LIAI scientists make major finding on potential smallpox treatment

...ion, similar to how an antibiotic treats and for a short time protects against a bacterial infection. "This makes Dr. Crotty's research even more interesting because his findings appear to offer a way to successfully treat the virus," Kronenberg said. "This could be very important should people become in...

Optimizing cell therapy against tumors is a balancing ACT

... is to keep the in vitro T cell expansion phase as short as possible to keep them naïve. These findings are important for development of improved adoptive immunotherapy approaches for treating tumors and established infectious diseases. TITLE: Acquisition of full effector function in vitro paradoxically i...

Eleven gene 'signature' reliably predicts cancer prognosis

...s is a very consistent and powerful predictor of a short interval to disease recurrence, metastasis, and death after therapy in cancer patients diagnosed with ten distinct types of cancer. This work indicates that the presence of the conserved BMI-1-associated gene expression pathway that exists in a very...

Tiny avalanche photodiodes target bioterrorism agents

...s (PMTs) were the only available technology in the short wavelength UV portion of the spectrum capable of this sensitivity. These fragile vacuum tube devices are expensive and bulky, hindering true systems miniaturization. The APD technology may see further use in the deployment of systems for secure batt...

NHGRI expands effort to revolutionize sequencing technologies

...ion" Investigators from this group will hybridize short DNA probes to genomic DNA fragments to determine sequence information. In addition, they will use optical mapping to create restriction maps to help assemble the genome once it is sequenced. The group will then demonstrate how to combine the sequence...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

... never occurred," Zhong said. But even within that short time, there's a danger of the donated electron jumping back to the photolyase enzyme before the repair is done. Zhong's work has revealed how the water in the pocket performs a critical function at this point. When the photolyase enzyme becomes exc...

Tiny roundworm's telomeres help scientists to tease apart different types of aging

NIEHS launches website with information for assessing environmental hazards from Hurricane Katrina

... and medical facilities, that will help assess the short and long effects of Katrina on the Gulf region. "With a disaster of this magnitude, people need many things, including easy access to science based information so they can make informed decisions to further reduce their risk of harm," said NIEHS Di...

Research casts doubt on circulating stem cells

... green-fluorescent thanks to a genetic addition. A short time later they then discovered green-fluorescent nerve cells in the mice's brains. This appeared to them to be evidence that the stem cells circulating in the blood could actually transform themselves into nerve tissue. It looked like the discovery ...

Researchers find Amchitka seafood safe for now

...ted by the fact that we were able, within the very short single season of work, to add so significantly to the geophysical understanding of Amchitka and its marine environment. I worked with excellent teams from four good research universities." David Kosson, head of the CRESP Remediation Center of Experti...

MicroRNAs have shaped the evolution of the majority of mammalian genes

Solexa and collaborating scientists illuminate the small RNA component of the transcriptome

...cience Foundation, generated more than two million short DNA sequences, known as signature sequences or sequence tags, to identify and quantify both known and novel small RNA molecules. Many regions of the Arabidopsis genome previously considered to be inactive or featureless were found to be sites of cons...

Researchers offer proof-of-concept for Altered Nuclear Transfer

... technique called RNA interference, or RNAi. Here, short interfering RNA (siRNA) molecules are designed to target an individual gene and disrupt its ability to produce protein. In effect, the gene is shut off. Jaenisch and Meissner designed a particular form of siRNA that shut off this gene in the donor nu...
