1. 16. Anaemia and iron deficiency in children and women in Tanzania. Effects of dietary iron intake, low iron bioavailability and supplementation with multiple micronutrient beverage

   Författare :Simon Tatala; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; serum ferritin; haemoglobin; multiple micronutrient beverage; dietary iron intake; anaemia; serum retinol; iron deficiency; children and Tanzania; pregnant women; iron bioavailability;

   Sammanfattning : Anaemia was investigated in a rural Tanzanian community to determine its magnitude and causative factors in different population groups. Nutritional anaemia resulting mainly from a diet with a low bioavailability of iron affected more than half of the total number of women and children. LÄS MER

3. 17. Development of Second and Third Generation Bioelectronics

   Författare :Federico Tasca; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flow injection analysis; amperometric biosensor; mediated electron transfer; direct electron transfer; tryptophan repressor-binding protein; diaphorase; pyranose oxidase; cellobiose dehydrogenase; pyranose dehydrogenase; biofuel cell; spectroelectrochemistry; single wall carbon nanotubes; bioelectronics.;

   Sammanfattning : The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”.

4. 18. Characterisation of some iron proteins in Drosophilia melanogaster and Pacifastacus leniusculus

   Författare :Maria I. Lind; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk mykologi; Physiological Mycology;

   Sammanfattning : The cDNA cloning of the 76-kDa protein, an immune protein from crayfishhaemocytes, shows that it is similar to a family of haem-containing peroxidases.In addition to its cell adhesion activity it has also peroxidase activity, and theprotein was named peroxinectin. The cell adhesion is probably mediated by aKGD-motif present in peroxinectin. LÄS MER

5. 19. From Time-Averaged to Time-Resolved Crystallography: Studies on Superoxide Dismutase and Myoglobin

   Författare :Thomas Ursby; Lunds universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superoxide dismutase; Bayesian statistics; electron difference maps; synchrotron; docking site; photolysis; myoglobin; Time-resolved crystallography; Laue; thermostability; Sulfolobus solfataricus; Molecular biophysics; Molekylär biofysik;

   Sammanfattning : We have studied protein motions with nanosecond time-resolved crystallography. The release of carbon monoxide from its complex with myoglobin (MbCO) was triggered by nanosecond laser pulses. X-ray data were collected with time delays ranging from 4 ns to 1.9 ms using the Laue method, at the European Synchrotron Radiation Facility in Grenoble. LÄS MER

7. 20. An Ultrafast Spectroscopic and Quantum-Chemical Study of the Photochemistry of Bilirubin : Initial Processes in the Phototherapy for Neonatal Jaundice

   Författare :Burkhard Zietz; Tomas Gillbro; Jouko Korppi-Tommola; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bilirubin; Phototherapy; Neonatal Jaundice; Femtosecond Spectroscopy; CASSCF; TD-DFT; Isomerisation Dynamics; Biophysical chemistry; Biofysikalisk kemi;

   Sammanfattning : Bilirubin is a degradation product of haem, which is constantly formed in allmammals. Increased levels of bilirubin in humans lead to jaundice, a conditionthat is very common during the first days after birth. This neonataljaundice can routinely be treated by phototherapy without any serious sideeffects. LÄS MER
