The increase in Ca(2+)-activated force caused by polyamines in beta-escin-permeabilized guinda pig ileum is shown to be associated with increased myosin 20-kDa light chain (LC20) phosphorylation and shortening velocity. Myosin LC20 dephosphorylation with arrested kinase activity was slower in the presence of 1 mM spermine. Smooth muscle phosphatases (SMP-I, -II, -III, and -IV) isolated from turkey
The theme of this thesis is to study discretizations of nonlinear dissipative evolution equations, which arise in e.g. advection-diffusion-reaction processes. The convergence analysis is conducted by first considering an abstract time discretization of the problem, which enables a decoupling of the time and spatial approximations, and secondly by introducing the spatial discretization as an evolut
Chipped tobacco stalks were subjected to steam pretreatment at 205 degreesC for either 5 or 10 min before enzymatic hydrolysis. Glucose (15.4 - 17.1 g/l) and xylose (4.5-5.0 g/l) were the most abundant monosaccharides in the hydrolysates. Mannose, galactose and arabinose were also detected. The hydrolysate produced by pretreatment for 10 min contained higher levels of all sugars than the 5 min-pre
Surgical procedures in hemophiliacs is a demanding challenge for the surgeon and hematologist. This report deals with a successful laparoscopic cholecystectomy in a young patient with hemophilia B. Despite a prolonged operation time, because of a partially intrahepatic gallbladder, no bleeding complications were registered and the patient recovered well. Laparoscopic cholecystectomy seems to be th
A gas chromatographic-ion trap tandem mass spectrometric method was developed for the quantification of muramic acid, a marker of bacterial peptidoglycan, in environmental and clinical specimens. Samples (bacteria, house dust and urine) were heated in methanolic hydrochloric acid overnight and extracted with hexane for removal of hydrophobic compounds. The aqueous phase was evaporated and heated i
Measurement of bone mineral concentration (BMC) can be done by several modalities. Quantitative computed tomography (QCT) can be used for measurements at different sites and with different types of bone (trabecular-cortical). This study presents a modified method reducing the influence of fat. Determination of BMC was made from measurements with single-energy computed tomography (CT) of the mean H
Context: Insulin-stimulated glucose uptake in skeletal muscle is mediated through translocation of the insulin-sensitive glucose transporter 4 ( GLUT4)-containing vesicles to the plasma membrane. Thus, skeletal muscle GLUT4 content plays an important role in whole-body insulin sensitivity. Objectives: The objectives of this study were 1) to examine the relative impact of genetic vs. environmental
We review the present status of the hadronic light-by-light contribution to muon g - 2 and critically compare recent calculations.
In this paper, the results of different multiple window spectrum analysis methods are compared in the estimation of heart rate variability (HRV) power spectra, in the high frequency band (HF), around 0.25 Hz, related to respiratory sinus arrhythmia (RSA). The evaluation is performed by simulating different spectrum shapes and peak frequency locations and calculating the mean squared error of a fre
Texture of potatoes with different shapes (slices and strips) were evaluated after frying and in some cases after baking. Blanched and unblanched potato slices (Bintje variety) were fried at four oil temperatures: 160, 170, 180 and 190C until reaching a moisture content of similar to1.7%. A puncture test with three point support for the slices was applied to measure the texture of potato chips usi
Popular Abstract in Swedish Vad händer i samspelet mellan vårdbiträden i hemtjänsten och äldre människor de hjälper? Hur förhåller man sig till varandras förväntningar på relationen? Vilken inverkan har den äldres familj och vårdbiträdets arbetsgrupp på den äldres och vårdbiträdets relation? Detta är centrala frågor i denna avhandling, som handlar om omsorgssituationen i hemtjänsttagarens hem utiThis dissertation examines the interaction between municipal home-helpers and care re-cipients from a social psychological perspective. One of the starting points is a critique of some classical works in the caring science inspired by women’s studies for not taking into consideration that care-giving work constitutes social interaction. The aim is to analyse how elderly people and the home-helpers
Chloroplast thylakoid protein phosphorylation was discovered, and the most conspicuous phosphoproteins identified, by John Bennett at Warwick University. His initial findings were published in 1977. The phosphoproteins included apoproteins of chloroplast light harvesting complex II. Thylakoid protein phosphorylation was shown to influence distribution of excitation energy between Photosystems I an
Aim. The aim of this study was to illuminate patients' lived experience during magnetic resonance imaging. Background. Magnetic resonance imaging has increased in importance since the early 1980s and is today a common useful diagnostic tool. Although magnetic resonance imaging are non-invasive and considered painless, many patients experience anxiety, sometimes so strong that the scan has to be t
