  2. 21. Asymmetric Cellular Microenvironments

    Author : Susanna Rydholm; Hjalmar Brismar; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : This thesis presents methods to combine 3D cell culture, microfluidics and gradients on a controlled cellular scale. 3D cultures in biological extracellular matrix gels or synthetic gels bridge the gap between organ-tissue cultures and traditional 2D cultures. READ MORE

  4. 22. Focused Ion Beam Preparation and Transmission Electron Microscopy of Materials for Energy Applications

    Author : Filip Lenrick; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transmission electron microscopy; focused ion beam; solid oxide materials; fuel cell; semiconductor materials; nanowire; LED; solar cell;

    Abstract : Throughout this thesis, samples of various materials with applications in energy converting devices have been prepared by focused ion beam machining and investigated by transmission electron microscopy. Energy converting devices can be solar cells or light emitting diodes, which turn light into electricity or vice versa. READ MORE

  5. 23. Mechanism behind the development of radiation-induced cardiovascular effects

    Author : Venkata Ramesh Yentrapalli; Siamak Haghdoost; Andrzej Wojcik; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molekylärgenetik; Molecular Genetics;

    Abstract : Epidemiological studies on acutely and chronically exposed individuals indicate that ionising radiation could be a risk factor for cardiovascular diseases. Experimental data regarding radiation-induced cardiovascular late effects are limited and biological mechanisms behind these late effects are still unclear. READ MORE

  6. 24. Deciphering cell motility and spatial sensing of intestinal cell types using an ex vivo intestinal model

    Author : Anna Webb; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The intestine is a highly organized tissue with two distinct regions: the crypt and the villus. When stem cells divide at the crypt bottom, half of their progeny migrates upwards towards the villus, where they differentiate into various cell types, including the abundant absorptive enterocytes.

  7. 25. Analysis of Genes and Proteins Involved in Wood Formation

    Author : Anders Winzell; Tuula Teeri; Alan Marchant; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Abstract : SAMMANFATTNING Vedbildning är en underliggande mekanism för så skilda områden som industri, boende och en hållbar miljö. Vedbildning sker i det vaskulära kambiet där organiserade celldelningar åtföljs av differentiering till specialiserade vedceller. READ MORE
