Filter by:This trial in healthy subjects will assess PUR118's effect on attenuating ozone induced airway inflammation. This trial will establish the tolerability of PUR118 in healthy normal volunteers.
This trial is conducted in Europe and the United States of America (USA). The aim of the trial is to investigate the safety and tolerability of NNC0114-0006 in subjects with systemic lupus erythematosus (SLE) concomitantly treated with stable background therapies.
The main objective of this work is to conduct a clinical trial in obese and non-obese individuals testing the ability of low-fat dairy yogurt to improve gastrointestinal health and reduce chronic inflammation. Our central hypothesis is that short and long-term consumption of low-fat dairy yogurt will reduce inflammation to a greater extent in obese individuals by improving intestinal barrier function.

To investigate the difference of neutrophil apoptosis in exudative PE between TB pleurisy and non-TB pleurisy 3. To investigate the change of apoptosis pattern of PE neutrophil, before and after TB antigen stimulation, and compare the difference between TB pleurisy and non-TB pleurisy 4. To investigate diagnostic aid of the inflammation/apoptosis-associated markers and apoptosis pattern of PE neutrophil for tuberculous pleurisy
Overweight and obesity, which afflicts ~65% of the U.S. population and more than 1 billion people worldwide, increases the risk of developing hypertension. Activation of the renin angiotensin system (RAS) is an important mechanism by which obesity leads to hypertension. In addition to its vasoconstricting and sodium retaining actions, angiotensin II also has potent pro-inflammatory actions including macrophage infiltration and expression of proinflammatory cytokines in target tissues. Adipose tissue and skeletal muscle appear to be a key sites for the generation of proinflammatory cytokines. Although angiotensin II receptor blockade reduces inflammation in many tissues, the effects on adipose tissue and skeletal muscle in humans are not clear. Importantly, the chronic low grade inflammatory state that accompanies obesity complicates hypertension by contributing to insulin resistance and accelerating cardiovascular disease. Therefore, the general aim of the present proposal will be to determine the influence of angiotensin II receptor blockade on adipose tissue and skeletal muscle inflammation and its relation to improvements in insulin sensitivity, if observed, in obese hypertensive humans. To address these aims, 44 obese (BMI>30 kg/m2) hypertensive (BP>140 systolic and/or 90 diastolic) individuals (age=50-65 years) will be randomized to receive 8 weeks of either the angiotensin II receptor antagonist, olmesartan medoxomil, or no treatment in a crossover manner. Subcutaneous adipose tissue and skeletal muscle biopsies will be obtained and insulin sensitivity (intravenous glucose tolerance tests) will be assessed at baseline and following 8 weeks of each intervention. A two week washout period will separate the interventions.
The treatment of osteoarthritis, a disease that eventually affects the majority of the older population, involves the alleviation of symptoms such as pain and stiffness, and the reduction of inflammation. A double-blind, placebo-controlled, crossover study will be performed to examine the effect of topical application of Elmore Oil, a herbal remedy (containing Eucalyptus oil, Tea tree oil, Olive oil and Vanilla), which has recently been reported to have anti-inflammatory properties, on the symptoms of osteoarthritis.
A common starting dose of glucosamine and chondroitin will reduce inflammation as reflected by a reduction in serum C-reactive protein.
Background: - The immune system contains several different types of cells in the blood and other parts of the body. The body can fight infections well with the right balance of these cell types. The wrong balance of cell types may cause diseases, such as allergies or asthma. The COX-2 gene may help decide the balance of cell types that the body makes as part of the immune system. It may also play a role in certain immune system diseases. Researchers want to see how COX-2 affects the cells in the immune system. Objectives: - To study how the COX-2 gene works in the body s immune system. Eligibility: - Individuals 18 years of age and above who are part of the Environmental Polymorphisms Registry. Design: - Participants will have one study visit at the National Institutes of Health. They will collect a urine sample at home on the morning of the study visit. - Participants will have a physical exam and medical history. They will provide a blood sample. They will also give researchers the urine sample they collected that morning. - No treatment will be provided as part of this study.
The investigators hope to learn about the effects of whole grapes, in the form of freeze-dried grape powder, on markers of health. Phytochemical rich food consumption is associated with protection against chronic diseases such as cardiovascular disease (CVD) demonstrating the ability to modify endothelial function and lipemia, but exact causal mechanisms are still not well understood. The investigators will examine metabolic and mechanistic effects of consumption of whole grape powder in chronic as well as acute settings in response to meal challenges by testing blood samples to determine if markers of health have improved. The central hypothesis of this project is that consumption of grapes in the form of a polyphenol-rich freeze-dried whole grape powder (WGP) will attenuate chronic and meal induced oxidative stress and inflammatory responses in obese individuals.
Depressive disorders occur at a high rate in patients with inflammatory disorders, with a point prevalence of 15-29%, which is two to three times greater than that observed in the general population. Substantial evidence has shown that inflammation and increases in proinflammatory cytokine activity play a critical role in the onset and perpetuation of depression and depressive symptoms (e.g. insomnia, fatigue) in those who are co-morbid for inflammatory disorders. Consistent with this, experimental work has shown that an inflammatory challenge can increase depressed mood in an otherwise healthy sample. Based on these findings, there has been a growing interest in whether inflammatory processes can contribute to depression in a causal manner and how these effects might occur. Given the observation that inflammatory processes trigger social withdrawal, coupled with evidence that feelings of 'social disconnection' play a critical role in the onset and perpetuation of (non-inflammatory forms of) depression, it is surprising that the social psychological consequences of inflammation and their contribution to depression have not been more fully explored. Here, we suggest that inflammation may increase feelings of social disconnection and that these social psychological changes may be an important contributor to inflammation-associated depression. Indeed, preliminary data demonstrated that an experimentally-induced inflammatory challenge (endotoxin) led to increases in self-reported feelings of social disconnection (e.g., "I feel disconnected from others") in addition to increases in depressed mood. Aside from these findings, however, there are no studies that have explored the effect of inflammatory processes on social experience in humans. The over-arching objective of this proposal is to explore the experiential and neural correlates of inflammatory-induced changes in social experience (e.g., feelings of social disconnection), which may provide a critical missing link in understanding the relationship between inflammation and depression. Participants (n=100) will be randomly assigned to receive either endotoxin or placebo and will then be monitored for the next six hours. Blood draws to assess cytokine levels as well as self-reported feelings of social disconnection and depressed mood will be collected hourly. In addition, at the time of peak cytokine response, participants will complete a neuroimaging session to examine the effect of inflammatory challenge on neural sensitivity to social rejection and social acceptance. It is hypothesized that endotoxin will increase feelings of social disconnection over time, and that the underlying neural sensitivities that give rise to these feelings (e.g., increased neural sensitivity to social rejection; decreased neural sensitivity to social acceptance) will contribute to inflammatory-induced depressed mood.
