Inhibition of ASIC1a reduces ferroptosis in rheumatoid arthritis articular chondrocytes via the p53/NRF2/SLC7A11 pathway.

The activation of acid-sensing ion channel 1a (ASIC1a) in response to extracellular acidification leads to an increase in extracellular calcium influx, thereby exacerbating the degeneration of articular chondrocytes in rheumatoid arthritis (RA). It has been suggested that the inhibition of extracellular calcium influx could potentially impede chondrocyte ferroptosis. The cystine transporter, solute carrier family 7 member 11 (SLC7A11), is recognized as a key regulator of ferroptosis.

Biglycan stimulates retinal pathological angiogenesis via up-regulation of CXCL12 expression in pericytes.

Retinal pathological angiogenesis (PA) is a common hallmark in proliferative retinopathies, including age-related macular degeneration (AMD), proliferative diabetic retinopathy (PDR), and retinopathy of prematurity (ROP). The mechanisms underlying PA is complex and incompletely understood. In this study, we investigated the role of extracellular matrix (ECM) protein biglycan (BGN) in PA using an oxygen-induced retinopathy (OIR) mouse model, along with hypoxia (1% O) conditions for incubating pericytes and endothelial cells in vitro.

An Antibacterial Hemostasis Sponge of Gelatin/ε-Poly-L-Lysine Composite.

Massive bleeding and bacterial infection of wounds may be life-threatening or even lead to death. Nowadays, gelatin-based hemostatic sponges have been widely used, but gelatin is not antibacterial and has poor structural stability. In this study, we mixed an antibacterial polypeptide, ε-poly-L-lysine (EPL), into gelatin.

EXPRESS: Fluorouracil enhances the anti-pancreatic cancer effect of anti-PD-L1 antibodies via up-regulating the expression of PD-L1 in cancer cells.

Pancreatic cancer is characterized by occult onset, low early diagnosis rate, rapid progress, and poor prognosis. Due to the low response rate and low PD-L1 expression in pancreatic cancer, the therapeutic application of PL-L1 inhibitors in pancreatic cancer is greatly limited. In vitro studies showed that the expression of PD-L1 increased in pancreatic cancer cells stimulated by fluorouracil (5-FU).

Tree Lifespans in a Warming World: Unravelling the Universal Trade-Off Between Growth and Lifespan in Temperate Forests.

Tree growth and lifespan are key determinants of forest dynamics, and ultimately control carbon stocks. Warming and increasing CO have been observed to increase growth but such increases may not result in large net biomass gains due to trade-offs between growth and lifespan. A deeper understanding of the nature of the trade-off and its potential spatial variation is crucial to improve predictions of the future carbon sink.

Beating the Size-Dependent Limit with Spin-Lattice Coupling in Nanomagnetism.

Further miniaturization of magnetic nanomaterials is intrinsically accompanied by a reduction in spin ordered domains, resulting in size-dependent magnetic behaviors. Consequently, a longstanding roadblock in the advancement of nanodevices based on magnetic nanomaterials is the absence of a method to beat the size-dependent limit in nanomagnetism. Here, we discover and exploit a spin-lattice coupling effect in three-dimensional freestanding magnetic nanoparticles to beat the size-dependent limit for the first time.

Orthorhombic Covalent Organic Frameworks with fmj Topology as Photocatalyst for Hydrogen Evolution.

Three-dimensional covalent organic frameworks (3D COFs), a class of highly porous crystalline polymers, have exhibited great potentials in many applications. However, the reported topologies of 3D COFs have been limited to high-symmetry crystal systems, which significantly hindered the development of such functional materials. Herein, we demonstrate the first construction of four highly crystalline orthorhombic 3D COFs with an unprecedented fmj topology, based on judiciously choosing rotatable monomers.

Photocatalytic acceptorless dehydrogenation of flavanones by cationic Eosin Y as a bifunctional catalyst.

We report the first example of photocatalytic acceptorless dehydrogenation using cationic Eosin Y as a bifunctional photocatalyst, without metal catalysts or HAT reagents. Under Bayesian optimized conditions, a wide range of flavones were synthesized in moderate to excellent yields, many of which were reported with biological activities. Mechanistic studies suggest that flavones likely form through two HAT processes, with hydrogen release occurring photoredox.

The role of miR-155 in cardiovascular diseases: Potential diagnostic and therapeutic targets.

Cardiovascular diseases (CVDs), such as atherosclerotic cardiovascular diseases, heart failure (HF), and acute coronary syndrome, represent a significant threat to global health and impose considerable socioeconomic burdens. The intricate pathogenesis of CVD involves various regulatory mechanisms, among which microRNAs (miRNAs) have emerged as critical posttranscriptional regulators. In particular, miR-155 has demonstrated differential expression patterns across a spectrum of CVD and is implicated in the etiology and progression of arterial disorders.

Causal associations between hypertension and abnormal brain cortical structures: Insights from a bidirectional Mendelian randomization study.

Background: Observational studies suggest that hypertension affects brain cortical structure. However, the potential causal association has yet to be entirely determined. Thus, we aim to assess the causality between hypertension and abnormal cortical structure.

Left ventricular trabecular complexity for risk stratification of cancer therapy-related cardiac dysfunction in breast cancer.

The left ventricular trabecular fractal dimension (LVTFD) derived from cardiac magnetic resonance reflects myocardial trabecular complexity, which is associated with cardiovascular disease risk. Baseline risk stratification of cancer therapy-related cardiac dysfunction (CTRCD) in patients with breast cancer who received anthracycline is a very important clinical issue. In this study, we used the Cox model to derive and validate a new score system based on LVTFD for baseline risk stratification of CTRCD in breast cancer patients receiving anthracycline.

Impaired network organization in mild age-related hearing loss.

Age-related hearing loss (ARHL) is considered one of the most common neurodegenerative disorders in the elderly; however, how it contributes to cognitive decline is poorly understood. With resting-state functional magnetic resonance imaging from 66 individuals with ARHL and 54 healthy controls, group spatial independent component analyses, sliding window analyses, graph-theory methods, multilayer networks, and correlation analyses were used to identify ARHL-induced disturbances in static and dynamic functional network connectivity (sFNC/dFNC), alterations in global network switching and their links to cognitive performances. ARHL was associated with decreased sFNC/dFNC within the default mode network (DMN) and increased sFNC/dFNC between the DMN and central executive, salience (SN), and visual networks.
