Scratch no more: Gene for itch sensation discovered

...t drugs can be used to suppress the itch sensation without affecting the pain sensation, according to Chen. And because pain can be an important protective cue that warns of danger, it may be a distinct advantage to have an anti-itch medication that doesn't compromise our pain-sensing capability. GRPR had b...

FDA sees nanotech challenges in every product category it regulates

...suring the benefits of nanotechnology are realized without undue risk,” Dr. Maynard said. “FDA is limited in its oversight of nanotechnology by the dearth of available risk research data on nanomaterials. Because the agency is resource-starved, there are scant funds for FDA to conduct its own regulatory-rel...

Cellular message movement captured on video

...-fluorescence-labeled traces of cytoskeleton. Even without video evidence, scientists have confirmed over the past 10 years that higher organisms use paxillin as a transmitter of locomotion and gene-expression signals from several classes of growth-factor receptors to the nucleus. Cancer researchers are e...

Agent slows aging in mice

... to be good for mice, it won’t be possible to tell without careful studies of humans whether NDGA is beneficial, useless, or harmful to people. Occasionally, something that is harmless in mice turns out to be highly toxic for people,” Miller cautions, adding that the Food and Drug Administration doesn’t eva...

Cells re-energize to come back from the brink of death

Brain inflammation may be friend, not foe, for Alzheimer's patients

...rdrive had only about half as many plaques as mice without the over-active IL-1beta. Through extensive experiments, the team showed that the mice simply weren’t making fewer plaques, but rather that the body was better at getting rid of the plaques. The team suspects the involvement of brain cells called ...

Releasing fish for the future

Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model

...ated to GDNF. Control mice received only the virus without the GDNF or neurterin genes inserted. Four weeks after the treatment, rats administered HSV-GDNF exhibited significant recovery of intracavernous pressure (ICP) and systemic arterial pressure (AP) compared with rats treated with the control virus...

Hormone helps mice 'hibernate,' survive starvation

...to control the use of fat as energy. Starving mice without PPAR-alpha become hypoglycemic and quickly die. ... to see if we can get some benefits of eating less without actually eating less,” he said. Manipulating the PPAR-alpha-FGF21 signaling pathway might ultimat...

Research team identifies new Alzheimer's gene

...more genetic markers in the DNA of people with and without Alzheimer’s disease than ever before has enabled researchers to identify a common gene that appears to increase a person’s risk for developing Alzheimer’s disease. The finding, announced today by researchers at the Translational Genomics Research Ins...

How to lose weight and not go hungry: HU researcher develops drug that mimics feeling of 'fullness'

...ractical weight loss solution for the obese person without his having to feel hungry. For this development, Yaniv Linde, a 32-year-old Ph.D. student of Prof. Chaim Gilon in the Department of Organic Chemistry at the Hebrew University, has been named a first place winner of a Kaye Innovation Award, which ...

Loss of stem cells correlates with premature aging in animal study

...explains that in the current study the mouse cells without ATR had an overwhelming amount of DNA damage and could not contribute to tissue renewal; nevertheless, the 10 to 20 percent of cells that escaped ATR deletion were able to reconstitute tissues in the engineered mice, at least initially. “Think o...

Studies to find better ways to preserve human eggs, ovarian tissue under way

... “That is why we have tried to develop technology without freezing,” says Dr. Song, who has pioneered use of... eggs – which last about 24 hours outside the body without preservation – would reduce the cost and logistical issues of coordinating donor eggs. “The long-...

New study finds genetically engineered crops could play a role in sustainable agriculture

...uite good. But when Bt crops are compared to crops without insecticides, there are reductions of certain animal groups that warrant further investigation.” What is clear is that the advantages or disadvantages of GM crops depend on the specific goals and vision for agroecosystems. As NCEAS Director, Jim...

Brightening prospects of using fluorescent nanotubes in medical applications

An example of the possible medical applications of nanotube fluorescence is a collaboration that Hertel and Associate Professor of Biomedical Research Duco Jansen are planning. Jansen h...

Salty oceans provide early warning for climate change
