RNA modifications are involved in many aspects of biological functions. N6-methyladenosine (m6 A) is one of the most important forms of RNA methylation and plays a vital role in regulating gene expression, protein translation, cell behaviors, and physiological conditions in many species, including humans. The dynamic and reversible modification of m6 A is conducted by three elements: methyltransferases ("writers"), such as methyltransferase-like protein 3 (METTL3) and METTL14; m6 A-binding proteins ("readers"), such as the YTH domain family proteins (YTHDFs) and YTH domain-containing protein 1 (YTHDC1); and demethylases ("erasers"), such as fat mass and obesity-associated protein (FTO) and AlkB homolog 5 (ALKBH5)...

OBJECTIVE: Deep brain stimulation (DBS) surgery has proven benefit for several movement disorders and medically-refractory psychiatric conditions and is considered a fairly safe procedure. We sought to determine the national rates, causes, predictors, and outcomes associated with 30-day and 90-day readmission. PATIENTS AND METHODS: The Nationwide Readmissions Database was queried (January-September 2013) using ICD-9-CM codes, identifying patients who underwent DBS for movement disorder (Parkinson's disease [PD], essential tremor [ET], or dystonia)...

All patients with elevated transaminases in France should be tested for HEV infection. HEV can cause severe hepatitis, in particular in patients with chronic liver disease, pregnant women and the elderly. Extra-hepatic manifestations including a number of neurologic syndromes, thrombopenia and renal injury have been described. HEV can cause chronic infection in immunosuppressed patients, in particular in organ-transplant recipients, patients with hematological malignancies and individuals with HIV. In patients with hematological malignancies, viral clearance can occur at the time of remission, with a risk of acute cytolysis and acute liver failure...

Glutathione S-tranferases (GSTs) are phase II drug metabolizing enzymes, they play crucial role in detoxification of environmental pollutants, carcinogens, drugs, xenobiotics and oxidative stress products. Genetic differences in expression and activity of GSTs are due to the existence of polymorphic alleles which encode them. Because of genetic polymorphism the GST activity has altered that lead to the increased susceptibility for toxic chemical compounds. GST genetic polymorphism is the main reason for many neurological dysfunctions...

Bisphenol A (BPA), a well-known xenoestrogen, is ubiquitously utilized in manufacturing of polycarbonated plastics. Convincing evidence suggests that BPA induces neurotoxicity and certain behavioral deficits. α-Lipoic acid (ALA) supplementation has shown protective effect against heart and liver diseases, diabetes, and neurological debility associated with aging. We studied the neuromodulatory effect of ALA against neurotoxicity of BPA in vitro in C8-D1A mouse astrocyte cell line and in vivo in C57BL/6J male mice...

OBJECTIVE: Primary progressive multiple sclerosis (PPMS) causes accumulation of neurologic disability from disease onset without clinical attacks typical of relapsing multiple sclerosis (RMS). However, whether genetic variation influences the disease course remains unclear. We aimed to determine whether mutations causative of neurologic disorders that share features with MS contribute to risk for developing PPMS. METHODS: We examined whole-genome sequencing (WGS) data from 38 PPMS and 81 healthy subjects of European ancestry...

PURPOSE OF REVIEW: Hyperglycemia occurs frequently in hospitalized patients with stroke and peripheral vascular disease (PVD). Guidelines for inpatient glycemic management are not well established for this patient population. We will review the clinical impact of hyperglycemia in this acute setting and review the evidence for glycemic control. RECENT FINDINGS: Hyperglycemia in acute stroke is associated with poor short and long-term outcomes, and perioperative hyperglycemia in those undergoing revascularization for PVD is linked to increased post-surgical complications...

BACKGROUND Paradoxical reactions to tuberculosis (TB) are clinical or radiological worsening of prior tuberculous lesions or the development of new lesions upon treatment with appropriate anti-tuberculosis therapy (ATT). This phenomenon has been described in both HIV-seropositive and HIV-seronegative patients. Although historically estimated to occur in 6-30% of HIV-seronegative patients with TB, the phenomenon is often under-recognized in the current era, particularly in countries of low TB prevalence. We describe a case of a TB paradoxical reaction affecting the CNS and spine in an HIV-seronegative individual who received clinical care in the U...

BACKGROUND: Langerhans cell histiocytosis (LCH) is a clonal disease with focal or disseminated lesions that may compress the surrounding tissues, including the spinal cord. Because few reports have described the spinal symptoms as the first manifestation of pediatric LCH, the long-term neurological outcomes remain unclear. CASE REPORT AND LITERATURE REVIEW: We report a 21-month-old boy who presented with sudden-onset paraplegia. Imaging analyses revealed that osteolytic lesions and epidural tumors compressing the spinal cord at the T7-9 vertebrae...

BACKGROUND: Several studies have recently found that oxidative stress plays a pivotal role in the pathogenesis of traumatic brain injury (TBI) and may represent a target in TBI treatment. Hydrogen-rich water was recently shown to exert neuroprotective effects in various neurological diseases through its antioxidant properties. However, the mechanisms underlying its effects in TBI are not clearly understood. The purpose of our study was to evaluate the neuroprotective role of hydrogen-rich water in rats with TBI and to elucidate the possible mechanisms underlying its effects...

A 20-y-old male intact white-faced saki monkey (Pithecia pithecia) presented with an acute ocular disease of the righteye.Clinical signs included periocular swelling, conjunctivitis, and anisocoria with a miotic right pupil. Conjunctival swabs werepositive for Human herpesvirus 1 (HHV1) according to PCR amplification with sequencing. Initial clinical signs resolvedwith supportive treatment, and the animal was managed chronically by using acyclovir (5 mg/kg PO twice daily) during flare-ups. After more than 2 y, the progression of clinical disease led to enucleation of the right eye...

BACKGROUND: Wilson's disease (WD) is an inherited disorder in which defective biliary excretion of copper leads to its accumulation, particularly in the liver and brain. Systemic lupus erythematosus (SLE) is a multi-system disorder that can manifest in any system. Cases with concomitant WD and SLE, unrelated to treatment with penicillamine, have been rarely reported. CASE PRESENTATION: We report a case of a young woman who had typical neuropsychiatric symptoms and laboratory tests results of WD...

Viscoelastic mechanical properties of the in vivo human brain, measured noninvasively with magnetic resonance elastography (MRE), have recently been shown to be affected by aging and neurological disease, as well as relate to performance on cognitive tasks in adults. The demonstrated sensitivity of brain mechanical properties to neural tissue integrity make them an attractive target for examining the developing brain; however, to date, MRE studies on children are lacking. In this work, we characterized global and regional brain stiffness and damping ratio in a sample of 40 adolescents aged 12-14 years, including the lobes of the cerebrum and subcortical gray matter structures...

Voltage-gated ion channels are critical for neuronal integration. Some of these channels, however, are misregulated in several neurological disorders, causing both gain- and loss-of-function channelopathies in neurons. Using several transgenic mouse models of Alzheimer's disease (AD), we find that sub-threshold voltage signals strongly influenced by hyperpolarization-activated, cyclic nucleotide-gated (HCN) channels progressively deteriorate over chronological aging in hippocampal CA1 pyramidal neurons. The progressively degraded signaling via HCN channels in the transgenic mice is accompanied by an age-related global loss of their non-uniform dendritic expression...

Ca2+ signaling governs a diverse range of cellular processes and, as such, is subject to tight regulation. A main component of the complex intracellular Ca2+ -signaling network is the inositol 1,4,5-trisphosphate (IP3 ) receptor (IP3 R), a tetrameric channel that mediates Ca2+ release from the endoplasmic reticulum (ER) in response to IP3 . IP3 R function is controlled by a myriad of factors, such as Ca2+ , ATP, kinases and phosphatases and a plethora of accessory and regulatory proteins. Further complexity in IP3 R-mediated Ca2+ signaling is the result of the existence of three main isoforms (IP3 R1, IP3 R2 and IP3 R3) that display distinct functional characteristics and properties...

Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) is a condition causing intense pelvic pain and urinary symptoms. While it is thought to affect millions of people and significantly impair quality of life, difficulty with diagnosis and a lack of reliably effective treatment options leave much progress to be made in managing this condition. We describe what is currently known about the immunological and neurological basis of this disease, focusing on the interactions between the immune and nervous system...
