Prevalence of Helicobacter pylori vacA and cagA genotypes in Ethiopian dyspeptic patients
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/

Magnetic field effects on optical and transport properties in InAs/GaAs quantum dots
A photoluminescence study of self-assembled InAs/GaAs quantum dots under the influence of magnetic fields perpendicular and parallel to the dot layer is presented. At low temperatures, the magnetic field perpendicular to the dot layer alters the in-plane transport properties due to localization of carriers in wetting layer (WL) potential fluctuations. Decreased transport in the WL results in a red
Low salivary IgA activity to cell-surface antigens of mutans streptococci related to HLA-DRB1*04
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

Satisfaction with Daily Occupations: a tool for client evaluation in mental health care
Research findings suggest that in order to clarify the relationship between occupation and health, occupation needs to be framed in several different ways. One facet of occupation is satisfaction with daily occupations, assessed using the Satisfaction with Daily Occupations (SDO) instrument. The purpose was to investigate some of the SDO's psychometric properties when applied on people with persis
Alternative use of chromatic and achromatic cues in a hawkmoth
The diurnal hummingbird hawkmoth Macroglossum stellatarum can learn the achromatic (intensity-related) and the chromatic (wavelength-related) aspect of a spectral colour. Free-flying moths learn to discriminate two colours differing in the chromatic aspect of colour fast and with high precision. In contrast, they learn the discrimination of two stimuli differing in the achromatic aspect more slowl
Localized Surface Plasmon Resonance Sensing of Lipid-Membrane-Mediated Biorecognition Events
Supported phospholipid bilayers (SPBs) have emerged as important model systems for studies of the natural cell membrane and its components, which are essential for the integrity and function of cells in all living organisms, and also constitute common targets for therapeutic drugs and in disease diagnosis. However, the preferential occurrence of spontaneous SPB formation on silicon-based substrate
Quality indicators for woodwind reed material
For the generation of sound, some woodwind musical instruments, e.g. oboe, bassoon, clarinet and saxophone, are provided with mouthpieces made from reeds. These reeds are the culms of Arundo donax, a tall, cane-like perennial grass. A general problem is that the material is of varying quality, yet externally differences cannot be observed. Hence, large proportions of the prepared reeds are unusabl
Suppression of serum TSH by Graves' Ig: evidence for a functional pituitary TSH receptor
Antithyroid treatment for Graves' hyperthyroidism restores euthyroidism clinically within 1-2 months, but it is well known that TSH levels can remain suppressed for many months despite normal free T(4) and T(3) levels. This has been attributed to a delayed recovery of the pituitary-thyroid axis. However, we recently showed that the pituitary contains a TSH receptor through which TSH secretion may
Using Virtual Reality for Participatory Design and Brain Injury Rehabilitation
Popular Abstract in Swedish I denna avhandling har användbarheten av Virtual Reality (VR) utvecklats och undersökts för två användningsområden: participatorisk design av arbetsplatser och hjärnskaderehabilitering. Inom det första användningsområdet används VR tillsammans med fullskalemodellering, drama och demokratisk mötesteknik i en Visualiseringsverkstad. Denna arbetsmetod har utvecklats och tIn this thesis, the usability of Virtual Reality (VR) has been investigated and developed within two applications: participatory design of workplaces and brain injury rehabilitation. In the first application, VR is used in combination with full scale modelling, drama and democratic meetings in an Envisionment Workshop. This workshop has been developed and tested through several real workplace int

Low-impact exercise during pregnancy - a study of safety.
Background. Exercise is an important part of many women's lives. Women are often advised to refrain from physical exercise during pregnancy. The reason given is mainly safety, i.e. fear of maternal hyperthermia, which is known to be related to neural tube defects. However, exercise during pregnancy has not been shown to be related to hyperthermia. Objective. To study temperature and oxygen satura

Selection for sexual male characters and their effects on other fitness related traits in white leghorn chickens
The size and shape of the cockerel comb, ran be regarded as secondary sexual characters or sexual ornaments. Sexual characters are assumed to be costly to express and the expression of a secondary sexual character is suggested to be favourably correlated with the bearer's condition or fitness. The aim of this study was to clarify the effects of selection for male sexual characters, the correlated
Delayed stigma receptivity in Collinsia heterophylla (Plantaginaceae): Genetic variation and adaptive significance in relation to pollen competition, delayed self-pollination and mating-system evolution
To increase our knowledge about mating-system evolution, we need to understand the relationship between specific floral traits and mating system. Species of Collinsia (Plantaginaceae) vary extensively in mating system; this variation is associated with variation in floral morphology and development and with the timing of self-pollination. Counterintuitively, large-flowered, more outcrossing specie
