Urine D-arabinitol/L-arabinitol ratio in diagnosis of invasive candidiasis in newborn infants

Infants treated in neonatal intensive care units suffer an increased risk for invasive candidiasis, but the diagnosis is sometimes difficult. D-arabinitol is a metabolite of most pathogenic Candida species. An elevated urine D-arabinitol/L-arabinitol (DA/LA) ratio is a sensitive sign of invasive candidiasis in children with cancer, but the method has not been previously evaluated for newborn infan

Is aqueductal stroke volume, measured with cine phase-contrast magnetic resonance imaging scans useful in predicting outcome of shunt surgery in suspected normal pressure hydrocephalus?

OBJECTIVE: To evaluate clinical usefulness of cerebrospinal fluid stroke volume (SV) assessed in the cerebral aqueduct, via cine phase-contrast magnetic resonance imaging, for predicting outcome after shunt surgery in suspected normal pressure hydrocephalus. METHODS: Thirty-eight patients with suspected normal pressure hydrocephalus were included. SV was assessed using cine phase-contrast magnetic

STRENGTH TRAINING AFTER STROKE: EFFECTS ON MUSCLE FUNCTION, GAIT PERFORMANCE AND PERCEIVED PARTICIPATION

Popular Abstract in Swedish Det övergripande syftet med denna avhandling var att hos individer med kvarstående muskelsvaghet efter stroke utvärdera effekterna av progressiv styrketräning (PRT) av knäledens sträck- och böjmuskler på muskelstyrka och muskelspänning, men även att analysera om en förbättrad muskelstyrka påverkar gångförmåga och upplevd delaktighet (individens egen upplevelse av hur maThe overall aim of this thesis was to evaluate the effects of strength training on muscle function, gait performance and perceived participation in subjects with chronic mild to moderate post-stroke hemiparesis. A main impairment after stroke is reduced muscle strength. This post-stroke weakness is a major contributor to mobility limitations, which can prevent the resumption of activities of dail

Trellis Decoding: From Algorithm to Flexible Architectures

Trellis decoding is a popular method to recover encoded information corrupted during transmission over a noisy channel. Prominent members of this class of decoding algorithms are the Viterbi algorithm, which provides maximum likelihood estimates, and the BCJR algorithm, which is a maximum a posteriori estimator commonly used in iterative decoding. In this thesis, the Viterbi algorithm is chosen si

Endothelial-to-mesenchymal transition contributes to cardiac fibrosis

Cardiac fibrosis, associated with a decreased extent of microvasculature and with disruption of normal myocardial structures, results from excessive deposition of extracellular matrix, which is mediated by the recruitment of fibroblasts. The source of these fibroblasts is unclear and specific anti-fibrotic therapies are not currently available. Here we show that cardiac fibrosis is associated with

Värmeförluster till mark : grundläggning av typen platta på mark

I denna studie analyseras och anges metoder att beräkna värmeförlusterna mot mark. Värmeförlusterna erhålls med hjälp av formler, diagram och tabeller. Effekten av olika kantisoleringar, ändringar av ute- och innetemperaturer, köldknäppar, tjäle och snö beräknas samt värmeförluster vid ny byggnad under uppbyggnad av värmekudde.

Silurian Carbonate Platforms of Gotland, Sweden - Archives of Local, Regional and Global Environmental Changes

Popular Abstract in Swedish Denna doktorsavhandling syftar till att identifiera och tolka förändringar i den marina miljön, avspeglade i Gotlands siluriska berggrund. Silurperioden (ca 444-416 miljoner år sedan) har traditionellt beskrivits som ett tidsintervall med ett varmt växthusklimat och hög global havsnivå med små miljömässiga förändringar i den marina miljön. Under det senaste decenniet haThis thesis treats the Silurian carbonate platforms of Gotland, Sweden, which formed close to the equator within the East Baltic Basin. Three different time intervals, all involving changes in facies composition and structure of the platforms, have been studied; Late Homerian, latest Homerian ? earliest Gorstian, and late Ludfordian, respectively. Two of the intervals, the Late Homerian and the la

Perception of South Swedish Word Accents

A perceptual experiment concerning South Swedish word accents (accent I, accent II) is described. By means of editing and resynthesis techniques the F0 pattern of a test word in a phrase context has been systematically manipulated: initial rise (glide vs. jump) and final concatenation (6 timing degrees of the accentual fall). The results indicate that both a gliding rise and a late fall seem neces

Immunogenicity properties of authentic and heterologously synthesized structural protein VP2 of infectious pancreatic necrosis virus.

The sole coat protein VP2 of infectious pancreatic necrosis virus (IPNV) was isolated and purified from intact virions, propagated in CHSE-214 cells. Likewise was the full-length VP2 protein isolated and purified upon cloning and expression of the corresponding complete gene in E. coli. The two purified proteins of different synthetic origins carrying identical primary structures were utilized in

Transport and release of insulin granules during biphasic insulin secretion

Glucose-evoked insulin secretion exhibits two phases: The first phase represents exocytosis of insulin granules situated at the plasma membrane, whereas the second phase reflects insulin release from granules continuously recruited to the plasma membrane. This thesis investigates different aspects of phasic insulin secretion, with the specific aims to elucidate the possible contribution of insulin

DYNAMIC MODELLING OF BIOGEOCHEMICAL PROCESSES IN FOREST ECOSYSTEMS

Popular Abstract in Swedish Under de senaste decennierna har våra skogar utsatts för en allt högre grad av stress som en följd av förändrade produktionsmönster och en hög deposition av gödande och försurande ämnen, såsom kväve ovh svavel. Kväve är det ämne som begränsar trädens tillväxt, och det höga nedfallet av detta ämne har resulterat i att träden växt mycket snabbbare. Deras behov av andra näForests in Sweden are undergoing rapid and considerable changes regarding both management methods and environmental conditions. To understand the effects of these changes and to be able to predict impending changes in forest ecosystems, a holistic understanding of the processes governing the ecosystem is needed. To gain such an understanding, the ForSAFE model of the biogeochemical cycles in a for

A method to determine the dynamic load distribution in a chain drive

This paper presents a method to calculate the forces in a chain and, thus, the resulting load distribution along the sprockets in a chain transmission working at a moderate or high speed. When the chain drive is loaded, the rollers that contact the sprockets will move along the flanks to different height positions. There are mainly two different ways to determine the actual positions: to assume th
