Study I: Thirteen patients underwent a modified Ross operation in which the free-standing pulmonary autograft was supported externally by a Dacron vascular prosthetic jacket (DVPJ). The tailor-made DVPJ prevented dilatation of the neo-aortic root significantly following a median follow-up of 47 months compared to a cohort of l3 matched patients undergoing conventional Ross operation. Study II: A

The cardiovascular risk for users of use of Swedish snus/American snuff (moist tobacco) has been debated for a long time. The present study was designed to examine the effects of water- or lipid-soluble (DMSO-soluble) snus and nicotine, the most important substance in tobacco, on the expression of vasocontractile G-protein coupled receptors (GPCR), such as endothelin ETB, serotonin 5-HT1B, and thr

It is known that warm and humid environment reduces human physical performance. The present study examined whether the use of an ice-vest in such conditions can improve cycling performance. Seven participants cycled with consecutive, non-stop, 10-minute cycles of nine minutes at 60% of their (V) over dot O-2 max punctuated by a one-minute sprint at 80% (V) over dot O-2 max. The cycling protocol wa

The polymeric immunoglobulin receptor (pIgR) is a key component of the mucosal immune system that mediates epithelial transcytosis of immunoglobulins. High pIgR expression has been reported to correlate with a less aggressive tumour phenotype and an improved prognosis in several human cancer types. Here, we examined the expression and prognostic significance of pIgR in pancreatic and periampullary

Background and purpose Spontaneous osteonecrosis of the knee (SPONK) is a painful lesion in the elderly, frequently leading to osteoarthritis and subsequent knee surgery. We evaluated the natural course and long-term consequences of SPONK in terms of need for major knee surgery. Methods Between 1982 and 1988, 40 consecutive patients were diagnosed with SPONK. The short-term outcome has been report

Popular Abstract in Swedish Med stigande ålder försvagas våra vävnader. Om bukväggen i ljumsken blir för svag, så kan bukinnehållet pressas ut genom svagheten. Detta kallas för ljumskbråck. Sjukdomen är mycket vanligare hos män och drabbar alla åldrar. Ju äldre man är, desto vanligare att man drabbas av ett ljumskbråck. Man upplever då, framför allt vid ansträngning, en oftast rörlig och ibland smBackground: In the nineties, the patients with inguinal hernias were exposed to several newly developed repair techniques using alloplastic mesh prosthesis. Although the scientific knowledge was limited, the new techniques were rapidly introduced due to surgical enthusiasm, but also by an eagerness to reduce the recurrence rate and to shorten the time to recovery. When the first study of this thes

In the present study we investigate the fate of citalopram (CIT) at neutral pH using advanced water treatment technologies that include O(3), ClO(2) oxidation, UV irradiation and Fenton oxidation. The ozonation resulted in 80% reduction after 30min treatment. Oxidation with ClO(2) removed>90% CIT at a dosage of 0.1mgL(-1). During UV irradiation 85% reduction was achieved after 5min, while Fenton w

Popular Abstract in Swedish Vad arbetar en analytisk kemist med? Exempel på kemiska analyser är att en idrottsman ska dopingtestas eller att eventuella föroreningar i vattnet från en bäck ska bestämmas. Den analytiska kemistens problemställning är vanligtvis att identifiera (kvalitativ analys) och mäta upp (kvantitativ analys) innehållet i ett prov. Ofta är de intressanta ämneshalterna mycket lågaCapillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.

The objective of this work was to examine the atazanavir-bilirubin relationship using a population-based approach and to assess the possible application of bilirubin as a readily available marker of atazanavir exposure. A model of atazanavir exposure and its concentration-dependent effect on bilirubin levels was developed based on 200 atazanavir and 361 bilirubin samples from 82 patients receiving

Miljontals människor världen över arbetar som gatuförsäljare, utom räckhåll för lagen. Eftersom verksamheten ses som illegal lever försäljarna under ett ständigt hot om att avhysas och att få sina varor konfiskerad. Olika strategier för formalisering, det vill säga stegvis legalisering, förespråkas och tillämpas, av såväl internationella utvecklingsorganisationer som regeringar, för att stärka gatMillions of people worldwide work outside the law as street vendors in order to earn a living. However, they often work in fear of police evictions and confiscations since their work is in many places considered illegal. In this context, formalization (steps towards legalization) is often portrayed as a model for empowerment that allows poor street vendors to improve their well-being. Formalizatio

How did human symbolic behavior evolve? Dating up to about 100,000 y ago, the engraved ochre and ostrich eggshell fragments from the South African Blombos Cave and Diepkloof Rock Shelter provide a unique window into presumed early symbolic traditions of Homo sapiens and how they evolved over a period of more than 30,000 y. Using the engravings as stimuli, we report five experiments which suggest t

Sammanfattning I Sverige råder fri bevisprövning med fri bevisvärdering. Det innebär att inga formella regler uppställs för hur ett bevis ska värderas eller vilka metoder som ska tillämpas av domstolen vid bevisvärderingen. Således är det teoretiskt möjligt att vid en ord mot ord situation finna det ställt utom rimligt tvivel att den tilltalade gjort som åklagaren gör gällande. Trots detta är det Summary In Sweden there is a free sifting of evidence with a free evaluation of evidence. This means that no formal rules are imposed on how evidence should be valued or the methods to be applied by the court at the evaluation of evidence. It is theoretically possible to find it beyond reasonable doubt that the accused made as the prosecutor alleges in a situation where one word stands against ano

This dissertation is a study in empirical macroeconomic history. The first two papers concern themselves with the functional distribution of income. The third paper is an examination of global real interest rates, and the final paper examines city growth in Sweden over the last two hundred years. While this thesis is not about secular stagnation per se, every articles is related in one way or the

Software systems are becoming increasingly ubiquitous and can be found in devices we use every day from mobile phones to cars. As our reliance on software-based systems increases, our tolerance with software that is ill-fitted to our needs decreases. We expect these devices to function whenever and however we need them to. However, developing these (often) large and complex software systems to mee

Molecularly imprinted polymers (MIPs) targeting quercetin were prepared from 4-vinylpyridine and ethylene dimethacrylate (EDMA) under various solvent systems with the aim to form MIPs with high recognition for the quercetin molecule in aqueous systems at high temperature. A MIP prepared from the three-component solvent mixture of THF/H2O/MeOH showed potential in its application for the determinati

Den offentliga sektorn är en stor aktör på många olika marknader. Offentliga inköp görs varje år för betydande summor i Sverige. Det offentliga upphandlingsförfarandet styr dessa inköp och regleras framförallt i LOU. Ett upphandlingsförfarande bygger på tanken att låta leverantörer konkurrera om offentliga kontrakt på ett öppet, likvärdigt och konkurrensneutralt sätt. De svenska upphandlingsbestämThe public sector is a major operator on numerous different markets. In Sweden public purchases are made for great amounts every year. The public procurement procedure is governing these purchases and is mainly regulated in LOU. A procurement procedure is based on the idea to let contractors compete for public contracts in an open, equal and competitively neutral way. The Swedish public procuremen
