PGC-1alpha, SIRT1 and AMPK, an energy sensing network that controls energy expenditure

PURPOSE OF REVIEW: Peroxisome proliferator-activated receptor gamma coactivator-1-alpha (PGC-1alpha) has been extensively described as a master regulator of mitochondrial biogenesis. However, PGC-1alpha activity is not constant and can be finely tuned in r ...

The Matricellular Protein Periostin Is Required for Sost Inhibition and the Anabolic Response to Mechanical Loading and Physical Activity

Vincent Stadelmann

Periostin (gene Postn) is a secreted extracellular matrix protein involved in cell recruitment and adhesion and plays an important role in odontogenesis. In bone, periostin is preferentially expressed in the periosteum, but its functional significance rema ...

Adipose-specific knockout of raptor results in lean mice with enhanced mitochondrial respiration

Johan Auwerx

raptor is a specific and essential component of mammalian TOR complex 1 (mTORC1), a key regulator of cell growth and metabolism. To investigate a role of adipose mTORC1 in regulation of adipose and whole-body metabolism, we generated mice with an adipose-s ...

Stair climbing detection during daily physical activity using a miniature gyroscope

Kamiar Aminian, Anisoara Ionescu, Bijan Najafi, Brian Coley

A new method of monitoring physical activity that is able to detect walking upstairs using a miniature gyroscope attached to the shank is presented. Wavelet transformation, in conjunction with a simple kinematics model, was used to detect toe-off, heel-str ...

Improved physical activity in patients treated for chronic pain by spinal cord stimulation

Kamiar Aminian, Anisoara Ionescu, Bijan Najafi

The objective of this study was to objectively assess the physical activity of daily living in chronic pain patients treated with spinal cord stimulation (SCS). Changes in pain and spontaneous physical activity following SCS were evaluated under real life ...

Physical activity monitoring based on accelerometry: validation and comparison with video observation

Kamiar Aminian, Philippe Robert

The objective of this feasibility study is to evaluate the use of the 'Physilog' device, an ambulatory physical- activity recorder based on acceleration measurement, for the monitoring of daily physical activities. Accelerations measured at the level of th ...

A new method for body posture detection using a kinematic sensor

Kamiar Aminian, Philippe Robert, Bijan Najafi

The objective of this study is to present a new method of physical activity monitoring, able to detect body postures (sitting, standing and lying) from only one kinematic sensor attached on the chest. Wavelet analysis in conjunction with a simple kinematic ...
