Xiaochaihutang ameliorates depression-like behaviors induced via chronic social defeat stress by regulating exon-specific Bdnf transcription through H3K18 acetylation in the hippocampus of mice.

Introduction: Depression is a prevalent and persistent mental disease characterized by symptoms such as anhedonia, anxiety, and desperation. Although our previous study shows that Xiaochaihutang (XCHT) upregulates hippocampal brain-derived neurotrophic factor (BDNF) levels in depressed mice and rats, the underlying mechanism requires further clarification.

Objectives: To assess the mechanism by which XCHT regulates hippocampal BDNF expression in chronic social defeat stress (CSDS)-induced mice.

English Trans-Adaptation and Content Validity Testing of the Positive Psychological Capital Questionnaire (PPQ-E) Among Rural Youth.

Background: Psychological capital (PsyCap), the combination of hope, self-efficacy, resilience, and optimism, is gaining relevance for understanding youth life satisfaction and wellbeing. Typically a variety of unidimensional scales are used to measure PsyCap in mental health studies with English-speaking youth, limiting the ability to compare results across studies. The Positive Psychological Capital Questionnaire (PPQ) is a multi-dimensional tool developed with Asian youth to measure general PsyCap.

Targeting GDF15 to enhance immunotherapy efficacy in glioblastoma through tumor microenvironment-responsive CRISPR-Cas9 nanoparticles.

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.

Green preparation of highly transparent nano-NH-UiO(Zr)-66/cellulose composite films with high-strength, superior flame retardant and UV to high-energy blue light shielding performance.

From the perspective of sustainable development and practical applications, there is a significant demand for the design of advanced cellulose-based film materials with superior mechanical, optical, and functional properties utilizing environmentally friendly strategies.

Enhanced Endothelialization Using Resveratrol-Loaded Polylactic Acid-Coated Left Atrial Appendage Occluders in a Canine Model.

Left atrial appendage occlusion (LAAO) is a well-established alternative to anticoagulation therapy for patients with atrial fibrillation who have a high bleeding risk. After occluder implantation, anticoagulation therapy is still required for at least 45 days until complete LAAO is achieved by neoendocardial coverage of the device. We applied a polylactic acid-resveratrol coating to the LAAO membrane to enhance endothelialization with the goal of shortening the anticoagulation therapy duration.

Inhibition of METTL14 overcomes CDK4/6 inhibitor resistance driven by METTL14-m6A-E2F1-axis in ERα-positive breast cancer.

CDK4/6i, the first-line drug for treating ERα-positive breast cancer, significantly improves clinical outcomes. However, CDK4/6i resistance often develops and remains a major hurdle, and the underlying mechanisms remain challenging to fully investigate. Here, we used Genome-wide CRISPR/Cas9 library screening combined with single-cell sequencing to screen for molecules mediating CDK4/6i resistance and identified METTL14 as a determinant of CDK4/6i sensitivity.

Interlaboratory variability of HER2 fluorescence in situ hybridization testing in breast cancer: results of a multicenter proficiency-testing ring study in China.

Background: Accurate detection of human epidermal growth factor receptor 2 (HER2) gene amplification via fluorescence in situ hybridization (FISH) is necessary to determine HER2 status. Although many attempts have been made to increase the consistency of the results, the actual situation still needs to be determined. To investigate the latest interlaboratory variability of HER2 FISH testing for breast cancer, a multicenter proficiency-testing ring study was conducted in China.

Targeting METTL8 with Rabdosiin overcomes lenvatinib resistance in hepatocellular carcinoma.

In hepatocellular carcinoma (HCC), lenvatinib is a key first-line treatment that significantly improves survival in some patients with advanced stage. However, lenvatinib resistance presents a major clinical challenge. This study aims to identify key molecular factors driving lenvatinib resistance in HCC and propose intervention strategies to overcome this resistance, thereby enhancing therapeutic efficacy.

Primary intracranial malignant melanoma in an adolescent girl with NRAS and TP53 mutations: case report and literature review.

Primary intracranial malignant melanoma(PIMM) is often difficult to treat in patients without a history of skin melanoma or extensive melanin deposition. Due to the rarity of the disease, the current accepted treatment is surgical resection, but the prognosis is still poor. We report a case of PIMM in an adolescent girl with epilepsy as the only symptom and atypical imaging findings.

Radiosynthesis and preclinical evaluation of a carbon-11 labeled PET ligand for imaging metabotropic glutamate receptor 7.

Metabotropic glutamate receptor 7 (mGlu) is a G protein-coupled receptor that is preferentially found in the active zone of neurotransmitter release in the central nervous system (CNS). mGlu plays a vital role in memory, learning, and neuronal development, rendering it a potential target for treating epilepsy, depression, and anxiety. The development of noninvasive imaging ligands targeting mGlu could help elucidate the functional significance of mGlu and accelerate drug discovery for neurological and psychiatric disorders.

Hydrocephalus: An update on latest progress in pathophysiological and therapeutic research.

Hydrocephalus is a severe and life-threatening disease associated with the imbalance of CSF dynamics and affects millions globally at any age, including infants. One cause of pathology that is wide-ranging is genetic mutations to post-traumatic injury. The most effective current pharmacological treatments provide only symptomatic relief and do not address the underlying pathology.

Vagus nerve electrical stimulation in the recovery of upper limb motor functional impairment after ischemic stroke.

Ischemic stroke (IS) is characterized by high mortality, disability rates, and a high risk of recurrence. Motor dysfunction, such as limb hemiparesis, dysphagia, auditory disorders, and speech disorders, usually persists after stroke, which imposes a heavy burden on society and the health care system. Traditional rehabilitation therapies may be ineffective in promoting functional recovery after stroke, and alternative strategies are urgently needed.

Research progress of epileptic seizure prediction methods based on EEG.

At present, at least 30% of refractory epilepsy patients in the world cannot be effectively controlled and treated.

In this paper, we firstly introduce the design process of EEG-based seizure prediction methods, introduce several databases commonly used in the research, and summarize the commonly used methods in pre-processing, feature extraction, classification and identification, and post-processing.

Development of a Candidate C-Labeled Selective Phosphodiesterase 1 Radioligand for Positron Emission Tomography.

Phosphodiesterases (PDEs) constitute a superfamily of phosphohydrolytic enzymes that regulate intracellular second messenger signaling by hydrolyzing cyclic adenosine monophosphate and cyclic guanosine monophosphate. Among the 11 subfamilies of PDEs, phosphodiesterase 1 (PDE1) stands out due to its broad implications in central and peripheral pathologies. There are three subtypes of PDE1: PDE1A, PDE1B, and PDE1C.
