Filter by:This randomized crossover trial (RCT) investigates the acute effect (over a 6-hour period) of a meal containing varying serving sizes (doses) of freeze-dried oyster mushroom powder, on the cognitive behaviour and markers of metabolism and inflammation related to neuronal health in healthy adults aged 60-80 years old. The study will involve a screening visit and four testing visits, with a week interval between each. During the four testing visits, cognitive-mood battery tests will be taken at baseline and then at 2-, 4- and 6-hour intervals following the consumption of the intervention meal. Also, a blood draw will be taken at the end of each testing visit day to allow the determination of inflammatory, metabolic and neuronal markers.
Fructose consumption is associated with the development of metabolic diseases and low-grade inflammation. However, the acute effect of a single meal rich in fructose on the metabolic and inflammatory response is not fully understood. This study will to evaluate the acute metabolic and inflammatory effect caused by a meal containing fructose overload. This will be a three-arm crossover, randomized, double-blind clinical trial. Participants will undergo the three interventions for random order: (i) standardized meal plus sucrose overload; (ii) standardized meal plus glucose overload; (iii) standardized meal plus fructose overload. During the washout period (7 to 21 days), the subjects will instructed to maintain their usual eating behavior and physical activity. On the day of each intervention, participants will to the outpatient clinic in the morning after an overnight fast. Anthropometric data (weight, height, and waist circumference) will collected. Body composition will evaluated using bioimpedance (Quantum® apparatus, RJM Systems, Michigan) and blood pressure and heart rate (digital monitor, model HEM705CP®, Omron) will measured after 30 minutes of rest. A catheter with a three-way stopcock will inserted into the arm of the volunteers. Blood samples (5mL) will collected after overnight fasting (baseline) and 30, 60, 120, and 240 minutes after the standardized meal containing sucrose or glucose or fructose overload. Participants will remain seated throughout the evaluation period. Participants will receive a standardized meal of bread, ham, and margarine plus a sweetened drink (200mL) with similar amounts of different carbohydrates (sucrose, glucose, or fructose) in each intervention. The meals will provide 25% of the energy requirements, calculated from the resting energy expenditure measured by indirect calorimetry (KORR®, MetaCheck) multiplied by the activity factor plus 10% referring to the thermal effect of food. The meal will consiste of 15% of protein, 30% of fat, and 55% of carbohydrate (30% of complex carbohydrates and 25% of sucrose or glucose or fructose). Serum levels of glucose, triglycerides, total cholesterol, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) will be measured by colorimetric enzymatic test. Serum levels of adiponectin, leptin, resistin and TNF will be measured by Enzyme Linked ImmuneSorbent Assay (ELISA). Serum levels of IL-2, IL-4, IL-5, IL-6, IL-10, IL-17, IFN-γ and eotaxin will be obtained by the Cytometric Bead Array (CBA).
The purpose of this study is to assess the effect of low-pressure pneumoperitoneum on post operative pain and inflammation in patients undergoing elective laparoscopic cholecystectomy by comparing it to standard practice.
The VINCI-AD study will investigate the impact of non-invasive vagus nerve stimulation (VNS) on memory in participants with existing mild memory impairment. VNS is a safe, existing treatment, licensed in epilepsy and depression. Until recently, stimulating the vagus nerve involved an operation (invasive VNS) but we can now perform VNS by stimulating a nerve in the outer ear with a very gentle current using a small earpiece, called transcutaneous vagus nerve stimulation (t-VNS). Previous studies have indicated that invasive VNS may improve memory in people with no cognitive issues or with dementia. No study has examined the use of t-VNS in people with diagnosed mild memory issues. The main aim of this study is to assess the feasibility of using t-VNS in participants with Mild Cognitive Impairment (MCI). Other objectives include: 1) Determining the optimal stimulation settings to improve memory; 2) Assessment of safety and tolerability of VNS in participants with memory impairment ; 3) Exploration of impact of non-invasive VNS on brain oxygenation via near-infrared spectroscopy (NIRS): 4) Assessment of impact of VNS on blood markers of inflammation: 5) Assessment of impact of VNS on heart rate variability (HRV) and orthostatic stress in participants with memory impairment. The study will enroll participants via the memory assessment service who have been diagnosed with MCI. The study will enroll 40 participants. All eligible participants will undergo three assessments; one as a baseline assessment of neurocardiovascular health, baseline cognitive tests and baseline blood tests. They will then return for two further visits, one while undergoing active stimulation (active t-VNS) and one while undergoing sham stimulation (sham t-VNS).
This is a single-center, double-blind, randomized controlled clinical trial comparing four groups: placebo conventional coronary artery bypass graft (CCABG) group, dexamethasone CCABG group, placebo off-pump coronary artery bypass (OPCAB) group, and dexamethasone OPCAB group. The primary outcomes of this study is comprised of presence of arrhythmia, major adverse cardiac events (MACE), myocardial infarction, stroke, renal failure, respiratory failure, inflammation, and death. These primary outcomes were assessed during the surgery, 18 hours post surgery, every day during the hospital stay, 14 days and 30 days post surgery.
Irisin is novel adipomyokine known as a mediator of physical activity that produced mainly by skeletal muscle and adipose tissues. It is cleaved from the fibronectin type III domain-containing protein 5 (FDNC5), which is, in turn, induced by peroxisome proliferator-activated receptor-ɣ co-activator 1-α (PGC-1α). Several studies reported that irisin is related with pathogenesis of many diseases which are known to be associated with periodontal disease such as obesity, diabetes mellitus, rheumatoid arthritis, cardiovascular disease, nonalcoholic fatty liver disease and metabolic bone diseases. There are several studies those have reported that increased IL-6 levels are associated with progression and severity of periodontitis . Recently, it has been shown that irisin is expressed in human periodontal ligament cells (hPDL), dental pulp stem cells and osteoblasts. Also, a few studies revealed that irisin promotes growth, migration and matrix formation in hPDL cells and cementoblast differentiation. To the best our knowledge, there 's one study has been reported that the higher levels of irisin in saliva in patient with chronic periodontitis
Arginine metabolites are amino acids that are associated with vascular tone regulation and the level of inflammation, with critical roles in the synthesis of NO. Our aim was to determine the ADMA, SDMA, L-NMMA, L-arginine, L-homoarginine and IL-6 levels in saliva and serum samples from periodontitis patients and periodontally healthy individuals and to assess the levels of these compounds according to smoking status and compare these levels to those of healthy individuals.
Systematic inflammation and lipid profiles are two major therapeutic targets for cardiovascular diseases. The effectiveness of vegan diet has been reported (doi: 10.3389/fnut.2022.807810). Aim: To compare the effectiveness of a nutritionally balanced vegan diet and a Myplate diet ((Taiwanese version) on systematic inflammation and lipoprotein subclass. Design: Randomized crossover design
Vigorous exercise bouts result in significant inflammation and muscle soreness. Our research group has published several papers showing that ingestion of various types of fruits enhances inflammation resolution after exercise. Mangoes have a unique nutrient profile (carotenoids, polyphenols, sugars, vitamins) that we hypothesize will mitigate post-exercise inflammation and muscle soreness. This study will examine the effect of 2 cups/day frozen mango ingestion (2 weeks, 330 g/day) in moderating exercise-induced (2.25 h cycling) inflammation and muscle soreness in a randomized crossover trial. Participants will include 20 male and female young adult cyclists (ages 18-60 years) who are capable of cycling 2.25 h in the laboratory on trainers. In random order, the cyclists will supplement their diets with 2 cups/day mangoes with 1 cup water or 1 cup water alone for two weeks, followed by the 2.25-h exercise challenge. Blood and urine samples will be collected pre- and post-2 weeks supplementation. Additional blood samples will be collected immediately post-exercise, and then 1.5-h, 3-h, and 24-h post-exercise. Urine samples will be analyzed for mango-related metabolites to confirm compliance to the supplementation regimen and to establish statistical relationships with inflammation-related outcomes. The blood samples will be analyzed for novel, cutting-edge outcomes related to inflammation including 70 oxylipins, inflammasome activation, and pro-inflammatory cytokines that we have previously shown are sensitive to exercise and nutrition-based interventions. If the data support our hypothesis, mango ingestion will be viewed as a nutritional strategy to counter exercise-induced inflammation by fitness enthusiasts and athletes who exercise vigorously on a regular basis.
Vigorous exercise can stress the body. Consuming special types of diet supplements may help the body recover better from exercise. This includes a bright red supplement called astaxanthin that is found in certain algae and causes the pink-red color in salmon. Astaxanthin is an antioxidant and may protect cells from damage and improve the way the immune system functions. The main purpose of this study is to determine if 4 weeks of consuming astaxanthin improves recovery from 2.25 hours of intensive running on a treadmill. This study will also measure whether or not astaxanthin supplementation improves skin health
