Vaccine for brain tumors shows promising results

...erprint" of the patient's particular cancer and is designed to reprogram the body's immune system to target on...). The UCSF clinical trial is a phase1/2 study designed to establish the feasibility, safety and preliminary efficacy of vaccination in patients with recurr...

Worms produce surprise insight into human fever

..., says Aballay. He also points out that new drugs designed to activate HSF-1 are already in clinical trials for treating neurodegenerative diseases. “Our work opens the possibility of using co-inducers of HSF-1 to boost immunity to treat infectious diseases and immunodeficiencies,?says Aballay. ...

New dyslexia theory blames 'noise'

...udy. The new study in Psychological Science was designed to replicate visual tests on motion perception from seminal experiments in the 1970s, with the addition of variable external noise. It also found no magnocellular deficit. "These were the stimuli people used to establish the magnocellular hypothes...

Slow brain waves play key role in coordinating complex activity

...Helen Wills Neuroscience Institute. "Our study was designed to test the idea that the high-frequency oscillations generated by the brain are coupled to the slower theta oscillations. "This coupling is important because the two rhythms have different functions and operate on different spatial scales - a patc...

New HIV statistics indicate increasing toll of AIDS on African American community

... HIV prevention program that has been specifically designed for black MSM. Investing in research to implement...vestment in education and substance abuse programs designed to prevent people from using injection drugs in the first place and help current users to quit, and ...

Altered perception of reward in human cocaine addiction

...ber 18, 8:30 a.m.* Goldstein's experiments were designed to test a theoretical model, called the Impaired Response Inhibition and Salience Attribution (I-RISA) model, which postulates that drug-addicted individuals disproportionately attribute salience, or value, to their drug of choice at the expense of o...

Protein folding: Building a strong foundation

...ion as they should. In the new study, scientists designed and tested a new computational approach that aimed to study proteins with known shapes in order to ascertain which of their parts were the most stable in the face of chemical and thermal fluctuations. "We found that the most stable parts of the fin...

HIV exploits competition among T-cells

...inevitably evolve in the body in a manner that was designed to reduce immunodominance. One such strategy ?polytopic vaccination ?involves giving vaccines against different strains of the same disease simultaneously in different parts of the body. The approach capitalizes on the fact that different lymph nodes...

MIT designs portable 'lab on a chip'

... are so small and cheap to make that they could be designed to be disposable, Bazant said, or they could be made implantable. Potential applications are not limited to military use - imagine going to a doctor's office and getting test results immediately. The technology could also be useful for first respo...

Experimental vaccine protects mice against deadly 1918 flu virus

...er high-level safety and contamination precautions designed to protect the researchers and prevent microorgani... colleagues created plasmids--small strands of DNA designed to express specific characteristics--carrying genes for the virus' hemagglutinin (HA) protein, the s...

PNAS study reveals why organs fail following massive trauma

...ymphocyte expands into army of clones specifically designed to attack the invader at hand. Unfortunately, lymphocytes too are capable of mistakenly destroying human cells. Thus, they have developed quality control mechanisms where they can choose to stop expanding into an army (anergy) or to commit suicide (a...

Innovative movies show real-time immune-cell activity within tumors

...are under these conditions. The researchers then designed a second set of experiments to complement the first. In the first set of experiments, the T cells were varied in two groups of mice while the target tumor cells were uniform. In the second set, the T cells were uniform while the tumor cells varied in...

Stem cell activity deciphered in the aging brain

...h being explored is to treat older rats with drugs designed to mimic the action of compounds called neurogenic factors, which encourage stem cells in the brain to divide, Shetty said. The researchers also are grafting neural stem cells grown in culture dishes into the hippocampus, to stimulate those already p...

Brain protein improves stroke symptoms in rats, even when injected after 3 days

...roke performed significantly better in an exercise designed to test their physical abilities and coordination than rats that had been treated with placebo. ...

Professors to develop hand-held pathogen testing device

...d markers for detection. Hashsham's device will be designed to look for such marker genes. "This technology is rugged and highly parallel; it can analyze lots of marker genes in a lot of samples, together with significantly lower false positives," Hashsham said. He said the hand-held testing device coul...

Researchers find docking sites for glucocorticoid receptor and Hsp90

...randomly introduced GR mutants and 11 specifically designed Hsp90 mutants for their binding and activation abilities. Finding and confirming the two binding sites were boosted by the recently published crystallized structures of both Hsp90 and GR, Darimont said. "Our results suggest that Hsp90 binds GR wit...

Very low birth weight linked to reduced quality of life in pre-school children

...ildren scored consistently lower scores on a scale designed to measure quality of life among pre-school children. Their parents were also much more likely to say that their child had health issues, with 29 per cent reporting a current problem, compared with 18 per cent in the control group. In general, chi...

Researchers discover new gene responsible for brittle bone disease

... treatment for OI does not cure the disease and is designed to reduce the risk of fracture. Only through a better understanding of the disease at the genetic and protein level will we be able to someday offer something better." ...

Living laboratory found on shoreline statues

...arises to assess all facts together in such a well designed ecological experiment. "Creatures like barnacles and mussels prefer habitats that are exposed to the elements but choose optimal positions that allow them to feed in the water column without getting battered by waves and currents. The Gormley st...
