Background: Experimental studies suggest that surgical injury may up- or down-regulate nociceptive function. Therefore, the aim of this clinical study was to evaluate the effect of elective arthroscopically assisted knee surgery on nociceptive responses to a heat injury. Methods: Seventeen patients scheduled to undergo repair of the anterior cruciate ligament and 16 healthy controls were studied.
This article estimates the societal cost of alcohol consumption in Sweden in 2002, as well as the effects on health and quality of life. The estimation includes direct costs, indirect costs and intangible costs. Relevant cost-of-illness methods are applied using the human capital method and prevalence-based estimates, as suggested in existing international guidelines, allowing cautious comparison
This paper deals with transient finite elements modeling of magnetostriction. At first, a linear model is developed, which is verified by comparing the fourier transform of the step-response of the dynamical model to the, numerically differentiated, frequency response of the system. Then a non-linear relative permeability is assumed and at last, periodical collisions with a rigid wall are simulate
Each neural unit (cartridge) in the first optic ganglion (lamina) of the nocturnal bee Megalopta genalis contains nine receptor cell axons (6 short and 3 long visual fibres), and four different types of first-order interneurons, also known as L-fibres (L1 to L4) or lamina monopolar cells. The short visual fibres terminate within the lamina as three different types (svf 1, 2, 3). The three long vis
Monolith columns from macroporous polyacrylamide gel were grafted with polycations, poly(N,N-dimethylaminoethyl methacrylate) (polyDMAEMA), (2-(methacryloyloxy)ethyl)-trimethyl ammonium chloride (polyMETA) and partially quaternized polyDMAEMA prepared via treating polyDMAEMA-grafted columns with propylbromide. The polymer grafting degrees varied between 34 and 110%. The polycation-grafted monolith
Purpose: To describe the phenotype of an autosomal-dominant corneal dystrophy with an early onset of recurrent corneal erosions and development of subepithelial fibrosis in the cornea, and also to exclude genetic linkage to known corneal dystrophies with autosomal-dominant inheritance and clinical resemblance. Methods: We describe the medical history and clinical findings in individuals from a sev
Using core-level spectroscopy and density functional theory we show that a one-dimensional (1D) PtO2 oxide structure forms at the steps of the Pt(332) surface after O-2 exposure. The 1D oxide is found to be stable in an oxygen pressure range, where bulk oxides are only metastable, and is therefore argued to be a precursor to the Pt oxidation. As an example of the consequences of such a precursor e
The total heart volume variation (THVV) during systole has been proposed to be caused by radial function of the ventricles, but definitive data for both ventricles have not been presented. Furthermore, the right ventricle (RV) has been suggested to have a greater longitudinal pumping component than the left ventricle (LV). Therefore, we aimed to compare the stroke volume (SV) generated by radial f
Enforced expression of Hoxb4 dramatically increases the regeneration of murine hematopoietic stem cells (HSCs) after transplantation and enhances the repopulation ability of human severe combined immunodeficiency (SCID) repopulating cells. Therefore, we asked what physiologic role Hoxb4 has in hematopoiesis. A novel mouse model lacking the entire Hoxb4 gene exhibits significantly reduced cellulari
Alzheimer's disease (AD) and frontotemporal dementia (FTD) are characterized by progressive neuronal loss and microvacuolization, although with different distributions of cortical involvement. In contrast to AD there is no amyloid, senile plaques or tangles in FTD. The involvement of chromosome 19 in AD has been associated with apoliprotein E (ApoE) and the epsi4 gene frequency has been related to
We develop a density functional theory for infinitely long flexible and semiflexible polymers, as an appropriate simplification of the corresponding treatment of finite chains. We demonstrate that very long chains sometimes are required to reproduce even qualitatively correct limiting behaviors.
Germline mutations in BRCA1 and BRCA2 confer high risks of breast and ovarian cancer, but the average magnitude of these risks is uncertain and may depend on the context. Estimates based on multiple-case families may be enriched for mutations of higher risk and/or other familial risk factors, whereas risk estimates from studies based on cases unselected for family history have been imprecise. We p
Musculoskelecal conditions are a major cause of morbidity and evidence-based strategies - such as the European Action Towards Better Musculoskeletal Health - have been developed to reduce their incidence and impact on individuals and on society. This issue is based around that report. These strategies are inclusive of all major musculoskeletal conditions with recommendations for prevention and man
Radiative lifetimes of excited states of Zn I (3d(10)4sns S-3(1), n = 6-8; 3d(10) 4snd D-3, n = 4-7) and Zn II (3d(10) 4p P-2(1/2.3/2), 4d D-2(3/2,5/2), 3d(10)5S S-2(1/2)) have been measured using a time-resolved laser-induced fluorescence technique. Single- or two-step excitation of atoms and ions produced by laser ablation was employed. The experimental radiative lifetimes have been compared wit
This study examines the effect of foreign (Anglo-American) board membership on corporate performance measured in terms of firm value (Tobin's Q). Using a sample of firms with headquarters in Norway or Sweden the study indicates a significantly higher value for firms that have outsider Anglo-American board member(s), after a variety of firm-specific and corporate governance related factors have bee
