Graphite electrodes have been modified with different forms of horseradish peroxidase (HRP). These included native HRP, wild-type recombinant HRP, and two single-point recombinant HRP mutants, N70V and N70D. The mediator-less response of these electrodes to H2O2 was studied indicating that electrodes modified with recombinant HRP forms are more stable than those modified with native HRP. Various i
The role of nitric oxide (NO) in spinal cord injury (SCI)-induced motor dysfunction, breakdown of the blood-spinal cord barrier (BSCB), edema formation, and cell injury was examined using a pharmacological approach. We used three types of nitric oxide synthase (NOS) inhibitors: a nonselective blocker, L-NAME; an irreversible inhibitor of all isoforms of NOS, L-NMMA; and a long-term competitive inh
The aim was to examine tissue expression of Ku protein in lower lip salivary gland (LSG) biopsies from cases of primary Sjogren's syndrome (SS) and from normal subjects. Methods: immunohistochemistry was used with antibodies to Ku70/86 and also Ki67, PCNA and p53. In addition, the Klenow method was applied in order to detect evidence of apoptosis. Sections of hyperplastic tonsil served as addition
We investigate some recent measurements of Fermi-Dirac correlations by the LEP collaborations indicating surprisingly small source radii for the production of baryons in e(+)e(-) annihilation at the Z(0) peak. In hadronization models there is besides the Fermi-Dirac correlation effect also a strong dynamical (anti-) correlation. We demonstrate that the extraction of the pure FD effect is highly de
One hundred consecutive patients with atlanto-axial dislocation(s) were subjected to posterior occipito-cervical fusion and followed up to 16 1/2 years postoperatively (mean: 4 1/2 years). The mean age at surgery was 60.3 years. At the time of follow-up, 45 patients had died, mostly due to cardiopulmonary disease. Out of the 100 patients, 67% showed a major improvement and in an additional 14% the
The decision how to allocate marginal resources to reproduction and growth can have important effects on associated life-history parameters as well as on population dynamics. In addition to showing variation among individuals in a population, such allocation rules may be either condition-dependent or fixed in different individuals. While many studies on anuran amphibians have focused on egg number
This is an annotated translation, with an introduction, of Mao Zedong's instructions on current educational work at an informal discussion with the heads of Education Departments from seven Chinese provinces and municipalities on 7 March 1957
High-spin terminating bands in heavy nuclei were first identified in nuclei around Er-158(90). While examples of special terminating states have been identified in a number of erbium isotopes, almost nothing is known about the states lying beyond band termination. In the present work the high-spin structure of Er-157 has been studied using the Gammasphere spectrometer. The subject of triaxial supe
Allergic rhinitis is a predisposing factor for developing clinical asthma. Moreover, allergic rhinitis is often associated with bronchial hyperresponsiveness (BHR). We hypothesise that patients with asthma have more small airway involvement than those with allergic rhinitis and BHR alone. The aim of this study was to assess peripheral and proximal NO concentration in rhinitic subjects, and to corr
Under grävningssäsongen 2003 anträffades en ansamling med ben (U60527)(Fig. 1) strax norr om det numera berömda kulthuset i Uppåkra (fig. 2). Fyndet gjordes inom området för en offertradition från järnåldern där man hittat större mängder rituellt förstörda lans- och spjutspetsar liksom andra vapendetaljer spridda över en omkring 70 m2 stor yta (Helgesson 2004:224ff). Benansamlingen som bestod av o
The thesis is a reception study and the focus of the research is on what happens during the reading process when an upper secondary school class reads fiction. The theoretical basis consists of theories of reading as transaction and the envisionment-building and dialogic classroom. A process-based and relational perspective on reading, writing and oral exchange in teaching has been central. The e
A new sub-micron beamline for high-resolution nuclear microprobe applications has been constructed at the Lund nuclear microprobe facility. The design and construction of the main experimental chamber.. sample viewing system and computer controlled precision sample stage movement is presented in this paper. The chamber is especially designed for using a large area annular HPGe detector. The advant
