Muscle fiber-type specific expression of UCP3-protein is reported here for the firts time, using immunofluorescence microscopy

Recently, a role for uncoupling protein-3 (UCP3) in carbohydrate metabolism and in type 2 diabetes has been suggested. Mice overexpressing UCP3 in skeletal muscle showed reduced fasting plasma glucose levels, improved glucose tolerance after an oral glucose load, and reduced fasting plasma insulin levels. …

This letter to the editor argues that the assumption of a single value for the acetate recovery factor in carbon-13 stable isotope research for different individuals, can lead to significant errors in the outcomes of substrate utilization measurements.

Review of the effects of physical activity on insulin sensitivity

Proefschrift dat onder andere een tweejarig interventie-onderzoek beschrijft naar het effect van een bewegingsprogramma bij personen met type 2 diabetes.

Immunofluorescence microscopy in this study shows that GLUT-4 protein expression is fibre-type specific within a muscle. It is postulated that both fibre-type-dependent and fibre-type-independent factors affect GLUT-4 expression.

The data of this study indicate that the acetate recovery factor, used in stable isotope research, needs to be deteremined in every subject, under similar conditions as used for the tracer-derived determination of substrate oxidation.

This research article shows that a high intensity exercise program compared to a low intensity exercise program of the same session duration and frequency, increases insulin sensitivity to a larger extend in healthy subjects. It also shows that the short insulin tolerance test can be used to detect differences …
