Background Both gastrectomy (GX) and ovariectomy (OVX) induce osteopenia in man and experimental animals. The present study addresses the question - can alendronate, estrogen or parathyroid hormone (PTH) be used to treat established GX- or OVX -evoked osteopenia? Methods Rats were GX-, OVX- or SHAM-operated 8 weeks before starting the treatment with drugs. Each group was then treated for 8 weeks

Popular Abstract in Swedish I denna avhandling studeras korruption och mutor som i första hand sociala och moraliska, snarare än ekonomiska, fenomen. Vilka beskrivningar och tolkningar ger svenska och danska biståndsarbetare av sina möten med vardaglig korruption? Hur fördömes, ursäktas eller rättfärdigas användandet av mutor? Går det att tala om en etikett för mutor, och hur ser denna i så fall uIn this dissertation, corruption and bribery are investigated as social and moral, rather than economic, phenomena. The analysis concentrates on the ways in which Swedish and Danish aid workers describe their experiences of everyday or 'petty' corruption. How do they view their encounters with everyday corruption in developing countries? In what ways are bribes condemned, excused, or justified? Wh

The dependence of charges accumulated on a quantum dot under an external voltage bias is studied. The charge is sensitive to the changes of number of filled levels and the number of conducting levels (channels). We clarify that there are two possible outcomes of applying a bias. (a) The number of conducting channels increases, but the number of filled levels decreases. (b) The number of filled lev

Dynamic changes in structure and morphology during the heating of iron powder to high temperatures have been studied in situ in an environmental scanning electron microscope (ESEM). The results have shown that the presence of lubricants leads to the formation of ferrite needles at about 500ºC. At higher temperatures, the recrystallization of alpha-iron, followed by the nucleation and growth of gam

Incorporating bowel into the urinary tract sets the stage for a potentially dangerous situation for the upper part of this tract. Obstruction, reflux and chronic bacteriuria may develop, all of which can all be detrimental. Most reports on renal function have used IVP and serum creatinine only, methods which are inadequate for proper assessment. Long-term follow-up of patients with ileal conduit d

The NOPEX experimental campaigns dealt with the land-surface-atmosphere exchange of momentum, heat, water and CO2 on local and regional scales. In this paper emphasis is put on the NOPEX experiences with respect to the spatial integration of fluxes of momentum, heat, humidity and CO2 over the mosaic of forest, agricultural land, lakes and mires that make up the southern part of the NOPEX area. It

The report contains abstracts of Master Theses (examensarbeten) made at the Department of Automatic Control, Lund, during the academic year 83/84. During this year 7 theses were made by 8 students. Most of the theses are written in Swedish with an English abstract.

Modulation of vascular smooth muscle cells from a contractile to a synthetic phenotype is thought to be important in the development of the atherosclerotic lesion. Such modulation depends on growth factors and is influenced by cell-cell and cell-matrix interactions. Whereas smooth muscle cells in the vessel wall are contractile, dispersed cells in culture rapidly modulate to synthetic phenotype, w

Tailbiting is an attractive method to terminate convolutional codes without reducing the code rate. Maximum-likelihood and exact a posteriori probability decoding of tailbiting codes implies, however, a large computational complexity. Therefore, suboptimal decoding methods are often used in practical coding schemes. It is shown that suboptimal decoding methods work better when the slope of the act

Popular Abstract in Swedish Nyligen genomförda undersökningar pekar på att mellan en och två procent av den vuxna befolkningen lider av hjärtsvikt (hjärtinsufficiens/hjärtinkompensation), en oförmåga hos hjärtat att med ett normalt fyllnadstryck förse kroppens olika organ med blod. Vanligtvis är orsaken primärt kardiell (utgående från hjärtat) där ischemisk hjärtsjukdom (kranskärlssjukdom) utgör dUse of beta-blockers and inhibitors of the renin angiotensin system (RAS) is established practice in the treatment of chronic heart failure (CHF). Clinical studies also suggest beneficial long-term effects of nitrates in CHF. In the Veterans Administration Heart Failure Trial (V-HeFT) I, the combined use of a nitrate and hydralazine reduced the mortality rate. However, it is not possible to determ

The potential of algal–bacterial microcosms was studied for the biodegradation of salicylate, phenol and phenanthrene. The isolation and characterization of aerobic bacterial strains capable of mineralizing each pollutant were first conducted. Ralstonia basilensis was isolated for salicylate degradation, Acinetobacter haemolyticus for phenol and Pseudomonas migulae and Sphingomonas yanoikuyae for

S-phase fraction (SPF), estimated in the flow cytometric DNA histogram, is a prognostic factor in breast cancer. There are, however, some inherent difficulties in the estimation of SPF, such as the influence of debris, aggregates, and normal cells. Most of the available SPF calculation principles try to consider these difficulties, but so far no consensus has been reached with regard to which prin

Glycoprotein gp-340 aggregates bacteria in saliva as part of innate defence at mucosal surfaces. We have detected size- and glycoforms of gp-340 between human saliva samples (n=7) and lung gp-340 from a proteinosis patient using antibodies and lectins in Western blots and ELISA measurements. Western blots of saliva samples, and of gp-340 purified, from the seven donors using a gp-340 specific anti
