University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts

...yester urethane scaffold using a rotational vacuum seeding device. After culturing their vascular constructs for seven days, the investigators then implanted them in the abdominal aortas of rats eight weeks before performing tests to determine how well the grafts had performed. The cell-seeded constructs...

Nano-devices hold promise for early-stage cancer detection

...id Elbestawi. "Funding support from government is seeding a nanotechnology cluster in Canada that can compete internationally."...

UNH researcher restoring oyster reefs to Great Bay

...shells on which young oysters settle and grow ?and seeding it with disease-resistant young oysters. Natural oyster reefs are formed by live oysters atop mounds of empty shells; one initiative of Grizzle's lab is soliciting "recycled" empty shells from oyster harvesters that will eventually be returned to the...

Findings advance use of adult stem cells for replacement bone

...search associate Upma Sharma, accomplished this by seeding discs of titanium mesh with stem cells and encouraging them to form extracellular matrix, or ECM, the boney, calcified deposit that gives bone its structural strength. A comparison was then run on these pre-generated ECM constructs and on non-treate...

'Punctuated' evolution in the human genome

...of the genome. "It is unclear why pericentromeric seeding events have occurred so frequently during this period of human/great-ape evolutionary history," says Eichler. "It is also unclear as to why they suddenly cease, at least in the case of this pericentromeric region of chromosome 2." Clearly, factors o...

New complete muscle grown in the lab

...ute of Technology, grew the muscle from scratch by seeding a sponge-like, three-dimensional plastic scaffold with myoblasts and endothelial cells, which are the precursors to mature skeletal muscle and blood vessel cells. The researchers also added connective tissue cells called fibroblasts to the mix as a c...

Distributed Basic Local Alignment Search Toolkit (W.ND-BLAST)

...fferent parts of the water distribution system and seeding formation of new biofilm colonies. When water enters a hospital room from a faucet or shower, tiny water droplets containing the biofilm contaminants separate from the main water stream and spread by air currents in all directions. Some of these con...

New strategies to reduce hospital-aquired infections

When water enters a hospital room from a faucet or shower, tiny water droplets containing the biofilm contaminants separate from the main water stream and spread by air currents in all directions. Some of these con...

The BIOS Initiative - open source biotechnology is born

... genes are and how they function. "These tools are seeding a growing movement ?the BIOS Initiative ?that will enable researchers, even in the poorest countries in the world, to be partners in the choice and development of the crop improvement technologies best suited to their own priorities", says Richard Je...
