Echocardiographic diagnosis of left ventricular outflow tract obstruction after mitral valve replacement with subvalvular preservation

open access: yes, 2002
We describe two cases of left ventricular outflow tract obstruction after mitral valve replacement with complete retention of the subvalvular apparatus. The first patient deteriorated immediately after insertion of a high-profile bioprosthesis.

Real‐Time Neurochemical Sensing in Zebrafish: Electrochemical and Fluorescent Approaches

open access: yesAnalysis &Sensing, Volume 6, Issue 6, November 2026.
The use of zebrafish has emerged as a powerful approach for real‐time neurochemical measurements. This review highlights recent advances in electrochemical and fluorescent sensing strategies that enable dynamic measurements in live preparations of this complex vertebrate. These complementary approaches provide new insights into neurochemical signaling,

Targeting Ninjurin‐1‐Mediated Microglial Pyroptosis Attenuates Neuroinflammation and Neuronal Injury Following Intracerebral Hemorrhage

open access: yesBrain and Behavior, Volume 16, Issue 11, November 2026.
In response to intracerebral hemorrhage, NF‐κB signaling upregulates Nlrp3 and Ninjurin‐1 (Ninj1) in microglia. NLRP3 inflammasome activation triggers GSDMD pore formation, whereas Ninj1 oligomerizes to execute terminal plasma membrane rupture (PMR) and DAMP release (such as HMGB1).

Comparison Between the Acurate Neo and the Acurate Neo 2 Transcatheter Heart Valve System: Impact of Midframe Under‐Expansion

open access: yesCatheterization and Cardiovascular Interventions, Volume 108, Issue 5, Page 1784-1794, November 1, 2026.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) with the Acurate Neo has been linked to a significant incidence of paravalvular leakage (PVL), addressed by the Acurate Neo 2 incorporating an active sealing skirt. Recent findings suggest that midframe under‐expansion is associated with worse outcomes.

Neutrophils: Heterogeneity, Biology, Diseases, and Therapeutic Strategies

open access: yesMedComm, Volume 7, Issue 11, November 2026.
Neutrophils exhibit remarkable functional plasticity and play dual roles in tissue protection and disease progression. This review summarizes their key biological functions and highlights the shift from conventional broad‐spectrum interventions to neutrophil‐based drug delivery systems.
