  1. 21. Transformation of Micropollutants in the Hyporheic Zone

    Författare :Malte Posselt; Jonathan P. Benskin; Michael Radke; Merle Plassmann; Magnus Breitholtz; Ian Cousins; Gudrun Massmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; micropollutants; hyporheic zone; biodegradation; bacteria; pharmaceuticals; transformation products; LC-MS MS; macrophytes; bedforms; suspect screening; mesocosm; flume; river; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Hyporheic zones (HZs) are reactive transition regions between rivers and aquifers which are thought to play an important role in the attenuation of micropollutants. Micropollutants are chemical substances such as pharmaceuticals, industrial chemicals or personal care products that are found in trace concentrations in the environment and that can be harmful to organisms.

  3. 22. Adsorption and transformation of organic micropollutants in wastewater : New insights from 14C-labeling

    Författare :Alexander Betsholtz; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated carbon; ozonation; Organic micropollutants; pharmaceuticals; wastewater; transformation products; biological degradation; GAC-filters; adsorption; 14C-labeling;

    Sammanfattning : This thesis focuses on the removal of organic micropollutants and transformation products using ozone and activated carbon treatment processes. A combination of 14C-labeled and non-radiolabeled organic micropollutants was used to study aspects of micropollutant removal from novel perspectives. LÄS MER

  4. 23. Chiral Separation of Amines by Non-Aqueous Capillary Electrophoresis using Low Molecular Weight Selectors

    Författare :Ylva Hedeland; Curt Pettersson; Ulf Bondesson; Lars Blomberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pharmaceutical chemistry; Chiral Separation; Non-Aqueous Capillary Electrophoresis; Enantioresolution; Electro-osmotic Flow; Pharmaceuticals; Enantiomeric Amines; Low Molecular Weight Selector; Farmaceutisk kemi; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Sammanfattning : Three chiral selectors (diketogulonic acid, benzoxycarbonylglycylproline and ketopinic acid) have been introduced for enantioseparation of pharmacologically active amines in non-aqueous capillary electrophoresis. The use of organic solvents, instead of aqueous buffers in the background electrolyte facilitated ion-pair formation between the analytes and the chiral selectors. LÄS MER

  5. 24. Tamiflu® - Use It and Lose It?

    Författare :Josef D. Järhult; Björn Olsen; Hanna Söderström; Jonas Waldenström; Robert G. Webster; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; influenza; oseltamivir; Tamiflu; resistance development; H274Y; environment; pharmaceuticals; mallard; dabbling duck; avian influenza; influensa; resistensutveckling; miljö; läkemedel; gräsand; Infektionssjukdomar; Infectious Diseases;

    Sammanfattning : Influenza A viruses cause seasonal and pandemic outbreaks that range from mild infections to the disastrous Spanish Flu. Resistance to neuraminidase inhibitors (NAIs) is a growing problem as these drugs constitute a vital part of treatment strategies and pandemic preparedness plans worldwide. Oseltamivir (Tamiflu®) is the mostly used NAI. LÄS MER

  7. 25. Translating Foreign Ideas into Domestic Practices : Pharmaceutical Policies in Laos and Vietnam

    Författare :Kristina Jönsson; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political and administrative sciences; goal-means rationality.; logic of appropriateness; logic of consequentiality; implementation; policy formulation; transmission dynamics; globalisation; pharmaceuticals; NDP; National Drug Policy; Vietnam; Translation; Laos; policy diffusion; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Statsvetenskap; förvaltningskunskap; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : Similar policies may be found in different countries. This, in turn, is an indication that policies travel. LÄS MER
