Study hints at role of stem cell genes in testicular, breast cancers

...es may play a role in the development of tumors or serve as valuable markers of tumor progression, the researchers say. As such, the genes ultimately could lead to new targets for therapy or markers for diagnosis. A next step, according to the researchers, will be to "dig deeper" to determine the function...

Researcher says flu responders can learn from 1918 epidemic

... What happens if the hospitals which traditionally serve the needs of the inner city begin to run out of beds? Do we think that people will sit pat in the projects and poor neighborhoods of our country and watch as their family and friends, their very communities, die? I don't see why there wouldn't be ci...

Restaurant seafood prices since 1850s help plot marine harvests through history

Chernobyl: The true scale of the accident

...finement covering the existing shelter that should serve for more than 100 years, starts in near future. The new cover will allow dismantlement of the current shelter, removal of the radioactive fuel mass from the damaged unit and, eventually, decommissioning of the damaged reactor. A comprehensive strate...

Plant wounds trigger bacteria

...ll tumor synthesize compounds called opines, which serve as food for the bacterial invaders. The discovery may lead to a cure for crown gall disease, which takes a large economic toll on fruit and wine-grape crops each year. "Mutant forms of Agrobacterium are also widely used in agricultural biotechn...

Retinal scans eyed for New Mexico show cattle

...equired to submit hair samples for DNA analysis to serve as a permanent means of identification. "DNA analysis is costly and requires a complex laboratory procedure that takes time," he said. "Also, hair samples have been lost in transit." Among the show cattle, researchers found that the retinal scans pr...

Mouse genome much more complex than expected

...A copies derived from the same page, which in turn serve as a blueprint for different proteins. Only twice as many genes as a threadworm? This observation might also explain the big question why mammals only have about twice as many genes as threadworms, which have a much simpler structure. 'Our study c...

Max Planck researchers make a breakthrough in plant stem cell research

...on, and thereby identified four genes, which might serve as a mechanistic connection between plant hormones and the genetic regulatory elements in meristem. The researchers in Tübingen used gene expression analysis to show that the genes ARR5, ARR6, ARR7 and ARR 15, "Arabidopsis Response Regulators", are...

Shorter colds, milder flu may follow from newly revealed immune mechanism

... in the course of respiratory viral infections can serve to protect macrophages from an untimely death. Their report will appear in an upcoming issue of Nature Medicine and is available on October 9 at the journal's website. "If the macrophages were to die, the infection would spread further," says senior...

Clocking in Pillow Time without the Pillow

... counteract the effects of sleep deprivation could serve as substitutes. In a new study, Sam Deadwyler and colleagues have explored this possibility by giving dog-tired rhesus monkeys a drug shown to improve the functioning of alert brains. They found that sleepy monkeys taking the drug performed tasks bet...

Noise And Delays Explain Why Some Genes Oscillate In Activity

In a new study, Sam Deadwyler and colleagues have explored this possibility by giving dog-tired rhesus monkeys a drug shown to improve the functioning of alert brains. They found that sleepy monkeys taking the drug performed tasks bet...

'Sharp' older brains are not the same as younger brains

...ptic change," Gallagher said. "This 'switch' could serve the same purpose ?storing memories ?but through a different neurochemical device." ...

Langerhans cells regulate immune reactions in the skin

...n generally assumed that the Langerhans cells only serve to warn the immune system of skin pathogens. According to the study, featured on the cover of the December 15 issue of Immunity, Langerhans cells are not required and, in fact, inhibit or modulate immune responses in the skin. Daniel H. Kaplan, M....

New study identifies key gene in development of connections between brain and spinal cord

.... Mice were used as the animal model because they serve as a powerful genetic representation of human brain circuitry. The major finding of the study was that in developing mice that lack Fezl, normal connections to the spinal cord failed to form. Instead, the brain cells that usually form the spinal co...

RNA splicing occurs in nerve-cell dendrites

... and redundancy of the nervous-system proteins may serve to help maintain the system over a lifetime. However, failure in protein regulation or proper expression in neurons may give rise to cognitive dysfunction. "Most neurodegenerative and psychiatric illnesses exhibit dendrite dysfunction, therefore, the...

Serious adverse reactions to smallpox vaccine appear to be limited

... vaccine safety monitoring and response system can serve as an effective model for vaccine campaigns that may occur in response to public health emergencies. Unique aspects included rapid detection, investigation, and response to rare and potentially serious adverse events. Our report highlights the succes...

Marsupial genome reveals insights into mammalian evolution

...inpoint regions that remain unchanged because they serve a particular purpose. In contrast, comparison of distantly related genes, such as the chicken and human, can be difficult, because the sequences are so different." "Marsupial and monotreme genomes fill this gap. They are easily aligned with placenta...

Stem cells from muscles can repair cartilage

... author also notes that patients could potentially serve as donors to themselves, since the current study used MDSCs from juvenile rats and other studies have shown such transplants to be problematic in adults. She concludes: "Thus, further work is warranted to determine the chondroprogenitor potential of ...

You will remember this

... College London) can now tell how well memory will serve us before we have seen what we will remember. Scans of brain activity, published online in the journal Nature Neuroscience, indicate that the brain can actually get into the 'right frame of mind' to store new information and that we perform at our ...

Melanoma vaccine strategy shows promise in laboratory experiments

...study. Indeed, such prepared dendritic cells might serve as the basis for a treatment vaccine that could be taken into human clinical trials. Herlyn is senior author on the Cancer Research study. The lead author is Rajasekharan Somasundaram, also at Wistar. The additional Wistar coauthors are Rolf Swoboda...
