Preventing Tuberculosis Reactivation
Tuberculosis (TB) is the leading cause of death due to infectious disease in the world today.
It is estimated that 2 billion people are currently infected, and although most people have latent infection, reactivation can occur. This paper by Denise Kirschner and colleagues, publishing in PLoS Computational Biology, conducts virtual clinical trials to examine the causes of reactivation.
Tumor necrosis factor alpha (TNF) is a protein that facilitates cell–cell communication during an inflammatory immune response. Animal models have shown that TNF is vital for control of TB infection. However, anti-TNF treatments are common therapies for treating autoimmune diseases, and this can cause an unwanted side effect of reactivating latent TB. Kirschner has developed a computational model that can quickly perform virtual clinical trials to predict why reactivation occurs and why it happens differently with different drugs.
Their results suggest that anti-TNF therapy is highly likely to lead to many incidents of TB if used in areas where exposure to the TB pathogen is probable. However, they also propose that a TNF-modulating agent could be developed that could balance the requirement for reduction of inflammation with the necessity to maintain resistance to infection and microbial disease. In the mean time, modifying the dosage and timing of anti-TNF treatment could prevent reactivation, as could a complete regimen of antibiotic treatment for TB prior to anti-TNF treatment.

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...
