Bioartificial kidney under study at MCG

...g as the patient is in failure. Kidneys require a lot of oxygen and energy to perform their endless task, which makes them easy targets in the ICU, Dr. Szerlip explains. As examples, kidneys can become ischemic and begin to fail if blood pressure drops because of a long surgery with significant blood lo...

Yellowstone microbes fueled by hydrogen, according to U. of Colorado study

...n this analysis, I think hydrogen probablydrives a lot of life in a lot of environments," Spear said. "It's partspeculation, but given the number and kinds of bacteria that...

“Nano-scissors?laser shows precise surgical capability

... in thelaser concentrate in one area, delivering a lot of power to a tiny,specific volume without damaging surrounding tissue.?Once cut, the axons vaporized, and no other tissue was harmed.To assure the axons were actually cut, and their disappearance wasn’tcaused by discoloration by the laser, the resea...

Gene variations explain drug dose required to control seizures

...tients, Goldstein said. "For most drugs we know a lot about how and where they act in the body," Goldstein said. "The current results support the idea that known drug targets, transporters and drug metabolizing enzymes are good starting points for understanding variation among patients in drug response....

Solution to Pollution: New Bacteria Eats Toxic Waste

...ycobacterium. “Putting together genomes tells us a lot about the history of the world and may even help us with its future,?said Joanne Hughes, a Utah State Biology professor. The Department of Energy will sequence the genetic material of the microbes, and the researchers will then participate in the an...

Experiments provide proof of how traveling in groups protects insects

First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...has become an alternative strategy that's gained a lot of interest among researchers." If compounds could be found that slowed or halted cancer spread, doctors could gain valuable time in shrinking the primary tumor. "If we had the luxury of time, we could treat that primary tumor at lower doses, too, w...

The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures

... of new materials, such as reagents. “There are a lot of proteins that are incredibly important to understanding human biology and medicine, yet we know very little about most of them,?said Norvell. “The PSI will provide important information about these molecules so vital to life.?/p> The nine pilo...

Breast Cancer May Be 'Uniquely Sensitive' To Inhibitors Of PI3K Pathway

Falling ants glide back to trunk to avoid dangers of forest floor

... and bees. "Apparently, it's fairly common among a lot of tropical canopy ants." Yanoviak, Dudley, a professor of integrative biology at UC Berkeley, and zoologist Michael E. Kaspari, an ant ecologist at the University of Oklahoma, Norman, report the discovery in the Feb. 10 issue of Nature. After Yano...

Family trees of ancient bacteria reveal evolutionary moves

...ions that triggered change, but I'm arguing that a lot of these things could be evolutionary." Blank presented her research at the 2004 annual meeting of the Geological Society of America, held, Nov. 7-10 in Denver. Blank's finding that Cyanobacteria emerged first in fresh water lakes or streams is coun...

Artifical cornea lets woman blind 20 years see

...lved with the keratoprosthesis. Patients require a lot of follow up to make certain the artificial cornea remains structurally sound and healthy." Because the artificial cornea is a foreign body, it doesn't "heal" the way a wound would and become a part of the body. There could be complications over tim...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

...was fighting the kinesin, we would expect to see a lot of smaller steps as well." The researchers also noted that faster movements occurred with the same step size, but with greater rapidity. When measured outside the cell, kinesin moved about 0.5 microns per second. Inside the cell, the speed increased...

Fleshing out the genome

...etoxifying bacterium Shewanella oneidensis. "In a lot of cases," said James K. Fredrickson, a co-author and PNNL chief scientist, "it was not known from the gene sequence if a protein was even expressed. Now that we have high confidence that many of these hypothetical genes are expressing proteins, we c...

Polymers with copper show promise for implanted sensors

Alaskan puzzles, monitoring provide insight about North Pacific salmon runs

...uatic and fishery sciences. "The Kvichak sounds a lot like Columbia River or Puget Sound stocks," he says. Still, 20 miles away from the Kvichak are similar lakes and rivers with record production. "Our research is directed toward understanding why these runs see such different trends, by looking broa...
