Multi-tasking nanoparticle both seeks and destroys cancerous cells

Nanoparticles hold great potential as a way of both detecting cancer cells and delivering the drugs to treat them. One hurdle that has proven difficult to overcome is incorporating these properties into one multi-purpose device, as nanoparticles are generally engineered with either goal in mind. In what appears a promising development, researchers at the University of California Davis (UC Davis) Cancer Center have created a multi-tasking nanoparticle shown to be effective both in the diagnosis of a tumor and attacking its cells – a flexibility that could lead to new treatment options for cancer patients.Read More

Students developing an injectable foam to treat battlefield wounds

When a soldier is wounded on an extremity such as an arm or leg, applying a bandage and/or tourniquet to stop the bleeding is typically a fairly straight-ahead process. However, in cases where an injury is received right at the junction between an extremity and the torso – places such as the neck, shoulder or groin – things get a lot trickier. Gauze pads treated with clotting agents are often packed into the wound, although they're not always sufficient for staunching the flow. A group of students from Johns Hopkins University are working on a better alternative, in the form of a hardening foam that's injected into the wound. Read More

Researchers engineer red blood cells to deliver therapeutic payloads

Although several studies are currently exploring the use of man-made nanoparticles for delivering medication to targeted areas of the body, care must be taken to ensure that those particles don't cause adverse reactions when introduced to the bloodstream. Scientists at the MIT-affiliated Whitehead Institute, however, are taking a different approach to the same basic concept. They've developed a method of attaching chemical payloads to red blood cells.

Human stem cell treatment gets mice with MS-like condition walking again

When scientists at the University of Utah injected human stem cells into mice disabled by a condition similar to multiple sclerosis, they expected the cells to be rejected by the animals' bodies. It turned out that the cells were indeed rejected, but not before they got the mice walking again. The unexpected finding could have major implications for human MS sufferers. Read More

"Heart disease-on-a-chip" could usher in an age of personalized medicine

When we've previously heard about "organs on a chip," they've been miniature recreations of healthy organs. If they're being used for research into the treatment of health problems, however, then it only makes sense that those "organs" should have something wrong with them. With that in mind, a group of Harvard scientists have created the world's first lab-grown sample of functioning human heart tissue that has a cardiovascular disease. Read More

Researchers turn to GPUs to improve cancer therapy

Medical physicists at the University of Texas Southwestern Medical Center are latching on to advances in the computational speed of graphics processing units (GPUs) to drastically reduce the time required to calculate radiation therapy plans. The approach also increases the accuracy of calculations, allowing for faster, more precise, and more adaptable treatment of cancer patients.Read More

Vibrating capsule treats constipation by buzzing the intestine

According to Dr. Yishai Ron, a researcher at Tel-Aviv Sourasky Medical Center, nearly half of the people who take medication for chronic constipation are unsatisfied with the results. That dissatisfaction can stem from unwanted side effects, concerns over the long-term safety of the medication, or "the fact that it simply doesn’t work." That's why he and his colleagues have created an oral capsule that relieves constipation by vibrating its way along the intestinal tract. Read More
