  1. 1. Small RNAs in Phytophthora infestans and cross-talk with potato

    Författare :Sultana Jahan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Small RNAs (sRNAs) are small non-coding RNAs usually ranging in size 20-30 nt. They are playing important roles in plant-pathogen interactions. This thesis aimed at studying the sRNA populations in potato and Phytophthora infestans and their role in the potato-P. infestans interaction. LÄS MER

  3. 2. Statistical aspects of modeling panel data originating from smallholder household surveys in Sub-Saharan Africa and Vietnam

    Författare :Sultana Nasrin; Statistiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; power of test; endogeneity; multivariate; longitudinal data; diversification;

    Sammanfattning : This thesis focuses on multivariate multilevel modeling of panel data originated from smallholder farm surveys in Sub-Saharan African (SSA) countries and Vietnam to investigate driving forces in maize and rice production in SSA and diversification of farms in the rice sector in Vietnam. We also present and evaluate different tests for endogeneity in explanatory binary variables in multivariate linear regression models. LÄS MER

  4. 3. Mechanistic insights into the biosynthesis of polyketide antibiotics

    Författare :Azmiri Sultana; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Anthracyclines are a group of aromatic polyketide compounds with significant medical importance due to their antineoplastic properties. Doxorubicin and daunorubicin members of this family are among the two most commonly used anticancer drugs. However, these compounds exhibit severe side effects like cardiotoxicity and multi-drug resistance. LÄS MER

  5. 4. Device Fabrication and Photosensitizing Role of ZnO Nanostructures in Photodynamic Therapy of Cancer

    Författare :Kishwar Sultana; Magnus Willander; Omer Nour; Arne Rosén; Linköpings universitet; []
    Nyckelord :Zinc oxide nanostructures; light emitting diodes; reactive oxygen species; photosensitizer; cancer cell; photodynamic therapy; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : In nanoscience and nanotechnology, zinc oxide (ZnO) is gaining much research attention due to direct wide band gap (3.3 eV), large exciton binding energy (60 meV), and deep level defects emissions that cover the whole visible range. LÄS MER

  7. 5. Molecular and functional studies of interleukin-1a in the rat testis

    Författare :Taranum Sultana; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Interleukin-l alpha; spermatogenesis; Leydig cells; Sertoli cells; calpain I and II;

    Sammanfattning : The aim of the present study was to gain a better insight into the role of interleukin-1 alpha (IL-1 alpha) in testicular physiology. In testis, IL-1alpha acts as a paracrine mediator involved in the regulation of testicular functions. LÄS MER
