A new path for killing pathogenic bacteria

25/08/2016

Bacteria that cause tuberculosis, leprosy and other diseases, survive by switching between two different types of metabolism. EPFL scientists have now discovered that this switch is controlled by a mechanism that constantly adapts to meet the bacterium's survival needs, like a home's thermostat reacting to changes in temperature.

Progress in vaccination against vespid venom

25/08/2016

Especially in late summer, apprehension about wasp stings increases amongst allergy sufferers. So-called hyposensibilisation therapy can help, but it is linked to a heavy burden on patients and health insurers. Researchers at the Helmholtz Zentrum München and the Technical University Munich have now presented a method in the journal "Allergy", which facilitates a personalised procedure.

Drinking green tea to prevent artery explosion

24/08/2016

According to new research, green tea could prevent a deadly condition in the body's main artery. A Kyoto University team has found that abdominal aortic aneurysm - a condition in which the main artery becomes overstretched and bloated - developed less frequently in rats that drank green tea polyphenol, a major component of green tea.

Nanofiber scaffolds show new behaviour of stem and cancer cells

24/08/2016

A discovery in the field of biomaterials may open new frontiers in stem and cancer cell manipulation and associated advanced therapy development. Novel scaffolds are shown enabling cells to behave in a different but controlled way in vitro due to the presence of aligned, self-assembled ceramic nanofibers of an ultra-high anisotropy ratio augmented into graphene shells.

Gene therapy via ultrasound could offer new therapeutic tool

23/08/2016

Combining ultrasound energy and microbubbles to poke holes in cells may prove to be a new tool in the fight against cardiovascular disease and cancer, according to researchers from the University of Pittsburgh and UPMC. A study on this gene therapy approach, called sonoporation, is published in the Proceedings of the National Academy of Sciences (PNAS).

Yale study identifies how Zika virus infects the placenta

22/08/2016

In a new study, Yale researchers demonstrate Zika virus infection of cells derived from human placentas. The research provides insight into how Zika virus may be transmitted from expectant mother to fetus, resulting in infection of the fetal brain. The study was published online in JCI Insight.
