Human stem cell treatment restores motor function in paralyzed rats

...used in the study. “In this study, we succeeded at reconstructing the neural circuitry, which had not been done before.” The researchers believe that the therapy may eventually be proven even more effective in human patients, who would be able to receive physical therapy once treated. “Physical therapy may a...

Are scientists making progress in being able to regenerate bone tissue?

...ls has been suggested as a promising technique for reconstructing bone defects,?say Meijer and colleagues. Bone tissue engineering has shown success in animal studies. In their article the authors review the available data on bone tissue engineering in human studies, including clinical research they themselves ...

Scientists reverse evolution

...hown how evolution works by reversing the process, reconstructing a 530-million-year-old gene by combining key porti...process of evolution by reversing this process and reconstructing a gene that later became two genes," he adds. The study by Capecchi and postdoctoral fellow Petr ...

Even a little cooling helps after cardiac arrest

... in resident snails thus becomes a clever means of reconstructing the food web in the area, as the trematodes reflect the predator-prey relationships that must be occurring to support their reproductive lifecycle. "Trematodes require all of the pieces of the puzzle to complete their lifecycle," Lafferty said. "Whe...

How healthy is that marsh? Biologists count parasites

... in resident snails thus becomes a clever means of reconstructing the food web in the area, as the trematodes reflect the predator-prey relationships that must be occurring to support their reproductive lifecycle. "Trematodes require all of the pieces of the puzzle to complete their lifecycle," Lafferty said. "Whe...

Plastic surgeons countdown first full facial transplantation

...d flaps, are reliable and effective techniques for reconstructing the face, they may not be ideal, according to the studies. It is nearly impossible to match the skin quality, texture and color of the face with any other tissue available on the body. In addition, it takes multiple grafts and surgeries to successfu...

UCSD biologists find new evidence for one-way evolution

.... The authors suggest that traditional methods for reconstructing the history of trait evolution may be inaccurate. ...considering genetic data underlying the trait when reconstructing its evolutionary history. "Our work implies that evidence for such evolutionary change in other ca...

Next good dinosaur news likely to come from small packages

...ned from examining organic matter in meteorites to reconstructing who eats who in the food web from the tropics to the arctic. The trail is laid by stubbornly durable molecules. She uses mass spectrometry, an analytical technique that determines what molecules are present. Molecules may be tiny, but they can be to...

Technique makes it easier to see mouse embryo in all its glory

...viewing slides under the microscope, then mentally reconstructing the three-dimensional aspects of the embryo to reveal pertinent biological information. Under the new method, the intact embryo is stained to distinguish tissues (organs, developing bone and soft tissue) and is digitally scanned at high resolution us...

Missing fossil link 'Dallasaurus' found

...puter simulation. When funds become available for reconstructing a suitable exhibit, the bones of Dallasaurus will be displayed at the Dallas Museum of Natural History. The work, however, will take several more years of additional efforts and substantial funding. A nearly 30-foot long mosasaur, some 75 million yea...

New possibilities for flu antiviral and vaccine research emerge from 'Spanish flu' virus

...any of them otherwise healthy adults. By partially reconstructing the Spanish flu virus, researchers have now discovered at least part of what made the virus so lethal, thus providing essential information for influenza drug and vaccine research. The research appears in the 7 October issue of the journal Science,...

Scientists focus on 'dwarf eye'

...the Wilmer Eye Institute in 1998 for treatment. By reconstructing the woman's family tree, the researchers discovered that several living relatives also suffered from nanophthalmos, and four deceased relatives had been part of the classic Johns Hopkins Bloomberg School of Public Health study in the 1970s that helpe...

Scientists use manufacturing methods to reconstruct mastodon

... of Michigan Exhibit Museum of Natural history are reconstructing a male mastodon skeleton for an exhibit that opens to the public May 21. Meanwhile, museum visitors can peek through special viewing windows to watch preparators assemble the skeleton, which will bear 7-foot tusks. The specimen, named the Buesching ...

Circles Of DNA Might Help Predict Success Of Stem Cell Transplantation

... likely either to fail or be significantly slow in reconstructing the T cell population. "This is the first demonstration that high levels of sjTREC in a potential stem cell recipient can predict that their thymus will successfully reconstitute their T cell population using donated stem cells," said Xiaohua Chen, ...

Dinosaur DNA? New Patent Covers Degraded DNA recovery

...by our scientists, brings us closer to our goal of reconstructing genetic history. We now have the picture on the outside of the puzzle box, and by stringing together the pieces of aged DNA, we should be able to reconstruct genes from animals such as the wooly mammoth, giant sloth, saber-toothed cat or even from ti...
