By examining the tissues at a subcellular level, the researchers discovered yelloweye rockfish were able to immobilize several potentially toxic elements within their liver tissues (cadmium, lead, and arsenic) thus preventing them from interacting with sensitive parts of the cell. But mercury was found in concentrations known to be toxic - and most of it was in sensitive sites, such as mitochondria and enzymes, within liver cells.
A method for large-scale production of extracellular vesicles enriched with specific microRNAs (miRNAs) has been developed in the Wake Forest Institute for Regenerative Medicine (WFIRM) labs, offering a manufacturing standardization process which may have therapeutic applications and clinical impact.
A bacterial toxin that allows an infectious strain of bacteria to defeat its competitors has been discovered by Imperial College London scientists.
Researchers at the University of New Hampshire have created an easy-to-make, low-cost injectable hydrogel that could help wounds heal faster, especially for patients with compromised health issues.
Researchers have developed a model that predicts which of the viruses that can jump from animals to people can also be transmitted from person to person--and are therefore possible sources of human diseases.
In a paper published recently in the journal Origins of Life and Evolution of Biospheres, UW-Madison researchers described initial steps toward achieving chemistries that encode information in a variety of conditions that might mimic the environment of prehistoric Earth.
Tattoos are popular. Roughly one in eight Germans already has one. A recent representative survey conducted by the German Federal Institute for Risk Assessment (BfR) shows that many people consider tattoos to be safe to health, with almost 90 percent of people who already have a tattoo believing this to be the case. Few of them know that many tattoo inks have not yet been examined.
Angelman syndrome is a genetic disease with no cure. Children grow up with severe intellectual disabilities and a range of other problems, arguably the worst of which are epileptic seizures. Now scientists at the UNC School of Medicine have found evidence that genetic therapy may prevent the enhanced seizure susceptibility.
Scientists from ITMO University have proposed a new technology for creating optical micro-waveguides using inkjet printing. Using this method it is possible to quickly create waveguides with the necessary parameters without expensive equipment and complex procedures. The new technology is optimized for the production of optical elements on an industrial scale. The results are published in Advanced Optical Materials ?n 20th November 2018.
Researchers at the University of Helsinki have discovered a mechanism by which harmful tau protein aggregates are transmitted between neurons. Alongside amyloid plaques, tau aggregates in the brain are a significant factor in the progression of Alzheimer's disease.
