6. Ammonia assimilation and nitrogen fixation in phototrophic bacteria : studies on glutamine synthease and the metabolic regulation of nitrogenase in Rhodospirillum rubrum
Abstract : The phototrophic bacteria and a few other species, are able to control nitrogen fixation on the metabolic level. This is a fast and reversible mechanism, which “switches off and on” the nitrogenase activity in response to the accessibility of combined nitrogen, the energy supply and the level of oxygen in the medium.

7. Glutathione metabolism of human skeletal muscle in surgical trauma
Abstract : Glutathione Metabolism of Human Skeletal Muscle in Surgical Trauma Jia-Li Luo Dissertation from the Department of Anesthesiology and Intensive Care, Huddinge University Hospital, KARO Institution, Karolinska Institutet. Stockholm, Sweden In man, muscle tissue serves as a protein reservoir which is mobilized to meet the specific metabolic needs associated with various catabolic conditions, such as surgical trauma and critical illness.

8. Proteomic profiles and gene expressions in the symbiotically competent cyanobacterium Nostoc sp. PCC 73102
Abstract : Nostoc PCC 73102 is an evolutionary important cyanobacterium with multiple phenotypic traits and symbiotic capacities. Based on two-dimensional gel electrophoresis (2-DE) and MALDI-TOF mass spectrometry, a proteomic approach was developed in order to obtain protein profiles of this symbiotically competent cyanobacterium during three trophic types/life stages: free-living photo-autotrophic and diazotrophic growth conditions, dark heterotrophic conditions and hormogonium formation.

9. The Round Window Membrane - Gateway to the Cochlea : A Morphological and Electrophysiological study
Abstract : Topical treatment of several inner ear diseases through the round window membrane (RWM) might be feasible in the near future. Bacteria toxins, ototoxic drugs and noise trauma seem to harm the inner ear by a common pathway which involves, excessive outflow of the afferent neurotransmitter glutamate and formation of nitric oxide (NO), which can severely damage cells/nerve endings and lead to cell death.

10. PII proteins as global regulators of bacterial nitrogen metabolism
Abstract : Nitrogen is an essential element to sustain life, being a component of most biological macromolecules. In spite of the abundance of gaseous N2, the availability of nitrogen compounds that can be readily used by most microorganisms is scarce and its production energetically demanding. READ MORE
