Urinary Metabolic Biomarkers of Attentional Control in Children With Attention‐Deficit/Hyperactivity Disorder: A Dimensional Approach Through 1H NMR‐Based Metabolomics

open access: yesNMR in Biomedicine, Volume 38, Issue 8, August 2025.
This study identified five attentional control subgroups in school‐aged children, with and without ADHD, using VR‐based behavioral tests. NMR metabolomics revealed subgroup‐specific urinary metabolic profiles linked to energy and amino acid metabolism.

Differences in mRNA Expression of Selected Cytochrome P450, Transporters and Nuclear Receptors Among Various Rat Models of Metabolic Syndrome

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 137, Issue 2, August 2025.
Metabolic syndrome (MetS) is a combination of several factors, which lead to a higher risk of cardiovascular and other diseases. To study MetS, its mechanisms and means to alleviate complications associated with it, there is a demand for suitable animal models and their strains.

Retinal Ganglion Cell Loss in Diabetes Associated with Elevated Homocysteine

open access: yesOphthalmology and Eye Diseases, 2009
A number of studies have suggested that homocysteine may be a contributing factor to development of retinopathy in diabetic patients based on observed correlations between elevated homocysteine levels and the presence of retinopathy.

Discrimination Factor of Sulphur Stable Isotope Ratios Between Pregnant Fin Whales and Their Foetuses

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 14, 30 July 2025.
Abstract Rationale In‐utero synthesised tissues of mammals have often been used to infer maternal behaviour during gestation. Differences in δ15N or δ13C values between foetal and maternal tissues (foetus–mother discrimination factors) are well established, but they remain uncertain for δ34S values.

Multifunctional Organelle‐Targeting Probes for Intracellular Imaging and Enhanced Cancer Phototherapy

open access: yesChemistry – A European Journal, Volume 31, Issue 38, July 8, 2025.
Cy‐NBD‐5F was synthesized as a responsive photodynamic theranostic agent, featuring GSH‐activated fluorescence signaling and enhanced Type‐I&II PDT for effective cancer treatment. After reacting with GSH, the active compound (Cy‐OH‐5F) successfully provides NIR emission and induces cancer cell death under light irradiation.
