Endothelium‐ and epithelium‐derived novel endogenous catecholamines as modulators of the autonomic nervous system

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 15, Page 4091-4110, August 2026.
Abstract Catecholamines are classically viewed as neuronal transmitters and adrenal hormones; however, accumulating evidence demonstrates that sources other than nerve fibres and adrenal medulla play a fundamental role in local organ regulation. Physiological paradoxes, such as preserved organ function after denervation or transplantation, challenge a ...

Diagnosis of Growth Hormone Deficiency in Children: Comparative Performance of Arginine Versus Glucagon as the First Stimulation Test

open access: yesClinical Endocrinology, Volume 105, Issue 2, Page 213-219, August 2026.
ABSTRACT Objective Growth hormone deficiency (GHD) diagnosis typically requires the performance of two sequential stimulation tests. Glucagon stimulation test (GST) and arginine stimulation test (AST) are widely used. This study aimed to determine the most suitable order of tests.

Contrast Agents for Enhanced Bioimaging: A Comprehensive Review

open access: yesChemBioChem, Volume 27, Issue 13, 14 July 2026.
Contrast agents, especially those that are nanoparticle‐based, are revolutionizing bioimaging by enabling highly sensitive, specific, and early‐stage diagnosis of diseases like cancer, using clinical imaging modalities such as CT, MRI, PET, and SPECT.

Bridging Stability and Reactivity: Novel Dinucleating Ligand With Rigid Backbone Stabilizes a Cu2O2 Side‐On Peroxido Structure

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 19, 2 July 2026.
The herein‐developed tyrosinase model complex enables the transfer of tyrosinase‐like catalytic oxygenation activity into artificial systems. Therefore, it enables the use of molecular oxygen for oxygenation and oxidation of phenolic substrates at room temperature.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

open access: yesAdvanced Science, Volume 13, Issue 37, 3 July 2026.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...
