OBJECTIVES: Alzheimer's disease (AD) is the most common cause of dementia in elderly persons. Since the pathology of AD develops slowly from a preclinical or early phase into a fully expressed clinical syndrome, at the time of diagnosis the disease has been progressing for many years. To facilitate the early diagnosis of AD, we performed protein profiling of blood in patients with mild AD as defined by the Functional Assessment Staging (FAST) scale. METHODS: Plasma samples from mild AD patients and healthy controls were analyzed using two-dimensional differential gel electrophoresis (2D-DIGE) combined with matrix-assisted laser desorption ionization time-of-flight tandem mass spectrometry (MALDI-TOF/TOF/MS) followed by peptide mass fingerprinting...

Radiofrequency electromagnetic field (RF-EMF) is used globally in conjunction with mobile communications. There are public concerns of the perceived deleterious biological consequences of RF-EMF exposure. This study assessed neuronal effects of RF-EMF on the cerebral cortex of the mouse brain as a proxy for cranial exposure during mobile phone use. C57BL/6 mice were exposed to 835 MHz RF-EMF at a specific absorption rate (SAR) of 4.0 W/kg for 5 hours/day during 12 weeks. The aim was to examine activation of autophagy pathway in the cerebral cortex, a brain region that is located relatively externally...

BACKGROUND AND PURPOSE: Estimates of cumulative CT/CTA radiation dose based on volumetric CT dose index have raised concern that neurological intensive care unit patient exposures may reach thresholds for deterministic skin injury. Because the accuracy of volumetric CT dose index for this purpose in unknown, we set out to directly measure head CT and CTA peak skin dose, assess the relationship of volumetric CT dose index to measured peak skin dose, and determine whether multiple CT/CTA exposures in typical patients in the neurological intensive care unit produce cumulative doses approaching or exceeding single-dose deterministic thresholds for skin injury...

BACKGROUND: Oxaliplatin is a chemotherapy agent active against digestive tumors. Peripheral neuropathy is one of the most important dose-limiting toxicity of this drug. It occurs in around 60-80% of the patients, and 15% of them develop severe neuropathy. The pathophysiology of oxaliplatin neurotoxicity remains unclear. SCN9A is a gene codifying for a subtype sodium channel (type IX, subunit α) and mutations in this gene are involved in neuropathic perception. In this study we investigated whether SCN9A genetic variants were associated with risk of neurotoxicity in patients diagnosed of cancer on treatment with oxaliplatin...

The capacity to flexibly respond to contextual changes is crucial to adapting to a dynamic environment. Compulsivity, or behavioural inflexibility, consists of heterogeneous subtypes with overlapping yet discrete neural substrates. The subthalamic nucleus (STN) mediates the switch from automatic to controlled processing to slow, break or stop behaviour when necessary. Rodent STN lesions or inactivation are linked with perseveration or repetitive, compulsive responding. However, there are few studies examining the role of latent STN-centric neural networks and compulsive behaviour in healthy individuals...

QUESTION: Acute headache is a main reason for emergency consultations and can be a symptom of dangerous neurological conditions. We hypothesised that in medical walk-in headache patients with low suspicion of intracranial bleeding significant findings in brain magnetic resonance imaging (MRI) are associated with clinical features. METHODS: Retrospective chart review on medical outpatient referrals for brain MRI (2010-2014) with the chief complaint "acute headache" (duration <4 weeks)...

BACKGROUND AND IMPORTANCE: Amputation neuromas consist of non-neoplastic collections of myelinated axons and Schwann cells and typically arise in injured peripheral nerves. Rarely, however, neuromas occur within the spinal cord. Intramedullary amputation neuromas have been described both with and without a history of trauma within the peripheral nervous system. We report a rare case of an isolated intramedullary spinal cord amputation neuroma. CLINICAL PRESENTATION: This 43-year-old man presented with progressive and severe gait deterioration for ~ 7 years...

PURPOSE OF REVIEW: Herpes simplex virus encephalitis (HSVE) is often associated with significant morbidity and mortality, and despite appropriate treatment with antivirals, worsening of neurological symptoms or relapse occurs in a subset of patients. Recent data suggests that many relapses are likely caused by a secondary immune response, with the N-methyl-D-aspartate receptor (NMDAR) antibody being the most commonly associated autoantibody. We provide a review of the relevant literature, examining the relationship between HSVE and development of autoimmunity...

We previously found that hematoma worsens hydrocephalus after intraventricular hemorrhage (IVH) via increasing iron deposition and aggravating ependymal cilia injury; therefore, promoting hematoma absorption may be a promising strategy for IVH. Recently, some investigations imply that simvastatin has the ability of accelerating hematoma absorption. Thus, this study was designed to examine the efficacy of simvastatin for IVH in rats. Intracerebral hemorrhage with ventricular extension was induced in adult male Sprague-Dawley rats after autologous blood injection...

Microglia activation has been implicated in the pathogenesis of many neurological diseases. These reactive microglia are capable of producing a variety of proinflammatory mediators and potentially neurotoxic compounds. The increase of cell number and expression of CD11b are the main features of activated microglia. In this study, we examined the suppressive effects of CDK11p58 on microglia activation induced by lipopolysaccharide (LPS) in vitro. We found that in the activated microglia, the expression of CDK11p58 increased and the overexpression of CDK11p58 could reduce the increased proliferation and CD11b expression in LPS-activated microglia...

Migraine is a recurring, episodic neurological disorder characterized by headache, nausea, vomiting, and sensory disturbances. These events are thought to arise from the activation and sensitization of neurons along the trigemino-vascular pathway. From animal studies, it is known that thalamocortical projections play an important role in the transmission of nociceptive signals from the meninges to the cortex. However, little is currently known about the potential involvement of cortico-cortical feedback projections from higher-order multisensory areas and/or feedforward projections from principle primary sensory areas or subcortical structures...

BACKGROUND: Primary orthostatic tremor is a rare disorder that is still under-diagnosed or misdiagnosed. Motor symptoms are fairly characteristics but the real impact on the patient's every day life and quality of life is under-estimated. The "how my patients taught me" format describes the impact on the patients' every day life with their own words, which is rarely done. CASE PRESENTATION: A 46 year old lady was diagnosed primary orthostatic tremor (POT) based on the cardinal symptoms: feelings of instability, leg tremor and fear of falling in the standing position, improvement with walking and disappearance while sitting, frequency of Tremor in the 13-18Hz range, normal neurological examination...

Nucleic acid-editing enzymes of the apolipoprotein B mRNA-editing enzyme (APOBEC) family have been associated with somatic mutation in cancer. However, the role of APOBEC catalytic subunit 3B (APOBEC3B) editing in the pathogenesis of base substitutions in meningiomas is unknown. In the present study, the expression of APOBEC3B was examined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot analyses in five fetal and one adult human leptomeninges and 38 meningiomas. Genomic DNA was sequenced using the Illumina Tru-Seq Cancer Panel...
