  1. 1. Solubility and polymorphism of molecular compounds

    Författare :Sandra Gracin; Åke C. Rasmuson; David J. W. Grant; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Chemical engineering; solubility; prediction of solubility; UNIFAC; activity coefficients; activity of the solid phase; polymorphism; controlled crystallization; sonication.; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : This thesis deals with the controlled crystallization of small organic molecules and is focused on solubility and polymorphism. The solubility was determined for phenylacetic acid, p-hydroxyphenylacetic acid, p-aminophenylacetic acid, p-hydroxybenzoic acid and ibuprofen in both water and in a range of organic solvents.

  2. 2. Functional characterisation of the CAG polymorphism in the androgen receptor- in vitro and in vivo

    Författare :Hannah Nenonen; Diabetes - öpatofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; androgen receptor; polymorphism; CAG polymorphism; androgen receptor activity; infertility; prostate cancer; androgen receptor function;

    Sammanfattning : The androgen receptor (AR) is the mediator of androgen actions. In the AR coding region there is a polymorphic CAG repeat encoding a stretch of the amino acid glutamine (Q). The repeat length modulates receptor activity and is normally distributed between 10-30 CAG with a median length of 22 repeats in white men. LÄS MER

  4. 4. Polymorphism and Crystallization of p-Aminobenzoic Acid

    Författare :Sandra Gracin; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; controlled crystallization; polymorphism; p-aminobenzoic acid;

    Sammanfattning : Polymorphs are solid phases where the chemical composition isequal but the crystal structure differs. Many organic compoundsmay appear in more than one crystalline structure. LÄS MER

  5. 5. The transferrin polymorphism : population genetics and associations with reproductive hazards and disease

    Författare :Carin Sikström; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Human serum transferrin (TF) carries iron from the intestine, reticuloendothelial system and liver parenchymal cells to proliferating cells in the body. TF is highly polymorphic, and previous findings of associations between TF types and reproductive hazards in different species suggest that the TF polymorphism may be involved in natural selection and susceptibility to disease.
