Filter by:The purpose of this study is to investigate the safety and tolerability of JNJ-64140284 versus placebo after single oral dose administration (ascending dose levels) under fasted condition, to characterize the pharmacokinetics (PK) of JNJ-64140284 in plasma, cerebrospinal fluid (CSF) and urine after single oral dose administration and to investigate the effect of food (high fat/high calorie) on the PK of JNJ-64140284 following single oral dose administration.
The primary aim of this study is to investigate the effects of exogenously administered nicotinamide riboside (NR) on brain NAD+/NADH ratio and bioenergetics functions in healthy individuals using phosphorus magnetic resonance spectroscopy (31P MRS) imaging. The secondary aims are to investigate the change in brain PCr/ATP and creatine kinase enzyme rate after NR use. In addition, NAD+/NADH ratio, PCr/ATP and CK enzyme rate will be measured in the calf muscle, as secondary outcome measures.
The purposes of this study are to determine: - The safety of the study drug and any side effects that might be associated with it. - How much of the study drug gets into the blood stream and how long it takes the body to remove it in healthy participants. Participants will be admitted to the Clinical Research Unit (CRU) for 3 overnight stays. This study involves a single dose of LY3002815 or placebo given as an injection into the vein. This study will last approximately 16 weeks including screening. Additional follow-up may be required. This study is for research purposes only, and is not intended to treat any medical condition.
The purpose of this study is to evaluate the safety and tolerability and pharmacokinetics of JNJ61803534 in healthy participants after administration of single ascending oral doses of JNJ-61803534 (Part 1) and multiple ascending oral doses of JNJ-61803534, administered for 14 consecutive days (Part 2) as well as the potential of JNJ-61803534 to interact with other drugs (Part 3).
The primary purpose of this study is to evaluate the effect of single and multiple doses of JNJ-64155806 on the steady-state pharmacokinetics (PK) of ethinylestradiol and drospirenone and vice versa in healthy female participants.
The study aimed to understand how payoffs for others influence perceptual decision making. The research consists in testing how varying monetary payoffs for another modify the perceptual decision making processes. The use of drift diffusion models on a random dots task enable the characterization of the decision parameter(s) that are modulated when a decision is made to win payoffs for others as compared to decisions for self-benefits. Once the parameter revealed through behavioral experiment, neuroimaging is applied to find the neural correlates of the effects of taking others into account in the decision making process.
The purpose of this study is to obtain lymphocyte collections from normal healthy volunteer donors in order to create Good Manufacturing Practice grade banks of virus-specific and tumor-reactive T-cells of defined HLA type and restricting HLA allele readily available for therapeutic use.
Randomized, double blind, placebo-controlled intervention trial on the ocular benefits and inflammatory markers improvements of taking FloraGLO Lutein for 9 months. The population of interest is middle-aged men and women who have low levels of carotenoids in their eyes.
Functional Magnetic resonance study on the effect of cognitive context variables on the perception and valuation of food odorants and flavor. The study is composed of two experiments; in a first experiment we address the question of how valuation of food odors are modulated by 3 cognitive conditions (indulgence, healthy, and neutral). Food odors are delivered using a custom-made olfactometer. Here we hypothesize that cognitive regulation can modulate the primary sensory processing of food odors. We expect that cortical regions related with valuation and cognitive regulation such as the ventromedial prefrontal cortex and the dorsolateral prefrontal cortex operate the modulation of primary olfactory cortex and amygdala. In a second experiment, we aim to reveal the brain areas involved in integrating food color cues with odor and taste stimuli. Here we hypothesize that color cues are capable of biasing flavor attributes of food (flavor intensity), and that this bias occurs at different cortical areas commonly associate with multisensory integration such as the orbitofrontal cortex, insula, amygdala and hippocampus.
The purpose of this study is to investigate neural mechanism of healthy humans underlying group decision making and compare it with that of individual decision-making. Using functional neuroimaging technology combining with computational modeling, we examine how the human brain process social information to make a decision within a group, which often guides humans to make a better decision using collective wisdom.
