  2. 16. Assessment of precursor cell proliferation in normal and injured adult mammalian brains

    Author : Hong Zhu; Göteborgs universitet; []
    Keywords : 6-OHDA; astrocytes; cell proliferation; neural stem cells; ; neurogenesis; precursor cells; seizure; SVZ-OB pathway;

    Abstract : In the adult mammalian brain, new neurons are generated from neural stem cells (NSCs) which reside in the subventricular zone (SVZ) of the lateral ventricle wall and in the subgranular zone (SGZ) of the dentate gyrus (DG) in the hippocampus. The biology of persistent NSCs in the adult brain is poorly understood. READ MORE

  4. 17. Mechanosensing in the vascular wall - the role of cellular microdomains in vascular remodeling

    Author : Sebastian Albinsson; Kärlfysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur; cytochemistry; histochemistry; wall stress; shear stress; hypertension; Histology; differentiation; growth; caveolin; smooth muscle; actin; Fysiologi; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : The vascular wall has a remarkable capacity to adapt to mechanical forces exerted by the intraluminal blood pressure and flow. This includes rapid change in contractile tone as well as chronic alteration of vessel structure if the stimulus persists. Stretch of the intact blood vessel wall promotes growth and contractile differentiation. READ MORE

  5. 18. Transition metal ion-chelating ordered mesoporous carbons as noble metal-free fuel cell catalysts

    Author : Johanna Dombrovskis; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mesoporous materials; electrocatalysis; EXAFS spectroscopy; fuel cell; transition metals; carbon;

    Abstract : Polymer electrolyte membrane fuel cells offer promising possibilities for clean and efficient chemical to electrical energy conversion, though their high price makes them financially unappealing. This is to a large part due to the high cost of the noble metal catalyst used in fuel cells, which makes development of new, cheap and active catalyst materials necessary. READ MORE

  6. 19. Targeting cell envelope synthesis of Streptococcus pneumoniae and microfluidic diagnostic tool development

    Author : Elisabeth Reithuber; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Evolving antibiotic resistance warrants the development of new therapeutic and diagnostic approaches as part of the strategies to secure future antibacterial therapies and preserve the compounds currently available. Work constituting the thesis characterized small molecules yielded from a screen for autolysis inducing compounds on Streptococcus pneumoniae. READ MORE

  7. 20. Structural studies of enzymes regulating bacterial life style and cell wall biogenesis

    Author : Ming Wei Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Bacteria can adapt to different biotic and abiotic environments by changing their life style, switching between sessile or motile, free-living or community-bound, virulent or dormant states. Each bacterium also faces the challenges of maintaining a protective barrier while growing, replicating and responding to environmental changes. READ MORE
