Background. Nausea and vomiting in pregnancy (NVP) is a common complaint but risk factors for NVP are not well characterized. Methods. Occurrence of NVP was studied by questionnaires given to pregnant women at their first visit to the antenatal care unit and were returned around gestational week 28. Results. Analysis of 3675 completed questionnaires was made. Nausea and vomiting in pregnancy was
Construction of questionnaires is not as easy as it first may seem. There are several issues to consider. This to avoid problems later in the analysis of the results. This article aim at presenting a selection of possible methodology problems related to the construction and use of questionnaires.
Background: Firm recommendations about the way thiopurine drugs are introduced and the use of thiopurine methyltransferase (TPMT) and metabolite measurements during treatment in inflammatory bowel disease (IBD) are lacking. Aim: To evaluate pharmacokinetics and tolerance after initiation of thiopurine treatment with a fixed dosing schedule in patients with IBD. Patients: 60 consecutive patients wi
Enterohemorrhagic Escherichia coli produce an attaching and effacing lesion upon adhering to the intestinal epithelium. Bacterial factors involved in this histopathology include the intimin adhesin and E. coli secreted proteins (Esps) A and B. In this study we investigated the serum antibody responses to recombinant E. coli O157:H7 intimin, EspA, and EspB by immuno-blotting. Canadian patients with
TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) has a potency to induce decreased fertility and structural reproductive anomalies in male and female mammals. While the activity profile of sex steroid hormone production distinctly differs in developing males and females, we wanted to analyze sex-specific effects of TCDD introduced in utero and via lactation on gonadal steroidogenesis and gonadotropin le

An extended table of Shuurman's bounds on the state complexity of short binary linear codes is presented. Some new lower and upper bounds are obtained. Most of the newly found codes are based on the so-called double zero-tail termination (DZT) construction
The paper describes the influence exercised by professor Kjell Granström in the teaching of psychology. Among pedagogical inventions inspired by Granström are to be found training in small group obesrvation in a laboratory format the use of group diaries, training in consultation. The importance of a close connection between research and teaching is discussed.

When ferrochromium is produced at Vargon Alloys AB (Vargon, Sweden), an offgas dust is generated as a byproduct. A leachate that contains hexavalent chromium (Cr6+) is formed when rainwater percolates through the dust deposit. In this study, Cr6+ in the leachate was reduced to trivalent chromium (Cr3+) by biological treatment in a biofilm process operated under anaerobic conditions. The reactor vo
Solitary bees and bumblebees have declined substantially throughout western Europe during the last 100 years. Many species are important pollinators and are associated with particular plant species and habitats. In this study we report the highest number of bee species found at one locality in Sweden (Table 2). In total 87 species of wild bees (74 species of solitary bees and 13 species of bumble
