  2. 21. Sensor Systems for Bioprocess Monitoring

    Author : Helena Lidén; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; on-line; pattern recognition; gas sensor array; electronic nose; monosaccharides; ethanol; biosensor; carbon paste electrode; Analytical chemistry; Analytisk kemi;

    Abstract : Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. READ MORE

  4. 22. Enhanced Enzymatic Hydrolysis of Lignocellulose in Bioethanol Production Substrate Interactions with Surfactants and Polymers

    Author : Johan Börjesson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzymologi; Penicillium brasilianum; SSF; Ethanol; Proteins; enzymology; Proteiner; Protease; Adsorption; PEG; Surfactant; Hydrolysis; Lignocellulose; Cellulase; Hypocrea jecorina; Trichoderma reesei; Cellulose;

    Abstract : Ethanol produced from cellulose is a promising future alternative fuel. The production process has three main steps: (i) pretreatment of raw material to increase degradability; (ii) enzymatic hydrolysis of cellulose to produce glucose; (iii) fermentation of glucose into bioethanol.

  5. 23. The Pancreatic Tumour Microenvironment. Influence by macrophages and glucose levels on tumourigenesis

    Author : Emelie Karnevi; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Pancreatic cancer is the fourth cause of cancer-related death with a 5-year survival rate less than 5%. Two of the risk factors are chronic pancreatitis and type 2 diabetes (T2D), which are believed to promote the tumour progression. READ MORE

  6. 24. Regulation of exocytosis by Ca2+ and cAMP - A study on pancreatic beta- and alpha-cells

    Author : Xiaosong Ma; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Endocrinology; secreting systems; type-2 diabetes; SUR1; Ca2 -channel; glucagon; exocytosis; insulin; diabetology; Endokrinologi; sekretion; diabetologi;

    Abstract : Type-2 diabetes is characterized by impaired insulin secretion associated with excess glucagon release. Exocytosis of insulin- or glucagon-containing granules is initiated by Ca2+-influx through voltage-dependent Ca2+-channels and is modulated by the second messengers such as cAMP. READ MORE

  7. 25. Incretin Hormone Secretion - Studies in Human Subjects

    Author : Ola Lindgren; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin; obesity; GLP-1; GIP; incretin;

    Abstract : Several different hormones are released from the intestine following a meal. In this thesis we have focused on the so called incretin hormones, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). READ MORE
