UGR researchers design an alternative to blood test to detect drugs in the body

22.06.2007
The presence of narcotic substances in a person’s body can usually be detected by a blood or urine test.

By means of a simple technique, doctors can say if someone is under the influence of a drug (through blood), if they have taken it within the last week (through urine) or if they usually take it (through the bile test). However, a research group of the department of Legal Medicine and Psychiatry of the University of Granada (Universidad de Granada [http://www.ugr.es]), coordinated by professor Antonio Hernández Jerez, has developed a new technique to obtain this information by testing the pericardial fluid.

The importance of his research lies in the multiple advantages of this fluid with regard to the others. Pericardial fluid is plasma ultrafiltered from the serous vessel surrounding the heart, a watertight compartment separated from blood. Blood analysis usually presents a problem: matrix interferences, such as red cells, proteins, fats, etc., which complicate this method.

The work, supervised by professor Hernández, has allowed to determine that the pericardial fluid is an alternative to test blood in order to carry out drug tests for forensic purposes, as it offers enough guarantees and presents a similar concentration of narcotic substances. One of the advantages highlighted by the professor of the UGR [http://www.ugr.es] is that this test is easier than blood test as it shows less interference and takes more time to decompose after the death of the person, which makes it possible to determine if the presence of drugs is connected with the death.

The research work, sponsored by the UGR, has been carried out with the collaboration of the Local Institute for Medical Research (IMIM) and the Spanish Institute of Toxicology of Barcelona, as a result of the doctoral thesis "Aplicación del líquido pericárdico al análisis de drogas de abuso en toxicología forense" (Application of the pericardial fluid to the testing of drugs of abuse in forensic toxicology) carried out by Teresa Contreras Montero.

The members of the department of Legal Medicine and Psychiatry of the UGR intend now to do research into alcohol consumption through certain metabolites present in the pericardial fluid, used as markers, in order to determine from a dead body if the person had consumed alcohol and if he was an alcoholic.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
