1. Protection of Photosystem II from Photodamage during the Assembly of the Water Oxidizing Complex
Sammanfattning : Photosystem II catalyses the light driven oxidation of water, which is a key reaction in oxygenic photosynthesis. This enzyme is, however, exposed to light induced degradation, which decreases the efficiency of the photosynthetic process. LÄS MER
2. Exploiting chemical control in biomaterials
Sammanfattning : Chemistry and biology at the interphase will most likely give many of the answers to tomorrows medical challenges. Creating solutions to the problems at this interphase is benefiting from a collaborative research approach, driven by the need for development of chemistries or devices solving medical problems.

3. Ultraviolet light A (UVA) photoactivation of riboflavin as a potential therapy for infectious keratitis
Sammanfattning : .... LÄS MER
4. Paracrine control of glucagon secretion in the pancreatic α-cell: Studies involving optogenetic cell activation
Sammanfattning : ABSTRACT The mechanisms controlling glucagon secretion by α-cells in islets of Langerhans were studied. We generated mice with the light-activated ion channel ChR2 specifically expressed in β-, α-, and δ-cells, and explored the spatio-temporal relationship between cell activation and glucagon release.

5. Terahertz radiation as a pump and probe for studying low frequency vibrations in proteins
Sammanfattning : Many functionally important structural changes in proteins proceed along the direction of their lowest frequency vibrations. These vibrations correspond to picosecond collective dynamics. Establishing the fundamental relationship between these vibrations and protein function remains a challenge within biophysics. LÄS MER
