Research Gives Hope For Liver Damage

...ophages causes scarring to the liver, but the next wave ofimmune cells, produced only a few days later, change function to breakdown and reabsorb the scarring. These findings, published in theJanuary edition of Journal of Clinical Investigation, will help doctorsto understand the mechanisms by which the l...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...d and fled to higher ground before the devastating wave struck, thus saving their own lives and those of the tourists riding on their backs. Because earthquakes and tsunamis generate low-frequency waves, O'Connell-Rodwell and other elephant experts have begun to explore the possibility that the Thai eleph...

Protein helps regulate the genes of embryonic stem cells

...research offers an important contribution to a new wave of thinking in genetics: that not all human disease states are due to alterations in DNA sequence. Dr. Terry Magnuson - Sarah Graham Kenan professor, chairman of genetics and director of the Carolina Center for Genome Sciences in UNC's School of Medi...

Nature provides inspiration for important new adhesive

...ke this protein so they can cling to rocks despite wave forces," Li said. "It's quite remarkable, just an incredibly unique natural feature." The mussel protein is a superior adhesive, but not readily available. In trying to identify a protein that could be adapted for this purpose, Li had another inspir...

Tamoxifen-like drug suggests new ways to selectively block estrogen

...uch as this should lead to the emergence of "a new wave of estrogen receptor modulators with improved specificity. We are moving, he said, "very close to the day where a proteomic profile of a tumor will determine the best SERM or SERD or other endocrine therapy that will yield maximal benefit in the clin...

Researchers reveal secrets of flying snakes

New law for resolution allows unprecedented sharpness in fluorescence microscopy

...ving cells non-invasively. However, because of the wave nature of light, focused light is subject to diffraction. As early as 1873, Ernst Abbe recognized that this fact imposes an absolute limit on resolution in microscopy. Abbe, whose 100th year death anniversary was in February, captured this limit in a...

Solution to 'legionella'

...pression of the gases dissolved in the water. This wave front produces a luminous plasma around the bubbles, as well as high pressure and temperatures. These pressures and temperatures have two effects: on the one hand, they eliminate the circulating bacteria and, on the other, they generate an oxidative...

New results validating Pall prion reduction filter disclosed at ISBT Congress

...can accurately determine the magnitude of the next wave of an outbreak. Nor do we know how many people may be harboring the infectious prions and also donating blood," Ross explained. "Our goal is to work with blood authorities across Europe and then North America to help them integrate this new measure o...

After three minutes of treatment at an intensity similar to what is used in physiotherapy ultrasound (about 2.5 watts), researchers observed that the tumors had little or no blood supply. "We used an ultrasound intensity hig...

Study finds 60 new genes controlled by DNA snippet

...be as important to medical science as genes. A new wave of research is concerned with, not how genes work, but how small regulatory DNA sequences tell genes where, when and to what degree to "turn on." As part of this effort, researchers at the University of Rochester Medical Center scanned through the va...
