The Hundred-Year Quest

Over 20 years after creating the Edmonton Protocol, a process celebrated as a possible ‘cure’ for diabetes, Dr James Shapiro is at it again. This time, using stem cells. The academic in Canada is researching a new possibility of engineering stem cells to become the insulin-producing islet cells found in the pancreas.

Dr Shapiro explains: “The biggest challenges with the Edmonton protocol approach, where we use cells taken from organ donors, are that we have to use organ donors. When we think about the enormous burden of diabetes worldwide, 463 million people with all forms of diabetes, it’s been clear all along that there would never be enough cells to go around to treat that kind of patient base if the organ donor approach became a therapy for all diabetes. The second, perhaps bigger, limitation is that those donor cells are allogeneic. In other words, they’re foreign to the body. Because of that, anti-rejection drugs have to be given just like any other organ transplant, like a heart, lung, or liver, or those cells will be rejected by the body. To overcome those two challenges, it became clear to us that stem cells provided a unique opportunity to fix both the supply problem and the anti-rejection problem.”

Rotech launch new modular conveyors to simplify packaging coding

Rotech Machines, one of the UK’s leading manufacturers of coding and marking technology, has launched a new range of high-quality modular conveyor systems, designed specifically for food, pharmaceutical, medical and industrial packaging operations. The small, modular, interlocking conveyors offer customers greater packing and coding flexibility, allowing users to pack goods and print codes at speed in any location. The all-in-one conveyor systems are particularly beneficial where space is limited, where coding and packing is currently performed in different locations, or where a conventional industrial conveyor is too large.
