Verapamil inhibits ferroptosis in septic acute lung injury by blocking L-type calcium channels.

Acute lung injury (ALI) and its severe form, acute respiratory distress syndrome (ARDS), result from pulmonary edema and alveolar-capillary barrier disruption due to inflammation, often triggered by conditions like sepsis. Sepsis-induced ALI (SALI) involves extensive damage to vascular endothelium and alveolar epithelium, leading to respiratory failure. Our study explores ferroptosis, an iron-dependent cell death pathway, and calcium dysregulation in SALI.

Dimethyl Fumarate Is Repurposed to Ameliorate Aortic Aneurysm and Dissection in Mice.

Aortic aneurysm and dissection pose fatal threats but no effective drug therapies are available. Previous work has been directed to reduce risk factors or target key pathological events, but none of the translational efforts succeeds. Here, we attempt to repurpose dimethyl fumarate (DMF), an FDA-approved immunomodulatory drug for multiple sclerosis, for the treatment of aortic aneurysm and dissection.

This study aims to identify differentially expressed PANoptosis-related genes (DE-PRGs) in DR, offering insights into the disease's pathogenesis and potential diagnostic tools.

Modeling the Global Impact of Chlorine Chemistry on Secondary Organic Aerosols.

Simulation of secondary organic aerosol (SOA) in models has been an uncertain component in determining the impacts of atmospheric aerosols on air quality and climate. Recent studies have shown that reactive chlorine can rapidly oxidize volatile organic compounds (VOCs), trigger SOA formation, and alter other oxidants, thus having a potentially significant effect on SOA, which has not been thoroughly investigated at the global scale. Here, we developed a chlorine-SOA simulation within a global chemical transport model along with updated anthropogenic continental chlorine emissions.

Synergistic Enhancement of Antibacterial and Osteo-Immunomodulatory Activities of Titanium Implants via Dual-Responsive Multifunctional Surfaces.

Bone implant-associated infections and inflammations, primarily caused by bacteria colonization, frequently result in unsuccessful procedures and pose significant health risks to patients. To mitigate these challenges, the development of engineered implants with spatiotemporal regulation capabilities, designed to inhibit bacterial survival and modulate immune responses in the early stage, while promoting bone defect healing in the late stage is proposed. The implants are functionalized with ε-poly-l-lysine-phenylboronic acid (PP) via dynamic boronic ester bonds, which facilitate its release through a reactive oxygen species (ROS) and pH-responsive strategy, thereby establishing an antibacterial microenvironment on and around the implants.

Pepper is a significant cash crop, and is an exemplary variety of pepper cultivated for its distinctive flavor and substantial nutritional value. Polyploidization of plants often leads to an increase in their biomass and improved stress tolerance, and thus has important applications in plant breeding and improvement. In this study, germplasm innovation was carried out by polyploidy induction of by colchicine.

Blue Energy Extraction Performance by Polyelectrolyte-Coated Porous Electrodes: Effects of Opposing Polyelectrolyte Interaction in Micropores.

In the capacitive mixing technique, the electrode used to extract blue energy is typically composed of a carbon-based porous electrode material. Polyelectrolyte (PE) surface coating on porous electrodes serves as an intermediate soft layer, which can significantly enhance the energy extraction performance (EEP). Herein, the blue energy extraction performance by using PE-coated electrodes is studied by a statistical thermodynamic theory, with the exploration of the interplay effects between opposing polyelectrolyte interactions and pore size.

CO2 chemistry of Cu(100) regulated by Ni deposition and pressure.

Modification of copper-based catalysts by incorporating a second metal is prevailing in developing high-performance catalysts for CO2 hydrogenation. In particular, the insight into how the reaction is influenced is key to understanding the nature of the strategy. Herein, we show that both intermediates and reaction pathways of CO2 over Cu(100) are conspicuously regulated by Ni deposition and CO2 pressure.

The time-averaged serum uric acid can better predict the prognosis of IgA nephropathy.

Background And Aim: To understand the clinical and pathological characteristics of patients with IgA nephropathy (IgAN) complicated by hyperuricemia, and to analyze the time-averaged SUA (TA-SUA) on the prognosis of IgAN.

Methods And Results: A retrospective analysis of 718 IgAN patients with diagnosis confirmed by renal biopsy and follow-up of more than 1 year was performed. At least two serum uric acid (SUA) levels were measured at intervals of 0.

Kechuan Decoction mitigates apoptosis of airway epithelial cells by improving lipid metabolism disorders and mitochondria dysfunction in HDM-induced asthma.

Background: The airway epithelium serves as the first line of defense between the lung's internal environment and the external environment, functioning through physical barriers and mucus-ciliary clearance to protect against external allergens and other harmful substances. Airway epithelial damage is a common feature of asthma, and research has shown that apoptosis plays a significant role in airway injury and inflammation in asthma. Although Kechuan Decoction (KCD) has demonstrated clinical efficacy in treating pediatric asthma, its precise mechanism of action remains unclear.

SCGN recruits macrophages by regulating chemokine secretion in clear cell renal cell carcinoma.

Immunotherapy is considered to be one of the most promising curative modalities for cancer, and the effectiveness of immunotherapy depends on the abundance of immune cells in the tumor microenvironment (TME). Immunotherapy tends to be more effective in "hot tumors" characterized by a high abundant immune cells. Our previous studies found that secretagogin (SCGN) showed intranuclear aggregation in the early stages of clear cell renal cell carcinoma (ccRCC) development.

GXYLT2: an emerging therapeutic target and predictive biomarker for anti-PD-1 efficacy in clear cell renal cell carcinoma.

There are studies reporting that glucoside xylosyltransferase 2 (GXYLT2) has a role in promoting tumor progression, but its role in clear cell renal cell carcinoma (ccRCC) remains unclear. In this study, RT-qPCR and western blotting were employed to detect the expression level of GXYLT2. RNA interference assays were used to knock down GXYLT2.

Hyperactivation of Hedgehog signaling impedes myelin development and repair via cholesterol dysregulation in oligodendrocytes.

The failure to remyelinate demyelinated axons poses a significant challenge in the treatment of multiple sclerosis (MS), a chronic inflammatory demyelinating disease of the central nervous system. Here, we investigated the role of Hedgehog (Hh) signaling in myelin formation during development and under pathological conditions. Using conditional gain-of-function analyses, we found that hyperactivation of Hh signaling in oligodendrocyte precursor cells (OPCs) inhibits oligodendrocyte (OL) differentiation and myelination.
