India doctors remove 232 teeth from boy’s mouth
-
Doctors in India have extracted 232 teeth from the mouth of a 17-year-old boy in a seven-hour operation. Ashik Gavai was brought in with a swelling in his right jaw, Dr Sunanda Dhiware, head of Mumbai’s JJ Hospital’s dental department, told the BBC. The teenager had been suffering for 18 months and travelled to the city from his village after local doctors failed to identify the cause of the problem. Doctors have described his condition as “very rare” and “a world record”.
‘Small white pearls’ “Ashik’s malaise was diagnosed as a complex composite odontoma where a single gum forms lots of teeth. It’s a sort of benign tumour,” Dr Dhiware said. (via BBC News - India doctors remove 232 teeth from boy’s mouth)

Japanese leader proposes first-ever ‘Robot Olympics’
Nations of the world will be sending their most talented athletes to Tokyo in 2020 for the Olympic Games – but if Japanese Prime Minister Shinzo Abe gets his way, they might also be pitting robots against each other.
Abe announced his vision while touring robotics factories in Tokyo and Saitama, which is located just north of the country’s capital. According to Japan’s Jiji Press (translated via Agence France-Presse), the prime minister said a Robot Olympics would be a great way to showcase advances in the field around the globe.
“In 2020, I would like to gather all of the world’s robots and aim to hold an Olympics where they compete in technical skills,” he said.

New microchip promises to streamline and simplify diabetes diagnoses

See on Scoop.it - The future of medicine and health

For people who don’t already know, here’s the difference between type 1 and type 2 diabetes: the body produces little or no insulin in the case of type 1, and isn’t able to utilize the insulin that it does produce in type 2. It’s a significant difference, so it’s important that patients are diagnosed correctly. Thanks to a new microchip developed by a team at Stanford University led by Dr. Brian Feldman, doing so could soon be quicker, cheaper and easier than ever before.

In order to determine that a patient has type 1 diabetes as opposed to type 2, tests must be performed to confirm the presence of tell-tale antibodies in a sample of their blood. These tests must be performed by extensively-trained personnel in a lab, they involve the use of radioactive materials, take days to get results, and cost hundreds of dollars per test.

Because of these factors, the tests are sometimes not even performed, as it’s generally assumed that children will get type 1 and adults will get type 2. In recent years, however, childhood obesity has caused a rise in the number of kids getting type 2, plus there’s also a puzzling increase in adults with type 1.

That’s where the Stanford chip comes in.

It can be incorporated into a hand-held device that could be used in the field with minimal training, delivering results in minutes. The chip doesn’t require any radioactive material, is worth about $20, and can be used for about 15 tests before needing to be replaced. Additionally, it only requires a drop of blood, as opposed to the larger amount needed in the traditional system.

Human blood platelets grown in bone marrow-replicating bioreactor

See on Scoop.it - The future of medicine and health

Scientists have already successfully coaxed stem cells into becoming red blood cells, which could be used to create “man-made” blood for transfusion. Red blood cells, however, aren’t the only component of human blood. Now, researchers at Harvard-affiliated Brigham and Women’s Hospital have also created functional human platelets, using a bioreactor that simulates the medium in which blood cells are naturally produced – bone marrow.

The main role of platelets (also known as thrombocytes) is to stop wounds from bleeding, by essentially “plugging the hole” in the skin with a clot. Without sufficient numbers of them in the blood, spontaneous and excessive bleeding can occur. Such shortages can be caused by diseases, as a result of undergoing chemotherapy, or by other factors. In these situations, transfusions of platelets harvested from donated blood are often necessary.

In previous studies, scientists have successfully gotten induced pluripotent stem cells to change into megakaryocytes – these are the cells that ordinarily sit in the bone marrow and release platelets into the bloodstream. Unfortunately, it’s proven difficult to get those lab-grown megakaryocytes to produce platelets outside of the body.

That’s where Brigham and Women’s new “bioreactor-on-a-chip” comes into the picture. By mimicking bone marrow’s extracellular matrix composition, stiffness, micro-channel size and shear forces, it persuades the megakaryocytes to produce anywhere from 10 to 90 percent more platelets than was previously possible.

New technique could boost internet speeds tenfold

See on Scoop.it - Knowmads, Infocology of the future

Researchers at Aalborg University, MIT and Caltech have developed a new mathematically-based technique that can boost internet data speeds by up to 10 times, by making the nodes of a network much smarter and more adaptable. The advance also vastly improves the security of data transmissions, and could find its way into 5G mobile networks, satellite communications and the Internet of Things.
