Endogenous and treatment-induced neuroplasticity in mouse models of Parkinson's disease
Parkinsons sjukdom (PD) är den näst vanligast förekommande åldersrelaterade neurodegenerativa sjukdomen efter Alzheimers. De främsta symptomen på PD är typiska rörelsesvårigheter, vilka beror på förlust av dopamin i hjärnregionen striatum. Ett annat viktigt särdrag är ansamlingar av proteinet alpha-synuclein i många nervceller inom flera hjärnområden. Den effektivaste behandlingen mot Parkinson-syParkinson´s disease (PD) is an age-related neurodegenerative disorder characterized by a loss of nigral dopamine (DA) neurons that project their axons to the striatum. Striatal DA depletion causes the typical motor symptoms of PD. Another key feature of PD are intracellular protein inclusions containing alpha-synuclein within affected brain regions. L-DOPA is the most effective treatment for the s
Temperature imaging in low-pressure flames using diode laser two-line atomic fluorescence employing a novel indium seeding technique
The use of diode lasers for spatially resolved temperature imaging is demonstrated in low-pressure premixed methane–air flames using two-line atomic fluorescence of seeded indium atoms. This work features the advantages of using compact diode lasers as the excitation sources with the benefits of two-dimensional planar imaging, which is normally only performed with high-power pulsed lasers. A versa
Manipulation of the spatial distribution of laser-accelerated proton beams by varying the laser intensity distribution
We report on a study of the spatial profile of proton beams produced through target normal sheath acceleration using flat target foils and changing the laser intensity distribution on the target front surface. This is done by either defocusing a single laser pulse or by using a split-pulse setup and irradiating the target with two identical laser pulses with variable spatial separation. The result

Inhibition of phosphodiesterase 3, 4, and 5 induces endolymphatic hydrops in mouse inner ear, as evaluated with repeated 9.4T MRI
Conclusion: The data indicate important roles for phosphodiesterase (PDE) 3, 4, 5, and related cAMP and cGMP pools in the regulation of inner ear fluid homeostasis. Thus, dysfunction of these enzymes might contribute to pathologies of the inner ear. Objective: The mechanisms underlying endolymphatic hydrops, a hallmark of inner ear dysfunction, are not known in detail; however, altered balance in
5-HT2B receptor antagonists attenuate myofibroblast differentiation and subsequent fibrotic responses in vitro and in vivo
Pulmonary fibrosis is characterized by excessive accumulation of connective tissue, along with activated extracellular matrix (ECM)-producing cells, myofibroblasts. The pathological mechanisms are not well known, however serotonin (5-HT) and 5-HT class 2 (5-HT2) receptors have been associated with fibrosis. The aim of the present study was to investigate the role of 5-HT2B receptors in fibrosis, u
Natural and anthropogenic influences on the population structure of white-tailed eagles in the Carpathian Basin and central Europe
European populations of the white-tailed eagle Haliaeetus albicilla suffered a drastic decline during the 20th century. In many countries, only a few dozen breeding pairs survived or the species disappeared completely. By today, the populations have recovered, naturally or through restocking (e.g. in Scotland or the Czech Republic). In the Carpathian Basin, which is now a stronghold in southern Eu
Comorbidities in patients with antineutrophil cytoplasmic antibody-associated vasculitis versus the general population
Objective. To evaluate the consultation rates of selected comorbidities in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV) compared with the general population in southern Sweden. Methods. We used data from a population-based cohort of patients with AAV diagnosed between 1998 and 2010 in Southern Sweden (701,000 inhabitants). For each patient we identified 4 reference
Comparative Emulsifying Properties of Octenyl Succinic Anhydride (OSA)-Modified Starch: Granular Form vs Dissolved State
The emulsifying ability of OSA-modified and native starch in the granular form, in the dissolved state and a combination of both was compared. This study aims to understand mixed systems of particles and dissolved starch with respect to what species dominates at droplet interfaces and how stability is affected by addition of one of the species to already formed emulsions. It was possible to create
New U–Pb geochronologic and palaeomagnetic constraints on the late Palaeoproterozoic Hartley magmatic event : evidence for a potential large igneous province in the Kaapvaal Craton during Kalahari assembly, South Africa
The volcanic Hartley Formation (part of the Olifantshoek Supergroup, which is dominated by red bed successions) in South Africa recorded depositional and tectonic conditions along the western Kaapvaal Craton during the late Palaeoproterozoic. It formed in association with red bed deposition elsewhere in the cratonic hinterland and along the craton’s northern margin. However, the exact correlation
Systematic study of bubble nuclei in relativistic mean field model
We have theoretically studied potential bubble nuclei (20,22O, 34,36Si, and 46Ar), which are experimentally accessible and have attracted several studies in the recent past. Relativistic mean field is employed in conjunction with the NL–SH parameter set. Our results show that among the possible candidates, 22Oand 34Si may be the most prominent candidates, showing significant depletion of density a
What socioeconomic factors are associated with different levels of antenatal care visits in Bangladesh? A behavioral model
We identify the socioeconomic determinants of three levels of antenatal care (ANC) visits (no, intermediate [1–3], and recommended [≥4]) in Bangladesh using a behavior model framework for health care utilization. Using multinomial logistic regression, we found that different levels of visits had different determinants; for example, media exposure increased the likelihood of intermediate compared w
Supporting Scope Tracking and Visualization for Very Large-Scale Requirements Engineering-Utilizing FSC+, Decision Patterns, and Atomic Decision Visualizations
Deciding the optimal project scope that fulfills the needs of the most important stakeholders is challenging due to a plethora of aspects that may impact decisions. Large companies that operate in rapidly changing environments experience frequently changing customer needs which force decision makers to continuously adjust the scope of their projects. Change intensity is further fueled by fierce ma
Distributions of spatial wave size for random fields
A method of measuring three-dimensional spatialwave size is proposed and statistical distributions of the size characteristics are derived in explicit integral forms for Gaussian sea surfaces. New definitions of wave characteristics such as the crest-height, the length, the size and the wave front location are provided in fully dimensional context. The joint statistical distributions of these wave
Safe drinking water in a changing environment : Membrane filtration in a Swedish context
Surface water is vital for Swedish drinking water supply. In the past decades, a trend of increased total organic carbon (TOC) concentrations has led to higher consumption of coagulants in drinking water treatment, and has pushed the levels in the outgoing water closer to the allowed levels of TOC. Also, two occasions of cryptosporidium outbreaks in northern Sweden have stressed the importance of
Applicability of Clinical Trials in an Unselected Cohort of Patients With Intracerebral Hemorrhage
BACKGROUND AND PURPOSE—: Patient selection in clinical trials on intracerebral hemorrhage (ICH) affects overall applicability of results. We estimated eligibility for completed, ongoing, and planned clinical trials in an unselected cohort of patients with ICH. METHODS—: Large clinical ICH trials were identified using trial registration databases. Each trial’s inclusion criteria were applied to a c

Solidarity in European asylum policies: response to a problem or part of it?
This intervention briefly goes through two schemes that allocate asylum-related responsibilities between states: the Dublin mechanism within the EU and the EU-Turkey statement. By identifying their flaws, the paper suggests that although solidarity has been invoked as a response to the so-called “refugee crisis”, the way it has been conceptualised makes it part of the problem.
