A compound from olive remains produces faster growth in trouts

09.10.2006
Mónica Fernández Navarro´s doctoral thesis, presented recently in the Department of Biochemistry and Molecular Biology of the University of Granada arises as a result of the teorethical research works of Professor José Antonio Lupiáñez Cara on molecular aspects and the protein manipulation in living organisms.

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.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
