Understanding the heterogeneity of Alzheimer's disease (AD) is crucial for advancing precision medicine specifically tailored to this disorder. Recent research has deepened our understanding of AD heterogeneity, yet translating these insights from bench to bedside via neuroimaging heterogeneity frameworks presents significant challenges. In this review, we systematically revisit prior studies and summarize the existing methodology of data-driven neuroimaging studies for AD heterogeneity.

KCNJ15 inhibits chemical-induced lung carcinogenesis and progression through GNB1 mediated Hippo pathway.

Polycyclic aromatic hydrocarbons (PAHs) are important environmental carcinogens that can cause lung cancer. However, the underlying epigenetic mechanism during PAHs-induced lung carcinogenesis has remained largely unknown. Previously, we screened some novel epigenetic regulatory genes during 3-methylcholanthrene (3-MCA)-induced lung carcinogenesis, including the potassium inwardly rectifying channel subfamily J member 15 (KCNJ15) gene.

A study on the treatment of rheumatoid arthritis with lipid nanoparticles containing mRNA encoding heat shock protein 10.

In order to delay the progression of Rheumatoid Arthritis (RA) in patients, and to prevent further teratogenesis and irreversible bone erosion through drug intervention in the early stages of inflammation, this experiment used the mRNA encoding heat shock protein 10 (HSP10) (H-mRNA) as the main therapeutic drug and used Microfluidics technology to prepare lipid nanoparticles (LNP) (H-mRNA LNPs) containing H-mRNA, and the surface of H-mRNA-LNPs was modified using heparin particals to obtain the final formulation H-mRNA-LNPs @ heparin/ Protamine. Through the sequence modification and effect evaluation of H-mRNA, we explored the formulation screening, physical characterization, cytotoxicity in vitro, distribution in vivo, pharmacodynamics in vivo, and safety in vivo of the prepared lipid nanoparticles, which proved that this nano-preparation had good anti Rheumatoid Arthritis effects, and conducted a preliminary exploration for the application of nucleic acid drugs in the treatment of diseases outside of tumors. This research would provide new ideas for the treatment of RA.

The number and rate of deaths, as well as disability-adjusted life-years linked to bloodstream infections, were systematically analyzed.

Microcystin-LR induces neuronal damage through mitophagy defects resulted from the downregulated transcription of Scd2 by directly targeting IGF-1R.

Microcystin-LR (MC-LR), a prevalent cyanotoxin present in hazardous cyanobacterial blooms, is recognized as a neurotoxic environmental pollutant that induces brain damage and neurobehavioral deficits. However, the mechanisms underlying MC-LR-induced neurotoxicity remain unclear. This study aims to elucidate the role of mitophagy in MC-LR-induced neurotoxicity both in vitro and in vivo.

Besides traditional organophosphate esters: The ecological risks of emerging organophosphate esters in the Yangtze River basin cannot be ignored.

In addition to traditional organophosphate esters (tOPEs), emerging organophosphate esters (eOPEs) have increasingly been detected in the environment, but their risks remain unclear. This study detected 12 tOPEs and 7 eOPEs in surface water, sediment, and suspended particulate matter (SPM) samples from important aquatic habitats and drinking water sources in Yibin (YB), Yichang (YC), Shanghai (SH), and Poyang Lake (PY) within the Yangtze River basin. The total concentration of OPEs (ΣOPEs) in surface water, sediment, and SPM from these four regions were 22.

Wheat tends to accumulate higher levels of cadmium in the grains than rice under a wide range of soil pH and Cd concentrations: A field study on rice-wheat rotation farmland.

Dietary intake is a predominant pathway of human exposure to environmental Cadmium (Cd), but wheat (Triticum aestivum L.) has not received enough concerns for its risk of Cd contamination. A field survey of Cd-contaminated rice-wheat rotation farmlands in China provided detailed comparison of Cd accumulation capacity by rice and wheat grains.

In vivo adenine base editing ameliorates Rho-associated autosomal dominant retinitis pigmentosa.

Mutations in the Rhodopsin (RHO) gene are the main cause of autosomal dominant retinitis pigmentosa (adRP), 84% of which are pathogenic gain-of-function point mutations. Treatment strategies for adRP typically involve silencing or ablating the pathogenic allele, while normal RHO protein replacement has no meaningful therapeutic benefit. Here, we present an adenine base editor (ABE)-mediated therapeutic approach for adRP caused by RHO point mutations in vivo.

AYVM to AYMM transition on HER2 exon 20 insertion induces TKI resistance in NSCLC.

Pyrotinib, a novel pan-HER tyrosine kinase inhibitor, has demonstrated substantial anti-tumor activity in non-small cell lung cancer (NSCLC) patients harboring HER2 mutations. However, the inevitable resistance to pyrotinib necessitates an in-depth understanding of the underlying mechanisms. In this study, potential resistance-associated mutations were identified through genomic sequencing of clinically paired samples and were validated using in vitro and in vivo models.

Mutation in FvPAL2 leads to light red strawberry fruits and yellow-green petioles.

In recent years, light red or white strawberries have attracted much attention because of their unusual color, however, the mechanism of strawberry color formation, especially light red strawberry color, is not well understood. By EMS mutagenesis of woodland strawberry (Fragaria vesca), we identified two mutants, rg40 and rg120, with light red fruit and yellow-green petiole, and allelic hybridization and BSA mixed-pool sequencing revealed that the phenotype was caused by mutation in the FvPAL2 protein in the anthocyanin synthesis pathway. Enzyme activity experiments showed that the mutant FvPAL2 protein barely catalyzed the substrate conversion normally, thus blocking anthocyanin synthesis, which in turn led to a decrease in anthocyanin accumulation in fruits and petioles.

Lignin and copper nanocomposite coating for antibacterial mask.

Lignin is a natural phenolic polymer characterized with renewable, sustainable and biocompatible, but yet remain underutilized. In the post-pandemic era, people are conventionally reusing mask but without any disinfections to prevent infection of virus in public places, which could lead to accumulation of bacteria and secondary infections. The development of antibacterial mask from lignin would simultaneously address the hygiene issues of used mask due to microbe accumulation and provide novel approach for lignin valorization.

Chitosan-based dihydromyricetin composite hydrogel demonstrating sustained release and exceptional antibacterial activity.

Plant-derived antibacterial agents are increasingly pivotal in mitigating the escalating threat posed by pathogenic microorganisms. Dihydromyricetin (DMY), a plant bioactive compound prevalent in Ampelopsis grossedentata, exhibits remarkable antibacterial properties. However, its poor solubility in water significantly hinders its application in antibacterial therapies, necessitating the exploration of suitable carriers for the loading and sustained release of DMY.

SND1-SMARCA5 interaction strengthened by PIM promotes the proliferation, metastasis, and chemoresistance of esophageal squamous cell carcinoma.

Chromatin remodeling plays a pivotal role in the progression of esophageal squamous cell carcinoma (ESCC), but the precise mechanisms remain poorly understood. Here, we elucidated the critical function of staphylococcal nuclease and tudor domain-containing 1 (SND1) in modulating chromatin dynamics, thereby driving ESCC progression in both in vitro and in vivo models. Our data revealed that SND1 was markedly overexpressed in ESCC cell lines.

Injectable dual-network hyaluronic acid nanocomposite hydrogel for prevention of postoperative breast cancer recurrence and wound healing.

High locoregional recurrence rates and potential wound infections remain a significant challenge for postoperative breast cancer patients. Herein, we developed a dual-network hyaluronic acid (HA) nanocomposite hydrogel composed of herring sperm DNA (hsDNA) bridged methacrylated HA (HAMA) and FeMg-LDH-ppsa nanohybrid chelated catechol-modified HA (HADA) for the prevention of breast cancer recurrent, anti-infection, and promoting wound healing. Dynamic reversible hsDNA cross-linking combined with metal-catechol chelating renders the hydrogel injectability, rapid self-healing ability, and enhanced mechanical properties.

Luteolin inhibits BHV-1 replication and alleviates virus-induced inflammatory responses by regulating PI3K/AKT pathway.

Bovine herpesvirus type 1 (BHV-1) seriously affects the production safety of the cattle industry and leads to epidemics worldwide. Luteolin (Lut), a flavonoid substance, can be found in vegetables, fruits, and herbs and possesses various biological properties. Here, we found that Lut can dose-dependently and significantly inhibit the cytopathic effects of BHV-1, decrease the viral titer, and suppress the BHV-1 gB gene and VP8 protein levels on bovine nasal turbinate osteoblasts (BT) and bovine kidney epithelial cells (MDBK).
