  2. 11. Neutrophil chemotaxis. Analyses of neutrophil chemotaxis i a new fluid gradient chamber

    Author : Reza Ebrahimzadeh Pirshahid; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell movement; Chemotaxis; Leukocyte; Neutrophil; Human; Filter; Methods; N-Formylmethionine-Leucyl-Phenylalanine; Normal distribution; Partial differential equation;

    Abstract : The leukocytes have, as part of their function in immune system, the ability to leave the bloodstream, penetrate the vascular wall and migrate towards extravascular targets. This behaviour of the leukocytes has been extensively studied both in vivo and in vitro since the 19th century but the mechanisms underlying leukocyte migration are not yet fully understood.

  4. 12. Medin Amyloid in Human Arteries and its Association with Arterial Diseases

    Author : Siwei Peng; Per Wstermark; Gunnar Husby; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; Amyloid; Medin; Lactadherin; Aneurysm; Aortic dissection; Temporal artery; Arteritis; Giant cell; Pre-aggregation.; Patologi; Pathology; Patologi;

    Abstract : Amyloid is a form of abnormal protein aggregation within the living body. Massive deposits can lead to organ failure. There is also increasing evidence that smaller pre-amyloid aggregates exert direct toxic effects to cells. READ MORE

  5. 13. Endothelial Nitric Oxide in the Control of Glomerular Hemodynamics

    Author : János Pittner; Daniel H. Casellas; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Juxtamedullary nephron; afferent arteriole; nitric oxide; endothelial calcium; diaminofluoresceins; fura-2; autoregulation; shear stress; flow; videomicroscopy; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Abstract : The afferent arteriole of the kidney is a unique vascular segment: it is the effector of the renal hemodynamic autoregulation. The use of the isolated, perfused juxtamedullary nephron preparation makes it possible to visualize the afferent arteriole while preserving its tissue surroundings and the functional integrity of the nephron.

  6. 14. Acetylation of polysaccharides in plant cell wall : with a focus on woody species

    Author : Prashant Mohan Pawar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Plant cell wall in woody tissues is a complex matrix, which consists of cellulose, matrix polysaccharides and lignin. The matrix polysaccharides are substituted with acetyl group that are hypothesised to play important roles in determining properties of these polysaccharides. READ MORE

  7. 15. Uncovering novel cell wall chemistries in gram negative bacteria : from development or dedicated peptidoglycan chemometric tools to functional genomics

    Author : Akbar Espaillat; Felipe Cava; Sun Nyunt Wai; Waldemar Vollmer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacteria; cell wall; peptidoglycan; peptidoglycan variations; D-amino acids; molekylärbiologi; Molecular Biology;

    Abstract : Bacteria are surrounded by an external cell wall whose main component is a polymeric net-like structure called the peptidoglycan (PG) or murein sacculus. PG plays crucial roles in bacterial physiology (eg morphogenesis, growth fitness and regulation of innate immunity). READ MORE
