16. Role of oxidative stress response in radiosensitivity
Sammanfattning : The quality of the ionizing radiation (IR) can be described in terms of its nature, photons or particles, and their corresponding energies. The energy is classified in terms of High or Low linear energy transfer that will produce a different distribution of DNA damage and other molecules in the cell either by direct action or indirect action.

17. Thin metal films on weakly-interacting substrates : Nanoscale growth dynamics, stress generation, and morphology manipulation
Sammanfattning : Vapor-based growth of thin metal films with controlled morphology on weakly-interacting substrates (WIS), including oxides and van der Waals materials, is essential for the fabrication of multifunctional metal contacts in a wide array of optoelectronic devices. Achieving this entails a great challenge, since weak film/substrate interactions yield a pronounced and uncontrolled 3D morphology. LÄS MER
18. Oxidative stress and alterations in the mammalian iron metabolism : A study on iron, inflammation, oxidative stress and neurodegeneration
Sammanfattning : Iron is essential for all living organisms, from bacteria to man for a broad variety of biological functions, including oxygen transport and DNA synthesis. However, iron can also be toxic, due to its involvement in the formation of highly reactive oxygen species through Fenton chemistry. LÄS MER
19. Redox Regulation and Stress Responses - Studies in Bacillus subtilis
Sammanfattning : Redox reactions are central to all organisms to sustain life. Both anabolic and catabolic metabolism depends on them. It is thus vital to sense and adjust the redox balance in the cell. One major factor affecting the redox status is the level of oxygen present. LÄS MER
20. Insulin-Producing Cells, Iron, Oxidative Stress, and Lysosomal Pathology
Sammanfattning : Accumulating evidence suggests that injnries caused by oxygen-derived radicals contribute to the destruction of pancreatic islet ß-cells in autoinnnune diabetes mellitus (diabetes type I, or IDDM). Oxidative stress may be caused by an enhanced production of oxygen-derived radicals, or by a decreased scavenging of such molecules. LÄS MER
