Evidence that mitochondria in macrophages are destroyed by microautophagy.

Microautophagy is an intracellular degradation process in which degradatory organelles, such as the lysosome, directly take up substrates by invagination and/or protrusion of their membranes. Here, we provide evidence that Rab32-positive, lysosome-related organelles in macrophages incorporate various other organelles, including endosomes and mitochondria. Our data indicates that, upon exposure to a mitochondria-damaging reagent, mitochondria can be directly engulfed by the lysosome-like organelles independently of macroautophagy or ESCRT machinery.

Misclassification of recovery in dilated cardiomyopathy by echocardiography as compared to cardiac MRI.

Accurate assessment of cardiac function is the cornerstone of DCM diagnosis and management. Studies have compared CMR and 2D-TTE but the impact of these measurements on HF classification and assessment of EF improvement has not been explored. We aim to compare left ventricular (LV) ejection fraction (EF) and volumes as measured by cardiovascular magnetic resonance (CMR) and two dimensional (2D) transthoracic echocardiography (TTE) in dilated cardiomyopathy (DCM) patients in the initial EF based classification of heart failure (HF) and subsequent follow-up.

Large-scale protein interactome reveals lineage-specific genes driving plant-parasitic nematode adaptive innovations.

Mounting evidence suggests that lineage-specific genes drive phenotype diversity. Plant-parasitic nematodes (PPNs), among the most destructive plant pathogens, have evolved innovated traits required for plant parasitism, yet the genetic basis remains unclear. Here, we identify PPN lineage-specific genes (PPNLSGs) and analyze the large-scale protein interactome of their encoded proteins (PPNLSPs).

Case Report: Genetic predisposition to low-dose NSAID-induced liver injury in real-world China.

Non-steroidal anti-inflammatory drug (NSAID)-induced liver injury represents approximately 10% of reported drug-induced liver injury (DILI) cases, predominantly through idiosyncratic mechanisms. While epidemiological data are largely derived from Western populations with high NSAID utilization, China exhibits lower use of NSAIDs due to cultural preferences and the widespread use of traditional therapies. During the 2022-2023 Omicron outbreak in China, we observed a surge in DILI cases coinciding with increased NSAID use.

Regulation of mA RNA reader protein OsECT3 activity by lysine acetylation in the cold stress response in rice.

N-Methyladenosine (mA) reader proteins, which recognize mA to regulate RNA metabolism, are important for plant adaptation to the changing environment. It remains unknown how the activities of plant mA reader proteins are regulated in plant responses to stress. Here we show that the rice mA reader protein EVOLUTIONARILY CONSERVED C-TERMINAL REGION 3 (OsECT3), required for rice tolerance to cold, is post-translationally modified by lysine acetylation, which reduces its mA-binding activity.

We aimed to assess the impact of increased body mass index (BMI) on myocardial tissue characteristics in patients with HCM.

The potential roles of gut microbiome in porto-sinusoidal vascular disease: an under-researched crossroad.

Accumulating evidence indicates that patients with liver diseases exhibit distinct microbiological profiles, which can be attributed to the bidirectional relationship of the gut-liver axis. Porto-sinusoidal vascular disease (PSVD) has recently been introduced to describe a group of vascular diseases of the liver, involving the portal venules and sinusoids. Although the pathophysiology of PSVD is not yet fully understood, several predisposing conditions, including immunodeficiency, inflammatory bowel disease, abdominal bacterial infections are associated with the increasing in intestinal permeability and microbial translocation, supporting the role of altered gut microbiota and gut-derived endotoxins in PSVD etiopathogenesis.

High-entropy doping in NASICON cathodes: Activating the V/V redox couple and inducing a reversible single solid-solution phase reaction for advanced sodium ion batteries.

NaV(PO) (NVP) with typical NASICON structure is highly regarded as one of the most appealing cathodes for sodium-ion batteries (SIBs) for their excellent structural stability; however, the poor electronic conductivity and irreversible phase transition at high voltage (∼4 V) for the material result in poor rate capabilities and significant capacity degradation during electrochemical reactions. Herein, the high-entropy doping strategy of introducing six types of metal ions into the V-sites in NaV(PO) is used to design a high-performance cathode of NaV(Mn, Ca, Mg, Al, Zr)Nb(PO) (HE-NVP) for SIBs. After the high-entropy doping, a reversible V/V redox pair is activated at high voltage of ∼4 V, which significantly contributes to the enhancement of energy density and operating voltage.

Dramatic Enhancement Enabled by Introducing TiN into Bread-like Porous Si-Carbon Anodes for High-Performance and Safe Lithium Storage.

Doping modifications and surface coatings are effective methods to slow volume dilatation and boost the conductivity in silicon (Si) anodes for lithium-ion batteries (LIBs). Herein, using low-cost ferrosilicon from industrial production as the energy storage material, a bread-like nitrogen-doped carbon shell-coated porous Si embedded with the titanium nitride (TiN) nanoparticle composite (PSi/TiN@NC) was synthesized by simple ball milling, etching, and self-assembly growth processes. Remarkably, the porous Si structure formed by etching the FeSi phase in ferrosilicon alloys can provide buffer space for significant volume expansion during lithiation.

Fragment Correlation Mass Spectrometry Enables Direct Characterization of Disulfide Bond Cleavage Pathways of Therapeutic Peptides.

Therapeutic peptides that are connected by disulfide bonds are often difficult to analyze by traditional tandem mass spectrometry without chemical modification. Using fragment correlation mass spectrometry, we analyzed 56 pairs of fragment ions generated from an equimolar (10 μM) mixture of three cyclic peptides, achieving sequence coverage of 86%, 100%, and 75% for octreotide, desmopressin, and the structural analogue of desmopressin, respectively. In all detected fragment ion pairs, only 20% of the fragment ions are terminal ions, with most of the measured ions only detected by fragment correlation mass spectrometry.
