Promoting Autophagy Mitigates Stress‐Induced Remodeling in Patient iPSC‐CMs with the Phospholamban R9C Mutation

Advanced Science, EarlyView.
The Phospholamban (PLN) R9C mutation reduces SERCA2a binding, increasing calcium recycling and baseline contractility. However, the excess of free PLN promotes pentamer formation, limiting phosphorylation and blunting β‐adrenergic signaling. Under cardiac stress, enhanced functional demands overwhelm proteostasis in PLN R9C cells, leading to misfolded ...

Programming of cardiac implantable electronic devices for conduction system pacing: an information and practical review

Российский кардиологический журнал
Conduction system pacing is widely used as an alternative to right ventricular pacing and, in some cases, as an alternative to biventricular pacing for cardiac resynchronization therapy. Proper programming of an implantable electronic device is essential

Biodegradable Adhesive Systems for Bio‐Integrated Applications

Advanced Science, EarlyView.
Biodegradable adhesives provide temporary yet reliable adhesion while degrading into safe, non‐toxic by‐products under physiological or environmental conditions. This review summarizes recent developments in physical and chemical adhesion mechanisms—including hydrogen bonding, catechol chemistry, amine‐carboxyl coupling, and emerging diazirine and urea

Left bundle branch block causes relative but not absolute septal underperfusion during exercise [PDF]

, 2017
Aims Left bundle branch block (LBBB) often causes septal perfusion defects in radionuclide myocardial perfusion imaging using exercise (Ex) but rarely using vasodilator stress.

Dipiperazine‐Phenyl Derivatives Based on Convergent Molecular Platforms Can Reverse Multidrug Resistance in Gram‐Negative Bacteria by Inhibiting Efflux and Permeabilizing Cell Membranes

Advanced Science, EarlyView.
By integrating a convergent molecular platform strategy, this study designed a novel dual‐target C5 to combat multidrug‐resistant Gram‐negative bacteria. C5 synergistically enhances antibiotic efficacy by inhibiting efflux pumps and increasing bacterial membrane permeability.

Mechanisms of Supraventricular Tachycardia [PDF]

, 1973
In summary, we have found a close association between the stress of A-V nodal conduction and the occurrence of atrial dispersion or aberration. We could not explain atrial dispersion on the basis of incomplete recovery of atrial activity, slowing of ...

Unraveling the Morphological and Functional Maturation Mechanisms Underlying Human Neural Development Using iPSCs‐Derived Neuronal Model

Advanced Science, EarlyView.
Using human induced pluripotent stem cells (hiPSCs)‐derived neuronal model, Tian and colleagues reveal that voltage‐gated calcium channels Cav1.2 and Cav1.3, and their mediated calcium ion influx, are essential for early morphogenesis of human neuronal development, while ECEL1 underlies human neuronal functional developmental maturation through CALM3 ...
