Four strains of gram-positive cocci with different combinations of positive binding of human proteins were investigated with respect to changes in physicochemical surface properties after specific protein binding. Staphylococcus aureus Cowan I, two group A beta-hemolytic streptococci, and one group G streptococcal strain were studied; they represented three different combinations of reactivity for
Intraspecific brood parasites lay their eggs in the nests of conspecifics. There are a number of methods for detecting intraspecific brood parasitism (IBP) in birds based on egg morphology. Here we test Eadie's (1989) method, which calculates the Euclidean distances between eggs in a given clutch in a three-dimensional space (weight, length and width). A parasitised clutch is predicted to contain
The transcription factor NFAT (nuclear factor of activated T-cells) is a cytosolic phosphoprotein that accumulates in the nucleus following dephosphorylation by the calcium (Ca2+)/calmodulin-dependent phosphatase, calcineurin. A defining feature of stimuli that induce NFAT nuclear accumulation/activation is a sustained increase in global intracellular Ca2+. Contrary to expectations, we have found
The invariant differential cross section for inclusive neutral-pion production in p+p collisions at roots=200 GeV has been measured at midrapidity (eta<0.35) over the range 1
A rapid (5.5 min) one-step whole blood C-reactive protein (CRP) magnetic permeability immunoassay utilizing monoclonal antibody conjugated dextran iron oxide nanoparticles (70 nm) as superparamagnetic labels and mixed fractions (1:1 ratio of 15-40 and 60 mu m) of polyclonal anti-CRP conjugated silica microparticles for enhanced sedimentation is described. In this one-step assay procedure, a whole
Organic carbon (C) in lakes originates from two distinct sources-primary production from within the lake itself (autochthonous supply) and importation of organic matter from the terrestrial watershed (allochthonous supply). By manipulating the C-13 of dissolved inorganic C, thereby labeling within-lake primary production, we examined the relative importance of autochthonous and allochthonous C in
Introduction: A state of hypercoagulation and fibrinolytic dysfunction is present in individuals with diabetes, which may contribute to disturbed skin microcirculation and impaired ulcer heating. We have previously reported an improved outcome of chronic diabetic foot ulcers during treatment with dalteparin. In the present study we investigated the effects of dalteparin on skin microcirculation an
Background/Aim: Several studies have described that oxytocin exerts stimulatory or inhibitory effects on gut functions. Recently, mRNA for oxytocin and its receptor was found throughout the entire human gastrointestinal (GI) tract. The aim of this study was to examine the cellular localization and distribution of the corresponding proteins. Material and methods: Full-thickness biopsies from 24 pat
Diagnosing myxoid soft tissue neoplasms can be challenging because of overlapping histologic features. Distinct chromosomal translocations have been identified in several myxoid sarcomas, including t(12;16)(q13;p11) FUS-DDIT3 in myxoid liposarcoma, t(7,-16)(q34;p11) FUS-CREB3L2 in low-grade fibromyxoid sarcoma, and t(9;22)(q31;q12) EWSRINR4A3 in extraskeletal myxoid chondrosarcoma. These recurrent
Bacterial activity was studied in a growth system containing Pinus contorta seedlings inoculated with different mycorrhizal fungi. Nylon nets enabled separation of soil compartments with extramatrical mycorrhizal hyphae from soil compartments with roots and mycelium. In three separate experiments bacterial activity, estimated as thymidine incorporation, was reduced in soils with Paxillus involutus
An association between human herpesvirus 8 (HHV8) and multiple myeloma ( MM) has been reported, though most studies have not confirmed such association. To follow-up on a previous prospective seroepidemiological study, where HHV8 tended to associate with MM risk, we linked five large serum banks in the Nordic countries with the Nordic cancer registries and 329 prospectively occurring cases of MM w
Aim To evaluate the instrument Measure of Processes of Care (MPOC) in a Swedish context. Methods The MPOC consists of 56 questions in the five scales: enabling and partnership; providing general information; providing specific information about the child; co-ordinated and comprehensive care; and respectful and supportive care. The questionnaire was translated into Swedish and distributed to 850 f
Aim: Migration has been suggested to promote large breeding ranges among birds because of the greater mobility of migratory compared to non-migratory species, but migration has also been suggested to restrict breeding ranges because of evolutionary constraints imposed by the genetical migration programme. We aim to investigate the association between migration and the breeding ranges of both land
Two barn swallows (Hirundo rustica) flying in the Lund wind tunnel were filmed using synchronised high-speed cameras to obtain posterior, ventral and lateral views of the birds in horizontal flapping flight. We investigated wingbeat kinematics, body tilt angle, tail spread and angle of attack at speeds of 414ms-1. Wingbeat frequency showed a clear U-shaped relationship with air speed with minima a
A comparative study on the bis(functionalization) of the Troger's base core by aromatic and heteroaromatic groups using palladium-catalyzed cross-coupling reactions is presented. Three different reactions, the Suzuki, Stille, and Negishi couplings, were investigated using Troger's base analogues equally substituted in the 2,8-positions with (HO)(2)B, Bu3Sn and ZnCl groups, respectively, as the met
