GLS1‐Mediated Redundancy in Glutamate Accelerates Arterial Calcification via Activating NMDAR/Ca2+/β‐Catenin Pathway

open access: yesAdvanced Science, Volume 12, Issue 21, June 5, 2025.
GLS1 is a novel contributor to arterial calcification. GLS1‐catalyzed glutamate exerts the promoting effects on osteogenic reprogramming in arteries. NMDAR, a glutamate receptor, is also activated and overexpressed during arterial calcification.

Phototauntomerism of o-nitrobenzyl compounds: o-quinonoid aci-nitro species studied by matrix isolation and DFT calculations [PDF]

open access: yes, 2001
Photolyses of 2-nitrobenzyl methyl ether and 2-nitrotoluene with 254 nm light have been investigated in Ar and N2 matrices at 12 K, and have been found to give o-quinonoid aci-nitro species as the primary photoproducts, along with other products.

Estimation and Validation of an Effective Ergothioneine Dose for Improved Sleep Quality Using Physiologically Based Pharmacokinetic Model

open access: yesFood Science &Nutrition, Volume 13, Issue 6, June 2025.
We proposed a new approach to estimate the minimum efficacious doses of a food ingredient using a PBPK model. The study was conducted in two parts: Study 1 involved the optimization of the PBPK model based on plasma and blood EGT concentration profiles.

Derivatives of MOPS: promising scaffolds for SARS coronaviruses Macro domain‐targeted inhibition

open access: yesThe FEBS Journal, Volume 292, Issue 11, Page 2865-2881, June 2025.
The SARS‐CoV/CoV‐2 genome encodes non‐structural protein 3, which contains a ‘Macro domain’. This protein domain exhibits antagonistic activity against interferon signaling, which disrupts the host innate immune response and can thus mediate viral escape, highlighting its therapeutic potential.
