Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

The Efficacy of Calcium Carbonate Scale Inhibition by Commercial Polymer Scale Inhibitors

open access: yesChemical Engineering Transactions, 2015
The efficacy of calcium carbonate scale inhibition by three selected inhibitors, Polymaleic Acid (PMA), Polyamino Polyether Methylene Phosphonic Acid (PAPEMP) and Acrylic Acid-Maleic Anhydride (AA/MA) copolymer was investigated via static beaker tests at

The effects of strigolactones on some biochemical traits in calcified media on grapevine

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2022
Plants are stressed in different ways when they are in environments unsuitable for them. Among these stresses, abiotic factors are common. Calcified soil is also a stress factor.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Calcium phosphate crystal forms in human jaw bones of changed osteoporotic structure [PDF]

open access: yesStomatološki glasnik Srbije, 2011
Introduction. Calcium phosphates are chemical compounds that can be found in various forms within nature, as well as in human jaws and bones. The aim of this study was to assess the structure of solid chemical compounds which form the structure of ...
