Value of Label-Free Ubiquitin-Proteomic Analysis on Defining the Protective Mechanism of Valsartan against Doxorubicin-Induced Heart Failure.

Introduction: The cardiotoxicity and subsequent Heart Failure (HF) induced by Doxorubicin (DOX) limit the clinical application of DOX. Valsartan (Val) is an angiotensin II receptor blocker that could attenuate the HF induced by DOX. However, the underlying mechanism of Val in this process is not fully understood.

Oral administration of Folium Artemisiae Argyi-derived exosome-like nanovesicles can improve ulcerative colitis by regulating intestinal microorganisms.

Background: Ulcerative colitis (UC), an inflammatory disease characterized by intestinal barrier dysfunction, poses significant challenges because of the toxicity and adverse effects commonly associated with conventional therapies. Safer and more efficacious treatment strategies are needed.

Purpose: The purpose of this study was to treat UC with Folium Artemisiae Argyi exosome-like nanovesicles (FAELNs) and to explore its related mechanism to provide a safer and more effective means for the treatment of ulcerative colitis.

Macrophage-specific in vivo RNA editing promotes phagocytosis and antitumor immunity in mice.

Macrophages play a central role in antitumor immunity, making them an attractive target for gene therapy strategies. However, macrophages are difficult to transfect because of nucleic acid sensors that can trigger the degradation of foreign plasmid DNA. Here, we developed a macrophage-specific editing (MAGE) system by which compact plasmid DNA encoding a CasRx editor can be delivered to macrophages by a poly(β-amino ester) (PBAE) carrier to bypass the DNA sensor and enable RNA editing in vitro and in vivo.

Tailoring selenization dynamics: How heating rate manipulates nucleation and growth boosts efficiency in kesterite solar cells.

Kesterite Cu2ZnSn(S,Se)4 (CZTSSe) has emerged as a promising photovoltaic material due to its low cost and high stability. The CZTSSe film for high-performance solar cells can be obtained by annealing the deposited CZTS precursor films with selenium (a process known as selenization). The design of the selenization process significantly affects the quality of the absorber layer.

Non-culprit plaque healing on serial OCT imaging and future outcome in patients with acute coronary syndromes.

Background And Aims: Histologic studies indicated that healed plaque, characterized by a multilayered pattern, is indicative of prior atherothrombosis and subsequent healing. However, longitudinal in vivo data on healed plaque formation in non-culprit plaques are limited. This study aimed to investigate serial changes and clinical significance of new layered pattern formation in non-culprit plaques in patients with acute coronary syndromes (ACS) using serial optical coherence tomography (OCT) imaging.
