The Paleocene-Eocene Thermal Maximum (PETM, ca. 56 Ma) is marked by a negative carbon isotope excursion (CIE) and increased global temperatures. The CIE is thought to result from the release of 13C-depleted carbon, although the source(s) of carbon and triggers for its release, its rate of release, and the mechanisms by which the Earth system recovered are all debated. Many of the proposed mechanis
The repeatability of the composition of pheromone emitted by individual female moths (Yponomeuta) was determined by gas Chromatographic analysis. An improved technique for repeated collections of airborne volatiles from the same moth was developed. The procedure did not harm the females and allowed precise quantification of 0.05 ng of pheromone components in 30-min collections. Individual females
The spectrum of mutations in the von Willebrand factor (VWF) gene in a Swedish type 1 von Willebrand disease (VWD) population was investigated. To gain more knowledge about the dynamics of VWD mutations, the data were analyzed from a population genetics perspective. The VWF gene was resequenced in 54 Swedish patients diagnosed with type 1 VWD. Fifty-five variable sites were located in exons, 10 in
The aim of this thesis was to study reproductive factors and genetic polymorphisms in relation to breast cancer risk and survival. An important component of this was to investigate the risk of specific breast cancer subgroups. The association between parity and breast cancer-specific survival was studied among 4,453 women diagnosed with breast cancer in Malmö, Sweden. It was found that: • Nullipar
It has recently been demonstrated that superparamagnetic iron oxide nanoparticles can be used as magnetomotive ultrasound contrast agents. A time-varying external magnetic field acts to move the particles and, thus, the nanoparticle-laden tissue. However, the difficulty of distinguishing this magnetomotive motion from undesired movement induced in regions without nanoparticles or other motion arti
Noroviruses (formerly Norwalk-like viruses) are a major cause of acute gastroenteritis worldwide and are associated with a significant number of nosocomial and food-borne outbreaks. In this study we show that the human secretor FUT2 gene, which codes for an alpha(1,2)-fucosyltransferase synthesizing the H-type 1 antigen in saliva and mucosa, is associated with susceptibility to norovirus infection
Lung surfactant (LS) is an extra-cellular lipid-protein system responsible for maintaining low surface tension in the lung and alveolar stability. Serum proteins cause dysfunction of this material, e.g. in adult respiratory distress syndrome (ARDS). BLES is a clinically used LS consisting of most of the lipids and associated proteins from bovine lung lavage. Aqueous phases of BLES at 30% and 70% h
von Willebrand factor (VWF) is a plasma protein that consists of a series of multimers of which the high-molecular-weight VWF multimers are the most potent in platelet adhesion and aggregation. The propeptide of the VWF (VWFpp) is known to be essential in the process of multimer assembly. Genetic studies were performed in a patient with a phenotype of von Willebrand disease (VWD) characterized by
Chemical risks of consumer goods are a rather new concern in society. These risks are usually based on sythetic chemicals and man-made, often imperceptible and potentially devastating. These risks are reliant on knowledge claims and experiences as basis for risk judgments since, for example, chemical properties, threshold values and exposure are part of defining the risk. But risks are also define
* The ectomycorrhizal fungus Laccaria bicolor has the largest genome of all fungi yet sequenced. The large genome size is partly a result of an expansion of gene family sizes. Among the largest gene families are protein kinases and RAS small guanosine triphosphatases (GTPases), which are key components of signal transduction pathways. * Comparative genomics and phylogenetic analyses were used to e
Aims: The aim of the study was to compare outcomes in unfractionated heparin (UFH) and bivalirudin-treated patients undergoing primary percutaneous coronary intervention (PPCI). Methods and results: This observational study contained 20,612 PPCI patients treated with either UFH monotherapy or bivalirudin with or without concomitant UFH. Patients with oral anticoagulant or glycoprotein IIb/IIIa inh
The way we use computers and mobile phones today requires large amounts of processing of data streams. Examples include digital signal processing for wireless transmission, audio and video coding for recording and watching videos, and noise reduction for the phone calls. These tasks can be performed by stream programs—computer programs that process streams of data. Stream programs can be composed
The key question answered by this study is whether it is possible to deliver a pharmacokinetic and pharmacodynamic duration of antidiuretic action long enough to ensure adequate antidiuresis with two daily administrations of desmopressin in patients with central diabetes insipidus (CDI). We studied the efficacy and safety of desmopressin i.v. in 13 CDI patients using two 3-way crossover designs, i
Summary Corporate acquisitions are negotiated during several occasions. If an agreement has not been met, the Swedish sale of goods act is applicable between the parties. The act indicates that the buyer has a duty to investigate the targeted company should the buyer invoke errors therein. An assessment of errors is based on the buyer’s reasonable expectations of the targeted company. The buyer caSammanfattning Överlåtelser av företag är betydelsefulla affärshändelser med förhandlingar i flera omgångar.

A small wind power plant connected to the grid has been modeled in Modelica/ Dymola and controlled using external controllers written in C++. The small wind power plant consists of three wind power units with a nominal power of 3kW and one grid connection interconnected with an internal DCgrid. All the controls needed for control and optimization for the operation of the individual parts in the pl
Creating Non-governmental Self-help groups (SHGs) has been a common thing in India since the early 1990’s. Studies show that the SHGs usually empower their members in different ways. The empirical material being used in this paper consists of one group discussion and twelve semi-structured interviews with members of five different SHGs being organized by a Non governmental organization (NGO) in Mu
Popular Abstract in Swedish I Sverige finns cirka 350 000 personer med diabetes. Motsvarande siffra i hela världen är cirka 350 miljoner människor och forskning talar för att antalet personer med diabetes kommer att öka dramatiskt under de närmsta decennierna. Den största ökningen sker i utvecklingsländer i urbana områden, till stor del beroende på livsstilsförändringar och förändringar i diet. UtSpecific aims: To examine whether the sociodemographic characteristics of patients with type 2 diabetes affect the odds of reaching the recommended treatment goals for HbA1c and blood lipids (study 1). To investigate whether the odds of coronary heart disease are higher in patients with diabetes living in deprived neighborhoods than in those living in wealthy neighborhoods (Study 2). To examine th
