Gene therapy via ultrasound could offer new therapeutic tool

Pictured is a fluorescently labeled endothelial cell monolayer, pseudocolorized in blue/green, and imaged using spectral confocal microscopy.  One cell has been selectively perforated via ultrasound-induced microbubble cavitation (simultaneously captured by ultrafast imaging, top panels), allowing the entrance of a model therapeutic (orange).  We investigated the biophysics of how rapid microbubble oscillation triggered by ultrasound waves can be used to enhance cellular uptake and increase vascular permeability.  This approach, referred to as sonoporation, has utility in selectively delivering large molecules, such as therapeutic nucleic acids for cancer and cardiovascular disease, directly into target cells.Combining ultrasound energy and microbubbles to poke holes in cells may prove to be a new tool in the fight against cardiovascular disease and cancer, according to researchers from the...

Cloth masks offer poor protection against air pollution

Richard Peltier, Kabindra Shakya and colleagues believe theirs is the first study to rigorously test disposable surgical masks and washable cloth masks, widely used in Asia and Southeast Asia for personal protection against airborne particulate matter. They found that cloth masks reduced exposure somewhat, but 'the most commonly used cloth mask products perform poorly when compared to alternative options available on the market.'Results of a new study by environmental health scientists at the University of Massachusetts Amherst suggest that inexpensive cloth masks worn by people who hope to reduce their exposure to...
