Magnetic and related properties of rocks and products from oxidation of sulphide minerals have been investigated with magnetisation measurements (rocks and oxidation products), magnetic force microscopy (rocks), scanning electron microscopy (rocks and oxidation products), transmission electron microscopy (oxidation products), Mössbauer spectroscopy (oxidation products) and powder X-ray diffraction
Objectives: Carotid stenosis is a crucial cause of ischemic stroke. Recent studies suggest that one of the most important effects of lipid-lowering statins is to stabilize vulnerable plaques. However, it remains to be determined if this effect is secondary to the lowering of plasma cholesterol levels or due to a direct effect of statins on plaques stability. Design and main outcome measures: In th
To date, only 16 cytogenetically abnormal hemangiopericytomas (HP) have been reported. Despite this low number, some characteristic karyotypic features have already emerged: most HP are near-diploid and breakpoints in 12q13, 12q24, and 19q13 seem to be common, with t(12;19)(q13;q13) being a recurrent translocation. Here, we report the first case of a probably benign splenic HP with chromosomal abn
The present study is composed of a series of six independent yet related articles treating various aspects of international trade and economic growth. In Chapter two the effects of European Integration (EI) on long-run economic growth is studied. Contrary to earlier empirical results long-run effects of EI are identified. As a development Chapter three examines two potential channels linking EI to
The fast timing beta gamma gamma(t) method was applied to investigate the level lifetimes in Mg-30,Mg-31,Mg-32. Levels in Mg have been populated in beta and beta-delayed neutron emission of Na, at the ISOLDE facility. From the gamma gamma coincidences a number of new states have been identified and new level schemes were constructed for 30 31,32 Mg. The following preliminary half lives have been d
To examine the pathophysiology of the age-related rise in the plasma concentration of parathyroid hormone (PTH), we studied the relationships among plasma immunoreactive PTH (iPTH), parathyroid gland volume, parathyroid cell proliferation rate, renal function, and blood Ca2+ in male Fischer 344 rats aged 6-28 mo. Plasma iPTH increased 2.5-fold between 6 and 28 mo and correlated with parathyroid gl
HEATOX is the acronym for a European Union-funded project entitled Heat-Generated Food Toxicants: Identification, Characterization, and Risk Minimization. Acrylamide will be the main experimental focus, but identification of unknown toxicants in heated carbohydrate-rich foods will also be attempted. The project includes research on formation chemistry, food technology, analytical methods, hazard c
Recombinant adeno-associated virus serotype 2 (rAAV2) vector has been widely employed for gene therapy. Recent progress suggests that the new serotypes of AAV showed a better performance than did AAV2 in normal tissues. Here, we evaluate the potential role of human vascular endothelial growth factor (VEGF) gene transfer using rAAV vector pseudotyped with serotype I capsid proteins (rAAV1) in the t
The nitrate reductase activity (NRA) was measured during spring, early summer and late summer in three deciduous forests, where the tree layer was dominated by oak. The nitrate assimilation capacities of the compartments of the above-ground and below-ground biomass of the understory and of the leaves and roots of the tree layer were calculated as NRA per unit biomass and NRA per unit area. The NRA
The thesis analyzes the everyday life of women and men in a neighbourhood planned for low-income housing in the ourskirts of the capital San José in Costa Rica. The research uses an everyday life perspective and shows how gender organization leads to a division of labour and a use of space that differentiate between women and men's activities. There are space use patterns that reflect the existing
Raloxifene treatment has been shown to reduce the risk of vertebral fractures and breast cancer in postmenopausal women. The long-term economic implications of treatment with raloxifene have not yet been investigated. The aim of this study was to assess the cost-effectiveness of treating postmenopausal women in the UK with raloxifene. A previously developed computer simulation model was used to es
We studied the role of arachidonic acid metabolites, histamine, and 5-HT in airway responses to trimellitic anhydride (TMA) in actively sensitized guinea pigs. Sensitization was produced by two intradermal injections of free TMA (0.1 ml of 0.3% TMA in corn oil). After 21 to 28 days, guinea pigs were anesthetized and challenged with intratracheal instillation of 0.5% TMA conjugated to guinea pig se
Artikeln diskuterar händelser i och omkring Sövde i samband med det "Skånska upproret" 1180-81. I Sövde fanns från 1100-talet och fram till reformationen fanns en befäst huvudgård tillhörande ärkesätet i Lund. Spåren efter denna anläggning kom att undersökas år 1911 av pastor loci Oscar Blomstergren under överinseende av Otto Rydbeck, docent i nordisk konstarkeologi, Lund.
A series of bioassay experiments were performed from spring to autumn in a small dimictic lake (Deep Pond, Massachusetts) to examine the potential for bacterial growth limitation by organic carbon (glucose), inorganic nutrients (ammonium or phosphate), or both. The experiments demonstrated that phosphorus was the primary element limiting bacterial growth in Deep Pond during a large part of the sum
