Scientists figured out how to highlight the places of accumulation of calcium in the body

Russian chemists in cooperation with German colleagues have synthesized compounds that are able to highlight the contrast with the calcium ions in solutions, biological tissues and even within cells. The method will find application in the treatment of bone diseases and in non-invasive diagnosis of different tumors associated with excess risk of soft tissue calcification. Description of the development published in the journal Sensors and Actuators B: Chemical.

The study was conducted by staff of the Department of chemistry and technology of biomedical preparations RCTU named after D. I. Mendeleev, in cooperation with the Institute of gene biology of RAS, Institute General physics of RAS, as well as the Technical University of Chemnitz and the University of Erlangen-Nuremberg in Germany. The work is executed at support of Russian science Foundation grant.

Scientists have created a personalized drug from Scorpion venom

Russian scientists together with colleagues from Belgium with a substance — a prototype of personalized drugs against autoimmune diseases and cancer. The study is published in the journal Frontiers in Pharmacology.

The basis was taken the poison motley Scorpion Mesobuthus eupeus, can block potassium channels "gateway" for potassium ions across the cell membrane. These are essential to every cell elements are involved in many cellular processes, such as conducting nerve impulses, cell division and their interactions with each other, as well as in the immune response.

Russian scientists are "astrobotnia" vascular prostheses

Specialists of the research Institute for complex issues of cardiovascular diseases (NII KPSS, Kemerovo) made a new practical step towards the creation of cardiovascular prostheses of small diameter, which, when implanted in a living organism would not present a risk of blood clots, scientists were able to show the relative efficiency they created a vascular prostheses on large laboratory animals, reported the press service of the Institute.

Synthetic vascular prostheses interact with the blood and the surrounding tissues and soon after implantation, are covered with blood clots, which poses a threat to the health and lives of patients. So you want to create such an artificial vascular prosthesis which minimally would contribute to blood clot formation.

Scientists have figured out how to look close to jets of quasars

Astrophysicists from Russia, Germany, Finland and the US studied more than 300 quasars and rotating black holes, of which the "beat" of hot plasma jets, and found that these emissions change their shape when removed from the centre. The study is published in the journal Monthly Notices of the Royal Astronomical Society.

Quasars are among the brightest objects in the cosmos. Due to its extreme remoteness of the quasars considered fixed points and measure the Earth rotation parameters and coordinates of points on its surface. Therefore it is very important know the nature of their glow.

Butter found pathogenic bacteria

Russian scientists first read the genome of microbes in butter of different brands and found a number of opportunistic species, including dangerous for children. The study is published in the journal Foods.

Dairy products — the excellent environment for the growth of many dangerous bacteria, e.g. Salmonella. In Russia, the product quality according to established Standards, but even at observance of all norms of production, to ensure the absence of microbial contamination is impossible, as it often happens that the microorganisms can be detected only with the involvement of the latest scientific methods.
