A randomised study in all cervical hip fractures Osteosynthesis with Hansson hook-pins versus AO-screws in 199 consecutive patients followed for two years

A consecutive series of patients with all types of cervical hip fracture (both undisplaced and displaced) were randomised to osteosynthesis with Hansson hook-pins (n = 98) or AO-screws (n = 101). Background parameters, fracture type and reduction of the fracture did not differ significantly between the groups. Fifty-seven percent of the patients were operated on within 6 h of admission to hospital

Archaeo-faunal aspects of bog finds from Hassleberga, southern Scania, Sweden

In recent years, small bogs at Hassleberga in southwestern Scania have been turned into crayfish ponds after the removal of the organic sediments. Bones and antlers were noticed in the excavated material and have been systematically collected. The finds include reindeer of both sexes and of different ages. Bones of wild horse, elk, arctic hare and arctic fox were also identified. Radiometric datin

Litteraturens makt

Har litteraturen makt att påverka människan och samhällsutvecklingen? Är det verkligen så att litteraturen har hjälpt till att avskaffa slaveriet i Amerikas sydstater eller att ge svenskarna religiös mötesfrihet? Kan den ha skadat äktenskapet som institution eller gett avgörande synpunkter inom barnuppfostran? Har den inspirerat FN i miljöfrågor, gett svenskarna dräpande argument i kärnkraftsdebat

Formation of Rhodium Carbonyl Cluster Thiolates with Concomitant H2 evolution

Reaction of [Rh6(CO)15(NCMe)] with p-thiocresol [(4-Me)C6H4SH] leads to the formation of [Rh2(CO)4(μ-SC6H4CH3)2] as the main product along with a small amount of [Rh6(CO)16]. An approximately 30-fold excess of the thiol is required in order to obtain a good yield of the thiolate-bridged dimer while reaction of [Rh4(CO)12] with an excess of p-thiocresol leads to an apparently clean conversion to th

Herpes simplex virus-2 may increase susceptibility of the sexual transmission of hepatitis C

OBJECTIVES: Antibodies against herpes simplex viruses-1 and -2, cytomegalovirus, and syphilis were determined in six heterosexual couples with strong indications of having sexually transmitted hepatitis C virus infection and in 17 other heterosexual couples in which one partner was hepatitis C virus viremic (source partner), but the other had remained hepatitis C virus uninfected (exposed partner)

The role of phosphodiesterase 3B in energy metabolism

Energy metabolism at the level of any particular tissue is tightly regulated by hormones, neurotransmitters and cytokines in order to maintain overall energy homeostasis. Any dysfunctions in energy metabolism may lead to more or less severe consequences, with obesity and type 2 diabetes being the most prevalent ones. Type 2 diabetes is characterized by defective insulin secretion (?-cell dysfuncti

Comprehensive ventilation/perfusion SPECT

Lung scintigraphy is the primary tool for diagnostics of pulmonary embolism. A perfusion study is often complemented by a ventilation study. Intermediate probability scans are frequent. Our goal was to develop a fast method for tomographic ventilation and perfusion scintigraphy to improve the diagnostic value of lung scintigraphy. METHODS: SPECT was performed with a dual-head gamma camera. Acquisi

Relativistic ab initio calculations of oscillator strengths and hyperfine structure constants in TlII

We present accurate calculations of oscillator strengths and hyperfine structure splitting for a set of transitions in Tl II, and discuss how they can be used in stellar atmosphere models of chemically peculiar stars. The results are in good agreement with recent experiments. The predicted uncertainty for oscillator strengths ranges from about 5 to 20% and in most cases less than 10% for hyperfine

On Behavioral Model Identification

This paper presents theory andalgorithms for system identification suitable for the framework of behavioral system theory. An algorithm basedon algebraic system theory and realization theory (Ho-Kalman realization) in a subspace model identification framework is presented. The novel approach taken consists of the formulation of input-output data as an impulse response model and the subsequent appl

Automated Calculation of Infarct Transmurality

The aim of this study was to develop all algorithm to automatically calculate infarct transmurality based oil a non dichotomous infarct classification, and to compare with manual delineation. Global transmurality as calculated by the computer algorithm were significantly smaller than the consensus delineation of three observers (p < 0.05). On a regional basis in 6 sectors of each slice the variabi

Review of Monica Weikert, I sjukdom och nöd. Offerkyrkoseden i Sverige från 1600-tal till 1800-tal. Göteborg 2004

Weikerts doktorsavhandling i historia definierar offerkyrkor som »en kyrka som av tradition har ansetts besitta en särskild kraft, vilket gjorde att en gåva – eller offer – där ansågs öka chansen till bönhörelse». De flesta finns i Skara och Växjö stift. Sin höjdpunkt nådde offrandet under slutet av 1600-talet och början av 1700-talet. Givarnas ursprung och attityderna vid visitationer har undersö

Multilinear forms of Hilbert type and some other distinguished forms

We give some new examples of bounded multilinear forms on the Hilbert spaces l(2) and L-2(0, infinity). We characterize those which are compact or Hilbert-Schmidt. In particular, we study m-linear forms (m >= 3) on l(2) which can be regarded as the multilinear analogue of the famous Hilbert matrix. We also determine the norm of the permanent on K-n, where K = R or C.

Where Does Metonymy Stop? Senses, Facets, and Active Zones

The purpose of this article is to propose a constrained lexical semantic definition of referential metonymy within a model of meaning as ontology and construal. Due to their various types of lexical-referential pairings, 3 types of construals that are frequently referred to as metonymy in the cognitive literature are distinguished as metonymization, facetization, and zone activation. Metonymizatio

Pathology findings and validation of gastric and esophageal cancer cases in a European cohort (EPIC/EUR-GAST)

Objective. Cardia, non-cardia and intestinal and diffuse subtypes of gastric cancer may have different trends and etiological factors. However, the available information is not always collected in population cancer registries, and heterogeneous criteria have been applied for the histopathological classification of tumors. We describe the pathological features of incident gastric and esophageal can
