Detoxifying reactive oxygen species (ROS) that accumulate under saline conditions is crucial for plant salt tolerance. The Salt Overly Sensitive (SOS) pathway functions upstream, while flavonoids act downstream, in ROS scavenging under salt stress. However, the potential crosstalk between the SOS pathway and flavonoids in regulating salt stress responses and the associated mechanisms remain largely unexplored.

Phosphorus is considered an ideal anode material for lithium ion storage by virtue of its high theoretical capacity and moderate lithiation potential. However, issues such as large volume expansion of phosphorus leading to an electrical loss of contact and instability of the solid electrolyte interface hinder its practical performance. Improvement strategies that can effectively suppress volume expansion and provide stable electrical contacts are urgently needed.

This study aimed to assess the efficacy and safety of combining cemiplimab, an anti-PD1 antibody, with isatuximab, an anti-CD38 antibody, in relapsed or refractory extranodal NK/T-cell lymphoma (R/R ENKTL). The hypothesis was that CD38 blockade could enhance the antitumor activity of PD1 inhibitors. Eligible patients received cemiplimab (250 mg on days 1 and 15) and isatuximab (10 mg/kg on days 2 and 16) intravenously every four weeks for six cycles.

Development of a Zeolitic Imidazolate Framework Based Superhydrophobic Surface with Abrasion Resistance, Corrosion Protection, and Anti-icing.

Langmuir

March 2025

Jiangxi Province Key Laboratory of Light Alloy, School of Advanced Manufacturing, Nanchang University, Nanchang 330031, P.R. China.

Herein, a superhydrophobic surface was designed and fabricated based on the "lotus effect" construction mechanism. The zeolitic imidazolate framework (ZIF-90) micro-nanoparticles were initially synthesized via a one-pot method, combined with long-chain stearic acid (STA), and subsequently embedded in polyvinyl butyral (PVB) to form a superhydrophobic surface at room temperature. The superhydrophobic surface demonstrated mechanical stability and retained its superhydrophobicity with a water contact angle (CA) greater than 150°, even at a wear distance of 400 cm.

Adhesion-Assisted Antioxidant-Engineered Mesenchymal Stromal Cells for Enhanced Cardiac Repair in Myocardial Infarction.

ACS Nano

March 2025

School of Biomedical Sciences and Engineering, South China University of Technology, Guangzhou International Campus, Guangzhou 511442, P. R. China.

Mesenchymal stromal cell (MSC) therapy holds great promise for treating myocardial infarction (MI). However, the inflammatory and reactive oxygen species (ROS)-rich environment in infarcted myocardium challenges MSC survival, limiting its therapeutic impact. In this study, we demonstrate that chemical modification of MSCs with anti-VCAM1 and polydopamine (PD) significantly enhances MSC survival and promotes cardiac repair.

Motivation: Computational models are crucial for addressing critical questions about systems evolution and deciphering system connections. The pivotal feature of making this concept recognisable from the biological and clinical community is the possibility of quickly inspecting the whole system, bearing in mind the different granularity levels of its components. This holistic view of system behaviour expands the evolution study by identifying the heterogeneous behaviours applicable, for example, to the cancer evolution study.

Genetic evidence for the suppressive role of zebrafish vhl targeting mavs in antiviral innate immunity during RNA virus infection.

J Immunol

January 2025

Key Laboratory of Breeding Biotechnology and Sustainable Aquaculture, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan, P. R. China.

The von Hippel-Lindau (VHL) tumor suppressor gene VHL is a classic tumor suppressor that has been identified in family members with clear cell renal cell carcinomas, central nervous system and retinal hemangioblastomas, phaeochromocytomas, and pancreatic neuroendocrine tumors. The well-defined function of VHL is to mediate proteasomal degradation of hydroxylated hypoxia-inducible factor α proteins, resulting in the downregulation of hypoxia-responsive gene expression. Previously, we reported that VHL inhibits antiviral signaling by targeting mitochondrial antiviral signaling protein (MAVS) for proteasomal degradation.

Atrial fibrillation (AF) is one of the most common cardiac diseases and a complicating comorbidity for multiple associated diseases. Many clinical decisions regarding AF are currently based on the binary recognition of AF being present or absent with the categorical appraisal of AF as continued or intermittent. Assessment of AF in clinical trials is largely limited to the time to (first) detection of an AF episode.

The neurotoxins of the saxitoxin family can be the origin of the human neurological syndrome of paralytic shellfish poisoning via contaminated marine bivalve vectors. A pre-chromatographic oxidation method is the official testing method in the EU, also known as the 'Lawrence method'. It involves several steps, including toxin extraction, solid-phase clean-up, and oxidation to produce fluorescent derivatives.

Interstitial lung disease (ILD) consists of a group of immune-mediated disorders that can cause inflammation and progressive fibrosis of the lungs, representing an area of unmet medical need given the lack of disease-modifying therapies and toxicities associated with current treatment options. Tissue-specific splice variants (SVs) of human aminoacyl-tRNA synthetases (aaRSs) are catalytic nulls thought to confer regulatory functions. One example from human histidyl-tRNA synthetase (HARS), termed HARS because the splicing event resulted in a protein encompassing the WHEP-TRS domain of HARS (a structurally conserved domain found in multiple aaRSs), is enriched in human lung and up-regulated by inflammatory cytokines in lung and immune cells.

Currently, most cell or tissue transplantations using induced pluripotent stem cells (iPSCs) are anticipated to involve allogeneic iPSCs. However, the immunological properties of iPSCs in an allogeneic setting are not well understood. We previously established a mouse transplantation model of MHC-compatible/minor antigen-mismatched combinations, assuming a hypoimmunogenic iPSC-setting.
