The structure, luminescence spectroscopy, and lifetime decay dynamics of Eu2O3 nanoparticles formed in MCM-41 have been investigated. Both X-ray diffraction and high-resolution transmission electron microscopic observations indicate that Eu2O3 nanoparticles of monoclinic structure are formed inside channels of MCM-41 by heating at 140 degreesC. However, heat treatment at 600 or 700 degreesC causes
Recombinant factor VIIa (rFVIIa) has been developed for treatment of bleeding in patients with hemophilia who have inhibitors against factor VIII (FVIII) or FIX, and has been found to induce hemostasis during major orthopedic surgery. The use of rFVIIa treatment for hemophilia is a new concept and is based on the low-affinity binding of FVIIa to the surface of thrombin-activated platelets. Adminis
Popular Abstract in Swedish Metoder behövs att noggrant mäta rörelse och slitage av ledpannan efter operation med konstgjord höftled. EBRA-metoden (Ein Bild Röntgen Analyse) presenterades nyligen som en datoriserad metod att mäta rörelse av ledpannan. I denna studie utvärderades ett antal standardmetoder att mäta rörelse av ledpannan och jämfördes med radiostereometri (RSA), en metod som visats haMethods are needed for accurate measurement of acetabular cup migration and wear after hip replacement. The EBRA (Ein Bild Röntgen Analyse) method was recently introduced as a computerized method for radiographic assessment of acetabular cup migration. In this study, various standard methods for measuring migration were evaluated and compared to radiostereometry (RSA), which has proved to be high
Objectives To calculate the normal range for the fetal middle cerebral artery (MCA)/uterine artery pulsatility index (PI) ratio in the third trimester of pregnancy and to assess its value, compared with that of the MCA/umbilical artery PI ratio, in predicting an unfavorable outcome of pregnancies complicated by pre-eclampsia. Methods Doppler blood flow velocimetry of the uterine and umbilical arte
The aim of this work is practical. We show that the parameters of the widely used operational model of pharmacological agonism are difficult to estimate from single dose-response curves. The parameters can be estimated using pairs of dose-response curves (usually treatment and control) sharing some parameters. Confidence bands for the estimators are developed. In the case of multiple dose-response
Aim. To explore patients' evaluation of a specialized diabetes clinic for management of women with gestational diabetes born in Sweden and the Middle East and its contribution to a decreased level of stress and improved coping capability to promote health in patients receiving care. Background. No studies comparing patients' perceptions of healthcare in women of different origin with gestational
Phosphonic acid (H3PO3) is a candidate as an anchor group that can be used to bind a wide range of molecules to TiO2 surfaces, with practical applications for example in dye-sensitized solar cells. Adsorption geometries and energies of H3PO3 on the TiO2 anatase (1 0 1) surface have therefore been investigated using quantum-chemical periodic hybrid ab initio Hartree Fock density functional theory c
The Black-headed Gull Larus ridibundus is a monomorphic species with little size variation over its wide distribution range. This is in agreement with the wide dispersal of young birds and change of breeding sites of adults between years, which probably means an almost panmictic dispersal of genes. In 1965 I measured and weighed 319 eggs collected at Sjolunda near Malmo, southern Sweden. When I go
Study Design. Observational cohort study. Objective. To evaluate by MRI whether a vertebral fracture during childhood is a risk factor for degeneration of adjacent discs. Summary of Background Data. Several studies infer that trauma is a major cause of disc degeneration. Only 1 study has by magnetic resonance imaging (MRI) evaluated disc degeneration in children with a former thoracic or lumbar ve
Serine protease inhibitors (Serpins) are involved in the pathogenesis of neurodegenerative dementia, including the two most common types, Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB). The pathological characteristics of AD include senile plaques, mainly composed of aggregated amyloid-beta peptide (Abeta1-42), but also serpins, and neurofibrillary tangles of hyperphosphorylated tau
This short essay on how the book is used in Dutch paintings of the 16th and 17th centuries stresses the ambiguities of its overt message and latent symbolism, more varied than mere erudition or inevitable mortality.
Giant cell reparative granuloma (GCRG) is an uncommon lesion most often affecting the jaw but also the small bones of the hands and feet. GCRG overlaps clinically and radiographically with other giant cell-rich tumors such as giant cell tumor of bone (GCTB) and aneurysmal bone cyst (ABC). In the only case of a cytogenetically investigated GCRG reported previously, a balanced translocation involvin
Flertalet nya läkemedel tas fram av universitet och undervisningssjukhus, ofta med betydande offentliga subsidier, för att därefter tas över av läkemedelsindustrin, vars främsta uppgift är att utföra de kliniska prövningarna. Det är viktigt nog, men betydligt mindre innovativt än vad industrin vill få oss att tro, skriver Anders Jeppsson i polemik mot ett tidigare inlägg av Pierre Lafolie.
The difference in length of breast feeding between women with a BRCA 1 mutation and their unaffected relatives was investigated. Fifty women belonging to a family with a known BRCA1 mutation had themselves undergone testing and each had given birth to at least one child. Women with BRCA1 mutation breast-fed their first infant for a significantly shorter period (P = 0.048) and the second and third
