Dihydromyricetin and Salvianolic acid B inhibit alpha-synuclein aggregation and enhance chaperone-mediated autophagy

Background: Progressive accumulation of α-synuclein is a key step in the pathological development of Parkinson's disease. Impaired protein degradation and increased levels of α-synuclein may trigger a pathological aggregation in vitro and in vivo. The chaperone-mediated autophagy (CMA) pathway is involved in the intracellular degradation processes of α-synuclein. Dysfunction of the CMA pathway imp

Novel oligodendroglial alpha synuclein viral vector models of multiple system atrophy : studies in rodents and nonhuman primates

Multiple system atrophy (MSA) is a horrible and unrelenting neurodegenerative disorder with an uncertain etiology and pathophysiology. MSA is a unique proteinopathy in which alpha-synuclein (α-syn) accumulates preferentially in oligodendroglia rather than neurons. Glial cytoplasmic inclusions (GCIs) of α-syn are thought to elicit changes in oligodendrocyte function, such as reduced neurotrophic su

The ECHR and contractual provisions on dispute resolution

The right of access to court and the right to a fair trial are fundamental rights guaranteed in all democratic states. The basic ideas are that anyone is entitled to have a dispute heard by a court of law in a procedure that meets certain requirements, i.e., a fair trial, and that the State has a duty to make such judicial dispute-resolution procedures possible. One of the most fundamental legal p

Measurement of charm and bottom production from semileptonic hadron decays in p+p collisions at s =200 GeV

Measurements of the differential production of electrons from open-heavy-flavor hadrons with charm- and bottom-quark content in p+p collisions at s=200 GeV are presented. The measurements proceed through displaced-vertex analyses of electron tracks from the semileptonic decay of charm and bottom hadrons using the PHENIX silicon-vertex detector. The relative contribution of electrons from bottom de

Search for Higgs boson pair production in the WW(*)WW(*) decay channel using ATLAS data recorded at √s = 13 TeV

A search for a pair of neutral, scalar bosons with each decaying into two W bosons is presented using 36.1 fb−1 of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider. This search uses three production models: non-resonant and resonant Higgs boson pair production and resonant production of a pair of heavy scalar particles.

Effects of delayed cord clamping on neurodevelopment and infection at four months of age : A randomised trial

Aim To investigate the effect that delayed and early umbilical cord clamping have on neurodevelopment, immunoglobulin G (IgG) and symptoms of infection during the first 4 months of life. Methods Full-term infants (n = 382) were randomised to delayed (≥180 sec) or early cord clamping (≤10 sec). The Ages and Stages Questionnaire (ASQ) was used to assess neurodevelopment at 4 months. Immunoglobulin G

PVL-positiva Staph aureus gav nekrotiserande pneumoni : Beskrivning av tre svära fall hos tidigare friska unga

We describe three cases of community-acquired pneumonia, in which the causative agent was methicillin sensitive S. Aureus positive for Panton-Valentine leukocidin (PVL). The patients were previously healthy children (2 weeks, 12 years and 15 years old). No epidemiologic connection existed, confirmed by spa-typing. Two cases were primary pneumonias with signs of necrosis, and the third case was a p

Monitoring of railway track with light high efficiency systems

Rail Track performance is highly dependent upon the magnitude and variation of differential track geometry. Consequently, there is an increasing interest in obtaining a consistent measure of trackbed stiffness and track geometry in the physical and time restrictions applicable on live track for assessing potential maintenance requirement and subsequent design of remedial measures. Furthermore, a l

Dread and Risk Elimination Premium for the Value of a Statistical Life

The value of a statistical life (VSL) is a widely used measure for the value of mortality risk reduction. As VSL should reflect preferences and attitudes to risk, there are reasons to believe that it varies depending on the type of risk involved. It has been argued that cancer should be considered a "dread disease," which supports the use of a "cancer premium." The objective of this study is to in

DMAC: Deadline-Miss-Aware Control

The real-time implementation of periodic controllers requires solving a co-design problem, in which the choice of the controller sampling period is a crucial element. Classic design techniques limit the period exploration to safe values, that guarantee the correct execution of the controller alongside the remaining real-time load, i.e., ensuring that the controller worst-case response time does no

Family caregiving in dementia : Prediction of caregiver burden 12 months after relocation to group-living care

The strain of caregiving associated with the care of demented persons living at home often continues after relocation, and group-living-care units (GL), designed for a small number of subjects, have been developed. The aim was to prospectively describe caregiver burden in relationship to symptoms of patients with dementia after relocation to GL. Sixty-four caregivers and 64 demented patients were

Sensitivity of interglacial Greenland temperature and δ 18O : Ice core data, orbital and increased CO 2 climate simulations

The sensitivity of interglacial Greenland temperature to orbital and CO 2 forcing is investigated using the NorthGRIP ice core data and coupled ocean-atmosphere IPSL-CM4 model simulations. These simulations were conducted in response to different interglacial orbital configurations, and to increased CO 2 concentrations. These different forcings cause very distinct simulated seasonal and latitudina

Modelling the regional climate and isotopic composition of Svalbard precipitation using REMOiso : A comparison with available GNIP and ice core data

Simulations of a regional (approx. 50 km resolution) circulation model REMOiso with embedded stable water isotope module covering the period 1958-2001 are compared with the two instrumental climate and four isotope series (δ18O) from western Svalbard. We examine the data from ice cores drilled on Svalbard ice caps in 1997 (Lomonosovfonna, 1250 m asl) and 2005 (Holtedahlfonna, 1150 m asl) and the G

Rapid environmental responses to climate-induced hydrographic changes in the Baltic Sea entrance

The Öresund (the Sound), which is a part of the Danish straits, is linking the marine North Sea and the brackish Baltic Sea. It is a transition zone where ecosystems are subjected to large gradients in terms of salinity, temperature, carbonate chemistry, and dissolved oxygen concentration. In addition to the highly variable environmental conditions, the area is responding to anthropogenic disturba

A cappella : Tjugofem körledares röster

I samband med tillkomsten av Körcentrum Syd 2007 gjordes en satsning på körforskning, bland annat ett forskningsprojekt där körledare intervjuades. Syftet var att undersöka och kartlägga praktiserande musikers syn på och behov av forskning och utvecklingsarbete. Resultaten har presenterats vid flera seminarier och i denna bok publiceras Karin Johanssons texter, som ett resultat av de genomförda in

Cost assessment of a production system - A method targeting a products aggregated value stream costs

A production system is often complex, involving several production steps with a material flow entering and exiting at different stages throughout the value stream. This article aims to present a method giving the aggregated cost of a product in a production system, were material and components entering the value stream carrying their own capital and handling costs. The article describes an empiric
