OHSU study says stem cell 'fusion' occurs in tumors

...of intestinal cancer. The donor-derived cells were readily detected in the intestinal tumors of the male mice. To show that the transplanted donor cells fused with the tumor cells, the scientists detected proteins or markers from both the female donor and male recipient cells in tumors. The only way both do...

St. Jude test of bird flu vaccine proves successful

...s that mutates so that it adapts to humans and can readily spread from person to person, Webby said. Flu experts and public health officials fear that such an H5N1 variant would trigger a human pandemic (worldwide epidemic). Webby is scheduled to present the findings of this study at the U.S. Public Health ...

Tests for 'face-blindness' reveal disorder may not be so rare

...tition among the faces in the series, even as they readily identify repeated pictures of other objects. Reports of prosopagnosia date back to antiquity, although it wasn't until 1947 that researchers made the first modern, extensive description of symptoms. The neurological basis of the disorder remains poo...

MIT creates 3-D scaffold for growing stem cells

...ously thought." The active motif method could be readily adapted to studying cell-to-cell interaction, cell migrations, tumor and cancer cell interaction with normal cells, cell-based drug testing and other diverse applications. "I believe that in the next 20 years all cell cultures will be in 3D with th...

New biochip helps study living cells, may speed drug development

...d and could be mass-produced in the future. Such a readily available chip could record reams more data than patch-clamping, he said. Ion channels and pumps establish a difference in electrical potential across a cell's membrane, which cells use to create energy and transfer electrical signals. By quickly ...

A natural chemical found in strawberries boosts memory in healthy mice

...mory in vivo." "The good news is that fisetin is readily available in strawberries but the bad news is that because of its natural product status there may be little financial interest in getting it into human clinical trials for diseases associated with memory loss such as Alzheimer's, where the treatment...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

... values. With that information, a technician could readily reference a Raman shift for a particular virus to identify an unknown virus. To make their finding commercially viable, they're developing a business model, seeking venture capital and exploring ways to mass produce the silver nanorods. Next year,...

Scientists find mutations that let bird flu adapt to humans

...vian flu virus. Most viruses, including influenza, readily swap genes with one another. In the new study, conducted by an international team of researchers, the viruses isolated from human patients in Vietnam and Thailand could recognize both human and avian cell receptors. By contrast, the viruses found ...

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

...milar to other types of adult stem cells, 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 p...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

... the ammonia into nitrites and nitrates, which are readily absorbed by plants or removed by other microbes. Animals and people, in turn, obtain nitrogen by eating plants and other herbivorous animals. That was the dogma taught for decades in biology classes-until September 2005, when David Stahl of the Un...

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

... to Lardo, blood flow in these tiny vessels can be readily detected by high-resolution equipment like 64-CT scanners. The device produces precise, 3-D, diagnostic pictures within five to 10 seconds by quickly passing X-rays through the body. The resulting digitized signals, called "slices" - and there a...

Study shows antibiotic-resistant bacteria responsible for increase in muscle infections

...res. These community-acquired strains appear to be readily transmitted from person to person and can cause serious skin and soft tissue infections as well as invasive infections such as bone or joint infections or pneumonia. Failure by physicians to suspect this kind of drug-resistant staph can lead to treat...

Selecting life: Scientists find new way to search for origin of life

...rdial soup could be concentrated and selected on a readily available mineral surface. The challenge since has been to determine which of the countless biomolecules/surface interactions are the most likely candidates to the first steps to life. "Crystal surfaces are complicated," Hazen continued. "They ha...

Rearing an army to save wheat

... help us have the ability to have parasitoids more readily available for future efforts," Weaver said. "Right now, we have to locate a large population of these beneficial insects before we can redistribute them. If we can reliably have them available at a known location, we could do our job much more effici...

Designer babies - what would you do for a 'healthy' baby?

...terventions in child rearing as "design acts" more readily than men. People over 50 interpret certain interventions as "design acts" more readily than people under 25. Because of "parental uncertainty" - the idea than women know for certain if a ...

Cells selectively absorb short nanotubes

...notubes (SWCNTs) shorter than about 200 nanometers readily enter into human lung cells and so may pose an increased risk to health, according to scientists at the National Institute of Standards and Technology (NIST). The results of their laboratory studies appear in an upcoming issue of Advanced Materials.*...

Tissue engineering for craniofacial reconstruction

...ndous control of scaffold morphology. HIPEs can be readily molded into the irregular shapes often required in craniofacial reconstruction and cured in situ to a rigid foam. They have demonstrated that emulsion templating can be used to generate rigid, biodegradable scaffolds with interconnected pores. These ...

Scripps Research study reveals new activation mechanism for pain sensing channel

... channels bind in a lock-and-key mechanism that is readily reversible," said Lindsey Macpherson, another author of the study and a Ph.D. candidate in the Scripps Research Kellogg School of Science and Technology. "The mechanism by which noxious compounds activate TRPA1 is unique. For example, compounds that ...
