    Abstract : 5-aminolevulinic acid (5-ALA) and derivatives thereof are widely usedprodrugs in treatment of pre-malignant skin diseases of the cancer treatmentmethod photodynamic therapy (PDT). The target molecule in 5-ALAPDTis protoporphyrin IX (PpIX), which is synthesized endogenously from5-ALA via the heme pathway in the cell. READ MORE

  4. 12. Towards membrane engineering as a tool in cell factory design: A case study on acetic acid tolerance in Saccharomyces cerevisiae

    Author : Lina Lindahl; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; butanol; inhibitors; lipidomics; Key words: Lignocellulose; Zygosaccharomyces bailii; molecular dynamics simulations; membrane permeability; carbon-14 uptake; ethanol; robustness;

    Abstract : The sustainable production of fuels, chemicals, and materials using renewable resources is a necessity if we are to reduce our ecological footprint and the rate of climate change. Lignocellulosic biomass, the major constituent of plant cell walls, is a renewable raw material with great potential due to its high abundance. READ MORE

  5. 13. A theoretical study of 5-Aminolevulinic acid and its esters : properties and lipid permeability

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biophysical chemistry; Biofysikalisk kemi; fysikalisk kemi; Physical Chemistry;

    Abstract : 5-aminolevulinic acid (5ALA) is a widely used prodrug in Photodynamic therapy (PDT). The target molecule in 5ALA-PDT is Protoporphyrin IX (PpIX), which is synthesized endogenously via the heme pathway in the cell. READ MORE

  6. 14. Membrane transport of triiodothyronine : With particular reference to erythrocytes in health and disease

    Author : Ann-Charlotte Holm; Nils Nordén; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Cellular T3 uptake was studied in three human cell systems, i.e. cultured lymphocytes, erythrocytes and erythrocyte membrane vesicles. READ MORE

  7. 15. Membrane Orientation Studies with Polarized Light Spectroscopy

    Author : Malin Ardhammar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lipid vesicle; membrane orientation; flow linear dichroism; oriented circular dichroism;

    Abstract : Lipid vesicles are versatile tools in modern biophysical science. They can be used as models of the cell membrane, to examine permeability, stability and behavior of molecules in the bilayer. They may act as transporters in a pharmacological context, designed to deliver their cargo to a certain place in the patient. READ MORE
