Unique tomatoes tops in disease-fighting antioxidants

...carotenoids, and scientists are working on ways to enhance the fruit's antioxidant content and composition," Schwartz continued. The findings appear in a recent issue of the Journal of Agricultural and Food Chemistry. Lycopene is a carotenoid that contains a variety of related compounds called isomers...

Temple University Hospital investigates treatment for cervical dysplasia

...iladelphia. "This product candidate is designed to enhance the body's immune response to cervical dysplasia, and is being developed to offer patients with cervical dysplasia and healthcare providers an option to surgical intervention," explained Hernandez. "Qualified participants must be 25 or younger, with ...

Genetically engineered blood protein can be used to split water into oxygen and hydrogen

...le itself being modified by genetic engineering to enhance the efficiency of the process. The resulting molecular complex was proven to be sensitive to light, and can capture light energy in a way that allows water molecules to be split into molecules of hydrogen and oxygen. Dr Stephen Curry, a structural ...

Protein structure initiative launches new resources for the scientific community

...mmunity, but the new resources should dramatically enhance accessibility." PSI-Materials Repository The Harvard Institute of Proteomics ( www.hip.harvard.edu ), part of the Harvard Medical School in Boston, Mass., will operate the PSI-Materials Repository (PSI-MR). With $5.4 million in funding over ...

NHGRI aims to make DNA sequencing faster, more cost effective

...emistry, chemistry and physics with engineering to enhance the whole effort to develop the next generation of DNA sequencing and analysis technologies. Since 2004, NHGRI has awarded $83 million to investigators to develop both "near term" and revolutionary sequencing technologies. "It is very important that...

Anticipation plays a powerful role in human memory, brain study finds

... "Just the expectation of seeing something bad can enhance the memory of it after it happens." A teacher who struggles with stage fright, for example, might feel anxious before every class she has to teach. The UW-Madison work suggests that the longer she spends dreading her next lecture, the stronger her ...

Sequencing of the oyster mushroom genome

... might understand its biology and reproduction and enhance its utilization. Moreover, an understanding of the evolutionary history registered in the genome of the oyster mushroom and its comparison with other histories registered in other genomes that have been ?or are currently being ?sequenced (human, a...

Researchers link ocean organisms with increased cloud cover and potential climate change

... form cloud droplets. When oxidized, isoprene may enhance the effect of DMS by increasing the number and size of the particles while helping them to chemically attract more moisture. The impact of isoprene on atmospheric particulate matter was previously thought to be important only for terrestrial plants,...

Vaccination with embryonic stem cells prevents lung cancer in mice

... "supercharges" the immune response and appears to enhance the vaccine-induced immunity to cancer. Prof Eaton explained: "We needed a delivery vehicle for GM-CSF and chose STO fibroblasts because they are often used as a 'feeder layer' to maintain these particular mouse embryonic stem cells in their embry...

Cocaine high caused by interference in neuronal receiving stations

... subunit or inactivated the NR2B subunit tended to enhance such behavioral responses to cocaine. "These results provide strong evidence supporting a critical role of the D2R-NR2B interaction in mediating cocaine's effect on [kinase binding and phosphorylation] and in constructing a full-scale motor respons...

Scientists win grants to develop $1,000 genome sequencing technology

.... His expertise will be utilized to accelerate and enhance the sequencing process. The UCSD team will use an experimental method for DNA sequencing aimed at developing a method for fabricating high-density arrays of nanoparticles, with one fragment of DNA attached to individual nanoparticles in the arrays...

Drug can quickly mobilize an army of cells to repair injury

...ack or stroke. The ability of angiogenic cells to enhance recovery from heart attack has become a hot resear...e of injury or low oxygen," he says. "That way you enhance a normal repair mechanism instead of using the brute force of injecting a mixture of many cell types...

Regulating the nuclear architecture of the cell

...e difficult. Other genes called E(var)s act to enhance variegation in Drosophila. One way they do this is by acetylation of the H3 histone's fourth amino acid, also a lysine. The effect is to open the chromatin at that site, making the DNA accessible. "Acetylating H3K4 and demethylating H3K9 can acti...

Unraveling where chimp and human brains diverge

... at different speeds, metabolize energy faster and enhance connections between brain cells across different brain regions." Future UCLA studies will focus on linking the expression of evolutionary genes to specific regions of the brain, such as those that regulate language, speech and other uniquely huma...

Some butterflies travel farther, reproduce faster

...' evolution. "We may be selecting for genes that enhance the dispersal or migratory capability of animals when we fragment the landscape," Fescemyer said. The animals best able to migrate are more likely to survive and reproduce. "What we learn could apply to any organism that has to move to find food," he...

Funding to tackle hospital superbugs

...mon Jones has already identified new pathways that enhance the bodies natural defence mechanisms to promote the clearance of infection. The new approach has been named "Resolution Therapeutics" by the Cardiff researchers. It is hoped that research in the School of Medicine will lead to the development of...

U-M researchers use nanoparticles to target brain cancer

... the tumor. Iron oxide is a contrast agent used to enhance magnetic resonance imaging, or MRI. "Photofrin goes into tumor blood vessels and collapses the vasculature, which then starves the tumor of the blood flow needed to survive. The problem with free photofrin therapy is that it can cause damage to he...

New tool helps blood specialists improve patient care
