New cell transplantation technique restores insulin production in diabetics

...The sandwich technique is so-called because of the layered applications of gelfoam and coil used to close the access site." Dr. Krishnamoorthy said that even though percutaneous islet cell transplantation is currently an experimental procedure, the sandwich closure is a safe method that prevents many of the...

Sea urchin genome suprisingly similar to man and may hold key to cures

...regulate just one gene expression of a single-cell layered gut of the sea urchin larva, at least 14 proteins binding the DNA at 50 sites are needed, Calestani said. "Multiply that hundreds of times and you begin to understand the level of complexity involved in human development," she added. Using a "s...

A new approach to growing heart muscle

...ormed in just four days after a million cells were layered on fibrin gel could contract with an active force of more than 800 micro-Newtons. That's still only about half the force generated within the tissue of an actual beating heart, but it's much higher than the forces created by engineered heart tissue s...

Dig deeper to find Martian life

...tested; dry regolith, water ice, and regolith with layered permafrost. The particle energies and radiation doses were measured on the surface of Mars and at regular depths underground, allowing the calculation of cell survival times. The team took the known radiation resistance of terrestrial cells combin...

Volcanic eruptions, ancient global warming linked

...d the Faeroe Islands, where they cooled, leaving a layered sequence of lava flows as deep as six kilometers in some places. Duncan said the eruptions are similar in scale with the well-known Deccan Flood Basalts in India. "They are also about 40 times as big as the Columbia River basalts in Oregon and Was...
