Aims: Transcatheter edge-to-edge repair of the mitral valve (M-TEER) is known for its low complication rates. However, the optimal level and duration of post-procedural care remain unclear. This study aimed to identify the specific timeframe of post-procedural complications following M-TEER.

The damage associated with reperfusion, particularly mitochondrial dysfunction and reactive oxygen species (ROS) formation, has emerged as a crucial factor in the pathogenesis of cardiac diseases, leading to the recognition of mitochondrial proteins as potential markers for myocardial damage. This study aimed to identify differentially expressed proteins based on the type of cardiac injury, in particular those with and without reperfusion.

Emerging evidence suggests that mutant HTT (mHTT) disrupts brain development. To gain mechanistic insights into the neurodevelopmental impact of human mHTT, we engineered male induced pluripotent stem cells to introduce a biallelic or monoallelic mutant 70Q expansion or to remove the poly-Q tract of HTT.

- Gravitational changes from micro- to hypergravity cause various adaptations in the human body, including muscular atrophy, immune impairment, and circulatory system alterations.
- This study observed nine individuals during a parabolic flight, resulting in 11 minutes of microgravity, and analyzed blood samples for changes in plasma proteins before and after the flight.
- Out of 2925 proteins analyzed, 251 showed significant changes, particularly in proteins related to vesicle organization and apoptosis, indicating important physiological alterations due to varying gravity conditions.
Background: Cytomegalovirus (CMV) infections after heart transplantation (HTx) can cause cardiac allograft vasculopathy. Consequently, monitoring and prophylaxis for cytomegalovirus deoxyribonucleic acid (CMV-DNAemia) within the first weeks after HTx is recommended.
Methods: All patients who underwent HTx between September 2010 and 2021 surviving the first 90 days (n = 196) were retrospectively reviewed.
