  1. 1. Gastrointestinal mucosal protective mechanisms : Mudolatory effects of Heliobacter pyroli on the gastric mucus gel barrier and mucosal blood flow in vivo

    Author : Christer Atuma; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mucus gel layer; mucosal blood flow; mucus thickness; chronic infection; rat; platelet activating factor; mast cell; nitric oxide; nitric oxide synthase; ketotifen; intra-vital microscopy; microelectrode; laser-Doppler flowmetry; L- NNA; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : The gastrointestinal mucus gel layer and blood flow are two important mechanisms for protection at the pre-epithelial and sub-epithelial levels, respectively. Helicobacter pylori might circumvent these mechanisms and elicit a chronic inflammatory response with consequent ulcers in the stomach and duodenum. READ MORE

  2. 2. Surface proteins of pathogenic streptococci

    Author : Thomas Areschoug; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Microbiology; factor H; complement regulator; CD89; human IgA; protective immunity; surface protein; Streptococcus pyogenes; group B streptococcus;

    Abstract : Streptococcus pyogenes (group A streptococcus) and the group B streptococcus (GBS) are two important human pathogens that cause different types of diseases and express different surface structures implicated in virulence. This thesis focuses on several surface proteins expressed by these pathogens, analyzing the biological function of these proteins and their ability to elicit protective immunity. READ MORE

  3. 3. Superoxide dismutase 1 and amyotrophic lateral sclerosis

    Author : P. Andreas Jonsson; Stefan L. Marklund; David R. Borchelt; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; aggregates; ALS; amyotrophic lateral sclerosis; cerebrospinal fluid; disulfide-reduced; inclusions; misfolded; protective factor; SOD1; transgenic; Neurovetenskap; Neurology; Neurologi; Clinical Chemistry; klinisk kemi;

    Abstract : Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting motor neurons in the spinal cord, brain stem and motor cortex, leading to paralysis, respiratory failure and death. In about 5% of ALS cases, the disease is associated with mutations in the CuZn-superoxide dismutase (hSOD1) gene. READ MORE

  4. 4. Plasmin : a potent pro-inflammatory factor

    Author : Yongzhi Guo; Tor Ny; Dick Heinegård; Umeå universitet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; plasmin; inflammation; rheumatoid arthritis; bacterial arthritis; infection; sepsis; cytokine; signal transduction; Pathology; Patologi;

    Abstract : Plasmin, the central molecule of the plasminogen activator system, is a broad-spectrum serine protease. Plasmin is important for the degradation of fibrin and other components of the extracellular matrix (ECM) during a number of physiological and pathological processes. READ MORE

  5. 5. Antisecretory factor in the perinatal period

    Author : Anna Gustafsson; Karolinska Institutet; Karolinska Institutet; []

    Abstract : Preterm birth is the major cause of neonatal morbidity and mortality. Human milk, especially mothers’ own milk, has many health benefits for infants, especially infants born preterm. The causes of preterm birth are not yet fully understood. READ MORE
