Researchers have used a £1,250 system to create a range of organic compounds and inorganic clusters – some of which are used to create cancer treatments.
Longer term, the scientists say the process could be used to make customised medicines.
They predict the technique will be used by pharmaceutical firms within five years, and by the public within 20.
"We are showing that you can take chemical constituents, pass them through a printer and create what is effectively a chemical synthesiser in which the reaction occurs allowing you to get out something different at the end," researcher Mark Symes told the BBC.
"We're extrapolating from that to say that in the future you could buy common chemicals, slot them into something that 3D prints, just press a button to mix the ingredients and filter them through the architecture and at the bottom you would get out your prescription drug."

'Revolutionising healthcare'
The 3D printing process involves the use of a robotically controlled syringe which builds an object out of a gel-based "ink", into which chemicals and catalysts are mixed.
"Chemists normally put chemicals in glassware to create a reaction," said Prof Lee Cronin, who came up with the idea.
"What we are doing is mixing the concept of the glassware and the chemicals together in the 3D printer to create what we call 'reactionware'.
"It's almost like a cake – you print the last reactionary agent first and then build other chemical layers above, finally adding a liquid at the top. The liquid goes to layer one making a new molecule which goes to the next layer creating another and so on until at the bottom you get your prescription drug out."
Until now the researchers have used bathroom sealant to create their reactor, and the substances created have not been suitable for human consumption.

But the scientists say their next step is to switch ingredients and replicate drugs already available in pharmacies. They also hope to work with engineers to increase the printer's speed and resolution. If successful, they say doctors and individuals could ultimately download pre-set recipes and even tailor medicines to their individual needs.
"This would not only place traditionally expensive chemical engineering technology within reach of typical laboratories and small commercial enterprises, but also could revolutionise access to healthcare and the chemical sciences in general in the developing world," they wrote in a paper published in the Nature Chemistry journal.

  Refugee team to compete at Olympics in Rio

 

 

A team of refugees will be allowed to compete at the Olympics in Rio, in Brazil, under the

Olympic flag.

Between five or ten athletes are expected to make up the final team.

They will use the Olympic flag and the Olympic anthem instead of their own countries´ flag

[5] or national anthem.

Athletes have been able to take part in the Olympic games under the banner of the

Olympic flag and have been classed as independent athletes in the past.

Rio 2016 will be the first time that refugees, who have fled their home countries, will be

able to compete in this way.

[10] International Olympic Committee president Thomas Bach said: "By welcoming the team of

refugee Olympic athletes to the Olympic Games Rio 2016, we want to send a message of

hope for all refugees in our world.

"Having no national team to belong to, having no flag to march behind, having no national

anthem to be played, these refugee athletes will be welcomed to the Olympic Games with

[15] the Olympic flag and with the Olympic anthem."

“'Major' Ketamine Discovery May Lead to New Antidepressants

 

  The possibility of an antidepressant that delivers ketamine's rapid antidepressant effects but none of its potential harms may be one step closer, new research shows.

  Investigators at the National Institute of Health (NIMH) have discovered that ketamine rapidly lifts depression via a by-product of its metabolism. This metabolite singularly reversed depression-like behaviors in mice without triggering any of the anesthetic, dissociative, or addictive side effects associated with ketamine.

  "This discovery changes our understanding of how this rapid antidepressant mechanism works and holds promise for the development of more robust and safer treatments," study investigator Carlos Zarate, MD, National Institute of Mental Health, Methesda, Maryland, said in a statement."Ketamine is a reasonable option to consider when patients have tried everything else, as long as it's in the right hands and given at the right time," Dr Zarate told Medscape Medical News."But if you had an alternative drug that works rapidly but which doesn't have any risk of addiction or cause any of ketamine's side effects, you open up the possibility of many others being able to receive an alternative to ketamine," he added.

The study, led by Panos Zanos, PhD, University of Maryland School of Medicine, Baltimore, was published online May 4^th in Nature.‖
