Overweight boys have greater increases in blood pressure in response to stress than their female peers and decreased ability to restore normal pressures, researchers say in the November issue of Hypertension.
A Medical College of Georgia study showed that, despite typically having a greater height/weight ratio, overweight girls’ blood pressures respond less to stress and their natural mechanisms for decreasing blood pressure work significantly better, said Dr. Gregory A. Harshfield, principal author.
"What we observed is that the boys had higher levels of blood pressure throughout, including during stress and recovery, but they did not show an equally greater level of sodium excretion to compensate for higher levels of blood pressure during stress," said Dr. Harshfield. "What we are showing is that the mechanisms driving salt-sensitive hypertension are having more impact in males than females," he said, noting that larger studies are needed before reaching any conclusions.

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...
