For the past several months, Omicron subvariants BA.4 and BA.5 have dominated COVID-19 cases in the U.S. But now, there’s a class of new COVID subvariants on the rise and one in particular is getting plenty of attention. It’s called XBB—or Gryphon—and there’s a chance it could overtake everything else out there. XBB is getting a lot [...]
Nucleic acid therapies involving DNA or RNA have significant potential to treat genetic disorders, infectious diseases, and cancer; however, research suggests that less than 1% of injected nucleic acid doses reach target cells in an active form. An article in WIREs Nanomedicine and Nanobiotechnology highlights two of the major barriers to this therapeutic strategy, [...]
The US Food and Drug Administration on Tuesday approved Hemgenix, a new drug to treat hemophilia. Manufacturer CSL Behring set the price at $3.5 million per treatment, making it the most expensive drug in the world. Hemgenix is a gene therapy to treat adults with hemophilia B, a genetic bleeding disorder in which [...]
Some wounds just won’t heal. Infections, diseases like diabetes, and suppressed immune systems often stack up to slow healing. Chronic wounds can last months and lead to anxiety and depression. In the worst cases, they are life threatening. Cost of treatment has soared to $25 billion each year. So far, however, solutions for treating [...]
Over the years, researchers have tried hard to comprehend topographic signals that promote cell mechanical sensitive responses. The extracellular matrix (ECM) provides a complex cellular microenvironment that controls cellular behavior. Nevertheless, only a few functions of these factors are understood, and most remain obscure. An article published in Advanced Sciences presented a convenient method to demonstrate [...]
There is now an imminent threat of measles spreading in various regions globally, as COVID-19 led to a steady decline in vaccination coverage and weakened surveillance of the disease, the World Health Organization (WHO) and the U.S. public health agency said on Wednesday. Measles is one of the most contagious human viruses and is [...]
In a recent study, it was shown that people with long Covid have had physical changes to their brains several months after experiencing the initial infection. The study included MRIs of patients who continued to suffer from symptoms six months later, which showed clusters of mineral deposits in the brain linked to fatigue and [...]
Western University in London, Ont., is building a unique research lab to study humanity's greatest viral threats — a secret weapon, if you will, one that it's expected would put Canada and the world in a better position if and when the next pandemic happens. "[This is] the next level, in terms of having a facility that really can [...]
Cancer patients are testing a medicine made of antibodies that were designed from scratch on a computer in Israel and whose inventor has “programmed” them to “decide” whether cells surrounding tumors are bad or good. If the trial, which is underway in Australia, goes according to plan, these antibodies will fight cells that help the [...]
In an article published in the journal Scientific Reports, researchers presented the potentiostatic deposition used to electrodeposit nickel (Ni) and nickel-graphene (Ni-G) films on copper substrates. Myristic acid (MA) was employed to alter the plane of the electrodeposited coatings to create superhydrophobicity (SHP). With water contact angles of 159° and 162°, respectively, the Ni-G films altered with MA (Ni-G-MA) [...]
