  1. 1. Control of reactive oxygen species homeostasis in response to environmental stress

    University dissertation from Stockholm : Department of Botany, Stockholm University

    Author : Malgorzata Plaszczyca; Katharina Pawlowski; Jean-Jacques Drevon; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stress; antioxidant defense; ascorbate peroxidase; aerenchyma; actinorhiza; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; växtfysiologi; Plant Physiology;

    Abstract : Plants are exposed to various fluctuations in their environmental conditions - light intensity, temperature, water status - and have to adapt in order to survive. Plant acclimatory responses can include the formation of new tissues, e.g., aerenchyma, or the activation of defense systems, e. READ MORE

  2. 2. Mammalian thioredoxin reductase 1 in antioxidant defense, regulation of adipocyte differentiation and as an anticancer drug target

    University dissertation from Stockholm : Karolinska Institutet, Dept of Medical Biochemistry and Biophysics

    Author : Xiaoxiao Peng; Karolinska Institutet.; Karolinska Institutet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Reactive oxygen species (ROS) are oxygen containing reactive molecules generated as by-products of cellular metabolism. At physiological concentrations, ROS acts as secondary messengers in cellular signaling transduction, but excessive amounts of ROS result in oxidative stress and cellular damage. READ MORE

  3. 3. Cell-Penetrating Peptides for Mitochondrial Targeting

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Carmine Pasquale Cerrato; Ülo Langel; Shana O. Kelley; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mitochondrial targeting; cell-penetrating peptides; antioxidant activity; scavenging ability; oligonucleotide delivery; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Mitochondria have simply been known as the cell’s powerhouse for a long time, with its vital function of producing ATP. However, substantially more attention was directed towards these organelles once they were recognized to perform several essential functions having an impact in cell biology, pharmaceutics and medicine.

  4. 4. The impact of cytochrome P4501-inhibitors on aryl hydrocarbon receptor signaling

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Johanna Bengtsson; Emma Wincent; Ulf Rannug; Malin Celander; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; molekylär biovetenskap; Molecular Bioscience;

    Abstract : The aryl hydrocarbon receptor (AHR) best known as a ligand-activated transcription factor that mediates toxic responses to xenobiotics such as dioxins, is also activated by certain endogenous compounds. Activation of the AHR up-regulates transcription of a large number of genes, including those encoding members of the cytochrome P450 1 family of enzymes (CYP1s). READ MORE

  5. 5. Cellulose Nanofibril-based Hybrid Materials Eco-friendly design towards separation and packaging applications

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Luis Valencia; Aji Mathew; Olli Ikkala; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibrils; hybrid materials; membranes; aerogels; separation; food packaging; materialkemi; Materials Chemistry;

    Abstract : Nanocellulose has been lately considered as the “Holy-Grail” in the design of sustainable materials due to its bio-origin and an unprecedented combination of prominent features, including good mechanical properties, anisotropy and versatile surface chemistry. In addition, nanocellulose in the form of cellulose nanofibrils, can adopt variable structures and morphologies depending on the processing technique, such as aerogels, films and monoliths. READ MORE
