Mitochondria are small organelles with key functions inside our cells. Unfortunately, there are a number of diseases that arise from their malfunction. To test whether they are healthy or not, complicated procedures are often required. In the paper, we applied our sensor that detects motion of living microorganisms. We saw that a sensor detecting tiny vibrations is powerful enough to sense the difference between normal and inhibited mitochondria.

The intervertebral disc is submitted to complex loading, which are responsible for variations of the hydrostatic pressure in its structure. The objective of the present work is to determine the internal pressure that promotes the porcine disc disruption. The tests were performed using a hydraulic cylinder that inflates the discs. It was concluded that potential for porcine disc injury may exist at low pressures for and the rupture could occur within intradiscal physiological pressures.
