gizmag- Healing Nanoparticles

The relative sizes of a standard pacemaker and the new fetus-sized model (Image: CHLA)
In the near future, it's entirely possible that babies with heart defects will be born with complete pacemakers already installed. That's because scientists at Children's Hospital Los Angeles (CHLA) and the University of Southern California have developed the world's first fully-implantable pacemaker for fetuses.  Read More
LabDisk is a device for detecting multiple diseases quickly and non-invasively
Typically, tests for diseases must be done one disease at a time, and can take days to be processed through a lab. A new device developed in an EU project, however, can test for several diseases at the same time and provide results within an hour. The LabDisk is designed for use in Africa.  Read More
Burns healed in half the time in mice treated with the nanoparticles compared to those lef...
An experimental nanoparticle therapy cuts in half the time wounds take to heal compared to natural healing. The therapy has already been tested successfully in mice and will soon be tried on pigs, whose skin is similar to that of humans. If it reaches clinical use in humans, this sort of nanoparticle therapy could be used to speed healing of surgical incisions, chronic skin ulcers, and everyday cuts and burns and other wounds.  Read More
Endothelial cells grown from stem cells in the blood, stained with fluorescent markers (Ph...
Scientists have developed a blood test using human stem cells that predicts whether new drugs will cause severe side effects. The test, which only requires blood from a single donor, could help prevent catastrophic inflammatory reactions known as a cytokine storm in people participating in drug trials.  Read More
A new technique involving magnetic nanoparticles allows therapeutic molecules to cross the...
The blood-brain barrier is a highly selective semipermeable barrier running inside almost all vessels in the brain that lets through water, some gases and a few other select molecules, while preventing potentially toxic elements in the blood from entering the brain. Researchers from the University of Montreal, Polytechnique MontrĂ©al, and CHU Sainte-Justine say that currently 98 percent of therapeutic molecules are also blocked by the barrier, but they have developed a technique using magnetic nanoparticles that opens the door for such molecules, thereby also opening the door to new treatments for brain diseases.  Read More
The mini-lungs could be used to test the  effectiveness of potential new drugs (Photo: Nic...
Researchers at the University of Cambridge have grown functional "mini-lungs" using stems cells derived from the skin cells of patients with a debilitating lung disease. Not only can the development help them in coming up with effective treatments for specific lung diseases like cystic fibrosis, but the process has the potential to be scaled up to screen thousands of new compounds to identify potential new drugs.  Read More
A form of saccharin, an artificial sweetener, could lead to the development of drugs to ba...
Whether it be advice from a dentist or preparing their body for beach season, there's a host of reasons people might reach for an artificial sweetener rather than sugar – though its cancer-fighting properties are unlikely to be one of them. But new research shows that the common sugar substitute known as saccharin could hamper the growth of particular cancers, with scientists claiming it could form the basis for new kinds of drug treatments.  Read More
An algorithm developed by University of Warwick researchers can detect and differentiate b...
While blood tests are used to rule out other forms of arthritis, the diagnosis of osteoarthritis (OA) generally relies on physical symptoms, with X-rays or MRI scans used for conformation if required. But researchers at the University of Warwick in the UK have identified a biomarker for OA that could lead to a blood test that could diagnose it, and rheumatoid arthritis (RA), years before physical symptoms present themselves.  Read More
A new drug-like molecule developed at the Walter and Eliza Hall Institute shows promise in...
Scientists at the Walter and Eliza Hall Institute of Medical Research in Australia have developed a new drug-like molecule with the ability to inhibit a key signal that triggers inflammation in the body. The scientists say the molecule has already shown promise for putting the brakes on the progression of multiple sclerosis (MS).  Read More
The UC Berkeley researchers are hopeful that the smart bandage will do more than prevent n...
Bedsores are more than a pain in the backside for bedridden folk, they can develop into dangerous infections and heighten the chances of a patient dying. While swollen ulcers on the skin are a pretty sure sign of their presence, by this point it is often too late for some of their effects to be reversed. But a team of researchers have developed what could function as an early warning system, a smart bandage containing flexible electronics that detects tissue damage before it becomes visible on the surface of the skin.  Read More
