Coarse particle flotation: A review

In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse air flow into fine bubbles.

Aims: Well-controlled mitochondrial homeostasis, including a mitochondria-specific form of autophagy (hereafter referred to as mitophagy), is essential for maintaining cardiac function. The molecular mechanism mediating mitophagy during pressure overload (PO) is poorly understood. We have shown previously that mitophagy in the heart is mediated primarily by …

Coping with the calcium overload caused by cell injury: ER …

Abstract. Cells maintain their cytosolic calcium (Ca 2+) in nanomolar range and use controlled increase in Ca 2+ for intracellular signaling. With the extracellular Ca 2+ in the millimolar range, there is a steep Ca 2+ gradient across the plasma membrane (PM). Thus, injury that damages PM, leads to a cytosolic Ca 2+ overload, which helps activate PM repair (PMR) response.
