Kochi, Feb 21 : Promising new lease on life to cancer patients across the world, a young scientist from Kerala has developed a cost effective and less toxic nano medicine to cure cancer.

The medicine is claimed to be very effective for oral, brain and pancreatic cancers and is also cost effective with minimum side effects compared to existing drugs in the market.

The medicine begins to work within 48 hours after being injected into a patient and 90 per cent of it would accumlate in the cancer tissue compared to other medicines, Dr Manszoor Koyakutty, who developed the medicine told UNI.

In contrast to the present system of photo therapy, where the medicine passes though the entire body of a patient, instead of the affected part and the patient prohibited to light for one month as it turns toxic, the new medicine is named as photo dynamic therapy.

It is 60 per cent cheaper than photo therapy system, which costs Rs 6000 per dose. A patient has to take a minimum of four doses, he said. (UNI)

Medication via remote-control instead of a shot? Scientists implanted microchips in seven women that did just that, oozing out the right dose of a bone-strengthening drug once a day without them even noticing.

Implanted medicine is a hot field, aiming to help patients better stick to their medications and to deliver those drugs straight to the body part that needs them.

But Thursday's study is believed to be the first attempt at using a wirelessly controlled drug chip in people. If this early-stage testing eventually pans out, the idea is that doctors one day might program dose changes from afar with the push of a button, or time them for when the patient is sleeping to minimise side effects.

The implant initially is being studied to treat severe bone-thinning osteoporosis. But it could be filled with other types of medication, said co-inventor Robert Langer of the Massachusetts Institute of Technology.

'It's like Star Trek,' said Langer, referring to a science fiction television series. He co-authored the study appearing on Thursday in the journal, Science Translational Medicine. 'Just send a signal over a special radio wave, and out comes the drug.'

Today's medication implants continuously emit their drugs until they run dry. One example is a coin-sized wafer that oozes chemotherapy directly onto the site of a surgically removed brain tumour, targeting any remaining cancer cells. Another is a contraceptive rod that is implanted in the arm and releases hormones to prevent pregnancy.

A next step would be more sophisticated implants that release one dose at a time, programmable to skip or add a dose as needed, said biomedical engineer Ellis Meng of the University of Southern California.

Meng was not involved with the MIT study but also is developing this kind of technology, and called Thursday's report 'an important milestone'.

Women with severe osteoporosis sometimes are prescribed daily injections of the bone-building drug teriparatide, known by the brand, Forteo. But many quit taking it because of the hassle of the shots.

In the study, the microchip held doses of that drug inside tiny wells that are sealed shut with a nano-thin layer of gold. Sending a wireless signal causes the gold on an individual well to dissolve, allowing that dose to diffuse into the bloodstream, Langer explained.

In a doctor's-office procedure, the microchip was implanted just below the waistline into eight women with osteoporosis in Denmark. Testing found one microchip wasn't responding to the signals. The other seven women had their implants programmed to automatically emit a once-a-day dose beginning eight weeks later.

The chips could have begun working right away, said Robert Farra, chief executive of MicroCHIPS Inc, a Massachusetts company that has licensed the device and funded the study. But animal research showed a scar tissue-like membrane forms around the pacemaker-sized implant. So he waited until that blockage formed to signal the first of 20 once-a-day doses to begin, to see if the drug could get through.

Blood testing showed the implant delivered the drug as effectively as the women's usual daily injections, and the device appeared to be safe, the researchers reported.

It will take large-scale studies to prove the implant works as well as the long-used shots, cautioned osteoporosis specialist Dr Ethel Siris of New York-Presbyterian Hospital/Columbia University.

'They're a long way from proving that this mode of administration is going to work,' she said. But it's an intriguing idea because 'it's daunting to have to take a daily shot'.

Farra said his company hopes to begin a larger-scale test, using a chip that can hold 365 doses, in 2014. While doses of this osteoporosis medicine typically are not adjusted, he said, the eventual goal is for patients to carry a mobile phone-sized device that would provide wireless feedback to the doctor who programs their implants.
