Popular Abstract in Swedish Kontrollmekanismerna rörande blodcirkulationen i den mänskliga fetoplacentära enheten är fortfarande inte fullständigt kända, trots genomgripande undersökningar. Det är dock känt att den är viktig för att kunna bibehålla en normal graviditet och för att kunna frambrigna ett friskt nyfött barn. Om kontrollen brister kan utgången försämras i form av tillstånd såsom preeklIn this present study the population of endothelin-like receptors in the human umbilical artery was examined in vitro in different parts of the umbilical cord. Immunohistochemistry revealed ETB receptors in the endothelium and an uneven distribution of ETA receptors in the smooth muscle of the arterial wall, when comparing different parts of the umbilical artery. ET-1 induced vasoconstriction wa

The Swedish inventor Christopher Polhem had an idea of a universal language which occupied him for decades, i.e. a perfect language which can be spoken and understood by everyone, by the educated and non educated alike, and no matter where they come from. Polhem did a large number of sketches for such a universal language, among others a manuscript concerning a lunar language, which was completely

A capillary gas chromatographic (GC) method using selected-ion monitoring (SIM) was developed for the analysis of cotinine (C.A.S. No. 486-56-6) in human urine. The method is based on basic extraction of cotinine from 2 ml of urine into dichloromethane. After evaporation of the dichloromethane solution to dryness, 100 microliters of toluene were added, prior to GC-mass spectrometric (MS) analysis.

A short summary of the present status of prompt particle decays in the mass A similar to 60 region is presented. It includes recent results from a GAMMASPHERE experiment, which aimed at the combined high-resolution spectroscopy of light charged particles and gamma-rays to allow for more detailed studies of known decays and the identification of new cases of discrete prompt proton and a-particle em

OBJECTIVE: To compare survival of patients with breast cancer who had never smoked, were smokers, and who were ex-smokers. DESIGN: Observational study. SETTING: City of Malmo, Sweden. PATIENTS: 792 patients with breast cancer diagnosed between 1977-1986 in the Malmo mammographic screening trial. INTERVENTIONS: Follow-up of breast cancer cases through record-linkage with the Swedish Cause of Death

This thesis explores the changing patterns of employment and income assimilation among male immigrants to Sweden. In brief, the results of this work are that immigrants have been facing an increasingly difficult time integrating into the Swedish economy. This difficulty has not been caused by decreasing “quality” of the newer immigrant cohorts, as has often been the argument in the literature. Rat

Popular Abstract in Swedish I debatterna om sociala och ekonomiska frågor under 1800-talets första hälft utvecklades grundvalarna för de förhållningssätt till arbetslöshetsfrågan som sedan återkommit i skilda former. Det gällde t.ex. det perspektiv som betonade politikens roll och behovet av statlig intervention för att stimulera produktion och sysselsättning. Det gällde också det renodlade marknaLabour market policy has been at the forefront of economic and political debate in Sweden during the postwar period. Much research effort has been focused on the evolution of labour market policy and its historical roots. The time-perspective has often been narrow, however, and has very seldom extended to include the period prior to the first two decades of the twentieth century. This study emphas

In this study changes in the diameter and compliance of the distal abdominal aorta (76 healthy Caucasian males, 5-71 years old) were determined non-invasively and related to age by means of an ultrasound phase-locked echo-tracking system. The diameter of the aorta increased not only in the period between 5 and 25 years of age, but also by about 30% between the ages of 25 and 71. The pressure diame

Experiments were performed to define quantitatively the substrate (K(+) and Cl(-)) dependence of the transport function (production of equally large and oppositely directed K(+)and Cl(-) flows/currents) of an earlier (Theander et al., 1999) identified electroneutral K-Cl cotransporter in the slowly adapting stretch receptor neurone of the European lobster. The experiments were based on microelectr

The activity of titania based copper and platinum monolithic catalysts in the reduction of nitrogen oxides was studied with exhaust gases from a Diesel engine injecting fuel as reductant. Combining both catalysts, a two-stage system was designed, studying the influence of the copper catalysts composition on its performance with synthetic gas mixtures. The influence of reactants concentration and o

By studying the responses to the last expulsion for "apostasy" from the Swedish National Church in 1858, this article examines how an international Protestant identity was constructed in mid-nineteenth-century Europe. It is the argument of this study that a comprehensive identity - including both evangelicals and theological progressives - could be built around the notion of religious liberty. The

Urinary cotinine (U-cotinine) as a biomarker of environmental tobacco smoke exposure was evaluated in 14 children (age 4-11 y) and in 7 adults who were exposed to environmental tobacco smoke at an air nicotine level of 110 mg/m3 for 2 h in a bus. Nicotine in air and U-cotinine were measured by gas chromatography/mass spectrometry before, during, and after the experiment. U-cotinine rose rapidly to
