21. Oxidative mechanisms in London Familial Alzheimer´s disease and LPS-induced inflammation
Abstract : Alzheimer´s disease (AD) is the most common of the progressive neurodegenerative disorders and is characterized by the formation of Aβ deposits, neurofibrillary tangles and loss of neurons. Additional features of the disease are inflammation, increased oxidative stress and modified iron metabolism. READ MORE

22. Fractionation of Cu and Fe isotopes in metal-rich mine sites : biotic and abiotic processes
Abstract : After mineral exploitation the residual grinded and milled material, rich in sulphide minerals and heavy metals, is often left exposed to the atmospheric variables. This weathered mine waste material can lead to the formation of acid mine drainage (AMD) which has negative effects to the environment. READ MORE

23. Altered cell signaling linked to neurodegeneration : Studies on scrapie-infected neuroblastoma cells and activated microglia
Abstract : Prion diseases are neurodegenerative disorders that can affect humans and animals. The underlying event is a conformational change of the normal cellular prion protein (PrPC) into an aberrant isoform termed PrP-scrapie (PrPSc). PrPSc is thought to lead to neurodegeneration and activation of glial cells. READ MORE

24. Changed iron metabolism and iron toxicity in scrapie-infected neuroblastoma cells
Abstract : Reactions and interactions of iron and oxygen can be both beneficial and detrimental to cells and tissues. Iron is mainly found in our blood where it functions as a mediator in the transport of oxygen to the cells and is further vital for the cellular respiration reducing the oxygen to water. READ MORE
