Cell-Active, Arginine-Targeting Irreversible Covalent Inhibitors for Non-Kinases and Kinases.

Targeted covalent inhibitors (TCIs) play an essential role in the fields of kinase research and drug discovery. Most existing TCIs are however cysteine- or lysine-reactive, thus severely limiting their potential applications. New types of TCIs capable of covalently targeting other nucleophilic amino acids that are readily available in proteins are urgently needed.

Retrieval of an Aveir Leadless Pacemaker With a Standard Retrieval Catheter by Releasing the Wedged Docking Button Using a Loop Wire Technique.

Introduction: The docking button of the Aveir leadless pacemaker (LP) is occasionally difficult to access due to its inappropriate position in the right ventricle (RV).

Methods And Results: We report a case where the Aveir LP was successfully retrieved by releasing the wedged docking button in the inferior wall of the RV using a loop wire technique.

Conclusion: The loop wire technique may be useful to change the position of the Aveir LP.

In Situ Growth of Metal-Organic Layer on Polyoxometalate-etching Cu2O to Boost CO2 Reduction with High Stability.

Low-cost Cu2O with a suitable band gap holds great potential for solar utilization. However severe photocorrosion and weak CO2 capture capability have significantly hindered their application in artificial photosynthesis. Herein, polyoxometalate (POM)-etching and in situ growth of metal-organic framework (MOF) can simultaneously incorporate electron-sponge and HKUST protective layer into Cu2O.

Application of aqueous two-phase extraction for separation and purification of various adeno-associated viruses.

Objective: Adeno-associated viruses (AAVs) are widely used as gene therapy vectors due to their safety, stability, and long-term expression characteristics. The objective of this work is to develop an aqueous two-phase system (ATPS) as a universal platform for the separation and purification of AAVs.

Results: This study utilized polyethylene glycol (PEG)/salt ATPSs to separate and purify various AAV serotypes, including AAV5, AAV8, and AAV9, which focusing on serotype-specific performance and partial empty capsid removal.

A microenvironment-adaptive GelMA-ODex@RRHD hydrogel for responsive release of HS in promoted chronic diabetic wound repair.

Chronic diabetic wounds present significant treatment challenges due to their complex microenvironment, often leading to suboptimal healing outcomes. Hydrogen sulfide (HS), a crucial gaseous signaling molecule, has shown great potential in modulating inflammation, oxidative stress and extracellular matrix remodeling, which are essential for effective wound healing. However, conventional HS delivery systems lack the adaptability required to meet the dynamic demands of different healing stages, thereby limiting their therapeutic efficacy.
