A study relates the neural damage provoked by Ecstasy with the ambient temperature at which it is consumed

06.08.2007
There exists a direct relationship between the consumption of MDMA, or Ecstasy, at a high ambient temperature and an increase in the neural damage which this drug provokes. This was the conclusion of the research carried out by Beatriz Goñi at the School of Pharmacy of the University of Navarra.

These results form part of her doctoral dissertation, entitled “A study of the neurotoxicity mechanism of 3.4-methylenedioxy-N-methylamphetamine (MDMA or ‘Ecstasy’) after its administration in rats: New responses to old questions.” By means of this study, the researcher was able to relate for the first time the body temperature of the user with a higher metabolism of this substance. There are two factors which, when they co-occurcan produce malignant hyperthermia, a disorder which can sometimes be fatal.

In order to come to this conclusion, the Pamplonan pharmaceutical specialist administered the drug to rats at ambient temperatures of 15, 21 and 30 degrees centigrade. After performing the pertinent analyses, she demonstrated that metabolism of Ecstasy is accelerated by higher ambient temperatures at the time of administration. In addition, higher ambient temperatures also increase, in the same proportion, the neurochemical deficit that affects the brains of the users of this drug.

Higher risk in closed establishments

According to Beatriz Goñi, the author of the study undertaken at the University of Navarra, the discoveries of this research project acquire more relevance precisely because Ecstasy is typically taken in closed environments, with lots of people and poor ventilation, due to which factors the temperature tends to be quite high.

In addition, she notes that the neural damage provoked by this substance, and which originally was only observed in rats, has already been demonstrated in humans, who appear to suffer severe damage to the serotoninergenic neurons, which are involved in processes as basic as sleep, appetite and mood regulation.

Finally, the pharmaceutical specialist noted that the damage caused by the consumption of MDMA is dependent upon its being metabolized after to its ingestion, since if it were administered directly to the brain, neuronal damage would not occur.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
