Evaluation of the diagnostic criteria for anti-NMDA receptor encephalitis in children

Tokyo, Japan - Materials in a glassy state are everywhere in our lives and have contributed to humanity for many years. Today, they play a critical role in various technologies, including optical fibers. Although we believe that glass is highly stable, it sometimes crystallizes, resulting in loss of transparency and isotropy, essential characteristics of glass, which has been a significant problem in industrial applications. The reason why crystallization occurs in a solid-state with almost no molecular movement has been a great mystery. Its understanding may help to prevent or optimize crystal growth at deep supercooling. In a study recently published in Nature Materials, researchers ...

A dengue virus vaccine candidate has passed an important milestone, with promising results in animal model testing providing hope to the 390 million people infected every year. The University of Queensland-developed vaccine candidate, applied to the skin via the high-density microarray patch (HD-MAP), has produced a protective immune response in dengue-infected mice. UQ PhD candidate Jovin Choo said the result could lead to a readily administered vaccine that could help halt the devastation of dengue fever globally. "Dengue is the most significant mosquito-borne viral disease in the world's ...

LOS ALAMOS, N.M., May 12, 2021--A new theorem from the field of quantum machine learning has poked a major hole in the accepted understanding about information scrambling. "Our theorem implies that we are not going to be able to use quantum machine learning to learn typical random or chaotic processes, such as black holes. In this sense, it places a fundamental limit on the learnability of unknown processes," said Zoe Holmes, a post-doc at Los Alamos National Laboratory and coauthor of the paper describing the work published today in Physical Review Letters. "Thankfully, because most physically interesting processes are sufficiently simple or structured so that they do not resemble ...

A new study, by researchers from Simon Fraser University and the Department of Fisheries and Oceans, reveals the trade-offs of fish biodiversity--its costs and benefits to mixed-stock fisheries--and points to a potential way to harness the benefits while avoiding costs to fishery performance. Many Pacific salmon fisheries catch fish that come from multiple stocks (management units), often representing locally-adapted populations, in so-called mixed-stock fisheries. Fish are intercepted in the ocean as they migrate along the coast, returning to different rivers to spawn. The study used computer models of hypothetical fisheries and case studies of three actual sockeye salmon fisheries, including BC's Fraser River fishery, to explore how fish biodiversity within mixed-stock ...

PASADENA, Calif. -- Among cancer patients with health coverage in Southern California, those who were diagnosed and treated at Kaiser Permanente, an integrated health care organization, had better survival rates, especially Black and Latino patients, according to Kaiser Permanente research published in The American Journal of Managed Care. "Kaiser Permanente is committed to finding and addressing health care inequities," said the study's senior author, Reina Haque, PhD, a cancer epidemiologist in the Kaiser Permanente Southern California Department of Research & Evaluation. "We investigated survival among insured patients with cancer ...

SAN FRANCISCO, CA--May 12, 2021--Following the minuscule movements of every cell in a petri dish would be a painstaking task for any human. But teach a set of computer programs to do the job, and they can complete it quickly and even observe things that the human eye would miss. Scientists at Gladstone Institutes have developed such an approach, which uses "neural nets"--artificial intelligence programs that can detect patterns--to analyze the locations of hundreds of cells growing together in a colony. When they applied the technique to a group of stem cells, the program revealed that a small number of cells act as "leaders," able to direct the movements of their neighbors. "This technique gives us a much more comprehensive view of how cells behave, how they work cooperatively, and how ...

White evangelicals are best persuaded to mask up through messages that stress the Christian doctrine of "love thy neighbor," according to a UCR-authored study published Tuesday. The study yielded a second effective way to persuade white evangelicals - but only if they are Republican. That is, messaging from former President Donald Trump that aligns mask-wearing with patriotism. The lessons learned from the study can be borrowed for pro-vaccine messaging, said study author Jennifer Merolla, a UCR professor of political science. About 45% of white evangelicals do not plan on getting vaccinated against COVID-19, according to a Pew Research Center poll. Health officials have said persuading the 41 million white evangelical ...

A person's stance on abortion is linked to their, often inaccurate, belief about when a fetus can feel pain, a University of Otago study has found. Lead author Emma Harcourt, PhD candidate in Otago's Centre for Science Communication, says misinformation about abortion and pregnancy is common and potentially harmful. "The current medical consensus is that it is unlikely that fetal pain perception is possible before the 29th or 30th weeks of pregnancy. However, we found that most people believe that the capacity to feel pain develops much earlier and that this was particularly evident in participants with anti-abortion views," she says. The study, published in The Australian and New Zealand Journal of Obstetrics and Gynaecology, recruited 374 ...

Numerous compelling evidences from astroparticle physics and cosmology indicate that the major matter component in the Universe is dark matter, accounting for about 85% with the remaining 15% is the ordinary matter. Nevertheless, people still know little about the dark matter, including its mass and other properties. Many models predict dark matter particles could couple to ordinary particle at weak interaction level, so it is possible to capture the signal of dark matter particle in the direct detection experiment. The scientific goals of the China ...

The evolution of ankle and foot bones into different shapes and sizes helped mammals adapt and thrive after the extinction of the dinosaurs, a study suggests. A surge of evolution following the mass extinction 66 million years ago enabled mammals to diversify and prosper during a period of major global change, researchers say. Analysis of bones that form part of the ankle and the heel of the foot reveal that mammals during this time - the Paleocene Period - were less primitive than previously thought. Palaeontologists from the University of Edinburgh made the discovery by comparing the anatomy of Paleocene mammals with species from the earlier Cretaceous ...
