Wisconsin researchers identify sleep gene

...prolonging wakefulness. "This research offers the possibility of developing a new class of compounds that could affect potassium channels in the brain rather than other brain chemical systems targeted currently," says lead author Dr. Chiara Cirelli, assistant professor of psychiatry at UW Medical School. UW-Ma...

Norovirus, AIDS vaccine and Hepatitis Virus

...bility to cause disease. DNA vaccines offer a new possibility for treatment. The have the advantages of safety, ...," say the researchers. "These results suggest the possibility that interferon lambda may be therapeutically useful in the treatment of chronic HBV or HCV infectio...

Discovery Promises Simpler Therapy for Sickle Cell Disease

... the researchers said. The findings also raise the possibility that defective nitric oxide processing by red blood cells may represent a new class of blood diseases. Patients with sickle cell disease have an abnormal form of hemoglobin. In the late 1990s, Stamler's team discovered that, in addition to its role ...

Researchers find new genes necessary to make embryo

...es of genes showing partial penetrance suggest the possibility of a general architectural motif in genetic networks," said Fabio Piano, an NYU biologist and lead author of the study, "in which genes in critical positions consist largely of older components while new functions added later provide additional layer...

Strongest proof yet found for prion hypothesis

...ly in a test tube. Such an approach eliminates the possibility that some other agent might be causing the disease. In a paper scheduled to appear in the journal Cell on April 21, the UTMB researchers describe the use of a method they developed called "protein misfolding cyclic amplification" (PMCA) to vastly ac...

Same-Sex Mating Discovered in a Toxic Fungus

...minantly harbor a single mating type, reducing the possibility of normal fungal sexual reproduction." The potentially life-threatening fungus C. neoformans invades the central nervous system to cause disease, most commonly in immune-compromised patients such as organ transplant recipients and cancer patients --...

Different microarray systems more alike than previously thought

...Bloomberg School of Public Health. "Now we see the possibility that it may not make much difference as long as th...bility and some did not, and no study explored the possibility that a laboratory's methods of using a particular system affected the results. "Given the amount of...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...d other elephant experts have begun to explore the possibility that the Thai elephants were responding to these p...ford, O'Connell-Rodwell has been investigating the possibility that newborns with severe hearing loss could have their hearing improved by exposure to vibrational ...

New tumor-suppressor gene discovered

Turning viruses into allies against cancer

...the tumor site," said Blechacz. "This provides the possibility of enhancing the therapeutic effect by co-treatment with therapeutic radioactive iodine." Future studies should help scientists evaluate the efficacy and optimal delivery system of their radio-virotherapy vector. "We expect this work will take anot...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...assachusetts. "In the Gulf of Mexico, there's the possibility that hypoxia could occur at a local scale, which could be devastating to the shrimp and shellfish industries," Matson said. "Shrimp fisheries are very important economically, and they're already under a lot of stress from overfishing and aquaculture....

Oldest fossil human protein ever sequenced

...y of Sciences (PNAS). "This research opens up the possibility of getting detailed protein information from past ... DNA rarely survives, this new method opens up the possibility of determining these relationships in much older fossils which no longer contain DNA. The research ...

Could microbes solve Russia's chemical weapons conundrum?

...ssian Academy of Sciences in Puschino examined the possibility of using P putida to transform the toxic by-products contained in reaction masses (RMs) that arise when mustard is destroyed by chemical detoxification (a procedure developed in response to the CWC). Currently, incineration or a process called bitum...

Gladstone investigators discover how resting T cells avoid HIV infection

...n the chromosomes that might lead to cancer. "The possibility of exploiting the natural and potent antiviral properties of A3G to control HIV infection is very exciting," says Greene. "We have learned a great deal from our studies of how the resting CD4 T cell resists HIV. Now, the challenge is for scientists a...

Of mice and men's (and women's) contraceptives

...perm and eggs," explains Hecht. "An equally likely possibility is that the absence of MSY2 disrupts the timing of how specific mRNAs are used during germ cell differentiation. As cells become mature sperm, there's a precise order of synthesis of many essential proteins needed to create functional gametes. We thi...

Scientists discover how Ebola virus infects cells

...r Anthony S. Fauci, M.D. "These findings raise the possibility of a broad-spectrum antiviral therapy that could be effective against multiple hemorrhagic fever viruses." Senior author James M. Cunningham, M.D., of Brigham and Women's Hospital and Harvard Medical School in Boston, and his colleagues discovered t...

Retrovirus struck ancestors of chimpanzees and gorillas millions of years ago, but did not affect ancestral humans

... Asian apes may have been resistant to it. Another possibility is that some early humans may have carried the virus, but eventually died off. Researchers also don't know the impact the virus had on the primate species it did affect. They found many copies of the virus in the genomes of both species, but only a ...

Microscopes at microscopic size

...ells react to a drug. The biochips also raise the possibility of a micro-laboratory, the size of a credit card, which would be able to perform medical diagnostics, improving patient treatment by reducing the number of hospital visits needed for tests. The initial research has led to the creation of a spin-out ...

Molecular thermometers on skin cells detect heat and camphor

Investigations into this possibility are ongoing. ### To read the article, "Impaired Thermosensation in Mice Lacking TRPV3, a Heat and Camphor Sensor in the Skin" by Aziz Moqrich, Sun Wook Hwang, Taryn J. Earley, Matt J. Petrus, Amber N. Murray, Kathryn S. R. Spencer, Mary Andahazy, G...

Remote control flies? Fly behavior controlled by laser light

... in spinal cord trauma, although he notes that the possibility is "far-fetched" at the moment. The remote control is based on the idea that specific nerve cells could be equipped with molecular "receivers" that allow them to recognize an outside signal like a laser light pulse and translate that signal into the...
