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

Anatomia, 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.

Co(II), Cu(II), and Ni(II) Coordination Complexes: Synthesis, Characterization, Experimental, and Computational Study on Potential Antiplasmodial Activity

ChemMedChem, Volume 21, Issue 12, 26 June 2026.
Four isostructural complexes (C1–C4) derived from 2‐(tert‐butoxy)‐6‐(1H‐imidazol‐1‐yl)pyridine with axial halides exhibit octahedral trans M(L)4X2 geometries, confirmed by X‐ray diffraction. They feature a discrete 1,6M7−1 topology, identified using ToposPro analysis.

A Systematic Comparison of Alpha‐Synuclein Seed Amplification Assays for Increasing Reproducibility

Annals of Clinical and Translational Neurology, Volume 13, Issue 6, Page 1088-1105, June 2026.
ABSTRACT Seed amplification assays (SAAs) enable ultrasensitive detection of misfolded α‐synuclein across biofluids and tissues. Yet, heterogeneity in protocols limits cross‐study comparability and clinical translation. Here, we review α‐synuclein SAA methods and their performance across various biological matrices.

Modulation of the Stress Granule Component Carhsp1 Mitigates Disease‐Associated Deficits in Spinocerebellar Ataxia Type 3 Mouse Models

Movement Disorders, Volume 41, Issue 6, Page 1516-1527, June 2026.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a polyglutamine (polyQ) neurogenerative disorder that results from CAG trinucleotide repeat expansions in the ATXN3 gene, leading to toxic protein aggregate formation and cellular pathway dysfunction.

Long‐Term Colorectal Cancer Incidence After Adenoma and Serrated Polyp Removal: Results From the Colonprev Trial

United European Gastroenterology Journal, Volume 14, Issue 5, June 2026.
ABSTRACT Background The risk of colorectal cancer (CRC) after serrated polyp resection remains unclear, and current surveillance recommendations rely on limited evidence. We evaluated CRC incidence in individuals with advanced serrated lesions (ASL) detected at baseline colonoscopy and compared risk according to the most advanced lesion identified ...
