Researchers report technique for freezing and preserving genetically enhanced pig embryos

...iotechnology have reported success in freezing and preserving swine embryos that were created by in vitro techni... Dr. Prather and his team expect that freezing and preserving swine embryos will enable wide dissemination of swine with genetic traits that are commercially valu...

Recycled paper and compost could both be key tools to control plant disease

...o be applied to plants, less peat is required thus preserving peat bogs, and green waste and paper waste that would otherwise be land-filled is recycled. Professor Ralph Noble says: "This research shows that the use of such compost could provide clear commercial benefits to growers and ecological benefits fo...

Cell wall of pneumonia bacteria can cause brain and heart damage

...oculation of cell wall did not. "Our success in preserving cardiomyocyte function even in the presence of cell wall suggests that it might be possible to safely pre-treat people infected with S. pneumoniae with a drug that blocks PAF before we administer antibiotics," Tuomanen said. "This might protect the h...

Insulin receptor stops progression of Alzheimer's disease

...h PPAR delta producing the most striking effect in preserving the hypothalamus and temporal lobes, areas of the brain responsible for memory, learning, and behavior. In these brain regions, PPAR alpha and PPAR gamma were effective in reducing amyloid gene expression. PPAR delta had the most benefit for reducing...

Climate experts search for answers in the oceans

...ing these data sets to encourage data exchange and preserving them for long-term use. "People will be using these data 20, 50, and 100 years from now in ways that we can’t even imagine, so we need to do a lot of things today to ensure this irreplaceable information remains useful and understandable for deca...

St. Jude announces breakthrough in eye cancer treatment

...astoma. This would mean saving many more lives and preserving more vision." Rodriguez-Galindo is a co-author of the paper. Retinoblastoma can occur as a unilateral (one eye) or bilateral (both eyes) disease. In the case of unilateral disease, surgeons generally remove the eye that has the cancer in order to p...

New fMRI technology making brain tumor surgery safer

...ard in their quest to treat difficult tumors while preserving areas of the brain that are responsible for speech and movement. The Cincinnati specialists are among the first in the country to use new technology that integrates functional MRI (fMRI) data into high-tech surgical navigation systems. The fMRI dat...

Stem cell therapy shows promise for rescuing deteriorating vision

...xperimented with other cell types as therapies for preserving vision. The neural progenitor cells, a cell model developed by Wisconsin stem cell researcher Clive Svendsen, have been used experimentally to deliver the same growth factor in models of Parkinson's disease and Lou Gehrig's disease. Svendsen is also ...

UCLA/Toronto researchers unlock key to memory storage in brain

...rts the findings, which suggest a new approach for preserving memory in people suffering from Alzheimer's or other brain injury. "Making a memory is not a conscious act," explained Alcino Silva, principal investigator and a professor of neurobiology and psychiatry at the David Geffen School of Medicine at U...

Stem cells act through multiple mechanisms to benefit mice with neurodegenerative disease

... in treating a degenerative disease, significantly preserving function and extending life. The mouse model chosen falls in a class of genetic diseases that afflicts 1 in 5000 patients, typically children (called lysosomal storage diseases, described in more detail below), but which is often us...

Uniform language for describing genes of pathogenic and beneficial microbes

...nting infections by disease-causing microbes while preserving or encouraging the presence of beneficial microbes. The unified language under development in this effort is called The Gene Ontology (GO). The new terms added to the GO will significantly bolster what is already a powerful tool for scientists to c...

The quest for an effective HIV vaccine presents new possibilities, challenges

...e a beneficial effect by reducing viral levels and preserving critical cells needed to control infection. There will be a tremendous public health challenge as well, in an HIV vaccine that does not completely prevent the virus from establishing itself in the body." Once HIV enters the body, it infects crucia...

Confirmed -- deforestation plays critical climate change role

...ew body of information shows considerable value in preserving tropical forests such as those in the Amazon and Indonesia as carbon sinks, that they do not release the carbon back into the atmosphere as has been suggested," Dr Canadell says. "However, it also demonstrates the need to avoid higher levels of globa...

Machine preservation may promote more organ sharing

... more sharing of organs; it is a superior means of preserving organs out of body and provides a way to assess the viability of the organ." Stratta said machine preservation has played an important role in the Medical Center’s success transplanting kidneys at the outer limits of the ECD acceptance criteria, s...
