Hepatitis C is the most common cause of chronic viral infection in the Western World today. It affects an estimated 170 million people worldwide. It is a viral infection of the liver which is mainly transmitted through contact with contaminated blood or blood products.
Infant infection rates are also linked to the number of mothers infected with the viral infection and the risk factors associated with the transmission of the infection to their unborn children in the womb.
The results of a new 5-year study of 559 mother-child pairs in Ireland, one of the largest such studies of its kind, published in the American Journal of Obstetrics & Gynaecology, show that vaginal delivery and planned cesarean among mothers infected with Hepatitis C display almost equal transmission rates of Hepatitis C from mother to child (4.2% and 3% respectively).
“The mode of delivery itself was not shown to have a significant influence on the transmission rate of hepatitis C from mother to child,” says Professor Fionnuala McAuliffe from the National Maternity Hospital in Dublin and the School of Medicine and Medical Science at University College Dublin, one of the authors of the report.
“The main risk factor associated with the vertical transmission of hepatitis C was the presence of detectable hepatitis C virus in the mother’s bloodstream, a condition where viruses enter the bloodstream and hence have access to the rest of the body.”
“Mothers who demonstrated detectable hepatitis C virus had a significantly higher transmission rate (7.1%) to their infants compared to the transmission rate (0%) for those in whom the hepatitis C virus was undetectable during pregnancy,” explains Professor McAuliffe.
“According to these new findings, if the Hepatitis C virus is undetectable antenatally despite the mother being antibody positive the patient can be reassured that the risk of vertical transmission to their child is minimal, and this is a significant development for patient counseling.”

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
