Filter by:Title: Collection of Peripheral Blood Mononuclear Cells (PBMCs) from Healthy People for the Expansion of T Cells for Adoptive Cell Therapy Background: New therapies are being developed that use a person s own immune system to fight tumors. Some of the tumors being studied include cancers caused by viruses. Researchers want to use the healthy cells of volunteers to perform research studies. To do this, they are collecting lymphocytes through leukapheresis. Objectives: To collect healthy cells from volunteers for research studies for new cancer therapies. Eligibility: Healthy people ages 18 and older Design: Participants will be screened with a standard donor questionnaire. It asks about their health and past medical problems. It also asks about risky behaviors that could increase their exposure to viruses or bacteria that could be transmitted through a transfusion. Participants will give a blood sample to make sure they are able to donate. They will have a physical exam. A finger stick test will check their hemoglobin, or red blood cell, level. They might give a urine sample. Participants will undergo apheresis. For this, a needle is placed in a vein in each of their arms. Their blood is taken from one arm. A machine separates the white cells from the red cells and plasma by a spinning process. The white cells are removed and directed into a plastic bag. The red cells and plasma are returned through the needle in the other arm. The entire procedure takes 4 6 hours. Participants may donate every 21 days in this protocol if they choose to. ...
This first-in-human (FIH) study will provide the first safety and pharmacokinetic (PK) data for G1T38 in humans and will allow further development of G1T38 in patients with cancer.
The aim is to investigate the impact that water absorption properties in adhesives has on adhesion.
The purpose of this study is to assess the safety and tolerability of acellular adipose tissue (AAT), intended for the repair of soft tissue defects in humans, in healthy volunteers. The investigators hypothesize that AAT will be safe and well tolerated upon injection into human soft tissue.
The purpose of this study is to evaluate the safety and tolerability of multiple oral doses of TAK-828 in healthy participants.
The purpose of this research is to identify and probe the neural networks involved in feedback processing. It aims at translating this knowledge to clinical populations in which this network is disrupted or compromised. It includes two studies: 1) with fMRI in healthy subjects to identify the neural bases of feedback processing on decision making using different types of feedback (neutral, social and monetary) presented either infra- or supra-laminary and 2) probing the role of one structure, the anterior cingulate cortex, using Galvanic Vestibular Stimulation (GVS) in healthy subjects. The interventional part consists in the administration of Galvanic Vestibular Stimulation (GVS), which by means of small intensity currents activates the vestibular organs and subsequently vestibular-related brain areas. GVS will be delivered to healthy participants engaged in behavioural tasks requiring the processing of feedbacks of different nature (e.g. social or monetary feedbacks)
Preclinical work suggests that D3 dopamine receptors may be important in the study of the pathophysiology of affective disorders, psychotic disorders and addiction. D3 receptors may also play a role in dystonia, Parkinson's disease and response to treatment of these disorders. However, there has been a lack of specific radioligands for imaging D3 receptors. This proposed protocol will evaluate the uptake of [18F]FTP as a more specific in vivo measure of D3 receptor binding in the brain in healthy volunteers subjects after injection of lorazepam vs placebo, and in cocaine-dependent subjects. Test-retest scans will evaluate the variability of [18F]FTP uptake measures in both healthy volunteer subjects and cocaine-dependent subjects.
Starvation and metabolic stress increase circulating ketone bodies, potentially providing the heart with an alternative oxidative fuel. Hyperketonemia reduces myocardial fatty acid consumption. It is unclear whether this is due to inhibited peripheral lipolysis or diminished uptake per se. Aim: To test whether infusion of 3-hydroxybutyrate (BHB) inhibits myocardial glucose and fatty acid uptake. Methods: Randomized, single blinded, cross-over interventional study in 8 healthy volunteers. Myocardial glucose and fatty acid metabolism studied by 11C-palmitate and 18F-FDG PET/CT. Experimental elevation of circulating ketone bodies by infusion of β-hydroxy-β-methylbutyrate.
Nutritional clinical trial to evaluate the effectiveness of different functional meat products on the nutritional status of healthy people
This is a single-site, randomized, double-blind, double dummy, placebo-controlled single and multiple doses study of Aramchol in healthy Chinese volunteers. The subject population that was enrolled for Aramchol 004 was not specifically designed to understand the PK profile of Aramchol in subjects of Chinese descent. Therefore, this study (Aramchol 015) has been undertaken to ascertain the PK profile of Aramchol following single and multiple doses in a Chinese population under fed conditions utilizing the light breakfast from Aramchol 004. This study will consist of two parts and the subjects will be assigned to two parts. In each part of the study, subjects will be enrolled in the study within 28 days of screening.
