Induction of muscle thermogenesis by high-fat diet in mice: association with obesity-resistance.

The obesogenic effect of a high-fat (HF) diet is counterbalanced by stimulation of energy expenditure and lipid oxidation in response to a meal. The aim of this study was to reveal whether muscle nonshivering thermogenesis could be stimulated by a HF diet, especially in obesity-resistant A/J compared with obesity-prone C57BL/6J (B/6J) mice. Experiments were performed on male mice born and maintained at 30 degrees C.

Creatine kinase binds more firmly to the M-band of rabbit skeletal muscle myofibrils in the presence of its substrates.

Whole body exposure to low frequency magnetic field: no provable effects on the cellular energetics of rat skeletal muscle.

On the basis of previous experience with biological effects of electromagnetic fields a potential effect of homogeneous sinusoidal magnetic field (50 Hz, 10 mT) on energy state of rat skeletal muscle was investigated. Two different total body exposures to magnetic field were selected: (1) repeated 1 hour exposure, 2 times a week for 3 months, and (2) acute 1.5 hour exposure (and the appropriate control groups).
