Background: Rheumatoid arthritis (RA) is an autoimmune disease characterized by joint inflammation and damage in which fibroblast-like synoviocytes (FLS) play a central role. Invasiveness and proliferation of FLS in RA is dependent on activity of the KCa1.1 potassium channel. Peptide blockers of KCa1.1, such as iberiotoxin (IbTX), can be delivered subcutaneously to treat animal models of RA. We tested whether an engineered probiotic oral delivery platform could effectively deliver IbTX systemically in a rat model of RA.

Results: A plasmid for inducible secretion of IbTX was constructed and transformed into probiotic Limosilactobacillus reuteri ATCC PTA-6475 to generate LrIbTX. No differences …

Journal of the Saudi Heart Association

Background and objective:

Primary percutaneous coronary intervention (PPCI) is the gold standard for myocardial reperfusion in ST-segment elevation myocardial infarction (STEMI). Numerous studies have shown that thrombus aspiration can prevent distal embolization and reducing the risk of microvascular obstruction (MVO). Cardiac magnetic resonance (CMR) is considered the gold standard for the evaluation of MVO. The aim of this study is to evaluate the effect of thrombus aspiration in STEMI patients as an adjunctive technique to primary PCI in reducing the incidence and extent of MVO evaluated by CMR.

Methods

Ninety-three patients with heavy thrombus burden were enrolled in this study; …


Establishment Of Neonatal Sepsis Predictors Utilizing Non-Invasive Monitoring Techniques, Dalton Janssen Aug 2025

Establishment Of Neonatal Sepsis Predictors Utilizing Non-Invasive Monitoring Techniques, Dalton Janssen

Dissertations

Neonatal sepsis remains one of the leading causes of global neonatal mortality. Reactionary approaches for diagnosis and treatment have dominated the tactics in addressing neonatal sepsis but clinical intuition is an untapped resource that could lead to earlier prediction of sepsis onset. Nurses and other staff with specialized training and experience who have served as routine caregivers for a specific patient are able to identify when the patient’s status is altered. This clinical intuition may be substantiated by referencing specific patient trends in non-invasive measures over time. This retrospective, exploratory study examined whether variation in non-invasive monitoring variables could serve …


The Influence Of High Iq On Adhd Symptom Presentation And Outcomes In Children, David A. Lee Aug 2025

The Influence Of High Iq On Adhd Symptom Presentation And Outcomes In Children, David A. Lee

All-Inclusive List of Electronic Theses and Dissertations

Research suggests that a high intelligence quotient (IQ) may contribute to the underdiagnosis and misdiagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD) in children. High IQ may allow children to compensate for executive functioning-related deficits inherent in ADHD and/or may influence behaviors such as high activity level or not following rules that mimic ADHD symptoms. To gain a better understanding of the relationship between IQ and ADHD, the present study aimed to investigate how high IQ impacts symptoms of inattention and hyperactivity as well as outcomes related to academic performance, emotional regulation, and peer relationships in children. The study utilized archival data from …

Advanced Interactions Of Directed Energy With Retinal Pigment Epithelial Cells And Their Photochemical And Photothermal Responses, Jin B. Ha Aug 2025

Advanced Interactions Of Directed Energy With Retinal Pigment Epithelial Cells And Their Photochemical And Photothermal Responses, Jin B. Ha

Theses & Dissertations

Excess optical radiation can injure the retina through either rapid heat deposition (photothermal damage) or cumulative photo‑oxidative stress (photochemical damage), yet current laser‑safety limits treat these mechanisms as independent. To test that assumption, this dissertation integrated systematic wavelength, duration and temperature‑controlled laser exposures with live/dead fluorescence imaging in a melanin‑loaded hTERT‑RPE1 monolayer model. First, concurrent 447 nm (blue) and 2 µm (infra‑red) beams delivered for 200 s demonstrated a strong thermal–photochemical synergy: each beam alone was sub‑threshold (≤25 % lethality) but together produced 100 % RPE death without exceeding 50 °C, proving that modest heating markedly lowers the photon dose …

Hardware And Software Design For A Portable Surgical Training Simulator, Victoria Nelson

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

More than 51 million surgeries are performed on patients annually in the United States. That number grows to 310 million surgeries performed globally each year. Most surgeons go through a minimum of five years of residency – where they train and hone their surgical skills. It is important during this time, and throughout their careers, that they get plenty of practice. Surgical training is time intensive, expensive, and frequently under-resourced. There are finite amounts of surgical training modules for students to share at their facilities. The problem of getting adequate surgical training time continues to exist after surgeons begin their …


Multivariate Optical Imaging Of The Oxygen-Metabolism Axis, Jesse D. Ivers Aug 2025

Multivariate Optical Imaging Of The Oxygen-Metabolism Axis, Jesse D. Ivers

Graduate Theses and Dissertations

Metabolic reprogramming is a characteristic hallmark of multiple pathologies and promotes disease progression, survival, and severity. Current methods to investigate metabolic reprogramming, however, require reductions of dimensionality both because of instrumentation limitations and analysis tools. This work aims to define a blueprint for high dimensional study of the oxygen metabolism axis to enable more sensitive study metabolic reprogramming. We hypothesized (1) multivariate imaging of metabolic and oxygenation metrics in ex vivo tissue sections would elucidate differences in resistant and sensitive head and neck squamous cell carcinoma (HNSCC) xenografts that traditional uni-variate methods miss and (2) an engineered hyperspectral darkfield microscopy …

Respiratory infections in patients with cancer are common. A low threshold for bronchoscopy with bronchoalveolar lavage (BAL) should be maintained in immunocompromised patients with pulmonary opacities on chest imaging to evaluate for opportunistic infections. In those with unresolving symptoms, transbronchial biopsies may add significant diagnostic value. Concomitant hypercalcemia in patients with cancer is typically related to underlying malignant disease. However, in those with persistent respiratory symptoms or atypical infiltrates then granulomatous inflammatory diseases should be considered. Diagnosing histoplasmosis in immunocompromised patients can be difficult. Antigen testing is often more sensitive, but tissue biopsy or culture may be needed. We describe …

Diagnostic Accuracy Of The Stopbang Questionnaire Against Polysomnography For The Screening Of Obstructive Sleep Apnea In A Tertiary Hospital In Kenya., Sandra Obaje Maseno

Master of Medicine in Internal Medicine

BACKGROUND: Obstructive sleep apnea is a syndrome of upper airway and neuromuscular dysfunction during sleep that subsequently causes interruption of normal breathing. Polysomnography is the reference test for the diagnosis of obstructive sleep apnea. Obstructive sleep apnea can be categorised as mild, moderate or severe based on an apnea-hypopnea index (AHI) on polysomnography. The recommended treatment using Continuous Positive Airway Pressure lowers morbidity and mortality rates. The STOPBANG questionnaire has been used as a screening tool for obstructive sleep apnea due to its easy and concise approach. However, even with the increasing prevalence of obstructive sleep apnea and its risk …
