2. 1. The oxidative stress response of Francisella tularensis

   Author : Marie Honn; Anders Sjöstedt; Helena Lindgren; Andres Melendez; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella tularensis; FupA; MglA; OxyR; ROS; oxidative stress; molekylärbiologi; Molecular Biology;

   Abstract : Francisella tularensis is capable of infecting numerous cell types, including professional phagocytes. Upon phagocytosis, F. tularensis resides within the phagosome before escaping into the cytosol to replicate. Phagocytes constitute a hostile environment rich in ROS, which are employed as a means of killing pathogens. READ MORE

4. 2. RsbX and stress response in Listeria monocytogenes

   Author : Ana Henriques de Oliveira; Jörgen Johansson; Cormac Gahan; Umeå universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Listeria monocytogenes; SigB; stressosome; RsbX; phosphorylation; growth; competitiveness; motility; energetic cost; homeostasis; stress response; virulence; invasion; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

   Abstract : Listeria monocytogenes is a ubiquitous foodborne Gram-positive bacterium. Despite being mainly a soil bacterium, it can reach the food processing environment and contaminate food destined for human consumption, causing outbreaks. READ MORE

5. 3. Stress response and virulence in Vibrio anguillarum

   Author : Barbara Weber; Debra L. Milton; James D. Oliver; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Vibrio anguillarum; quorum sensing; Type VI secretion; stress response; virulence; skin colonization; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Abstract : Bacteria use quorum sensing, a cell to cell signaling mechanism mediated by small molecules that are produced by specific signal molecule synthases, to regulate gene expression in response to population density. In Vibrio anguillarum, the quorum-sensing phosphorelay channels information from three hybrid sensor kinases VanN, VanQ, CqsS that sense signal molecules produced by the synthases VanM, VanS and CqsA, onto the phosphotransferase VanU, to regulate activity of the response regulator VanO.

6. 4. Domestication Effects on the Stress Response in Chickens : Genetics, Physiology, and Behaviour

   Author : Amir Fallahshahroudi; Per Jensen; Frank Albert; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Animal domestication; stress response; gene expression; QTL; eQTL;

   Abstract : Animal domestication, the process where animals become adapted to living in proximity to humans, is associated with the alteration of multiple traits, including decreased fearfulness and stress response. With an estimated population of 50 billion, the domesticated chicken is the most populous avian species in the world. READ MORE

7. 5. Trauma - logistics and stress response

   Author : Camilla Brorsson; Silvana Naredi; Anders Sylvan; Per Dahlqvist; Mikael Bodelsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; multiple trauma; hydrocortisone; adrenal insufficiency; hypnotics and sedatives; citric acid; glycerol; saliva; liver; colorectal surgery;

   Abstract : Background: Trauma is a major cause of death and disability. Adverse events, such as prolonged prehospital time, hypoxia, hypotension and/or hyperventilation have been reported to correlate to poor outcome.Adequate cortisol levels are essential for survival after major trauma.
