Faculty, Staff and Students Publications

Chagas disease, caused by the protozoan Trypanosoma cruzi, is a significant challenge for canine health, with limited diagnostic tools. This study assessed the performance of a novel Tc-24 recombinant antigen ELISA compared to three commercial diagnostic tests on 70 serum samples from kennel dogs in Texas. The Tc-24 ELISA demonstrated high sensitivity (87.5%) and specificity (91.2%) compared to Indirect Fluorescent Antibody (IFA) testing, with significant differences in Tc-24 optical density (OD) between positives and negatives (0.607 vs. 0.089, p < 0.001). When compared to Chagas Stat-Pak (SP), Tc-24 ELISA showed sensitivity and specificity values of 82.1% and 86.7%, respectively (p < 0.001). For Chagas Detect Plus (IB), the assay achieved a sensitivity of 80.0% and specificity of 93.1% (p < 0.001). Spearman correlation analysis revealed significant associations between Tc-24 OD and SP (r = 1.0, p = 0.0167), IB (r = 0.9, p = 0.0833) and IFA (r = 0.6273, p = 0.044). Elevated immunochromatographic values in commercial kits (SP or IB) correlated with Tc-24 OD (1.17 vs. 0.039, p < 0.001), achieving 100% sensitivity and 95.8% specificity based on positive results from commercial kits. These findings suggest that Tc-24 ELISA is a reliable and accurate serological tool for diagnosing T. cruzi infection in dogs, with the potential to enhance diagnostic capabilities in veterinary medicine.

The Role Of Serum Phosphate Control In Supporting Transplant Readiness In Patients On Dialysis, Laura A Williams, Stephen Z Fadem

Faculty, Staff and Students Publications

Chronic kidney disease affects over 36 million Americans, with more than 800,000 progressing to end-stage kidney disease (ESKD). Treatment with kidney transplantation offers superior survival, quality of life, and cost-effectiveness compared with dialysis, yet access remains limited. Hyperphosphatemia is a highly prevalent and modifiable complication of ESKD that contributes to cardiovascular disease, mineral bone disorder, and potential pulmonary dysfunction. Additionally, elevated serum phosphate has been linked to transplant graft failure and adverse post-transplant outcomes. Although normal phosphate levels are not formally required for transplant eligibility, they are frequently considered as part of transplant readiness assessments. Persistent gaps between clinical guideline …

Faculty, Staff and Students Publications

Age-related macular degeneration (AMD) has significant genetic component, yet monozygotic twins frequently exhibit discordance in disease status, highlighting the role of non-genetic factors. To enable comparative studies of AMD pathogenesis, we generated two induced pluripotent stem cell (iPSC) lines from peripheral blood mononuclear cells (PBMCs) of a monozygotic twin pair discordant for AMD. These iPSC lines offer a unique genetically matched resource to investigate molecular differences between affected and unaffected twins, as well as their responses to genetic, epigenetic, and environmental contributors to AMD development.

Validation Of An Assay For Ngal In A Pediatric Population, Nazmin Bithi, Ridwan B Ibrahim, Estella L Tam, Radwa Almamoun, Annette C Frenk Oquendo, Ayse Akcan-Arikan, Sridevi Devaraj

Faculty, Staff and Students Publications

Background and objectives: Acute kidney injury (AKI) poses a serious clinical challenge, particularly in high-risk environments, due to its association with increased morbidity and mortality. Traditional diagnostic markers, such as serum creatinine, often detect AKI only after significant kidney damage has occurred, limiting opportunities for early intervention. Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as a promising early biomarker due to its rapid upregulation following kidney ischemia. NGAL supports renal recovery by reducing toxicity and promoting tubular regeneration via heme oxygenase-1 activity. This study aimed to validate the BioPorto ProNephro AKI™ turbidimetric immunoassay for urinary NGAL on the Ortho Vitros XT7600 …

Excision And Regional Flap Reconstruction With Radiation Therapy Of Granuloma Annulare Of The Digit: A Case Report, Austin Y Jiang, Linda K Green, David Netscher

Faculty, Staff and Students Publications

Granuloma annulare (GA) is a benign, often self-limited granulomatous skin condition that typically resolves spontaneously. Treatment is often not required, but topical and injectional corticosteroids are the most common interventions. Excision is effective for diagnosis and temporary treatment, but usually not considered curative. This case report describes the unconventional treatment of a recurrent biopsy-proven GA of the index finger. Due to the combination of the recalcitrant nodules interfering with function and patient preference, the nodules were excised multiple times. Ultimately requiring reconstruction with a pedicled radial forearm flap, the patient thereafter received radiation therapy to prevent recurrence, the combination of …

Acute Loss Of Tactile Input Leads To General Compensatory Changes In Eye-Hand Coordination During Object Manipulation, Kevin Ung, John F Magnotti, Brandon Kim, Jeffrey M Yau, Per F Nordmark

Faculty, Staff and Students Publications

Current models of motor control emphasize the critical role of sensory feedback, as demonstrated by movement coordination deficits following sensory impairment. When both vision and touch are available for object-oriented manual behaviors, they serve distinct roles; vision guides the execution of planned movements, while touch provides more direct feedback on hand-object interactions. The impact of losing somatosensory feedback on eye-hand coordination during dexterous object manipulation tasks has not been thoroughly studied. Conceivably, vision is recruited to compensate for the feedback lost when touch is abolished based on the dexterity demands of the behavior. To investigate this, we tested healthy participants …
