Despite the outstanding clinical success of immunotherapy, its therapeutic efficacy in glioblastoma (GBM) is still limited. To identify critical regulators of GBM immunity, we constructed a mouse single-guide RNA (sgRNA) library corresponding to all disease-related immune genes, and performed an in vivo CRISPR knockout (KO) screen in syngeneic GBM mouse models. We demonstrated that the deletion of GDF15 in GBM cells ameliorated the immunosuppressive tumor microenvironment (TME) and enhanced the antitumor efficacy of immune checkpoint blockade (ICB) response.

Due to the poor solubility, permeability, stability and tumor-targeting ability of norcantharidin (NCTD), currently commercially available NCTD formulations require patients to take the medicine more frequently. Moreover, the formulation of NCTD themselves have certain toxicity, thus showing unsatisfactory therapeutic outcomes and serious systemic side effects. Based on the specific acidic environment at the tumor site, in this study, the pH-sensitive NCTD solid self-microemulsion (NCTD@CS-DMMA SSME) was prepared by introducing 2,3-dimethylmaleic acid amide modified chitosan (CS-DMMA), and it was wrapped in colon-coated capsule to achieve stable and controlled drug release in the acidic environment of colonic tumors.

This in vivo study explored the impact of TUBB6 inhibition in intracerebral hemorrhage (ICH), focusing on its effects on hematoma volume, microtubule stability, inflammation, neuronal preservation, and sensorimotor recovery. Sprague-Dawley rats was used to induce ICH by collagenase injection into the right striatum, followed by administration of TUBB6 antisense oligonucleotide (ASO) or Control ASO directly into the hematoma site 3 h post-ICH. Outcomes measured included hematoma volume, microtubule stability (acetylated α-tubulin), levels of inflammatory cytokines, mitogen-activated protein kinase (MAPK) pathway activity, neuronal degeneration (Fluoro-Jade C staining), and cell integrity (Cresyl Violet staining).

Zero-shot speaker adaptation seeks to enable the cloning of voices for previously unseen speakers by leveraging only a few seconds of their speech samples. Nevertheless, existing zero-shot multi-speaker text-to-speech (TTS) systems continue to exhibit significant disparities in the synthesized speech quality and speaker similarity when comparing unseen to seen speakers. To address these challenges and improve synthesized speech quality and speaker similarity for unseen speakers, this study introduces an efficient zero-shot speaker-adaptive TTS model, DiffGAN-ZSTTS.

Imbalanced redox homeostasis, involving either oxidative stress or reductive stress, can profoundly impact cellular functions, contributing to various diseases. While the implications of oxidative stress in the adverse effects of nanoparticles have been extensively studied, our comprehension of reductive stress within the context of nano-redox system interactions remains limited. Here we illuminate a domino effect initiated by the dehydrogenase-like activity of transition metal borides.

To evaluate the immunogencity and safety for three immunization schedules of inactivated poliovirus vaccine (IPV) and bivalent oral poliovirus vaccine (bOPV) for providing a basis for further optimization of the polio sequential immunization schedule. To obtain immunogenicity data and to active surveillance the occurrence of adverse events following immunization (AEFI), healthy infants ≥ 2 months of age were randomly chosen in Hebei Province, and were divided into three groups to be vaccinated with IPV-bOPV-bOPV(Group a), IPV-IPV-bOPV(Group b) and IPV-IPV-IPV(Group c) at 2, 3 and 4 months of age respectively. AEFI cases related to poliomyelitis vaccines in Hebei province by passive surveillance from January 1, 2018 to December 31, 2022 were obtained from national adverse event following immunization surveillance system (NAEFISS).

The rapid development of Blockchain Internet of Things (IoT) has intensified the need for efficient and secure cross-chain transmission across heterogeneous systems. However, traditional cross-chain methods, such as hash time-locked contracts and relay chains, focus primarily on security and correctness while neglecting performance optimization. This limitation is particularly pronounced in high-dynamic environments like port areas, where network congestion, high latency, and uneven resource utilization are prevalent challenges.

Mortality from colorectal cancer (CRC) is significant, and novel CRC therapies are needed. A pseudokinase MLKL typically executes necroptotic cell death, and MLKL inactivation protects cells from such death. However, we found unexpectedly that MLKL gene knockout enhanced CRC cell death caused by a protein synthesis inhibitor homoharringtonine used for chronic myeloid leukemia treatment.

Asymmetric catalytic aza-Michael-initiated ring closure of methyleneindolinones with N-tosyloxycarbamates has been established. The reaction using a chiral nickel complex catalyst enabled the formation of a series of spiro-aziridine oxindoles in good yields (up to 99 %) with high stereoselectivity (up to 97 % ee, >19 : 1 dr) under mild reaction conditions. Ring-opening of spiro-aziridine oxindole leads to formation of glycinate-bearing oxindoles with retention of configuration.

In this work, dual active-site Ti-incorporated metal-organic frameworks (MIL-125 and NH-MIL-125) were synthesized by a simple solvothermal process and applied to prepare cyclohexanone oxime from cyclohexylamine oxidation. A low-temperature thermal calcination strategy was used for the modulation of surface properties while maintaining the crystal structure and morphology. The results demonstrated that novel bifunctional NH-MIL-125@250 °C obtained from thermal calcination possessed a large surface area with both oxygen vacancies and surface hydroxyl-active sites, promoting the adsorption and activation of cyclohexylamine and oxygen molecules, respectively.

Previous studies have demonstrated that performance under selective attention and divided attention can be enhanced or impaired, depending on whether the stimuli from different modalities are the same or different. However, it remains unclear whether the modulation of selective attention and divided attention on cross-modal congruence involves shared or distinct neural mechanisms. To clarify this, the present study adopted an audiovisual Stroop task (measuring selective attention) and an audiovisual Matching task (measuring divided attention), using the same physical stimuli, along with event-related potential (ERP) and time-frequency measures.

Herein, a novel recyclable composite microsphere PnBC/ZIF-8-CNs was successfully synthesized by incorporating the zeolitic imidazolate framework-8 (ZIF-8) into 3-aminophenylboronic acid modified bacterial nanocellulose microspheres (PnBC-MS). The structural characteristics were characterized with scanning electron microscopy (SEM), transmission electron microscopy (TEM) as well as element energy X-ray spectroscopy (EDS) mapping, X-ray diffraction (XRD), fourier transform infrared spectrometer (FT-IR), thermogravimetric analysis (TGA), XPS (X-ray photoelectron spectroscopy), and brunauer-emmett-teller (BET). The data showed that adsorption of PnBC/ZIF-8-CNs accorded with the pseudo-first-order kinetic model with spontaneous and endothermic process.

The commercial development of lithium-sulfur batteries (LSBs) has been significantly hindered by the "shuttle effect" and the slow redox kinetics of lithium polysulfides (LiPSs). To solve these problems, researchers have designed a variety of catalysts for the conversion of LiPSs. However, the multi-step lithium polysulfide conversion process is difficult to be effectively solved by a single-function catalyst.

CPAMD8, a constituent of the A2M/C3 (α-2-macroglobulin/complement 3) protein family, is strikingly expressed in the human fetal lens and distal neural retina. Mutations in CPAMD8 have been linked to anterior segment dysgenesis and primary congenital glaucoma. We utilized CRISPR/Cas9 technology to establish a homozygous CPAMD8 knockout human embryonic stem cell line for differentiating retinal organoids, with the intent of exploring the role of CPAMD8 in the early development of the human eye.

In the context of accelerating global warming, which profoundly affects ecosystems and human societies, it is crucial to understand the complex mechanisms through which climate, urban form, and vegetation greening influence land surface temperature (LST). This study investigates the distribution of LST across five urban agglomerations within the Yangtze River Economic Belt (YREB) of China, analyzing both seasonal (summer-winter) and diurnal variations. A range of modeling techniques, including linear regression, Random Forest (RF), and Shapley's Additive interpretation (SHAP), are employed to reveal the complex relationships between LST and its driving factors.
