Demyelination is the cause of disability in various neurological disorders. It is therefore crucial to understand the molecular regulation of oligodendrocytes, the myelin forming cells in the CNS. Growth factors are known to be essential for the development and maintenance of oligodendrocytes and are involved in the regulation of glial responses in various(More)
Triple-negative breast cancer (TNBC) is a high medical need disease with limited treatment options. CD8+ T cell-mediated immunotherapy may represent an attractive approach to address TNBC. The objectives of this study were to assess the expression of CXorf61 in TNBCs and healthy tissues and to evaluate its capability to induce T cell responses. We show by(More)
Acute hemorrhagic leukoencephalitis is a fulminant demyelinating disease and commonly considered as a rare and severe variant of acute disseminated encephalomyelitis. Here, we report the clinical, magnetic resonance imaging, and brain biopsy findings of a 35-year-old female with relapsing-remitting multiple sclerosis, who developed acute hemorrhagic(More)
The majority of patients presenting with a first clinical symptom suggestive of multiple sclerosis (MS) do not fulfill the MRI criteria for dissemination in space and time according to the 2010 revision of the McDonald diagnostic criteria for MS and are thus classified as clinically isolated syndrome (CIS). To re-evaluate the utility of cerebrospinal fluid(More)
Chronic mucocutaneous candidiasis, characterized by persistent or recurrent fungal infections, represents the clinical hallmark in gain-of-function (GOF) signal transducer and activator of transcription 1 (STAT1) mutation carriers. Several cases of intracranial aneurysms have been reported in patients with GOF STAT1 mutation but the paucity of reported(More)
BACKGROUND MiRNA-181c, miRNA-633 and miRNA-922 have been reported to be deregulated in multiple sclerosis. OBJECTIVES To investigate the association between miRNA-181c, miRNA-633 and miRNA-922 and conversion from clinically isolated syndrome (CIS) to relapsing-remitting multiple sclerosis (RRMS); and to compare microRNAs in cerebrospinal fluid (CSF) and(More)
Several studies have reported that patients with essential tremor (ET) may also have mild cognitive impairment. Event-related potentials (ERPs) involve cognitive processes in the brain. No detailed investigation has been conducted into auditory ERPs (AERPs) to detect the subclinical cognitive dysfunction in patients with ET. Therefore, this study aimed to(More)
INTRODUCTION In this study, we aimed to determine the changes in quality of life of children/adolescents with anxiety disorders during six months of sertraline treatment, to investigate parent-child/adolescent concordance in perception of quality of life and to examine the effect of treatment on children/adolescents. METHODS In this study, 30 patients(More)
The aim of this study was to investigate the relationship between prostate specific antigen density and prostate volume with microvessel density in patients with benign prostatic hyperplasia and advanced prostatic carcinoma. Sixty-eight patients with benign prostatic hyperplasia and 11 patients with advanced prostatic carcinoma participated in the study.(More)
CSF abnormalities have been reported in CSF leakage syndrome. However, the mechanism for these CSF changes is actually unknown and they may indicate impaired CSF flow or blood-CSF barrier. Angiopoietin-2 (Ang-2), a protein which is expressed and released by endothelial cells, has been associated with increased vascular permeability. In the assumption that(More)
