Intracellular Ca(2+) signaling: A novel player in the canonical mTOR-controlled autophagy pathway.

Communicative & integrative biology

Decuypere JP, Paudel RC, Parys J, Bultynck G.
PMID: 24265855
Commun Integr Biol. 2013 Sep 01;6(5):e25429. doi: 10.4161/cib.25429. Epub 2013 Jun 25.

Functional intracellular Ca(2+) signaling is essential for the upregulation of the canonical mTOR-controlled autophagy pathway triggered by rapamycin or by nutrient deprivation. Moreover, modifications in the Ca(2+)-signaling machinery coincide with autophagy stimulation. This results in enhanced intracellular Ca(2+) signaling...

The analysis of individual biological nanoparticles has significantly advanced our understanding of fundamental biological processes but is also rapidly becoming relevant for molecular diagnostic applications in the emerging field of personalized medicine. Both optical and electrical methods for the...

Fast spatially resolved exhaust gas recirculation (EGR) distribution measurements in an internal combustion engine using absorption spectroscopy.

Applied spectroscopy

Appl Spectrosc. 2015 Sep;69(9):1047-58. doi: 10.1366/14-07796. Epub 2015 Aug 06.

Exhaust gas recirculation (EGR) in internal combustion engines is an effective method of reducing NOx emissions while improving efficiency. However, insufficient mixing between fresh air and exhaust gas can lead to cycle-to-cycle and cylinder-to-cylinder non-uniform charge gas mixtures of...
