AACR Favors 'full spectrum of stem cell research biology'

...arch on human embryonic stem cells may extend this promise by providing a transplantable cell source that avoids the problems of immune rejection. # Cancer stem cells have been described as the progenitors of breast, prostate, brain and other malignant tumors, raising the prospect of eliminating tumor recur...

Discovery of T-cell 'traffic control' boosts new drug promise

...ing excess S1P action. The research also shows the promise of similar strategies to prevent rejection of transplanted organs and tissues without compromising essential immune defenses. The emerging view brings together research findings on S1P's effect on both the immune system and the blood-circulating vas...

Nanowires can detect molecular signs of cancer, scientists find

...curacy and sensitivity, the minuscule devices also promise to pinpoint the exact type of cancer present with a speed not currently available to clinicians. A paper describing the work will appear in October in the journal Nature Biotechnology and is now posted on the journal's web site. "This is one of the...

'Shifty-eyed' Monkeys Offer Window Into Brain's Social Reflexes

...direction.' Platt said that the finding offers the promise of a manipulable animal model of 'social attention' -- how the human brain assesses the goals and intentions of other humans and responds to them. 'It's been long known what parts of the human brain are involved in identifying and recognizing other i...

Gene therapy to lower blood pressure just enough

...t-weight/body-weight ratio. For this reason it has promise in reducing some of the organ damage that occurs as a result of high blood pressure. One question that remains is whether the body will accept repeated injections of the viral vector or whether its immune system eventually react against it, said O'M...

For first time, brain cells generated in a dish

...hers describe a cell culture method that holds the promise of producing a limitless supply of a person's own brain cells to potentially heal disorders such as Parkinson's disease or epilepsy. "It's like an assembly line to manufacture and increase the number of brain cells," said Bjorn Scheffler, M.D., a ne...

Elevated temperature enhances success of viral cancer therapy

...r to the one that causes the common cold has shown promise in clinical trials. Now, new research suggests that fever might be a useful weapon in the fight as well. The study, published in the July issue of Cancer Cell, demonstrates that tumor cells are even more sensitive to viral therapy after they have bee...

Researchers devise new technique for creating human stem cells

... reason, many researchers believe stem cells offer promise for creating populations of specialized cells that...ogy." Eggan added that the most realistic current promise of the fusion technique is in studying the machinery of genetic reprogramming of somatic cells by em...

OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

...mes." While the research demonstrates vitamin C's promise for counteracting the effects of nicotine on lung function, scientists note that vitamin C did not counteract other negative health impacts of smoking during pregnancy such as abnormal brain development and decreased body weight. The scientists also ...

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

...here was still a lot of work to be done before the promise of these early results could be translated into reality. "Embryoid bodies can differentiate into all sorts of tissue types, so we need to choose the cells that are going to develop into PGCs and then work out how we can encourage them to grow into ga...

Scientists turn tobacco against cancer

... can target and hunt down cancer cells. The plants promise to provide a cheaper, faster method of producing anticancer antibodies, raising hopes that the technology can one day be used in humans. Scientists, led by Hilary Koprowski, M.D., professor of microbiology and immunology and director of the Biotechn...

Novel compounds show promise as safer, more potent insecticides

...w classes of broad-spectrum insecticides that show promise as a safer and more effective way to fight pest insects that damage food crops. The insecticides, which represent the first synthetic compounds designed to activate a novel insecticide target called the ryanodine receptor, may also help tackle the gr...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

... in soils and aquatic sediments, have demonstrated promise as cleaners of toxic spills and generators of energy. They are anaerobic bacteria (living without oxygen) that use metals to gain energy the way humans and other organisms use oxygen. They are distributed throughout the world in a wide variety of soi...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...ater pH conditions." Fe-TAMLs already have shown promise in killing a simulant of a biological warfare agent (anthrax), reducing fuel pollutants, treating pulp and paper processing byproducts, and detoxifying pesticides. A major goal is to develop Fe-TAMLs as a safe, cost-effective means of global water de...

Montreal researchers probe the genetic basis of memory

...y, the scientists believe their discovery may hold promise in the treatment of a variety of illnesses linked to memory. "The discovery of the role of GCN2 in long-term memory may help us develop targeted drugs designed to enhance memory in patients with memory loss due to illnesses such as Alzheimer's diseas...

Researchers grow stem cells from human skin

...r bodies is made up of fat, muscle and bone." The promise of stem cells lies in their ability to develop into specialized types of cells and to replicate themselves. Scientists hope to harness the potential of stem cells and use them to replace damaged cells and tissue in conditions such as spinal cord inju...

NCI Researchers Confirm the Effectiveness of Immunotherapy Approach to Treating Melanoma

...the tumor, then reintroduced into the patient. The promise of this therapy is that a patient's own immune system can be used to effectively treat existing tumors. Results are reported in the April 2005 issue of the Journal of Clinical Oncology. "These results represent confirmation of our original findings ...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...500 meters below surface, research that holds huge promise for biologists. Says Dr. Ron O'Dor, Chief Scientist of the Census: "DNA research made possible through this project may allow us to reconstruct the history of marine evolution." More than scientific curiosity drives this enterprise. The planet's po...

New vaccine means bye-bye to bacteria in the lung

...eudomonas aeruginosa is therapeutic in mice offers promise for patients with cystic fibrosis or other disorders that prevent them from effectively fighting off respiratory tract infections. ...
