Scientists pinpoint inflammation gene

...ralleled resource for genetic analysis, the center enabled an otherwise too-time-consuming comprehensive analysis to eliminate scientific "guesswork" on which variants ought to be investigated in the laboratory. The statistical analysis identified one particular variant in the SEPS1 gene a variation in the...

PET imaging reveals the immune system at work

...cer Center reports the results of experiments that enabled the group to tune in to the cellular battles waged by the immune system deep in the body. Using positron emission tomography or PET, Witte and his colleagues were able to observe key cells of the immune system as they responded to tumors in mice. "W...

Jefferson biologist coaxing human embryonic stem cells to make dopamine with simpler, faster method

Using positron emission tomography or PET, Witte and his colleagues were able to observe key cells of the immune system as they responded to tumors in mice. "W...

Recreating 'Flowers for Algernon' with a happy ending

...mp off as the log spun faster. But statin therapy enabled the NF1 mice to perform as well as their normal counterparts. "This is mind-blowing ?we think we have a real fundamental reason to be optimistic," explained Silva. "Here is a drug that affects a key learning and memory pathway, and completely resc...

Brainstem blocks pain to protect key behaviors

...ale rats in containers with a wire mesh floor that enabled them to deliver radiant heat to one hind paw. The heat caused no damage but was annoying enough to make the animal withdraw that paw within seconds. When the rats ate, however, they postponed retracting the heated paw for six to eight seconds an...

Scientists crack code for motor neuron wiring

...or neurons was an important technical advance that enabled the researchers to crack this code. Using these antibodies, Dasen and colleagues pinpointed the pattern of expression of each protein within the set of motor neurons that project to limb muscles. "Once we had these reagents, we were able to obtain th...

Texas scientists discover how a hepatitis C protein promotes liver cancer

... by hepatitis C viruses. "The replicon experiments enabled us to identify a protein known as NS5B that attaches to the retinoblastoma protein, a critical tumor suppressor, and accelerates its breakdown," Lemon said. He continued: "The way NS5B docks with the retinoblastoma protein is biochemically almost ide...

Infant transplant patients resist infections that kill adult AIDS patients

...onse to select viral immunization. This comparison enabled them to see that infant heart transplant patients had more help from the immune system post transplant -- even though some had a 10,000-fold reduction in T cells -- compared to the healthy control group. The nature of the compensating system is not y...

Stem cells from muscles can repair cartilage

...he authors state. They note that using fibrin glue enabled the cells to settle even in narrow clefts and has ... served as good carriers of a therapeutic gene and enabled the delivery of appropriate amounts of BMP-4 protein to the injury site," they state, adding that th...

3D ultrasound device poised to advance minimally invasive surgery

...ing the heart from outside the body. As technology enabled ever smaller ultrasound arrays, the researchers engineered probes that could fit inside catheters threaded through blood vessels to image the vasculature and heart from the inside out. The current advance relies on 500 tiny cables and sensors packed...

Carbon nanotube absorption measured in worms, cancer cells

...te---with the carbon-14 radioactive isotope, which enabled the nanotubes to be tracked and quantified as they were absorbed into living cells. Researchers used cancer cells called HeLa cells, and also measured nanotube uptake in an earthworm and an aquatic type of worm. The findings were presented Sunday a...

'Banana-jawed' fossil mammal linked to rare sound-producing skill

...nosaur sound-producing skeletal cavities that have enabled scientists to reconstruct the possible sounds made by them. Now, DeBlieux would like to do the same for the fossil hyrax. "It would be really neat," he said, "to model their jaws so we could hear the sound these curious creatures actually made." ...

Researchers reverse juvenile diabetes in animal model

...the beta cells in the pancreas to regenerate. This enabled the pancreas of the mice to begin producing insulin again," said Dr. Trucco, who also is the Hillman Professor of Pediatric Immunology at Children's Hospital and a professor of Pediatrics at the University of Pittsburgh School of Medicine. "The injec...

Natural selection at single gene demonstrated

...rsions of FRI that appeared thousands of years ago enabled the plant to flower year-round, helping it out-compete other plants. Toomajian and his group showed that these two versions, also called gene variants, are too common to have spread solely by chance. "We've shown that for one gene with an important...

Warbling whales speak a language all their own

Cheaper and simpler keyhole surgery

...hout a (camera) assistant. A test showed that this enabled 'solo surgery' and that it even brought advantages in comparison to surgery using an assistant. The second instrument developed by Jaspers is a mechanical manipulator for operating the various instruments used in keyhole surgery. Two mechanical arms...

How 'hot' emotional brain interferes with 'cool' processing

...ing link in our earlier studies," said Dolcos. "It enabled us to determine whether there was, indeed, a behavioral connection between deactivation of the dorsal system and impaired performance. "The experimental design mimicked the kind of distraction people experience in everyday life," Dolcos added. "For...

Alternatives to the use of nitrate as a fertiliser

... University of Navarre in this field and which has enabled new data to be obtained about the response mechanisms of various plant species arising from the stress produced as a result of the use of exclusively ammoniacal fertilisers. Stress in this sense is understood as the processes that produce a decrease ...

Cracking the genetic code for control of gene expression

...mice. Novel experimental and computational methods enabled genome-wide analysis of regulatory elements in several species. Studying the control of gene expression is a growing area of research at the moment, likely owing to its fundamental importance to many biological processes. The findings of the Finnis...
