Bioartificial kidney under study at MCG

...transplant. The cells are grown into the walls of thousands of hollow fibers contained in a cartridge similar to those used for traditional dialysis. With dialysis, a patient's blood runs through the fibers and a solution with the normal composition of electrolytes runs on the outside. Through osmosis, waste...

Man and mouse share genome structures

...HOX regions, we see huge stretches of genome, many thousands of base pairs in length, that are completely covered by tags." The researchers speculate that these unique chromatin structures could be activating sets of HOX genes for specific developmental programs. This global activation may have implications f...

UCSB scientists probe sea floor venting to gain understanding of early life on Earth

...may therefore repeat episodically over hundreds of thousands of years as abyssal hills are uplifted and spread away from the mid-ocean ridge crest. Haymon compared the subsurface microbes they found to those living in hot springs such as those at Yellowstone National Park. ...

New, automated tool successfully classifies and relates proteins in unprecedented way

...g of proteins inside cellimages, we also can study thousands of images fast, objectively andwithout error," Murphy said.Murphy's tool has two key components. One is a set of subcellularlocation features (SLFs) that describe a protein's location in a cellimage. SLFs measure both simple and complex aspects of pr...

Ecological destruction fuels emerging diseases

...r to non-existent understanding of the roles these thousands of parasites play in different diseases, something that will require a detailed understanding of their often complex multi-host life cycles. "It's very difficult to link these things up," he says. "It's very time consuming to do that, but without th...

New Technique for Tracking Gene Regulators

...genome:three billion nucleotides, and many tens of thousands genes. Trying toascertain which of these genes CREB regulates by more traditionalmethods, evaluating one gene at a time, would be too labor-intensive,expensive, and take a very long time.Scientists have been working on short cuts, but all so far have...

HIV Patients May Be at Risk of Heart Problems When Taking Protease Inhibitor Drugs

...'ve found, and act accordingly. Worldwide, tens of thousands of people are taking protease inhibitors, and the numbers who experience these unexpected side effects are very low -- much less than 1 percent." Co-investigator Michael Ackerman, M.D., Ph.D. agrees that the benefits of the drugs far outweigh the ri...

Study finds more than one-third of human genome regulated by RNA

... that smallRNA molecules called microRNAs regulate thousands of human genes--morethan one third of the genome's protein-coding regions. In other words,a class of molecule once relegated to the sidelines may be one of theprincipal players in regulating cellular mechanisms. "It's exciting to see how many genes ...

Gene therapy converts dead bone graft to new, living tissue

...as living bone, is a promising development for the thousands of cancer and trauma patients each year who suffer with fragile and failing bone grafts. The findings were posted online Feb. 13 and will appear in the March 1 issue of Nature Medicine. The procedure, designed by a team led by Edward M. Schwarz, Ph....

Researchers reveal the infectious impact of salmon farms on wild salmon

...l sampling techniques that allowed them to examine thousands of the fish for parasites, taking measurements every 2 to 4 km. The fish start in the rivers and head to sea, traveling en masse in large mixed schools. Thus the scientists could see the effect on the salmon as they moved toward the farm. They found ...

Color-blind method opens new doors in DNA sequencing

...) steps, reduce its length to a manageable size of thousands of nucleotides. Using natural replicating enzymes, the DNA is tagged with four fluorescent dyes, each corresponding to a particular nucleotide. This tagging process, called Sanger sequencing, results in smaller DNA fragments, which are then separated...

New Clues Add 40,000 Years to Age of Human Species

In addition, the sediments show that each major layer deposited very rapidly, perhaps within a few thousand years or less...
