Ethanol Infusion in the Vein of Marshall for Persistent Atrial Fibrillation Ablation: Evidence From Randomized Controlled Trials

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation (CA) for atrial fibrillation (AF), yet outcomes remain suboptimal in persistent AF patients. Ethanol infusion in the vein of Marshal (VoM), an embryological remnant implicated in AF pathogenesis, may enhance ablation efficacy.

ARF7/19 activate CRF3 in response to cold via Aux/IAA degradation

open access: yesJournal of Integrative Plant Biology, EarlyView.
Cold induces degradation of Aux/IAA proteins through the ubiquitin‐proteasome pathway, releasing AUXIN RESPONSE FACTOR7 (ARF7) and ARF19 from Aux/IAA‐mediated repression, leading to activation of CYTOKININ RESPONSE FACTOR 3 (CRF3) expression under cold stress.

Three‐dimensional quantification of oxytocin neurons in the hypothalamic paraventricular nucleus reveals sex‐ and subregion‐specific differences in two genetic mouse models of autism

open access: yesJournal of Neuroendocrinology, EarlyView.
Abstract Oxytocin (OXT), a neuropeptide hormone essential to a wide range of social functions, has drawn increasing attention as a crucial contributor to the neurobiology of autism spectrum disorder (ASD). Central OXT system disruptions have been reported in several genetic mouse models of ASD; however, a detailed and systematic characterization of ...

Episodic plate tectonics on Venus [PDF]

open access: yes
Studies of impact craters on Venus from the Magellan images have placed important constraints on surface volcanism. Some 840 impact craters have been identified with diameters ranging from 2 to 280 km. Correlations of this impact flux with craters on the
