Raloxifene reduces vertebral fracture risk in postmenopausal women with osteoporosis and established osteoporosis, but its efficacy in women with osteopenia has not been studied. The objective of this study was to evaluate the effect of raloxifene hydrochloride on the risk of vertebral fractures in postmenopausal women with osteopenia and to compare this effect with that in women with osteoporosis

Popular Abstract in Swedish I denna avhandlingen studeras solljusets effekter på organiskt material och bakterier i akvatiska ekosystem. Särskild inriktas arbetet på UV-B strålning då instrålning till jorden av detta kortvågiga UV-ljus troligen ökar p g a ett minskat ozonlager. Ozonlagersproblematiken är verifierad över både norra och södra halvklotet. Resultaten visar på att en betydande del av This thesis examines the role of sunlight, specifically ultraviolet-B radiation (280-320 nm), on dissolved organic matter (DOM) and bacteria in lakes. Field experiments in lakes with different humic contents and geographical locations have been performed. Photooxidation result in that part of DOM is oxidized to inorganic carbon (DIC), mainly CO2. The photooxidation rate can be of the same magnitu

Purpose: To determine if mutations in the retinal transcription factor gene NRL are associated with retinopathies other than autosomal dominant retinitis pigmentosa (adRP). Methods: Genomic DNA was isolated from blood samples obtained from 50 patients with Leber Congenital Amaurosis (LCA), 17 patients with the Enhanced S-Cone Syndrome (ESCS), and a patient with an atypical retinal degeneration tha

Photon-echo-relaxation measurements made on the 3H4-3P0 transition of 0.01 at. % Pr3+:YAG (where YAG represents yttrium aluminum garnet), 3H4-1D2 transition in 0.1 at. % Pr3+:YAlO3, and 7F0-5D0 transition in 0.25 at. % Eu3+:YAlO3 show that the photon-echo relaxation rate increases when the intensities of the excitation pulses are increased. Although a part of the relaxation-rate increase in Pr3+:Y

Second- and third-generation cephalosporins, notably cefotetan, are increasingly implicated in severe, sometimes fatal immunemediated hemolytic anemia. We describe a 26-year-old woman who developed severe hemolytic anemia 2 weeks after receiving a single prophylactic dose of cefotetan during cesarean delivery. The patient's DAT was weakly reactive for IgG and her serum reacted with cefotetan-coate

Gastrointestinal stromal tumors (GISTs), the most common mesenchymal tumors of the digestive tract, are believed to arise from the interstitial cells of Cajal. GISTs are characterized by mutations in the proto-oncogene KIT that lead to constitutive activation of its tyrosine kinase activity. The tyrosine kinase inhibitor STI571, active against the BCR-ABL fusion protein in chronic myeloid leukemia

Popular Abstract in Swedish Påverkan av faktor V Leiden-mutationen på risk för utveckling av neovaskulära komplikationer efter centralvenstrombos studerades. Hos patienter med mutationen var risken nästan tre gånger högre att utveckla neovaskulära komplikationer än hos patienter utan mutationen. Synnervssvullnad , som nyligen har presenterats som en indikator på god prognos vid centralvenstrombosThe influence of the factor V Leiden mutation on the development of neovascular complications in central retinal vein occlusion was studied. The presence of the mutation was found to enhance the risk of developing neovascular complications almost threefold compared to in patients without the mutation. Optic nerve head swelling, which recently has been presented as an indicator of good prognosis i

To investigate how the relation between the control time and the total amount of water varies with the water application rate at manual fire fighting operations, six different experimental fire test series were studied. In spite of being quite different, the experiments prove to give similar results. Plotting the total volume of water required against the application rate, gives a diagram in the s

A measurement of direct photons in p+p collisions at root s=200 GeV is presented. A photon excess above background from pi(0)->gamma+gamma, eta ->gamma+gamma and other decays is observed in the transverse momentum range 5.5 < p(T)< 7 GeV/c. The result is compared to a next-to-leading-order perturbative QCD calculation. Within errors, good agreement is found between the QCD calculation and the meas

This paper presents a decision theory which allows subjects to account for the uncertainties of their probability estimates. This is accomplished by modelling beliefs about states of nature by means of a class of probability measures. In order to represent uncertainties of those beliefs a measure of epistemic reliability is introduced. The suggested decision theory is evaluated in the light of emp

The goal of the study is to cast light on the psychological factors behind the participation in nature conservation projects aiming to promote biodiversity. Two projects, wetland restoration and forest preservation, are examined through the framework of the VBN (Value-Belief-Norm) theory. A survey was conducted among 120 farmers and 160 forest owners in southern Sweden. Results did not support the
