A drug long-used to counter the negative effects of chemotherapy has won US Food and Drug Administration (FDA) approval for use in treating the nasty effects of exposure to radiation following a nuclear disaster. Known commercially as Neupogen, the drug has been shown to work by shielding the body's white blood cells to heighten a patient's chances of survival.
A team of researchers from MIT has discovered that creating body implants at a certain size maximizes the amount of time they can spend operational in the body before being neutralized by the immune system. In the future, the research could lead to longer term treatment avenues for diseases that could do away with the need for painful and repeated injections.
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.
A study of skin wound healing in 40 (human) volunteers has found that electrical stimulation significantly speeds up the healing process. The researchers hope to now develop and test dressings and devices that could be used in treatment of human or veterinary surgical wounds, sports injuries, and other serious skin trauma.
Researchers at the Universidad Carlos III de Madrid (UC3M) and the
Institute Ramón y Cajal for Health Research (IRYCIS) have created a new
device that significantly cuts down the time required to perform a skin
biopsy. It doesn't require any specialized skills to use, and could open
the door to faster skin cancer diagnoses.
A new type of medical device could one day put the minds of chronic pain sufferers at ease by distributing the body's own natural pain relief signals at just the right time. Developed at Linköping University in Sweden, the tiny "ion pump" is made from organic electronics and could be implanted in patients, serving to cut off pain signals in the spinal chord before they make their way to the brain.
In order to confirm that a patient presenting with a heart attack has in
fact had one, doctors typically use bulky, expensive lab equipment ...
which isn't always available to clinicians in developing nations or
rural locations. That's why scientists from Korea's Pohang University of
Science and Technology have created a simple thermometer-like device
that reportedly does the job.
In Africa, the spread of parasitic worms known as Loa loa is seriously hindering the efforts of health care workers to cure particular rampant diseases. Though there are drugs available to treat both river blindness and lymphatic filariasis, if they are administered to a patient who also happens to also be infected with Loa loa the consequences can be lethal. This is complicated further by the inherent difficulties in screening for the worms, but a newly developed mobile phone microscope needing only a drop of blood to automatically detect the parasite promises to make things a whole lot simpler.
A key battleground in the fight against cancer has been the development of vaccines to stop tumors taking hold. These are intended to kick the body's own immune system into action to fend off the cancerous cells, with immunotherapy drugs for melanomas, prostate and lung cancer all emerging in recent years. But one hurdle oncologists are yet to tackle with any great success is a vaccine for breast cancer. New research now suggests this mightn't be all that far away, with the discovery that loading cancer antigens into silicon microparticles serves to greatly boost the immune response.
