Cerebral Blood Flow Alterations in Pain-Processing Regions of Patients with Fibromyalgia Using Perfusion MR Imaging.

BACKGROUND AND PURPOSE: Widespread pain sensitivity in patients with FM suggests a CNS processing problem. The purpose of this study was to assess alterations in perfusion as measured by DSC in a number of brain regions implicated in pain processing between patients with FM and healthy controls. MATERIALS AND METHODS: Twenty-one patients with FM and 27 healthy controls underwent conventional MR i

Joint owned companies as instrument of Local Government: Comparative evidence from the Swedish and Italian water sector

The combination of features from the public and private sectors in jointly owned companies imposes challenges to the governance and control mechanisms of these organisations, which have been criticised for lacking accountability. Where there is fragmented ownership, the interests of different owners need to be coordinated. The aim of this article is to consider how such companies can be governed i

Critical role of p38 mitogen-activated protein kinase signaling in septic lung injury.

OBJECTIVE: Leukocyte-mediated tissue damage is a key feature in septic lung injury, although the signaling mechanisms behind pulmonary recruitment of leukocytes remain elusive. The aim of the present study was to define the role of p38 mitogen-activated protein kinase (MAPK) signaling in septic lung injury. DESIGN: Prospective experimental study. SETTING: University hospital research unit. SUBJECT

Fast antenna selection algorithms for MIMO systems

We consider the capacity of multiple-input-multiple-output (MIMO) systems with reduced complexity. One link end uses all available antennas, while the other chooses the "best" L out of N antennas. The selection of the optimum antenna subset requires an exhaustive search of all possible combinations, involving (/sub L//sup N/) computations of determinants of size L /spl times/ L, which can become p

Comprehensive evaluation of PCA-based finite element modelling of the human femur

Computed tomography (CT)-based finite element (FE) reconstructions describe shape and density distribution of bones. Both shape and density distribution, however, can vary a lot between individuals. Shape/density indexation (usually achieved by principal component analysis—PCA) can be used to synthesize realistic models, thus overcoming the shortage of CT-based models, and helping e.g. to study fr

Orientalist Social Work: Cultural otherization of Muslim Immigrants in Sweden

This aim of this article is to critically examine how the concept of culture is used in Sweden to explain the “failure” or the difficulties that Muslim immigrant families are experiencing with regards to their integration into the dominant society. Whereas, the Swedish society is often represented as ‘modern’, ‘progressive’, and ‘democratic’, immigrants with Muslim backgrounds are predominately de

A cross-linked hyaluronic acid hydrogel (Healaflow(®)) as a novel vitreous substitute.

Vitrectomy requires the substitution of the natural vitreous, as well as tamponading of retinal breaks. Clinically available alternatives such as gas and silicone oil have side effects such as inflammation, secondary glaucoma, cataract, and a need for head posturing. In this study, a hydrogel of cross-linked sodium hyaluronic acid (Healaflow(®)) is evaluated for use as a novel vitreous substitute.

Simvastatin protects against cholestasis-induced liver injury.

Background: Bile duct obstruction is associated with hepatic accumulation of leukocytes and liver injury. The aim of this study was to evaluate the effect of simvastatin on cholestasis-induced liver inflammation and tissue damage. Experimental approach: C57BL/6 mice were treated with simvastatin (0.02 and 0.2 mg.kg(-1)) and vehicle before and after undergoing bile duct ligation (BDL) for 12 h. Leu

Direct and inverse scattering in the time domain for a dissipative wave equation. Part 3: Scattering operators in the presence of a phase velocity mismatch

The direct scattering problem for an inhomogeneous lossy medium is examined for the one-dimensional case in which the phase velocity profile is discontinuous at the boundaries of the medium. Scattering operators (or impulse responses) and propagation operators are defined and equations that govern their behavior are developed. Knowledge of the scattering kernels for one round trip in the medium im

Maternal Use of Antipsychotics in Early Pregnancy and Delivery Outcome.

The effect of various antipsychotics during pregnancy has repeatedly been studied, but for most atypical antipsychotics, only little information is available. We identified from the Swedish Medical Birth Register 2908 women who had reported the use of any antipsychotic or lithium in early pregnancy and studied malformation rates with data also from the Register of Congenital Malformations and the

Cesarean section scar defects: agreement between transvaginal sonographic findings with and without saline contrast enhancement.

OBJECTIVES: To determine the agreement between transvaginal ultrasound examinations performed before and at saline contrast sonohysterography (SCSH) with regard to number, size and shape of Cesarean section (CS) scar defects. METHODS: In all, 108 women underwent transvaginal ultrasound examination with SCSH at least 6 months after CS: 68 had undergone one CS, 32 two CSs and eight women had undergo
