OBJECTIVE: To compare the reliability of quantitative measurement of minimum hip joint space with a qualitative global assessment of radiological features for estimating the prevalence of primary osteoarthritis (OA) of the hip in colon radiographs.METHODS: All colon radiographs from patients aged 35 or older, taken at three different radiographic departments in Iceland during the years 1990-96, we

Popular Abstract in Swedish Denna avhandling beskriver studier av de mekanismer varmed bakterien Streptococcus pyogenes undviker komplementdeposition och fagocytos.Phagocytosis of Streptococcus pyogenes is complement dependent. However, the cell wall-associated M protein, which exists in >100 different serotypes (M types), enables the bacteria to evade phagocytosis. To analyze the mechanisms by which M protein confers this ability we used, as model systems, two representative M proteins, the M22 and M5 proteins, which have properties typical for many M prote

This paper describes how attribute grammars can be used to integrate program visualization in language-based environments and how program visualizations can be specified and generated from grammars. It is discussed how a general solution for a simple grammar can be reused in grammars for other specific languages. As an example we show how diagram generation for a very simple state transition langu

The interaction between the nonionic surfactant C12EO6 and the poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) triblock copolymer EO20PO68EO20 (P123) has been investigated by means of isothermal titration and differential scanning calorimetry (DSC) as well as static and dynamic light scattering (SLS and DLS). P123 self-assembles in water into spherical micelles at ambient temperatu

Popular Abstract in Swedish Avhandlingen utgörs av en kritisk edition av Johannes Annorelius? latinska brev till brodern Julius (G3, Uppsala universitetsbibliotek). I början av 1700-talet lämnade Johannes Annorelius Uppsala och blev katolik och kapucinmunk i Flandern. Från klostret skrev han många, långa brev på franska och latin till sin lutherske bror i Sverige. I breven förklarar han varför hanThis book presents a critical edition of the Latin letters in ms. G3 (Uppsala University Library) from Johannes Annorelius to his brother. Johannes Annorelius left Sweden as a young student in the beginning of the 18th century and settled down in Flanders, where he converted to the Catholic faith and became a Capuchin friar. In the Capuchin friary Annorelius wrote several extensive letters in Fren

BACKGROUND: Information on cancer prevalence is of major importance for health planning and resource allocation. However, systematic information on cancer prevalence is largely unavailable. MATERIALS AND METHODS: Thirty-eight population-based cancer registries from 17 European countries, participating in EUROPREVAL, provided data on almost 3 million cancer patients diagnosed from 1970 to 1992. Sta

The objective is to investigate whether a silicon diode detector designed to measure the radiation levels in medical diagnostics also could be used as a dosemeter for people involved in the handling of a nuclear or radiological accident.

Popular Abstract in Swedish Chefskap och ledarskap hos sjuksköterskor i högre chefsbefattningar inom hälso- och sjukvården. I dagens hälso- och sjukvård har sjuksköterskor i chefsposition en förändrad och utökad roll, bland annat till följd av decentraliserade organisationer och utökade ansvarsområden. Utvecklingen av omvårdnaden kommer till en del att vara beroende av chefernas förmåga och skickThe aim of this thesis was to illuminate the management and leadership of nurse managers within Swedish health care organizations and to recognize influencing factors of importance for the nurse managers in exercising and developing their management. The interviewees were all active in their positions at the time of the interviews. The nurse managers served at top management levels in either execu

CD1d-restricted natural killer T (NKT) cells can have multiple effects on an immune response, including the activation, regulation and attraction of innate immune cells, and modulation of adaptive immunity. Recent studies reveal that there are distinct subsets of NKT cells which selectively perform some of the functions attributed to CD1d-restricted cells, but the mechanisms underlying these funct

OBJECTIVE: To estimate the prevalence of spondyloarthritis and its subtypes. METHODS: The Swedish healthcare organisation comprises a system where all inpatient and outpatient care is registered by a personal identifier. For the calendar years 2003-7, all residents aged ≥15 years in the southernmost county of Sweden (1.2 million inhabitants) diagnosed by a physician with spondyloarthritis (ankylo

A well-developed spatial memory is important for many animals, but appears especially important for scatter-hoarding species. Consequently, the scatter-hoarding system provides an excellent paradigm in which to study the integrative aspects of memory use within an ecological and evolutionary framework. One of the main tenets of this paradigm is that selection for enhanced spatial memory for cache

The generation of mathematical models of biological processes, the simulation of these processes under different conditions, and the comparison and integration of multiple data sets are explicit goals of systems biology that require the knowledge of the absolute quantity of the system's components. To date, systematic estimates of cellular protein concentrations have been exceptionally scarce. Her

Decorin and biglycan are closely related abundant extracellular matrix proteoglycans that have been shown to bind to C1q. Given the overall structural similarities between C1q and mannose-binding lectin (MBL), the two key recognition molecules of the classical and the lectin complement pathways, respectively, we have examined functional consequences of the interaction of C1q and MBL with decorin a

The intestinal mucosa presents a huge surface area to the external environment and the intestinal immune system is continually exposed to a wide array of foreign antigens derived from resident intestinal microbiota as well as dietary constituents, including food proteins. In order to maintain intestinal homeostasis, the intestinal immune system relies on the ability to generate tolerogenic respons

In birds, molt duration is an important trait that can affect plumage functionality and, consequently, the fitness of individuals. However, knowledge about the factors that affect variation in molt speed is sparse, mostly because of the methodological difficulties of studying avian molt. We used a ptilochronology-based approach to estimate the rate at which tail feathers were produced during molt

The three Mn I lines at 17325, 17339, and 17349 angstrom are among the 25 strongest lines (log(gf) > 0.5) in the H band. They are all heavily broadened due to hyperfine structure, and the profiles of these lines have so far not been understood. Earlier studies of these lines even suggested that they were blended. In this work, the profiles of these three infrared (IR) lines have been studied theor
