#1
T A Blair, S F Moore, T G Walsh, J L Hutchinson, T N Durrant, K E Anderson, A W Poole, I Hers
Phosphoinositide 3-kinase (PI3K) plays an important role in platelet function and contributes to platelet hyperreactivity induced by elevated levels of circulating peptide hormones, including thrombopoietin (TPO). Previous work established an important role for the PI3K isoform; p110β in platelet function, however the role of p110α is still largely unexplored. Here we sought to investigate the role of p110α in TPO-mediated hyperactivity by using a conditional p110α knockout (KO) murine model in conjunction with platelet functional assays...

The direct utilization of metallic lithium and sodium as the anodes for rechargeable batteries would be highly advantageous, which has been considered as one of the most promising choices for next-generation high-energy-density storage devices. Although the induced safety concerns, inferior rate and cycling performance severely hinder the commercialization of lithium-metal batteries (LMB) and sodium-metal batteries (SMB), the recent development of nanotechnology-based solutions really revives the lithium/sodium metal anodes for high-energy batteries...

OBJECTIVE: To define a disorder characterized by recurrent spontaneous vertigo (RSV) of unknown etiology and interictal headshaking nystagmus (HSN). METHODS: We characterized HSN in 35 patients with RSV-HSN compared to that recorded in randomly selected patients with compensated vestibular neuritis (VN), vestibular migraine (VM), and Ménière disease (MD). RESULTS: The estimated time constant (TC) of the primary phase of HSN was 12 seconds (95% confidence interval [CI] 12-13) in patients with RSV-HSN, which was larger than those in patients with VN (5 seconds, 95% CI 4-5), VM (5 seconds, 95% CI 5-6), or MD (6 seconds, 95% CI 5-6)...

BACKGROUND: While the neuroanatomic substrates of symptoms of attention deficit hyperactivity disorder (ADHD) have been investigated, less is known about the neuroanatomic correlates of cognitive abilities pertinent to the disorder, particularly in adults. Here we define the neuroanatomic correlates of key cognitive abilities and determine if there are associations with histories of psychostimulant medication. METHODS: We acquired neuroanatomic magnetic resonance imaging data from 264 members of 60 families (mean age 29...

BACKGROUND: There is growing concern that phthalate exposures may have an impact on child neurodevelopment. Prenatal exposure to phthalates has been linked with externalizing behaviors and executive functioning defects suggestive of an attention-deficit hyperactivity disorder (ADHD) phenotype. OBJECTIVES: We undertook an investigation into whether prenatal exposure to phthalates was associated with clinically confirmed ADHD in a population-based nested case-control study of the Norwegian Mother and Child Cohort (MoBa) between the years 2003 and 2008...

Premature T cell immunosenescence with CD57+ CD8+ T cell accumulation has been linked to immunodeficiency and autoimmunity in primary immunodeficiencies including activated PI3 kinase delta syndrome (APDS). To address whether CD57 marks the typical senescent T cell population seen in adult individuals or identifies a distinct population in APDS, we compared CD57+ CD8+ T cells from mostly pediatric APDS patients to those of healthy adults with similarly prominent senescent T cells. CD57+ CD8+ T cells from APDS patients were less differentiated with more CD27+ CD28+ effector memory cells showing increased PD1 and Eomesodermin expression...

REVIEW
Rodrigo Iturriaga
PURPOSE OF REVIEW: An abnormal heightened carotid body (CB) chemoreflex, which produces autonomic dysfunction and sympathetic overactivation, is the common hallmark of obstructive sleep apnea (OSA), resistant hypertension, systolic heart failure (HF), and cardiometabolic diseases. Accordingly, it has been proposed that the elimination of the CB chemosensory input to the brainstem may reduce the autonomic and cardiorespiratory alterations in sympathetic-associated diseases in humans. RECENT FINDINGS: A growing body of evidence obtained in preclinical animal models support that an enhanced CB discharge produces sympathetic hyperactivity, baroreflex sensitivity and heart rate variability impairment, breathing instability, hypertension, and insulin resistance...

We designed a study to investigate the patterns of the steady-state visual evoked potential (SSVEP) and auditory steady-state response (ASSR) in adolescents with attention-deficit/hyperactivity disorder (ADHD) when performing a motor response inhibition task. Thirty 12- to 18-year-old adolescents with ADHD and 30 healthy control adolescents underwent an electroencephalogram (EEG) examination during steady-state stimuli when performing a stop-signal task. Then, we calculated the amplitude and phase of the steady-state responses in both visual and auditory modalities...

Primary hemifacial spasm is a hyperactive cranial nerve syndrome. The cause is always a neurovascular compression, generally at the root exit zone from the brainstem. Its curative treatment is microvascular compression, that may be performed as a first option, or secondarily when botulinum toxin injections fail.

Oppositional defiant disorder (ODD) is frequently associated with Attention Deficit Hyperactivity Disorder (ADHD) but no clear neurophysiological evidence exists that distinguishes the two groups. Our aim was to identify biomarkers that distinguish children with Attention Deficit Hyperactivity Disorder combined subtype (ADHD_C) from children with ADHD_C + ODD, by combining the results of quantitative EEG (qEEG) and the Junior Temperament Character Inventory (JTCI). 28 ADHD_C and 22 ADHD_C + ODD children who met the DSMV criteria participated in the study...

In children and adults with epilepsy, it is important to be aware of and diagnose common comorbidities that may have a large impact on quality of life. Comorbid neurodevelopmental disorders include intellectual disability, autism, and attention deficit hyperactivity disorder (ADHD). Depression and anxiety are common findings, and also the risk of psychosis is increased. The medication used to treat these comorbidities is found to be effective with little risks of seizure exacerbation, i.e. medication with methylphenidate, selective serotonin reuptake inhibitors (SSRIs) and second generation neuroleptics...

Despite a growing understanding that early adversity in childhood broadly affects risk for psychopathology, the contribution of stressful life events to the development of symptoms of attention-deficit/hyperactivity disorder (ADHD) is not clear. In the present study, we examined the association between number of stressful life events experienced and ADHD symptoms, assessed using the Attention Problems subscale of the Child Behavior Checklist, in a sample of 214 children (43% male) ages 9.11-13.98 years (M = 11...

Background and Objective: Understanding how trauma impacts the self-structure of individuals suffering from the Post-Traumatic Stress Disorder (PTSD) symptoms is a complex matter and despite several attempts to explain the relationship between trauma and the "Self", this issue still lacks clarity. Therefore, adopting a new theoretical perspective may help understand PTSD deeper and to shed light on the underlying psychophysiological mechanisms. Methods: In this study, we employed the "three-dimensional construct model of the experiential selfhood" where three major components of selfhood (phenomenal first-person agency, embodiment, and reflection/narration) are related to three Operational Modules (OMs) of the self-referential brain network...

PRC2 is a major regulator of gene expression in eukaryotes. It catalyzes the repressive chromatin mark H3K27me3, which leads to very low expression of target genes. NRT2.1, which encodes a key root nitrate transporter in Arabidopsis, is targeted by H3K27me3, but the function of PRC2 on NRT2.1 remains unclear. Here, we demonstrate that PRC2 directly targets and down-regulates NRT2.1, but in a context of very high transcription, in nutritional conditions where this gene is one of the most highly expressed genes in the transcriptome...
