New science of metagenomics 'will transform modern microbiology'

...n Genome Project is both justified and necessary," added committee co-chair James M. Tiedje, University Distinguished Professor of Microbiology and director of the Center for Microbial Ecology, Michigan State University, East Lansing. The goal of the large projects should be to characterize in great de...

Magic Beans -- Anti-obesity soya could help prevent diabetes

...reasons why frozen food manufacturer Birds Eye has added the beans to its range. However, a team of Korean researchers has shown that black soya may be even more potent in rats, and also prevents weight gain (Journal of the Science of Food and Agriculture, February 2007 DOI: 10.1002/jsfa2808). The rese...

Non-GMO solution to seafood allergies

...ey took blood from patients with shrimp allergies, added samples of treated and untreated prawn, and measured how antibodies in the blood reacted. They found that levels of ‘Pen a 1? one of the major allergens, decreased 20-fold after treatment (Journal of the Science of Food and Agriculture DOI 10.1002/js...

Cryoablation -- A new treatment option for some kidney tumor patients

...experience with liver tumor cryoablation when they added kidney tumor cryoablation in 2003. Today’s report contains the largest published results for percutaneous cryoablation patients. Mayo researchers report that not only can this technique be an alternative to surgery, but that in some cases, it has b...

Widely used iron nanoparticles exhibit toxic effects on neuronal cells

...dge regions of damaged neurons. However, when they added nerve growth factor to nanoparticle-laden cells in culture flasks, they observed toxic dose-dependent effects: some cells died, and many of the survivors exhibited a diminished ability to produce neurites. In their experiments, PC12 cells that had ...

NIH neuroscience microarray consortium launches high-throughput genotyping services

... Microarray Consortium today announced that it has added high-density genotyping on both the Affymetrix and Illumina platforms to its list of services. Stan Nelson, the principal investigator at UCLA, says that "adding ultra-high throughput genotyping for its user-base of ~10,000 investigators across the w...

Ape gestures offer clues to the evolution of human communication

...ney and so on. It's meaning is context-dependent," added de Waal. Looking for further distinctions between species, the researchers found bonobos use gestures more flexibly than do chimpanzees. "Different groups of bonobos used gestures in specific contexts less consistently than did different groups o...

Unique tomatoes tops in disease-fighting antioxidants

...mato juice and concentrated. Italian seasoning was added for taste. The 12 adults participating in the study ate two spaghetti test meals ?one included sauce made from tangerine tomatoes, while the other featured sauce made from the tomatoes high in beta carotene. The participants were asked to avoid to...

Stress hormones may play new role in speeding up cancer growth

... these same drugs affected these tumor cells. They added propanol, a beta-blocker, to the tumor cells and then exposed them to both norepinepherine and epinephrine. With the drug present, the levels of MMP-2, MMP-9 and VEGF didn't increase. "This suggests a new approach to possibly fight some cancers ?t...

Microbes compete with animals for food by making it stink

Gene key to taste bud development identified

...on into the animals' chromosomes. She selected the added gene for its capacity to produce a special protein, called enhanced green fluorescent protein, that glows green when exposed to ultraviolet light. "When we shine light on tissue from these animals, any cell that is expressing SOX2 will fluoresce, o...

Encouraging results in pancreatic cancer research

... the presence of a control peptide." Dr. Pincus added that this peptide and its parent peptide, called PNC-27, are lethal to a wide variety of human cancer cells, besides pancreatic cancer, including colon, breast, cervical and bone (osteogenic sarcoma) cancers. These peptides kill cancer cells that do ...

Molecular atlas provides new tool for understanding estrogen-fueled breast cancer

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

...the enzyme’s addition site, just after it had been added to the RNA transcript. Later X-ray structures revealed the transcribing complex with the addition site available for entry of a matched NTP. Those crystals uncovered a second NTP-binding site on the transcribing enzyme, dubbed the entry site. While...

Stem cells engage in dialogue with the cells that regulate their futures

...opulations of cancer stem cells." Ruohola-Baker added that stem cells hold high hope in regenerative medicine: tapping into the ways cells repair the body to create therapies to fix or replace injured tissues. She mentioned that it is thought that most, if not all, adult tissues contain stem cells. T...

A valuable fly for research into disease

...rt disease is another topic that has recently been added to the list of diseases studied using Drosophila. Rolf Bodmer, from The Burnham Institute in the US, has begun to use this model to study arrhythmias and heart failure. His presentation "Arrhythmias and cardiac failure: the Drosophila model of congen...

Intravenous gene therapy protects normal tissue of mice during whole-body radiation

...posure to whole-body irradiation." Dr. Greenberger added that intravenous administration could potentially offer wide-reaching protection to the public in the event of a terrorist attack since experts believe a significant number of the population would die within 30 days of receiving a large dose of radia...

To slow AIDS in Russia, treat HIV-positive addicts, Stanford study says

To understand how antiretroviral therapy could affect HIV transmission in Russia, Owens and Brandeau, along with doctoral student Elisa Long, created a computer...

Molecules in blood foretell development of preeclampsia

...igh levels of only one or the other." Dr. Levine added that detecting high levels of both soluble endoglin and sFlt1 early in pregnancy might be especially helpful in predicting the later development of preeclampsia. Detecting high levels of these molecules might also help in distinguishing preeclampsia...
