The female sex hormone oestrogen protects the structural stability of bones. To date, however, it had been unclear exactly which cells were involved in the hormone’s protective function in preventing changes in bone density. Researchers at Vetmeduni Vienna were able to show for the first time that oestrogen uses a certain cell type as a “mediator” for its beneficial effects on bone. When oestrogen binds to these so-called “bone lining cells”, which cover the bone surfaces, it regulates the expression of a protein called RANKL in these cells. Oestrogen deficiency leads to uncontrolled expression of RANKL, which can trigger pathological changes in the bones. Published in Scientific Reports.The most important female sex hormone, oestrogen, plays a crucial role in the regulation of bone mass.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...Powered by WPeMatico
