Demonstration of beat‐to‐beat, on‐demand ATP synthesis in ventricular myocytes reveals sex‐specific mitochondrial and cytosolic dynamics

The Journal of Physiology, EarlyView.
Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

Plasmalemmal VDAC controversies and maxi-anion channel puzzle [PDF]

, 2012
The maxi-anion channel has been observed in many cell types from the very beginning of the patch-clamp era. The channel is highly conductive for chloride and thus can modulate the resting membrane potential and play a role in fluid secretion/absorption ...

Systematic review of the value-driven attentional capture paradigm in visual attention studies: Evidence from 52 experiments

Acta Psychologica
Human visual attention is strongly influenced by rewards, affecting both top-down and bottom-up attentional processes. The value-driven attentional capture (VDAC) paradigm, introduced by Anderson et al.

Microenvironment‐Responsive Nanomedicine Enables Vertical Modulation of Mitochondrial Pathological Networks in Myocardial Ischemia–Reperfusion Injury

Advanced Science, Volume 13, Issue 55, 5 October 2026.
A mitochondria‐targeted, microenvironment‐responsive nanoplatform enables pH/ROS‐triggered co‐delivery of berberine and isoliensinine to orchestrate ROS scavenging, inflammation suppression, and apoptosis inhibition. This vertical modulation of mitochondrial pathological networks preserves mitochondrial function and effectively mitigates myocardial ...

Ten Years of High Resolution Structural Research on the Voltage Dependent Anion Channel (VDAC)—Recent Developments and Future Directions

Frontiers in Physiology, 2018
Mitochondria are evolutionarily related to Gram-negative bacteria and both comprise two membrane systems with strongly differing protein composition. The major protein in the outer membrane of mitochondria is the voltage-dependent anion channel (VDAC ...

CDK4/MERCs/PINK1 Axis Drives PFOA/HFPO‐TA‐Induced Cardiac Senescence via Mitophagy Defect and cGAS‐STING Activation: In Vitro Amelioration by Cycloastragenol

Advanced Science, Volume 13, Issue 56, 9 October 2026.
The present study demonstrated that PFOA and HFPO‐TA exposure suppressed CDK4, disrupted MERCs and impaired PINK1/Parkin‐mediated mitophagy, thereby accelerating cardiac senescence, whereas CAG effectively reversed these pathological changes in vitro. Our findings identify CDK4 as a critical regulator bridging mitophagy defects and cardiac senescence ...

Spatiotemporal heterogeneity and dynamic evolution of microglial glucose metabolic reprogramming in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract Alzheimer's disease (AD) is accompanied by persistent disturbances in brain energy metabolism, and microglial glucose metabolic reprogramming constitutes an important link among pathological protein deposition, neuroinflammation, and impaired clearance.

Maternal and perinatal effects of vaginal delivery after caesarean section

Medicine Science, 2016
We aimed to determine the risk factors of vaginal delivery after caesarean section (VDAC) that may be effective on maternal and neonatal outcomes and compare the pregnancy outcomes of VDAC with the results of the previous caesarean delivery.

Cell Type‐Specific Extracellular Vesicles in Mouse Brain: Proteomic Signatures Highlight Astrocytic GlialCAM Network and GPCR Enrichment

Glia, Volume 74, Issue 10, October 2026.
Cell type–specific EVs were isolated from mouse brain and profiled by proteomics. Each EV subtype exhibited proteomic signatures consistent with the specialized functions of its cell of origin. Astrocyte‐derived EVs (ADEVs) were enriched for the GlialCAM/MLC1 network and GPCRs.

Insights into VDAC Gating: Room-Temperature X-ray Crystal Structure of mVDAC-1

Biomolecules
The voltage-dependent anion channel (VDAC) is a crucial mitochondrial protein that facilitates ion and metabolite exchange between mitochondria and the cytosol. Initially characterized over three decades ago, the structure of VDAC-1 was resolved in 2008,
