  3. 12. Stelar Performance Under Drought : Regulation of Developmental Robustness and Plasticity of the Arabidopsis Root Xylem

    Författare :Prashanth Ramachandran; Annelie Carlsbecker; Ari Pekka Mähönen; Uppsala universitet; []
    Nyckelord :HD-ZIP III TFs; miR165; Xylem; ABA; VND; plasticity; water deficit; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Sammanfattning : Plants have evolved genetic mechanisms to sense, modulate and modify developmental programs in response to the changing environment. This brings forth challenges in stably generating tissue patterns while simultaneously allowing amenability. LÄS MER

  4. 13. Short- and long-term neuronal plasticity in hippocampal CA1 region of rat

    Författare :Fen-Sheng Huang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glutamate; hippocampus; plasticity; synapse; LTP; LTD; AMPA; NMDA;

    Sammanfattning : The brain is highly plastic, displaying both short- and long-term changes, resulting from developmental processes as well as learning and memory. Moreover, short-term plasticity such as paired pulse facilitation and depression (PPF, PPD) have long been used to monitor the presynaptic versus postsynaptic changes occurring during more lasting processes such as long-term potentiation and depression (LTP, LTD).

  5. 14. Integrative modeling of intratumoral heterogeneity, plasticity and regulation in nervous system cancers

    Författare :Ida Larsson; Sven Nelander; Fredrik Swartling; Patrik Johansson; Itay Tirosh; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nervous system cancer; Glioblastoma; Heterogeneity; Plasticity; Mathematical modeling; Oncology; Onkologi;

    Sammanfattning : The adult brain tumor glioblastoma (GBM) is characterized by short survival and a lack of efficient treatments. Median survival is 15 months from time of diagnosis and the 5-year survival rate is only 7 %. LÄS MER

  7. 15. Defence on Demand : A physiological perspective on phenotypic plasticity in anti-predator traits

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phenotypic plasticity; inducible defences; stress physiology; cortisol; immune function; trade-offs; sexual dimorphism; crucian carp; visual ecology; predator-prey interactions; POMC pro-opiomelanocortin ; colour change; eco-immunology; Anti-predator defences; Inducible morphological defence; Phenotypic plasticity; Stress physiology; Cortisol; Immune function; Crucian carp; Predator-prey interactions; Trade-offs; Sexual dimorphism; POMC; Pro-opiomelanocortin; Visual ecology; Eye evolution; Melanin; Eco-immunology; Pace-of-life; Behavioural plasticity;

    Sammanfattning : Almost all species face some degree of predation risk, and, hence, evolution has produced a plethora of anti-predator defences. However, anti-predator strategies require resources, and the prevailing risk of becoming prey is influenced by many factors and rarely constant across time and space. LÄS MER
