Unveiling the Crucial Nexus: Mitochondrial Quality Control as a Central Driver in Metabolic Dysfunction‐Associated Steatotic Liver Disease Pathogenesis

Cell Proliferation, EarlyView.
Mitochondrial quality control (MQC) impairment plays a central role in driving the pathogenesis of metabolism‐associated steatotic liver disease (MASLD). Specifically, this is manifested as reduced mitophagy; increased mitochondrial fission and decreased fusion; and impaired mitochondrial biogenesis.

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

Groundwater Monitoring &Remediation, EarlyView.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.
