This article reviews the problem of bleeding in connection with epidural/spinal anaesthesia, with special emphasis on the use of low molecular weight heparins for thromboprophylaxis. There are methodological difficulties to studying the problem in a scientifically correct way because of the rarity of the complication. However, from the data in the literature there are no indications of an increase
Objective. Our hypothesis states that the reactivity of the cutaneous microcirculation is reduced in patients with hypertension compared with healthy subjects. The objective was to verify the hypothesis by measuring microvascular function in hypertensive patients. Design. The study was a controlled trial with two arms: 15 hypertensives and 15 normotensives were enrolled, aged 30-60 years, and in h
Here, a conceptual model is presented for the development of Phytophthora disease in pedunculate oak. The model is presented using the causal loop diagram tool and gives an overview of how various abiotic and biotic factors, such as soil moisture, nutrient availability and mycorrhizal colonization, may affect the reproduction and the infective capacity of soil-borne Phytophthora species, the susce
The enzymes needed for galactomannan hydrolysis, i.e. β-mannanase, α-galactosidase and β-mannosidase, were produced by the filamentous fungus Aspergillus niger. The β-mannanase was purified to electrophoretic homogeneity in three steps using ammonium sulfate precipitation, anion-exchange chromatography and gel filtration. The purified enzyme had an isoelectric point of 3.7 and a molecular mass of
Parenthood is often considered a major factor behind gender differences in time allocation, especially between paid work and housework. This article investigates the impact of parenthood on men's and women's daily time use in Sweden and how it changed over the 1990s. The analysis is made using time diary data from the Multinational Time Use Survey (MTUS; N = 13,729) and multivariate Tobit regressi
A second species of the hitherto monotypic genus Microdonophagus Schauff is described as Microdonophagus levis sp. nov. The species is described from material collected at La Selva Biological Research Station in Costa Rica. Unlike the previously described species, Microdonophagus woodleyi Schauff, it is described from females only and the biology is not known. The addition of a second species of M
In eukaryotes, the number and rough organization of chromosomes is well preserved within isolates of the same species. Novel chromosomes and loss of chromosomes are infrequent and usually associated with pathological events. Here, we analyzed 40 pathogenic isolates of a haploid and asexual yeast, Candida glabrata, for their genome structure and stability. This organism has recently become the seco
In this work, a progress variable approach is used to model diesel spray ignition with detailed chemistry. The flow field and the detailed chemistry are coupled using the flamelet assumption. A flamelet progress variable is transported by the computational fluid dynamics (CFD) code. The progress variable source term is obtained from an unsteady flamelet library that is evaluated in each grid cell.
Purpose: To examine how the library user emerges in the context of the LibQUAL+ application in Sweden in 2004. Design/methodology/approach: The paper examines the following aspects: how the information control dimension is depicted in the results of the Swedish participants; how the information control dimension compares between the Swedish implementation and other libraries; the "new user" as he
BACKGROUND: Ventilator resetting is frequently needed to adjust tidal volume, pressure and gas exchange. The system comprising lungs and ventilator is so complex that a trial and error strategy is often applied. Comprehensive characterization of lung physiology is feasible by monitoring. The hypothesis that the effect of ventilator resetting could be predicted by computer simulation based on a phy
Interaction between cultural development and the natural environment is generally accepted. Holocene climate change is described as one of the main environmental factors behind a step-wise development of the cultural landscape in Northwest Europe. Seven periods of human impact changes-5900, 5500, 4500, 3800, 3000-2800, 1500 and 1100 cal. BP-are defined and compared with reconstructed climatic scen
Traditionally, traffic and activation of eosinophils in asthmatic airways are thought to take place during the late-phase allergic reaction. The present study tests the hypothesis that when eosinophils are present in the tissue before allergen exposure, as in chronically inflamed asthmatic airways, acute anaphylactic reactions initiate an eosinophil response. Using a guinea-pig allergic model, whe
This paper describes the development of a prototype product named MAGIC-HAND that has been developed to open bottles, jars and packages that require a twisting action. Its intended users are people with severe disabilities, who are not capable of using the current range of package opening tools. MAGIC-HAND is a kitchen accessory device that fits into standard kitchen furniture. The machine uses no
Rheological properties of isotropic solutions and gel structures of lysozyme-sodium dodecyl sulfate mixtures in water are investigated. Isotropic solutions behave as Newtonian fluids with very low viscosity values. For the lysozyme solutions the intrinsic viscosity and the Huggins coefficient were calculated on the basis of the Mooney equation. Above a certain yield stress value, the viscosity of
Presence of Stachybotrys chartarum in indoor environments has been linked to building-associated disease, however, the causative agents are unknown. Verrucarol (VER) and trichodermol (TRID) are hydrolysis products of some major S. chartarum mycotoxins, i.e. macrocyclic trichothecenes and trichodermin. We optimized gas chromatography-mass spectrometry (GC-MS) methods for detecting VER and TRID in S
We describe the migration performance of three long-distance migrating raptors, osprey Pandion haliaetus, honey buzzard Pernis apivorus and marsh harrier Circus aeruginosus, and one short-distance migrating raptor, common buzzard Buteo buteo based on Swedish ringing recoveries and satellite telemetry, respectively. Tracking by satellite can provide detailed information about the exact timing of mi
The appearance and functional properties are primordial in the quality assessment of semifinished fruit and vegetable products. These properties are often associated with shrunken, shriveled, darkened materials of poor rehydration ability after been subjected to air-drying—the most used drying method in the food industry. Fruits and vegetables are cellular tissues containing gas-filled pores that
This paper analyses the potential biomass Supply in the 15 EU countries (EU15), 8 new member states and 2 candidate countries (ACC10), plus Belarus and the Ukraine. The objective of this study is to make a more detailed assessment of the potential in Europe than previously undertaken. For this purpose five scenarios were designed to describe the short-, medium- and long-term potential of biomass f
Nationwide use and costs of anticholinergic drug for overactive bladder are unknown. We performed a nationwide study based on the Swedish Register on Prescribed Pharmaceuticals. From 2000 to 2007, there was a 68.8% increase in dispensed anticholinergic drugs in a population of 9 million. More than 93 million DDDs (calculated average maintenance dose per day) of anticholinergic drugs were dispensed
Several authors have reported promising results with vacuum-assisted closure therapy in poststernotomy mediastinitis. The aim of this study was to investigate the hemodynamic outcome following the application of six negative pressures on an open sternotomy wound. Six 70-kg pigs underwent median sternotomy followed by vacuum-assisted closure therapy. Six negative pressures (-50, -75, -100, -125, -1
