Adsorption potential of CuO-embedded chitosan bead for the removal of acid blue 25 dye

Ain Shams Engineering Journal
Anthraquinone-based anionic dyes like acid blue 25 (AB25) are among the problematic class of pollutants in wastewaters that are detrimental to human health and aquatic organisms.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

FEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

RGBfast – A user-friendly version of the Red-Green-Blue model for assessing greenness and whiteness of analytical methods

Green Analytical Chemistry
A new version of the popular RGB model has been developed to meet the expectations of users of greenness and whiteness assessment metrics. It has been called “RGBfast” due to its simplicity and significant assessment automation. The criteria were limited

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS 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 ...

Triggering redox activity in a thiophene compound: radical stabilization and coordination chemistry [PDF]

, 2006
The synthesis, metalation, and redox properties of an acyclic bis(iminothienyl)methene L− are presented. This π-conjugated anion displays pronounced redox activity, undergoing facile one-electron oxidation to the acyclic, metal-free, neutral radical L ...

Eco-friendly HPLC method by using response surface design to measure a combination of three antidiabetic drugs

Reviews in Analytical Chemistry, 2023
In recent years, there has been a significant increase in the application of green chemistry principles in analytical chemistry. One of the key factors affecting the environmental sustainability of analytical methods is the choice of solvent.

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

FEBS 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 ...

Multiple paths of deuterium fractionation in protoplanetary disks

, 2018
We investigate deuterium chemistry coupled with the nuclear spin-state chemistry of H$_2$ and H$_3^+$ in protoplanetary disks. Multiple paths of deuterium fractionation are found; exchange reactions with D atoms, such as HCO$^+$ + D, are effective in ...

Photometric detection in flow analysis systems using integrated PEDDs [PDF]

, 2005
A novel inexpensive optical-sensing technique has been developed for colorimetric flow analysis. This sensing system employs two LEDs whereby one is used as the light source and the other as a light detector.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS 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 ...
