1. Formation and repair of complex DNA damage induced by ionizing radiation
Abstract : DNA is the critical target when cells are exposed to ionizing radiation, a potent stressor with capacity to produce complex DNA damages, thereby increasing the risk of cancer. DNA and associated histones form chromatin, which is an effective protection against ionizing radiation. READ MORE

2. Induction and repair of clustered DNA damage sites after exposure to ionizing radiation
Abstract : The mechanisms that maintain genomic stability safeguard cells from constant DNA damage produced by endogenous and external stressors. Therefore, this thesis aimed to specifically address questions regarding the requirement and involvement of DNA repair proteins in the repair of various types of radiation-induced DNA damage.

3. Radiation response in human cells : DNA damage formation, repair and signaling
Abstract : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. READ MORE

4. Inventory strategies for monitoring and evaluation of forest damage
Abstract : Under global change, increasing stresses on forests require strategies for monitoring and mitigation of damages caused by pests and diseases. While the threats to forests increase, so do the possibilities to set up efficient monitoring programmes and detect forest damage by utilising new technologies. READ MORE

5. Role of Non-Homologous End-Joining in Repair of Radiation-Induced DNA Double-Strand Breaks
Abstract : Efficient and correct repair of DNA damage, especially DNA double-strand breaks (DSBs), is vital for the survival of individual cells and organisms. Defects in the DNA repair may lead to cell death or genomic instability and development of cancer. READ MORE
