1. Regulation of proton-coupled electron transfer in cytochrome c oxidase : The role of membrane potential, proton pathways and ATP
Abstract : Cytochrome c oxidase (CytcO) is the final electron acceptor of the respiratory chain. In this chain a current of electrons, derived from degradation of nutrients, along with protons, are used to reduce oxygen to water. The reaction is exergonic and the excess energy is used to pump protons across the membrane. READ MORE

2. Sperm Membrane Channels, Receptors and Kinematics : Using boar spermatozoa for drug toxicity screening
Abstract : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. READ MORE

3. Interaction of Calcium Ions with Lipid Membranes
Abstract : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

4. Into the Membrane and Beyond : Improving Membrane Protein Over-Expression in Escherichia coli
Abstract : Membrane proteins fulfil a wide variety of essential functions in the cell and many are (potential) drug targets. Since their natural abundance is usually very low, most membrane proteins have to be over-expressed for functional and structural studies. READ MORE

5. Immersed flat-sheet membrane bioreactors for lignocellulosic bioethanol production
Abstract : The rising awareness of the environmental, economic and socio-political impacts of over-exploitation of fossil-based fuel and energy sources, have motivated the transition toward more sustainable and renewable energy sources. Lignocellulosic materials (e.g. READ MORE
