  2. 1. Ecological impact of antibiotic treatment on human normal microflora

    Author : Mamun-Ur Rashid; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Ceftobiprole;

    Abstract : The skin and the mucosal surfaces of humans are colonized with microorganisms which are often referred as the normal microflora. There is a biological balance between the human host and the normal microflora in health. The extensive use of antibiotics in both humans and animals has caused the development of many resistant bacteria. READ MORE

  5. 3. Mechanisms of hedgehog signaling activation in cancer development

    Author : Mohammed Ferdous-Ur Rahman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Hedgehog (HH) signaling has an important role in many physiological processes, and deregulation of this pathway can result in a wide range of malignancies. The aim of this thesis is to identify and evaluate the role of various posttranscriptional mechanisms, including alternative splicing, RNA editing and antisense RNAs, associated with different key components of HH signaling.
