Laboratory-engineered liver tissue could be extremely useful, helping doctors to screen new drugs, and it could even one day be used for transplants. Unfortunately, it's also very difficult to replicate the organ's complex structure and functions outside of the human body. Now, researchers from China's Northwest A&F University have managed to construct artificial tissue that's proving effective at mimicking the real thing.
If you don't know what diathermy is, you're not the only one. It's actually been around since 1907, and involves using high-frequency electromagnetic currents to generate heat in body tissue, accelerating the healing of injuries in the process. While it's previously been limited to clinical settings, ReGear Life Sciences' wearable Vivy device is designed to let people deliver their own treatments, wherever they happen to be.
A new study by a team of scientists at the University of Maryland (UMD) indicates that a common chemical can reverse the symptoms of the premature-aging disease progeria and perhaps even those of normal aging. According to the study, small doses of methylene blue can undo the damage done to cells by the genetic defect that causes progeria with a speed and reliability that the scientists claim is "like magic."
A fast-acting medical device developed for emergency treatment of a gunshot or other penetrating wound on the battlefield has been cleared for civilian use by the US Food and Drug Administration (FDA). The XStat 30 is a plastic syringe that can stop severe bleeding within around 20 seconds through the injection of small sponges into a wound, and will now be available for use by the general population.
Scientists from Oregon State University have developed a new delivery system for cancer treatment that attacks the condition simultaneously with three different drugs. According to the team, it's likely to prove particularly effective against cancers that spread through the lymphatic system, such as metastatic melanoma.
A new system for growing heart tissue in the lab may make future heart, liver, and lung repair much easier. University of Toronto scientists have developed asymmetrical honeycomb-shaped 2D meshes of protein scaffolding that stick together like Velcro and imitate the environments in which tissue and muscle cells grow in the body.
In order to treat injured joints, patients are often advised to apply
heat. This typically takes the form of a hot water bottle or
microwavable hot pack (which are cumbersome and cool off) or a heating
pad (which needs to be plugged in). Now, however, scientists from Korea
and the US have created a battery-powered thin mesh that applies heat
and stays put.
Future cancer treatments may target your genes rather than the cancerous cells themselves. A new study found that reactivating a single gene was enough to stop and reverse colorectal cancer (that's cancer of the colon, or bowels) in mice, with a return to normal intestinal functions within just four days and tumors gone within two weeks. The concept, though not the specific method, could lead to new treatments of a variety of cancers.
A team of graduate students at Johns Hopkins University has created a prototype device that delivers non-invasive brain stimulation to sufferers of Parkinson's disease. The brain-zapping headwear, dubbed STIMband, helps to reduce the severity of symptoms without requiring a visit to a hospital or doctor's office.
A team of MIT researchers has discovered a new target for drug treatments for prevalent diseases such as malaria. The findings focus on a membrane between the parasite and its host cell, with scientists successfully identifying a family of proteins that, when targeted, could cut off nutrients to the parasite.
