The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

FEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Effect of annealing heat treatment on the microstructure and mechanical properties of laser directed energy deposited CrMnFeCoNi high entropy alloy

Journal of Materials Research and Technology
In this study, a thin-wall build of CrMnFeCoNi high entropy alloy (HEA) was fabricated by laser directed energy deposition (LDED) process. The effect of high-temperature annealing heat treatment at 1000 °C on the microstructure and mechanical properties ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Cryogenic cooling-based sustainable machining

, 2020
Machinability is the most important indicator to measure the performance of any machining operation. Cutting force, surface roughness, tool wear, dimensional accuracy, and cutting temperature, etc. are the most important machinability indicators. Various

Effect of electro discharge machining (EDM) on the AISI316L SS white layer microstructure and corrosion resistance [PDF]

, 2013
The localised corrosion resistance of austenitic stainless steels is strongly influenced by the quality of finished surface. EDM machining induces substantial changes by the high thermal gradients generated by electric sparks.
