Indian-Australian scientist gives new hope to cancer sufferers

Sydney, August 07: An Australian scientist of Indian origin has developed a new method to send nanocells to cancerous tumours so that tumours that are resistant to other drugs can be destroyed.

Easily distracted? You could have low memory capacity

Washington, August 07: “That blasted siren. I can’t focus.” That reaction to an undesired distraction may signal a person’s low working-memory capacity, according to a new study.

Washington, August 07: Social stress could lead to heart disease by causing the body to deposit more fat in the abdominal cavity and could also speed up harmful plaque build-up in blood vessels, according to new research.

Gut hormone can lower sugar levels in diabetics

Toronto, August 07: Canadian researchers have found that a hormone in the human gut could be used to lower sugar levels in diabetics.

Researchers of the Toronto General Research Institute and the University of Toronto have found in their study on a rat model that activating receptors of the cholecystokinin (CCK) peptide hormone in the gut rapidly lowers blood glucose levels.

The activation of the receptors of this hormone triggers a signal to the brain and then to the liver to lower glucose or sugar production, say researchers in their paper.
