India sets target of building 5.2 million toilets by end of August

My article in British Medical Journal, where the director of the Nirmal Bharat Abhiyan said the 5.2 million target was an enhanced one, because they had added an buffer for any shortfall.

To prescribe or not to prescribe

India's drug regulator, the Central Drug Standards Control Organization, operates with a skeletal staff and laxer regulations than the American Food and Drug Administration. This could explain why so many Indian generics makers are facing restrictions on exporting to the USA, but continue to manufacture drugs with no bar in India. 

This does not necessarily mean all Indian drugs are unsafe. What it does mean is that the risk of adulteration and poor quality is higher, but will often go undetected.

Can obesity be healthy? And can we tell when it's harmful?

A new study published in Cell Journal has identified an enzyme called heme-oxygenase-1 (it degrades heme, a component of hemoglobin in the body), which may be a significant cause of obesity-related metabolic disease.

All of us know people who are obese, and yet healthy. They may be small in number, but they have none of the signs of metabolic disease (high blood sugar, cholesterol or BP) which affect overweight people so often.

What protects this people? Is there some factor, in addition to obesity, that leads to metabolic disease. The authors of the Cell Study believe this factor could be HO-1.

To know more, read my article in Science Magazine.

Car exhaust keeps moths from smelling the roses

A study in the journal Science found that the smell of car exhaust and other urban emissions makes it harder for moths to find flowers. It turns out that moths are not really confusing one for the other. Instead, one smell is altering the representation of the other smell in the moth's brain. Why does this happen? What is common between fuel emissions and flower fragrances? The answer is that several of the volatile organic compounds (VOCs) in fuel emissions are derivatives of benzene, as are VOCs in the smell of flowers. For example, benzaldehyde, a compound in the plume of the Sacred Datura flower, is formed by substituting a formyl group compound for a hydrogen atom in a benzene ring. Toluene, found in fuel fumes, comes from substituting a hydrogen item with CH3. The author of the Science study, Jeff Riffell, told me in an email that this could be why these two compounds, which come from such disparate sources, elicit similar responses in the brains of moth.

6000-year-old flatworm egg is the oldest confirmed case of schistosomiasis

Paleopathologists found a 6000-year-old schistosome egg, (which causes the dreaded disease schistosomiasis or bilharzia in developing countries today) in a child's remains in ancient Mesopotamia. They believe the find points to the major role agricultural technologies played in the spread of infectious diseases among humans.

On the chances of Sun turning around Ranbaxy

A short piece on Sun's chances with reviving Ranbaxy. Most analysts I spoke to thought the valuation was too high for a company with so many regulatory problems. http://forbesindia.com/article/big-bet/sun-has-a-better-shot-than-most-at-ranbaxy-turnaround/37664/1

Fund crunch follows talent crunch at OSDD

This month, Forbes India published my article on how a talent crunch is hampering progress for India's open source drug discovery program. Yet, this program is very valuable in the training and exposure it provides to pharmaceutical researchers and the expertise it will create for the drug development industry, going forward. Sadly, soon after my article was published, there were news reports on OSDD running out of funds, because the cabinet did not sanction the earmarked funds in time. Now, OSDD has to wait till the elections are over for the funding cycle to start again. See Business World's report here:  http://www.businessworld.in/news/economy/funds-crunch-hits-india-s-drug-development-project/1319301/page-1.html . A pathetic state of affairs.
