Filter by:This project aims to investigate the effect of modafinil on motivation, creativity, cognitive performance, and subjective wellbeing in healthy participants. The main task for this research project is to address how this novel stimulant acutely influences motivation, divergent and convergent thinking, cognitive performance and subjective wellbeing in non-sleep deprived healthy young adults.This is a randomised between-subjects parallel group design study. Based on the hypothesis that psychostimulants might enhance creativity through the increase in of dopamine and executive planning in healthy adults , we predict that healthy individuals who are in the modafinil condition will perform better in the motivation, creativity, and the cognitive performance tasks. Furthermore, based on the evidence that modafinil increases dopamine in the nucleus accumbens, putamen and the caudate, we expect specific subjective well-being and pleasure enhancement associated with modafinil use in healthy young adults.
One of the biggest challenges of today is the high stress levels among employees in companies and organizations. Physical exercise may be an effective preventive measure for stress-related problems. This relatively simple and inexpensive action is believed to be important for increasing and maintaining work ability and reduce the cost of stress-related ill health in the workplace. The aim is to investigate how regular physical exercise affects the individual's ability to mentally and physiologically cope with stress. Acute stress physiological responses are measured before and after a 6 -month intervention, where 100 untrained individuals are randomized to either regular physical exercise or a control group. The hypothesis is that exercise leads to lesser activation of the individual's stress physiological systems and to an efficient physiological protection system. Mental ability to handle stress is also studied as well as possible effects on the brain's cognitive functions. From a work perspective, cognitive impairment due to high exposure to stress is a major problem leading to substantial costs in businesses and organizations as a result of reduced performance and production. We believe that physical activity can alter and mitigate individual stress reactions. This study brings new knowledge that can contribute to increased motivation to prioritize physical activity in everyday life. The study could also provide evidence for businesses and organizations of the benefits of engaging in interventions and fitness initiatives to facilitate/enable increased physical activity in daily life for its employees. With an aging population, we are expected to work longer, which poses a challenge as the ability to manage stress and maintain cognitive abilities decline with age. For older employees, regular physical activity could be an important factor directly affecting the prospects for a sustainable working life.
This is a study designed to look at how arousal levels in the brain change with age and how these changes influence thinking, vision, hearing and physical function in people of advanced age.
In this first in human study the aim is to assess the safety, pharmacokinetics and pharmacodynamics of 2B3-201 in a randomized, first in human, double-blind, placebo- and active comparator- controlled 3-way crossover study in 18 healthy male subjects (part 1). Furthermore, the findings obtained from part 1 will be extended and confirmed in a subsequent parallel open label study in 18 healthy male and 12 MS patients and an open label study with methylprednisolone as comparator in 12 female volunteers (part 2).
This non-drug, single center, 24-week, longitudinal study in ambulant spinal muscular atrophy (SMA) patients and in age- and gender-matched healthy volunteers will assess the detection of disease progression by magnetic resonance imaging (MRI) and the Muscle Function Measure (MFM) test. Each participant will be evaluated in three testing sessions: at baseline, at Week 12 and at Week 24. Both patients and volunteers will undergo MRI scans. Patients will additionally undergo testing of motor function and have blood samples taken for Survival of the Motor Neuron (SMN) genes, proteins and mRNA analysis.
The purpose of this study is to assess the effect of coadministration of a high-fat meal on the oral bioavailability of a fixed dose combination of Canagliflozin/extended release Metformin (CANA/MET XR) tablet, containing 150 mg CANA and 1,000 mg extended release MET in healthy participants.
The purpose of this study is to evaluate the multiple dose pharmacokinetics of 2 Canagliflozin/extended release Metformin (CANA/MET XR) fixed dose combination tablets (150 mg/1,000 mg each) following once-daily oral dosing in healthy participants.
This is an open-label, randomized, 3-period crossover, single dose study. Three (3) single doses of AZD3293 (2 different tablet formulations, and an oral solution) will be administered with a washout period of at least 1 week between the doses to investigate the relative bioavailability of AZD3293 after administration via 2 tablet formulations compared with oral solution and to evaluate basic systemic pharmacokinetic parameters of the tablet formulations compared to the oral solution of AZD3293. The safety and tolerability of AZD3293 in healthy subjects will also be assessed in the study. AZD3293 is being developed for the treatment of Alzheimer's disease
This study will be a single-center, multiple-dose, randomized, double-blind, placebo-controlled, parallel-group study in healthy male and female subjects. The study will consist of 2 parts: Part A (3 cohorts of healthy Japanese subjects dosed in the evening) and Part B (one cohort of healthy white subjects dosed in the evening). The cohorts will be conducted sequentially. Part A will be started first with the 2.5-mg dose cohort, followed by the 10-mg dose cohort and then the 25-mg dose cohort. Part B will be conducted in parallel with the 10-mg cohort of Part A, with the possibility of overlap.
The purpose of this study is to select the optimal formulation of the norovirus vaccine from different concentrations of virus-like particles (VLP), Aluminum Hydroxide and MPL adjuvant (3-O-desacyl-4'-monophosphoryl lipid A) for further development.
