  2. 1. Protein stabilization. Some methods and mechanisms

    Author : Maria Andersson; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorbitol; protein stability; preferential exclusion; polyol; poly-NIPAAm; polymer; poly ethyleneimine ; polyelectrolyte; oxidation; NMR spectroscopy; lysozyme; lactate dehydrogenase; fluorescence; dynamic light scattering; complex; additive; circular dichroism; stabilization; trypsin; thermo-reversible polymer.; Biotechnology; Bioteknik;

    Abstract : The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. READ MORE

    Abstract : The world’s increasing demand for energy and supplying this energy dominantlyfrom fossil fuels has a major impact on global climate change. Theenergy crisis has gotten more alarming in the recent years which increasedthe motivation for replacing fossil fuels with greener routes for energy harvest. READ MORE

  5. 3. Diabetes-induced Alterations in Renal Microcirculation and Metabolism

    Author : Fredrik Palm; Per Liss; Peter Hansell; Per-Ola Carlsson; Gerald DiBona; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; diabetes mellitus; kidney; nephropathy; oxygen tension; haemodynamic; nitric oxide; oxygen consumption; radical oxygen species; polyol pathway; Fysiologi; Physiology; Fysiologi;

    Abstract : Diabetes-induced renal complications, i.e. diabetes nephropathy, are a major cause of morbidity and mortality. The exact mechanism mediating the negative influence of hyperglycaemia on renal function is unclear, although several hypotheses have been postulated. READ MORE

  6. 4. Pathomechanism of diabetic nephropathy

    Author : Anna Körner; Karolinska Institutet; Karolinska Institutet; []
    Keywords : diabetic nephropathy; hyperflltration; Na ; K - ATPase; Dahl rats; salt sensitive hypertension; glomerulosclerosis; polyol pathway activation; oxidative stress;

    Abstract : Diabetic nephropathy is today the most common cause of end stage renal failure. The risk for developing overt diabetic nephropathy is considerably reduced by antihypertensive treatment, and adequate control of blood glucose. However, there is a need for additional and even more efficient tools to prevent this complication of diabetes. READ MORE

  7. 5. Synthesis and Characterization of Nanoprobes for X-Ray Fluorescence Computed Tomography (XFCT) Bio-imaging

    Author : Yuyang Li; Muhammet Toprak; Hans Hertz; Ender Suvaci; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : X-ray fluorescence computed tomography (XFCT) is an emerging biomedical imaging technique. The KTH-XFCT laboratory system offers a characteristic 24 keV emission line, and high spatial resolution (200 ?m) images. XFCT as a newly emerging modality also requires the exploration and development of suitable contrast agents. READ MORE
