  2. 11. Surface reactions on mineral particles controlling the hydrolysis of glucose phosphates

    Author : Rickard Olsson; Per Persson; Reiner Giesler; Dean L. Hesterberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi;

    Abstract : Phosphorus (P) is an essential nutrient. A significant amount of soil P may be in the form of organophosphates. Due to the size of these compounds, hydrolysis is often required before P can be assimilated by organisms. Hydrolysis may be mediated by mineral surfaces, or catalyzed by extra cellular enzymes.

    Abstract : Phosphorus (P) is an essential element for life on our planet. It is central in numerous biochemical processes in terrestrial and aqueous ecosystems including food production; and it is the primary growth-limiting nutrient in some of the world’s biomes. READ MORE

  7. 15. Aspects of Regulation of GFR and Tubular Function in the Diabetic Kidney : Roles of Adenosine, Nitric Oxide and Oxidative Stress

    Author : Patrik Persson; Fredrik Palm; Peter Hansell; Bengt Rippe; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes; diabetic nephropathy; glomerular filtration rate; renal blood flow; insulin; renal hemodynamics; micropuncture; oxygen; NADPH-oxidase; apocynin; streptozotocin; l-arginine; CGS21680; rats; mice; Physiology; Fysiologi; Medical Science; Medicinsk vetenskap;

    Abstract : Diabetic nephropathy is the main cause for initiation of renal replacement therapy and early symptoms in patients include increased glomerular filtration rate (GFR), decreased oxygen tension and albuminuria, followed by a progressive decline in GFR and loss of kidney function. Experimental models of diabetes display increased GFR, decreased tissue oxygenation and nitric oxide bioavailability. READ MORE
