Study finds 60 new genes controlled by DNA snippet

...the copying process. Some mutations bring survival advantages and others cause disease. Most known genetic diseases identified to date result from a mutation within a gene that directs protein construction, but that may soon change. "We believe more and more disease-causing mutations will be found within reg...

Predicting successful outcomes in living-donor liver transplants

...rtain benefits. "This novel noninvasive method has advantages in its simplicity, its real-time presentation of results without consuming a lot of time, and its cost-effectiveness," the researchers note. They conclude that being able to predict poor outcomes based on ICG elimination immediately following liver t...

Delft water-purification method promises radical improvement

...anules. The technology therefore offers important advantages when compared to conventional water purification processes. For example, all the processes can occur in one reactor. Moreover, there is no need to use large re-sinking tanks, such as those used for conventional purification. Such large tanks are need...

'Micro-boxes' of water used to study single molecules

... DNA molecule to the other. Water offers several advantages over other methods for containing single molecules, such as attaching them to surfaces or placing them inside liposomes (artificial cells). The water droplets can be held far from any surface that might interfere, can readily encapsulate biomolecules...

New findings offer more complete view of breast cancer gene mutations in US population

...hiladelphia and Seattle metropolitan areas. "The advantages of this study include its large sample size, inclusion of under-studied groups of women and the fact that the results are population based," said one of the study's co-authors, Robert Spirtas, Dr.P.H, former chief of NICHD's Contraception and Reprodu...

New light microscope sharpens scientists' focus

...ncott-Schwartz pointed out that although there are advantages to both imaging techniques, the use of PALM in co...t the molecular scale. Correlative PALM unites the advantages of light and electron microscopy, producing a revolutionary new approach for looking at the cell in ...

Large dinosaurs were extremely hot in their day, UF study finds

...tes with freezing or near-freezing conditions. The advantages of being a 'warm' reptile are that no energy has to be expended to produce metabolic heat to keep warm; in other words, if we were warm reptile-like ectotherms, we would save a lot of money on the grocery bill." In the meantime, the research team c...

Bone marrow may restore cells lost in vision diseases

...ompared to RPE transplantation, there are a lot of advantages if someone's own bone marrow could supply the cells, because it's a ready source and the cells would not be rejected by the patient. Further, if bone-marrow progenitors circulating in the blood could be attracted to sites of disease, surgery could be...

Origen publishes in Nature a robust and versatile method for creating transgenic chickens

...eve a transgenic chicken system offers a number of advantages over either plant or other transgenic animal systems for protein production. Besides the ability to produce antibodies with enhanced cell killing properties, the time from antibody identification to production in eggs is a matter of months, the purif...

Scientists use an 'ice lolly' to find polar bacteria in their own backyard

...ht to be tolerant to cold and could therefore have advantages for snow-making in artificial environments such as ski centres and in waste-water purification. "Selecting for rare microbes that seem to stick to ice has been fun, but now the real work begins to find out what genes are responsible for this attract...

Protowings may have helped bird ancestors cover rough terrain

...s of bipedal protobirds may have provided the same advantages for incline running as have now been demonstrated in living juvenile birds. Their work thus supports a new theory about the evolution of flight in birds. WAIR, which the authors believe to be widespread in birds, appears to offer an answer to the que...

Got inexpensive contrast agent? Milk plays new role in imaging

...lk costs $1.39 per patient. “There are several advantages to milk. Patients are more willing to drink milk than VoLumen, and it costs a fraction of the price,?Dr. Shah-Patel said. “We hope that substituting milk for other contrast agents will reduce the number of people who refuse imaging tests because they...

New biochip helps study living cells, may speed drug development

...stroyed in the process, he said. There are several advantages to retaining live cells, he said, such as being able to conduct additional tests or monitor them as they grow. "The current technology being used in research labs is very slow and difficult," said Porterfield, who believes the new chip could help ...

Study offers innovative profile of enzyme that aids tumor growth

...er. According to the study, one of the primary advantages of the functional proteomic technology employed (activity-based protein profiling) is that it can be used to identify inhibitors for uncharacterized enzymes like KIAA1363. Moreover, because inhibitors are screened against many enzymes in parallel, bo...

Fighting like a girl or boy determined by gene in fruit flies

...stimuli, Tompkins said. "Drosophila have marvelous advantages in terms of genetic tricks," she said, "and flies in many respects behave and respond similarly to humans." The findings provide a welcome guidepost to help enable future research to track down the underlying neural circuitry, said Bruce Baker, a ...

Beyond the book: Software automates access to brain atlases

...he work, download the software and try it out, the advantages will be obvious. He hopes to build on the system to create a general visual interface for neural data, linking brain locations (specified by coordinates) to research results concerning those locations, - "a kind of Google Earth for brain data," he...

New engineered drug may offer prolonged arthritis relief

...foreign substances, and thus they have some unique advantages for biomedical applications, according to the researchers. Also, ELPs can be joined directly to genes that control the production of various proteins in cells, with the combination forming "fusion proteins." As the proteins degrade, they yield simple...

Researchers make nanosheets that mimic protein formation

...ials and devices, self-assembly offers substantial advantages over traditional manufacturing approaches, if we can design the building blocks appropriately. This is what we're trying to do." ...

Electric jolt triggers release of biomolecules, nanoparticles

...nt, the Searson team's approach could have several advantages over the container technology. "Because our molecules are attached to a surface, we can work with much smaller concentrations," Searson said. "We've also shown that our system is reusable. After a group of molecules is released, you can easily attach...

Stem cells found in adult hair follicles may provide alternative to embryonic stem cells

...llicles and have characteristics that combine some advantages of embryonic and adult stem cells, according to lead researcher, Maya Sieber-Blum, Ph.D., professor of cell biology, neurobiology & anatomy. Similar to embryonic stem cells, they have a high degree of plasticity, can be isolated at high levels of...
