Rice bioengineers pioneer techniques for knee repair

... his students Adam Aufderheide and Gwen Hoben have perfected methods of growing meniscus-shaped pieces of cartilage, but they are still trying to perfect the mechanical strength of the engineered meniscus tissue, which must be able to withstand up to an astounding 2,400 pounds per square inch of compressive pr...

Lack of a key enzyme dramatically increases resistance to sepsis

... "Without the experimental model of peritonitis perfected by John Mathison from Scripps Research, we would not have been able to differentiate between the two mouse phenotypes," Ulevitch said.

This midline -- think of the dorsal, tail and anal ...

Spinal cord bridge bypasses injury to restore mobility

...ional connections. Silver said if the method is perfected and successful with primates, it could go to human trials within a relatively short time. His next step is a neural bridge that would help quadriplegics, who are unable to breathe without assistance, move their diaphragms on their own. In futur...

Engineering the heart piece by piece

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex

...e rid of contaminants. Using techniques and tricks perfected while working on the mammoth sample, Asara purified the protein, identified as collagen, and, with the enzyme trypsin, broke it down into fragments, or peptides, 10 to 20 amino acids long. The peptides were passed over a liquid chromatography (LC) co...
