Background: - The Vaccine Research Center (VRC) is dedicated to understanding immune responses associated with prevention and treatment of infectious diseases. To study these immune responses, researchers need to collect specimens and images from individuals who have recently had a vaccination or recovered from an infection. These specimens and images are used to study different diseases and immune responses, and can be used to investigate ways to prevent or treat different medical conditions. Objectives: - To evaluate blood and other tissue samples for immune responses to vaccines and natural infections. Eligibility: - Healthy volunteers at least 18 years of age who agree to donate specimens for research purposes. Design: * Participants will have clinical evaluations and will be asked to provide some of the following samples, depending on the research question being addressed. All procedures and sample donations are optional and voluntary: * Blood samples through regular blood draws (for whole blood) and apheresis (to collect specific parts of the blood such as plasma or white blood cells) * Urine, semen, saliva, or vaginal swab samples * Tissue samples or biopsy specimens * Undergo procedures such as bronchoscopy (lung and respiratory tract), gastrointestinal endoscopy (stomach and upper intestinal tract), or colonoscopy (lower intestinal tract) to obtain tissue samples * Undergo imaging studies such as positron emission tomography (PET) or computed tomography (CT) scans Duration of participation is variable depending on the research question but will usually last up to 1 year. - Participants will be compensated for participation.
Objective: To test the sensitivity of a proprietary novel filtration device designed to capture and concentrate circulating tumor cells (CTCs).

Background: Alveolar soft part sarcoma (ASPS) is a rare tumor. ASPS is resistant to chemotherapy and radiation. ASPS is characterized by slow growth. Currently no in vitro or in vivo models of ASPS exist for use in experimental therapeutic studies or biological investigations. Primary Objectives: Acquisition of blood and tissue from patients with ASPS. Acquisition of blood from healthy controls for comparison with blood from patients with ASPS. These control samples will be obtained from study NCI at Frederick Protocol OH99-C-N046. Eligibility: Subjects of any age with a diagnosis of primary or metastatic alveolar soft part sarcoma who are undergoing medically indicated surgery for their disease. Design: Patients with Alveolar Soft Part Sarcoma (ASPS) will be eligible for this study. Biopsy tissue will be obtained as an additional sample at the time of a medically indicated procedure. Blood sample may be collected at initial visit and follow-up visits. Specific risks will be described in a separate consent to be obtained at the time of the biopsy. Tumor samples and blood samples will be processed and/or stored for use in research efforts in the laboratory of Dr. David Vistica, National Cancer Institute, Frederick, MD. Additionally, blood samples will be obtained from healthy volunteers for comparison to patients with ASPS. These control samples will be obtained from the National Cancer Institute at Frederick Protocol OH99-C-N046.
This study collects specimens from volunteers for use in studies by NIAID's Vaccine Research Center. A number of different types of specimens or samples can be collected, including blood, urine, body fluids or secretions, skin swabs, or skin biopsies. The samples are used for medical research, including the study of HIV, hepatitis, and other diseases; immune system responses, such as responses to vaccinations or infections; and for research on vaccine development. Blood samples may be collected either by ordinary blood drawing (phlebotomy) or by apheresis, a procedure for collecting a larger quantity of blood cells or plasma than would be possible through simple blood drawing. For this procedure, the participant lies on a recliner or couch. Blood is removed through a needle in the vein of one arm and spun in a machine that separates out the desired component (plasma or white blood cells). The remainder of the blood is returned either through the same needle or through a needle in the other arm. The procedure takes about 1 to 3 hours. Volunteers who are 18 years of age and older, including participants in other NIH research protocols, may be eligible. Individuals who have a condition that the research staff considers a reason not to make a sample donation will be excluded from the study. Participants may have only one sample collected or may be asked to undergo repetitive sample collection procedures, depending upon the requirements of the particular research project for which the samples are being collected. Each individual's enrollment is for a 1-year period, which can be extended.
Background: Urothelial cancer is cancer of the bladder, ureter, and urethra. Researchers want to better understand what changes in a person s cells and genes cause this cancer to form. This may help them find new ways to treat it. Objective: - To perform DNA sequencing to help researchers learn the differences between normal tissue and tumor tissue. Also, to learn how molecular changes - including gene changes - might help predict the course of disease and how people respond to therapy. Eligibility: - Adults age 18 and older who have or are suspected of having urothelial cancer or an inherited disorder that raises their risk of getting bladder cancer. Design: * Participants will be screened with a physical exam. Their medical records and tissue samples will be reviewed. * Eligible participants will give tissue blocks of their original tumor. The blocks will be put in a tissue bank. * Participants medical records may be reviewed. * Participants may have a medical history and physical exam. * Participants may have blood and urine tests. They may have imaging scans. They may give urine, blood, and saliva samples. These samples may be used in future research. * If participants need surgery for their cancer, researchers will keep some of the tissue (both tumor and normal tissue). The tissue may be used in future research. * Participants will go back to the Clinical Center in 6 months. They may give saliva, urine, and blood samples. After 6 months, they will be seen by their local doctor for standard post-surgical visits. * Participants will be called every 6 months to give health updates.
The study objectives are described below: 1. Obtain matched serum, plasma \[(K2 EDTA, Sodium Heparin (NaH), Lithium Heparin (LiH)\] and urine specimens collected from a minimum of 50 healthy subjects. Specimens will be used to determine a reference range for C-peptide and insulin assays, used as an aid in the assessment of C-peptide and insulin in adults. 2. Obtain serum and urine specimens collected from a minimum of an additional 200 healthy subjects. Specimens will be used to determine a reference range for C-peptide and insulin assays, used as an aid in the assessment of C-peptide and insulin in adults. 3. To store any remaining specimens for use in future assay development and to evaluate as yet undetermined assays for the development of IVDs, including additional C-peptide or insulin assays.
This is a protocol to collect tissues, blood, and other specimens from patients with malignant or nonmalignant diseases of the head and neck. Collected specimens will be used in laboratory studies to investigate the growth, development, and transformation of normal and abnormal cells in the future.
This research trial collects and stores blood, tissue, and bone marrow specimens from patients with cancer or blood disorders, and healthy volunteers to study the immune system in a variety of different types of experiments, as well as associated clinical data as appropriate, focused on understanding mechanisms of immunotherapy.
This study will collect tissue specimens to be used for research on inflammatory bowel disease. The tissues will be used to explore why people get inflammatory bowel disease and to try to develop new treatments based on the study results. Tissue from patients with IBD will be compared with that from patients who do not have the disease Patients who undergo bowel surgery for inflammatory bowel disease (IBD) or another bowel disorder may be eligible for this study. Patients with IBD must be at least 4 years of age; those with another disorder must be 18 years of age or older. Participants undergo bowel surgery for their disease. Some of the intestinal tissue removed during the surgery that is not needed for medical care, such as for pathological examination, is provided to researchers for study under this protocol. In addition, patients with IBD provide a blood sample for genetic testing. Several genetic variations, or mutations, may increase the risk of developing IBD; blood samples from patients may help identify these variations.
The purpose of this study is to obtain biologic materials from the blood, airways and/or urine of normal individuals and individuals with lung disease. The normal are used to establish a set of normal ranges for various parameters. These provide control information when compared to individuals with various pulmonary diseases, and will help in understanding of the etiology and pathogenesis of various lung diseases. The underlying hypothesis is that the pathologic morphological changes in the airway epithelium must be preceded by changes in the gene expression pattern of the airway epithelium and potentially in macrophages.
This study will collect biological samples for use in research experiments aimed at better understanding the clinical features of certain diseases. The specimens may be used to evaluate the effectiveness of known therapies, refine treatment approaches, identify potential new therapies, and explore opportunities for disease prevention. The following individuals 2 years of age or older may be eligible for this study: * Patients with a cancerous solid tumor or a cancerous or non-cancerous blood disorder who are being screened for or who are enrolled in a treatment study at the NIH Clinical Center * HLA-compatible donor family members (18 years of age or older) of the above patients who are being evaluated for or are enrolled in an NIH study as a stem cell transplant donor * Patients with a cancerous solid tumor or a cancerous or non-cancerous blood disorder or a bone marrow failure condition who cannot participate in an NIH treatment protocol or travel to the NIH Clinical Center and who are referred for participation through their home health care provider. Research samples will be collected from participants when blood is drawn or bone marrow, urine, or stool is collected, or tumor or other tissue is biopsied as part of their general medical care. Investigators may periodically request an additional sample of blood, stool, or urine. Participants who are 18 years of age or older may donate a large number of white blood cells through a procedure called leukapheresis. This procedure is not part of general medical care and would be done for research purposes only. For apheresis, a catheter (plastic tube) is placed in a vein in the subject's arm. Blood flows from the vein into a cell separator machine, where the white cells are separated from the red cells, platelets, and plasma by a spinning process. The white cells are removed and collected, and the rest of the blood is returned to the subject through a second tube placed in the other arm.
Background: - Laboratory research studies require control samples from healthy volunteers to compare with samples from patients. These studies will help researchers better understand and refine treatments for immune system and inflammatory diseases. Objective: - To obtain blood, urine, buccal (mouth) mucosa, normal tissue and bone marrow samples and/or leukopheresis cells from healthy volunteers. Eligibility: - Healthy individuals at least 8 years of age. Design: * Volunteers will be recruited through the Program for Healthy Volunteers, Patient Recruitment and Public Liaison Office, or self-referral through the clinicaltrials.gov Web site. * Health will be confirmed by a brief history and physical examination and blood work. * Volunteers 8 years of age and older will provide blood and urine samples using standard procedures. Buccal mucosa samples will be obtained by scraping the insides of both cheeks with a sterile nylon brush. * Bone marrow samples will be obtained from volunteers 18 years of age and older by taking two aspirates from the posterior iliac crest (an area near the hip). * Normal tissue samples will be obtained from volunteers 18 years of age and older by taking superficial skin samples (punch biopsies) * Leukopheresis or lymphapheresis will be performed on volunteers 18 years of age and older to obtain white blood cells for research * Samples will be assigned a unique code and will be stored until they are no longer of scientific value or the volunteer withdraws consent for their use.
The Hematology Branch of the National Heart, Lung, and Blood Institute is doing a variety of laboratory research experiments that require blood and tissue samples from healthy volunteers. This protocol provides a mechanism for collecting these tissue samples. Research includes studies of normal and abnormal formation of blood cells, viral blood diseases, the role of the immune system in marrow failure and genetic risk factors for aplastic anemia. Healthy normal volunteers 8 years of age and older may be eligible for this study. Samples are collected as follows: * Blood samples: Participants 8 years of age and older donate up to 4 tablespoons of blood, which is obtained from a needle placed in an arm vein. * Participants 8 years of age and older donate a buccal mucosa sample (cells from the inside of the cheek). The inside of the cheek is scraped gently with a nylon brush. * Participants 18 years of age and older donate a bone marrow sample. The bone marrow is obtained from the hip bone. The skin over the area is wiped clean with alcohol and iodine, and then a local anesthetic is injected under the skin and also into the bone. When the area is numb, a bone marrow aspiration needle is introduced through the bone surface into the marrow. The marrow cells are collected using a syringe connected to the needle.
This study will examine blood, bone marrow, tumor and tissue samples from patients with cancer to study tumor resistance to chemotherapy (drug treatment). Many patients with cancer improve initially with chemotherapy, but then have a disease relapse, after which their tumor no longer responds to treatment. Other patients tumors are drug-resistant from the start. The study will look for "resistance factors"-substances in blood and tissues that render tumors resistant to chemotherapy. The findings may provide information needed to develop methods of combating drug resistance. Patients with cancer who are 18 years or older may be eligible for this study. Participants will have 40 milliliters (3 tablespoons) of blood drawn at the beginning of the study; additional samples will be obtained periodically during the course of treatment. A small sample of tumor or normal tissue will be taken from patients who undergo surgery or tumor biopsy (removal of a small piece of tumor) for medical reasons or as part of a research treatment protocol. Patients who do not require surgery or biopsy may be asked permission to obtain a tumor sample. Depending on the location of the tumor, this may be done by: 1) withdrawing bone marrow through a small needle; 2) removing fluid from the chest or abdomen; 3) removing a small tumor sample through a needle; or 4) removing the sample with a small incision into or around the tumor. These procedures will be done only if they are of low risk to the patient.
