Old memory traces in brain may trigger chronic pain

... be reduced 30 percent – their emotional suffering completely disappeared. Rat are nocturnal animals that prefer to be in the dark and are averse to bright light. Researchers placed the rats in a two-compartment chamber –- one side light, one dark. When the rats were in their preferred dark side, scientist...

Caribbean frogs started with a single, ancient voyage on a raft from South America

... species from throughout the Caribbean islands was completely unexpected," Hedges said. To make their discovery, the researchers sequenced the DNA of nearly 300 species of Caribbean, Central American, and South American frogs and used three mitochondrial genes and two nuclear genes in their study, building t...

Study shows big power of small RNAs, not just proteins, in halting cancer

...53 uses miRNAs to stop tumor cell growth reveals a completely new dimension of this critical cancer fighting pathway and its ability to trigger the genetic death of cancer cells. “Our findings certainly lead to a deeper understanding of a critical tumor suppression mechanism but also may provide insight into ...

Longer treatment benefits sleep apnea patients

...g sleep, causing breathing to be difficult or even completely blocked. The CPAP device is worn while the patient sleeps and works by blowing just enough air into the nose to keep the patient's throat open. Because they often find the CPAP device cumbersome, many patients do not use it consistently or for lo...

Physicist cracks women's random but always lucky choice of X chromosome

...a small number of women who unusually don’t have a completely random distribution of X chromosomes but the explanation may have much wider implications as at least 10% of our genes may behave in similar ways as mechanism that "chooses" between X chromosomes. Examples of this range from the immune system to our ...

Progress toward an antitumor vaccine

...proach is that such sugar-containing compounds are completely ineffective at stimulating the immune system to form antibodies. “Immunization is only successful if the vaccine is anchored to an immunizing carrier protein by means of a spacer,” explains Kunz. This would be very easy to accomplish with polysacchar...

Reconstructing the biology of extinct species: A new approach

Ice Age extinction claimed highly carnivorous Alaskan wolves

... connected during that time period. That they were completely unrelated to anything living was quite a surprise,” Leonard said. The result implies that the Alaskan wolves died out completely, leaving no modern descendents. After the extinction, the Alaskan habitat was probably recolonized by wolves that sur...

New vaccine prevents CMV infection and disease in mice

...evelopment of disease when the virus is present by completely disarming the virus’s ability to replicate and establish a persistent infection. The work is currently online in advance of publication in the July issue of Journal of Virology. “Our approach generates an immune response that is different from th...

Skimmed milk -- Straight from the cow

...ay that the discovery of these rogue milkers could completely revolutionise the dairy industry. Ed Komorowski, technical director at Dairy UK says that the New Zealand approach could be used to breed cows that still produce full-fat milk but with only the good fats, which could swing things back in favour of fu...

Avian influenza survivors' antibodies effective at neutralising H5N1 strain

... the amount of virus found in the lungs and almost completely prevented the virus reaching the brain or spleen. In those people in Vietnam who died from the H5N1 strain, the virus was found to have spread from the lungs; this was not the case in those who survived. "We have shown that this technique can work...

Detecting cold, feeling pain: Study reveals why menthol feels fresh

... to rest. As the mice lacking the gene were not completely insensitive to cold -- they avoided contact with surfaces below 10 degrees C, though with reduced efficiency -- the next step, says Julius, will be to illuminate this residual aspect of cold sensation. The finding is the latest of a series of disc...

Scientists discover 5 new species of sea slugs from the Tropical Eastern Pacific

Was collected from the Bahia de Santiago, Colima in Mexico and is named for Roberto Chavez, who provided assistance during fieldwork and suggested dive sites. Cuthona destinyae came...

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

...ghting response to the infection, which lessens or completely avoids the symptoms of illness." Unlike some other diseases, getting vaccinated following exposure to smallpox could provide protective effects. For example, for the flu vaccine to work, people need to get vaccinated before being exposed to influe...

Mice with a migraine show signs of brain damage

... severe injury, or when blood flow to the brain is completely stopped, such as during a heart attack. “In mice, the damage from these episodes looks exactly like the damage that occurs to the brain from repeated TIAs, or transient ischemic attacks,?said Takano. “It’s long been known that patients having a mi...

Salk scientists hammer out a pathway that promotes muscle cell survival in mice

...lt. "We’ve discovered that SIK1 provides a completely unexpected link between two important mechanisms of gene regulation, CREB and HDAC, and have shown that this pathway plays a major role in maintaining normal muscle function," said Berdeaux. "Now it remains to be seen how this pathway works in muscle...

Scripps research team sheds light on long-sought cold sensation gene

..., suggesting their ability to sense this range was completely disabled without the gene. Normal mice, on the other hand, found cold temperature unpleasant, reliably avoiding cold temperatures in favor of warmer areas. "It’s pretty amazing that one gene could impact thermal sensation this much," says Ajay Dh...

Peramivir protects mice from lethal H5N1 infection

...ercent. The single intramuscular injection did not completely inhibit H5N1 virus replication in the lungs and spleen, but did decrease the spread of virus to the brain. "Peramivir should be given as soon as H5N1 infection is suspected, since onset of symptoms in infected humans can be delayed," said David A...

Molecule that destroys bone also protects it, new research shows

...is new information has forced scientists to revise completely how they view their favorite disease. Everyone now has to rethink the causative mechanism." Gaffen said IL-17 likely would be toxic if given systemically, so it may not be a therapeutic candidate to increase immunity. But inhibitors of IL-17 are...
