The human respiratory and circulatory systems collaborate intricately to ensure oxygen delivery to all cells, which is vital for ATP production and maintaining physiological functions and structures. During limited oxygen availability, hypoxia-inducible factors (HIFs) are stabilized and play a fundamental role in maintaining cellular processes for hypoxia adaptation. First discovered during investigations of erythropoietin production regulation, HIFs influence physiological and pathological processes, including development, inflammation, wound healing, and cancer. HIFs promote extracellular adenosine signaling by enhancing adenosine generation and receptor signaling, representing an endogenous feedback mechanism that curbs excessive inflammation, supports injury resolution, and enhances hypoxia tolerance. This is especially …

Faculty, Staff and Student Publications

BACKGROUND: Hospitalisation can be a traumatic experience, where inpatients are exposed to an abundance of physical and psychological stressors. Evidence suggests that these hospital-related stressors negatively impact health: a phenomenon known as post-hospital syndrome. The current study aimed to identify hospital-related stressors, and to develop and provide initial validation for a new measure of in-hospital stress.

METHODS: Measure development occurred in three stages: (i) semi-structured interviews, (ii) item generation, and (iii) pilot testing. Twenty-one patients were interviewed regarding their recent hospital experiences, and a list of hospital-related stressors was produced. These stressors were compiled into a questionnaire and piloted on …

Research outputs 2022 to 2026

Introduction: Brain metastases commonly occur in patients with non-small cell lung cancer (NSCLC). Standard first-line treatment for NSCLC, without an EGFR, ALK or ROS1 mutation, is either chemoimmunotherapy or anti-PD-1 monotherapy. Traditionally, patients with symptomatic or untreated brain metastases were excluded from the pivotal clinical trials that established first-line treatment recommendations. The intracranial effectiveness of these treatment protocols has only recently been elucidated in small-scale prospective trials. Methods: Patients with NSCLC and brain metastases, treated with first-line chemoimmunotherapy or anti-PD-1 monotherapy were selected from the Australian Registry and biObank of thoracic cancers (AURORA) clinical database covering seven institutions. The primary …


Interplay Of Antibody Responses To Closely Related Viruses And Autoimmunity, Chun-Yang Lin Jan 2024

Interplay Of Antibody Responses To Closely Related Viruses And Autoimmunity, Chun-Yang Lin

Theses and Dissertations (ETD)

Antibodies produced by B cells are crucial for eliminating infectious pathogens and preventing secondary infection. However, antibodies may also bind to self-antigens and contribute to autoimmune disease. While pathogen infections have been associated with development of autoimmune diseases, the precise contributions of viral infections to autoimmunity remain elusive. The presence of autoreactive antibodies is associated with an increased risk of developing autoimmune disease. Thus, analyzing the impact of viral infection and vaccination on the development of autoreactive antibodies will provide essential insight into mechanisms that contribute to autoimmune disease.


Examining How Non-Antifungal Medications Impact Host-Fungal Interactions, Parker Ryan Reitler Jan 2024

Examining How Non-Antifungal Medications Impact Host-Fungal Interactions, Parker Ryan Reitler

Theses and Dissertations (ETD)

Invasive fungal infections (IFIs) are estimated to kill 1.5 million people each year with mortality rates remaining high (around 30-70%), despite the availability of three major classes of antifungal drugs. Furthermore, millions more suffer debilitating infections of the mucosal membranes or destructive subcutaneous mycoses. One of the most common IFIs is invasive candidiasis, mostly commonly caused by Candida albicans infections, with mortality rates of approximately 30%. In addition, the population of susceptible individuals and the incidences of both mucosal and systemic mycoses continue to rise due to the widespread use of broad-spectrum antibacterial agents, cancer chemotherapies, and the immune suppressive …


Molecular Determinants Of Trp Channel Gating, Briar J. Bell Jan 2024

Molecular Determinants Of Trp Channel Gating, Briar J. Bell

Theses and Dissertations (ETD)

Transient Receptor Potential (TRP) ion channels are a family of proteins that contribute to a myriad of physiological functions. They have been extensively studied since their discovery 35 years ago; however, there are still many questions regarding the mechanisms by which they function. This family of proteins is characterized by a generally shared structure: an intracellular N terminus featuring ankyrin repeats, six transmembrane helices including the pore domain, a re-entrant loop and TRP helix, and an intracellular C terminus with varying structure. Each of these regions has been implicated in the regular function of TRPs, while mutations that alter trafficking …


Anatomical And Physiological Characterization Of Striatal Activation Of The Cerebral Cortex, Yuhan Wang Jan 2024

Anatomical And Physiological Characterization Of Striatal Activation Of The Cerebral Cortex, Yuhan Wang

Theses and Dissertations (ETD)

Purpose. The striatum receives excitatory glutamatergic input from nearly all parts of the cerebral cortex, and its output is delivered by direct pathway medium spiny neurons (dMSNs) expressing D1 type dopamine (DA) receptors (D1Rs) and indirect pathway MSNs (iMSNs) expressing D2 DA receptors (D2Rs). Loss of DA results in the imbalance between the activities of dMSNs and iMSNs in Parkinson’s disease (PD), leading to ab-normal interactions between the cerebral cortex and striatum. Thus, understanding the inter-actions between the cortex and striatum is important. The monosynaptic corticostriatal cir-cuit has been extensively studied. In contrast, due to the poly-synaptic nature of the …

Characterizing The Cellular Response To Astrovirus Infection In The Central Nervous System, Amy E. Davis

Theses and Dissertations (ETD)

Central nervous system (CNS) diseases caused by infectious agents pose significant health challenges, often leading to severe neurological dysfunction with high morbidity and mortality rates. Astroviruses (AstVs), traditionally known for causing gastroenteritis, have recently been identified as neuroinvasive pathogens capable of inducing neurological diseases. This study explores the cellular and molecular mechanisms by which AstV, specifically non-classical VA1 and classical HAstV1 genotypes, induce CNS pathology in human neurons and astrocytes. Utilizing primary human neurons and astrocytes from various brain regions, this research investigates the cytotoxic effects, apoptotic pathways, and inflammatory responses triggered by these viruses. This study reveals that VA1 …

Pan-Cancer Genomic Characterization Of Human Papillomavirus Associated Tumors, Jeremiah Ray Holt Jan 2024

Pan-Cancer Genomic Characterization Of Human Papillomavirus Associated Tumors, Jeremiah Ray Holt

Theses and Dissertations (ETD)

Infection with high-risk human papillomavirus (HPV) accounts for nearly all cervical cancers (CESC), a subset of other anogenital squamous cancers, and increasing rates of head and neck squamous cell carcinomas (HNSC), with each cancer type having heterogenous outcomes due to a general lack of personalized care. Large scale genomic analyses have catalogued the somatic alterations occurring frequently among squamous tumor types including HNSC and CESC, but few studies have incorporated a thorough analysis of HPV genomics. High-risk HPVs are double-stranded DNA (dsDNA) viruses capable of integrating their genomes into host chromosomes, a phenomenon known to promote HPV-associated cancer formation. HPV …


Ftsk Regulates The Assembly Of The Division Machinery In The Ftsz-Less Chlamydia Trachomatis, Mckenna Katherine Harpring Jan 2024

Ftsk Regulates The Assembly Of The Division Machinery In The Ftsz-Less Chlamydia Trachomatis, Mckenna Katherine Harpring

Theses and Dissertations (ETD)

In evolving to obligate intracellular dependence, Chlamydia trachomatis serovar L2 (Ct), has eliminated several gene products essential for cell division in most other bacteria, including FtsZ, the central coordinator of divisome assembly. In the absence of FtsZ, we show that divisome assembly in Ct is initiated by FtsK, a chromosomal translocase. Chlamydial FtsK forms discrete foci at the septum and at the base of the progenitor mother cell, and our data indicate that FtsK foci at the base of the mother cell mark the location of nascent divisome complexes that form at the site where a daughter cell will emerge …

Ticagrelor Related Anaphylactic Shock In A Stemi Patient, Lam Man Tat, Ip Man Fai, Mok Toi Meng, Chang Tou, Lam U. Po

Journal of the Hong Kong College of Cardiology

An ST elevation myocardial infarction is life-threatening and requires urgent management. Before coronary intervention, preoperative loading a P2Y12 receptor antagonist is warranted. We present a case in which urgent coronary angiography was performed after given loading dose of Aspirin and Ticagrelor. Two and a half hours after loading Ticagrelor, patient developed hypotension with swollen face and diffuse rash on the trunk. Consideration of the anaphylactic shock, a steroid bolus and an inotropic infusion were administered and patient became hemodynamically stable. The allergic manifestations disappeared a few hours later, Ticagrelor was changed to Clopidogrel to avoid the severe allergic reaction.

The Texas Heart Institute Journal

BACKGROUND: Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is quickly becoming a routine and effective means by which to treat degenerated bioprosthetic valves. A known complication of ViV-TAVI is patient-prosthesis mismatch, which substantially affects survival. Bioprosthetic valve fracture is a method by which to reduce the risk of patient-prosthesis mismatch and post-ViV-TAVI transvalvular gradients. This study sought to determine the safety and efficacy of post-ViV-TAVI bioprosthetic valve fracture.

METHODS: Patients with a history of surgical aortic valve replacement undergoing ViV-TAVI bioprosthetic valve fracture (N = 25) at the corresponding institution from 2015 to 2022 were cataloged for a retrospective analysis. …

The Texas Heart Institute Journal

This article reports the case of a 42-year-old man who presented with a saddle pulmonary embolus complicated by normotensive cardiogenic shock. The patient was first stabilized with venoarterial extracorporeal membrane oxygenation. Then, while the patient was still on extracorporeal membrane oxygenation, thrombectomy with a large-bore catheter device was performed that resulted in a large decrease in pulmonary artery pressures and a clinically significant increase in cardiac index, with rapid clinical improvement. Complete recovery of the patient's cardiopulmonary status has been maintained at intermediate-term follow-up. This treatment strategy should be considered favorably in the treatment of patients presenting with pulmonary embolism …

We present the case of a 60-year-old male, with active smoking and cocaine use disorder, who reported progressive chest pain. Various anatomical and functional cardiac imaging, performed to further evaluate chest pain etiology, revealed changing severity and distribution of left main artery (LMA) stenosis, raising suspicion for vasospasm. Intracoronary nitroglycerin relieved the vasospasm, with resolution of the LMA pseudostenosis. A diagnosis of vasospastic angina (VA) led to starting appropriate medical therapy with lifestyle modification counselling. This case highlights VA, a frequently underdiagnosed etiology of angina pectoris. We discuss when to suspect VA, its appropriate work-up, and management.

International guidelines designed to minimize the risk of complications that can occur when correcting severe hyponatremia have been widely accepted for a decade. On the basis of the results of a recent large retrospective study of patients hospitalized with hyponatremia, it has been suggested that hyponatremia guidelines have gone too far in limiting the rate of rise of the serum sodium concentration; the need for therapeutic caution and frequent monitoring of the serum sodium concentration has been questioned. These assertions are reminiscent of a controversy that began many years ago. After reviewing the history of that controversy, the evidence supporting …

PURPOSE: Improving the treatment of psoriasis is a serious challenge today. Psoriasis is an immune-mediated skin condition affecting 125 million people worldwide. It is commonly treated with cyclosporine-A (CsA) and dithranol (DTH). CsA suppresses the activation of T-cells, immune cells involved in forming psoriatic lesions. Meanwhile, DTH is a potent anti-inflammatory and anti-proliferative drug that effectively reduces the severity of psoriasis symptoms such as redness, scaling, and skin thickness. CsA and DTH belong to BCS class II with limited oral bioavailability. We aim to develop a drug delivery system for topical co-delivery of CsA and DTH, exploring its therapeutic potential. …
