Filter by:This pilot study will compare the effect of combining dietary nitrate and caloric restriction versus dietary nitrate alone. The participant will be contacted, having responded to an advertisement on social media and posters, to attend the screening visit. They will be asked about their health status, suitability for MRI and availability. The investigators will use physical activity and eating attitude questionnaires. The investigators will also measure their height, weight, body mass index (BMI), and blood pressure (BP) and undertake blood tests. If they are eligible, they will be randomised to one of the two arms. The first group will consume nitrate-rich beetroot juice with a calorie-restricted diet for 28 days. The second group will drink the same juice with a weight-maintenance diet for the same period. The food and drinks will be provided. The outcome measures will be measured twice (at the baseline and end visits) to evaluate the change. The primary outcome is the cognitive function. The secondary outcomes are peripheral vascular health (BP and microvascular perfusion), cerebral vascular health (brain blood flow), anthropometry, body composition, and exhaled NO and nitrate concentrations. Also, the feasibility and accessibility of the study will be assessed.
To study the effect of fractionated 1927-nm non ablative thulium laser in reduction of post inflammatory hyperpigmentation (PIH) using a validated and reproducible model for studying PIH. - Determine if there is aa reduction in PIH in patients treated with three (3) monthly sessions of fractionated 1927-nm non ablative thulium laser - Determine if there is efficacy of post-procedure clobetasol propionate 0.05% ointment in the management of PIH - Determine the histological and molecular changes that occur with laser and laser plus topical steroid treatment compared to untreated skin
The purpose of this clinical study is to validate the SpO2 accuracy of the Stryker Sustainability Solutions pulse oximetry sensors during motion conditions over the range of 70 -100% SaO2 as compared to arterial blood samples assessed by CO-Oximetry during conditions in which the subject is moving. The end goal is to provide supporting documentation for the SpO2 accuracy validation of the reprocessed sensors with motion indications.
In this randomized controlled trial, two different plant polar lipids are investigated with respect to their potential to affect acute and second meal glucose tolerance and appetite sensations. The effects are compared with a common non-polar commercial oil. The lipids are consumed spread on a white wheat bread. A white wheat bread without added lipids is included as a control product. The test products are consumed at breakfast, and test variables are investigated in the postprandial period after the test breakfast and also after a second meal standard lunch.
The goal of this trial is to investigate safety, tolerability and pharmacokinetics of BI 1584862 in healthy male subjects of Japanese ethnicity following oral administration of single rising doses.
Validate the performance of Philips FAST SpO2 with Masimo Pulse Oximetry Sensors in determining functional arterial oxygen saturation (SpO2) using arterial saturation (SaO2) as a reference in the range of 70-100% in subjects of varying skin pigmentation.
The purpose of this study is to measure side effects of LY3971297 injection administered under the skin in healthy participants and obese participants with high blood pressure (BP). Blood tests will be performed to check how much LY3971297 gets into the bloodstream and how long it takes the body to eliminate it. This is a 5-part study. The study duration will be approximately 60 days for Part A and approximately 90 days for Parts B, C, D, and E.
The goal of this prospective interventional study is to examine if repeated brief hot stimuli affects glucose metabolism and substrate oxidation in young non-obese adults. Young adult participants were asked to participate in fourteen 5-min procedures involving whole body passive heating at 45°C water. The main question it aims to answer is: "Does repeated brief noxious heat stimuli is sufficient to improve glucose tolerance, insulin sensitivity, and fat oxidation in young non-obese adults?"
This study is a randomized, three period, six sequence, single dose crossover design with ABBV-CLS-7262 in healthy adult subjects.
The current study is a placebo-controlled, double-blind, randomized controlled study using a cross-over design, including Healthy Controls (HC) and participants with Panic Disorder (PD). The primary aim of the study is to investigate the neural correlates and behavioral effects of caffeine (versus placebo), and its impact on emotional reactivity, decision-making, and interoception, and compare the effects in individuals with PD vs HCs. Subjective anxiety and the occurrence of panic attacks will also be measured. Multimodal neuroimaging methods, such as structural and functional MRI, will be used to address the aims of the study. Emotional reactivity, emotional decision-making and interoception will be measured with experimental tasks in a 7 Tesla (7T) magnetic resonance (MR) scanner, jointly with measures of skin conductance, heart rate, respiratory rate, and self-reported ratings of anxiety and interoception. Emotional reactivity will be assessed using emotional and neutral faces. Emotional decision-making will be assessed with an approach-avoidance conflict task. Changes in interoception (bodily sensation, such as pulse and respiration) will be explored using a task in which participants are asked to focus on their breathing or an external stimulus. Caffeine effects on brain resting-state activity will also be assessed. All tasks will be conducted while in the 7T MR scanner. A secondary aim of the study is to examine the impact of genetic variability in the adenosine A2A receptor (ADORA2A) genotype (e.g., rs5751876 T/T) on the effects of caffeine (vs placebo), as ADORA2A genotype has previously been associated with elevated caffeine-induced anxiety.
