Researchers to test if cannabis ingredient can help COPD patients


Researchers from Imperial College London are looking for volunteers to test whether cannabinoids, the active ingredient of cannabis, can be used to alleviate the sensation of breathlessness caused by illnesses such as chronic obstructive pulmonary disease (COPD).

The team are looking for volunteers aged between 50 and 70, who don’t have breathing difficulties.

Dr Elspeth Pickering, clinical research fellow, from Imperial College London and Chelsea and Westminster Hospital, says: “Despite the best efforts of scientists for many years, no one has been able to develop a way to deal with the sensation of breathlessness without suppressing the drive to breathe. Breathlessness can have a major impact on the quality of life for patients with respiratory diseases, and by using a cannabinoid, we hope to find a way to block the mechanism which causes it.”

The researchers believe the cannabinoids could be used to reduce the sensation of breathlessness without depressing the respiratory system.

The study will take a morning on two different days, during which time volunteers will be hooked up to a circuit to regulate and measure their breathing. Carbon dioxide will be added to the air breathed by the volunteers, causing the sensation of breathlessness. This is a safe method of simulating breathlessness as the body naturally produces carbon dioxide.

Afterwards the volunteers will be given a spray which includes tetrahydrocannabinol (THC), the active ingredient in cannabis, which researchers hope will reduce the sensation of breathlessness.

Dr Anita Holdcroft from Imperial College London and Chelsea and Westminster Hospital, and study leader, adds: “The special formulation of the drug as a spray avoids the harmful effects of smoking cannabis. We hope the drug will stop the sensation of breathlessness, potentially providing a new way to deal with respiratory diseases.”

The study will be conducted at Charing Cross Hospital in west London. Volunteers will be paid for their time committed to the study. Volunteers aged between 50 and 70 who don’t have breathing difficulties and wish to take part should call 020 8846 1234 ext. 7055 to register their interest.

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
