Controversial drug shown to act on brain protein to cut alcohol use

Medicationagainst nicotine addiction is nowadays readily available. However, asimilar and equally dangerous addiction, alcoholism, can't yet becontrolled by drugs. Or can it be? Researchers from the University ofCalifornia in San Diego identified a natural compound able to blockalcohol addiction in rodents...

Plants, animals share molecular growth mechanisms

...t the shape and size of these hairs, or trichomes, readily show when genes affecting actin filaments are askew and causing altered growth. The researchers previously had learned that a large protein complex, known as WAVE, activated ARP2/3, but they didn't know specifically which WAVE protein was the actual...

Purdue proves concept of using nano-materials for drug discovery

...nometer in scale, so they do not allow proteins to readily pass through the membrane but will allow smaller molecules to pass. "This allows us to do separation right in the reactor, which means we can do reactions that could not be done before in such a small device. We can study membrane proteins in a fund...

Placenta Is A Rich Source Of Blood Stem Cells

...in quantity is difficult. The cells don't multiply readily in the laboratory, so they must be harvested from bone marrow by needle aspiration, a painful procedure, or coaxed into the blood and then collected. Both methods yield only a limited number of blood stem cells. For more than a decade, scientists ha...

Devising Nano Vision for an Optical Microscope

...ssfully developed, the imaging technology could be readily incorporated into chip-making and other commercial-scale processes for making parts and products with nanometer-scale dimensions. The wavelengths of light in the visible part of the spectrum greatly exceed nanoscale dimensions. Consequently, the res...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...tor called a replication-defective adenovirus that readily enters cells but doesn't reproduce itself. Ahrens injected the vector carrying the MRI reporter gene into brains of living mice and imaged the MRI reporter expression periodically for over a month in the same cohort of animals. The research showed no...

How an AIDS-Related Cancer Unleashes Inflammation

...Developing countries ?where HIV treatments are not readily available ?will be most likely to benefit from potential new treatments for KS that involve inhibiting cytokine production, Ganem said. “KS has become a less urgent threat in developed countries, because two factors are needed for KS lesions ?viral i...

PCRM develops world's first cruelty-free insulin assay

...ally from Linco. "We hope that by making the test readily available and competitively priced, researchers and medical labs will use it," said Barnard. "We have proven that if researchers are willing to make the effort, there are effective, humane alternatives to animal-based assays and other testing procedu...

PET/MRI scans may help unravel mechanisms of prenatal drug damage

...s show that cocaine and/or its labeled metabolites readily cross the placenta. But the cocaine uptake distribution pattern observed in the fetus was very different from that of the mother. For example, mothers showed rapid uptake and clearance of the drug in the heart, kidneys and lungs, with slower uptake i...

NIH Calls on Scientists to Speed Public Release of Research Publications

...king published results of NIH-funded research more readily accessible to the public, health care providers, educators, and scientists. Beginning May 2, 2005, the policy requests that NIH-funded scientists submit an electronic version of the author's final manuscript, upon acceptance for publication, resulti...

Navigating an integrated yeast network

...alifornia, San Diego, the authors' approach can be readily extended to different types of cellular networks. "[T]he thousands of physical and functional interactions that exist within all cells can begin to be untangled to provide [the] basis for detailed network reconstruction and to elucidate fundamental o...

Infants With Rare Genetic Disease Saved by Cord Blood Stem Cells

...lent source of stem cells, she said. Cord blood is readily available because it is extracted from discarded placentas (afterbirth) following child birth. Adult bone marrow must be harvested from living donors through an invasive surgical procedure. Finally, cord blood cells are less mature than adult bone m...

NASA study finds snow melt causes large ocean plant blooms

.... These bacteria convert a nitrogen-based nutrient readily consumable by plants in seawater, called nitrate, into forms of nitrogen that most plants cannot use. One form of nitrogen that plants cannot consume is nitrous oxide, also known as laughing gas. In the atmosphere, nitrous oxide is 310 times more po...

Roots Engage in Underground Chemical Warfare

... "Current understanding of plant defenses does not readily explain why a pathogen can cause disease in one plant species and not another," says Vivanco. "Our findings will help researchers solve the mysteries of plant disease and immunity." In these experiments, however, root exudates did not kill all of th...
