Marburg, Germany (dpa) - Dangerous moles and birthmarks can be recognized using five criteria, according to a German health and consumer organization based in Marburg.

People can determine whether they need to consult a doctor about a possible case of skin cancer by using five criteria to evaluate their own moles and birthmarks. They are summed up as the ABCDE rules - A for asymmetry, B for border, C for colour, D for diameter and E for embossment.

Washington, Apr 22: A University of Leicester researcher has made some significant advancements on the causes of cancer, which can lead to improved and effective therapies.

Professor Andrew Fry, of the Department of Biochemistry aims to understand the molecular control of cell division and as a result identify proteins, which can be targeted in specific tumours, leaving other cells unharmed.

Many current cancer treatments act by killing all dividing cells and are not necessarily specific for the cancer cells, hence the severe side effects.

Ludhiana, April 22: With a rising concern for health across the world, a lot of people in Punjab are increasingly getting drawn to alternate systems of medicine to escape the side effects of modern-day drugs.

A two-day awareness meet was held here recently to educate people on the traditional systems of medicine in India. `Arogya’ – meaning `holistic health’ was the ninth such event organised in the country aimed at promoting healthy living in modern-day society.

London, Apr 22: While proteins are known to be at the centre of every life process, and carry out all sorts of work by going to the cell, what guides these basic molecules towards their target cells in the brain has been unknown, until now.

Don Arnold- a molecular and computational biologist at USC College-and colleagues have now solved the mystery for key proteins in the brain.

"There''s no little man sitting there, putting the protein in the right place. Proteins have to have in them encoded information that tells them where to go in the cell," Nature quoted Arnold as saying.

Washington, Apr 22: A new study has claimed that there’s a need for doctors to know about medical tattoos—an increasingly popular trend to let others know about one’s medical condition.

One of the most obvious benefits of medical tattooing is for identification purposes in an emergency situation.

And it is especially useful for patients with diabetes, when a patient may be incapacitated—particularly in the case of hypoglycemic coma.

London, April 22 : A team of British scientists has found that nicotine chewing gum, lozenges and inhalers designed to help people to give up smoking may have the potential to cause cancer.

The research team, led by Muy-Teck Teh, of Queen Mary, University of London, has found a link between mouth cancer and exposure to nicotine, which may indicate that using oral nicotine replacement therapies for long periods could contribute to a raised risk of the disease.
