Drugs disrupt formation of blood vessels

...entists tested drugs to see if they could stop the signals that are emitted to trigger the formation of the blood vessels that fuel the growth of tumours. Four compounds, known as AGM-1470, BB-94, angiostatin and endostatin, together with a combination of the last two, were tested. They found that if admin...

Drug abuse leads to long standing changes in the brain

...ls that are part of a brain circuit that transmits signals using the chemical dopamine, which plays a role in movement control and feelings of pleasure. The researchers administered a battery of tests to assess attention, memory, mood, general intelligence and motor function. Results showed that, on averag...

New treatment for depression

... implanted in a person's chest, sends intermittent signals to the left vagus nerve in the brain. The device was originally used to treat patients with epilepsy. However, it was later found to have a positive effect on the part of the brain that regulates mood prompting these latest trials. Doctors at the u...

...omes desensitised to that smell. By measuring the signals from these odour receptors cells in genitically engineered mice, one research team showed that mice lacking CNGA4 could sense odours but could not adapt to them.Other scientists studied the molecule’s behaviour in laboratory-grown cells and reported ...

Epilepsy can be predicted

...tale transition phase in the pattern of electrical signals emitted by the brain prior to a seizure that lasts for several minutes. In 25 of 26 recordings, picking up these changes allowed the researchers to anticipate a seizure on average seven minutes before it occurred. They say: "The ability to anticipa...

Leptin connected to obesity blood clots

...n has been seen as a hormone that produces satiety signals in the brain and stops people wanting to eat once they're full. Mice without leptin grow massively fat, but it's been hard to reproduce this finding in humans - so leptin is not about to become a wonder slimming pill. However, other research in hum...

Leptin linked to Blood Clots

...l Association. Leptin is released by fat cells and signals the body to stop eating. But this system can break down in overweight people, Eitzman explained. Leptin levels can get too high among obese individuals and when that happens, the person can become resistant to leptin's signals, making them more vulne...

Gestational Diabetes linked to Chromosomal defici

...am points out, for some women gestational diabetes signals an increased risk of developing type 2 diabetes. For others, it may be precursor to type 1 diabetes, a form of the disease caused by an abnormal immune system attack on the body's insulin-producing cells. The researchers speculate that some women wit...

Morphine may excite cancerous tumors

... to cancer patients to manage severe pain, provoke signals in endothelial cells, or cells that form blood vessels, and activate mitogen-activated protein kinase (MAPK). MAPK promotes endothelial cell multiplication and angiogenesis, or formation of new blood vessels. Angiogenesis can cause tumor growth by pr...

Modified antibiotic may support fight cancer

... COL-3 appears to block some of the chemical signals that come from an existing tumour that otherwise encourage cancer cells' movement throughout the surrounding tissue. It may be that COL-3 would be useful in conjunction with conventional anti-cancer drugs which kill cancer cells. Further research wil...

Want to have a nice day? Eat breakfast!

The brain is forced to depend on stored fat for functioning when glucose supply runs low as a result of skipping breakfast. Many peo...

Vision loss could result due to MSG

The findings were published following a study which involved rats that were fed with diets high in MSG over a six month period in Japan. The results indicated that these rats developed thinner retinas after being fed with a hig...

Stroke victims have new hope with activated protein C

Researchers concluded that the compound which is working in a completely unexpected way could spur further research to help develop treatments that reduce the lifelong disability often associated with stroke....
