In 98 patients undergoing elective vascular surgery, specimens for bacterial cultures were obtained from urine, ischaemic ulcers, incisional wounds and the implanted grafts. Wound and graft infections were registered and compared with the results of these cultures and suspected risk factors in an attempt to find the source of infections. Antibiotic prophylaxis with cefuroxime was given for 24 h be

Two ring handles were found in Uppåkra by the archaeological excavations. The first one was found by metal detector survey near the church of Uppåkra and was assumed to have beonged to the medieval Church that in the 19:th cent. was replaced by the modern church. The other ring handle was found by in one of the foure large postholes in the cult house and was dated to 500-600 A.D. The ring handles

The paper starts with a theoretical discussion about individual versus collective behavior in urban society. The classical theories of Ferdinand Tönnies and Georg Simmel are starting points in a discussion which ends in modern theories of urbanism as a way of life. In modern urbanism three spheres of life are distinguished; the private sphere, the neighborhood sphere and the public sphere. Especia

Samhällets krav vad gäller förebyggande brandförsvar är i första hand inriktade på omsorgen om människors säkerhet och i andra hand på egendomsskyddet. I det först nämnda fallet är det brandens tidiga skede som är av intresse medan den fullt utvecklade, långvariga branden har störst inverkan på egendomsskydd. Vad gäller egendomsskyddet har det sedan länge funnits internationellt erkända metoder fö

1. The present study was undertaken to elucidate the effect of propofol on sympathetic neurotransmission in isolated human omental vessels. 2. Segments of both arteries and veins were exposed to 0, 10(-7), 10(-6), 10(-5) or 10(-4)M propofol, and studied in vitro to determine effects on: (i) isometric tension after electrical field stimulation (EFS) or after exogenous administration of noradrenalin

Knowledge of hiv/aids, exposure to hiv/aids information and appreciation of given information was studied, by a questionnaire, among 326 Kenyan and 146 Swedish teenage school students in 1994. The aim of the study was to examine differences and similarities in knowledge in the two populations and to examine which sources of information about hiv and aids the respondents had been exposed to and whi

The regional sensitivity of different vascular beds to i.v. CGRP was investigated in the albino rabbit by using the microsphere method. Experiments were performed without pre-treatment on both conscious and pentobarbital-anaesthetized animals. In addition, in one series on conscious animals, rabbits were pre-treated with indomethacin in order to reduce the formation of prostaglandins. In another s

B cell differentiation is controlled by a complex network of lineage-restricted transcription factors. How perturbations to this network alter B cell fate remains poorly understood. Here we show that classical Hodgkin lymphoma tumor cells, which originate from mature B cells, have lost the B cell phenotype as a result of aberrant expression of transcriptional regulators. The B cell-specific transc

The aim of this study was to determine the risk and burden of vertebral fractures judged as those coming to clinical attention and as morphometric fractures. Incidence and utility loss were computed from data from Malmo, Sweden. Clinical fractures accounted for 23% of all vertebral deformities in women and for 42% in men. The average 10-year fracture probability for morphometric fractures increase

Despite having the same snowmelt processes, snowpacks in urban environments experience a range of conditions different from those of rural areas. Melt is intensified at some sites due to greater radiative energy. Shading, however, can reduce radiation and melt at other sites. Changes to the radiation balance and snowpack processes have been investigated. A physical snowpack model was developed and

The N- and C-terminal halves of the heme A synthase polypeptide of Bacillus subtilis, and many other organisms, are homologous. This indicates that these enzyme proteins originate from a tandem duplication and fusion event of a gene encoding a protein half as large. The ape1694 gene of the hyperthermophilic archaeon Aeropyrum pernix encodes a protein that is similar to the hypothetical small primo

Ferric and copper hexacyanoferrates (PB and CuHCF, respectively) were electrodeposited on glassy carbon electrodes providing a suitable catalytic surface for the amperometric detection of hydrogen peroxide. Additionally glucose oxidase was immobilized on top of these electrodes to form glucose biosensors. The biosensors were made by casting glucose oxidase-Nafion layers onto the surface of the mod

Using Burt's envelope function theory and the scattering matrix method, we investigate the hybridized electron-hole Landau levels in strained InAs/GaSb quantum wells sandwiched between wide-gap AlSb barrier layers under electric and a quantizing magnetic fields applied perpendicular to interfaces. At zero magnetic field, in the structures studied here, the lowest electron level in the InAs layer l
