NCT02458586
Epidemiological data and studies in animal models suggest, that polyunsatured fatty acids (PUFA) rather than mono-unsatured fatty acids (MUFA) are associated with lower hepatic lipid content (HCL) and may facilitate a decrease of HCL in case of non-alcoholic fatty liver disease (NAFLD). The investigators therefore conduct an interventional trial in subjects with normal glucose metabolism, but increased HCL, fulfilling criteria for NAFLD. The study will compare two dietary interventions in parallel design, one containing mainly PUFA (canola oil), one containing only MUFA (olive oil). The intervention of 8 weeks is accomodated by dietary counseling. Metabolic outcome variables will be assessed with MR spectroscopy (liver fat) and euglycemic hepatic clamp (glucose metabolism/insulin sensitivity).
NCT00495599
The central hypothesis of our study is that metabolic and hemodynamic improvements following gastric bypass surgery are mediated by downregulation of inflammation-related adipokines produced by the intra-abdominal adipose tissue such as Visfatin.

In the developing countries, obesity prevalence is on a dramatic rise. Obesity is related to co-morbidities and as a result, obesity significantly shortens life expectancy and lowers quality of life. To prevent this, participation in exercise or training programs is absolutely necessary, in order to generate adipose tissue mass loss. The amount of adipose tissue mass loss is, amongst others, dependent on lipolysis which is under endocrine regulation by, mainly, catecholamines, insulin and atrial natriuretic peptide. However, large variations in adipose tissue mass loss and gain are likely in obese subjects, possibly due to a decreased lipolytic effect of these hormones (as was shown for catecholamines in the subcutaneous adipose tissue of obese subjects). However, the relative contribution of atrial natriuretic peptide in the lipolytic process remains elusive, particularly in subjects with obesity, which show an increased plasma expression of atrial natriuretic peptide. The aim of the present study is to observe the contribution of atrial natriuretic peptide in the subcutaneous adipose tissue of obese subjects. This will be tested by measurements of extracellular glycerol levels (by microdialysis) in the subcutaneous adipose tissue in situ at rest and during endurance exercise under local beta- and alpha-blockade. Eventually, the knowledge gained from this research will contribute to the optimization of exercise programs for people with obesity.
