Filter by:The investigators have hypothesized that dietary flavonoids reduce insulin resistance and subclinical inflammation secondary to reductions in intestinal inflammation and permeability and that these events are mediated through alterations in gut microbiota composition. To test this hypothesis, 30 overweight/obese men and women will be provided two well-controlled diets that are identical in macronutrient content (Protein, 17% en; Fat, 30% en; Carbohydrate, 53% en), but differ markedly in flavonoid content (Low Flavonoid Diet, 10 mg/1000 Kcals; High Flavonoid Diet, 340 mg/1000 Kcals). All meals for both diets will be prepared and fed for 6 weeks each in a randomized cross-over design with endpoints determined in duplicate during the last week of each diet period.
Background: Researchers want to better understand the body s immune response to calorie restriction. To do this, they are asking healthy volunteers to fast for 24 hours. Researchers will test immune response before and after fasting. Objectives: To explore the benefits of calorie restriction on immune health. Eligibility: Healthy volunteers ages 21 to 37 with a body mass index between 22 and 29. Design: Participants will be screened with medical history, physical exam, and blood tests. Participants will visit NIH after an overnight fast. Their baseline immune response will be taken. They will give blood and urine samples. Then they will be given breakfast. This visit will take about 2 hours. Participants will fast (not eat or drink anything except water) for the next 24 hours. They will return to NIH the next morning. Their immune response will be taken. They will give blood and urine samples. Then they will be given breakfast. Their immune response will be taken 3 hours later. They will give a blood sample. This visit will take about 4 hours.
The aim is to test if serum level of myokines are associated with protein energy wasting, inflammation and atherosclerotic vascular disease among Taiwanese dialysis patients. Some novel myokines levels, anthropometric parameters, cardiovascular risk factors, and presence of endothelial dysfunction will be examined in 250 subjects. The distribution of some recently identified myokines such as irisin, myotatin etc levels will be studied and correlated markers of malnutrition, endothelial dysfunction, inflammation and insulin resistance. In the present study, the investigators will further follow and investigate whether serum myokines levels are associated with long-term mortality from all causes and from cardiovascular disease.
This study will determine the effects of supplementing beta-hydroxy-beta-methylbutyrate (HMB) on body composition and strength changes during weight loss. When overweight and obese persons lose weight, and in particular in conjunction with dietary restrictions, muscle, bone mass, and muscle strength are also lost. HMB has been shown to preserve muscle mass and strength, and it is thought that HMB may also preserve muscle, bone, and strength during weight-loss.
The objective of this study is to elucidate the relationship between inflammation and lipoprotein atherogenicity, and to determine the relative contribution of inflammation and lipids to CV risk in RA. The central hypothesis of this study is that inflammation and lipoprotein atherogenicity is tightly linked such that both factors are important to assess CV risk in RA. Further, the investigators hypothesize that this relationship is obscured by a consideration of routine lipids alone.
Raisins contain a significant amount of dietary fiber and polyphenolic compounds that represent an important substrate for microbiota fermentation which generates potentially beneficial end products, such as short-chain fatty acids. The mammalian gut contains a phylogenetically as well as functionally diverse microbiota that contributes to host physiology. To date, little is known about how increased raisin intake affects human gut microbiota composition. This research study will assess the effects of adding raisins to the diet of healthy adults on the bacteria from feces of human subjects and resulting self-reported GI symptoms as well as markers of immune function. The hypothesis is that by adding raisins to the diet this will result in changes in gut microbiota. Furthermore, the changes in microbiota will largely be beneficial, as evaluated by an increase in butyrate producers and bacteria associated with anti-inflammatory properties.
The investigators want to find a better way to predict the risk of having fatty tissue inflammation by using a different approach to finding out body fat composition. In this study, the investigators want to estimate the body fat composition using a DEXA scan. DEXA stands for dual energy X-ray absorptiometry. It is the standard and established test to determine bone mineral density (how strong the bones are) to diagnose osteoporosis. This test can also be used to determine the body composition including percent body fat and lean mass. The investigators will compare the participants DEXA scan results for body fat composition to the inflammation found in the breast tissue from the mastectomy to see if there is a relationship. If successful, this may help us predict which patients may be at risk for breast cancer in the future. In addition, the investigators will compare the participants DEXA scan results for body fat composition and inflammation found in the fat tissue from the mastectomy or prostatectomy to the level of exercise activity as measured by a short questionnaire to see if there is a relationship. The investigators will also measure the participants waist to hip ratio. Finally, at the time the participant has blood drawn for their standard presurgical testing, the investigators will also test the blood for prediabetes using a blood test called hemoglocin A1c. The investigators will also measure for the participants waist to hip ratio, and a Hgb A1c blood drawn will be take at the time of presurgical testing. If not feasible, Hgb A1c can be drawn at a separate visit prior to the DEXA scan. If successful, this may help us predict which patients may be at risk for breast cancer in the future.
The purpose of this study is: - To see if polyTregs can reduce inflammation in a transplanted kidney. - To find out what effects, good or bad, polyTregs will have in the kidney recipient. - To find out what effects, good or bad, taking everolimus after polyTregs will have in the kidney recipient.
The purpose of this study is to define the natural history and causes of chronic critical illness (CCI) in surgical intensive care patients who have had sepsis. The investigator wants to study a sub-population of sepsis patients that have intra-abdominal sepsis. The purpose of this research study is to define the acute changes in frailty (weakness, slowness, loss of muscle mass), comorbidity (medical problems) and disability (difficulty with mobility and performing routine daily functions) after having an infection that is located in the abdominal cavity or torso. The investigator believes having severe infection contributes to acute and permanent changes in these areas, especially in those of advanced age.
This study is to evaluate the effects of preoperative carbohydrate intake on perioperative neuroinflammation and development of delirium.
