The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate Charcot-Marie-Tooth disease research and drug development by using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and/or store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for Charcot-Marie-Tooth disease.
The goal of this observational study has the purpose of collecting biological samples from obese patients undergoing evaluation for weight loss by means of medical or endoscopic therapies; and of post bariatric surgery patients presenting with short- and long-term surgical complications. The aim is to enhance the overall understanding of the mechanisms leading to obesity, weight loss, failure to lose weight, and weight regain following treatment. Additional goals are to determine the efficacy of endoscopic and surgical procedures, to identify potential therapeutic targets and disease biomarkers that predict response to therapy.
Background: Laboratory tests that use blood and urine can provide a great deal of information about human health and disease. To develop even better tests and to improve the ways samples are handled for testing researchers need to experiment with samples from healthy people. Objective: This natural history study will collect blood and urine from healthy people. The samples will build a repository that will be used for all kinds of research. Eligibility: Healthy people aged 18 years or older. Design: Participants will have 1 study visit. The visit will last up to 2 hours. Participants will be screened. They will answer questions about their health history. They will list any medications they take. They will consent to donate samples for research and future use: Blood: Up to 4.5 tablespoons of blood may be collected from a needle inserted into a vein. Urine: Participants will be given a sterile container to provide a sample. Some participants may be asked to provide other types of samples. Some participants may be asked to provide new samples if their first ones are depleted.
The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to study different conditions and diseases by using cells from the body (such as skin or blood cells). NYSCF uses these samples to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and/or store these samples for future use. Through this research, scientists hope to identify future treatments or even cures.
This protocol will use leukapheresis to collect lymphocytes to study immune responses following vaccination with BCG in BCG-naïve participants. These studies will include, but not necessarily be limited to: anti-T-cell and anti-Natural Killer (NK) T-cell responses, anti-lipid responses, and antibody responses to BCG following re-vaccination. These responses will provide a detailed framework characterizing the immune responses that are induced and responses that are not induced in humans by BCG, a partially protective TB vaccine. This framework will allow new hypotheses to be formulated and tested regarding what new and more effective TB vaccines should target for optimal protective immunity.
This laboratory study is collecting and storing samples of tissue and blood from young patients with Hodgkin's lymphoma. Collecting and storing samples of tumor tissue and blood from patients with cancer to study in the laboratory may help the study of cancer in the future.
This research study is collecting and storing samples of tumor tissue, bone marrow, and blood from patients with Ewing sarcoma. Collecting and storing samples of tumor tissue, bone marrow, and blood from patients with cancer to test in the laboratory may help the study of cancer in the future.
The purpose of this trial is to collect plasma, serum, whole blood and tissue samples from women with breast cancer and plasma, serum, whole blood from healthy women, which will be made available to researchers for biomarker analysis.
This study will collect samples of blood, stool, bone marrow, or other tissues from patients with hepatitis-associated aplastic anemia to investigate a possible association between exposure to viruses and the development of aplastic anemia in these patients. Cells from the samples obtained may be grown in the laboratory for future studies. Patients samples may be used to: * Study abnormalities that occur in hepatitis-associated aplastic anemia; * Test for various viruses; * Test immune function; * Measure factors related to the patients disease or diseases they may be at risk for; * Evaluate the effectiveness of current therapies, refine treatment approaches, and identify potential new therapies; * Identify possible measures for disease prevention; * Identify possible genetic factors associated with hepatitis-associated aplastic anemia. Patients 2 years of age and older with severe aplastic anemia that developed within 6 months of an episode of hepatitis may be eligible for this study. Participants will complete questionnaires and provide tissue samples as described below. Questionnaires All patients (or another respondent for the patient) will fill out a questionnaire including demographic information (age, gender, race, ethnic group, education level, state of residence), current symptoms, medications, medical history, and history of possible exposures to toxins or viruses. A second questionnaire, which includes questions related to mental health, sexual behavior, alcohol and drug use, is optional for participants age 21 and older. These questionnaires are designed to uncover features of hepatitis-associated aplastic anemia and possibly reveal a common cause of the disease. Sample Collections * Blood- will be collected at the time of the patient s initial evaluation or upon enrollment into the study and possibly periodically during the study. Blood will be drawn through a needle in an arm vein. * Bone marrow- may be collected as part of the patient s standard medical care or specifically for research purposes of this study. For this procedure, the skin over the hipbone and the outer surface of the bone itself are numbed with an injection of a local anesthesia. Then, a larger needle is inserted into the hipbone and marrow is drawn into a syringe. Marrow cells are suctioned two to six times during the 15-minute procedure. * Stool- will be provided by the patient. Liver- tissue may be biopsied as part of the patient s general medical care or for NIH patients, as part of their enrollment in a treatment protocol.
Patterns of illness among children in the United States and other industrially developed nations have changed substantially during the past 100 years. Before and during the first half of the previous century, infectious diseases were the primary threat to children s health. In contrast, the major illnesses and disorders that impair health, growth, and development today are chronic conditions stemming from the complex interaction of environmental exposures and inherent genetic factors. The Children s Health Act of 2000 directed the National Institute of Child Health and Development to conduct a national longitudinal study of environmental influences on children s health in the United States. The act specified that the study extend from the prenatal period to adulthood and investigate the short-term and long-term influences of physical, chemical, biological, and psychosocial environmental exposures on children s health and development, including behavioral, emotional, and educational outcomes in addition to physical health. The National Children s Study (NCS) is an observational longitudinal study that will enroll and follow a nationally representative sample of approximately 100,000 U.S.-born children from before birth through their 21st birthday. The study will screen all households within selected areas of 105 locations (primarily counties). The major types of analysis of NCS data will include longitudinal exposure-outcome analysis, identification of causal pathways, analysis of neighborhood effects, evaluation of temporal effects within longitudinal data analysis of data from case-control data, and analysis of genomic data. Women in their first trimester of pregnancy will be invited to participate in the pre-pregnancy portion of the NCS. Women who are not pregnant but have a high probability of becoming pregnant will be asked to participate in the early pregnancy portion of the NCS. All other eligible women will be asked if the study can contact them periodically to assess their pregnancy status. They also will be asked to contact the NCS should they become pregnant. Women identified as pregnant within 4 years after initial screening will be invited to enroll in the NCS. The following information will be gathered: Mother s data and information * Questionnaire data interviewed and self-administered (e.g., demographics; current pregnancy history; reproductive history; medical conditions; health behaviors; doctor visits; medicines and supplements; housing characteristics; pesticides, product use; occupation, hobbies; depression, stress; social support; diet; time and activity) * Physical measures and clinical data (e.g., blood pressure, sonograms, height, weight, body measurements) * Biologic specimens (e.g., blood, urine, hair, saliva) * Environmental samples during home visits (e.g., dust, air, water) * Medical record abstraction Infant s data and information at birth * Cord blood and tissue samples of the placenta and umbilical cord * Standardized neurobehavioral exam * Physical measures and clinical data (e.g., length; weight; circumferences of head, arm, abdomen, thigh) * Meconium samples * Medical diagnoses and treatment by report * Selected Medical record abstraction
This is not a treatment study. The overall objective is to develop an improved standard of care through studying blood, tissue, biological, etc. samples, that patients have allowed researchers to procure.
