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.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
