1. Constructing a timetable of autumn senescence in aspen
Abstract : During the development and lifecycle of multicellular organisms, cells have to die, and this occurs by a process called programmed cell death or PCD, which can be separated from necrosis or accidental cell death (Pennell and Lamb, 1997). Senescence is the terminal phase in the development of an organism, organ, tissue or cell, where nutrients are remobilized from the senescing parts of the plant into other parts, and the cells of the senescing organ or tissue undergo PCD if the process is not reversed in time.

2. To “leaf” or not to “leaf” : Understanding the metabolic adjustments associated with leaf senescence
Abstract : The adequate execution of the final developmental stage of a leaf, leaf senescence, is crucial to the long-term survival of the plant. During senescence cellular structures like membranes, proteins, lipids and macromolecules are degraded and released nutrients are relocated to developing parts of the plant, such as young leaves, stems, flowers, siliques and ultimately seeds that are dependent on this nutrient remobilization.

3. Identification and clinical evaluation of senescence-associated markers to distinguish melanocytic nevi from melanomas
Abstract : Melanoma is a form of cancer that develops in melanocytes. While it represents only 5% of skin malignancies, it is the most aggressive and lethal. Benign proliferation of these cells form the melanocytic nevi. The definitive diagnosis of melanocytic nevi or melanoma lesions is histopathologic. READ MORE

4. From green to yellow : a leaf story
Abstract : När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. READ MORE

5. Optimizing experimental radioimmunotherapy : investigating the different mechanisms behind radiation induced cell deaths
Abstract : Background. Radiation therapy is an important treatment regimen for malignant disease. Radiation therapy uses ionizing radiation to induce DNA damage in tumor cells in order to kill them. READ MORE
