  1. 1. Coping with Stress Regulation of the Caulobacter crescentus cell cycle in response to environmental cues

    Detta är en avhandling från Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Författare :Kristina Heinrich; Stockholms universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Caulobacter crescentus; bacteria; cell cycle; stress; filamentation; cell morphology; DNA replication; cell division; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : All organisms have to respond to environmental changes to maintain cellular and genome integrity. In particular, unicellular organisms like bacteria must be able to analyze their surroundings and rapidly adjust their growth mode and cell cycle program in response to environmental changes, such as changes in nutrient availability, temperature, osmolarity, or pH.

    Sammanfattning : The life of a preterm infant admitted to a neonatal intensive care unit may be stressful from the moment of birth. Ever since Hans Selye’s initial characterisation of the biological stress response, cortisol has been frequently measured as an indicator of stress responsivity. LÄS MER

  3. 3. Stress in chickens Effects of domestication and early experience on behaviour and welfare

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Maria Ericsson; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The domestication is the process where animals have adapted to human conditions. A prerequisite for domestication is tame behaviour towards humans and subsequently, selection for other desirable traits took place which led to changes in several behavioural and physiological parameters.

  4. 4. Studies on stress in African green monkeys (Cercopithecus aethiops) : Stress associated cortisol and prolactin levels, lymphocyte modulation and pathological changes in adrenal cortex, stomach and hippocampus in the African green monkey (C. aethiops)

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mbaruk Abdalla Suleman; Uppsala universitet.; [1998]

    Sammanfattning : African green monkeys (AGMs) are highly susceptible to captivity-induced stress. An investigation of spontaneous deaths of laboratory confined AGMs at the Institute of Primate Research, Nairobi, Kenya over a period of 7.5 years documented mild to severe gastric mucosal erosions and ulcers in 83 of 260 (32%) necropsies.

    Sammanfattning : Experiences early in life or during adolescence modulate neuronal networks in the immature brain and consequently lay the foundation for future susceptibility or resilience towards psychiatric disorders. The objective in this thesis is to understand, in part, how the surrounding environment shapes the brain of a young individual. LÄS MER
