How roots control plant shoots
...rought, "an unknown signal comes from the root and restricts leaf growth," Sieburth says. Plants with mutant bps1 in the study also allowed the faucet to be wide open. That is why when roots were cut off repeatedly, the flow of growth-inhibiting hormone stopped and leaves grew normally. Van Norman believes...Protein protecting brain from toxins also blocks some chemotherapy from reaching tumors
...tecan and transporting it away from the brain Mrp4 restricts the drug's penetration into the brain from the bloodstream; and it protects brain cells from accumulating toxic levels of topotecan molecules that do escape the bloodstream.

In the United States, animal work is allowed but work on human embryonic stem cells is restricted to cell lines in existence prior to Aug. 9, 2001.

We have found that the stiffer a horse's leg restricts how quickly it can transmit force to the ground and bounce back up again and also increases the chances of injury. The team has also found that fast horses can bring their legs forward quickly in preparation for the next stride but that this is more ...Genetic variant linked to weakened heart pumping
