Aims: To explore the specific molecular and cellular mechanisms of (-) - Mefloquine (one of Mefloquine's enantiomers) in modulating the interaction between Connexin 36 (Cx36) and endoplasmic reticulum stress (ERS) both in rats with CCI-induced neuropathic pain and in tunicamycin-induced ERS cells.

Materials And Methods: The authors conducted chronic constriction injury (CCI) in rats to induce neuropathic pain and established the ERS model in SH-SY5Y cells to mimic the stress state after neuropathic pain. The study employed behavioral tests and various molecular biology techniques, including Western blot analysis, cell transfection, and co-immunoprecipitation (co-IP).

Multi-scale Analysis Reveals Hippocampal Subfield Vulnerabilities to Chronic Cortisol Overexposure: Evidence from Cushing's Disease.

Background: Chronic cortisol overexposure plays a significant role in the development of neuropathological changes associated with neuropsychiatric and neurodegenerative disorders. The hippocampus, the primary target of cortisol, may exhibit characteristic regional responses due to its internal heterogeneity. This study explores structural and functional alterations of hippocampal subfields in Cushing's disease (CD), an endogenous model of chronic cortisol overexposure.

HIF-1α Mediated Regulation of Glioblastoma Malignant Phenotypes through CD47 Protein: Understanding Functions and Mechanisms.

Glioblastoma (GBM) is a highly invasive and malignant primary intracranial tumor originating from glial cells, and it is associated with an extremely poor clinical prognosis. The hypoxic conditions within GBM promote various tumor cell processes such as angiogenesis, proliferation, migration, invasion, and drug resistance. A key aspect of tumor adaptation to the hypoxic environment and the promotion of malignant behaviors is the regulation of HIF-1α signaling pathways.

ALKBH5 facilitates tumor progression via an m6A-YTHDC1-dependent mechanism in glioma.

N-methyladenosine (m6A) methylation, is a well-known epigenetic modification involved in various biological processes, including tumorigenesis. However, the role of AlkB homolog 5 (ALKBH5), a critical component of m6A modification, remains unclear in glioma. This study investigates the function of ALKBH5 in glioma progression and its potential as a therapeutic target.

Laser speckle contrast imaging with principal component and entropy analysis: a novel approach for depth-independent blood flow assessment.

Current study presents an advanced method for improving the visualization of subsurface blood vessels using laser speckle contrast imaging (LSCI), enhanced through principal component analysis (PCA) filtering. By combining LSCI and laser speckle entropy imaging with PCA filtering, the method effectively separates static and dynamic components of the speckle signal, significantly improving the accuracy of blood flow assessments, even in the presence of static scattering layers located above and below the vessel. Experiments conducted on optical phantoms, with the vessel depths ranging from 0.

SIRT2 Promotes NLRP3-Mediated Microglia Pyroptosis and Neuroinflammation via FOXO3a Pathway After Subarachnoid Hemorrhage.

Purpose: This study primarily elucidating the specific mechanism of SIRT2 on neuroinflammation and microglial pyroptosis in a mouse model of SAH.

Patients And Methods: CSF were collected from 57 SAH patients and 11 healthy individuals. C57BL/6 mouse SAH model was established using prechiasmatic cistern blood injection and the in vitro hemoglobin (Hb) stimulation microglia model.

The Epileptiogenic Modified Therapy: Regulating the Dynamic of Microglia via ROS-Responsive Cascade Nano-Formulation.

Pharmacological treatment of epilepsy presents several challenges, particularly the ineffectiveness of antiseizure medicines (ASMs) in modifying disease. In fact, the removal of reactive oxygen species (ROS) and preconditioning with tolerable dose of nitric oxide (NO) can activate neuroprotective mechanisms during latency and enhance tolerance to oxidative stress during seizures. To address this, a ROS-responsive cascade Nano-formulation (RRCN) is developed, which will transform ROS into NO.

Association between microenvironment-related genes and prognosis of primary central nervous system lymphoma.

Background: Primary central nervous system lymphoma (PCNSL) is a rare lymphoid malignancy. Systemic profiling of the PCNSL tumor microenvironment (TME) was previously conducted through gene expression analysis. We investigated the prognostic impact of TME on survival to establish novel prognostic biomarkers in PCNSL patients.

Nutritional Gender-Specific Differences in Head and Neck Cancer Patients Treated with (Chemo)Radiotherapy: Results from a Prospective Trial.

: This analysis aims to evaluate gender-specific differences in nutritional status, body weight changes, and their impact on overall survival (OS) in head and neck cancer (HNC) patients undergoing (chemo)radiotherapy (CRT). : Between 2018 and 2020, 61 HNC (17 female and 44 male) patients were prospectively recruited to receive curative (chemo)radiotherapy. Nutritional assessments included dietary questionnaire screenings and records, anthropometric methods (body mass index, BMI, body composition via bioelectrical impedance analysis (BIA)), and the determination of biomarkers like albumin and CRP.

Multi-omics analysis reveals the interplay between intratumoral bacteria and glioma.

Unlabelled: Emerging evidence highlights the potential impact of intratumoral microbiota on cancer. However, the microbial composition and function in glioma remains elusive. Consequently, our study aimed to investigate the microbial community composition in glioma tissues and elucidate its role in glioma development.

Income level is associated with differences in primary and secondary stroke prevention in China.

Introduction: The aim of this study was to assess differences in the effects of income level on the primary and secondary prevention of stroke in the Chinese population.

P1 evoked by facial expression images is enhanced in Parkinson's disease patients with depressive symptoms.

Introduction: Depressive symptoms are most common non-motor symptoms in Parkinson's disease (PD), which is often overlooked due to absence of rapid and objective diagnostic biomarkers. Electroencephalography (EEG)-based event-related potentials (ERPs) is commonly used to assess emotional processes. The aim of this study was to investigate changes in ERPs in PD patients exhibiting depressive symptoms and to provide a reliable biomarker for assisting in the diagnosis of PD with depressive symptoms.

Deciphering the CNS-glioma dialogue: Advanced insights into CNS-glioma communication pathways and their therapeutic potential.

The field of cancer neuroscience has rapidly evolved, shedding light on the complex interplay between the nervous system and cancer, with a particular focus on the relationship between the central nervous system (CNS) and gliomas. Recent advancements have underscored the critical influence of CNS activity on glioma progression, emphasizing the roles of neurons and neuroglial cells in both the onset and evolution of gliomas. This review meticulously explores the primary communication pathways between the CNS and gliomas, encompassing neuro-glioma synapses, paracrine mechanisms, extracellular vesicles, tunneling nanotubes, and the integrative CNS-immune-glioma axis.

Conversion of glioma cells into neuron-like cells by small molecules.

Currently, researchers are exploring the conversion of astrocytes into functional mature neurons and gradually exploring the conversion of glioma into neurons. We report that SLCDS (SB431542, LDN193189, CHIR99021, DAPT, and SKL2001) has been shown to convert human glioma cells into mature neuron-like cells. The converted cells exhibited upregulation of DCX, TuJ1, MAP2, NeuN, and GAD67, while the expressions of EGFR, PDGFR, Ki67, and vimentin were inhibited.
