  2. 1. Fate of Pharmaceuticals and Their Transformation Products in Rivers : An integration of target analysis and screening methods to study attenuation processes

    Author : Zhe Li; Anna Sobek; Michael McLachlan; Michael Radke; Kathrin Fenner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pharmaceuticals; transformation products; fate; river; suspect screening; non-target screening; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Pharmaceuticals are environmental contaminants causing steadily increasing concern due to their high usage, ubiquitous distribution in the aquatic environment, and potential to exert adverse effects on the ecosystems. After being discharged from wastewater treatment plants (WWTPs), pharmaceuticals can undergo transformation processes in surface waters, of which microbial degradation in river sediments is considered highly significant.

  4. 2. The global marine carbon system through time

    Author : Jenny Hieronymus; Jonas Nycander; Gösta Walin; Michael Follows; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Carbon dioxide is an important greenhouse gas and in order to understand its effect on the climate we need to identify its sources and sinks. This thesis focuses on different aspects of the marine carbon system and the exchange of carbon between the ocean and the atmosphere. READ MORE

  5. 3. Roles of mammalian Scribble in polarity signaling, virus offense and cell-fate determination

    Author : Michael Wigerius; Magnus Johansson; Lawrence Banks; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cell polarity; scribble; tbev; RhoGTPase; jak-stat; mapk; neurite outgrowth; influenza a virus; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Mammalian Scribble is a target for proteins encoded by human papilloma virus, retro- and flaviviruses. Tick-borne encephalitis virus (TBEV) is a flavivirus that have evolved distinct strategies to escape antiviral responses. READ MORE

  6. 4. A multi-tracer PET approach to study early-onset familial and sporadic Alzheimer's disease

    Author : Michael Schöll; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cumulated scientific evidence suggests that the pathology causing Alzheimer's disease (AD) occurs many years or even decades before memory impairment and other clinical symptoms arise. Tangible and detailed knowledge about different pathological processes, their interactions, and time course is therefore of the essence both for the development of potentially successful treatments and a reliable early diagnosis of this relentless disorder.

  7. 5. Development and repair of cataract induced by ultraviolet radiation

    Author : Ralph Michael; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ultraviolet radiation; cataract; forward light scattering; lens ultrastructure; refractive index; dose-response; repeated exposure; apoptosis; in vivo; rat;

    Abstract : Background: Several epidemiological investigations show a correlation between cataract development and the dose of ultraviolet radiation (UVR) received. It is experimentally well established that exposure of animal eyes to UVR induces cataract. Most cataracts develop as a gradual increase in lens opacity. READ MORE
