Popular Abstract in Danish Genterapi er en attraktiv terapiform mod neurologiske lidelser som Parkinsons sygdom og epilepsi af flere grunde. Gener med en terapeutisk effekt kan introduceres lokalt ved præcise injektioner i det syge væv, hvor genproduktet kan frigives fra nerveceller i respons til aktivitet i det omgivende væv. Ved genterapi omgås den forhindring som blod-hjernebarrieren udgør, ligGene therapy is an attractive strategy for neurological disorders, such as Parkinson’s disease and epilepsy, for several reasons. Introduction of genes with a therapeutic potential can be achieved locally, by accurate injections in the compromised tissue, and release of a transgene therapeutic substance can be regulated by the surrounding host neural circuitry. The gene therapy approach circumvent

We have estimated the activation energy for aromatic oxidation by compound I in cytochrome P450 for a diverse set of 17 substrates using state-of-the-art density functional theory (B3LYP) with large basis sets. The activation energies vary from 60 to 87 kJ/mol. We then test if these results can be reproduced by computationally less demanding methods. The best methods (a B3LYP calculation of the ac

Background: With the rapid development of new genetic measurement methods, several types of genetic alterations can be quantified in a high-throughput manner. While the initial focus has been on investigating each data set separately, there is an increasing interest in studying the correlation structure between two or more data sets. Multivariate methods based on Canonical Correlation Analysis (CC

Popular Abstract in Swedish Diarré är ett vanligt symptom i befolkningen och det finns många differentialdiagnoser bakom orsaken till detta. En är inflammatorisk tarmsjukdom, något som har ökat kraftigt de senaste decennierna. Idag beräknar man att ca 1% av befolkningen har någon form av inflammatorisk tarmsjukdom och den klassas därför som en folksjukdom i Sverige. De inflammatoriska tarmsjukdomCollagenous colitis (CC) affects middle-aged women and results in chronic watery non-bloody diarrhoea. The incidence of CC has increased but has never been determined in southern Sweden. During the period 2001-2010 the mean annual incidence was stable; 5.4/105 (median age 71 years). The female: male ratio was 2.8:1, lower than in previous reports. The association between smoking and classic IBD is

Introduction: Knowledge of longitudinal progression in mild Alzheimer’s disease (AD) is required for the evaluation of disease-modifying therapies. Our aim was to observe the effects of long-term cholinesterase inhibitor (ChEI) therapy in mild AD patients in a routine clinical setting. Methods: This was a prospective, open-label, non-randomised, multicentre study of ChEI treatment (donepezil, riva

Despite its OECD membership and transformation from aid recipient into a major donor of official development assistance (ODA), Japan has long been criticized for pursuing commercial interests through its infrastructure-focused ODA, which has heavily relied on its own corporate private sector for implementation. Throughout the last two decades, institutional reforms have altered the structure and p

When selecting the least biased exposure surrogate, for example, the concentration of a biomarker in a urine sample, information on variability must be taken into consideration. We used mixed-effects models to estimate the variability and determinants of urinary cadmium (U-Cd) excretion using spot urine samples collected at six fixed times during 2 days about 1 week apart, from 24 healthy non-smok

Background: Arsenic is mono- (MMA) and dimethylated (DMA) in humans and the methylation pattern demonstrates large inter-individual differences. The fraction of urinary MMA is a marker for susceptibility to arsenic-related diseases. Objectives: The impact of polymorphisms in five methyltransferase genes on arsenic metabolism was evaluated in two populations, one in South America, one in southeast

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is today considered a novel specific vascular inflammatory biomarker. The general aim of this thesis was to study the role and impact of Lp-PLA2 as cardiovascular (CV) risk marker in an epidemiologic perspective. Specific aims were to explore the cross-sectional association of Lp-PLA2 with traditional CV risk factors, to asses the genetic influence

Popular Abstract in Swedish Hjärt- och kärlsjukdomar är idag den vanligaste dödsorsaken i stora delar av världen för både män och kvinnor. I Sverige är hjärtinfarkt den vanligaste dödsorsaken för kvinnor över 55 år och för män över 45 år. Det vill säga kvinnor drabbas cirka 10 år senare. Tidigare forskning har baserats i huvudsak på män varvid forskning på kvinnor med hjärt- och kärlsjukdomar har Background: Coronary heart disease (CHD) is the sleading cause of mortality in men and women in Western society. Few studies of CHD have been performed on women or with a focus on cardiac risk factors in women’s lives. Results from studies of men have been generalized to women, which may be inappropriate or even dangerous. Aim: The overall aim of this thesis was to describe women’s experience of a

The mystacocarid crustacean Derocheilocaris typica Pennak and Zinn, 1943 lives in sand interstices and is less than one mm long. It is unique among Arthropoda. It has sensory cells in the mandible, which lack cilia. The function as mechano- and/or chemo-receptors has been replaced by dendrites, the sensory cell protrusions carrying cilia. The dendrites swell, flatten, and fill the endite- a medial

The extreme ultraviolet (EUV) emission from few-times ionized tungsten atoms has been experimentally studied at the Livermore electron beam ion trap facility. The ions were produced and confined during low-energy operations of the EBIT-I electron beam ion trap. By varying the electron-beam energy from around 30-300 eV, tungsten ions in charge states expected to be abundant in tokamak divertor plas

The complement system is important for protection from invading pathogens, removal of waste products and guidance of the immune response. Furthermore, complement can be also targeted to cancer cells. However, membrane-bound inhibitors over-expressed by certain types of tumor cells restrict the cytotoxic activity of complement. Herein we report that non-small cell lung cancer (NSCLC) cells produce

We have conducted a detailed investigation of the broadband spectral properties of the gamma-ray selected blazars of the Fermi LAT Bright AGN Sample (LBAS). By combining our accurately estimated Fermi gamma-ray spectra with Swift, radio, infra-red, optical, and other hard X-ray/gamma-ray data, collected within 3 months of the LBAS data taking period, we were able to assemble high-quality and quasi

This doctoral thesis is a psychoanalytic interpretation of the novels of the Peruvian author Mario Vargas Llosa, and it explores these novels from three different perspectives, here called readings. The first perspective focuses on the literary techniques and the importance these may have for the interpretation of the content of the novels. This first reading includes a summary of the reception of

The McStas neutron ray-tracing simulation package is a versatile tool for producing accurate neutron simulations, extensively used for design and optimization of instruments, virtual experiments, data analysis and user training. In McStas, component organization and simulation flow is intrinsically linear: the neutron interacts with the beamline components in a sequential order, one by one. Histor

Contingent self-esteem, where one’s self-value is staked on success and competence, is a particularly vulnerable disposition with impact on well-being. This study compared physiological and behavioral reactivity between individuals self-rated as high and low in competence based self-esteem (N = 61), in a performance situation. To assess reactivity we used a traditional overt measure of blood press
