Diabetes mellitus exacerbates cardiovascular remodeling in elderly Chinese by affecting aortic diameter and pulsatile load.

Cardiovascular health is negatively impacted by arterial stiffening, which increases pulsatile load and elevates left ventricular workload. Aortic dilatation may compensate for the pulsatile overload resulting from arterial stiffening. Previous studies have shown a negative correlation between diabetes and aortic diameter, suggesting that diabetes may impair aortic dilatation and thereby compromise compensatory buffering capacity.

Binding Properties of Methyltrimethoxysilane-Modified Silica Sol Particle Surfaces and Their Molecular Dynamics Simulations.

The surface bonding of silica sol particles modified by methyltrimethoxysilane (MTMS) at different temperatures was investigated. Following modification, MTMS hydrolysis products react with silica hydroxyl groups on the surface of silica particles to create a -Si-O-Si-network structure. Additionally, the hydrolysis products formed hydrogen bonds with the silica hydroxyl groups in the silica sol, which strengthened the bonding strength between the silica particles in a synergistic manner.

USP47 enhances NRP1-mediated angiogenesis to promote gastric cancer progression.

Gastric cancer (GC) is a leading cause of cancer-related mortality, particularly in East Asia, where its incidence remains high. The limited prognosis for advanced GC patients underscores the need for new therapeutic strategies targeting key molecules involved in tumor progression. In this study, we investigated the role of the deubiquitinating enzyme USP47 in GC progression, focusing on its interaction with Neuropilin-1 (NRP1), a co-receptor known to enhance angiogenesis.

The deubiquitination-PARylation positive feedback loop of the USP10-PARP1 axis promotes DNA damage repair and affects therapeutic efficacy of PARP1 inhibitor.

PARP1 initiates DNA repair pathways including single-strand break repair (SSBR) by recruiting multiple DNA repair factors via poly ADP-ribosylation (PARylation) of target proteins. However, how PARP1 is stabilized and activated to promote DNA damage repair remains unclear. Here we report that DNA damage generates a ROS signal, which triggers USP10 to interact with and stabilize PARP1 by deubiquitinating the K418 site in an ATM-dependent manner.

Multiple regulatory mechanisms, functions and therapeutic potential of chaperone-mediated autophagy.

Autophagy refers to the proteolytic degradation of cytoplasmic components by lysosomes, and includes three defined types: macroautophagy, chaperone-mediated autophagy (CMA), and microautophagy. Although the regulatory pathways of macroautophagy are well defined, how CMA is accurately regulated remains less understood. In recent years, emerging evidence has suggested that chaperone-mediated autophagy is regulated by multiple mechanisms at nucleic acid and protein levels.

[Mycology, chemical components, bioactivities, and fermentation process regulation of Sanghuang: a review].

Sanghuang, a famous ethnomedicine widely used in China, Japan, Korea and other countries for a long history, is produced from the dried fruiting bodies of the medical fungi belonging to Sanghuangporus. With abundant bioactive natural chemicals including polysaccharides, flavonoids, triterpenoids, and polyphenols, Sanghuang exhibits anticancer, antioxidant, blood glucose-and lipid-lowering, liver protecting, anti-inflammatory, antimicrobial, and gout symptom-relieving effects, thus demonstrating broad application and development prospects in the pharmaceutical and food fields. However, the sustainable development of Sanghuang resources is limited by the scarce stock of wild resources, the diverse original fungi of cultivated Sanghuang, the inconsistency of local standards of Sanghuang materials or products, and the lagging application of Sanghuangporus mycelia.

Different temperatures leakage mechanisms of (AlO)(HfO) gate Dielectrics deposited by atomic layer deposition.

(AlO)(HfO) films with varying compositions were deposited on silicon substrates via plasma-enhanced atomic layer deposition (PEALD), and metal-oxide-semiconductor (MOS) capacitors were fabricated. The impact of varying induced Al content on the dielectric properties of HfO was examined through electrical measurements. The results showed that increasing Al content raised the flat-band voltage, reduced the interface state density (D), and significantly lowered the leakage current at a given voltage.

Oxygen-Independent Photodynamic Therapy-Mediated Selective Consumption of M1 Macrophage Against Ventricular Arrhythmias via Sympathetic Neuromodulation.

The occurrence of myocardial infarction (MI)-induced malignant ventricular arrhythmias (VAs) is closely associated with the hyperactivation of left stellate ganglion (LSG). Proinflammatory M1 macrophage is reported to aggravate sympathetic overactivation and cause VAs. Therefore, the depletion of M1 macrophage is anticipated to inhibit LSG overactivation and alleviate MI-induced VAs.

Enabling High-Performance Multi-Resonant TADF Emitters via Intramolecular Hydrogen Bond.

Hydrogen bonds (HBs), prevalent strong interactions in organic compounds, can effectively constrain single bond rotation, leading to rigid planar configurations. This rigidity enhances emission efficiency and narrows the emission spectrum of luminescent materials. Recent advances have leveraged HBs to advance high-performance donor-acceptor thermally activated delayed fluorescence (TADF) materials.

OsPIPK-FAB, A Negative Regulator in Rice Immunity Unveiled by OsMBL1 Inhibition.

Phosphatidylinositol signaling system plays a crucial role in plant physiology and development, phosphatidylinositol phosphate kinases (PIPKs) are one of the essential enzymes responsible for catalyzing the synthesis of phosphatidylinositol bisphosphate (PIP2) within this signaling pathway. However, its mechanism of signal transduction remains poorly exploited in plants. OsMBL1, a jacalin-related mannose-binding lectin in rice, plays a crucial role in plant defense mechanisms, acting as a key component of the pattern-triggered immunity (PTI) pathway.

Lactylation in cancer: Mechanisms in tumour biology and therapeutic potentials.

Lactylation, a recently identified form of protein post-translational modification (PTM), has emerged as a key player in cancer biology. The Warburg effect, a hallmark of tumour metabolism, underscores the significance of lactylation in cancer progression. By regulating gene transcription and protein function, lactylation facilitates metabolic reprogramming, enabling tumours to adapt to nutrient limitations and sustain rapid growth.

New Insight into Quantity-Dependent Self-Assembly Pattern of Light Levitating Droplet Clusters.

It has been reported that the self-assembly pattern of light levitating droplet clusters above the hot gas-liquid interface is dependent on the quantity of droplets. However, the already-reported theoretical explanation of the quantity-dependent self-assembly pattern cannot work well when the quantity of the light levitating droplet exceeds 15. Herein, we propose a new theoretical perspective to understand the self-assembly of a light levitating droplet cluster by referring to the classical densest packing problem of identical rigid circles in a larger circle with the introduction of the minimum total potential energy principle.

Improving the Oxidation Resistance of Phenolic Resin Pyrolytic Carbons by In Situ Catalytic Formation of Carbon Nanofibers via Copper Nitrate.

Phenolic resin pyrolytic carbons were obtained by catalytic pyrolysis of phenolic resin at 500 °C, 600 °C, 700 °C, and 800 °C for 3 h in an argon atmosphere using copper nitrate as a catalyst precursor.
