Ceruloplasmin functional changes in Parkinson's disease-cerebrospinal fluid.

Ceruloplasmin, a ferroxidase present in cerebrospinal fluid (CSF), plays a role in iron homeostasis protecting tissues from oxidative damage. Its reduced enzymatic activity was reported in Parkinson's disease (PD) contributing to the pathological iron accumulation. We previously showed that ceruloplasmin is modified by oxidation in vivo, and, in addition, in vitro by deamidation of specific NGR-mo

Vestibular PREHAB and gentamicin before schwannoma surgery may improve long-term postural function

Background: Unilateral vestibular deafferentation (uVD), as performed in vestibular schwannoma surgery, results in a chronic vestibular deficit, though most of the insufficiency can be compensated by other sensory input. By vestibular training (prehabituation) performed before surgery, motor adaptation processes can be instigated before the actual lesion. The adaptation processes of the altered se

A Bayesian model for estimating observer translation and rotation from optic flow and extra-retinal input

We present a Bayesian ideal observer model that estimates observer translation and rotation from optic flow and an extra-retinal eye movement signal. The model assumes a rigid environment and noise in velocity measurements, and that eye movement provides a probabilistic cue for rotation. The model can simulate human heading perception across a range of conditions, including: translation with simul

Between Uncertainty and Certainty

In this study, 10 hematologists and 10 lung oncologists were interviewed regarding the information they provide to patients in four situations of uncertainty: determining the treatment that is in the patient's best interest; recurrence or progression of the patient's disease; determining when to withdraw life-prolonging treatment; discussing death, addressing questions such as whether the patient

A Class-D CMOS DCO with an on-chip LDO

This paper presents the co-design of a class-D digitally-controlled oscillator (DCO) and a low-dropout voltage regulator (LDO) generating the supply voltage for the DCO. Despite the high intrinsic supply pushing of the class-D oscillator topology, the LDO noise has only a very marginal impact on the DCO phase noise. The class-D DCO and LDO have been integrated in a 65nm CMOS process without any th

Ear Reconstruction. Clinical and physiological evaluations.

Popular Abstract in Swedish Mikroti är en medfödd avvikelse där ytterörat inte utvecklats normalt. Defekten kan variera från att örat nästan är normalt till att det saknas helt och hållet, s.k. anoti. I Sverige inträffar detta i c:a 2 fall per 100 000 nyfödda. Pojkar drabbas i större utsträckning och höger sida är den vanligaste. Båda sidor drabbas i c:a en tiondel av fallen. Förträngning av yttreMicrotia is a congenital malformation where the auricle is not fully developed. In some cases the malformation is complete and the auricle is absent. In Sweden the incidence of microtia is about 2 per 10,000 births. Reconstruction of the external ear is possible by using autologous rib cartilage in three surgical steps: rib cartilage transplantation, ear elevation and final adjustments. Although t

Measurement of the top quark-pair production cross section with ATLAS in pp collisions at root s=7 TeV

A measurement of the production cross-section for top quark pairs (t (t) over bar) in pp collisions at root s = 7 TeV is presented using data recorded with the ATLAS detector at the Large Hadron Collider. Events are selected in two different topologies: single lepton (electron e or muon mu) with large missing transverse energy and at least four jets, and dilepton (ee, mu mu or e mu) with large mis

Recent advances in 2D and 3D in vitro systems using primary hepatocytes, alternative hepatocyte sources and non-parenchymal liver cells and their use in investigating mechanisms of hepatotoxicity, cell signaling and ADME

This review encompasses the most important advances in liver functions and hepatotoxicity and analyzes which mechanisms can be studied in vitro. In a complex architecture of nested, zonated lobules, the liver consists of approximately 80 % hepatocytes and 20 % non-parenchymal cells, the latter being involved in a secondary phase that may dramatically aggravate the initial damage. Hepatotoxicity, a

Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV

The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of root s = 7 TeV corresponding to an integrated luminosity of 38 pb(-1). Jets are reconstructed with the anti-k(t) algorithm with distance parameters R = 0.4 or R = 0.6. Jet energy and angle corrections are determined fr

Non-linear behaviour of base-isolated building supported on flexible soil under damaging earthquakes

Seismic isolation is a strategy to reduce damage of structures exposed to devastating earthquake excitations. Isolation systems, applied at the base of buildings, lower the fundamental frequency of the structure below the range of dominant frequencies of the ground motion as well as allow to dissipate more energy during structural vibrations. The effectiveness of the base-isolated buildings in dam

Integration of signalling in smooth muscle caveolae

Caveolae and lipid rafts are plasma membrane microdomains that are considered to play a role in cellular signalling. Caveolins and cavins as well as cholesterol are required for the structure and function of caveolae. The papers summarized in this thesis examine the role of caveolae in smooth muscle function. Ca2+-sensitization is a contractile process depending on inhibition of myosin phosphatase

När Gunder Hägg blev ”Gunder Hägg” – anteckningar till en mediebiografi

This article focuses on the Swedish middle distance runner Gunder Hägg (1918–2004). The peak of his career coincided with WWII, and in the Summer of 1942 he broke 10 out of his 15 world records. The year after, he made a much appreciated and successful running tour to the US. This made Hägg the first real media sports star in Sweden. The article analyses the representation of Hägg in different med

The Swedish Version of the Ritvo Autism and Asperger Diagnostic Scale: Revised (RAADS-R). A Validation Study of a Rating Scale for Adults

There is a paucity of diagnostic instruments for adults with autism spectrum disorder (ASD). This study evaluates the psychometric properties of the Swedish version of the Ritvo Autism and Asperger Diagnostic Scale-Revised (RAADS-R), an 80-item self-rating scale designed to assist clinicians diagnosing ASD in adults. It was administered to 75 adults with ASD and 197 comparison cases. Also, a subse

Haemophilus influenzae interacts with the human complement inhibitor factor H

Pathogenic microbes acquire human complement inhibitors to circumvent the innate immune system. In this study, we identify two novel host-pathogen interactions, factor H (FH) and factor H-like protein 1 (FHL-1), the inhibitors of the alternative pathway that binds to Hib. A collection of clinical Haemophilus influenzae isolates was tested and the majority of encapsulated and unencapsulated bound F

Automatic pre-tessellation culling

Graphics processing units supporting tessellation of curved surfaces with displacement mapping exist today. Still, to our knowledge, culling only occurs after tessellation, that is, after the base primitives have been tessellated into triangles. We introduce an algorithm for automatically computing tight positional and normal bounds on the fly for a base primitive. These bounds are derived from an

A numerical model of nearshore waves, currents, and sediment transport

A two-dimensional numerical model of nearshore waves, currents, and sediment transport was developed. The multi-directional random wave transformation model formulated by Mase [Mase, H., 2001. Multidirectional random wave transformation model based on energy balance equation. Coastal Engineering Jounnal 43(4), 317-337.] based on an energy balance equation was employed with an improved description

Exploration of motorcyclists’ behavior at access points of a Malaysian primary road – A qualitative observation study

The majority of motorcycle accident fatalities in Malaysia occur on primary roads, especially at access points situated along straight road sections. To explore the behavioral factors that may contribute to motorcyclists being involved in hazardous situations at these locations and to develop working hypotheses for a consecutive quantitative study, a qualitative observational study was carried out
