The project also identifies proteins in the mouth that seem to be coming from outside of salivary glands, from places such as epithelial tissues or blood.. stress sensing epidermal sensor -Rogers Group developed a multifunctional skin-mounted microfluidic device that is able to measure stress in people in multiple ways. prior teams have developed skin-adhesive devices that that collect sweat samples. The tiny samples contain small amounts of cortisol, a hormone that can be used as a marker of stress levels. In this new effort, the researchers have improved on these devices by developing one th.. pH dependent binding site transition of enzyme All biological processes are in some way pH-dependent. Human bodies and those of other organisms need to maintain specific and constant pH regulation in order to function. Changes in pH can have serious biological consequences—or serious benefits. Cellulosomes are extracellular complexes consisting of multiple enzymes, which are associated with the cell's surface. Within the cellulosome cellular.. sensor that capture facial expression by strain difference & ML People with amyotrophic lateral sclerosis (ALS) suffer from a gradual decline in their ability to control their muscles. As a result, they often lose the ability to speak, making it difficult to communicate with others. A team of MIT researchers has now designed a stretchable, skin-like device that can be attached to a patient's face and can measure small movements such as a twitch or a smile. T.. do fish school reduce energy cost of swimming? Do fish save energy by swimming in schools? Now, scientists from the Max Planck Institute of Animal Behavior (MPI-AB), the University of Konstanz, and Peking University have provided an answer that has long been suspected but never conclusively supported by experiments: yes. Using biomimetic fish-like robots, the researchers show that fish could take advantage of the swirls of water generated by.. detecting IL-6 for COVID, using surface coating which repel other molecule. When COVID-19 attacks, the immune system produces a cytokine, or protein, called Interleukin-6 (IL-6), whose concentrations can offer vital information about a patient's level and stage of infection. But measuring the critical marker has been extremely challenging, given its nearly undetectable presence in the biological stew that makes up human blood. Existing technology has not been accurate o.. electronically detecting cancer biomarker (antibody) A user would mix a droplet of blood in a vial of reactive liquid, then place the mixture onto a strip and insert it into a reader. In minutes, the device would measure an antigen that indicates the degree to which cancer is present. The prototype has been designed to monitor prostate specific antigen (PSA) and the technology can readily be adapted to measure other markers, depending on the form .. deviation from traditional diet causing disease Are obesity, diabetes, cardiovascular illnesses and more the result of a "mismatch" between the meals we eat and the foods our bodies are prepared for? The "mismatch hypothesis" argues that each of our bodies has evolved and adapted to digest the foods that our ancestors ate, and that human bodies will struggle and largely fail to metabolize a radically new set of foods. "No one diet is universa.. 이전 1 2 3 4 ··· 19 다음
