DNA methylation is a major epigenetic mark with important roles in genetic regulation. Methylated cytosines are found primarily at CpG dinucleotides, but are also found at non-CpG sites (CpA, CpT, and CpC). The general functions of CpG and non-CpG methylation include gene silencing or activation depending on the methylated regions. CpG and non-CpG methylation are found throughout the whole genome, including repetitive sequences, enhancers, promoters, and gene bodies. Interestingly, however, non-CpG methylation is restricted to specific cell types, such as pluripotent stem cells, oocytes, neurons, and glial cells...

Epilepsy is considered as fourth most prominent neurological disorder in the world that can affect people of all age groups. Currently, around 65 million people throughout the world are suffering from epilepsy. It is evident that electroencephalograph (EEG) signals are most commonly used for detection of epileptic seizures but today many modern techniques have been developed to analyze underlying features of these EEG signals. As EEG contains a large amount of complicated information, so many researchers are trying to develop automatic systems for complete feature extraction...

Aminoacyl-tRNA synthetases (AaRSs) are ubiquitously expressed enzymes that ensure accurate translation of the genetic information into functional proteins. These enzymes also execute a variety of non-canonical functions that are significant for regulation of diverse cellular processes and that reside outside the realm of protein synthesis. Associations between faults in AaRS-mediated processes and human diseases have been long recognized. Most recent research findings strongly argue that 10 cytosolic and 14 mitochondrial AaRSs are implicated in some form of pathology of the human nervous system...

BACKGROUND: We would like to present the case of a 72-year-old woman, in whom diastematomyelia was surprisingly discovered when looking for an explanation for her neurological and urological complaints. Diastematomyelia is a rare disease in the group of 'spinal dysraphisms', mostly discovered at birth and very rare at advanced age. The clinical pattern could be seen in the general presentation of 'tethered cord' and there are 2 types of presentation with a different treatment. CASE REPORT: In our case report the two dominant complaints were pain in the right foot and sphincter problems...

A total of 10 species of Baylisascaris, a genus of ascaridoid nematodes, occur worldwide and 6 of them occur in the New World. Most of the Baylisascaris species have a similar life cycle with carnivorous mammals or marsupials serving as definitive hosts and a smaller prey host serving as paratenic (or intermediate) hosts. However, one species in rodents is unique in that it only has one host. Considerable research has been conducted on B. procyonis, the raccoon roundworm, as it is a well-known cause of severe to fatal neurologic disease in humans and many wildlife species...

Anti-N-methyl-D-aspartate receptor encephalitis is a neurological syndrome that is more common in young women and is often associated with ovarian teratoma. It is characterized by acute general unspecific symptoms that evolve to neurological deterioration, psychosis and seizures. In its more advanced stage it is associated with abnormal movements and dysautonomia.We report two cases in women of 23 and 12 years of age. Given its low incidence, we present the clinical exercise that led to their diagnoses and the treatment options employed...

Improvement of visual field defects after surgical treatment for occipital lobe epilepsy is rare. Here, the authors report on a 24-year-old man with a 15-year history of refractory epilepsy that developed after he had undergone an occipital craniotomy to remove a cerebellar astrocytoma at the age of 4. His seizures started with an elementary visual aura, followed by secondary generalized tonic-clonic convulsion. Perimetry revealed left-sided incomplete hemianopia, and MRI showed an old contusion in the right occipital lobe...

Epilepsy is one of the most common neurological disorders worldwide, with about 80 percent of cases thought to be in developing nations where it is mostly linked to superstition. Most cases of epilepsy are idiopathic, though brain injury, brain tumor, severe systemic infection and genetic mutations have been implicated in some cases. Anti-epileptic drugs (AEDs) currently in existence are not sufficient to contain the disorder. This is not only because of their limited availability and cost, but also their adverse side effects...

PURPOSE: The aim of this study was to prospectively analyze the sensitivity and specificity of routine electroencephalography with concurrent video recording (vEEG) in relation to the reasons for requesting the test and to investigate when routine vEEG should be requested. METHODS: We prospectively analyzed 1,080 consecutive vEEGs performed between April 2015 and April 2016. The requests for vEEG were classified as requests with a low suspicion of epilepsy (syncope, confusion or delirium, suspicion of psychogenic nonepileptic seizures, and paroxysmal focal neurological deficit) or requests with a high suspicion of epilepsy (first clinical seizure, suspected status epilepticus, follow-up study of a patient with epilepsy, and acute symptomatic seizures)...

Biotinidase deficiency is an autosomal recessively inherited disorder that results in the inability to recycle the vitamin, biotin. If untreated, the disorder can result in a range of neurological and cutaneous symptoms, including sensorineural deficits and deafness. To understand early mechanistic abnormalities that may precede more generalized and nonspecific effects of metabolic deficits such as weight loss and acidosis, we have analyzed auditory brainstem responses (ABRs) in biotinidase-deficient knockout (Btd (-/-) ) mice in the periweaning period with or without dietary biotin supplementation...
