Neural stem cells (NSCs) are multipotent and undifferentiated cells with the potential to differentiate into neuronal lineages and gliocytes. NSCs have the ability to generate and regenerate the brain, indicating the possibility of cell-based therapies for neurological disorders. miR-124 has been demonstrated as a modulator in the survival, expansion, and differentiation of NSCs. However, the underlying molecular mechanisms of miR-124 in NSC development are still far from being understood. The expressions of miR-124, dishevelled binding antagonist of beta-catenin 1 (DACT1), ki-67, Nestin, β-tubulin III, glial fibrillary acidic protein (GFAP), β-catenin, cyclinD1, and glycogen synthase kinase-3β (GSK-3β) were examined by qRT-PCR or western blot...

Degenerative spine disease is a serious social problem. In most cases, it causes pain and neurological symptoms. Most patients are therefore referred for magnetic resonance imaging (MRI). The article discusses the relationship between back pain and magnetic resonance changes. The signification of some of the radiological symptoms remains controversial. Some of them are markers of acute pain, others may be clinically insignificant, occurring with age. Authors presents some of the magnetic resonance alterations and based on the latest articles discusses their clinical significance...

PURPOSE: Acute hyperglycemia in patients with traumatic brain injury correlates with a poor neurological outcome. We investigated the endothelium function of rat cerebral arterioles during acute hyperglycemia and after reducing the glucose levels using insulin. We also examined whether or not oxidative stress was involved in the cerebral arteriole response to acute hyperglycemia. METHODS: In isoflurane-anesthetized, mechanically ventilated rats, we used closed cranial window preparation to measure the changes in the pial arteriolar diameter following the topical application of acetylcholine (ACh) or adenosine...

The neurobiological basis of bipolar disorders (BD) has received increased attention and several brain regions and brain circuits have been correlated with clinical symptoms. These brain regions and circuits may represent targets for neuromodulation techniques such as transcranial Direct Current Stimulation (tDCS). We systematically reviewed the literature to explore the risks and benefits of tDCS in BD and examined all mood states. Following the PRISMA guidelines, a systematic literature search using several databases was performed from April 2002 to June 2017...

Brain-derived neurotrophic factor (BDNF) plays an important role in synaptic plasticity related to learning and memory. We previously reported that SPARC-related protein-containing immunoglobulin domains 1 (SPIG1, also known as Follistatin-like protein 4, FSTL4) binds to pro-BDNF and negatively regulates BDNF maturation; however, its neurological functions, particularly in learning and memory, have not yet been elucidated. We herein examined the electrophysiological and behavioral phenotypes of Spig1-knockout (Spig1-KO) mice...

BACKGROUND: The Glasgow Coma Scale (GCS) is an essential coma scale in critical care for determining the neurological status of patients and for estimating their long-term prognosis. Similarly, cerebral autoregulation (CA) monitoring has shown to be an accurate technique for predicting clinical outcomes. However, little is known about the relationship between CA measurements and GCS scores among neurological critically ill patients. This study aimed to explore the association between noninvasive CA multimodal monitoring measurements and GCS scores...

Dear Editor, Tuberous sclerosis (TS) is an autosomal dominant multisystem disease, which occurs due to genetically determined hyperplasia of ectodermal and mesodermal cells. Clinical manifestations present on the skin and in the nervous system, kidneys, heart, and other organs. Recent studies estimate the incidence of TS at 1/6000 to 1/10,000 live births, and a prevalence in the general population of approximately 1 in 20,000 (1). There are two different genetic loci responsible for TS: 9q34 (TSC1-hamartin) and 16p13...

Background: The natural history of multiple sclerosis (MS) typically presents with the clinically isolated syndrome (CIS), an episode of neurological symptoms caused by central nervous system inflammation or demyelination that does not fulfil the diagnostic criteria for MS. Objective: As preclinical studies have suggested that exposure to ultraviolet radiation (UVR) could regulate the development of MS, the Phototherapy for CIS (PhoCIS trial) was established to examine the effects of narrowband UVB phototherapy on patients with CIS, and their conversion to MS...

Background: Guillain-Barre' syndrome (GBS) is a serious autoimmune disorder in which the immune system attacks healthy nerve cells of the peripheral nervous system causing polyradiculoneuropathy which leads to weakness, numbness, and tingling, and can eventually cause paralysis. Autoimmune conditions like GBS can induce a high level of inflammation resulting in an increase in the C-reactive protein( CRP) production. The aim of this study is to assess the relationship between CRP level and the clinical severity as well as the electrophysiological findings of nerve conduction studies in patients with GBS...

Conversion disorder (CD) is sometimes accompanied by motor and sensory impairments, such as muscle weakness, paralysis, sensory hypersensitivity, and sensory loss. Sjögren's syndrome (SS) complicates 5-10% of cases of systemic lupus erythematosus (SLE). Patients with SS or SLE present with various neurological symptoms and psychiatric manifestations. When neurological symptoms are present, it is important to distinguish whether the symptoms are caused by a neurological or a mental disorder because the former requires early intensive intervention, such as methylprednisolone pulse therapy (MPT), whereas psychotherapy or antidepressant drugs are recommended for mental disorders...

Older adults who take analgesics for chronic pain are at increased risk for adverse drug events (ADEs). The purpose of this descriptive pilot survey was to examine how older adults self-identify analgesic ADEs, and actions they take in response to analgesic ADEs. Twenty-two community dwelling older adults with chronic pain who reported an analgesic ADE associated with their chronic pain management were interviewed and asked to describe their analgesic related ADE. Written responses were content analyzed. Nineteen opioids were reported by 15, 11 NSAIDs were reported by 8, and acetaminophen was reported by 2 older adults as associated with an ADE...

REVIEW
Bridget L Hopewell, Cristen Paige, David O Francis
Vocal tremor is a neurologic disorder with myriad etiologies (eg, Parkinson disease, medications, or essential tremor). Vocal tremor can limit intelligibility and social interaction and can result in isolation in nonprofessional voice users. In a professional singer whose entire career is based on voice quality, onset of a vocal tremor is devastating. We report a case of sudden-onset vocal tremor that impeded a young professional singer's ability to perform and record her album. The etiology was determined to be a medication side effect of lamotrigine; a reaction that has not been previously reported...
