Using such knowledge and maslinic acid isolation from olive remains by scientists of the Department of Organic Chemistry of the UGR [http://www.ugr.es], they started to do research into the growth possibilities of this compound, which works as a serin protease inhibitor, for fishes like rainbow trouts. Results are clear: fishes whose diets are complemented with maslinic acid grow bigger and sooner, and fewer of them die. It has been observed that these animals live better, that their scales and fins look better and that the normal death rate in fish farms, between 5 and 10%, reduces almost to zero.
Despite a lot of additives work as toxins in some species, maslinic acid has worked quite the opposite in rainbow trouts. Cells of these animals get better structured if they are supplied with this compound; its application in animal feeding is already waiting for its patent at international level.
Experiments have gone on for 225 days in 3 consecutive years to observe the growth process of fishes. In all, between three thousand and five hundred and four thousand animals have been studied, with an initial weight of 20 grams, especially brought from the fish farm for the study. Its growth and development is observed in five experimental groups, which are supplied with five types of doses: 1, 5, 25, 50, 100 and 250 miligrams for each kilogram of diet.
Fight against AIDS
Maslinic acid is a pentacyclic terpenic with antioxidant and anti-cancer effects which could have possitive consequences in the fight against AIDS; they are being studied in the Institute Carlos III under the supervision of Professor Vallejo Nájera. Currently, the group of Professor Lupiáñez Cara is working on anti-cancer effects of maslinic acid. To this end, it is necessary to go deeply into pharmacodynamic research, and into the selective capacity of this compound to inhibit cell apoptosis, this is, interruption of the planned cell death that caused by cancer.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
