Integrative analysis reveals the potential prognostic roles and immunological values of unc-5 netrin receptor A (UNC5A) in glioma.

Background: UNC5A had been reported to play crucial roles in multiple cancers. However, little was known about the associations among UNC5A and glioma. Therefore, we first combined scRNA-seq, proteomics, as well as bulk RNA-seq in order to investigate UNC5A's functions in gliomas.

Crucial Role of RLIP76 in Promoting Glycolysis and Tumorigenesis by Stabilization of HIF-1α in Glioma Cells Under Hypoxia.

Hypoxia is intimately associated with enhanced glycolysis in gliomas, and hypoxia-inducible factor 1α (HIF-1α) plays a critical role in this process. RLIP76 (Ral-interacting protein 76) functions as a multifunctional mediator and is aberrantly expressed in various malignant tumors, including glioma. However, the underlying mechanism of RLIP76 and HIF-1α in glioma glycolysis remains largely unclear.

Prognosis and Immune Landscapes in Glioblastoma Based on Gene-Signature Related to Reactive-Oxygen-Species.

Glioblastoma (GBM) is the most malignant and aggressive primary brain tumor and is highly resistant to current therapeutic strategies. Previous studies have demonstrated that reactive oxygen species (ROS) play an important role in the regulation of signal transduction and immunosuppressive environment in GBM. To further study the role of ROS in prognosis, tumor micro-environment (TME) and immunotherapeutic response in GBM, an ROS-related nine-gene signature was constructed using the Lasso-Cox regression method and validated using three other datasets in our research, based on the hallmark ROS-pathway-related gene sets and the Cancer Genome Atlas GBM dataset.

Anterior decompression of persistent vertebral artery occlusion caused by the cervical facet joint originated osteophyte.

Background: Persistent vertebral artery occlusion caused by compression of cervical facet joint originated osteophyte is exceptional rare. The authors sought to achieve adequate decompression of the vertebral artery (VA) with less stability decrease and movement restriction via the anterior approach, and to the authors' knowledge, no case of anterior decompression of this condition has been reported, and combination of intraoperative indocyanine green (ICG) angiography in the setting of VA decompression is also rare.

Accurately Controlled Delivery of Temozolomide by Biocompatible UiO-66-NH Through Ultrasound to Enhance the Antitumor Efficacy and Attenuate the Toxicity for Treatment of Malignant Glioma.

Background: Glioma is the most common and malignant primary brain tumour in adults and has a dismal prognosis. Temozolomide (TMZ) is the only clinical first-line chemotherapy drug for malignant glioma up to present. Due to poor aqueous solubility and toxic effects, TMZ is still inefficient and limited for clinical glioma treatment.

miRNA-193a-3p Regulates the AKT2 Pathway to Inhibit the Growth and Promote the Apoptosis of Glioma Cells by Targeting ALKBH5.

Emerging evidence indicates that microRNA (miR)-193a-3p is involved in the tumor progression of various cancers. However, the biological functions and precise molecular mechanisms of miR-193a-3p in gliomas have not been well documented. Accordingly, this study focused on the tumor suppressor role and molecular mechanisms of miR-193a-3p in glioma cells.

Facile Interfacial Synthesis of Densely Spiky Gold Nano-Chestnuts With Full Spectral Absorption for Photothermal Therapy.

The gold nanostructure is regarded as the most promising photothermal agent due to its strong localized surface plasma resonance (LSPR) effect. In particular, the gold nanostructures with sharp spikes on the surface have higher optical signal enhancement, owing to the sharp tips drastically enhancing the intense nanoantenna effect. However, current approaches for the synthesis of spiky gold nanostructures are either costly, complicated, or uncontrollable.

Increased RLIP76 expression in IDH1 wild‑type glioblastoma multiforme is associated with worse prognosis.

Mutation of the isocitrate dehydrogenase (IDH) gene is regarded a novel indicator for the prognosis of patients with glioma. However, the role of the IDH1 gene mutations in carcinogenesis and the mechanisms underlying their function in glioblastoma multiforme (GBM) remain unknown. The present study aimed to determine whether the association of RLIP76 with the different IDH1 mutational status could serve as a putative biomarker for improving disease prognosis.

A novel lncRNA-LINC01116 regulates tumorigenesis of glioma by targeting VEGFA.

Brain glioma is the most common malignant tumor of the central nervous system, and one of the leading causes of death in patients with intracranial tumors. The clinical outcome of glioma is usually poor due to abundant vascularity, fast growth and susceptibility of invasion to normal brain tissues. Our microarray study showed that lncRNA-LINC01116 was significantly upregulated in glioma tissues and played an important role in cell proliferation, cycle, migration, invasion and angiogenesis.

PomGnT1 enhances temozolomide resistance by activating epithelial-mesenchymal transition signaling in glioblastoma.

Temozolomide (TMZ) is commonly used in glioblastoma (GBM) chemotherapy. However, a great challenge for TMZ treatment is the rapid development of resistance and subsequent tumor recurrence and poor outcome. In the present study we established TMZ-resistant GBM cells (U87-TR and U251-TR) and found that the expression of PomGnT1 was significantly upregulated in TMZ-resistant GBM cells compared with the TMZ-sensitive counterparts.

Expression and functional implications of USP17 in glioma.

Glioma is the most common and malignant brain tumor with extremely poor prognosis. It is crucial to understand the molecular characteristics of glioma and find out more effective therapeutic targets for the treatment of glioma. USP17 is a novel deubiquitinating enzyme that is differentially expressed in certain types of solid tumor.

Analysis of the embolization spinal dural arteriovenous fistula and surgical treatments on 52 cases of the patients.

Background: Spinal dural arteriovenous fistula (SDAVF) highly threatens people's life and health. Effective methods for the diagnosis and treatment of the disease are badly needed in clinical application.

Objective: The objective of the present study was to sum up the diagnosis and treatment method of SDAVF to improve the diagnosis and treatment effect of the disease.

Hypoxia-induced miR-497 decreases glioma cell sensitivity to TMZ by inhibiting apoptosis.

Understanding the resistance of glioma cells to chemotherapy has been an enormous challenge. In particular, mechanisms by which tumor cells acquire resistance to chemotherapy under hypoxic conditions are not fully understood. In this study, we have found that miR-497 is overexpressed in glioma and that hypoxia can induce the expression of miR-497 at the transcriptional level by binding with the hypoxia response element in the promoter.

Up-regulation of USP2a and FASN in gliomas correlates strongly with glioma grade.

Gliomas are the most common neoplasms in the central nervous system. The lack of efficacy of glioma therapies necessitates in-depth studies of glioma pathology, especially of the underlying molecular mechanisms that transform normal glial cells into tumor cells. Here we report that a deubiquitinating enzyme, ubiquitin-specific protease 2a (USP2a), and its substrate, fatty acid synthase (FASN), are over-expressed in glioma tissue.

Which is the best peri-operative anti-coagulative therapy of transverse sinus stenting for refractory idiopathic intracranial hypertension?

We reported a refractory IIH patient who manifested with typical intracranial hypertensive symptoms successfully treated with endovascular stent implantation. Pre-operative cerebrospinal fluid (CSF) opening pressure is 36 cmH2O.

Risk factors related to dysautonomia after severe traumatic brain injury.

Background: Dysautonomia after severe traumatic brain injury (TBI) is a clinical syndrome affecting a subgroup of survivors and is characterized by episodes of autonomic dysregulation and muscle overactivity. The purpose of this study was to determine the incidence of dysautonomia after severe TBI in an intensive care unit setting and analyze the risk factors for developing dysautonomia.

Methods: A consecutive series of 101 patients with severe TBI admitted in a major trauma hospital during a 2-year period were prospectively observed to determine the effects of age, sex, mode of injury, hypertension history, admission systolic blood pressure, fracture, lung injury, admission Glasgow Coma Scale (GCS) score, injury severity score, emergency craniotomy, sedation or analgesia, diffuse axonal injury (DAI), magnetic resonance imaging (MRI) scales, and hydrocephalus on the development of dysautonomia.

Acute paraplegia following embolization of spinal dural arteriovenous fistula.

Embolization therapy has been used as the initial treatment for spinal dural arteriovenous fistula (SDAVF) only for certain patients or in certain medical institutions due to its minimal invasiveness, but the recurrence of embolization remains a clinical challenge. The recurrent patient usually exhibits a gradual onset of symptoms and progressive deterioration of neurological function. Developing paraplegia several hours after embolization is commonly seen in patients with venous thrombosis-related complications, for which anticoagulation therapy is often administered.

Prognostic influence and magnetic resonance imaging findings in paroxysmal sympathetic hyperactivity after severe traumatic brain injury.

Paroxysmal sympathetic hyperactivity (PSH) is a clinical syndrome affecting a subgroup of survivors of severe brain injury. In this study, the prevalence, magnetic resonance imaging (MRI) presentation, influence on the clinical course in the intensive care unit (ICU), and effect on neurological recovery of PSH were prospectively surveyed in 87 patients with severe traumatic brain injury (TBI). Cranial MRI was performed during the first 30 days after injury.

Expression of targeting protein for Xenopus kinesin-like protein 2 is associated with progression of human malignant astrocytoma.
