MIT bioengineer advances survival, promise of adult stem cells

...row from the hip, which is a much less painful and invasive process than removing bone, and transplant the stem cells from that marrow into the injury site. Although patients' own marrow has been used successfully in certain situations, Griffith and her clinical collaborators believe that the inflammatory...

How fish mend a broken heart

...f signals are known for their ability to encourage invasive cell behavior, Poss explained. Indeed, they found, heart muscle cells produce the growth factor, while epicardial cells harbor receptors that are triggered by the signal. When the researchers experimentally blocked the Fgf signal, heart regeneratio...

Invasive ants territorial when neighbors are not kin

...ity of California, San Diego biologists shows that invasive Argentine ants appear to use genetic differences to distinguish friend from foe, a finding that helps to explain why these ants form enormous colonies in California. In the December issue of the journal Molecular Ecology, the biologists provide th...

Math model predicts cancer behavior

Diabetes slows nerve recovery after heart transplant

...rvous system of the heart, said Bengel. "There are invasive methods that allow for the measurement of neurotransmitters released to the blood, offering indirect conclusions about the presence, storage and release of neurotransmitters from neurons. These methods require complicated and laborious sampling of bl...

Natural protein stops deadly human brain cancer in mice

...jected with cells that were not pretreated, large, invasive cancers grew. In the mice with BMP4-treated cells, no cancers grew at all. Three to four months after injection, all mice that got untreated cells died, and nearly all mice with BMP4-treated cells were alive. Next, the scientists delivered slow-re...

Newly identified biomarker detects and regulates spread of brain tumors

...as means that physicians will have a new minimally invasive method to track the success of treatments. These biomarkers, singly or in combination, will provide a fingerprint of the disease and be able in the future to better define the disease, predict what kind of treatment to use and allow doctors to monit...

Fast test for low blood flow in dogs detects early heart trouble

...hnique could also help eliminate many unnecessary, invasive catheterization procedures when there is no underlying blockage, or become a practical test to verify if treatments with drugs therapies, surgical bypass or stented arteries have worked to improve blood flow." Lardo, a biomedical engineer who speci...

Artificial cornea offers better results for infants, some blind patients

...revent infection. The current procedure is less invasive and cumbersome than some other efforts to implant artificial corneas. In the procedure carried out by Aquavella and other surgeons 30 years ago, physicians would remove a piece of leg bone from the patient and place the bone over the eye to help it h...

Stem cells found in adult hair follicles may provide alternative to embryonic stem cells

...s, they are readily accessible through a minimally invasive procedure and could lead to using a patient's own hair as a source for therapy without the controversy or medical issues of embryonic stem cells. "We see the potential for cell replacement therapy in which patients can be their own donors, which w...

Edge density key to controlling gypsy moth spread

...rstanding the underlying patterns in the spread of invasive species is important for successful management." The accidental release of the gypsy moth in 1869 in Massachusetts has led to an infestation covering more than 386,000 square miles of the U.S. Northeast. Native to Europe and Asia, gypsy moths are c...

New moth variety disarms plants guarded by selenium

How it worksUltimately, cells specific to the patient can be engineered to live on and function as part of the miniature electronic chip. The wireless biosensor is...

Three-dimensional, miniature endoscope opens new diagnostic possibilities

...ch may greatly expand the application of minimally invasive diagnostic and therapeutic procedures. In the October 19 issue of Nature, the team from the Wellman Center for Photomedicine at MGH describes their prototype device and a demonstration of its use in a mouse model. "This new ultraminiature endosco...

Elasticity imaging identifies cancers and reduces breast biopsies

Elasticity imaging is a modification of a routine ultrasound exam. It is like a manual self-exam but much more sensitive. The noninvasive technique works by g...

Ocean temperature predicts spread of marine species

...l component for managing commercially important or invasive species, O'Connor said. "For many animals, the larval phase is the only chance for babies to get away from parents. Dispersal prevents inbreeding; for some species, this is a time to move from breeding ground to habitat where they'll mature," she sai...
