Background/aims: Mutans streptococci are found in almost all individuals, though there are large differences in colonization levels between individuals. These differences are not readily explained, though several factors are believed to influence the colonization. One factor is the immune response to mutans streptococci, mainly provided by salivary immunoglobulin A (IgA). In a previous study, diff

Background and aims: The primary aim of the present study was to examine whether there is an association between blood pressure and the risk of subsequent cognitive decline in the oldest old. Various factors associated with blood pressure and cognitive function were considered. Methods: The study comprised 599 individuals of a population-based sample, 199 men (mean age at baseline 82.8 years, rang

This paper presents a strategy for closed-loop control of a multi-cylinder turbocharged Homogeneous Charge Compression Ignition (HCCI) engine. A dual fuel port injection system allows control of combustion timing and load individually for each cylinder. The two fuels used are isooctane and n-heptane, which provides a wide range of autoignition properties. Cylinder pressure sensors provide feedbac

This article intends to present the Scandinavian legislation on female genital mutilation and explore the implications of the laws. Juxtaposing trends of plastic genital surgery in the West with claims that female circumcision may be a practice generally abandoned in Scandinavia, we highlight the double morality inherent in current public discussions. Finally, we pose the question: Is the legal pr

We present the red-listed plants and fungi that have been found in the central parts of the parish of Stenbrohult, southern Sweden. In the middle of the study areas Carl Linnaeus was born in 1707, and he spent his summers there until 1727. Of the 11 currently red-listed vascular plants (Gärdenfors 2000) that have been recorded since 1970 all occurred there also 300 years ago. Mosses, lichens and f

The main aim of this study was to validate a new technique, neural response telemetry (NRT), for measuring the electrically evoked compound action potential in adult cochlear implant users via their Nucleus CI24M implant. Thirty-eight adults were evaluated with a variety of measurement procedures with the NRT software. Electrically evoked compound action potentials were obtained in 31 of the 38 ad

Nine polypeptides of gastrointestinal origin were tested for their possible effect on vascular smooth muscle of the rat portal vein. The substances tested were bombesin, caerulein, glucagon, insulin, pentagastrin, secretin, somatostatin, substance P and vasoactive intestinal polypeptide (VIP). Cumulative dose-response relations of integrated mechanical activity (mean tension) were obtained with ma

A method for the in situ modification of hollow fiber membranes used as sampling units for microdialysis probes is presented. The method consists of adsorption-coating, high-molecular-weight poly(ethylene imine), PEI, onto membranes, already fitted on microdialysis probes. Modification of membranes was designed to specifically explore the so-called Andrade effects and thus enhance the interaction

Rapporten är utformad som en handbok för hjälp vid dimensionering och utformning av fogar i byggnaders ytterväggar. Boken innehåller en grundläggande problembeskrivning, genomgång av påverkande faktorer, materiallära, dimensionerings- och utformningsanvisningar samt tillämpningsexempel på lämpliga fogutformningar.

In this article the concept of trade or retail bindings with regard to the Swedish book market during the 18th and early 19th century is introduced and discussed. Binding techniques and materials as well as the cost of different kinds of Swedish trade bindings are shown. Special attention is given to the large production of almanacs, hymnbooks and ABC books destined for the peasantry. Complaints a

An integrative vector was constructed to allow expression of heterologous proteins into the adhB locus of Zymomonas mobilis. As a reporter gene, the ORF of a bright variant of green fluorescent protein from Aequorea victoria (GFPuv) was fused to the adhB strong promoter from Z. mobilis by using a two-step PCR strategy. Z. mobilis recombinant strains that were stably marked by precise gene replacem

Kinin B-1 receptors (B1R) are involved in many pathophysiological processes, and its expression is up-regulated in inflammatory pulmonary disease. Although bacteria can generate kinin peptides, the molecular signaling mechanisms regulating B1R during infection by intact pathogens is unknown. The serious opportunistic clinical isolate Burkholderia cenocepacia (B. cen.) belongs to the important B. c

A total of 300 gastric biopsy samples and 50 Helicobacter pylori isolates were collected from Ethiopian adult dyspeptic patients. The vacA and cagA genes were detected in 90 and 79% of biopsy specimens, respectively, and in 100 and 87% of clinical isolates, respectively. Both genes were detected in 84% of the gastric biopsy samples and in 87% of the clinical isolates. Among vacA genotypes, the s1/
