1. The oxidative stress response of Francisella tularensis
Abstract : Francisella tularensis is capable of infecting numerous cell types, including professional phagocytes. Upon phagocytosis, F. tularensis resides within the phagosome before escaping into the cytosol to replicate. Phagocytes constitute a hostile environment rich in ROS, which are employed as a means of killing pathogens. READ MORE

2. Oxidative stress and alterations in the mammalian iron metabolism : A study on iron, inflammation, oxidative stress and neurodegeneration
Abstract : 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. READ MORE

3. Coordination of two different genomes in response to light and stress
Abstract : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. READ MORE

5. Heme Protein Biogenesis - Catalase in Enterococcus faecalis
Abstract : Heme proteins form a large and diverse group of proteins which are involved in a variety of biological functions. The heme prosthetic group enables them to carry out redox reactions, transport electrons, bind gaseous molecules, and function as sensors. Despite their importance only little is generally known about heme protein biogenesis. READ MORE
