Filter by:Constitution of a biological collection within the framework of the establishment of a diagnostic, prognostic and active surveillance test for prostate cancer from long non-coding RNA biomarkers, in 3 cohorts of patients, with cancer of the prostate, with suspected cancer without biopsy confirmation or with prostatic hyperplasia and healthy donors. This biological collection will also be used as a support for further researches on the identification of biomarkers and genetic markers to improve the prognosis and diagnostic management of patients with prostate pathologies.
This research study tests a new medicine for mobilizing stem cells so they can be collected and used for allogeneic stem cell transplant for treatment of hematological malignancies. MGTA-145, the new medicine, will be given with plerixafor.
Evaluate the outcome of pediatric living donor liver transplantation (LDLT) regarding portal vein reconstruction, ABO-compatibility and impact of maternal donation on graft acceptance.
To test blood samples from volunteer donors of whole blood and blood components using a new investigational test that detects human immunodeficiency virus (HIV) infection. Results will be compared to the current HIV screening assay.
Primary Objective: This is a study to investigate the feasibility of harvesting, expanding, and selecting T lymphocytes from cancer patients and healthy volunteers. The preliminary objective of this study is aimed at selecting PD-1+ and CTLA4+ T cells and other cellular fractions from peripheral blood of cancer patients and healthy volunteers by using specific conjugated antibodies, evaluating their functional ex vivo anti-tumor cytotoxicity against targeted autologous tumor cells.
Background -NCI-Frederick scientists performing in vitro studies involving human specimens have a need for a reliable and consistent source of samples which protects the donor from research risks. Objective -The purpose of this protocol is to establish a centralized repository for the collection and distribution of samples (either blood, buccal mucosal cells, semen, urine, or nail clippings) from paid, healthy volunteer donors for in vitro research conducted by NIH investigators located at NCI-Frederick and Ft. Detrick. Research will include, but are not limited to, genotype analysis, immune function studies, drug screening, vaccine development, method development, quality control testing of reagents, and propagation of infectious agents, including HIV. Eligibility: Healthy NCI-Frederick employees and other NIH staff located at Ft. Detrick will be recruited. Potential donors will be excluded if screening indicates exposure to HIV, HTLV, Hepatitis C or Hepatitis B virus infection. Study Design: Investigators requesting to participate to the Research Donor Program (RDP) by receiving samples for research use will be required to submit a written memo of request, briefly describing the nature of the research and providing assurance that samples provided through this protocol will be used solely for in vitro research. These Investigators will receive samples that will be either anonymous or coded, depending on the specific need. Codes will be securely maintained and under no circumstances will donor identity be released to Investigators. Donors will receive financial compensation for their time, discomfort and inconvenience according to an established schedule; compensation for blood donation is based on the volume donated.
