Longer treatment benefits sleep apnea patients

... works by blowing just enough air into the nose to keep the patient's throat open. Because they often find the CPAP device cumbersome, many patients do not use it consistently or for long enough periods while sleeping.

The basic hypothesis of the project was that the organ of balance -- which helps stabilize an animal's gaze and coordinate its movements as it travels through the environment -- should be irrevocably linked to the type o...

Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state

To keep the palladium(II) from going to a neighboring electrode a second reagent was added to the solution above the chip that destroyed the palladium(II) reagent. In this way, nothing happened at electrodes that were not being used. Reversing the polarit...

'Insulator' helps silence genes in dormant herpes virus

...tists have long puzzled over the mechanism used to keep this small region of the genome going while nearby genes remain quiescent. Now, scientists at The Wistar Institute have discovered a molecular mechanism that keeps HSV-1 activation restricted to a single gene for months or even years. The research...
