Abstract The blazar TXS 0506+056 got into the spotlight of astrophysical community in 2017 September, when a high-energy neutrino detected by IceCube (IceCube-170922A) was associated at 3 ? level with ? -ray flare from this source. This multi-messenger photon-neutrino association remains, as per today, most significant ever observed. poorly studied object before IceCube-170922A event. To better...
High angular resolution images of extragalactic radio sources are being made with the Highly Advanced Laboratory for Communications and Astronomy (HALCA) satellite and ground-based radio telescopes as part of the Very Long Baseline Interferometry (VLBI) Space Observatory Programme (VSOP). VSOP observations at 1.6 and 5 gigahertz of the milli-arc-second-scale structure of radio quasars enable th...
Abstract Study question Is oxidative stress (OS) evaluated in human spermatozoa a predictive marker of better semen quality? Summary answer CellROX®Orange is new fluorescent probe able to detect Reactive Oxygen Species (ROS) identifying viable oxidized sperm fraction related performance. What known already OS, defined as an unbalance between ROS production and antioxidant defences, considered o...
The search for new producers of α-L-rhamnosidases and the study their properties are constantly carried out, which makes it possible to identify enzymes with unique properties. Thus, marine species microorganisms can radically differ in habitat conditions from terrestrial ones. Previously, we have isolated a number representatives Black Sea microbiota. However, results these studies did not all...
