Neuroblastoma (NB) is the most common extracranial solid tumor in children, accounting for about 15% of tumor-related mortality. NB patients in high-risk group are prone to bone marrow and/or bone metastases with low five-year overall survival rate. The artificial intelligence (AI) and deep learning technologies have potential to identifying morphological characteristics of bone marrow cytology in clinical practice. In this study, the investigators construct and evaluate the bone marrow cytology-based AI model for detection and prognosis of NB. The main questions of the study as follows: The question 1: Dose bone marrow cytology-based AI model work for prediction of bone marrow...
The study is being conducted to determine if a same-day, low-dose intravenous (into a vein) injection of indocyanine green (ICG) (FDA-approved dye) being detected by using an imaging system can be a useful tool in identifying and differentiating tumor tissue from normal tissues.
Under normal conditions our immune system protects us against infections and tumors. The immune system does this by recognizing that the infecting organism or the tumor is foreign to the body and attacking it. One way the immune system attacks a foreign target is by making proteins called antibodies that bind to the target. Sometimes, for reasons we poorly understand, the immune system wrongly identifies part of our own body as being foreign and attacks it. This can result in disease such as some forms of diabetes and thyroid disease, as well as some neurological diseases. In this study, one tablespoon of blood will be removed from each subject and tested to see if the immune...
Prospective phase 2a clinical trial to demonstrate proof-of-concept for simultaneous hyperpolarized [1-13C]pyruvate and 18F-FDG for positron emission tomography (PET) and MRS (magnetic resonance spectroscopy) in a PET/MR scanner in patients with cancer.
This Phase II trial tests if sonodynamic therapy (SDT)-a non-invasive treatment using ultrasound to activate a cancer-killing drug-improves outcomes for newly diagnosed glioblastoma patients. Who? 230 adults (<75 years) with confirmed glioblastoma, adequate organ function, no major health issues. Groups: Test Group: SDT + standard therapy (radiation, chemo, bevacizumab). Control Group: Standard therapy alone. Procedure: SDT uses the drug Hiporfin® followed by focused ultrasound sessions. Patients avoid sunlight for 1 month. Study Duration: Treatment: ~6-8 weeks. Follow-up: 24 months (monthly MRIs). Key Goal: Compare progression-free survival (time until...
1.Brief Introduction to the Research Background: You are invited to participate in a clinical study initiated by the First Affiliated Hospital of Zhengzhou University and chaired by Professor Zheng Yingjuan at our center. This two-year study aims to verify the sonodynamic therapy. It has been reviewed and approved for establishment by the Scientific Research Office of the First Affiliated Hospital of Zhengzhou University and has also obtained the approval of the Ethics Committee of the First Affiliated Hospital of Zhengzhou University to conduct the clinical research. This informed consent form provides you with relevant information about this clinical study to help you...
This is an imaging study of patients with mild Alzheimer's disease receiving amyloid-targeting therapy and under the care of neurologists at Mayo Clinic in Rochester, MN.
Cytokine-induced killer (CIK) cells exhibit high proliferation rate and cytotoxic activity in vitro. The major effector cells are the CD3+CD56+ subset. The cytolytic activity of CIK cells being independent of MHC restriction implies feasibility in using CIK cells allogeneic to the tumors. Experiments to block the MHC class-I and -II pathways on tumors-RNA transfected DCs showed that only MHC class-I blocking led to a significant reduction of heterogeneous CIK cells cytotoxicity after the co-culture. The safety of CIK cells was demonstrated by the lack of cytotoxicity toward autologous as well as allogeneic normal cells. Co-culture of CIK cells with dendritic cells (DCs) has...
A complete spinal cord injury (SCI) in men is characterized by the total loss of motor skills and sensations below the injury. The loss of penile sensation, the erogenous zone primarily involved in sexual response, is involved in sexual dysfunction, impacting sexual pleasure and quality of life. The management of genito-sexual dysfunction is a priority for paraplegic patients, ahead of bladder-sphincter and motor functions. For tetraplegic patients, the restoration of genito-sexual functions is their second priority after the upper limb motor skills recovery (Anderson, 2004)(Anderson et al., 2007). Medical assistance is currently available to i) restore erectile function...
Glioblastoma patients are confronted with a debilitating disease associated with a low survival rate and poor quality of life. The goal of this study will be to reach a largely underrepresented population in the exercise literature and explore the role of a tailored circuit-based resistance training program on functional fitness (i.e., ability to carry out tasks of daily living) and associated health outcomes (e.g., quality of life) for GBM patients on active treatment.
