  2. 1. Second generation of Glucose Biosensors : Biofuel cells and Neurotransitters

    Author : NAJAT BEDEN; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GDH; PDH; GOx; CDH; mediated electron transfer MET; Os-polymer; Man-Os VI tmen; PVPOs II -Chitosan; Au-NPs-MWCNTS; enzymatic biosensors; non-enzymatic sensor; DA-sensor; Multi-analyte sensor; DA; AA; UA;

    Abstract : Different FAD dependent GDH enzymes together with the Os-redox polymer Os(4,4′-dimethyl-2,2′-bipyridine)2(PVI)10Cl]+ and a modified graphite electrode was shown to have distinct selectivity and high turnover rates towards glucose. The results of this study suggest that such electrodes may be applied either for glucose determination or as bioanodes in glucose biofuel cells. READ MORE

  4. 2. Caldicellulosiruptor Saccharolyticus: an Ideal Hydrogen Producer?

    Author : Sudhanshu Pawar; Avdelningen för kemiteknik; []
    Keywords : Caldicellulosiruptor owensensis; Caldicellulosiruptor saccharolyticus; hydrogen; volumetric hydrogen productivity; biofilm; osmotolerance; wheat straw hydrolysate; evolutionary engineering; CSTR; UA reactor and uracil auxotrophy;

    Abstract : Caldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. READ MORE

  5. 3. Experimental Studies of Ursolic Acid and Alkaline Sphingomyelinase in Colon Cancer and Colitis

    Author : David Andersson; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Sphingomyelin (SM) is a sphingolipid present in all eukaryotic cell membranes. Hydrolysis of SM by sphingomyelinase (SMase) generates ceramide, which has effects on cell-cycle regulation and apoptosis. READ MORE

  6. 4. Sensitivity and Uncertainty Analysis Methods : with Applications to a Road Traffic Emission Model

    Author : Olle Eriksson; Stig Danielsson; Rolf Sundberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission; Grid; Model; Pollutant; Response surface; Road traffic; Sensitivity analysis; Simulation; Uncertainty analysis; Avgaser; Vägtrafik; Miljöaspekter; Statistics; Statistik;

    Abstract : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. READ MORE

  7. 5. Dynamic Fetal and Placental Circulatory Changes during Uterine Contractions

    Author : Hui Li; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexualitet; reproduktion; andrologi; gynekologi; Obstetrik; sexuality; reproduction; andrology; gynaecology; Obstetrics; Venous; Uterine; Umbilical; Resistance; Pregnancy; Oxytocin; Labor; IUGR; Flow; Doppler; Contraction; Brain-sparing; Cerebral;

    Abstract : The best mode of delivery for fetuses with intrauterine growth restriction (IUGR) and umbilical artery (UA) blood flow changes is not well elucidated. Uterine artery, fetal UA, middle cerebral artery (MCA), and venous blood flow changes during uterine contractions during an oxytocin challenge test (OCT) have not been observed systemically. READ MORE
