Inflammation may cause preterm labor and fetal deaths

...the inflammatory response that is believed to have brought about the fetal death in mice. In a prior mouse study at Case Western Reserve, the investigators noted that inflammation closely paralleled localization of bacteria. In the present study, the researchers found that mice deficient in TLR4 lacked ...

...en) will examine the redistribution of vapor flows brought about by irrigation. Gordon notes that the pattern of change varies and identifies the mid-United States, the Amazon, the Sahel, India, and Northern China as the most likely areas to undergo climate change, driven by these altered continental vapor ...

...s provided two critical things, Rohrer noted. It's brought the science to the table and helped industry take advantage of the enzyme. It's also helped us to quantify the reduction of phosphorus to the environment. William Vanderwende, chairperson of the state's Nutrient Management Commission, said he has b...

Geisinger scientist seeks cure for Lou Gehrig's disease, creating device to find treatment

...nsive fish for finding new drugs have not yet been brought to market. The students have developed a working prototype screening plate that allows scientists to quickly expose zebrafish to ALS and mix chemicals together. What once took weeks or months to screen thousands of potential cure-carrying chemic...

Discoverer of Sly Syndrome finds way of delivering medicine to fight rare genetic disorder

... not. As the mice grew older, the transporter that brought the enzyme past the protective blood-brain barrier was lost. We found that the right amount of epinephrine allowed the enzyme to pass into the brain of older mice, which means we reinduced the way to get the enzyme where it is needed, Banks says. ...

Humboldt squid on the move

...seen for a year or two after a strong El Nio event brought warm water northward along the coast and into Monterey Bay. From 1999 until 2002, just a few Humboldt squid were seen during ROV dives. In 2002, however, large numbers of squid appeared after a mild El Nio event, and they have been abundant ever sinc...

Synthetic adhesive mimics sticking powers of gecko and mussel

... flexibility to adapt to rough surfaces. Next they brought in the mussel power, coating the pillars with a very thin layer of a synthetic polymer, designed by the researchers, that mimics the wet adhesive mussel proteins. The researchers measured the performance of the geckel material using an atomic force...

Serica scientists win AOSSM Award for ACL (knee) tissue regeneration in preclinical study

Study provides new data about the laws governing embryo development in organisms

...rtain interactions in the signalling pathways that brought to light a number of contradictions and showed that a key step was missing in their model. As Miln explains: Thanks to this computer simulation we have found a new genetic function that ensures the stability of the system and has enabled us to test i...

We have identified the missing molecule that normally keeps immune responses under control and appropriate. Having a food allergy...

MIT tool determines landslide risk in tropics
