2. 1. Mitochondrial Iron Metabolism : Study of mitoferrin in Drosophila melanogaster

   Author : Christoph Metzendorf; Maria Lind Karlberg; Kenneth Söderhäll; Martina Muckenthaler; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; iron; Drosophila; mitochondria; mitoferrin; ferritin; spermatogenesis; cell cycle; DFO; MRS12; Cell and molecular biology; Cell- och molekylärbiologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

   Abstract : Iron has a dualistic character. On the one hand it is essential for the life of most organisms, on the other hand it is involved in the generation of reactive oxygen species that are implicated in diseases and aging. READ MORE

4. 2. Changed iron metabolism and iron toxicity in scrapie-infected neuroblastoma cells

   Author : Sandra Zetterström Fernaeus; Tiit Land; Gaetano Cairo; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prion disease; oxidative stress; iron metabolism; Neurochemistry; Neurokemi;

   Abstract : Reactions and interactions of iron and oxygen can be both beneficial and detrimental to cells and tissues. Iron is mainly found in our blood where it functions as a mediator in the transport of oxygen to the cells and is further vital for the cellular respiration reducing the oxygen to water. READ MORE

5. 3. Nutrition in the second year of life. Effects of different milk compositions on dietary intakes, growth and metabolism

   Author : Johan Svahn; Lund Pediatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein intake; nitrogen; iron fortification; iron intake; growth; fatty acids; fat metabolism; fat intake; energy intake; dietary intake; blood lipids; cow´s milk; cholesterol; Amino acids; children; protein metabolism.; Pediatrics; Pediatri;

   Abstract : In the diet for young children, whole cow´s milk is the major contributor of calories, protein and saturated fat, but it supplies little iron and polyunsaturated fat. Although several recommendations exist for the composition of formula, recommendations for the composition of milk for young children are lacking. READ MORE

6. 4. Degradation, Metabolism and Relaxation Properties of Iron Oxide Particles for Magnetic Resonance Imaging

   Author : Karen Briley Saebo; Håkan Ahlström; Atle Bjørnerud; Michael Knopp; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Magnetic Resonance Imaging; contrast agents; iron oxide particles; metabolism; relaxation mechanisms; Radiologisk forskning; Radiological research; Radiologisk forskning;

   Abstract : Whereas the effect of size and coating material on the pharmacokinetics and biodistribution of iron oxide based contrast agents are well documented, the effect of these parameters on liver metabolism has never been investigated. The primary purpose of this work was to evaluate the effect of iron oxide particle size and coating on the rate of liver clearance and particle degradation using a rat model. READ MORE

7. 5. Magnesium Chelatase: Insights into the first Step of Chlorophyll Biosynthesis

   Author : Nick Sirijovski; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron microscopy; Proteobacteria; Mutants; Rhodobacter capsulatus; Tetrapyrrole; Plant biochemistry; Växtbiokemi; Biochemistry; Metabolism; Biokemi; metabolism; Proteins; enzymologi; enzymology; Proteiner; Chlorophyll biosynthesis; AAA proteins; Magnesium chelatase; Barley; ATPase;

   Abstract : The enzyme magnesium chelatase inserts magnesium into protoporphyrin IX (Proto) to produce to magnesium protoporphyrin IX, the first unique intermediate of the chlorophyll biosynthetic pathway. Magnesium chelatase is composed of three distinct proteins termed I (molecular weight ~40 kDa), D (~70 kDa) and H (~140 kDa). READ MORE
