Filter by:The primary objective of this study is to determine how daily consumption of kale changes the activity of human xenobiotic metabolizing enzymes. Secondary objectives are to measure absorption and metabolism of kale phytonutrients, and to determine how kale consumption affects gene expression related to metabolism and lipid measures associated with cardiovascular health.
To evaluate the safety, pharmacokinetics, pharmacodynamics and immunogenicity of N-Rephasin® SAL200 following single and multiple ascending doses in healthy male volunteers after continuous intravenous infusion over 60 minutes.
The study is designated to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of escalating multiple oral doses of AEF0117 in healthy adult male and female subjects.
Bioavailability of dietary supplement formulations in healthy volunteers after a single oral dose.
Background: The communication between a patient and clinician may have significant effects on treatment outcomes and one likely mediator of the communication-related treatment effects is patient expectations, as demonstrated by placebo studies in various clinical domains. To investigate the link between patient-clinician interactions and patient expectancy in a clinical setting, acupuncture is suggested an effective method, as acupuncture is a procedure with known non-specific treatment components. As a scene for investigating the importance of expectations on treatment outcomes, the investigators used acupuncture for relaxation effects. It is commonly reported that participants experience a sense of relaxation during acupuncture treatment, yet, it is not known if the effects are related to the specific effects of needling or non-specific effects associated with the treatment procedure. Aim: To investigate if communication type (positive or neutral) about the expected treatment outcome affected i) participants' expectations, ii) short-term relaxation effects in response to genuine or sham acupuncture or to rest, and to investigate if treatment expectations were related to outcome. Procedure: Volunteers, i.e. Swedish individuals in general, not part of any specific patient group, are given written and oral study information and are screened for study criteria. The volunteers giving informed consent are randomized to one treatment session a´30 minutes with a) genuine acupuncture or b) sham acupuncture (telescopic non-penetrating needles). They are compared to a non-randomized reference group that receive no acupuncture, just 30 minutes of rest. Within the three groups, participants are randomized to 1) positive communication or 2) neutral communication from therapists, regarding expected treatment effects. Outcome measures: Visual analogue scales (VAS) (0-100 millimeter) measured treatment expectations and relaxation, at baseline two hours before the treatment session, pre treatment (directly before the treatment session) and post treatment (directly after the treatment session). Heart rate, blood pressure, and salivary cortisol are measured pre and post treatment. Primary endpoint is change in relaxation pre to post treatment.
The study is an experimental observational study in ten healthy volunteers. Based on an in vitro study, it is hypothesize that a low dose epinephrine infusion will improve platelet function in healthy volunteers who have received ticagrelor. Volunteers fulfilling all of the inclusion and none of the exclusion criteria will be included. Enrollment will be continued until the required sample size is achieved (10 subjects). Once informed consent is obtained, screening data will be collected to determine each subject's eligibility for study participation. The total expected duration of subject participation is 18 days, from screening visit to end of follow-up. The active participation is 8h (study procedure 4 hours, observation period 4 hours).
The aim of the present study is to investigate changes in neural activity (BOLD signal), as measured using fMRI, in brain areas associated with emotional and working memory during task performance after single-dose administration of a novel selective alpha2c adrenoceptor antagonist (ORM-12741) in healthy volunteers. Further, it will be explored whether ORM-12741 affects connectivity between brain areas in rest, as measured using fMRI, and cognitive performance in the sample under investigation.
This is a randomized, single-blind, placebo-controlled study conducted on healthy male subjects at a single study center to assess the safety, tolerability and the pharmacokinetics of AZD9977 following multiple-ascending oral doses at steady state
The purpose of this study is to assess the PK of TAK-536 and effect of food on the PK following single oral administration of TAK-536 pediatric formulation in Japanese healthy adult male participants.
This experimental medicine study explores whether a single dose of losartan (50mg) versus placebo affects the processing of positive and negative stimuli, using fMRI.
