1. Parietal cell regeneration in rat gastric mucosal wounds : a quantitative light and electron microscopical study
Sammanfattning : The aims of the study were to obtain a method with which it would be possible to produce standardized wounds in the gastric mucosa, and to follow the regeneration of the acid producing parietal cells in those lesions during different experimental conditions. Quantitative methods applied to light and electron microscopy were used. LÄS MER
Sammanfattning : Disruptions are dangerous instabilities in tokamaks that should be avoided or mitigated. One possible disruption mitigation method is to inject impurities into the plasma to shut it down in a controlled way. Runaway Electrons (REs) can be generated after the plasma is cooled down bythe impurities and these electrons can damage the tokamak. LÄS MER
3. The molecular biology of retinoid metabolism : Identification of an 11-cis retinol dehydrogenase in the retinal pigment epithelium
Sammanfattning : Vitamin A derivatives (retinoids) are essential molecules in the course of embryonic development, postnatal growth and adult physiology. The physiological functions of retinoids are thought to be mediated mainly by retinoic acid which regulates the expression of various genes, and 11-cis retinaldehyde, which is the common chromophore of visual pigments.

Sammanfattning : In order for the innovation process to be successful, not only do innovations need to be developed and reached the market, but, once they are available for users, they have to spread on a large scale. In the innovation literature, a complete explanation is lacking of why some innovations reach a phase of large-scale diffusion faster than others, including both actor- and system-level components.
