Scientists unveil nanoparticle for photoacoustic imaging

Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University of Washington is a first step toward making this possible.UW researchers have developed a multifunctional nanoparticle that eliminates the background noise, enabling a more precise form of medical imaging - essentially erasing the haystack, so the needle shines through. A successful demonstration with photoacoustic imaging was reported today (July 27) in the journal Nature Communications.

Scientists develop laser activated carbon nanoparticles for drug, gene delivery

Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers administered a small-molecule marker compound to 90 percent of targeted cells - while keeping more than 90 percent of the cells alive.

Scientists discover mechanism behind flushing reaction caused by nicotinic acid treatment

Cholesterol influences the health of our hearts and blood vessels. Conventional treatment attempts to reduce the level of "bad" cholesterol, LDL cholesterol, in the blood plasma. The opposite approach, which involves increasing the concentration of "good" HDL cholesterol using nicotinic acid, has proven unpopular among patients up to now. The reason for this is that treatment with nicotinic acid has an unpleasant but harmless side-effect: the drug makes patients turn quite red in the face. Scientists at the Max Planck Institute for Heart and Lung Research in Bad Nauheim have now discovered the mechanism behind this effect, which is known as flushing. This will enable the development of flush inhibitors and thereby the more effective prevention of cardiovascular diseases.

Scientists discover repair mechanism of photolyase in sun damaged DNA

Researchers have long known that humans lack a key enzyme one possessed by most of the animal kingdom and even plants that reverses severe sun damage.For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA.The discovery holds promise for future sunburn remedies and skin cancer prevention.

Researchers develop laser-induced thermal therapy to treat cancer

A group of researchers from Wake Forest University Baptist Medical Center is developing a way to treat cancer by using lasers to light up tiny nanoparticles and destroy tumors with the ensuing heat. Today at the 52nd Annual Meeting of the American Association of Physicists in Medicine in Philadelphia, they will describe the latest development for this technology: iron-containing Multi-Walled Carbon Nanotubes threads of hollow carbon that are 10 thousand times thinner than a human hair.

Researchers compare impact of heat waves on mortality in different European cities

Heat waves may cause increased mortality but, until now, there has been no single scientific definition for the occasional bursts of hot weather that can strike during the summer months. Researchers writing in BioMed Central's open access journal Environmental Health have created a definition that they use to document, for the first time, how heat wave mortality impact differs between European cities.
