Popular Abstract in Swedish Det råder delade meningar om hur man bäst tar hand om patienter med lindrig primär hyperparatyreoidism (PHPT), dvs. överfunktion i en eller flera av de fyra bisköldkörtlarna med endast lätt förhöjning av kalciumnivån i blodet. Det finns de som förordar operation, medan andra anser att det inte behövs någon behandling så länge sjukdomen inte förvärras. Syftet med det aktThere is an ongoing controversy regarding how to take care of patients with mild primary hyperparathyroidism (PHPT). Some recommend surgical treatment at diagnosis, others just follow-up as long as there is no evidence of disease progression. The aim of this thesis was to evaluate cardiac and skeletal risk factors related to the duration of mild PHPT. Fifty patients with mild PHPT were randomized

When formulating a policy related to food in a heterogeneous context within a nation or between nations, oppositional positions are more or less explicit, but always have to be overcome. It is interesting to note, though, that such elements as culture and religion have seldom been the focus in discussions about methods of decision-making in food policy. To handle discrepancies between oppositional

Linear-transmitters based on combined analog locked loop universal modulator (CALLUM) architectures are attractive, as they promise both high efficiency and high linearity. To date, it has not been possible to analyze a CALLUM transmitter as a linear feedback network due to the nonlinear nature of the control equations governing it. The main purpose of this paper has been the derivation of a linea

There is no consensus on the treatment of congenital diaphragmatic hernia (CDH), and practice seems to vary between centres. The main purpose of the present study was to survey current practice in Scandinavia. Thirteen paediatric surgical centres serving a population of about 22 million were invited, and all participated. One questionnaire was completed at each centre. The questionnaire evaluated

We derive a partition function for the Lund fragmentation model and compare it with that of a classical gas. For a fixed rapidity “volume” this partition function corresponds to a multiplicity distribution which is very close to a binomial distribution. We compare our results with the multiplicity distributions obtained from the JETSET Monte Carlo for several scenarios. Firstly, for the fragmentat

Adsorption chromatography in expanded beds is a widely used technology for direct capture of target proteins from fermentation broths. However, in many cases this method cannot be applied as a result of the strong tendency of cells or cell debris to interact with the adsorbent beads. To prevent contamination of the expanded bed with the biomass, STREAMLINE DEAE, anion exchanger designed for expand

Albeit there is a general consensus that urban design in the twentieth century failed in relation to space use, systematic research on this aspect has been very limited or at most inadequate in the developing countries. This study focuses on the above failure of urban design in this century with specific reference to the developing countries through an analysis of Dar es Salaam city centre, Tanzan

Electronic and atomic structure of hexagonal boron nitride (h-BN) on lattice-mismatched transition metal surfaces has been studied systematically by X-ray absorption and photoelectron spectroscopy and diffraction. The strength of interfacial chemical interaction between h-BN and the substrates is rising in the row Pt(111)-Ir(111)-Rh(111)-Ru(0001). This rise directly correlates with a growing corru

Blood coagulation factor V (FV) is a 330 kDa plasma glycoprotein. Activated FV (FVa) is a non-enzymatic cofactor to activated Factor X in the activation of prothrombin that occurs during coagulation. To investigate the molecular mechanisms of the quantitative FV deficiency associated with the FV R2 haplotype (a common genetic variant in several populations), four missense mutations identified in

Popular Abstract in Swedish Arbetare i gummiindustrin utsätts för ett stort antal kemikalier med hög giftighet. Tidigare forskning har visat att kemikalierna innebär en fara för hälsan. Gummiarbetarna har tidigare haft en ökad risk att drabbas av olika sjukdomar, t.ex. cancer, hjärtkärlsjukdomar och luftvägsbesvär, jämfört med allmänbefolkningen. Däremot vet man inte exakt vilka ämnen som är farliWorkers in the rubber industry have an increased risk of several diseases, such as airway disease, cancer and probably cardiovascular disease. The exposure is very complex; carbon disulfide (CS2) and polycyclic aromatic hydrocarbons (PAHs) being two of the contaminants. The general aim of this thesis was to find exposure-response relationships usable for risk assessments in the rubber industry. U

In this study, we present a way of controlling the formation of the two types of zeaxanthin aggregates in hydrated ethanol: J-zeaxanthin (head-to-tail aggregate, characteristic absorption band at 530 nm) and H-zeaxanthin (card-pack aggregate, characteristic absorption band at 400 run). To control whether J- or H-zeaxanthin is formed, three parameters are important: (1) pH, that is, the ability to
