LIAI scientists make important finding on cytomegalovirus transmission

...al studies with the IL-10 suppression and the OX40 enhancement combined into one treatment. "We tested them separately, but they may well be even more effective when combined," Croft said....

Scientists genetically engineer tomatoes with enhanced folate content

...for the natural addition of folate to diet through enhancement of the folate content of fruits and vegetables." The vitamin is commonly found in leafy green vegetables like spinach, but few people eat enough produce to get the suggested amount of folate. So, in 1998, the Food and Drug Administration made it m...

Wired for sound: How the brain senses visual illusions

...e second illusory flash was also marked by a rapid enhancement of processing in the auditory cortex of the brain. By observing the auditory boost, the researchers could predict when subjects would report seeing the visual illusion of a second flash. "Our results provide evidence that perception of the illu...

Carnegie Mellon University research shows how sensory-deprived brain compensates

...test study is the first to show such an impressive enhancement of brain activity in an animal with sensory loss. Losing sight, hearing, taste, smell or touch are common disabling side effects of traumatic brain injury and stroke. In her study, Barth recorded brain activity in mice with various degrees of whis...

Experience affects new neuron survival in adult brain; study sheds light on learning, memory

... identify a critical period for experience-induced enhancement of new neuron survival in the hippocampus," says Elizabeth Gould, PhD, of Princeton University, who was not affiliated with the study. The hippocampus contains the dentate gyrus. After injecting mice with a chemical used to mark proliferating c...

Drug treatment improves learning in mice with Down syndrome symptoms, Stanford/Packard study shows

...fter some brief, inconclusive studies on cognition enhancement in elderly or mentally impaired people in the 1950s, PTZ has been primarily used for the study of epilepsy in animals. In 1982 the FDA withdrew approval for the use of PTZ in humans because no clear clinical benefit had been established. That is, unt...

Growth factor stimulates rapid extension of key motor neurons in brain

...nfirming that the IGF-1 pathway is critical to the enhancement effect. Experiments with another type of neur...y in CSMN. The researchers also showed that IGF-1 enhancement of axonal growth operates separately from the growth factor's known support of neuronal survival. T...

Proteins necessary for brain development found to be critical for long-term memory

...s of the growth factors were prevented, long-term enhancement of the connections between the brain cells in the reflex circuit normally induced by the shock treatment was also blocked. "We would never have expected that the secretion of these growth factors in response to serotonin would be critical for long-...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

...ons to combat infectious diseases -- immune system enhancement and biocompatible blood substitutes that can be sterilized to avoid costly screening measures, for example. "Whether developing countries choose to build capacity in regenerative medicine themselves or whether they wait to adopt therapies developed...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...norods are arranged at an 86-degree angle. "The enhancement factors are extraordinary," Dluhy said. "And the nice thing about this fabrication methodology is that it's very easy to implement, it's very cheap and it's very reproducible." Tripp said the technique is so powerful that it has the potential to d...

Got inexpensive contrast agent? Milk plays new role in imaging

...e are able to achieve similar bowel distension and enhancement as we see with the commonly used contrast agent, VoLumen,?said Lisa R. Shah-Patel, M.D., a radiology resident at St. Luke’s-Roosevelt Hospital in New York City. “In addition, we found that patients are more willing to drink milk because it is part o...

Snakes' virtual glasses, leopard spots and all-optical transistors

...kind of snake brain firmware - that provides image enhancement as though the snakes were wearing virtual corrective lenses. Because snakes' brains are small, the physicists kept their model of an image enhancing network simple. They discovered that even a crude network dramatically improves infrared imaging - wh...

Researchers unveil strategy for creating actively-programmed anti-cancer molecules

...tional Academy of Sciences, achieved a significant enhancement of the treatment of metastatic breast cancer in an...hese results, the study noted, were a "significant enhancement in the therapeutic efficacy" of the integrin antagonist directly attributable to the chemically prog...

Coming soon: 3-D imaging that flies 'through' and 'around' cancer

...ng. "This one case shows the potential synergistic enhancement of both PET and CT when rendered into three dimensions," said Quon. PET and CT are standard imaging tools that can be used to pinpoint the location of cancer within the body. When PET is used to image cancer, a radiopharmaceutical (such as fluorode...

Drug triggers body's mechanism to reverse aging effect on memory process

...rain cells is enhanced and memory is encoded. This enhancement is responsible for long-term cognitive function, higher learning and the ability to reason. With age, deficits in LTP emerge, and learning and memory loss occurs. Significantly, restoration of LTP was found in the middle-aged rats' brains even afte...

Experimental drug reverses key cognitive deficits, pathology in Alzheimer's

...ecting levels of these enzymes, as a result of its enhancement of M1 receptor activity. The researchers concluded that "the results of the present study show the remarkable therapeutic potential of AF267B in attenuating the major hallmark neuropathological lesions relevant to AD and in restoring cognitive func...

HIV vaccine takes different tack to boosting immune response

... said Chen. "In most cases, we found a significant enhancement in both antibody and T-cell response by inhibiting SOCS1." Chen hopes this immunization approach of inhibiting SOCS1 will help develop more effective prophylactic as well as therapeutic vaccines. Therapeutic vaccines may contribute to the long-term ...

Activation of a protein solidifies fear memory in the brain

She said enhancement of reconsolidation may contribute to the development of maladaptive memories in psychiatric disorders such as post-traumatic stress disorder, depression and drug addiction. "Additionally, the ability to strengthen memories by retrieval has important...

Molecular cabal contributes to stroke damage

...ted NMDAR or CaMKII prevented the ischemia-induced enhancement of ASIC sensitivity, as well as neuronal death. "In summary, our report provides a functional linkage between NMDAR-mediated exitotoxicity and ASIC-mediated acidotoxicity induced by ischemia, which is known to cause excessive glutamate release and a...
