Hepatitis C Virus (HCV), as a major agent of non-A, non-B hepatitis (NANBH), has been described as an insidious disease and a silent epidemic, mainly because the infection is often sub-clinical. Acute infection is recognized in a minority of patients and in most cases the virus results in chronic infections taking 10-20 years before the emergence of liver disease. In the US, almost four million individuals are infected and up to 170 million worldwide.
An imbalance in helper T-cell type-1 (Th1) and type-2 (Th2) cytokines has been suggested as playing an important role in the cause of chronic viral infections, but this issue is not resolved in patients with hepatitis C virus (HCV) infection. Inflammation of the portal and portal areas is a common feature of chronic hepatitis C. Antigen presenting dendritic, or “tree-like,” cells are located in the portal area, and infiltrating T-cells are initially exposed to infected hepatocytes in the peripheral area. Thus, these areas could be sites of the initial processes of the immune response in chronic hepatitis C.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
