Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Improvement of Cycle Stability for Graphite-Based Lithium-Ion Batteries via Usage of Phenyl Methanesulfonate as an Electrolyte Additive

Batteries, 2022
In this work, phenyl methanesulfonate (PMS) is evaluated as an additive to enhance the cyclic stability of lithium-ion batteries (LIBs) based on a graphite electrode.

Sea level changes versus hydrothermal diagenesis: Origin of Triassic carbonate platform cycles in the Dolomites, Italy: Discussion [PDF]

In his recent paper, Blendinger (2004) presents a new and unconventional hypothesis for the formation of the Triassic Latemàr carbonate cycles. He assigned the cycles to intermittent hydrothermal influence alternating with normal marine deposition ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A pathway to cyclic carbonates: Cycloaddition of carbon dioxide to epoxidized methyl oleate on grafted heterogeneous catalysts

Journal of CO2 Utilization
The conversion of CO2 into value-added cyclic carbonates via cycloaddition to bio-derived epoxides presents a sustainable approach for CO2 utilization. However, the production of cyclic carbonates from bio-sources such as epoxidized vegetable oils (EVOs)

Using cyclic alternating water injection to enhance oil recovery for carbonate reservoirs developed by linear horizontal well pattern

Petroleum Exploration and Development, 2021
In view of high water cut and low oil recovery caused by the unidirectional flow in linear pattern of horizontal wells for the carbonate reservoirs in the Middle East, this paper provides a novel approach to improve oil recovery by converting linear ...

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

Molecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Nanoporous Copper for the Electrosynthesis of Cyclic Carbonates from CO2 and Epoxides

ChemElectroChem
Cyclic carbonates are often produced through catalytic coupling reactions of CO2 with epoxides under harsh conditions. Here, we present a highly active nanoporous copper (np‐Cu) cathode material for the electrosynthesis of cyclic carbonates in mild ...

Impact of hysteresis of relative phase permeabilities in 3D modeling of cyclic waterflooding in a carbonate reservoir

Energy Geoscience
The main task when extracting oil from waterflooded reservoirs during late development stages is enhancing the mobility of the remaining reserves. In the context of declining oil export prices, the use of chemical and gas methods for enhancing oil ...

A four-protein metabolon assembled by a small peptide protein creates the pentacyclic carbonate ring of aldgamycins

Acta Pharmaceutica Sinica B, 2021
Organic carbonates (OCs) are a class of compounds featured by a carbonyl flanked by two alkoxy/aryloxy groups. They exist in either linear or cyclic forms, of which the majority encountered in nature adopt a pentacyclic structure.
