Parkinson's Disease in a Dish : What Patient Specific-Reprogrammed Somatic Cells Can Tell Us about Parkinson's Disease, If Anything?

Technologies allowing for the derivation of patient-specific neurons from somatic cells are emerging as powerful in vitro tools to investigate the intrinsic cellular pathological behaviours of the diseases that affect these patients. While the use of patient-derived neurons to model Parkinson's disease (PD) has only just begun, these approaches have allowed us to begin investigating disease pathog

Impact of intravenous immunoglobulin on the dopaminergic system and immune response in the acute MPTP mouse model of Parkinson's disease

Intravenous immunoglobulin (IVIg) is a blood-derived product, used for the treatment of immunodeficiency and autoimmune diseases. Since a range of immunotherapies have recently been proposed as a therapeutic strategy for Parkinson's disease (PD), we investigated the effects of an IVIg treatment in a neurotoxin-induced animal model of PD. Mice received four injections of MPTP (15 mg/kg) at 2-hour i

Inflammation and neurodegeneration : the story 'retolled'

Toll-like receptors (TLRs) play a crucial role in innate immunity by recognizing conserved motifs predominantly found in microorganisms. Increasing evidence supports a role for TLRs in sterile inflammation as observed in neurodegenerative disorders. This includes work suggesting a contribution for these receptors to the pathophysiology of Alzheimer's disease (AD), Parkinson's disease (PD), and rel

MyD88 deficiency results in both cognitive and motor impairments in mice

The myeloid differentiation primary response gene 88 (MyD88) product is the most common adaptor protein implicated in Toll-like and interleukin receptor (TIR) domain signaling and thus plays an important role in the innate immune system. Despite the fact that the MyD88-dependent pathway has emerged as an important player in cell death processes described in several animal models of neurodegenerati

The role of the MYD88-dependent pathway in MPTP-induced brain dopaminergic degeneration

BACKGROUND: Mounting evidence supports a significant role of inflammation in Parkinson's disease (PD) pathophysiology, with several inflammatory pathways being suggested as playing a role in the dopaminergic degeneration seen in humans and animal models of the disease. These include tumor necrosis factor, prostaglandins and oxidative-related stress components. However, the role of innate immunity

The critical role of the MyD88-dependent pathway in non-CNS MPTP-mediated toxicity

A growing body of evidence supports a role of inflammation in the loss of central nervous system neurons both to acute and chronic insults, while its contribution to the loss of neurons in the enteric nervous system remains largely uninvestigated. We have addressed this issue by exploring the role of inflammation in dopaminergic (DAergic) myenteric neuronal degeneration secondary to MPTP lesioning

Neuroinflammation is associated with changes in glial mGluR5 expression and the development of neonatal excitotoxic lesions

It has been hypothesized that neuroinflammation triggered during brain development can alter brain functions later in life. We investigated the contribution of inflammation to the alteration of normal brain circuitries in the context of neuroexcitotoxicity following neonatal ventral hippocampal lesions in rats with ibotenic acid, an NMDA glutamate receptor agonist. Excitotoxic ibotenic acid lesion

Environmental toxins and Parkinson's disease : what have we learned from pesticide-induced animal models?

Parkinson's disease (PD) is a common neurodegenerative disorder largely of idiopathic nature with the exceptions of rare familial forms, and is characterized by both motor and non-motor disturbances. Pathologically, most motor features are the result of a dramatic loss of ventral tier mesencephalic dopaminergic neurons and thus dopamine content at their target sites. Although the exact etiology of

Automatic Creation of Multilingual Semantic Networks from Wikipedia

This paper describes the automatic creation of semantic networks from Wikipedia. Following Lipczak et al. (2014), we constructed the graphs corresponding to the semantic networks by merging across languages the categories manually assigned by the users. This results in a network of related concepts for each entity of Wikipedia. We used these networks as a component of an entity linking system. the

Challenges from Integrating Usability Activities in Scrum : Why is Scrum So Fashionable?

Scrum is currently a widely used process in most areas of software development. Conversely, usability activities as prescribed in the area of HCI are not widely used in the software industry, especially not in agile software development projects. Through an analysis of interview and survey data from five studies we scrutinize the reasons for choosing Scrum, consequences of using Scrum, and study tScrum is currently a widely used process in most areas of software development.

Professionernas farhågor om införandet av eJournal inom vuxenpsykiatrin i Region Skåne

Hösten 2015 var Region Skåne först i Sverige med att lägga till patientjournaler från psykiatrin till invånartjänsten eJournal. Genom tjänsten, har alla patienter i den vuxenpsykiatriska vården i Region Skåne tillgång till sin journal via nätet. Det finns lite kunskap om hur professioner na inom den psykiatriska vården förväntar sig att deras arbete kommer att påverkas av den ökade transparens som

Can Women Have Children and a Career: IV Evidence from IVF Treatments

This paper introduces a new IV strategy based on IVF (in vitro fertilization) induced fertility variation among childless women to estimate the causal effect of having children on their career. For this purpose, we use administrative data on IVF treated women in Denmark. Because observed chances of IVF success do not depend on labor market histories, IVF treatment success provides a plausible inst

Employees’ work environment and patients’ rights, conflicting responsibilities when implementing patient online access to their EHR

This paper is based on an interview study examining the implementation of the eHealth service patient online access to electronic health records in two county councils in Sweden. Our aim is to present and discuss the two councils’ implementation processes and the differences between them, with particular focus on the implementers’ consideration of caregivers’ work environment. A theoretical aim is

Hur tvärprofessionellt arbete kan leda till förflyttning av läkares lojalitet

Data från en empirinära studie av tvärprofessionellt teamarbete på en intensivvårdsavdelning (IVA) visade att läkarnas huvudsakliga lojalitet flyttats från den egna professionen till teamen och avdelningen. Data insamlades med djupintervjuer, observationer och samtalsgrupper. I papret kommer vi att beskriva den bakomliggande förändringsprocess som genomförts på avdelningen. I förändringsprocessen

Gender differences in autism spectrum disorders: Divergence among specific core symptoms

Community-based studies have consistently shown a sex ratio heavily skewed towards males in autism spectrum disorders (ASD). The factors underlying this predominance of males are largely unknown, but the way girls score on standardized categorical diagnostic tools might account for the underrecognition of ASD in girls. Despite the existence of different norms for boys and girls with ASD on several
