Persistent cortical excitatory neuron dysregulation in adult haploinsufficient mice.

mutations cause autism spectrum disorder, cognitive deficits, and macrocephaly. mouse models exhibit macrocephaly and transcriptional pathology, with inconsistent findings regarding neurogenesis, neuron function, and behavior. Via stereology and single nucleus transcriptomics (snRNA-seq), we found increased cortical volume was not explained by increase in neuron number.

Recent advances in dissolving microneedle delivery systems for breast cancer therapy.

Introduction: Breast cancer, a malignancy characterized by high recurrence and mortality rates, faces critical bottlenecks in conventional therapies including systemic toxicity and insufficient drug concentration at lesion sites. Dissolving microneedles (DMNs) are micron-scale arrays fabricated from biodegradable materials. By leveraging their unique capability to penetrate the epidermal barrier and deliver drugs with precision, DMNs pioneer a novel therapeutic approach for breast cancer treatment.

Design and Activity Evaluation of Berberine-Loaded Dual pH and Enzyme-Sensitive Colon-Targeting Microparticles.

Ulcerative colitis (UC) is a multifactorial disorder, and conventional oral berberine (BBR) suffers from poor colonic targeting. This study aimed to develop a colon-targeted microparticle system (BBR-ES MPs) based on chitosan (CS) and Eudragit S-100 to enhance BBR delivery efficiency and therapeutic efficacy in UC. : BBR-CS nanocarriers were prepared via ionotropic gelation and coated with Eudragit S-100 to form pH/enzyme dual-responsive MPs.

A real-world study on the efficacy and safety of low-dose PD-1 monoclonal antibody alone or in combination as the first-line treatment for advanced non-small cell lung cancer.

Background: In clinical practice, patients with non-small cell lung cancer (NSCLC) often receive low-dose programmed death-1 (PD-1) monoclonal antibodies due to physical or financial limitations. However, the efficacy and safety of low-dose compared with standard-dose PD-1 monoclonal antibodies remain underexplored.

Methods: This retrospective study included 400 patients with locally advanced or advanced NSCLC treated with PD-1 inhibitors as initial systemic therapy, either as monotherapy or combination therapy.

Evolution of TROP2: Biological insights and clinical applications.

Trophoblast cell surface antigen 2 (TROP2) is a transmembrane glycoprotein that is overexpressed in a wide range of cancers and is associated with poor prognosis and aggressive tumor behavior. This review synthesizes current research on the function of TROP2 in cancer progression through bibliometric analysis, with a special emphasis on advances in the study of antibody-drug conjugates (ADCs) targeting TROP2. We examine the efficacy of targeted therapies against TROP2, in particular the use of sacituzumab govitecan (SG), and evaluate their clinical impact on the treatment of various cancers.

Interspecies hydrogen transfer between cyanobacteria and symbiotic bacteria drives nitrogen loss.

The trace concentration of H in most ecosystems after the Earth's oxidation has long caused the neglect of hydrogenotrophic denitrification for nitrogen loss. Here, we find that the interspecies hydrogen transfer between cyanobacteria and symbiotic bacteria within cyanobacterial aggregates is an undiscovered pathway for nitrogen loss. Cyanobacteria in aggregates can actively generate H under the diel cycle as an electron donor for neighboring hydrogenotrophic denitrifiers.

Enhancers, as distal cis-regulatory elements in the genome, have a pivotal influence on orchestrating precise gene expression. Enhancer RNAs (eRNAs), transcribed from active enhancer regions, are increasingly recognized as key regulators of transcription. N6-methyladenosine (m6A), the most plentiful internal modification in eukaryotic mRNAs, has garnered significant research interest in recent years.

Accurately sensing analysis of active adenine DNA glycosylase (MutY) via the high identification/excision capability to specific base-mismatches of dsDNA chains.

Adenine DNA glycosylase (MutY) is a crucial member of DNA glycosylase family, and the abnormal expression of the human MutY homologs is associated with the pathogenesis of various diseases, therefore, convenient and cost-effective assessing the activity of MutY holds significant biological and medical importance. Herein, the precise identification/excision capacity of MutY to mismatched G-A base pair of dsDNA chains and the DNA-template-dependant fluorescence behaviors of copper nano cluster (CuNCs) was exploited for the accurate sensing of active MutY. Hairpin DNA with G-A base mismatch was excised by MutY to produce dsDNA chains with repetitive AAT-TTA base pairs.

Distribution and migration of pollutant elements during municipal solid waste incineration fly ash melting in a pilot-scale furnace.

The melting/vitrification method is a promising approach for the large-scale, rapid, and harmless disposal of municipal solid waste incineration fly ash (MSWIFA). However, this method inevitably involves challenges related to secondary pollution. A 2 t/d pilot-scale melting furnace was built to investigate the distribution and migration of pollutant components-specifically heavy metals, sulfur, and chloride-within secondary fly ash (SFA), vitrified slag (VS), and ash in the flue gas channel (AFC) during the melting process of MSWIFA.

However, its role and the underlying molecular mechanisms in ICC remain not fully understood.

Sulforaphane inhibits multiple myeloma cell-induced osteoclast differentiation and macrophage proliferation by elevating ferroportin1.

Purpose: Osteolysis is a common complication in patients with multiple myeloma (MM). Our previous studies have demonstrated that MM cells can promote osteoclast differentiation of macrophages. In this study, we explored the effect of sulforaphane (SFN), a natural NRF2 activator found in broccoli, on MM cell-induced osteoclast differentiation.

Adaptive pixel attention network for hyperspectral image classification.

Patch features obtained by fixed convolution kernel have become the main form in hyperspectral image (HSI) classification processing. However, the fixed convolution kernel limits the weight learning of channels, which results in the potential connections between pixels not being captured in patches, and seriously affects the classification performance. To tackle the above issues, we propose a novel Adaptive Pixel Attention Network, which can improve HSI classification by further mining the connections between pixels in patch features.

Residual channel attention based sample adaptation few-shot learning for hyperspectral image classification.

Few-shot learning (FSL) uses prior knowledge and supervised experience to effectively classify hyperspectral images (HSIs), thereby reducing the cost of large numbers of labeled samples. However, existing few-shot methods ignore the correlation between cross-domain feature channels, and the feature representation ability is insufficient. To address above issue, this paper proposes a novel Residual Channel Attention Based Sample Adaptation Few-Shot Learning for Hyperspectral Image Classification(RCASA-FSL) for hyperspectral image classification (HSIC), which can capture and enhance cross-domain dependencies through multi-layer residual connection and random-based feature recalibration.

However, its efficacy in treating multiple myeloma (MM) is yet to be determined. We explored the effects of DADS on MM cells and investigated the synergistic effects of DADS when combined with five anti-MM drugs, including melphalan, bortezomib, carfilzomib, doxorubicin, and lenalidomide.

Co-Delivery of siNRF2 and Sorafenib by a "Click" Dual Functioned Hyperbranched Nanocarrier for Synergistically Inducing Ferroptosis in Hepatocellular Carcinoma.

In the course of antitumor therapy, the complex tumor microenvironment and drug-mediated changes in cell signaling and biological processes lead to drug resistance. The effect of sorafenib is greatly limited by the specific tumor microenvironment induced by antiangiogenic therapy and ferroptosis resistance induced by the upregulation of nuclear factor erythroid-2 related factor 2 (NRF2). In this study, a pH responsive and amphiphilic hyperbranched polyglycerol, HDP, is synthesized based on a co-graft click chemistry pathway.
