Role of Divalent Cations in HIV-1 Replication and Pathogenicity

Viruses, 2020
Divalent cations are essential for life and are fundamentally important coordinators of cellular metabolism, cell growth, host-pathogen interactions, and cell death.

Translational Entropy-Driven Competitive and Additive Effects on DNA Higher-Order Structure via Ion Exchange Between Cations of Different Valencies [PDF]

Entropy
DNA conformational transitions in aqueous environments are strongly influenced by electrostatic interactions with surrounding cations. This review/perspective article summarizes the experimental findings reported during the last decade on the competitive/

Divalent metal cations stimulate skeleton interoception for new bone formation in mouse injury models

Nature Communications, 2022
Mechanisms underlying bone formation induced by divalent metal cations remain largely unknown. Here the authors show that these cations can activate the skeleton interoceptive circuit through the immune-neural axis to initiate new bone formation.

Study on the Process of Intermolecular Forces and Electrostatic Force Between Cations and Nano-SiO₂ Based on Molecular Simulation [PDF]

Molecules
Although low-permeability oil reservoirs boast abundant resources, oil recovery remains relatively low due to the limitations of current water flooding development technology in oilfields.

A combined PIE-FRET and FCS assay to monitor RNA dynamics and cleavage by SARS-CoV-2 Nsp15 [PDF]

Scientific Reports
Nsp15 is an endoribonuclease, highly conserved among coronaviruses, that helps the virus evade detection in host cells by cleaving uridine-rich viral RNA sequences. Those sequences would otherwise trigger immune response pathways.

High silica concentration in RO concentrate

Water Resources and Industry, 2022
Silica scaling is one of the major scaling challenges in Reverse Osmosis (RO). The safe operation practice is to keep the silica concentration below 150 mg/L in RO concentrate.

Identification of a putative kinase interacting domain in the durum wheat catalase 1 (TdCAT1) protein

Heliyon, 2023
Catalases are crucial antioxidant enzymes that regulate plants responses to different biotic and abiotic stresses. It has been previously shown that the activities of durum wheat catalase proteins (TdCAT1) were stimulated in the presence of divalent ...

A Selective Separation Mechanism for Mono/divalent Cations and Properties of a Hollow-Fiber Composite Nanofiltration Membrane Having a Positively Charged Surface

Membranes, 2023
Positively charged nanofiltration (NF) technology is considered a green and low-cost method for mono/divalent cation separation. Nevertheless, the separation rejection mechanisms of these NF membranes have yet to be extensively investigated. In this work,

Inhibition of the prokaryotic pentameric ligand-gated ion channel ELIC by divalent cations. [PDF]

PLoS Biology, 2012
The modulation of pentameric ligand-gated ion channels (pLGICs) by divalent cations is believed to play an important role in their regulation in a physiological context.

Calcium decreases cell wall swelling in sweet cherry fruit

Scientific Reports, 2022
Swelling of epidermal cell walls decreases cell-to-cell adhesion and increases cracking susceptibility in sweet cherry. Ca is suggested to decrease cracking susceptibility by crosslinking of cell wall components and, possibly, by decreasing swelling. The
