Amplification at the long arm of chromosome 8 occurs in a large fraction of breast and prostate cancers. To clone the target genes for this amplification, we used suppression subtraction hybridization to identify overexpressed genes in the breast cancer cell line SK-Br-3, which harbors amplification at 8q (8q21 and 8q23-q24). A differentially expressed gene identified by SSH, the p40 subunit of eu
In this work, we featured an expression system that enables the production of sufficient quantities (~mg) of low molecular weight membrane protein of photosystem II, PsbH protein, for solid-state NMR as well as other biophysical studies. PsbH gene from cyanobacterium Synechocystis sp. PCC 6803 was cloned into a plasmid expression vector, which allowed expression of the PsbH protein as a glutathion
BACKGROUND: Pulmonary hypertension is a postoperative complication that may adversely affect the outcome of lung transplantation. The effect of nitric oxide (NO) inhalation on pulmonary hemodynamic indices after lung transplantation was studied and compared with findings in control pigs. METHODS: Varying concentrations of NO were inhaled by 5 pigs after left lung transplantation and right pneumone
Abstract in UndeterminedThe temporal non-determinism introduced by computing and communication in the form of delay and jitter can lead to significant performance degradation. To achieve good performance in systems with limited computer resources, e.g. embedded systems, the resource constraints of the implementation platform must be taken into account at design time. To facilitate this, software t
Salivary gland carcinomas demonstrate a wide diversity of histopathological types and biological behavior. The aim of this study was to analyze relative survival of patients with major salivary gland carcinomas with special reference to histopathology, gender and age. All new carcinomas of the major salivary glands reported to the National Swedish Cancer Registry 1960-1995 were searched for and th
We performed a physiological and morphological characterization of sensilla auricillica in male Eriocrania semipurpurella moths. Each auricillic sensillum contained three olfactory receptor neurons. Responding neurons (87 of 139) could be grouped into five physiological types. Type 1 responded to (R,Z)-6-nonen-2-ol and type 2 to its enantiomer (S,Z)-6-nonen-2-ol, both of which are pheromone compon
Covalent bonding is commonly described by Lewis's theory(1), with an electron pair shared between two atoms constituting one full bond. Beginning with the valence bond description(2) for the hydrogen molecule, quantum chemists have further explored the fundamental nature of the chemical bond for atoms throughout the periodic table, confirming that most molecules are indeed held together by one ele
BACKGROUND: Treatment with heparin has been reported to interfere with lipid metabolism by release of Lipoprotein Lipase (LPL) into the circulation. The purpose of the present study was to determine the effects on LPL activity by anticoagulants in combination with total parenteral nutrition (TPN) in the rat. In an earlier investigation we could show that TPN, per se, caused a three-fold increase o
Trends towards distributed power generation and the deregulation of energy markets are increasing the requirement for software tools that optimize power generation plant design and operation. In this context, this paper describes the GTPOM (thermo-economic optimization of whole gas turbine plant) European project, funded in part through the European Commissions 5th Framework Programme, focusing on
Abstract Time series analysis is a tool that is now commonly used when analysing the states of natural populations. This is a particularly complicated task for ungulates, since the data involved usually contain large observation errors and span short periods of time relative to the species’ life expectancies. Here we develop a method that expands on previous analyses, combining statistical state s
Background In addition to its glucose-lowering effect, metformin treatment has been suggested to improve lipidaemia in patients with type 2 diabetes. In contrast, in patients with type 1 diabetes (T1DM), information about the effect of metformin treatment on lipidaemia is limited. In this study, we report the effect of a 1-year treatment with metformin vs. placebo on plasma lipids in T1DM patients
To determine the epidemiology and outcome of children with Down syndrome (DS) diagnosed with acute leukaemia in the Nordic countries, data registered in the Nordic Society of Paediatric Haematology and Oncology (NOPHO) population-based leukaemia registry were analysed. Of 3494 children with acute leukaemia diagnosed between July 1984 and December 2001, 136 patients (3.9%) with DS were identified.
Differences in growth conditions during early life have been suggested to cause long-lasting effects on morphology and quality of adult birds. We experimentally investigated the effect of early growth conditions on the expression of sexual ornaments later in life in male ring-necked pheasants (Phasianus colchicus). We also investigated the effects on immune function, as it could be a functional li
The immunocompetence handicap hypothesis (ICHH) provides a functional explanation for how sexual ornaments can provide honest signals of male quality. A key aspect of this hypothesis is that testosterone (T) has a bimodal effect: a higher T level enhances the expression of ornaments (increasing mating success and, ultimately, fitness); however, at the same time, it suppresses immune function. Test
Examensarbetet är en dokumentation och undersökning av det existerande bruksområdet i Orrefors, Småland. Utgångspunkten för detta är att glasbruket lade ned sin produktion år 2013. Vidare utforskar detta projekt hur bruksområdets östra del kan vidareutvecklas för att hålla samma höga kvalitet i rumslighet som sin västra motsvarighet. Arbetet handlar också om att åter ta i anspråk tidigare brukslok
SpectraCure AB is a start-up company aiming at treating internal solid tumours such as prostate tumours with an innovative technology called ‘Interstitial Photodynamic Therapy’. This treatment requires the use of fibres to deliver the amount of light required to activate a drug injected to the patient which leads to the destruction of the tumours. This treatment is patient-based which means that t
The enactment of the Water Sustainability Act by the province of British Columbia, Canada, in 2016 signals a shift towards a more decentralized and localized approach to water governance in the province. In this context, this thesis explores the history of development in the socio- ecologically significant Fraser Basin and identifies that a unique and successful form of collective- action to addre
The triglyceride/ aqueous interface has an important role in many processes, e.g. lipase activity. Lipase is responsible for the degradation of triglycerides to smaller components, such as fatty acids. The enzyme attracts interest in industrial applications of the catalytic behavior it possesses, such as in food and pharmaceutical industries. Thus, understanding the interface which is controlling
Climate change has become one of the greatest concerns of the 21st century as its ramifications pose a major risk to all life on earth. However, not all individuals are aware of this risk and behavioral engagement to counteract the issue is often still lacking. This research examined the relationship between climate change risk perception and pro-environmental behavior. The aim of this cross-secti
