The light-sensitive layer found at the back of a person's eyes contains more than just cells that detect shadows and light — it also contains information about the health of a person's entire body. And now, artificial intelligence can glean this information from a single snapshot, new research suggests.
Medical researchers are increasingly turning to mobile devices such as smartphones and watches as a way to monitor patients in trials, an approach they hope improves participation and accuracy but that also has limitations.
Down's syndrome, also known as trisomy 21, is one of the most common genetic diseases. Researchers from the University of Geneva (UNIGE) and ETH Zurich (ETHZ), Switzerland, have recently analysed the proteins of individuals with trisomy 21 for the first time: the goal was to improve our understanding of how a supernumerary copy of chromosome 21 could affect human development. Published in the journal Nature Communications, the research shows that trisomy 21, far from only affecting the proteins encoded by the chromosome 21 genes, also impacts on the proteins encoded by the genes located on the other chromosomes.
The study, published December 5 in the Proceedings of the National Academy of Sciences, highlights the importance of vaccination for preventing the spread of HPV in young men before they become sexually active. Vaccination could potentially prevent reinfection in older men who have already contracted the virus.
As is well known, CRISPR/Cas9 is an effective tool for gene editing, and this method has been widely used for editing genes or genomic regions by targeting specific single-guide RNA (sgRNAs). We initially planned to use the CRISPR/Cas9 system to study the biological functions of Y chromosome genes.
People who experience frequent migraines may soon have access to a new class of drugs. In a pair of large studies, two drugs that tweak brain circuits involved in migraine each showed they could reduce the frequency of attacks without causing side effects, researchers report in the New England Journal of Medicine.
