A careful study by a group of investigators of the University of Giessen suggests that there is no indication for mercury intoxication or amalgam allergy as a cause of somatic complaints.
To deepen the understanding of the numerous unspecific complaints which are related to the dental material amalgam both in patients and physicians, an interdisciplinary case-control study regarding toxicological, allergic, psychological and psychiatric aspects was conducted. Forty patients with amalgam-associated complaints were compared to a well-matched group of 40 amalgam bearers without complaints. Patients and controls underwent a dental examination, which included recording of the quantity, surface area and quality of amalgam fillings, a determination of the mercury load in blood and urine, an allergy examination including patch testing with amalgam and a psychometric assessment with questionnaires noting coping strategies (ABI-UMW-P), interpersonal problems (Inventory of Interpersonal Problems) and self-consciousness (SAM), the NEO Five-Factor Inventory, Symptom Checklist-90-R, Beck Depression Inventory and a screening instrument for somatoform disorders. Patients and controls did not differ with respect to mercury concentrations in body fluids. Only 1 patient was found to have a positive amalgam patch test; various other allergies could be determined in 28% of patients (n = 11). Patients had higher levels of psychic distress, a higher incidence of depression and somatization disorders as well as different styles of coping with anxiety compared to controls. No indication for mercury intoxication or amalgam allergy as a cause of the patients` complaints could be found. The theory of amalgam-related complaints as an expression of underlying psychic problems is supported. Treatment should focus on somatization and changing coping and attribution styles

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
