UCSF brain tumor vaccine trial shows promising results

...Antigenics, the Massachusetts biotech company that produces the vaccine from the patient’s tumor tissue. Altogether, Canagelo has now received seven injections of vaccine. “My most recent MRI showed that there is no tumor,?Canagelo said. “I haven’t had any side effects from the treatment, and I’m getting s...

Researchers develop technique for bacteria crowd control

... cell containing a colony of bacteria. The current produces electrolysis that changes the local pH level in the vicinity of the electrodes. The bacteria, uncomfortable with the changes in pH, swim away from the electrodes and ultimately congregate in the middle of the experimental cell. Concentrated bacteria...

Researchers create artificial enzyme that mimics the body's internal engine

...ructure called the electron transport chain, which produces adenosine triphosphate (ATP), a molecule that is the source of the cell's energy. The transport chain is made up of a series of proteins known as electron carriers. Each carrier receives electrons from the preceding one, then transfers them down the ...

White blood cells in lung produce histamine seen in allergies

...They induce neutrophils to produce the enzyme that produces histamine." Individual neutrophils produce much less histamine than individual mast cells, says Caughey, but "because pus contains millions if not billions of neutrophils, the overall amount they make is very considerable." The neutrophil-histami...

Selective marker found to indicate aggressive form of breast cancer

...ughter cells. "Normal basal epithelial tissue produces nestin, but basal epithelial tumors produce a tremendous amount of nestin, which likely represents an abnormal expansion of the basal epithelia." DiRenzo said. "If it is indeed specific to regenerative cells, then it will make for an excellent diagno...

Racing neurons control whether we stop or go

...tical models can be used to discover how the brain produces thought and action." Vanderbilt psychologists Leanne Boucher, Thomas Palmeri, Gordon Logan and Schall published the findings in the April issue of Psychological Review. The new paper uses physiological data collected in Schall’s laboratory to ...

Researchers find hepatitis A and hepatitis C attack same protein to block immune defenses

...by direct contact with infected blood. Hepatitis A produces fever, nausea and abdominal pain that can last for weeks, but rarely lead to death; hepatitis C, by contrast, often spends decades quietly damaging the liver, until a victim’s only hope for survival is an organ transplant. According to researchers a...

How genetic malfunction causes a form of retardation

... of mental retardation called Noonan Syndrome (NS) produces an imbalance in the genesis of two types of cells in the developing embryonic brain. This imbalance, they theorize, could explain how the genetic abnormality gives rise to the neural pathology of the disorder. More broadly, they said, the new insight...

Rewarding fat rats

...igated the role of leptin, a hormone that the body produces in proportion to the amount of stored fat. A person who eats a lot during holidays, for example, will make more leptin than a person who sticks to a stricter diet. In work carried out by Shizgal's team, chubby lab rats were put on a diet to reduc...

Long-lived deep-sea fishes imperiled by technology, overfishing

...luding orange roughy and oreos, an individual fish produces thousands of eggs ?most of which die through predation or starvation. "One of the things we need to know more about is how the fish larvae get transported," Heppell said. "We don't know whether fish from different seamounts are genetically distinc...

...g," Llewellyn-Jones said. "The ATSR instrument produces data of unrivalled accuracy on account of its unique dual view of the Earth’s surface, whereby each part of the surface is viewed twice, through two different atmospheric paths," Llewellyn-Jones added. "This not only enables scientists to correct for...

Latest research to be revealed at Canberra briefing The Skelding project, and other ground-breaking research, will ...

ASU researchers test antibacterial effects of healing clays

...prosy and tuberculosis, the Mycobacterium ulcerans produces a toxin, lesions, and destroys the fatty tissues under the skin. "The toxin is immunosuppressant; the patients feel no pain and the body mounts no response to infection. It leads to disfigurement, isolation, not unlike that seen in leprosy," Hayde...

U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen
