  1. 1. Discovery of Secondary Metabolites from Rwandese Medicinal Plants : Isolation, Characterization and Biological Activity

    Author : Daniel Umereweneza; Máté Erdélyi; A Gogoll; Théoneste Muhizi; Yngve Stenstrøm; Uppsala universitet; []
    Keywords : Natural products; Nuclear Magnetic Resonance NMR ; Dihydrochalcones; Iridoids; Silphiperfolanols; Pyrrolizidine alkaloids PAs ; Rwandese Medicinal Plants; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Plants have served as the principal source of medicines in different parts of the world through the ages. Herb-derived medicines have been used as decoctions, infusions, tinctures or single substance drugs. READ MORE

  2. 2. Salt-inducible kinase 1 : a novel regulator within a cell sodium-sensing network

    Author : Karin Stenström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Na ; K -ATPase; -adducin; Milan hypertensive and normotensive strain of rats; hypertension; angiotensin II; cardiac hypertrophy; myocyte enhancer factor-2 and nuclear factor of activated T-cells;

    Abstract : Na+, K+-ATPase (NK) is expressed in all animal cells and plays a crucial role in cellular ion homeostasis. The NK activity is tightly regulated by specific signaling networks that must be well controlled in time and space (at the plasma membrane or in the intracellular compartments) to guarantee the specificity of the physiological response.

  3. 3. Surviving the loss of a child, a spouse, or both : Implications on life satisfaction and mortality in older ages

    Author : Anna S. Bratt; Mikael Rennemark; Ulf Stenström; Gerd Ahlström; Linnéuniversitetet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; negative life events; child and spouse loss; bereavement; older adults; Psychology; Psykologi;

    Abstract : Losing a loved one – a child or a spouse –is described as one of the most stressful or negative experience of a person’s life. Aging is associated with a higher risk of the death of close family members, yet few studies have investigated the impact of such losses on different health outcomes either by type of loss or by the combined loss of both a child and a spouse.

  4. 4. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation

    Author : Christer Stenström; Pär Jonsén; Kjell Eriksson; Ugo Galvanetto; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peridynamics; J-integral; Essential work of fracture; Nonlocal methods; Meshless; Meshfree; Fracture; Crack tip; Exact analytical; Center cracked tension; Double edge notched tensile; fracture toughness; Peridynamik; Brottmekanik; Sprickspets; Brottseghet; Spänningsintensitet; Hållfasthetslära; Solid Mechanics;

    Abstract : Fracture toughness is one of the most important properties of a material. Being able toaccurately estimate the energy that goes into forming new crack surfaces is essential for the development of new materials, quality assurance, structural monitoring and failure analysis. READ MORE
