  1. 11. De-icing salt and the roadside environment : Air-borne exposure, damage to Norway spruce and system monitoring

    Författare :Göran Blomqvist; KTH; []
    Nyckelord :road; de-icing salt; air-borne; environmental impact; vegetation damage; Norway spruce; seedling; follow-up; monitoring; indicator;

    Sammanfattning : After decades of investigation, we still have to deal withthe problem of environmental effects of the use of de-icingsalt on roads. Lacking useful indicators of the system, westill do not know the environmental utility of ameliorativemeasures taken. LÄS MER

  3. 12. Angiotensin II and vascular disease. Studies in rats and atherosclerosis-prone mice

    Författare :Maria E Johansson; Göteborgs universitet; []
    Nyckelord :angiotensin II; atherosclerosis; AT1 receptor; AT2 receptor; blood pressure; hyperinsulinemia; hypertension; oxidative stress; salt; vascular disease; vascular function;

    Sammanfattning : Angiotensin II (Ang II) is of importance for a number of physiological processes but also plays an important pathophysiological role in cardiovascular disease. The aim of this thesis was to evaluate the role of Ang II in hypertension-related atherosclerosis and vascular disease and to investigate possible anti-atherosclerotic effects of the angiotensin II, type 2 (AT2) receptor.

  5. 14. Impact of the upper gut on body fluid regulation and blood pressure in man - potential involvement of a locally expressed renin-angiotensin system

    Författare :Peter Hallersund; Göteborgs universitet; []
    Nyckelord :angiotensin; stomach; duodenum; sodium; salt; diuresis; appetite; gastric bypass; blood pressure;

    Sammanfattning : This thesis explores the role of the upper gut in the regulation of diuresis and blood pressure control in relation to the novel finding of a mucosa-located renin-angiotensin system (RAS). RAS is a regulatory super-system vital for body fluid homeostasis and blood pressure control. LÄS MER

  7. 15. Development and Evaluation of Preparation Methods for the Analysis of Cell Membranes Using Time-of-Flight Secondary Ion Mass Spectrometry

    Författare :Jakob Malm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; salt; cryofixation; TOF-SIMS; supported phospholipid bilayer; freeze drying; vacuum; cells; POPC; glutaraldehyde;

    Sammanfattning : The aim of this work was to evaluate and develop methods for preparing dry samples for TOF-SIMS analysis of cell membranes. For correct interpretation of the analysis data, an understanding of the effects that the preparation method has on the morphology and chemical structure of the sample must first be obtained. LÄS MER
