E-Mail IMAGE: Low occlusal loading in malocclusion elicits neuroplastic changes in CMA and causes maladaptation of neuromuscular behavior in masticatory movements. Inset: A typical example of electromyographic activity with jaw movement patterns elicited. view more Credit: Department of Orthodontic Science,TMDU Tokyo, Japan - Incoming sensory information can affect the brain s structure, which may in turn affect the body s motor output. However, the specifics of this process are not always well understood. In a recent study published in Scientific Reports, researchers from Tokyo Medical and Dental University (TMDU) found that when young rats were fed a diet of either soft or regular food, these different sensory inputs led to differences in muscle control and electrical activity of the jaw when a specific chewing-related brain region was stimulated. ....
Scientists at Leipzig University, in collaboration with colleagues from Germany and England, have succeeded in reversibly slowing down cellular processes. A team of biophysicists led by Professor Josef Alfons Käs and Dr Jörg Schnauß were able to show in experiments that cells can be transferred into slow motion without changing the temperature. From a physical point of view, such possibilities have so far only been available in the context of the theory of relativity. ....
E-Mail IMAGE: The research team designs a simple, miniature electromechanical device for high-precision and real-time evaluations of deep tissue stiffness. view more Credit: Dr Yu Xinge s team By putting a piece of soft, strain-sensing sheet on the skin may be able to detect skin disorders non-invasively and in real-time very soon. A research team co-led by a scientist from City University of Hong Kong (CityU) has designed a simple electromechanical device that can be used for deep tissue pathology diagnosis, such as psoriasis, in an automated and non-invasive fashion. The findings will lay a foundation for future applications in the clinical evaluation of skin cancers and or dermatology diseases. ....
About 12,000 bacteria and viruses collected in a sampling from public transit systems and hospitals around the world from 2015 to 2017 had never before been identified, according to a study by the International MetaSUB Consortium, a global effort at tracking microbes that is led by Weill Cornell Medicine investigators. ....
E-Mail IMAGE: The T cell (yellow) touches the antigen-presenting cell. Tiny forces are applied on the surface, eventually the connection breaks. view more Credit: TU Wien / MedUni Wien T-cells play a central role in our immune system: by means of their so-called T-cell receptors (TCR) they make out dangerous invaders or cancer cells in the body and then trigger an immune reaction. On a molecular level, this recognition process is still not sufficiently understood. Intriguing observations have now been made by an interdisciplinary Viennese team of immunologists, biochemists and biophysicists. In a joint project funded by the Vienna Science and Technology Fund and the FWF, they investigated which mechanical processes take place when an antigen is recognized: As T cells move their TCRs pull on the antigen with a tiny force - about five pico-newtons (5 x 10-12 or 0.0000000005 newtons). This is not only sufficient to break the bonds between the TCRs and ....
