  1. 31. Antiapoptotic effect of ouabain in renal cells exposed to toxic glucose levels

    Författare :Liang Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Diabetes mellitus is a group of metabolic diseases that causes enormous social and economic burden. The kidney is the filtration organ that produces urine and is the primary target of diabetic complications, a condition called diabetic nephropathy (DN). LÄS MER

  3. 32. Solar-based physicochemical-biological processes for the treatment of toxic and recalcitrant effluents

    Författare :Tamer Essam; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; combined process; biodegradaiton; phenolics; phenol; Advanced Oxidation Processes; Photodegradation; photolysis;

    Sammanfattning : Wastewater treatment is a worldwide necessity that is even more crucial to countries deprived from abundant fresh water sources or unable to afford advanced and costly processes. With this perspective, this thesis was conducted within an Egyptian-Swedish research collaboration that aimed to develop solar-based (as free renewable energy source available locally) process for hazardous wastewater treatment.

    Sammanfattning : Micropollutants in water are biological or chemical contaminants that are present in ground and surface waters in trace quantities. They are a result of human activity and include pharmaceutically active compounds (PhACs) and endocrine disrupting compounds (EDCs). LÄS MER

  5. 34. In vitro models to study mechanisms of neural cell death induced by toxic agents

    Författare :Roshan Tofighi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neurotoxicity arises when exposure to toxic agents, either naturally occurring or manmade substances, alters the normal activity and/or structure of the nervous system. This can lead to disruption of vital metabolic processes and eventually to cell death. Certain unique features of the nervous system make it particularly vunerable to toxicants, e. LÄS MER

  7. 35. Lead-free Metal Halide based Solar Cells

    Författare :Huimin Zhu; Erik Johansson; Gerrit Boschloo; Feng Gao; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Low-toxicity; emerging light harvesters; lead-free; low toxic bismuth; Ag Cs -Bi Sb -I Br systems; 2D perovskites.;

    Sammanfattning : Lead-halide perovskites have recently appeared as very promising materials for solar cells. However, their stability and toxicity may be limiting factors for their application. Therefore, to find new low toxic and high stability light harvesters may be necessary for overcoming the challenges of perovskite solar cells. LÄS MER
