New technology enables faster, more efficient cell harvest: Cell therapy meeting study

...he Pall system can be used to harvest cells from a broad range of biological samples including peripheral blood, bone marrow and umbilical cord blood. The Company is currently working with several companies in applying its filter harvest system to the development of innovative cell-based therapies in a va...

No-mow grass may be coming to your yard soon

...ability to precisely control plant size would have broad implications for everything from urban forestry to crop and garden plant development. Beyond perpetually short grass, trees could be made more compact for better growth in crowded cities, and berry bushes could be made taller for ease of harvesting. ...

Researchers find protein that silences genes

...involved. "The bottom line is that HDA6 has very broad specificity. It can remove the acetyl groups from multiple histones and from multiple lysines of those histones" said Pikaard. When multiple acetyl groups are on the histones, the genes are turned on, Pikaard explained. When they are removed by HD...

Diabetes research takes wing thanks to long-lived fruit fly

...imply boosting the amount of JNK could have such a broad impact on life span. Then, in another surprise, Jasper and Bohmann showed that JNK targets the same protein as the widely studied insulin receptor, central to human health and to the disease process that underlies diabetes. The finding has opened up...

Fertility hope as study shows eggs survive in older ovaries

In research that could have broad implications for women's fertility treatments, scientists have found that despite their age, female mice have a renewable egg supply in their ovaries. The discovery, by Professor Jock Findlay from Prince Henry's Institute and Associate Professor Jef...

Scientists describe new African monkey genus ?first in 83 years

...led-up tail. They have a "crown" made up of a very broad crest of long, erect hair. Adults make a distinctive, loud, low-pitched honk-bark. An omnivore, Kipunji eat leaves, shoots, flowers, bark, fruit, lichen, moss and invertebrates. These predominantly arboreal monkeys are endemic to Tanzania and known...

Species unique to tidal marshes face threats

...is high, and flooding is frequent. Yet they face a broad variety of threats from human-caused environmental damage, according to an assessment in the August 2006 issue of BioScience written by Russell Greenberg of the Smithsonian Migratory Bird Center and colleagues. Tidal marshes occur in mid to high lat...

Researchers unveil strategy for creating actively-programmed anti-cancer molecules

...ly on breast cancer, these new findings could have broad application in the treatment of a number of other cancers, potentially increasing the efficacy of a number of existing or undeveloped small molecule therapies," said Subhash C. Sinha, Ph.D., associate professor in the Scripps Research Department of M...

Unique dual target specificity of kinase inhibitor key for success against cancer

...ed a new molecule that inhibits proliferation of a broad range of lethal malignant glioma cells in vitro an...ul small molecule kinase inhibitors must display a broad reactivity to effectively attenuate the complex signaling pathways involved in malignant transformat...

Polynesia explorers created worldwide web of scientific knowledge

...Missionary Society, founded in 1795 in response to broad evangelical shock over Polynesian mores, customs and practices, including a few reports of public copulation. LMS missionaries would construct an independent network of knowledge with its own patrons, informants and audience, and they would bring b...

First-ever genomic test predicts which lung cancer patients need chemotherapy to live

...ssing risk, which is imprecise and provides only a broad estimate of a patient's risk, said Joseph Nevins, Ph.D., a professor of molecular genetics at Duke and senior author of the study being reported. Physicians now assign each patient to a clinical "stage" based on the size of the patient's tumor, whe...

Study details hepatitis C ability to block immune system response

...ce the interferon and how the virus can resist the broad spectrum of these antiviral effects." The knowledge gained from fundamental studies such as these could lay the groundwork for the development of potential new treatment strategies for this devastating global disease. ...

Heal thyself: Systems biology model reveals how cells avoid becoming cancerous

... development of new therapeutic agents to combat a broad spectrum of diseases, including cancer, neurodegenerative diseases, and premature aging." Researchers involved in the study agreed that their findings could eventually be used to develop drugs to boost DNA repair in response to environmental toxins ...

FSU biologists uncover mechanisms that shape cells for better or worse

...iological model provided by Drosophila oocytes has broad implications in humans, where, for example, neurons in the brain are designed, or polarized, to interpret information from the sense organs, and intestinal cells are polarized to take up nutrients and move them into the bloodstream," he said. Poult...

'Signature' of chromosome instability predicts cancer outcomes

...elopment -- is predictive of clinical outcome in a broad range of cancer types. Using data on gene expression (activity) from 18 previous studies of cancer, representing six cancer types, they found that this genetic profile, or signature, predicted poor clinical outcome in 12 of the populations studied...

New tiger report release: Tiger habitat down from just a decade ago

...ong-term success is only achieved where there is a broad landscape-level conservation vision with buy-in from stakeholders. "This report documents a low-water mark for tigers, and charts a way forward to reverse the tide," said John Robinson of the Wildlife Conservation Society. "We can save tigers forev...

Study pinpoints protein's role in cancer spread

...our findings may lead to improved treatments for a broad range of cancer types." Welcoming the findings, Professor John Toy, medical director at Cancer Research UK, said: "p53 is a crucial protein that acts as a guardian of the normal cell. Its failure to do its job properly is associated with many typ...

Radiation-killed bacteria vaccine induces broad immune response in mice

Mitochondrial DNA sequencing tool updated

...ike an iPod to music lover, the chip served as the broad technological platform for laboratories to customize arrays more attuned to their research interests. In 2004, Dr. Anirban Maitra and his colleagues at Johns Hopkins did exactly that with the MitoChip v1.0. In addition to nitty-gritty technical in...

Stanford snake venom study shows that certain cells may eliminate poison

...ry arms race." He and Metz suspect that, given the broad range of venoms that have been developed by snakes and other creatures, mast cells probably won't perform as well against every type of venom. "We expect that there will be some snake venoms that either are not affected by mast cells at all or perh...
