OBJECTIVES: Parkinson's disease (PD) is a progressive neurological disorder associated with motor disabilities and cognitive dysfunction as well. Evidence indicates that PD occurs less frequently in women than men, confirming a role for steroid hormones in protection of dopaminergic nigrostriatal neurons. It is reported that soy genistein, an estrogen agonist phytoestrogen, display neuroprotective effects against neuronal death. In this study we evaluated the effect of genistein in animal models of Parkinsonism (P) and Parkinsonism + ovariectomized (OP)...

INTRODUCTION: Admission to the intensive care unit (ICU) may be preceded by dramatic events leading to permanent neurological injury. Plasma S100 protein levels are proved to be clinically useful in predicting neurological outcome following cardiac arrest. It is unclear, however, whether this may be extrapolated to a broader population of ICU patients. AIM: To assess the utility of plasma S100 protein in predicting death, permanent neurological damage, or unfavourable outcome at admission to the intensive care unit...

BACKGROUND: Previous studies reported that the mild hypothermia therapy (MHT) could significantly improve the clinical outcomes for patients with hypertensive intracerebral hemorrhage (HICH). Therefore, this meta-analysis was conducted to systematically assess whether the addition of local MHT (LMHT) could significantly improve the efficacy of minimally invasive surgery (MIS) in treating HICH. METHODS: Randomized clinical trials on the combined application of MIS and LMHT (MIS+LMHT) vs MIS alone for treating HICH were searched up to September 2016 in databases...

The present study was composed of two parts examining the clinical utility of the Delis-Kaplan Executive Function System (D-KEFS) Verbal Fluency and Color-Word subtests in traumatic brain injury (TBI). In the first part, the performance of 128 outpatients with mild to severe TBI on the Verbal Fluency and Color-Word subtests was examined in relation to two primary indicators of TBI severity: length of coma and the presence of intracranial lesions on neuroimaging through regression analysis. After controlling for education, ethnicity, and complicating premorbid and comorbid factors, length of coma predicted performance on the Color-Word Inhibition/Switching subtest, whereas the presence of diffuse lesions was related to Verbal Fluency Category Switching performance...

N-methyl-D-aspartate receptors (NMDARs), ligand-gated ionotropic glutamate receptors, play key roles in normal brain development and various neurological disorders. Here we use standing variation data from the human population to assess which protein domains within NMDAR GluN1, GluN2A and GluN2B subunits show the strongest signal for being depleted of missense variants. We find that this includes the GluN2 pre-M1 helix and linker between the agonist-binding domain (ABD) and first transmembrane domain (M1). We then evaluate the functional changes of multiple missense mutations in the NMDAR pre-M1 helix found in children with epilepsy and developmental delay...

BACKGROUND: Despite the benefits of whole-body hypothermia therapy, many infants with hypoxic-ischemic encephalopathy (HIE) die or have significant long-term neurodevelopmental impairment. Prospectively identifying neonates at risk of poor outcome is essential but not straightforward. The cerebellum is not classically considered to be a brain region vulnerable to hypoxic-ischemic insults; recent literature suggests, however, that the cerebellum may be involved in neonatal HIE. In this study, we aimed to assess the microstructural integrity of cerebellar and linked supratentorial structures in neonates with HIE compared to neurologically healthy neonatal controls...

PURPOSE: Lingering neurologic injury after concussion may expose athletes to increased risk if return-to-play is premature. We explored whether on-field performance after concussion is a marker of lingering neurologic injury. METHODS: Retrospective cohort study on 1,882 skill-position players who played in the National Football League (NFL) during 2007-2010. Players with concussion based on the weekly injury report, were compared to players with other head and neck injuries (controls) on measures of on-field performance using Football Outsiders' calculation of Defense-Adjusted Yards Above Replacement (DYAR): a measure of a player's contribution controlling for game context...

BACKGROUND: Sickle cell disease is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. Sickle cell disease can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Stroke affects around 10% of children with sickle cell anaemia (HbSS). Chronic blood transfusions may reduce the risk of vaso-occlusion and stroke by diluting the proportion of sickled cells in the circulation...

Pre-operative anxiety is an unpleasant state of psychological distress that occurs in up to 87% of patients awaiting neurosurgical procedures. Sedative medication is undesirable in this population due to the need for early postoperative neurological assessment. Acupuncture has previously been shown to reduce pre-operative anxiety, but studies involving neurosurgical patients are lacking. This single-centre, prospective, randomised controlled trial was designed to determine the effect of acupuncture at the EX-HN3 (Yintang point) on pre-operative anxiety levels in neurosurgical patients...
