Short hospital stay augmented with education and home-based rehabilitation improves function and quality of life after hip replacement - Randomized study of 50 patients with 6 months of follow-up

Background Because of current cost restrictions, we studied the effect of a shorter hospital stay on function, pain and quality of life (QOL) after total hip replacement (THR). Patients and methods 50 patients from two hospitals were randomized into a study group (SG) of 27 patients receiving preoperative and postoperative education programs, as well as home visits from an outpatient team, and a c

Inter-tester reliability of a new diagnostic classification system for patients with non-specific low back pain

Most patients referred to physiotherapy with low back pain are without a precise medical diagnosis. Identification of subgroups of non-specific low back pain patients may improve clinical outcomes and research efficiency. A pathoanatomic classification system has been developed, classifying patients with non-specific low back pain into 12 different syndromes and three subcategories based on histor

Hearing thresholds in four-year-old children with weak or no transient-evoked otoacoustic emissions

Play audiometry is part of the general developmental screening covering 4-year-old children in the city of Malmo (Sweden). In an open study, 10% of the cohort was tested with transient-evoked otoacoustic emissions (TEOAEs), using the ILO88 system. The aim was to reveal a hearing loss exceeding 25 dB HL in 4-year-old children. As the first step in determining whether emissions can be used as an eff

Identification of the major proteoglycans from human myometrium

Background. During pregnancy and parturition a remodeling within the extracellular matrix of the cervix and the corpus uteri occurs, which is of fundamental importance to a normal labor. The aim of this study is to identify the major proteoglycans in corpus uteri of non-pregnant subjects. Methods. From human uterine tissue proteoglycans were extracted and purified using CsCl-density gradient centr

High-resolution In-beam Particle Spectroscopy - New Results on Prompt Proton Emission from 58Cu

Prompt proton decay lines in Cu-58 have been studied by means of high-resolution in-beam particle-gamma coincidence spectroscopy using the GAMMASPHERE Ge-detector array in conjunction with a dedicated set of ancillary detectors including four DeltaE-E silicon-strip telescopes. High-spin states in Cu-58 have been populated via the heavy-ion fusion-evaporation reaction Si-28(Ar-36, 1alpha1p1n) at 14

Evidence for noncollective oblate structures at high spin in Cs-123

High-spin states in Cs-123 were populated in the Ni-64(Ni-64,p4n) reaction at a beam energy of 265 MeV. Gamma-ray coincidences were measured using the Gammasphere spectrometer. Two additional bands have been placed in the level scheme and the four previously known bands have been extended to higher spin. At the highest spins, two of the bands show irregular level sequences. These structures of non

Hyaluronan is organized into fiber-like structures along migratory pathways in the developing mouse cerebellum

Hyaluronan is a free glycosaminoglycan which is abundant in the extracellular matrix of the developing brain. Although not covalently linked to any protein it can act as a backbone molecule forming aggregates with chondroitin sulfate proteoglycans of the lectican family and link proteins. Using neurocan-GFP as a direct histochemical probe we analyzed the distribution and organization of hyaluronan

Numerical Investigation of Turbulent Fluid Flow and Heat Transfer in Complex Ducts

Popular Abstract in Swedish Numeriska methoder har används för att beräkna turbulent strömning och värmeöverföring i komplexa kanaler med olika turbulens modeller.Th need for a reliable and reasonable accurate turbulence model without specific convergence problem for calculating duct flows in industrial applications has become more evident. In this study a general computational method has been developed for calculating turbulent quantities in any arbitrary three dimensional duct. Four different turbulence models for predicting the turbulent Reynolds stresse

Speciation and relationships in Dactylorhiza

Most of the Scandinavian members of the orchid genus Dactylorhiza are included in the D. incarnata/D. maculata polyploid complex. Molecular data obtained during the last decade have given a better understanding of evolutionary patterns in this complex and explain why it is taxonomically difficult. The data reveal that allotetraploids have been formed repeatedly by hybridization between the same pa

Primed B cells present type-II collagen to T cells.

Development of type-II collagen (CII)-induced arthritis (CIA) is dependent on a T-cell mediated activation of autoreactive B cells. However, it is still unclear if B cells can present CII to T cells. To investigate the role of B cells as antigen-presenting cells (APCs) for CII, we purified B cells from lymph nodes of immunized and nonimmunized mice. These B cells were used as APC for antigen-speci

Persistent organochlorine pollutants in children working at a waste-disposal site and in young females with high fish consumption in Managua, Nicaragua

The aim of this study was to assess persistent organochlorine pollutant (POP) levels in serum collected from children (11-15 years old) working and sometimes also living at the municipal waste-disposal site in Managua, located at the shore of Lake Managua, and in nonworking children living both nearby and also far away from the waste-disposal site. The influence of fish consumption was further eva
