  2. 6. Experimental studies on glioma cell motility and proliferation

    Author : Adila Salih El-Obeid; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; glioma; TGF-α; EGFR; GFAP; motility; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Abstract : Glioma is a malignant primary brain tumor associated with short patient survival. Various growth factors and cytoskeletal proteins are correlated to glioma progression. In this thesis the effects of transforming growth factor alpha (TGFα) and glial fibrillary acidic protein (GFAP) were studied. READ MORE

  4. 7. Regulation of Duodenal Mucosal Barrier Function and Motility : The Impact of Melatonin

    Author : Anna Sommansson; Markus Sjöblom; Olof Nylander; Oliver Bachmann; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; bicarbonate secretion; duodenum; enteric nervous system; enterochromaffin cell; ethanol; hexamethonium; in vivo; mecamylamine; motility; mucosal permeability; parecoxib; rat; Physiology; Fysiologi;

    Abstract : The duodenal mucosa is regularly exposed to acid, digestive enzymes and ingested noxious agents. It is thus critical to maintain a protective barrier to prevent the development of mucosal injury and inflammation, which are often observed in situations when barrier function is impaired.

  5. 8. Metabolism-dependent taxis and control of motility in Pseudomonas putida

    Author : Sofia Österberg; Vicky Shingler; Caroline Harwood; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Motility; c-di-GMP; metabolism-dependent taxis; receptors; transcription; Pseudomonas putida; molekylärbiologi; Molecular Biology;

    Abstract : Bacteria living in soil and aquatic habitats rapidly adapt to changes in physico-chemical parameters that influence their energy status and thus their ability to proliferate and survive. One immediate survival strategy is to relocate to more metabolically optimal environments. READ MORE

  6. 9. Activation, adhesion and motility of B lymphocytes in health and disease

    Author : Natalija Gerasimcik; Eva Severinson; Victor Tybulewicz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; B cells; activation; motility; IL-4; EBV; Dock10; Cdc42; Rac1 and Rac2; immunologi; Immunology;

    Abstract : B cells can be activated by T cell-dependent stimuli, such as CD40 ligation and cytokines, which induce extensive proliferation, class switch recombination and somatic hypermutation.Epstein-Barr virus (EBV) can also induce B cell activation by mimicking T cell help through its main oncoprotein, latent membrane protein 1 (LMP-1).

  7. 10. Role of Melatonin, Neuropeptide S and Short Chain Fatty Acids in Regulation of Duodenal Mucosal Barrier Function and Motility

    Author : Wan Salman Wan Saudi; Markus Sjöblom; Olof Nylander; Mark Berner-Hansen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; rat; in vivo; duodenum; enteric nervous system; paralytic ileus; parecoxib; bicarbonate secretion; motility; ethanol; HCl; melatonin; neuropeptide S; short chain fatty acids; chemosensing; Physiology; Fysiologi;

    Abstract : The duodenal epithelium is regularly exposed to HCl, digestive enzymes, bacteria and toxins, and sometimes also to ethanol and drugs. The imbalance of aggressive factors in the intestinal lumen and mucosal barrier function increases the risk of tissue injury and inflammation. READ MORE
