Calcium-sensitivity of contraction, force-velocity relation and ATP hydrolysis rate at different pH (6.2-7.8) were investigated in skinned smooth muscle preparations from the guinea pig taenia coli. Varied free-calcium levels were buffered by 4 mM BAPTA (1,2-bis(2-aminophenoxy)-ethane-N,N,N'N'-tetraacetic acid) which has calcium binding properties little affected by pH. A small increase of calcium

This article presents a study of the metaphor as instrument for the direct perception of events. Its major hypothesis refers to the event structure embedded in the ground of a metaphor. Since the ground is implicit in the linguistic manifestation, an invariant representation of textual movement patterns is assumed to capture the event structure. Experimentally, it is demonstrated that an event is

Abstract in Norwegian Leukotriener syntetiseres fra arakidonsyre. De er potente proinflammatoriske mediatorer og bidrar til hyperreaktivitet i luftveiene. Antileukotriener er en ny gruppe medikamenter ved astma, og Zafirlukast, en leukotrienreseptorantagonist, er nå registrert for behandling av mild til moderat astma i Irland og Finland. Vi har foretatt en litteraturstudie vedrørende antileukotriLeucotrienes are synthesized from arachidonic acid. They are potent proinflammatory mediators that contribute to bronchial hyperreactivity. Antileukotrienes constitute a new group of antiasthmatic drugs. Zafirlucast, a leukotriene receptor antagonist, is now registered in Ireland and Finland for the treatment of mild to moderate asthma. We have studied the literature on antileukotrienes and have f

Objective: Interstitial laser coagulation (ILC) of the prostate is a minimally invasive method for treating symptomatic benign prostatic enlargement (BPE). We performed a prospective randomized study to compare the clinical outcomes of ILC and transurethral resection of the prostate (TURP). Material and Methods: Between December 1997 and February 2000, 38 patients with moderate-to-severe symptomat

The possible teratogenic effect of erythromycin therapy, noted previously, was studied. Women who had taken erythromycin or penicillin V in early pregnancy and their infants were studied, using the Swedish Medical Birth Register where information on drug use during pregnancy was recorded based on interviews in early pregnancy. The risk for any congenital malformation after erythromycin therapy (bu

The form factor of A(o)(b) baryons is estimated using 3.46 x 10(6) hadronic Z decays collected by the DELPM experiment between 1992 and 1995. Charmed A(c)(+) baryons fully reconstructed in the pK(-)pi(+), pK(o)(s), and Api(+)pi(+)pi(-) modes, are associated to a c S lepton with opposite charge in order to select A(o)(b) --> A(c)(+)l(-)v(l) decays. From a combined likelihood and event rate fit to t

1. Strips from the follicle wall of bovine ovaries were incubated in Krebs-Ringer solution containing 3H-noradrenaline for measurement of transmitter liberation during electrical field stimulation (5 Hz frequency, 1 ms pulse duration, 10 V between the electrodes). The effects of noradrenaline as well as selective alpha-adrenoreceptor agonists and antagonists were studied on the electrically induce

Popular Abstract in Swedish Förbättrad patientsäkerhet och omvårdnad av patienter med höftraktur Intervention granskad i det nationella kvalitetsregistret RIKSHÖFT Varje år drabbas ca 18 000 personer i Sverige av höftfraktur efter fall. Höftfraktur är ett samlingsnamn för två frakturtyper i den övre delen av lårbenet. Den ena frakturtypen är lokaliserad till lårbenshalsen (cervikal fraktur) och dAim: Hip fractures are common and costly. The overall aim of this thesis was to explore how different clinical pathways influence safety and quality of care among patients with a hip fracture and to test the usefulness of the national quality register RIKSHÖFT as a working tool. The aim in paper I was to improve the outcome of patients with a hip fracture through optimized preoperative pain relief

ydrophobically modified polymers (HM-P) typically behave as thickeners in a wide range of systems. The thickening effect in an aqueous solution of this kind of polymer depends on intermolecular hydrophobic associations and also on chain entanglements if the polymer concentration is significantly above the overlap concentration. In the present investigation a rather short end-capped polymer has bee

This article describes an evaluation of six different methods for prioritizing software requirements. Based on the quality requirements for a telephony system, the authors individually used all six methods on separate occasions to prioritize the requirements. The methods were then characterized according to a number of criteria from a user's perspective. We found the analytic hierarchy process to

Birdsong is one of the main models in sexual selection studies. Most investigations focused on oscines in which male song and female preference learning occur. Yet, some non-oscines are well suited for such studies as well. In Columbidae song learning does not occur. However, like in oscines, song is involved in inter- and intra-sexual interactions. Surprisingly, experimental evidence of female so

We analyze the impact of mutual coupling on the capacity of MEMO systems with compact antenna arrays. Existing studies present conflicting views on the effect of mutual coupling. This is, in part, due to their different scopes and underlying assumptions of the system setups. In this paper, we aim to give a comprehensive picture by first examining the impact of mutual coupling on three capacity-rel

Popular Abstract in Swedish En god näringstillförsel är viktigt för att ett barn ska växa och utvecklas tillfredställande. De första 2-3 åren innebär en kraftig tillväxt och optimalt kostintag är därför extra viktigt under denna perioden. Barnets vikt tredubblas först året och längden ökar med 50 %. Hjärnan har en kraftig tillväxt de första 3 åren. Således är näringsbehoven relativt sett störst deThe overall aim of this thesis was to describe the prevalence of iron deficiency (ID) and factors influencing iron status and iron intake among otherwise healthy children. The specific aim in paper I+II was to describe the prevalence of ID among 2 ½-year-old children in relation to intake of cow's milk and follow-on formula. The design in the first two papers were cross-sectional and 367 2 ½-year-
