Active clinical trials for "Inflammation"

Respiratory viral infections cause significant illness, especially in vulnerable individuals and is a topic of immense significance during the current COVID-19 global pandemic. Respiratory diseases such as asthma involve inflammation of the airways and viruses are a major cause of asthma attacks. The nose is easier to access than the lungs but has similar cells and is therefore useful to study immune responses throughout the respiratory tract. Rather than study the effects of a live virus on the immune system, it is possible to give a component or mimic of a virus to simulate an infection in a similar but more straightforward manner, without causing disease. In this study we will use a nasal spray containing a sterile substance called Resiquimod (also called R848) to mimic a viral infection. Resiquimod does not contain any living organisms and therefore there is no possibility of developing a real infection. Resiquimod works by binding to receptors in cells that line the inside of the nose (epithelial cells) as well as cells that can fight infection (immune cells). These cells respond to Resiquimod and cause mild inflammation in the nose, similar to a mild cold. We can then take samples to measure this response and investigate how it differs between individuals. This will help us better understand how the human immune system responds to viruses, and which cells and molecules the body uses to defend itself against infection.

This study explores the effects of probiotic administration on the outcomes of surgical treatment, and also on the state of the intestinal microbiota and the intestinal barrier. The study protocol is designed as a randomized double-blind placebo-controlled clinical trial. Patients qualified for bariatric surgery will be randomized to receive probiotics or a placebo for 12 weeks. Researchers are going to evaluate changes in intestinal microbiota, epithelial permeability, weight loss, postoperative complications, and serum parameters reflecting inflammation, metabolic profile, and metabolic endotoxemia.

The purpose of this study is to determine if vinegar ingestion promotes beneficial changes to metabolic health parameters in healthy, overweight adults.

Cow's milk contains two types of β-casein: A1 and A2. It is evident from human clinical trials that milk with A1 protein produces more hydrogen and symptoms of lactose intolerance. A pro-inflammatory μ-opioid peptide BCM-7 is released from A1 but not from A2. Milk containing A1 β-casein produced more inflammatory markers than A2 β-casein. This is a double-blinded, randomized, controlled trial conducted to determine if A1 beta-casein containing milk causes acute effects on inflammatory markers following a single milk feeding, as compared to milk containing only A2 beta-casein.

The purpose of this study is to answer: how do inflammation and anti-inflammatory skin therapies work in the skin? Inflammation is a protective response from the body's immune system to injury, disease, or irritation. It is a process by which your body's white blood cells and the things they make protect you from infection from outside invaders such as bacteria and viruses.

Population aging worldwide has increased substantially in recent years. In order to prevent disabling diseases and improve the quality of life, it is necessary to understand the conditions related to the health of this specific population. One of the known alterations that occur in the body is the increased low-grade systemic inflammatory process, anabolic resistance, and muscle catabolism. These conditions can negatively interfere with muscle quality and functionality. However, the maintenance of the metabolic and physical functionality of muscle tissue can be preserved by performing physical exercises throughout life because of its anti-inflammatory mechanisms. In the present study, a multicomponent training program that combines aerobic, strength, balance, and flexibility capacities was used. The hypothesis is that performing this type of physical exercise will mitigate meta-inflammation and its negative effects, in addition to stimulating anabolic signals and reducing insulin resistance present in anabolic resistance, leading to improved quality and muscle functionality in elderly women with obesity.

The purpose of this research is to determine the role of a type of immune cell in blood, called a non-classical monocytes (NCMs), following consumption of a high-fat meal. Previous studies have found that monocytes are important for blood vessel health. In this study, two different high-fat meals will be used to study the effect of different types of dietary fat on postprandial NCMs. The investigators will characterize NCMs in both fasting conditions and following consumption of two different high-fat meals, and will evaluate whether the type of fat in a meal affects NCMs in blood.

This study will determine if ingesting a beet-based supplement with nitrates for 2 weeks moderates exercise-induced inflammation.

It is observed that replacing meat with protein-rich plant-based food products are associated with lower mortality and obesity prevention. Sources of plant proteins typically undergo several processing and refinement procedures to improve the taste and digestibility of plant-based food products. These procedures alter the chemical composition, which can impact the nutritional quality of the processed food. It is not known what is the impact of processed products on human metabolism and intestinal microbiota. Therefore, the impact of a set of plant-based protein-rich food products with varying degree of processing on the composition and function of human gut microbiome and metabolism will be assessed in a clinical intervention

The goal of this study is to examine how whole-body hyperthermia affects the thermoinflammatory profile, which includes the combined immune and heat shock response, in patients with depression and whether these changes correlate with decreased depression in individuals with Major Depressive Disorder.
