Clue found to Epstein-Barr virus' ability to form and sustain tumors

...n. "If we can identify this protein, it will be easier for us to develop assays to screen for small molecules that will compete with the protein in binding to EBNA-1," Sugden says. "By preventing the cellular protein from binding with the segment, EBNA-1 will not be able to carry out its function and the...

Preliminary study finds holographic imaging system promising for cancer treatment planning

... and size of over or under-dosed regions were also easier to identify on Perspecta. The reviewers reported that Perspecta produced a better plan in six out of 12 brain cases and was better in the one lung cancer case and one breast cancer case studied. "Our study found the Perspecta Spatial 3D Display ...

New fMRI technology making brain tumor surgery safer

...eurosurgeon with The Neuroscience Institute: “It’s easier and safer for the patient, and it can reduce the length of surgery.? The fMRI technology is manufactured by BrainLAB and marketed as iPlan BOLD (blood oxygen level dependent) MRI Mapping. It has been used successfully in 12 surgical cases so far at...

Dig deeper to find Martian life

...les. Ice also holds an advantage because it is far easier to drill through than rock. Even here, surviving cells would be out of the reach of current drills. Other ideal sites include recent craters, because the surface has been exposed to less radiation, and the gullies recently discovered in the sides of ...

Cholera pathogen reveals how bacteria generate energy to live

...perimental study, according to Barquera. Sodium is easier to trace and its concentration can be changed without affecting pH, which is a complication with protons. "It’s a very good system to understand this very basic mechanism charging this battery to create energy," she said. In order to learn how the...

Nanoparticles for delivery of prostate cancer treatment

...hey do not reproduce, are not immunogenic, and are easier to produce than adenoviral vectors," said Garen. The nanoparticles will have a tag on their outside that binds to the tumor blood vessels. After binding, they are taken up by the cells and unload the gene that codes for the Icon, allowing the cells t...

Bacterial response to oxidation studied as toxin barometer

...to calibrate a sensor,?she said. “The bacteria are easier to prepare and more robust than using mammalian cells, such as rat brain tissue. Brain tissue is the most sensitive to toxins. We wanted to relate the bacteria response to cell response, like a barometer.? “And we saw that it corresponds well,?said...

Anti-dandruff compound may help fight epilepsy

...s surface,?Li says, “then ZnPy made this door both easier to open and stay open longer. It’s like a tunable ...emicals that stop things from working - it’s a lot easier to close or block a door than open it,?Li says. “But here we found a chemical that makes a defective...

Common mechanisms for viral DNA replication

...uble-membrane nucleus. However, the process is far easier to study in the much simpler virus. In simian virus 40 (SV40), the large T-antigen protein (T-ag) is responsible for recognizing DNA sequences required to start replication, called the origin of replication. SV40 T-ag can also cause DNA to melt or un...

DNA layer reduces risk of reserve parts being rejected

...ne responses. Van den Beucken's invention makes it easier and more reliable to use implants and has already been patented. Van den Beucken reasoned that a DNA coating should have a lot of advantages. Such a coating approximates the body's own material with the result that a less intense immune response oc...

Liposuctioned fat stem cells to repair bodies

... the focus is shifting to fat, since the tissue is easier to access and extract than the bone marrow. That fat-based methods work is not surprising, perhaps, because adipose tissue is closely related to bone, cartilage, muscle and other connective tissue. But some say it is impossible to re-programme adult ...

Anti-herpes treatment reduces HIV levels in women infected with both viruses

... the levels of HIV in the genital tract3, allowing easier transmissibility of the virus. In addition, the HIV viral load in the blood of HIV-1 infected patients increases, at least temporarily, during episodes of HSV reactivation. Lead author Dr. Nicolas Nagot, of the London School of Hygiene & Tropic...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...Added Arzberger: "Fighting a pandemic will also be easier if we put in place the infrastructure to replicate data, support medical informatics, and even assist in remote diagnosis." UC San Diego will lead the one-year project, with more than $350,000 in funding from the Telemedicine and Advanced Technol...

Natural polyester makes new sutures stronger, safer

...an sutures now used and very flexible, making them easier for surgeons to work with. The sutures were developed by Tepha, Inc., a Cambridge company that hopes to use the same material to produce an array of absorbable medical devices, including stents, surgical meshes and possibly a heart valve scaffold,...

Scientists unlock mystery of embryonic stem cell signaling pathway

...any risk of contamination, it would make life much easier for scientists than it is at the moment,?says Kahn. “And that’s our goal.?"Kahn's study provides us with striking new insights into the molecular regulatory machinery inside embryonic stem cells,?adds Martin Pera, Ph.D., director of the Center for St...

Small molecule dervived from Rb2/p130 could act as cancer therapeutic

...therapy. For these reasons, he believes it may be easier to get approval for clinical trials. "Fifteen years after discovering Rb2/p130, our research and hard work has led us to the discovery of this small molecule, which is a step forward in cancer research and a big step toward a cancer treatment," he...

Stopping plants from getting sick

... fact, genomics and computers have made this a lot easier during the last five to 10 years. Before it would take a graduate student all of his or her research time to sequence and characterize one gene. Now that we have sequenced the genome of a smut fungus, I can look through thousands of genes on my deskt...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

... Technology and Emory University have developed an easier and faster method to detect these types of target molecules in liquid samples using highly porous, micron-sized, silica beads. The researchers developed a technique to simultaneously or sequentially add optical and magnetic nanoparticles into the ...

Large size crucial for Amazon forest reserves

..."With a handle on the detection problem it is much easier to understand real species occurrence", said Nichols, "and looking at occurrence through time, one understands the dynamics of species faced by forest destruction". Some vanish because they don't survive in a given site, others because they don't co...

Surgeons develop simpler way to cure atrial fibrillation

...is technology has made the Cox-maze procedure much easier and quicker to perform," says Ralph Damiano Jr., M.D., the John Shoenberg Professor of Surgery and chief of cardiac surgery at the School of Medicine and a cardiac surgeon at Barnes-Jewish Hospital. "Instead of reserving the Cox-maze procedure for a ...
