Discredited Korean embryonic stem cells' true origins revealed
...cells derived from different sources: from embryos produced
by natural fertilization; from embryos produced
by parthenogenesis (through artificial activation of unfertilized eggs); and from embryos created th...
Where broken DNA is repaired
...ound in cosmic rays, such as energetic iron nuclei produced
in accelerators at Brookhaven National Laboratory. The goal is to determine how many double-strand breaks (DSBs) in which both strands of the DNA double helix are severed occur per gray of radiation. (One gray is equivalent to 100 rads, an older un...
Success or failure of antidepressant citalopram predicted by gene variation
...oduced, strengthening their validity. The protein produced
by HTR2A acts as a receptor on brain cells for the chemical messenger serotonin, one of several neurotransmitters that enable the cells to communicate with each other. The discovery that a variation in a serotonin-related gene could affect response t...
Phase II study of therapeutic vaccine shows efficacy in patients with metastatic colorectal cancer
... protein is rarely found in normal tissues, but is produced
at high levels by a wide range of human cancers, including colorectal, renal, gastric and ovarian. The production of 5T4 has been associated with cancer metastasis and poor prognosis for patients. Typically, the immune system doesnt pay attention ...
Handicapping tuberculosis may be the way to a better vaccine
...investigator William R. Jacobs and colleagues have produced
a genetically altered strain of tuberculosis (TB) that elicits a stronger immune response than the current vaccine, bacillus Calmette-Gurin (BCG). The new vaccine improves survival of infected animals and may help put scientists on track to replace B...
New grants bolster efforts to generate faster and cheaper tools for DNA sequencing
... The resulting data could be linked to information produced
by other emerging sequencing platforms....
Measuring nectar from eucalypts
...here has been no information on how much nectar is produced
by retained trees or young trees regrowing after l...history nor tree size. When the amount of nectar produced
by whole forest stands is estimated on the basis of individual flower measurements and counts of flo...
Under magnetic force, nanoparticles may deliver gene therapy
...d from the particle, entered the cell nucleus, and produced
enough adiponectin to significantly reduce the proliferation of new cells. In a practical application, such nanoparticles could be magnetically directed into stents, the tiny, expandable metal scaffolds inserted into a patients partially blocked ve...
Chickens dieting to help Delaware waterways

more than 280,000 tons of waste. According to recent analyses by David Hansen, UD assistant profes...
Cell damage caused by brushing may help keep gums healthy
...e area of interest is to identify chemical signals produced
by wounded oral cavity cells that could promote gum health. Moreover, the method and/or type of brush might strongly influence the extent of epithelial cell-wounding and subsequent liberation of factors that promote gum health, Dr. McNeil says. In...
New aerogels could clean contaminated water, purify hydrogen for fuel cells
...e and behavior of the gels. The high-energy X-rays produced
by the APS, however, allowed the scientists to take accurate readings of the atomic distances within these disorganized materials. "This is where the APS really excels. It's the only place that has a dedicated facility for doing these kinds of measur...
Insulin grown in plants relieves diabetes in mice; UCF study holds promise for humans
Capsules of insulin produced

Wider buffers are better
...specially critical in controlling amounts of human produced
nitrogen. Scientists at the U.S. Environmental Protection Agency collected data on the buffers along with nitrogen concentration in streams and groundwater to identify trends between nitrogen removal and buffer width, water flow path and vegetation...
Instant steam takes on MRSA
...f seconds, at room temperature and pressure. Steam produced
by the technology is so-called dry steam, generated by the highly exothermic reaction between methanol and hydrogen peroxide. While too expensive to replace the vast quantities of steam used routinely by industry, a reaction chamber the size of a sug...
Using stem cells to help heart attack victims

..., vece, nuck and fute). The sounds were originally produced
by a speaker of American English and then re-synthesized at three different pitch tones, resulting in 18 different pseudo words. The participants were repeatedly shown the 18 pseudo words and a black and white picture representing each words meaning....
Call for EU to launch major project to map out all our proteins
...ld of proteomics aims to discover all the proteins produced
by a given organism. Such a proteome map would bring the possibility of deducing the precise number, and location in the genome, of the genes coding for proteins. This is much more complex than simply mapping the genome from end to end because it inv...
Secondary waste from chemical weapons stockpile disposal
