Reactivity of Imidazole‐ and Pyridine‐Carboxaldehydes for Gem‐Diol and Hemiacetal Generation: Theoretical and Experimental Insights

open access: yesChemistryOpen, Volume 14, Issue 8, August 2025.
The generation of the gem‐diol and hemiacetal forms using pyridine‐ and imidazole‐carboxaldehyde isomers in different chemical environments was studied by NMR spectra and combined with theoretical calculations. Unlike aprotic solvents, protic ones, as water and methanol, favored the generation of the gem‐diol and hemiacetal structures.

Gill evolution in Neotropical electric fishes: Comparative phylogenetic evidence for hypoxia‐driven adaptation

open access: yesFunctional Ecology, Volume 39, Issue 8, Page 1940-1956, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tropical freshwater fishes are often exposed to hypoxia, which limits aerobic metabolism and drives the evolution of diverse physiological, behavioural and morphological adaptations.

Caveolin‐1 Regulates Parathyroid Hormone (PTH)‐Related Protein (PTHrP) Actions on PTH Receptor Type 1 in Bone Cells

open access: yesJournal of Cellular Physiology, Volume 240, Issue 7, July 2025.
Caveolin1 interacts with PTH1R at membrane‐bound microdomains delaying receptor internalization, promoting cAMP signaling over calcium and ERK1/2 kinase pathways, and regulating bone formation and bone remodeling gene expression upon agonist stimulation in osteoblastic cells.

Quantification of Lateralized Overgrowth and Genotype‐Driven Tissue Composition

open access: yesClinical Genetics, Volume 108, Issue 1, Page 49-57, July 2025.
Lateralized overgrowth involves asymmetric body growth across conditions. TB‐DXA accurately identifies and quantifies tissue overgrowth, showing varied patterns among conditions and improving diagnosis. ABSTRACT Lateralized overgrowth (LO) is characterized by excessive growth of one side of the body compared to the other.
