Introduction: Glioblastoma is the most common and aggressive brain tumor, with low survival rates and high recurrence rates. Therefore, it is crucial to understand the precise molecular mechanisms involved in the oncogenesis of glioblastoma.

Material And Methods: To investigate the regulatory mechanisms of long non-coding RNA (lncRNA)-microRNA (miRNA)-messenger RNA (miRNA) network related to glioblastoma, in the present study, a comprehensive analysis of the genomic landscape between glioblastoma and normal brain tissues from the Gene Expression Omnibus (GEO) dataset was first conducted to identify differentially expressed genes (DEGs) in glioblastoma.

In this work, aptamer AD1-modified poly(lactic--glycolic acid)-poly(ethylene glycol)-fluconazole nanoparticles (AD1-PLGA-PEG-FLUCZ) were prepared, enabling the antifungal drug FLUCZ to specifically target the biofilm of , prolonging its action time on the biofilm, and enhancing its killing effect. The analytical results demonstrated that the AD1-PLGA-PEG-FLUCZ nanoparticulate system achieved a FLUCZ loading capacity of 5.89 ± 0.

Postoperative recurrence of glioblastoma (GBM) is a key contributing factor to the unfavorable prognosis of patients. Chemotherapy has been extensively employed as a postoperative treatment for GBM; however, the produced drug resistance significantly undermines the chemotherapeutic efficacy. Herein, a multifunctional system based on magnesium micromotor (Mg-Motor-DOX) is designed and fabricated that can generate hydrogen gas in situ and actively deliver the chemotherapeutic drug doxorubicin (DOX).

Gliomas, including both glioblastoma multiforme (GBM) and lower-grade glioma (LGG), present a substantial challenge in neuro-oncology because of genetic heterogeneity and unsatisfactory prognosis. This study aimed to conduct a comprehensive multi-omics analysis of gliomas using various bioinformatics approaches to identify potential therapeutic targets and prognostic markers. A comprehensive analysis was conducted on 1327 sequencing data samples alongside their relevant clinical information sourced from The Cancer Genome Atlas (TCGA) pertaining to glioblastoma (GBM), low-grade glioma (LGG), the Chinese Glioma Genome Atlas (CCGA) and University of California Santa Cruz Xena (UCSC Xena) datasets.

The carcinogen ethyl carbamate (EC) in food is a potential threat to health. Available urethanases cannot efficiently degrade EC because of their instability or low activity under acidic conditions. Here, a novel thermostable urethanase was identified in Thermoflavimicrobium dichotomicum using a database-mining approach.

Article Synopsis
  • Cronkhite-Canada syndrome (CCS) is a rare condition in children that often goes misdiagnosed due to its complex symptoms.
  • A case study of a 13-year-old boy highlighted symptoms like persistent diarrhea, vomiting, weight loss, alopecia, and skin changes, with lab tests revealing specific autoimmune indicators.
  • The study concludes that thorough assessments, including endoscopic and histological evaluations, are crucial for diagnosing CCS, and treatment with steroids like prednisone can significantly improve symptoms.

Phospholipase A1 (PlaA) plays a pivotal role in diverse applications within the food and biochemical medical industries. Herein, we investigate the impact of the accessory protein encoded by plaS from Serratia marcescens on PlaA activity in Escherichia coli. Notably, PlaS demonstrates the ability to enhance PlaA activity while concurrently exhibiting inhibitory effects on the growth of E.

Tumor recurrence remains the leading cause of treatment failure following surgical resection of glioblastoma (GBM). M2-like tumor-associated macrophages (TAMs) infiltrating the tumor tissue promote tumor progression and seriously impair the efficacy of chemotherapy and immunotherapy. In addition, designing drugs capable of crossing the blood-brain barrier and eliciting the applicable organic response is an ambitious challenge.

In order to excavate microbial epoxide hydrolases (EHs) with desired catalytic properties, a novel EH, SfEH1, was identified based on the genome annotation of Streptomyces fradiae and sequence alignment analysis with local protein library. The SfEH1-encoding gene, sfeh1, was then cloned and over-expressed in soluble form in Escherichia coli/BL21(DE3). The optimal temperature and pH of recombinant SfEH1 (reSfEH1) and reSfEH1-expressing E.

Introduction: Glioblastoma is a primary intracranial tumour with extremely high disability and fatality rates among adults. Existing diagnosis and treatment methods have not significantly improved the overall poor prognosis of patients. Nifuroxazide, an oral antibiotic, has been reported to act as a tumour suppressor in a variety of tumours and to participate in the process of antitumour immunity.

Diagnosis of primary brain tumors relies heavily on histopathology. Although various computational pathology methods have been developed for automated diagnosis of primary brain tumors, they usually require neuropathologists' annotation of region of interests or selection of image patches on whole-slide images (WSI). We developed an end-to-end Vision Transformer (ViT) - based deep learning architecture for brain tumor WSI analysis, yielding a highly interpretable deep-learning model, ViT-WSI.

A novel La-Co-O-C (LC-C) composites were prepared via a facile co-hydrothermal route with oxides and glycerol and further optimized for methane catalytic activity and thermal stability via component regulation. It was demonstrated that CoO phase was the main component in regulation. The combined results of X-ray photoelectron spectroscopy (XPS), temperature-programmed desorption of oxygen (O-TPD), temperature-programmed reduction of hydrogen (H-TPR), temperature-programmed desorption of ammonia/carbon dioxide (NH/CO-TPD) revealed that component regulation led to more oxygen vacancies and exposure of surface Co, lower surface basicity and optimized acidity, which were beneficial for adsorption of active oxygen species and activation of methane molecules, resulting in the excellent catalytic oxidation performance.

Polyphenols are secondary plant metabolites or organic compounds synthesized by them. In other words, these are molecules that are found in plants. Due to the wide variety of polyphenols and the plants in which they are found, these compounds are divided according to the source of origin, the function of the polyphenols, and their chemical structure; where the main ones are flavonoids.

Gliomas are the most common and malignant primary tumors of the central nervous system (CNS). Glioblastomas are the most malignant and aggressive form of primary brain tumors and account for the majority of brain tumor-related deaths. The current standard treatment for gliomas is surgical resection supplemented by postoperative chemotherapy.

The natural product pectolinarigenin exerts anti-inflammatory activity and anti-tumor effects, and exhibits different biological functions, particularly in autophagy and cell cycle regulation. However, the antineoplastic effect of pectolinarigenin on glioblastoma (GBM) remains unclear. In the present study, we found that pectolinarigenin inhibits glioblastoma proliferation, increases autophagic flux, and induces cell cycle arrest by inhibiting ribonucleotide reductase subunit M2 (RRM2), which can be reversed by RRM2 overexpression plasmid.
