Greater oxidation of dietary linoleate compared to palmitate in humans following an acute high-carbohydrate diet.

Background: We have previously demonstrated that dietary saturated fatty acids (SFA), when compared to polyunsaturated fatty acids (PUFA), are preferentially partitioned into oxidation pathways. However, it remains unclear if this preferential handling is maintained when hepatocellular metabolism is shifted toward fatty acid (FA) esterification and away from oxidation, such as when hepatic de novo lipogenesis (DNL) is upregulated.

Aim: To investigate whether an acute upregulation of hepatic DNL influences dietary FA partitioning into oxidation pathways.

Mechanical and optical investigation of dynamic behavior of violins at modal frequencies.

Two main aims of our investigation are to show differences in natural vibrations between two violins that differ in the thickness of the back plate and to determine whether they are linear systems. Two experiments were performed on the top and back plates. The first experiment was a mechanical modal analysis in a version with a fixed response point.
