Early sexual activity lowers the incidence of intracranial aneurysm: a Mendelian randomization investigation.

Objective: Investigate the potential correlation between the age of initial sexual contact, the lifetime accumulation of sexual partners, and the occurrence of intracranial aneurysm (IA) employing a two-sample Mendelian randomization approach.

Methods: This research aims to elucidate the causal relationship between intracranial aneurysm (IA) and sexual variables. Two distinct sexual variables, specifically the age had first sexual intercourse ( = 406,457) and the lifetime number of sexual partners ( = 378,882), were employed as representative parameters in a two-sample Mendelian randomization (MR) study.

Appraising the causal association among depression, anxiety and intracranial aneurysms: Evidence from genetic studies.

Background: The risk of intracranial aneurysms (IAs) is increased in individuals with depression and anxiety. This indicates that depression and anxiety may contribute to the development of physical disorders. Herein, to investigate the association between genetic variants related to depression and anxiety and the risk of IA, two-sample Mendelian randomization was performed.

DNA methylation regulator-mediated modification patterns and risk of intracranial aneurysm: a multi-omics and epigenome-wide association study integrating machine learning, Mendelian randomization, eQTL and mQTL data.

Background: Intracranial aneurysms (IAs) pose a significant and intricate challenge. Elucidating the interplay between DNA methylation and IA pathogenesis is paramount to identify potential biomarkers and therapeutic interventions.

Methods: We employed a comprehensive bioinformatics investigation of DNA methylation in IA, utilizing a transcriptomics-based methodology that encompassed 100 machine learning algorithms, genome-wide association studies (GWAS), Mendelian randomization (MR), and summary-data-based Mendelian randomization (SMR).

TSPO exacerbates acute cerebral ischemia/reperfusion injury by inducing autophagy dysfunction.

Autophagy is considered a double-edged sword, with a role in the regulation of the pathophysiological processes of the central nervous system (CNS) after cerebral ischemia-reperfusion injury (CIRI). The 18-kDa translocator protein (TSPO) is a highly conserved protein, with its expression level in the nervous system closely associated with the regulation of pathophysiological processes. In addition, the ligand of TSPO reduces neuroinflammation in brain diseases, but the potential role of TSPO in CIRI is largely undiscovered.

An immunogenic cell death-related regulators classification patterns and immune microenvironment infiltration characterization in intracranial aneurysm based on machine learning.

Background: Immunogenic Cell Death (ICD) is a novel way to regulate cell death and can sufficiently activate adaptive immune responses. Its role in immunity is still emerging. However, the involvement of ICD in Intracranial Aneurysms (IA) remains unclear.

m6A regulator-mediated RNA methylation modification patterns and immune microenvironment infiltration characterization in patients with intracranial aneurysms.

Background: The role of epigenetic modulation in immunity is receiving increased recognition-particularly in the context of RNA N6-methyladenosine (m6A) modifications. Nevertheless, it is still uncertain whether m6A methylation plays a role in the onset and progression of intracranial aneurysms (IAs). This study aimed to establish the function of m6A RNA methylation in IA, as well as its correlation with the immunological microenvironment.

Modification Patterns of DNA Methylation-Related lncRNAs Regulating Genomic Instability for Improving the Clinical Outcomes and Tumour Microenvironment Characterisation of Lower-Grade Gliomas.

DNA methylation is an important epigenetic modification that affects genomic instability and regulates gene expression. Long non-coding RNAs (lncRNAs) modulate gene expression by interacting with chromosomal modifications or remodelling factors. It is urgently needed to evaluate the effects of DNA methylation-related lncRNAs (DMlncRNAs) on genome instability and further investigate the mechanism of action of DMlncRNAs in mediating the progression of lower-grade gliomas (LGGs) and their impact on the immune microenvironment.

Effect of endovascular treatment on high-risk patients with chronic carotid artery occlusion.

Objective: This study aims to discuss the safety and short-term efficacy of endovascular treatment on high-risk patients with chronic carotid artery occlusion.

Methods: A retrospective analysis was performed on the clinical data of 16 high-risk patients with chronic carotid artery occlusion who received endovascular treatment at the Department of Neurosurgery of the First Affiliated Hospital of Xinjiang Medical University from November 2013 to July 2016. The incidence of adverse events at 1 week, 30 days and six months post-operation were observed, and NIHSS was adopted to assess the neurological function of patients six months before and after the operation.

A histopathologic diagnosis of brain lymphangiomyoma, clinically misdiagnosed as simple angiomyxoma: case report.

Introduction: Lymphangioleiomyomatosis (LAM) is a rare disease which affects women of reproductive age almost exclusively as one of the most gender-specific diseases, and which can occur at any site in the body but most commonly in the lungs. Here we report a rare case of recurrent brain lymphangiomyoma which was misdiagnosed as angiomyxoma.

Case Presentation: A 28-year-old male complained of finding a recurrent mass at the right temporal lobe of his brain for the last 4 months.

Operative managements of extracranial carotid artery aneurysms: a report of three cases and literature review.

Background: The purpose of this study is to report the treatment approaches and postoperative outcomes of extracranial carotid artery aneurysms (ECAAs) and discuss the symptoms, related risk factors, etiology, diagnostic methods, treatments, and follow-up period complications.

Case Presentation: We describe three patients with symptomatic extracranial carotid artery aneurysms; one of them was treated with end-to-end anastomosis of the extracranial internal carotid artery (EICA) after the resection of the aneurysm, while the other two patients were deployed with Willis covered stents in the extracranial internal carotid artery. All of the patients were in good condition when discharged home.

Arctigenin, a natural lignan compound, induces G/G cell cycle arrest and apoptosis in human glioma cells.

The aim of the current study was to investigate the anticancer potential of arctigenin, a natural lignan compound, in malignant gliomas. The U87MG and T98G human glioma cell lines were treated with various concentrations of arctigenin for 48 h and the effects of arctigenin on the aggressive phenotypes of glioma cells were assessed. The results demonstrated that arctigenin dose-dependently inhibited the growth of U87MG and T98G cells, as determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and bromodeoxyuridine incorporation assays.
