Patients above sixty years of age with Hodgkin's lymphoma treated with a new strategy

In the Swedish National Care Programme for Hodgkin's lymphoma (HL) a less intensive chemotherapy regimen with individualized dosing (LVPP/OEPA) was introduced in 1989. In total, 139 patients, 77 between 1985 and 1988 and 62 between 1989 and 1992, were studied. Mean ages were 72 and 71 years, respectively. One hundred and nineteen patients were treated with curative intention, 63 (82%) between 1985

Post-industrial division of labour as a systemic barrier for immigrants in the Swedish labour market

ABSTRACT. Differences in labour force participation and unemployment rates between indigenous populations and immigrants are common throughout Europe. But the gap seems to be particularly wide in Sweden. Based on studies of work places that traditionally employed large numbers of immigrants, but where they are now declining, it is argued that a driving force behind this process of exclusion is to

Effect of tissue wounding on the results from calorimetric measurements of vegetable respiration

When plant tissue is wounded a number of protective processes start. We have made a study by isothermal calorimetry of the heat production response of root and tuber tissue to wounding. Samples with different surface to volume ratios were prepared from carrots, potatoes and swedes (rutabaga) and the thermal power was measured in closed glass ampoules in a TAM Air isothermal calorimeter. The evalua

Polyamines inhibit myosin phosphatase and increase LC20 phosphorylation and force in smooth muscle

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

Discretizations of nonlinear dissipative evolution equations. Order and convergence.

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

Preparation of hydrolysates from tobacco stalks and ethanolic fermentation by Saccharomyces cerevisiae

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

Laparoscopic cholecystectomy in a patient with hemophilia B

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

New and simple procedure for the determination of muramic acid in chemically complex environments by gas chromatography-ion trap tandem mass spectrometry

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

Quantitative computed tomography in measurement of vertebral trabecular bone mass. A modified method

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

Genetic and nongenetic determinants of skeletal muscle glucose transporter 4 messenger ribonucleic acid levels and insulin action in twins

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

Estimation of HRV spectrogram using multiple window methods focussing on the high frequency power

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

Evaluation of the texture of fried potatoes

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
