Sixty-one patients operated on for spinal stenosis, without a fusion, were studied retrospectively. Preoperative instability, as revealed by functional myelography, was found to predict a poor prognosis (P less than 0.01). Women had less favorable results (P less than 0.05). The "slipping" group was significantly more often radically decompressed than the "nonslipping" group (P less than 0.01). Po
Type 1 diabetes is a common, multifactorial disease with strong familial clustering (genetic risk ratio [{lambda}S] ~ 15). Approximately 40% of the familial aggregation of type 1 diabetes can be attributed to allelic variation of HLA loci in the major histocompatibility complex on chromosome 6p21 (locus-specific {lambda}S ~ 3). Three other disease susceptibility loci have been clearly demonstrated
Background. This case-control study was performed to evaluate whether adding first-trimester maternal serum testing to nuchal translucency measurement would improve the antenatal detection of Down's syndrome and decrease the number of women offered fetal karyotyping. Methods. In the Swedish Nuchal Translucency Trial 39,572 pregnant women were randomized to a routine scan at 12-14 gestational weeks
Galectins are implicated in a large variety of biological functions, many of which depend on their carbohydrate-binding ability. Fifteen members of the family have been identified in vertebrates based on binding to galactose (Gal) that is mediated by one or two, evolutionarily conserved, carbohydrate-recognition domains (CRDs). Variations in glycan structures expressed on glycoconjugates at the ce
The ability of dogs to adaptively modulate secretion by the exocrine pancreas to match changes in the amounts and sources of macronutrients is poorly understood. We evaluated the use of re-entrant pancreatic catheters as a non-terminal, temporary approach for the chronic collection of exocrine pancreatic secretion using unrestrained dogs fed diets differing in composition. Re-entrant catheters wer
The distribution of 50 species in the south Swedish provinces of Skane (Scania). Halland, Blekinge, Oland and Smaland has been mapped. Many of the species are endemic to southern Scandinavia and some are local endemics within the investigated area. However, there are also several species with a wider North European distribution. Within the area, the number of species shows a regular decline from t
Popular AbstractLandsbygdens landskap förändras ständigt. Ekonomi, teknik och politik används ofta för att förklara det som sker, men ingen av dessa krafter verkar direkt i landskapet. I praktiken är det beslut som fattas lokalt av enskilda brukare och markägare som sätter spår. Landskapet är där sammanvävt med den sociala miljön, och markanvändningen en integrerad del av den enskildes liv. Hur seFarmers and Landscape. Owners and farmers relations to their land, and the prospects for sustainable land use. In a transition towards sustainability, rural land use is of certain interest, owing to the environmental impact of modern farming and forestry, and also to its potential role in a recycling society. The prospects for sustainable land use depend on the farmers. Their conception of sustai
Methods of analysing and interpreting two-dimensional velocity field data in order to understand the scales of turbulence of bubbly two-phase flow were developed. Reynolds decomposition and large eddy simulation (LES) decompositions (low-pass filtering), in conjunction with proper orthogonal decomposition (POD) energy spectra analysis, as well as adjusted convective decomposition (constant convect
The thesis uses, as a starting point for a discussion of emergency response management, the problem of gradual coordinated adaptation of management functions in relation to an event and its dynamics. Empirical observations and analyses carried out in the research project show that important problemsolving processes not included in, and sometimes diverging from, planning and preparations frequently
To increase the overall ethanol yield from softwood, the steam pretreatment stage can be carried out in two steps. The two-step pretreatment process was evaluated from a techno-economic standpoint and compared with the one-step pretreatment process. The production plants considered were designed to utilize spruce as raw material and have a capacity of 200 000 tons/year. The two-step process result
A feed control strategy, based on estimated sugar concentrations, was developed with the purpose of avoiding severe inhibition of the yeast Saccharomyces cerevisiae during fermentation of spruce hydrolyzate. The sum of the fermentable hexose sugars, glucose and mannose, was estimated from on-line measurements of carbon dioxide evolution rate and biomass concentration by use of a simple stoichiomet
1 The effectiveness of antimuscarinic agents in the treatment of the overactive bladder (OAB) syndrome is thought to arise through blockade of bladder muscarinic receptors located on detrusor smooth muscle cells, as well as on nondetrusor structures. 2 Muscarinic M-3 receptors are primarily responsible for detrusor contraction. Limited evidence exists to suggest that M-2 receptors may have a role
Different functions for the programming of the cross flow in asymmetrical flow field-flow fractionation were studied with the aim to find the flow conditions most suitable for the molar mass distribution analysis of high molecular weight polysaccharides. A mixture of four differently sized pullulans covering the molar mass range 5.8 x 10(3)-1.6 x 106 g mol(-1) were used as a model sample. Two type
The levels of immune complex-like material in serum from 18 patients in connection with skin eruptions appearing during penicillin therapy were determined with a modified ELISA. Immune complex-like material could only be shown in the serum of 3 out of the 17 patients. However, according to ELISA results, the complexes appeared without the simultaneous presence of penicilloyl-specific antibodies. N
Objective: To compare the healthcare costs and effects of budesonide/formoterol in,a single inhaler with those of budesonide and formoterol monotherapies, and placebo, in a multinational study in patients with chronic obstructive pulmonary disease (COPD), National Heart, Lung and Blood Institute (NHLBI)/WHO Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages III or IV. Previous an
This paper reports on a parallel implementation of a general 3D multi-block CFD code. The parallelization is achieved by using three strategies. Firstly, it is done on dual-processor PC-clusters where Windows NT systems are running. A multi-thread programming model is adopted for the multi-block code, where one thread corresponds to a block. Shared-memory is used for the exchange of inner-boundari
