  1. 1. Absorption and accumulation of cadmium from cereal grains

    University dissertation from Umeå : Umeå universitet

    Author : Anncatherine Moberg Wing; Umeå universitet.; Umeå universitet.; Umeå universitet.; Umeå universitet.; [1993]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cadmium accumulation; cereal grains; dietary fiber; iron status; pregnancy;

    Abstract : Cadmium (Cd) is a potentially toxic trace element. Cereal grains contribute one-third to one-half of the Cd exposure via the diet. Among cereal grains, wheat generally contains the highest Cd concentration and the bran and germ fractions contain more Cd than the endosperm. READ MORE

  2. 2. Regulatory pathways and virulence inhibition in Listeria monocytogenes

    University dissertation from Umeå : Umeå Universitet

    Author : Christopher Andersson; Umeå universitet.; Umeå universitet.; Umeå universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Listeria monocytogenes; PrfA; ActA; infection; molekylärbiologi; Molecular Biology;

    Abstract : Listeria monocytogenes is a rod-shaped Gram positive bacterium. It generally exist ubiquitously in nature, where it lives as a saprophyte. Occasionally it however enters the food chain, from where it can be ingested by humans and cause gastro-intestinal distress. In immunocompetent individuals L. READ MORE

  3. 3. Yersinia-phagocyte interactions during early infection

    University dissertation from Umeå : Umeå universitet

    Author : Linda Westermark; Umeå universitet.; Umeå universitet.; Umeå universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia; dendritic cell; macrophage; neutrophil; T3SS; Infectious Diseases; infektionssjukdomar;

    Abstract : Pathogenic Gram-negative Yersinia species preferentially target and inactivate phagocytic cells of the innate immune defense by translocation of effector Yersinia outer proteins (Yops) into the cells via a type III secretion system. This indicates that inactivation and avoidance of the early innate immune response is an efficient way for Yersinia species to avoid elimination and to cause diseases ranging from mild gastroenteritis (Y.

  4. 4. A sensory role for the cruciate ligaments regulation of joint stability via reflexes onto the γ-muscle-spindle system

    University dissertation from Umeå : Umeå universitet

    Author : Per Sjölander; Umeå universitet.; [1989]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Joint afferent; Mechanoreceptor; Cruciate ligament; Fusimotor neuron; reflex; muscle spindle afferent; motor control; cat;

    Abstract : Reflex effects evoked by graded electrical stimulation of the posterior articular nerves (PAN) of the ipsi- and contralateral knee joints were investigated using both micro-electrode recordings from 7 - motoneurones and recordings from single muscle muscle spindle afferents. Spindle afferent responses were also recorded using natural stimulation of different types of receptors, to elucidate if the articular reflexes onto the y -motoneurones were potent enough to significantly alter the muscle spindle afferent activity.

  5. 5. The Role of the Forest in Climate Policy

    University dissertation from Umeå : Umeå Universitet

    Author : Mathilda Eriksson; Umeå universitet.; Umeå universitet.; [2016]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change; integrated assessment; forest carbon sequestration; forest bioenergy; avoided deforestation; afforestation; uncertainty; dynamic modeling; DICE; RICE; nationalekonomi; Economics;

    Abstract : AbstractIn Paper [I], I develop the FOR-DICE model to analyze optimal global forest carbon management. The FOR-DICE is a simple framework for assessing the role of the boreal, tropical, and temperate forests as both a source of renewable energy and a resource to sequester and store carbon. READ MORE
