  1. 1. Proteostasis in Bacillus subtilis : chaperones and stress-response mechanisms

    Författare :Judith Matavacas; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein homeostasis; Chaperones; DnaK; trigger factor; Spx; YjbH; Bacillus subtilis;

    Sammanfattning : The maintenance of protein homeostasis, also referred to as proteostasis, is essential for preserving the structural and functional stability of the proteome in living organisms. This involves the precise control of protein synthesis, folding, and degradation. LÄS MER

  3. 2. Bacterial Adaptive Responses - Coping with Oxygen Limitation, Reactive Nitrogen Species and Disulfide Stress

    Författare :Annika Rogstam; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacillus subtilis; redox regulation; nitrosative stress; disulfide stress;

    Sammanfattning : Bacteria have a remarkable ability to adapt to different environments. When bacteria encounter stress that causes macromolecular damage in the cell, leading to a suboptimal performance of cell metabolism, they can elicit an adaptive response. LÄS MER

  4. 3. Redox Regulation and Stress Responses - Studies in Bacillus subtilis

    Författare :Jonas Larsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; redox sensor; oxygen sensor; reactive nitrogen species; RNS; Biology; Biologi; Microbiology; bacteriology; virology; mycology; bakteriologi; Mikrobiologi; virologi; mykologi; Bacillus subtilis; Rex; yjbI; ydiH; yjbH; redox regulation;

    Sammanfattning : Redox reactions are central to all organisms to sustain life. Both anabolic and catabolic metabolism depends on them. It is thus vital to sense and adjust the redox balance in the cell. One major factor affecting the redox status is the level of oxygen present. LÄS MER

  5. 4. Asymptotics of implied volatility in the Gatheral double stochastic volatility model

    Författare :Mohammed Albuhayri; Anatoliy Malyarenko; Sergei Silvestrov; Ying Ni; Christopher Engström; Yulia Mishura; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : We consider a market model of financial engineering with three factors represented by three correlated Brownian motions. The volatility of the risky asset in this model is the sum of two stochastic volatilities. The dynamic of each volatility is governed by a mean-reverting process. LÄS MER
