Filter by:The goal of this clinical trial is to test the roles of dopamine and norepinephrine in decision making related to loss aversion in the healthy population. The main question it aims to answer is whether temporarily boosting dopamine activity or temporarily suppressing norepinephrine activity has an impact on processing of potential gains and losses in financial decision making, social decision making, transaction decision making and moral decision making. Accordingly, participants will complete four decision-making tasks, namely investment task, driving task, trading task, and die task, after taking madopar, propranolol or placebo. Participants' psychological traits and psychiatric symptoms will be assessed once they are enrolled before the first-session day.
The purpose of this study is to evaluate the effect of castor oil versus placebo on intestinal permeability in healthy individuals.
This is randomized active-sham group controlled between-subject real-time fMRI neurofeedback trial aimed at modulating the ventromedial prefrontal cortex (vmPFC)-amygdala pathway to control subjective anxiety and arousal.
The aim of the present pilot randomized controlled trial is to compare the effects of the following: 1)-panettone enriched with arabinoxylans (p-rich), 2)-panettone not enriched (p-standard) on blood glucose and insulin values, and appetite scores in 10 healthy volunteers.
The primary objective of this study is to assess the construct validity and criterion validity for associations of the VEGANScreener with nutrient intakes from reference methods and associations with biomarkers of dietary intake. The investigators hypothesize that the screener is a valid tool to assess diet quality in the vegan population. The study will assess construct validity by testing whether the measure relates as it should to other measures (e.g., age, gender, education, SES differences). The investigators will assess concurrent and predictive validity (types of criterion validity) by evaluating associations and agreement between 'gold standards', such as diet records, biomarkers, and multi-metabolite signatures of intake. The investigators will examine associations of vegan diet quality with biomarkers of nutritional status, biomarkers of disease, and anthropometric measures and hypothesize that a higher diet quality in vegans is associated with a more favourable profile among vegans, for example, a lower blood pressure. This study is part of the European VEGANScreener Consortium.
This is an unblinded pilot study of an environmental exposure to secondhand cannabis smoke in one group of healthy nonsmokers.
The study was planned to consist of 24 healthy subjects in 3 dosing cohorts receiving a continuous i.v. infusion of KAND567 or placebo for 6 h (6 subjects on active and 2 subjects on placebo per cohort), with the option of two additional cohorts of the same size and group composition.
This research study will determine the effects of mango consumption on blood pressure, body weight, dietary nutrient/pattern changes, total cholesterol, LDL-cholesterol, VLDL-cholesterol, triglycerides, and HDL-cholesterol in individuals with moderately elevated blood pressure and/or LDL-cholesterol.
Objectives: Systemic autoimmune diseases are chronic diseases characterized by chronic inflammation, vasculopathy, and autoimmune phenomena. Several organ involvements are typical, including the central nervous system. Formerly published investigations emphasize a mild cognitive impairment affecting attention, memory, and complicated solution tasks. However, these symptoms significantly impact patients' routines and quality of life. The study examined the associations between cognitive impairment and clinical parameters regarding systemic autoimmune diseases. Methods: General clinical data, some serum biomarkers including CCl-18, YKL-40, COMP, VEGF, Galectin-3, and Pentraxin as well as results of functional, quality of life, and neuropsychological measures, the Mini-Mental State Examination (MMSE), the Digit Span Forward-Backward, the Trail making A, B and the Digit Symbol tests all were administered.
The purpose of this research is to further investigate the potential of brain stiffness as a novel biomarker for Alzheimer's disease.
