  • A Study of the Role of the Forkhead Box O3a BNIP3 Pathway in Human Cardiovascular Disease Rochester, MN

    The purpose of this study is to collect cardiac biopsies and assess the activity of the signaling pathway in patients with cardiovascular disease by  using transmission electron microscopy to study mitochondrial structure and morphology and by assessing the biology of the genes and proteins of the FOXO3a effector, BNIP3.

  • A Study Investigating Integrated Genomics And Patient-derived Cancer Models Scottsdale/Phoenix, AZ; Jacksonville, FL; Rochester, MN

    The aim of this project is to characterize a landscape of DNA alterations and proteomic changes in both biopsies and resected tumors of patients which have been diagnosed with aggressive/metastatic disease to identify molecular targets for which therapeutic drugs may exist.

     

     

  • Inherited Muscle Diseases Repository Rochester, MN

    To establish a repository of DNA samples collected prospectively from patients with inherited myopathies of unknown molecular and/or biochemical defect. To access residual muscle specimens from diagnostic muscle biopsies obtained as part of the routine medical care. The biospecimens will be used to better understanding the underlying molecular defects and mechanisms of muscle diseases.

  • Congenital Heart Disease Skin Punch Biopsy Sample Collection Rochester, MN

    The purpose of this study is to Generate autologous iPSC in a manner compliant with requirements for future clinical use, and Reduce manufacturing time when patients are identified as eligible to receive product under separate interventional treatment protocol.

  • Leveraging AI/ML Algorithms On Digital Pathology And Ex-Vivo Confocal Microscopy Imaging For Extramammary Paget’s Disease Rochester, MN

    The purpose of this study is to validate the use of ex-vivo confocal microscopy for the assessment of skin specimens derived from Mohs surgery compared to standard microscopy. To leverage deep learning models for classification, detection, and localization of tumor for extramammary Paget’s disease on ex-vivo confocal microscopy images. To leverage AI/ML to ex-vivo confocal microscopy imaging to facilitate microscopic-level imaging of extramammary Paget’s disease. To leverage deep learning models for classification, detection, and localization of tumor for extramammary Paget’s disease on frozen and permanent pathology WSIs.

  • Image-based Mapping Of Brain Tumors Scottsdale/Phoenix, AZ; Rochester, MN

    The purpose of this study is to combine MRI images with histologic and genetic analysis of cancer (from blood and tissue samples) to improve the overall accuracy of diagnosis and effectiveness of cancer treatment.

     

  • A Study To Evaluate Advanced Development Of Desorption Electrospray Ionization Mass Spectrometry For Intraoperative Molecular Diagnosis Of Brain Cancer Jacksonville, FL

    The purpose of this study is to explore the translational abilities of desorption electrospray ionization mass spectrometry (DESI-MS) as intraoperative diagnostic tool to identify cancerous versus noncancerous tissue and estimate the percentage of tumor infiltration in tissue biopsies, by monitoring depletion of N-acetylaspartate (NAA) and aberrations of the phospholipid signature of neurological tissue; and to identify the presence of IDH mutations by monitoring the 2-hydroxyglutarate (2HG) and, therefore, differentiate between IDH-mutant and wild-type gliomas.

  • Feasibility Of Intraoperative Microdialysis During Neurosurgery For Central Nervous System Malignancies Rochester, MN

    This clinical trial evaluates the use of microdialysis catheters during surgery to collect biomarkers, and studies the feasibility of intraoperative microdialysis during neurosurgery for central nervous system malignancies. A biomarker is a measurable indicator of the severity or presence of disease state. Information collected in this study may help doctors to develop new strategies to better diagnose, monitor, and treat brain tumors.

  • Cutaneous Tissue Using Ex Vivo Fluorescence Confocal Microscopy Rochester, MN

    The purpose of this study, as a proof-of-concept, is to investigate whether ex vivo fluorescence microscopy can provide adequate visualization of cutaneous tissue for determination of non-melanoma skin cancer tumor presence in a sample of up to 250 residual skin specimens.

  • Ommaya At Biopsy Rochester, MN

    The purpose of this study is to determine the feasibility of placing Ommaya reservoirs at the time of biopsy to enable longitudinal CSF monitoring.

  • 3D Ultrasound For The Imaging Of Axillary Lymph Nodes In Patients With Breast Cancer Rochester, MN

    The overall goal of this project is to study a new 3D ultrasound imaging technology for evaluation of axillary lymph nodes in patients with breast cancer.
