Filter by:This is a randomized, double-blind, and placebo controlled. 120 HV will be randomized to one of three ketamine arms, delivered in a bolus dose over one minute: low (0.086 mg/kg), medium (0.125 mg/kg), and high (0.23 mg/kg). Within each ketamine arm, subjects will be randomized to 4 days of TS-134 20 mg or placebo in a 5:3 ratio (25 TS-134:15 placebo). Following an outpatient Screening Period (up to 31 days), eligible subjects will undergo an up to 5-day inpatient Treatment Period. During the study, each subject will undergo a total of two ketamine sessions: a first session during the Screening Period and a second session on Day 4 of the Treatment Period, conducted at least 7 days apart. All randomized subjects will be dosed with TS-134 or placebo daily in a fed state for 4 days during the study, titrated to 20 mg over the first 2 days.
The experimenters will examine the relationship between utilization of positive (target cue) and negative (distractor cue) templates during a cued visual search task with performance on a set of measures related to executive functions associated with attentional control: shifting, updating, and inhibition.
The purpose of this study is to assess the antiviral activity of JNJ-64281802 versus placebo in terms of reduction of dengue virus 1 (DENV-1) ribonucleic acid (RNA) viral load (VL).
The long term goal for the Traumatic Injury Research Program (TIRP) is testing of novel devices for the identification and longitudinal assessment of traumatic brain injury (TBI). The Department of Defense (DoD) has now tasked TIRP with the test and evaluation of these devices to assess reliability and validity. The objective of this effort is to test the reliability of the NeuroKinetics Inc (NKI), i-PAS (portable assessment system) device using a test/re-test protocol with healthy controls. The basic research design adopted here is the test/re-test paradigm with three assessments obtained on three separate visits. This will allow the assessment of reliability of both the device and the measure(s) that are computed from the input signals. Participants will be Healthy Controls (HC) as defined in the inclusion exclusion section. In this initial study we will be administering standardized self-report instruments ( Short Form - 36 (SF-36) and the Symptom Checklist-90 (SCL-90r)), standard three-lead electrocardiogram. In addition we will administer the NKI i-PAS specific protocol as delineated by NKI.
Individuals infected with HIV have a high risk of developing metabolic comorbidities not traditionally associated with the immune dysregulation and deficiency associated with HIV infection and AIDS. Many of these comorbidities in HIV uninfected individuals have been linked to a disordered circadian clock function. The study investigators will further evaluate the circadian clock in HIV infection as a mechanism underlying the metabolic dysregulation in this population.
Our study goal is to assess natural patient-therapist interactions in order to map such human-human activities to robot-human interactions. Critical to accomplishing this mapping will be determining the feasibility of a humanoid robot interacting with a patient in a more intuitive and flexible way, while concomitantly investigating the issue of safe contact and release.
This study wishes to look at the 24-hour rhythm of certain fats in the blood stream. Recent studies in animals and healthy participants suggest that unusual eating habits may be connected to a change in the 24-hour rhythm of the blood fats the investigators wish to measure. The investigators will ask persons suffering from night eating syndrome, a condition where people eat additional meals throughout the night, to participate in this study. Healthy volunteers who are of the same age and gender, and have a comparable body-mass-index, a number calculated from a person's weight and height, will also be asked to participate. The aim is to learn how the 24-hour rhythm of the blood fats the investigators measure differs between the persons experiencing the night eating episodes and persons who do not.
The purpose of this study is to determine whether oxytocin affect face perception
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of the drug AZD5099 after intravenous administration of single doses in healthy volunteers. The results from this study will form the basis for decisions regarding the future development of AZD5099 as a novel antibiotic for the treatment of serious infections in humans.
Subcutaneous injections are a widely used method for drug delivery. One of its major drawbacks is the pain inflicted during the process. Sindolor has developed the chemical-free EZ-Ject Injector device, based on employing cutaneous local anesthesia on the injection site by an electronic anesthetic system. The purpose of this study is to determine the safety and efficacy of the EZ-Ject for subcutaneous injections.
