Novel Enzyme Shows Potential As An Anti-HIV Target

...y of all seven SIRT proteins to deacetylate Tat by placing them in a test tube with Tat proteins. Though three SIRT enzymes caused Tat acetylation, only one, SIRT1, is a nuclear enzyme, like Tat, suggesting that SIRT1 might work similarly in living cells. Ott and colleagues went on to show that transcriptio...

Poplar trees redirect resources in response to simulated attack

...g their nutrients away from the site of attack and placing them into storage for later regrowth," Ferrieri said. Supporting evidence comes from the amount of carbon-11 the scientists detected in isoprene, a hydrocarbon gas that is a byproduct of sugar synthesis in the leaves. That research, reported in Plan...

Gene Therapy Cures Inherited Liver Disease In Rats

.... Crigler-Najjar syndrome is currently treated by placing the person under special UV lights. It is an unwieldy and time-consuming treatment. While Lee does not think that cure would be possible in all adults with this technique, he does think it poses a real promise for long-term alleviations of the toxic...

They achieved this by placing the mice in a chamber filled with normal room air laced with 80 parts per million of hydrogen sulfide, a chemical normally produced in humans and animals that is believed to help regulate body temperature and metabolic activity. Within minutes of br...

The three countries with the highest prevalence of obesity were Malta (7.9 per cent), the United States (6.8 per cent), and England (5.1 per c...

Study: 'homemade' gene expression technology unreliable

...ession of individual genes is turned up or down by placing copies of DNA or RNA molecules labeled with fluorescent dyes on the slide, and examining whether the molecules that bind to a particular gene light up when viewed with a special scanner. By interrogating thousands of genes at once, scientists can qu...

Purdue researchers use enzyme to clip 'DNA wires'

...had previously developed a technique for precisely placing strands of DNA on a silicon chip and then stretching out the strands so that their encoded information might be read more clearly. The current work by Ivanisevic's team builds on that previous research. Kinsella created the magnetic particles, which...

Experiment station researchers to explore genome of disease-fighting fungus

...t would be cost-effective for many producers. "By placing the disease-fighting fungus directly onto the seed, it would continue to protect the plant throughout the growing season and spread throughout the root system." Finding unique genes involved in inducing plant resistance could also aid the greenhouse...

DNA constraints control structure of attached macromolecules

...nts is their programmability," Silverman said. "By placing two or more constraints on one molecule, we could generate multiple molecular states that would be programmable by DNA sequence. In other efforts, we would like to control macroscopic assembly processes by influencing the shapes of self-assembling mo...

Achilles heel of the herpes virus possibly found

...an cell. The researchers were able to show that by placing only the DNA sequence that encodes B5 into HSV-resistant pig cells, they could make the pig cells susceptible to HSV. They were also able to block viral infection of both human cells and susceptible pig cells by adding to cell cultures a synthetic pe...

Blink, and the brain misses it

...less of blinking. The researchers achieved this by placing a light-emitting optical fibre in the mouth of volunteers wearing light-proof goggles. Because the light was bright enough to pass through tissues of the face, the fibre could be used to illuminate the retina through the roof of the mouth. Therefore,...

Scalpel-free surgery could reduce risk of HIV and hepatitis exposure for health care workers

...ed to the most inexperienced surgeons-in-training, placing them at greatest risk. "Sharpless surgical techniques combined with traditional precautions and early education for surgery trainees are the most practical ways to reduce the risk of infection to health care workers," said Makary. The researchers s...

Nicotine triggers the same brain reward circuitry as opiates

...en given a choice. The researchers found that just placing the conditioned mice in the chamber activated CREB. They also found that naloxone blocked this conditioned increase in CREB, and that mutant mice lacking CREB or pretreated with naloxone did not show any reward response to nicotine. However, naloxon...
