Human epidermal growth factor receptor 2 (HER2) is overexpressed and/or amplified in 15-20% of all breast cancers, and is associated with an aggressive tumour type with impaired prognosis and a predictive marker for trastuzumab treatment. HER2 status can be determined by immunohistochemistry (IHC) at protein level and by fluorescence in situ hybridisation (FISH) analysing gene amplification, and i

The cholesterol-lowering effect of oats is well established, but the crucial properties eliciting this effect need to be further investigated to optimize the use of oats as functional foods. Furthermore, there are almost no reports investigating the effect of oats on atherosclerosis development. This thesis describes our work with finding suitable mouse models to study cholesterol-lowering and ant

Monoclonal anti-collagen type II antibody CIIC1 is an arthritogenic autoantibody, which induces arthritis in mice. We crystallized and solved the structure of CIIC1 Fab molecule. Analysis of structure revealed an interaction between the CDR regions of one Fab to the CH1 domain of another Fab, which resembles an antibody-antigen interaction. ELISA experiments confirmed the cross-reactivity of both

Object: This study investigates the outcome after traumatic brain injury (TBI) in mice lacking the essential DNA repair gene xeroderma pigmentosum group A (XPA). As damage to DNA has been implicated in neuronal cell death in various models, the authors sought to elucidate whether the absence of an essential DNA repair factor would affect the outcome of TBI in an experimental setting. Methods: Th

Fuel cells are promising for future energy systems, since they are energy efficient and, when hydrogen is used as fuel, there are no emissions of greenhouse gases. Fuel cells have during recent years various improvements, however the technology is still in the early phases of development. This can be noted by the lack of a dominant design both for singe fuel cells, stacks and for entire fuel cell

Many studies have reported higher total plasma homocysteine (tHcy) in elderly patients with mental illness than in control subjects. There are many different determinants of plasma tHcy concentration, including age, cobalamin/folate status, renal function and the presence of vascular disease. The presence of vascular disease may contribute to cognitive impairment. We have investigated elderly pati

OBJECTIVE: Heart rupture is a devastating complication to negative pressure wound therapy in cardiac surgery. Also, reduced cardiac output during negative pressure wound therapy has been reported. The present study aimed to examine the effects of negative pressure wound therapy on the position of the heart in relation to the thoracic wall using magnetic resonance imaging in a porcine sternotomy wo

Remote laser-induced fluorescence monitoring can complement passive reflectance measurements on vegetation. Vegetation classification and status assessment is normally performed by air- or spaceborne multi-spectral scanners. An increased research activity in the field of vegetation monitoring is motivated by the abundant stressed forests of Europe. We have used a mobile lidar system for remote stu
