Prevalence of hip osteoarthritis in Iceland

OBJECTIVE: To assess the prevalence of primary hip osteoarthritis (OA) in Iceland. To compare the prevalence of primary hip OA in Iceland with published rates of primary hip OA for related Scandinavian populations.METHODS: Roentgenographs were examined of 1530 Icelandic people 35 years or older (653 males, 877 females) subjected to colon radiography during the years 1990-1996. The radiographs exam

The biochemistry of the action of chymopapain in relief of sciatica

A study has been made of the mechanism of action of intradiscal injections of preparations of chymopapain in the treatment of sciatica. Such preparations were found to contain at least four distinct proteins, but enzymatically active chymopapain was the component mainly responsible for releasing glycosaminoglycan from cartilaginous tissue. Previous suggestions that an electrostatic interaction bet

Analysis of Computational Algorithms for Linear Multistep Methods

Linear multistep methods (LMMs) constitute a class of time-stepping methods for the solution of initial value ODEs; the most well-known methods of this class are the Adams methods (AMs) and the backward differentiation formulae (BDFs). For the fixed stepsize LMMs there exists an extensive error and stability analysis; in practical computations, however, one always uses a variable stepsize. It is w

Evidence-based evaluation of magnetic resonance imaging as a diagnostic tool in dementia workup

BACKGROUND: The diagnostic utility of magnetic resonance imaging in dementia workups has increased recently. The basic use is to exclude space-occupying processes in the brain. However, magnetic resonance imaging offers major opportunities for studying atrophy of specific brain areas. A great interest has been put in whether atrophy in the medial temporal lobe can serve as an early diagnostic mark

Fundamental limitations for DOA and polarization estimation with applications in array signal processing

Using a generic electromagnetic model based on the spherical vector harmonics, we provide the Cramer-Rao lower bound (CRB) for direction-on-arrival (DOA) and polarization estimation with arbitrary multiport antennas. By reciprocity, the receiving multiport antenna is characterized in terms of the transmission matrix from incident voltage waves to multipole coefficients of the outgoing spherical ve

Sexual dimorphism in lizard body shape: The roles of sexual selection and fecundity selection

Sexual dimorphism is widespread in lizards, with the most consistently dimorphic traits being head size (males have larger heads) and trunk length (the distance between the front and hind legs is greater in females). These dimorphisms have generally been interpreted as follows: (1) large heads in males evolve through male-male rivalry (sexual selection); and (2) larger interlimb lengths in females

I inledningsföredraget vid KZG-konferensen ”Europabilder der Kirchen in der Nachkriegszeit” i Höör i augusti 1998 definieras först ”motstånd” som olika i Tyskland, i de ockuperade länderna, i Storbritannien och i ”neutrala” länder, resp. från biskopsstolarna och ute i församlingarna. Olika definitioner av ”Europa” presenteras, där inte bara Rysslands, utan också Storbritanniens tillhörighet ifråga

Study of Particle Size Dependant Reactivity in an α-TCP Orthophosphate Cement

Calcium phosphates have been of great interest in the field of medicine for many decades due to their biocompatibility, hardening properties and diverse areas of application. In this study two different alpha phase tricalcium phosphate powders were produced of distinctly different particle size distributions. These two powders were then tested for reactivity and phase evolution. X-ray diffraction

Program Visualization using Reference Attributed Grammars

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

U46619 (a thromboxane A2 mimetic) induces airflow obstruction and airway plasma extravasation in the guinea pig: the role of histamine, cyclooxygenase metabolites, leukotrienes and PAF

The aim of the present study was to characterize the airway effects of U46619, a stable thromboxane A2 mimetic, instilled into the trachea of guinea pigs in vivo, and to investigate the role of different mediators in these effects. The airflow obstruction was evaluated by measurement of airway insufflation pressure (P1) and plasma extravasation by quantification of Evans Blue dye (EBD) in airways.

Menorrhagia and minor bleeding symptoms in women on oral anticoagulation.

Background Oral anticoagulation (OA) is a common treatment with a known risk of fatal or major bleeding, but also minor bleeding symptoms and menorrhagia can cause substantial discomfort and necessitate medical or surgical interventions. The extent of these side effects is however not previously reported. The objective of this study is to assess the frequency of minor bleeding symptoms and menorrh

Kön, makt och religion: En ohelig allians

Religion and religious ideologies interact with other power structures in society. Therefore religious factors should be considered in intersectional analyses,along with factors such as class, gender and ethnicity. The suggested tool of religious proximity is, as an example, applied to an analysis of women as religious leaders in the context of religious fundamentalism.

Essential role for CD103 in the T cell-mediated regulation of experimental colitis

The integrin CD103 is highly expressed at mucosal sites, but its role in mucosal immune regulation remains poorly understood. We have analyzed the functional role of CD103 in intestinal immune regulation using the T cell transfer model of colitis. Our results show no mandatory role for CD103 expression on T cells for either the development or CD4(+)CD25(+) regulatory T (T reg) cell-mediated contro
