Background: The ubiquitin-proteasome pathway controls the monitoring and degradation of important proteins and is involved in several cellular processes, such as development, differentiation, and transcriptional regulation. Recent evidence has shown that ubiquitin carboxy-terminal hydrolase-L1 (UCH-L1), a member of the deubiquitinating enzyme family that removes ubiquitin from protein substrates, is overexpressed in many types of cancer.
Aim: This study thus examined the expression of UCH-L1 in human astrocytoma tissues.
Spine fractures are most commonly observed among older people due to weak bones and irregular postures. These fractures of 10 lead to coccygodynia. Women are 5 times more prone to developing coccygodynia as compared to men.

Searches for "coccydynia, coccyx trauma, coccyx fracture" were carried out in the 3 most used search engines in the USA: Google, Yahoo, and Bing in February 2022. A total of 141 websites were rated by 2 different neurosurgeons for the "Global Quality Score" and "Alexa Popularity Rank.

However, there is limited knowledge about the neuropsychological profile of vitamin D deficiency-related cognitive deficits and their underlying molecular mechanisms. As an inductor of cytochrome P450 3A4, a lack of vitamin D might aggravate cognitive deficits by increased exposure to anticholinergic antipsychotics.

For many reasons, vitamin D supplementation may be indicated for this patient cohort. However, there is growing evidence for a vitamin D-mediated increase of drug metabolism by induction of cytochrome P450 (CYP) 3A4.

The secondary damage mechanism is a mainstay process, and it starts within a few minutes after trauma. We aim to investigate the neuroprotective effects of milrinone on the SCI model.

Background: Adalimumab (ADA), which is a new-generation recombinant human monoclonal antibody for tumor necrosis factor α (TNFα), has strong anti-inflammatory effects. The role of enhanced inflammation is well established for the development and progression of cerebral vasospasm. Investigated in the present study is the probable ameliorating and neuroprotective effects of ADA in rabbits using a cerebral vasospasm model with biochemical and histopathological methods.

Methods: In this cohort study, the European Health Literacy Survey Questionnaire (HLS-EU- Q47) scores as a measure of health literacy were compared among the two groups of patients who accepted to undergo surgery for SUI and the ones who did not. Demographic features, weight and BMI values, comorbidity, menopausal status, duration and type of UI, socioeconomic characteristics (marital status, educational level, level of income) and HLS-EU- Q47 survey results of the two groups were compared.

Objective: Missed abortion occurs in ∼ 15% of all clinical pregnancies. The pathogenesis is not clearly known. However, defective placentation resulting in maternal systemic inflammatory response is considered responsible for missed abortion.

Background: In this study, we aim to evaluate the potential effects of methylprednisolone on the neurological outcome of spinal cord injury (SCI) patients with thoracolumbar junction (T10-L1) spine fractures.
Methods: The data from 182 SCI patients who sustained a thoracolumbar junction spine fracture were operated by us between September 2008 to January 2015 were analysed retrospectively. The patients were divided into two groups: Group 1 underwent methylprednisolone treatment in conjunction with early surgical intervention, while group 2 underwent only early surgical intervention without methylprednisolone treatment.
Objectives: We aimed to evaluate neuroprotective effects of tocilizumab on spinal cord ischemia-reperfusion (I/R) injury. Our study design was an experimental rabbit spinal cord I/R injury model, and the setting was at the Animal Research Laboratory, Necmettin Erbakan University, Meram School of Medicine, Konya, Turkey.
Methods: Twenty-four adult New Zealand rabbits were randomly divided into 3 groups: Group 1, control group (n = 8); Group 2, I/R group, and Group 3 (n = 8) I/R injury + tocilizumab (4 mg/kg, ip) treatment group.

Material And Methods: Surgically resected human glioblastoma samples from 40 patients who underwent surgery at our institution were extracted from their histopathological specimens and divided into three groups. Ten histopathologically regular cerebral tissue samples, acquired from the non-neoplastic portion of the specimens, were assigned as the control group.
The present study was designed to evaluate the expression of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and thioredoxin reductase 1 (TrxR1) in glioblastoma multiforme (GBM) with and without intratumoral hemorrhage. Surgically resected human GBM samples from 20 patients who underwent surgery at our institute were extracted from the histopathological specimens and divided into two groups. A total of 10 samples from each type of GBM (World Health Organization grade IV, intratumoral hemorrhage-positive or -negative) were included in each group.

SAH-induced cerebral vasospam alters thioredoxin (Trx) cycle enzymes and thioredoxin-interacting protein (TXNIP) as an important endogenous antioxidant system. In this study, we have explored the effects of telmisartan on the vascular morphological changes, endothelial apoptosis, tissue oxidative stress status and the level of Trx cycle enzymes/ TXNIP in a rabbit SAH model.

Choroid plexus papillomas (CPPs) are relatively rare neuroectodermal tumors that develop from choroid plexus epithelial cells and are usually restricted to the ventricles. Extraventricular CPPs are very unusual and can be difficult to diagnose and treat. A 50-year-old male patient was admitted to our clinic complaining of headache and visual deterioration.

The aim of the present study was to investigate morphometric analyses of the sacral canal, hiatus, and surrounding structures according to different age groups and gender by using the "multidetector computed tomography" method.
Material And Methods: Multiplanar-reconstructed images from 300 adult (150 females and 150 males, between 20 and 80 years old) were divided into three groups according to age and retrospectively examined.
Background: Experimental approaches have been promising with the use of therapeutic hypothermia after Traumatic Brain Injury (TBI) whereas clinical data have not supported its efficacy.
Objectives: This study aimed to investigate whether using selective deeper brain cooling correlates with a more neuroprotective effect on Intracranial Pressure (ICP) increments following TBI in rats.
Materials And Methods: Adult male Sprague-Dawley rats (mean weight = 300 g; n = 25) were subjected to brain injury using a modified Marmarou method.
Spontaneous "non-moyamoya" arterial occlusion of the intracranial arteries is very unusual. Progressive occlusion of a major intracranial artery, independently from the etiology, can lead to the development of collateral arterial networks that supply blood flow to distal territories beyond the occlusion. These collateral arteries are typically small and conduct low flows, but the hemodynamic stress within them can lead to aneurysm formation within the collateral network.
