  2. 1. On the Regulation of Ornithine Decarboxylase

    Author : Eva Lövkvist Wallström; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; Crithidia fasciculata.; polyamines; Ornithine decarboxylase; translational control; osmolarity; untranslated region; COS cells; CHO cells; transfection; protein turnover; PEST region;

    Abstract : The polyamines putrescine, spermidine and spermine have been shown to be involved in cell growth and differentiation, and are considered to be crucial components of the living cell. The synthesis of polyamines in the cell is strictly regulated. READ MORE

  4. 2. On Spectrum Sensing for Secondary Operation in Licensed Spectrum : Blind Sensing, Sensing Optimization and Traffic Modeling

    Author : Mohamed Hamid; Ben Slimane Slimane; Niclas Björsell; Octavia Dobre; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; Spectrum Sensing; Sensing Optimization; Blind Sensing; Traffic Modelling; Energy detection; Maximumum-minimum Eigenvalue Detection; Discriminant anlysis; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : There has been a recent explosive growth in mobile data consumption. This, in turn, imposes many challenges for mobile services providers and regulators in many aspects. One of these primary challenges is maintaining the radio spectrum to handle the current and upcoming expansion in mobile data traffic. READ MORE

  5. 3. Molecular regulation of rat histidine decarboxylase

    Author : Christine Dartsch; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physiology; omeprazole; antiserum; fetal rat liver; COS-7 cells; purification; bacterial expression; protein turnover; ECL cells; gastric mucosa; gastrin; histdine decarboxylase; histamine; Fysiologi; Proteins; enzymology; Proteiner; enzymologi;

    Abstract : Histamine is involved in a variety of physiological processes like gastric acid secretion, inflammation and neurotransmission. The production of histamine is catalysed by the enzyme histidine decarboxylase (HDC), which is a strongly regulated enzyme. READ MORE
