Colocalization of Dopamine D1 and D2 Receptors With Neuronal Nitric Oxide Synthase in the Rat Paraventricular Nucleus: A Structural Basis for Dopaminergic–Nitrergic Interaction

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 4, July 2026.
ABSTRACT The paraventricular nucleus (PVN) plays a central role in neuroendocrine and autonomic regulation, including male sexual behaviour. Dopaminergic and nitrergic signalling within the PVN are functionally linked, but their cellular relationship remains unclear.

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

open access: yesNew Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

The Complex Relation of Branched‐Chain Amino Acids and Inflammation in the Obesity and Diabetes Context

open access: yesObesity Reviews, Volume 27, Issue 7, July 2026.
ABSTRACT In a scenario with increasing cases of obesity and diabetes worldwide, branched‐chain amino acids (BCAA) metabolism has become an important factor in the understanding of these pathologies. More recently, its chronic high plasma levels have been postulated, alongside glucose, inflammatory factors, and other molecules, as an important ...

Disruption of Asparagine Synthetase Is Associated to Increased Biomass in Lotus japonicus

open access: yesPlant Biotechnology Journal, Volume 24, Issue 7, Page 4471-4483, July 2026.
ABSTRACT Asparagine (Asn) constitutes the major form of nitrogen translocated within Lotus japonicus plants. In this work we use knock‐out (KO) LORE1 mutants‐deficient in the asparagine synthetase gene (LjASN1), which is the most highly expressed ASN gene in plants grown under non‐symbiotic (NS) conditions, but much less expressed under symbiotic (S ...

Identifying the Thermodynamic Driving Force of Metal Extraction by Hydrophobic Eutectic Solvents

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
Solvent extraction (SX) in hydrophobic eutectic solvent (HES) appears as an extension rather than a “revolution” of SX in common organic diluents for a given neutral extractant. A detailed thermodynamic and spectroscopic study shows that SX in HES imposes an enthalpic penalty but lowers the entropy cost of Eu3+ transfer, leading to enhanced metal ...
