The results of Swanson and Avanta metacarpophalangeal joint arthroplasties in rheumatoid patients were compared in a prospective, randomized study of 30 patients (120 implants). At 2-year follow-up, grip strength was measured, hand function was assessed with the Sollerman test and the subjective outcome was determined with visual analogue scores. With both implants ulnar deviation and flexion defo
Osteoprotegerin (OPG), a secreted member of the tumor necrosis factor receptor family, is a potent inhibitor of osteoclast activation and differentiation. In animal models OPG prevents bone loss, and in humans bone resorption can be reduced by injections of OPG. OPG may also play a role in cardiovascular disease since mice lacking the OPG gene display arterial calcification. In a screening effort
Pain is a common problem for older persons who need professional help for their daily living. In this study 94 older persons (75+) in persistent pain were compared with 52 care providers concerning the pain management methods they had used/administered during the previous week and how helpful they perceived these methods to be. interviews were based on 16 items from the original version of the pai
A generalized scattering matrix method is presented for spin-dependent electron transport in a quantum waveguide under the modulations of local magnetic field and/or spin-orbit interaction (SOI). All the required Hamiltonian matrices are expressed in terms of a common basis spanned by the products of the transverse spatial eigenstates and the spin eigenstates of the leads. In the formulation we ha
The Fra a I allergen in strawberry (Fragaria ananassa) is homologous to the major birch pollen allergen Bet v 1, which has numerous isoforms differing in terms of amino acid sequence and immunological impact. To map the extent of sequence differences in the Fra a I allergen, PCR cloning and sequencing was applied. Several genomic sequences of Fra a 1, with a length of either 584, 591 or 594 nucleo
A partition study with peptides and recombinant proteins in poly(ethylene glycol)4000-potassium phosphate aqueous two-phase systems has been performed. The aim was to study to what extent the insertion of charged residues could affect protein partition in addition to the already observed effects of tryptophan residues. The model proteins used are based on a staphylococcal protein A derivative, Z,
The metastable CH2I-I and CHI2-I isomers formed by UV photolysis of CH2I2, and CHI3 transfer methylene and iodomethylene groups, respectively, to a variety of cycloalkenes, leading to their cyclopropanation. More than a 100-fold increase of the reaction rate with increasing solvent polarity suggests a dipolar transition state. The fastest second-order rates observed were in CH3CN. However, CH2Cl2
The blood concentrations of lidocaine and its main active metabolites, methylethylglycinexylidide (MEGX) and glycinexylidide (GX), were measured in 24 newborn infants during anticonvulsive treatment with an iv infusion of lidocaine. After a bolus dose of 1.5-2.2 mg/kg and continuous infusion of lidocaine (4.7-6.3 mg/kg/h) there was accumulation of the drug and MEGX within 24 h. After termination o
Symptomatic portal hypertension (PH), is often treated by transjugular intrahepatic portosystemic shunt (TIPS). Patients with PH, caused by prehepatic portal vein occlusion, require recanalization with stent or stent-graft often followed by additional TIPS. Stent-grafts used for TIPS, may occlude the outflow from the adjacent hepatic vein, potentially disturbing the circulation through the adjoini
Objective. To investigate the adjusted relative risk of cardiovascular disease (CVD) events in offspring of parents with cardiovascular mortality before 75 years. Setting. The city of Malmö, Sweden. Design. A follow-up study based on register linkage analyses. Subjects and methods. In the Malmö Preventive Project (MPP), a total of 22 444 men and 10 902 women attended the screening programme bet
A literature review and a questionnaire study with 62 participants were carried out to provide recommendations on the design of a set of evacuation systems for road tunnels: 1) Traffic Information Sign (TIS) - message and size of the sign (large or small), colour scheme, and use of pictograms and/or flashing lights, 2) Emergency exit portal layout - colour scheme, 3) Acoustic systems - voice messa
"It´s difficult, there is a big grey zone”. A qualitative study of preschool teachers’ thoughts on the obligation to report There are several professionals in Sweden who are obligated by law to report when they suspect a possible case of a child being maltreated. The aim of this study was to capture preschool teachers’ thoughts on what that obligation means. How does it work in the field? D
