Invasion of the brain tumors

...drils that extend far from the primary tumor site, rendering conventional therapies ineffective and leading to an invariably poor prognosis. In a new study published online this week in the open-access journal PLoS Biology, Angela Johnston, Donna Senger, and colleagues at the University of Calgary injected imm...

Green tea boosts production of detox enzymes, rendering cancerous chemicals harmless

...les that would otherwise damage cellular DNA, thus rendering them inert. They actually convert known carcinogens to non-toxic chemicals, and studies have shown a correlation between deficient expression of these enzymes and increased risk of developing some cancers, Chow said. Expression of this enzyme ...

Computer graphics spills from milk to medicine

...al properties of participating media necessary for rendering realistic images has required extensive measurements and/or trial-and-error manual adjustments. The new model eliminates the restrictions of the Lorenz-Mie theory for participating media such as milk, in which the embedded particles (primarily pro...

Boston Univeristy bioengineers devise 'dimmer swith' to regulate gene expression in mammal cells

...fering RNA (RNAi) attaches to the functional mRNA, rendering it useless. The cell cannot turn it into protein. I was delighted to see that when the two systems are coupled, it is possible to completely turn a genes function off, said Deans. This switch is also reversible and tunable. By adding a chemical...

...wly formed vessels with stabilizing pericytes, and rendering new vessels more resistant to anti-angiogenic therapies. In a surprising study appearing online on July 19 in advance of publication in the August print issue of the Journal of Clinical Investigation, a team led by Lee Ellis from The University of Te...

Expert to provide update after 'worst tomato virus' hits California

... flowers of the tomato plants to die and fall off, rendering the plant unable to produce fruit. The good news is that the whitefly that carries the virus does not do well in colder areas, such as in Northern California, the state's primary tomato growing area. "This gives us hope that we have this under con...

With the research project that has been selected to receive the award, the VIB research group will seek to identify which mechanisms are involved in the purging of this coagulation factor and how they might develop strategi...

Also insects and nematode worms rely on the secretion of hormones to transmit information, but the compounds they use are often very different from the vertebrate coun...

Nanoparticles hitchhike on red blood cells: a potential new method for drug delivery

...ckly removed from the blood, sometimes in minutes, rendering them ineffective in delivering drugs. The research team, led by Samir Mitragotri, a professor of chemical engineering, and Elizabeth Chambers, a recent doctoral graduate, found that nanoparticles can be forced to remain in the circulation when attac...

Potato wart eyed as risk to potato production

...white, and then turn brown or black as they decay, rendering the potato tuber unrecognizable and inedible. There is a zero tolerance for the fungus that causes potato wart. As a result, this disease has been placed on the USDAs "Select Agent List" of plant pathogens deemed to pose a severe threat to plant h...

...ity rates of piglets due to diarrhea and anemia by rendering them more resistant to common infectious agents, the report states. Transgenic animals expressing the LF protein in the mammary gland and secreting high levels of LF in the milk may be generated to produce a whole new herd of diarrhea- and anemia-re...

New technique will produce a better chromosome map

...ise applies up to two tons of force to each slide, rendering the preparations very thin and high in contrast. This allows the production of much clearer, information-packed images. The technique has other advantages: Because it relies on light microscopy, it is faster and more economical than electron micros...

No pain, DOE Joint Genome Institute gains coveted ergonomics prize with 'Shake 'N Plate'

"We are first and foremost concerned with the health and safety of our employees, which was the original motivation for the formation of the DOE JGI Ergonomics Working Group," said Susan Lucas, hea...

Protein overexpression at heart of heart failure

...creased the activity of single ventricular L-VDCC, rendering these channels phenotypically identical to human and mouse heart failure. The authors conclude that electrical remodeling of the L-VDCC, based on gene expression changes, is an early step in a cascade ultimately induced in heart failure. This provi...

Scientists find potential 'off-switch' for HIV virus

... of pulling the chemical tail off the Tat protein, rendering it silent. The interplay between p300 and SirT1 comprises the resistor and can effectively keep the virus in its dormant phase. "SirT1 reduces the strength of the signal to replicate," Weinberger said. "It may prove to be the key part of the resis...

Erotic images prove useful in coaxing out unconscious brain activity

The subjects were then tested to see if their visual attention had shifted toward or away from the part of the visual field where the intact erotic image had appeared. The strongest shift in attention toward the a...
