Popular Abstract in Swedish Polyaminer finns i alla levande celler, såväl i bakterier som i växter, djur och människor, och utgör en mycket viktig beståndsdel i dessa. Utan dessa polyaminer kan inte cellerna växa och dela sig. Polyaminerna putrescin, spermidin och spermin bildas i cellen från aminosyran ornitin. Till sin hjälp för denna bildning har cellerna ett enzym vid namn ornitindekarboxylas The polyamines putrescine, spermidine and spermine have been shown to be involved in cell growth and differentiation, and are considered to be crucial components of the living cell. The synthesis of polyamines in the cell is strictly regulated. The first and rate-limiting step in the biosynthesis of polyamines is catalysed by the enzyme ornithine decarboxylase (ODC). Mammalian ODC has a very fast

The main objectives with this investigation are firstly to compare important parameters of a capacitive micromachined ultrasonic transducer (cMUT) for air applications with a corresponding piezoelectric ultrasonic transducer. Secondly, to characterise the cMUT's radiation field using light diffraction tomography. The cMUTs consist of a silicon backplate with small pyramid-shaped cavities and a met

The biological functions of proteins depend on their physical interactions with other molecules, such as proteins and peptides. Therefore, modeling the protein-ligand interactions is important for understanding protein functions in different biological processes. We have focused on the cleavage specificities of HIV-1 protease, HCV NS3 protease and caspases on short oligopeptides or in native prote

The aim of the present study is to contribute to the documentation and interpretation of the image and experience of the human body. This image was first formulated in the 16th and 17th centuries by among others René Descartes, and it was given various visual shapes by artists connected with the academies of art from that time on. The intention of my investigation is to discuss some traits of what

Geophysical methods are increasingly being applied to geotechnical investigations, as they can identify material properties and material boundaries, as well as variations in space and time of relatively large volumes of soil. Another advantage is that many of these methods are non-intrusive. The combination of several methods and the verification of their results by sampling and correlating with g
