Chondrocytes derived from mesenchymal stromal cells and induced pluripotent cells of patients with familial osteochondritis dissecans exhibit an endoplasmic reticulum stress response and defective matrix assembly

Familial osteochondritis dissecans (FOCD) is an inherited skeletal defect characterized by the development of large cartilage lesions in multiple joints, short stature, and early onset of severe osteoarthritis. It is associated with a heterozygous mutation in the ACAN gene, resulting in a Val-Met replacement in the C-type lectin domain of aggrecan. To understand the cellular pathogenesis of this c

The LHCb Muon Control System the DAQ domain

The LHCb Muon System consists of 122000 front-end channels, distributed on about 8000 front-end boards (on detector). 152 Off detector boards (each containing 192 channels) gather information from front-end and send it to the DAQ and trigger systems. The Muon System is highly configurable and is conceived to allow a deep control of the behavior of the whole system during data taking. This results

ELMB microcontroller firmware and scada integration for the LHCb muon detector readout control system

The LHCb system requires high efficiency muon detection into LHC bunch crossing: 95% into a 25 ns time window. To reach such efficiency many parameters of the detector readout apparatus have to be calibrated and adjusted and its channels must be aligned in time. In addition, essential characteristics must be monitored to guarantee a good working condition of the apparatus (to avoid loss of efficie

The muon front-end control electronics of the LHCb experiment

The LHCb muon readout apparatus is made of 1368 Multi-Wire Proportional Chambers (MWPC) and 24 Gas Electron Multiplier (GEM) chambers connected to 7632 16-channel front-end boards, resulting in 122.112 channels to be read out. After a pp collision, all the resulting signals must be read within 25 ns, before the next collision. The large-scale of the system and the time constrains naturally led to

Neutron Irradiation Techniques

In late 2016, Lund is on the verge of becoming the center of accelerator-based material science in Europe.The MAX IV Laboratory, an electron synchrotron, was inaugurated in June 2016 with a scientific program to commence shortly and the European Spallation Source ERIC (ESS), a spallation neutron source, is presently under construction and anticipated to be fully operational by 2022.These facilitieThe He-3 “crisis” has become a fact in the last decade and large scale neutron detectors based on He-3 technologies have become unaffordable. This new He-3 reality has resulted in a major effort worldwide to develop replacement neutron-detector technologies. Many of these technologies are in their infancy and need to be thoroughly tested before becoming mainstream, while others are approaching com

Brain bioavailability of human intravenous immunoglobulin and its transport through the murine blood-brain barrier

Intravenous immunoglobulin (IVIg) is currently evaluated in clinical trials for the treatment of various disorders of the central nervous system. To assess its capacity to reach central therapeutic targets, the brain bioavailability of IVIg must be determined. We thus quantified the passage of IVIg through the blood-brain barrier (BBB) of C57Bl/6 mice using complementary quantitative and qualitati

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

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

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

Biophysical and Human Controls of Land Productivity under Global Change : Development and Demonstration of Parsimonious Modelling Techniques

Nettoprimärproduktionen (NPP), är källan till den mat vi äter, virket vi bygger hus av och veden vi eldar med. NPP spelar också en stor roll i den globala kolcykeln, genom fotosyntesen så binder växterna koldioxid från luften och producerar blad och stammar. Hur mycket växterna producerar styrs till stor utsträckning av klimatet samt hur mycket koldioxid som finns i atmosfären. Detta gör att de föNet primary production (NPP) serves as an indicator for plant-based resources such as food, timber and biofuel for human appropriation. It is defined by the annual production of plant matter and is mainly controlled by climate and human activities. Climate change in combination with human activities is altering NPP. As the controls of NPP are expected to further change in the future, it is vital t
