Could Explain Parasite-Induced Behavioral Alterations In The Golden Shiner (Notemigonus Crysoleucas) – Posthodiplostomum System, Laura D. Nicolas May 2025

Biomarkers That Could Explain Parasite-Induced Behavioral Alterations In The Golden Shiner (Notemigonus Crysoleucas) – Posthodiplostomum System, Laura D. Nicolas

All HCAS Student Capstones, Theses, and Dissertations

Trophically transmitted parasites require an intermediate host to be consumed and often manipulate host phenotype (i.e., morphology, physiology, and/or behavior) to increase predation risk by definitive hosts. Posthodiplostomum is a trematode with a complex life cycle involving snails as first hosts, fish as second intermediate hosts, and piscivorous birds as definitive hosts. In fish hosts, Posthodiplostomum infection has been linked to increased predation, suggesting suppression of antipredator behaviors. However, the specific physiological pathways remained unexplored and changes in the host’s neural, endocrine, and immune systems could be involved. Thus, I examined whether Posthodiplostomum infection intensity was associated with brain serotonin …

Primary cilia are hair-like structured cell organelles functioning as cellular antennae with chemosensory and mechanosensory roles. Dysfunction of cilia results in ciliopathies, including renovascular diseases (polycystic kidneys, hypertension, aneurysm), mental impedances (Alzheimer's disease, Parkinson's disease, dementia), metabolic diseases (obesity, developmental skeleton defects), blindness, and so on. With a diameter of 150 nm, cilia can be cleaved, released and circulated in the body as injury biomarkers. We here assessed the potential use of isolated cilia as a novel delivery vehicle. Cilia were isolated from renal epithelial cells, and a specific-targeting chemotherapeutic was designed on the cilia. The data show a remarkable …
