Background: The bone marrow microenvironment, comprising various cell types and molecular signals, finely orchestrates the self-renewal and lineage commitment of hematopoietic stem cells (HSCs). Although most investigations have centered on mesenchymal stem cells (MSCs) from long bones, the distinct properties and immunoregulatory functions of craniofacial bone marrow derived MSCs remain largely unexplored. Notably, jawbone MSCs not only exhibit a robust capacity for promoting hematopoietic regeneration but also offer therapeutic potential in infectious diseases.

Constructing strong interfacial interactions between the carbon coating layer and the MnO anode is highly desirable for enhancing its structural stability and electronic conductivity. Herein, an aminated graphite/MnO composite (MnO@300NG) with a strong Mn-N-C heterointerface has been designed via coupling hydrothermal self-assembly with a calcination strategy. This stable structure can fully expose more Li-ion storage active sites and accelerate the charge transfer rate and Li-ion diffusion kinetics.

RNA-binding proteins (RBPs) are critical regulators of post-transcriptional processes, playing essential roles in nutrient metabolism and metabolic homeostasis. This literature review explores how RBPs influence the metabolism of glucose, lipid, and amino acid metabolism by controlling processes like mRNA stability and translation regulation. The dysregulation of RBPs, including HuR, PTB, and YTHDF1, is linked to metabolic diseases such as obesity, diabetes, and non-alcoholic fatty liver disease.

Cuproptosis, a copper-induced form of regulated cell death, holds therapeutic promise in cancer but remains mechanistically unclear. We developed Mito-TPCA, a mitochondrial thermal proximity coaggregation strategy combining enzyme-catalyzed proteome labeling with thermal profiling, to map mitochondrial protein-protein interaction dynamics during cuproptosis. This approach revealed that copper disrupts the association of pyruvate dehydrogenase kinases (PDKs) with the pyruvate dehydrogenase (PDH) complex by targeting lipoyl domains, triggering PDH dephosphorylation and aberrant activation.

In children, hyper-IgM syndrome type 1 (HIGM1) is a type of severe antibody disorder, the pathogenesis of which remains unclear. The antibody diversity is partially determined by the alternative splicing (AS) in the germline, which is mainly regulated by RNA-binding proteins, including Breast cancer amplified sequence 2 (Bcas2). However, the effect of Bcas2 on AS and antibody production in activated B cells, the main immune cell type in the germline, remains unknown.

Oxidative stress and lipid peroxidation-derived aldehydes, such as acrolein, play a central role in the pathology of spinal cord injury (SCI) and have emerged as promising therapeutic targets. Mitochondrial aldehyde dehydrogenase-2 (ALDH2) is a key oxidoreductase responsible for detoxifying reactive aldehydes. Pharmacological activation of ALDH2 using Alda-1, a selective agonist, has been shown to reduce aldehyde accumulation, alleviate inflammation, and enhance functional recovery in experimental SCI models.

Sarbecoviruses, such as SARS-CoV-2, utilize angiotensin-converting enzyme 2 (ACE2) as the entry receptor; while merbecoviruses, such as MERS-CoV, use dipeptidyl peptidase 4 (DPP4) for viral entry. Recently, several MERS-related coronaviruses, NeoCoV and PDF-2180, were reported to use ACE2, the same receptor as SARS-CoV-2, to enter cells, raising the possibility of potential recombination between SARS-CoV-2 and MERS-related coronaviruses within the co-infected ACE2-expressing cells. However, facing this potential recombination risk, the serum and antibody cross-reactivity against MERS/MERS-related coronaviruses after SARS-CoV-2 vaccination and/or infection is still elusive.

Porous carbon coated manganese compounds nanoparticles (MnX, X = P, O or S) is a kind of potential catalysts for oxygen electrocatalysis due to the controllable d-band center, while the complex mechanism and performance difference is yet to reveal due to the lack of catalyst platform. Herein, the ORR catalytic activity and difference reason between manganese phosphide, oxide, and sulfide are tested and discussed via manganese compounds contained carbon-based catalyst platforms synthesis and Density functional theory (DFT). Manganese compounds nanoparticles active sites are uniformly distributed in porous carbon fibers/graphene composite, which guarantees the high mass transfer ability and conductive ability.

Nickel-based catalysts show great potential as promising candidates for the electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF). However, the limited adsorption capacity of nickel-based catalysts for OH and HMF limits their further development. In this study, amorphous Fe/NiOOH-SO was generated from nanosheets (Fe/NiOOH-NiS), which was pre-fabricated on nickel foam via pre-reconstruction and anionic regulation strategy.

Oxidative stress is widely recognized as a critical factor in the functional deficits after spinal cord injury (SCI). Oxidative stress and lipid peroxidation-derived aldehydes such as acrolein are known to play a key role in SCI pathology and have therefore emerged as valuable therapeutic targets. This study introduces a novel phenelzine analogue (PhzA), designed to retain the acrolein scavenging capability of phenelzine (Phz) while removing its undesirable monoamine oxidase (MAO) inhibition effects through structure-based modification.

Nonsteroidal anti-inflammatory drug (NSAID) enteropathy is a serious clinical complication with no effective treatments available. Modulating the intestinal microbiota through dietary and nutritional targets is a promising strategy for preventing NSAID enteropathy. This study aimed to investigate the protective effect and underlying mechanisms of the probiotic (CB) on indomethacin (IND)-induced enteropathy.

Gastric cancer (GC) is a prevalent malignant tumor that originates from the epithelial cells of the gastric mucosa, predominantly in the form of adenocarcinoma. Extensive research has confirmed the significant role of autophagy in the initiation, progression, and chemoresistance of GC. The potential of traditional Chinese medicine (TCM) to exert anti-tumor effects by modulating autophagy has been demonstrated, particularly in the context of GC prevention and treatment.

Metabolic syndrome (Mets) is an important contributor to morbidity and mortality in cardiovascular, liver, neurological, and reproductive diseases. Short-chain fatty acid (SCFA), an organismal energy donor, has recently been demonstrated in an increasing number of studies to be an important molecule in ameliorating immuno-inflammation, an important causative factor of Mets, and to improve lipid distribution, blood glucose, and body weight levels in animal models of Mets. This study reviews recent research advances on SCFA in Mets from an immune-inflammatory perspective, including complications dominated by chronic inflammation, as well as the fact that these findings also contribute to the understanding of the specific mechanisms by which gut flora metabolites contribute to metabolic processes in humans.

To model craniofacial malformations caused by vitamin A deficiency (VAD), we expressed a dominant-negative retinoid receptor mutation in osteoblasts to specifically inhibit RAR transcriptional activity in mice. This approach allowed us to investigate the effects of VAD on cranial hypomineralization, mandibular deformity, and clavicular hypoplasia in clinical cases. In this study, microcomputed tomography (microCT) scanning of the craniomaxillofacial region of mice represented a valuable tool for studying the growth and development of this animal model.

Developing high-performance and low-cost electrodes for hydrogen and oxygen evolution reactions (HER and OER, respectively) represents a pivotal challenge in the field of water electrolysis. Herein, W doped NiFe LDH nanosheets (NiFe-W/NF) were immobilized on nickel foam (NF) through one-step corrosion engineering, which induced the coexistence of α-Ni(OH) and β-Ni(OH). The doping of large atomic radius W influenced the growth of crystal planes of Ni(OH), promoting the formation of α-Ni(OH), which results in large layer spaces and neatly arranged nanosheets structure.
