- Naked mole-rats bear chili pepper heat
01-28-2008 · EurekAlert!
Scientists have used gene therapy to restore sensation in naked mole-rats, strange rodents that lack a key neurotransmitter that causes prolonged pain perception in other mammals. The finding may lead to new analgesics for people with chronic pain who do not respond to current medication.

- Stressed-out African naked mole-rats may provide clues about human infertility
07-01-2007 · EurekAlert!
Naked mole-rats could shed light on stress-related infertility in humans, the 23rd annual meeting of the European Society of Human Reproduction and Embryology will hear.Dr Chris Faulkes, a senior lecturer at the School of Biological & Chemical Sciences, Queen Mary, University of London, will tell the conference that the African naked mole-rat is at the extreme end of a continuum of socially-induced reproductive suppression among mammals.

- Researchers develop targeted approach to pain management
10-03-2007 · EurekAlert!
Scientists have combined a normally inactive lidocaine derivative with capsaicin, the 'heat'-generating ingredient in chili peppers, to produce pain-specific local anesthesia. When injected into rats, this combination completely blocked pain without interfering with either motor function or sensitivity to non-painful stimuli.

- Fatty acid catabolism higher due to polyphenol intake
05-14-2007 · EurekAlert!
Polyphenols, dietary substances from vegetables, fruits and green tea, bring about a change in the energy metabolism. Dutch researcher Vincent de Boer has discovered that polyphenols increase the fatty acid breakdown in rats and influence the glucose use in fat cells.

10-08-2007 · EurekAlert!
Advanced genetics techniques reveal that the effects of cannabinoids on motor behavior and thermal and pain sensation are mediated by distinct populations of glutamatergic and dopaminergic neurons, not GABAergic neurons as previously thought.

- Anesthesia pouch allows children to go home sooner after surgery
11-02-2007 · EurekAlert!
Children recovering from orthopaedic surgery feel less pain and leave the hospital sooner when they go home with a small pouch that delivers local anesthetic agents and blocks pain transmission from surgical sites. Already used in adults, doctors at The Children's Hospital of Philadelphia adapted the technique for children.

- Naked Mole-Rat Unfazed By Oxidative Stress
10-10-2006 · ScienceDaily
The long-lived naked mole-rat shows much higher levels of oxidative stress and damage and less robust repair mechanisms than the short-lived mouse, findings that could change the oxidative stress theory of aging. The new study comparing the naked mole-rat, which has a life span of 28 years, and the mouse, which has a lifespan of three years, will be presented at The American Physiological Society conference, Comparative Physiology 2006: Integrating Diversity.
