Fate-Mapping of GM-CSF Expression Identifies a Discrete Subset of Inflammation-Driving T Helper Cells Regulated by Cytokines IL-23 and IL-1β.
2019
Summary Pathogenic lymphocytes initiate the development of chronic inflammatory diseases. The cytokine granulocyte-macrophage colony-stimulating factor (GM-CSF) (encoded by Csf2) is a key communicator between pathogenic lymphocytes and tissue-invading inflammatory phagocytes. However, the molecular properties of GM-CSF-producing cells and the mode of Csf2 regulation in vivo remain unclear. To systematically study and manipulate GM-CSF+ cells and their progeny in vivo, we generated a fate-map and reporter of GM-CSF expression mouse strain (FROG). We mapped the phenotypic and functional profile of auto-aggressive T helper (Th) cells during neuroinflammation and identified the signature and pa…
Women reduced the sex difference in open-water ultra-distance swimming - La Traversee Internationale du Lac St-Jean, 1955-2012
2014
In La Traversée Internationale du Lac St-Jean, held between 1955 and 2012 in Canada, the fastest women (r2 = 0.61, p < 0.0001) and men (r2 = 0.66, p < 0.0001) improved swimming speed over the years but the sex difference remained unchanged at 8.8% ± 5.6% (r2 = 0.069, p = 0.065). Annually, for the 3 fastest swimmers, both women (r2 = 0.53, p < 0.0001) and men (r2 = 0.71, p < 0.0001) improved swimming speed between 1973 and 2012 and the sex difference decreased (r2 = 0.29, p = 0.0016) from 14.4% ± 11.0% (1973) to 3.7% ± 1.4% (2012).
Cognitive mechanisms underlying reading and spelling development in five European orthographies
2014
This paper addresses the question whether the cognitive underpinnings of reading and spelling are universal or language/orthography-specific. We analyzed concurrent predictions of phonological processing (awareness and memory) and rapid automatized naming (RAN) for literacy development in a
Neurochemical alterations in women with borderline personality disorder and comorbid attention-deficit hyperactivity disorder
2010
Borderline personality disorder (BPD) is associated with structural and functional brain changes. Recent models and findings refer to alterations of glutamate and total N-acetylaspartate (tNAA) in this condition.Absolute quantities of tNAA, creatine, glutamate, glutamine, myoinositol and total choline were measured using 3 Tesla magnetic resonance spectroscopy of the left anterior cingulate cortex and the left cerebellum in 14 unmedicated women with BPD and comorbid attention-deficit hyperactivity disorder (ADHD) and 18 healthy women. Both groups were matched with respect to age, education and premorbid intelligence.In the anterior cingulate, we found significantly higher tNAA and glutamate…
Reduced interhemispheric structural connectivity between anterior cingulate cortices in borderline personality disorder
2008
Functional and structural alterations of the anterior cingulate cortex (ACC), a key region for emotional and cognitive processing, are associated with borderline personality disorder (BPD). However, the interhemispheric structural connectivity between the left and right ACC and between other prefrontal regions in this condition is unknown. We acquired diffusion-tensor imaging data from 20 healthy women and 19 women with BPD and comorbid attention-deficit hyperactivity disorder (ADHD). Interhemispheric structural connectivity between both sides of the ACC, dorsolateral prefrontal cortices and medial orbitofrontal cortices was assessed by a novel probabilistic diffusion tensor-based fiber tra…
Depression during an acute episode of schizophrenia or schizophreniform disorder and its impact on treatment response
2008
The aim of the present study was to examine the relevance of depressive symptoms during an acute schizophrenic episode for the prediction of treatment response. Two hundred inpatients who fulfilled DSM-IV criteria for schizophrenia or schizophreniform disorders were assessed at hospital admission and after 6 weeks of inpatient treatment using the Positive and Negative Syndrome Scale (PANSS) and the Hamilton Rating Scale for Depression (HAM-D). Depressive symptoms showed positive correlations with both positive and negative symptoms at admission and after 6 weeks, and decreased during 6 weeks of treatment. Pronounced depressive symptoms (HAM-D score> or =16) were found in 28% of the sample a…
Genetic analysis of dyslexia candidate genes in the European cross-linguistic NeuroDys cohort
2013
The work conducted at the WTCHG was supported by Wellcome Trust grants [076566/Z/05/Z] and [075491/Z/04]; the work in Zurich partly by an SNSF grant [32-108130]. We also thank MAF (Mutation Analysis core Facility) at the Karolinska Institute, Novum, Huddinge. The French part of the project was funded by Agence Nationale de la Recherche (ANR-06-NEURO-019-01 GENEDYS) and Ville de Paris. S Paracchini is a Royal Society University Research Fellow. D Czamara was supported by the Deutsche Forschungsgemeinschaft (German Research Foundation) within the framework of the Munich Cluster for Systems Neurology (EXC 1010 SyNergy). Dyslexia is one of the most common childhood disorders with a prevalence o…
Preventing problematic internet use during the COVID-19 pandemic: Consensus guidance
2020
As a response to the COVID-19 pandemic, many governments have introduced steps such as spatial distancing and “staying at home” to curb its spread and impact. The fear resulting from the disease, the ‘lockdown’ situation, high levels of uncertainty regarding the future, and financial insecurity raise the level of stress, anxiety, and depression experienced by people all around the world. Psychoactive substances and other reinforcing behaviors (e.g., gambling, video gaming, watching pornography) are often used to reduce stress and anxiety and/or to alleviate depressed mood. The tendency to use such substances and engage in such behaviors in an excessive manner as putative coping strategies i…
An electrophysiological study of print processing in kindergarten: the contribution of the visual n1 as a predictor of reading outcome.
2013
Sensitivity to print is characterized by a left occipito-temporal negativity to words in the event-related potential N1. This sensitivity is modulated by reading skills and may thus represent a neural marker of reading competence. Here we studied the development of the N1 in regular and poor readers from preschool age to school age to test whether the amplitude of the N1 predicts children's reading outcomes. Our results suggest a predictive value of the print-sensitive negativity over the right hemisphere. Whether this N1 may serve as a biomarker to improve prognosis in preliterate children should be clarified in future studies.
Association of prestroke metformin use, stroke severity, and thrombolysis outcome
2020
ObjectiveTo evaluate whether pretreatment with metformin (MET) is associated with less stroke severity and better outcome after IV thrombolysis (IVT), we analyzed a cohort of 1,919 patients with stroke with type 2 diabetes mellitus in a multicenter exploratory analysis.MethodsData from patients with diabetes and ischemic stroke treated with IVT were collected within the European Thrombolysis in Ischemic Stroke Patients (TRISP) collaboration. We applied propensity score matching (PSM) to obtain balanced baseline characteristics of patients treated with and without MET.ResultsOf 1,919 patients with stroke with type 2 diabetes who underwent IVT, 757 (39%) had received MET before stroke (MET+),…
