Osteoprotegerin (OPG), a secreted member of the tumor necrosis factor receptor family, is a potent inhibitor of osteoclast activation and differentiation. In animal models OPG prevents bone loss, and in humans bone resorption can be reduced by injections of OPG. OPG may also play a role in cardiovascular disease since mice lacking the OPG gene display arterial calcification. In a screening effort
The new genus Masionhalea is segregated from Cetraria s. lat. on the basis of anatomy, morphology, ecology and chemistry. Its only species, M. richardsonii (Hook. in Richardson) Kärnef. is described and illustrated and a distribution map is provided.

We present here numerical simulations of surface solar convection which cover a box of 30 x 30 x 3.2 Mm(3) with a resolution of 315 x 315 x 82, which is used to investigate the dynamics of scales larger than granulation. No structure resembling supergranulation is present; possibly higher Reynolds numbers (i.e. higher numerical resolution), or magnetic fields, or greater depth are necessary. The r
Young vertebrates have limited capacity to synthesize antibodies and are dependent on the protection of maternally transmitted antibodies for humoral disease resistance early in life. However, mothers may enhance fitness by priming their offspring's immune systems to elevate disease resistance. Transgenerational induced defences have been documented in plants and invertebrates, but maternal primin
Medical students at a Swedish university were satisfied with their choice of future profession and they felt that the studies were stimulating. However, they experienced their student role as unclear, and that there was a lack of feedback from the teachers. The medical students showed a higher level of stress in comparison with non-medical students. The women had more stress and mental symptoms th
A previously healthy 3-month-old girl presented with symptoms of meningitis, diarrhoea, vomiting and fever. Green monkey kidney (GMK) cells inoculated with cerebrospinal fluid (CSF) revealed reovirus-like particles by electron microscopy. RNA-gel electrophoresis, immunofluorescence and virus neutralization identified the pathogen isolated from CSF as reovirus type 1. Antibody determination by immu
We prove that smooth solutions of the Degasperis-Procesi equation have infinite propagation speed: they loose instantly the property of having compact support.
A new idea for generation of quadrature signals on chip is presented. The topology is based on a passive RC polyphase filter, where the resistive parts are made active by using inverters. The active filter combines quadrature generation, isolation, and gain without losing quadrature performance compared to a regular RC polyphase filter. The filter technique is demonstrated in a 10 GHz front-end ap
Aims: Life expectancy in Sweden is among the highest in the world, and the province of Halland has the highest life expectancy in Sweden today. In an earlier paper the authors reported that life expectancy in the province of Halland in the south-west of the country was approx. 3.5 years above the national average between 1911 and 1950. The aim of this study was to explore the influence of differen
Forestry in Sweden suffers from browsing damage caused by large herbivores, mainly moose (Alces alces) and roe deer (Capreolus capreolus). Silviculture affects the availability of forage for these animals, and thus the browsing pressure. A step towards modeling the response of trees or to predict browsing damage is to gain more knowledge on the availability of food in forest stands. Individual gap
Popular Abstract in Swedish Denna avhandling är ett resultat av ett doktorandprojekt vid Kvartärgeologiska avdelningen, Lunds Universitet. Syftet med avhandlingen har varit att utröna huruvida bildningen av kalktuff i Sverige har varit beroende av klimatet samt under vilka tider och i vilken närmiljö tuffen bildats. I samband med under-sökningen har ett stort antal landsnäckor påträffats och analyAlthough deposition of freshwater calcium carbonates, tufa, has occurred in large areas with carbonate soil or bedrock in Sweden, no tufa formation has been observed in Sweden. To better understand the factors controlling tufa formation in southern Sweden, bio- and lithostratigraphical studies were carried out on (paludal) calcareous tufa deposits in the province of Skåne. The biostratigraphical m
