Embryonic stem cells correct congenital heart defect in mouse embryos
...cells to influence neighboring defective cells and restore their capacity to function normally. Researchers at Memorial Sloan-Kettering Cancer Center report that 15 embryonic stem cells injected into early embryos of mice whose hearts were genetically predisposed to develop a lethal defect, rescued the heart...Researchers find protein that makes long-term memory possible
...ilarly, the scientists also found that mBDNF could restore L-LTP in brain slices from mice incapable of producing plasminogen. Next, the researchers treated plasminogen-deficient brain slices with a form of proBDNF that could not be converted to mBDNF. Again, L-LTP could not be induced in these hip...Delay in cutting the cord helps premature babies
...to the baby's body. "A little extra blood can help restore blood pressure," says Raju. Low blood pressure may require transfusions of blood or fluids, which can be tricky to accomplish safely in a preterm baby. On the other hand, delaying clamping too long can actually pack too many red blood cells into the...UCLA scientists discover new way to fix defective gene

"Saline, the current standard of care, helps us restore a patient's blood pressure but does not deliver oxygen, a critical nutrient to prevent organ damage in the brain, heart, lungs, liver and kidneys," Gamelli explained.
