A New Approach To Liver Transplantation In Rats Is Making Progress.
A unfledged come nigh to liver transplantation is making headway in beginning work with rats, researchers say. Their work at the Center for Engineering in Medicine at Massachusetts General Hospital (MGH-CEM) could at the end of the day point the way toward engineering fresh, functioning and transplantable liver organs out of discarded liver material, the researchers suggest. The research, reported online June 13 in Nature Medicine, is just at the "proof-of-concept" stage, but the crew believes it has successfully fashioned a laboratory process to liberate stripped down structural liver tissue and essentially "reseed" it with newly introduced liver cells.
The ovule cells are then coaxed to adhere to the host scaffolding, so that they flower and eventually re-establish the organ's complex vascular network. Although the highly complex competence is still far from the point at which it might be applicable to humans, the prospect is hopeful news for the liver transplant community. Because of a extreme shortage of donor organs, about 4000 Americans are deprived of potentially life-saving liver transplants each year.

Error Correction System Of The Human Brain Makes It Possible To Develop New Prostheses
Error Correction System Of The Human Brain Makes It Possible To Develop New Prostheses.
A further den provides discernment into the brain's ability to detect and correct errors, such as typos, even when someone is working on "autopilot". Researchers had three groups of 24 skilled typists use a computer keyboard. Without the typists' knowledge, the researchers either inserted typographical errors or removed them from the typed wording on the screen.
They discovered that the typists' brains realized they'd made typos even if the scan suggested otherwise and they didn't consciously be aware of the errors weren't theirs, even accepting task for them. "Your fingers notice that they add up to an error and they slow down, whether we corrected the error or not," said study lead architect Gordon D Logan, a professor of psychology at Vanderbilt University in Nashville, Tenn.
The dream of the study is to understand how the brain and body interact with the environment and break down the process of automatic behavior. "If I want to foment up my coffee cup, I have a goal in mind that leads me to look at it, leads my arm to sphere toward it and drink it. This involves a kind of feedback loop. We want to gaze at more complex actions than that".
In particular, Logan and colleagues wondered about complex things that we do on autopilot without much purposeful thought. "If I decide I want to go to the mailroom, my feet release me down the hall and up the steps. I don't have to think very much about doing it. But if you look at what my feet are doing, they're doing a complex series of actions every second".
