Nanoparticles, or tiny molecules that can deliver a payload of drug treatments and other agents, show great promise for treating cancers. Scientists can build them in various shapes with different materials, often as porous, crystal-like structures formed by a lattice of metal and organic compounds, or as capsules that enclose their contents inside a [...]
Just what is COVID capable of doing to the human brain? In a new study published in Molecular Psychiatry, researchers from Sweden and a Harvard-affiliated hospital in Boston tried to find out by creating “brain organoids,” or miniature brains about the size of a pinhead, and infected them with COVID. What they saw explained a lot: [...]
Researchers from the Université de Montréal in Canada have created and verified a new class of DNA-based drug transporters that are 20,000 times smaller than a human hair and could enhance cancer treatment and other diseases. Optimal Dosing at All Times: A Medical Challenge Providing and maintaining a therapeutic drug dosage during treatment is one of [...]
Article in Forbes by Steven Salzberg: After all the controversy over the past few years about gain-of-function research on viruses, especially the Covid-19 virus, I thought this kind of work was on hold, at least in the U.S. Indeed, the controversy grew so hot that NIH issued a statement in May of 2021 declaring that [...]
Cancer immunotherapies, such as immune checkpoint inhibition therapy, have been attracting attention in recent years as new methods for treating cancer. However, immune checkpoint inhibition therapy is only effective in 20%–30% of cancer patients, so developing better drug delivery systems to induce anticancer cellular immunity is necessary. A research group led by Associate Professor [...]
U.S. Centers for Disease Control and Prevention Director Rochelle Walensky has experienced a COVID rebound after a course of Paxlovid, the federal health agency announced Monday morning. Walensky, who initially tested positive for the virus on Oct. 21, completed a course of the COVID antiviral drug and eventually tested negative. But she tested [...]
Nanotechnology is expanding the ease of medical equipment access, information, and theranostics. Nanomedicine is the use of nanotechnology in medicine to provide efficient solutions for disease diagnosis, therapy, and prevention. In this article, AZoNano focuses on how nanomedicine is impacting society. Nanotechnology in Society Societies worldwide that lack access to fundamental services like clean water, [...]
A number of young children are being hospitalized because of respiratory syncytial virus, or RSV, and it’s happening at an unusual time of year and among older children than in years past. RSV infections and related emergency-room visits and hospitalizations are nearing seasonal peaks in some U.S. regions, according to the Centers for Disease [...]
The Omicron BA.5 subvariant is no longer the dominant cause of Covid-19 infections in the United States, according to estimates released Friday by the US Centers for Disease Control and Prevention. Instead, a host of new sublineages – offshoots of BA.2, BA.4 and BA.5 – are now responsible for the majority of new infections in this [...]
Scientists have shown that they can detect SARS-CoV-2, the virus that causes COVID-19, in the air by using a nanotechnology-packed bubble that spills its chemical contents like a broken piñata when encountering the virus. Such a detector could be positioned on a wall or ceiling, or in an air duct, where there's constant air [...]
