As some clinical studies had already outlined, stress is one of the most important causes of relapse observed in abstinent smokers. The study has revealed, in genetically-modified animals, that there is effectively a genetic predisposition to suffer more or less sensitivity to stress, and that this circumstance is capable of significantly modifying behaviour patterns, to the extent of inducing relapse in the craving for nicotine.
The study findings are included in the project “Vulnerability to nicotine addiction” which began in late 2004 and has the support of the National Institute on Drug Abuse (NIDA), part of the United States National Institutes of Health (NIH), that granted Rafael Maldonado one and a half million dollars (approximately 1,172,000 euros) to direct this ambitious project which has the participation of other European research groups, all of which are coordinated from the UPF.
Through the use of sophisticated genomic and behavioural analytical methods, the study has evaluated not only physical nicotine dependency but also affective manifestations and changes in behaviour caused by its presence in the body, such as states of anxiety, the craving to smoke or relapses after long periods of abstinence - this being one of the most innovative aspects of the study.
One of the aims of this project is to identify the neurobiological substrate underlying differences in individual vulnerability to nicotine addiction. Studies in genetically-modified mice show how nicotine affects the endogenous opiate system, the function of which in all mammals is to alleviate pain, increase positive emotions and provide pleasurable feelings. In short, the aim is to know more about the mechanisms involved in nicotine addiction that make us more prone to the habit of smoking.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
