Glimmer of hope for Tahitian tree snails' survival
07-02-2007 · EurekAlert!Despite the mass extermination of Tahiti's unique species of tree snails in recent decades, much of their original genetic diversity can still be found in remnant populations that survive on the island, researchers report in the July 3 issue of Current Biology, a Cell Press publication.

- Report calls for using heated chemotherapy after colon cancer surgery to optimize patient survival
11-03-2006 · EurekAlert!
There is new hope for some of the most seriously ill colon cancer patients today, following the release of a consensus statement by 72 leading oncology surgeons from 14 countries, including the United States. The Peritoneal Surface Malignancy Group (PSMG) has concluded that surgery, followed by heated chemotherapy delivered through the lower abdomen of the patient before leaving the operating room, may significantly increase the life expectancy for patients with Stage IV colorectal cancer.

- The beetle's dilemma
06-25-2007 · EurekAlert!
Large-headed beetles can readily crush snail shells with their powerful jaws, but cannot insert their oversized heads into the shells. Small-headed beetles can insert their heads into the shells for direct predation on snail bodies, but poorly crush the shells because of their small jaws. The same trade-off shapes the snails. Elongate shells protect against entry attacks and rounded shells protect against crushing attacks.

- Chemical compound found in tree bark stimulates growth, survival of brain cells
10-01-2007 · EurekAlert!
Researchers have identified a compound in tree bark that mimics the chemical reactions of a naturally occurring molecule in the brain responsible for stimulating neuronal cell signaling. The tree bark compound, known as gambogic amide, behaves much like Nerve Growth Factor, a molecule found in the brain. NGF binds to TrkA, a neuronal receptor, and activates neuronal signaling. It is known that the loss of TrkA density correlates with neuronal atrophy and severe cognitive impairment such as that associated with Alzheimer's disease.

- Scientists a step closer to understanding how anaesthetics work in the brain
07-19-2007 · EurekAlert!
An important clue to how anaesthetics work on the human body has been provided by the discovery of a molecular feature common to both the human brain and the great pond snail nervous system, scientists say today. Researchers hope that the discovery of what makes a particular protein in the brain sensitive to anaesthetics could lead to the development of new anaesthetics with fewer side effects.
