Potassium diperiodatocuprate-initiated graft polymerization was found to be an efficient and convenient method for grafting of acrylic acid (AAc) onto superporous polyacrylamide gels, so called cryogels (pAAm cryogels). It was possible to achieve grafting degrees as high as 70% with about 25% yield of grafted polymer with respect to the initial amount of monomer. The superporous structure of the c

The concept of proximity has its origins at the beginning of the years ’90 in France with the studies from the Group of the Dynamics of the Proximity. The importance of the territorial proximity for the development is considered basically through studies centred in the analysis of industrial dynamic and innovative environments. Its relationship with the local development in poor rural areas has be

BACKGROUND: The TT virus (TTV) is a newly identified blood-borne virus. Its association with disease is still unknown, and screening of blood donors has not been implemented. Several genotypes of the TTV have been identified. STUDY DESIGN AND METHODS: Three hundred seventy healthy blood donors were randomly selected and tested for TTV by the PCR method. Sequencing of a part of the genome was perfo

Macro- and microphase separation of compatibilizing graft copolymers in melt-mixed polystyrene/polyamide-6 blends was studied by transmission electron microscopy and thermal analysis. Three different graft copolymers with main chains of polystyrene and side chains of poly(ethylene oxide) were used as additives at various concentrations. The polyamide-6 domain sizes decreased with increasing amount

En sammanställning av etiologin till akut leversvikt hos patienter i Sverige 1994–2003 visade att paracetamolförgiftningar (42 procent) och idiosynkratisk, läkemedelsinducerad leverskada (15 procent) var de vanligaste orsakerna. Prognosen varierade stort beroende på etiologin. Sammanlagt 13 procent av patienterna med paracetamolförgiftning avled, och 5 procent transplanterades. Av patienterna medA recent study in Sweden on patients with acute liver failure (ALF) 1994-2003 demonstrated that the most common causes were paracetamol toxicity (42%) and idiosyncratic drug reactions (15%). In 11% of cases of ALF no definite etiology could be established. Among patients with paracetamol toxicity, the spontaneous survival without liver transplantation was 82% compared to 49% in patients with react

The uterine arteries and arteries in the wall and core of myomas were examined with transvaginal color and spectral Doppler ultrasound in 28 premenopausal and 17 postmenopausal women with uterine myomas. Eighteen premenopausal women and 100 postmenopausal women without myomas served as the controls for uterine artery Doppler measurements. The respective median time-averaged maximum velocity and pu

The distribution of 47 species in the south Swedish provinces of Skane (Scania), Halland, Blekinge, Oland and Smaland has been mapped. Most of these species are endemic to central Fennoscandia and many reach their southern distribution limits in the investigated area. However, there are also some local endemics as well as some species with a wider north European distribution. Within the area, the

Background and Purpose-A low risk of recurrent stroke and death after lacunar infarction has previously been reported, but follow-up has been limited to less than or equal to5 years. Methods-One hundred eighty patients with pure motor stroke, collected between 1983 and 1986 from a hospital-based stroke registry, were followed up until at least 10 years after the index stroke. Two patients were los

Frontal eyes of crustaceans (previously Called nauplius eye and frontal organs) are usually simple eyes that send their axons to a medial brain Centre in the anterior margin of the protocerebrum. Investigations of a large number of recent species within all major groups of the Crustacea have disclosed four kinds of frontal eyes correlated with taxonomic groups and named after them as the malacostr

En fältstudie på åtta mastarbetare utfördes under februari i Svealand och Norrland. Mastarbetarnas aktiviteter observerades under en vanlig arbetsdag i masten och hudtemperaturen på sju ställen på kroppen, kroppstemperatur och hjärtfrekvens registrerades kontinuerligt. De fick också skatta sin temperaturupplevelse och ansträngningsgrad flera gånger under dagen. Lufttemperaturen varierade mellan -1Désirée Gavhed, Kalev Kuklane, Ingvar Holmér. Work on masts in cold conditions. Arbetslivsrapport 1999:22. Eight tower operators were studied in February during their ordinary duties in masts in four regions of Sweden. The activities of the workers were observed during a full working day and the skin temperature at seven spots, body temperature and heart rate were measured continuously. They also

To determine the additional stabilizing effect of unilateral hip fixation on external lumbar supports, nine patients with a posterolateral lumbosacral fusion without internal fixation were examined by roentgen stereophotogrammetric analysis. The roentgen stereophotogrammetric analysis was performed with the patients in supine and erect positions 1 month after surgery, that is, before fusion consol

A second workshop on small-x physics, within the Small-x Collaboration, was held in Lund in June 2002 with the aim of over-viewing recent theoretical progress in this area and summarizing the experimental status.

Blood samples from 141 children and adolescents were used to evaluate differences between commercial kits and radioimmunoassay (RIA) methods for detecting thyroid autoantibodies. Thyroglobulin autoantibodies (Tg-Ab) were analyzed with a hemagglutination kit and a RIA; thyroid peroxidase autoantibodies (TPO-Ab) were measured with a gelagglutination assay and a RIA. The result; of the antibody tests

The effects of two sympathomimetic drugs on mucociliary activity and mucosal blood flow in the rabbit maxillary sinus were investigated by using a photo-electric technique (mucociliary activity) and laser Doppler flowmetry (blood flow). The responses produced were compared with effects of ligation of the external carotid artery. The alpha 1-agonist phenylpropanolamine (0.1-100 micrograms/kg) had n
