Nerve cell memory holds key erasing pain

Nerve cell memory holds key erasing painToronto, Feb 14 : Researchers have found the key to how memories of pain are stored in the brain, especially in nerve cells (neurons), and how they can be erased to ease pain.

The central nervous system is known to "remember" painful experiences, that they leave a memory trace of pain.

And when there is new sensory input, the pain memory trace in the brain magnifies the feeling so that even a gentle touch can be excruciating.


Massaging promotes pain relief, muscle recovery

Massaging promotes pain relief, muscle recoveryToronto, Feb 6 - Most athletes would swear by the pain-relieving, muscle recovery-promoting benefits of massaging, which has now been validated by scientific evidence.

On the cellular level, massage reduces inflammation and promotes the growth of new mitochondria (cellular powerhouse) in skeletal muscle, says a new study.


Thinning of bones linked to heart failure

Thinning of bones linked to heart failureToronto, Feb 3 : Heart failure could also be linked to thinning of bones (osteoporosis), an offshoot of old age.

"Our study demonstrates for the first time that heart failure and thinning of bones go hand in hand," said Sumit Majumdar, University of Alberta in Edmonton, Canada, who led the study.
