Gene transfer using mutant form of good cholesterol cuts vascular plaque and inflammation

...pe apo A-I gene transfer led to about a 25 percent decrease in the amount of plaque buildup in the animals' aortas and other vessels. Apo A-I Milano gene transfer resulted in a 65 percent reduction. The amount of gene product (protein) produced by each gene was identical, measured in the blood and in the plaq...

Scientists use an 'ice lolly' to find polar bacteria in their own backyard

...ction" Said Professor Walker. These findings will decrease the costs involved in the further study of such bacteria and their properties, as scientists will no longer need expeditions to the poles in order to isolate the bugs; they can find them in their own backyards. ...

Robots manipulating animal behaviour

...g to a potential increase in competitiveness and a decrease in costs. "A robot interacting with animals, even if it is not mobile, could be used for numerous tasks, such as herding or milking. Our project demonstrates that the fields of biology and IT can work together more closely in future." Though the pro...

Cutting calories slightly can reduce aging damage

...cted diet, had the reverse outcome - they showed a decrease in these molecules in the liver. Leeuwenburgh said the study results support the theory that cell death and aging-related organ damage are caused by unstable molecules known as free radicals and by cellular oxidation and inflammation. "In a calorie...

Wasps queue for top job

...rectly benefit themselves, but they simultaneously decrease their own future survival and fecundity because helping is costly. It involves energy-expensive flight to forage for food, and leaving the nest is dangerous. We have found that the brighter the individual wasp's future, the less likely it is to take ...

...ach day--are what Sjogren speculated would cause a decrease in quality of the volunteers' lives. "The medications are tough to take," she said. On initial questionnaires, study volunteers reported that they were depressed; anxious about their health, families, and careers; and having trouble sleeping. Once t...

Meth promotes spread of virus in HIV-infected users

...or, we can develop ways to block that receptor and decrease the viral spread," said Nair. "We have to approach this disease from as many different perspectives as possible. "If we could prevent the upregulation of the meth-specific dopamine receptor by blocking it, we may be able to prevent the interacti...

Snakes' virtual glasses, leopard spots and all-optical transistors

...s the plasmons to interact in ways that enhance or decrease the transmission of the signal beam through the film. That is, the film acts as an all-optical transistor, with the potential to serve as a building block in optical circuits and optical versions of microelectronic devices. Multiple Choice Makes ...

UCSD researchers develop 'smart petri dish'

...ns "before traditional assays are able to detect a decrease in viability, demonstrating the potential of the technique as a complementary tool for cell viability studies." In addition, they add, their method "is noninvasive and can be performed in real time, representing a significant advantage compared to ot...

Global warming may have damaged coral reefs forever

...mplified as time goes on. Moreover, the observed decrease in herbivorous fish is a key concern as they control algal spread. Researchers speculate that the reefs' inability to reseed is down to their relative isolation. A lack of nearby reefs to provide larvae which could settle and grow into new coral s...

"For instance, drugs could be designed to decrease PI3K in cancer patients or those with proliferative diabetic retinopathy or macular degeneration, or designed to increased it in a damaged heart," he says. Next steps for the research team include identifying the signaling events by which PLCg inf...

Tiny airborne particles are a major cause of climate change

... aerosols ?those containing black carbon ?can also decrease cloud cover, ultimately leading to a warming effect. This occurs as black carbon absorbs part of the sun's radiation, warming the surrounding atmosphere and reducing the difference in temperature between the Earth's surface and the upper atmosphere. ...
