Could 3D Printing Replace Plaster Casts?

(Reuters) – Mexican inventors have created a prototype medical cast using 3D printing, that they believe could potentially end the need for cumbersome plaster casts. Sharon Reich has more. Move over plaster cast. There’s a new 3-D printed cast on the block, which means your days may be numbered. The NovaCast was created by Mexican start-up Mediprint and uses an open, 3D-printed, plastic framework. Each 3D-printed cast is custom-made to the exact measurements of the fractured part of the body, which developers say improves recovery time. CO-FOUNDER OF MEDIPRINT, ZAID MUSA BADWAN PERALTA: “It’s lighter than the traditional cast....

Pain-Free Ultrasonic Device Measures Brain Pressure

(Reuters) – Lithuanian scientists pioneer an ultrasonic device to safely and painlessly measure brain pressure. Amy Pollock reports. Measuring pressure inside the skull has meant risky brain surgery under anaesthetic. Now Lithuanian scientists have developed an ultrasound device to do the job much more gently. PROFESSOR AND HEAD OF TELEMATICS (BIOMEDICINE) LABORATORY AT KAULAS UNIVERSITY OF TECHNOLOGY, ARMINAS RAGAUSKAS: “The device consists of just three parts: first of all it is ultrasonic Doppler blood flow meter, which measures blood flow in ophthalmic artery and of course computer and some mechanical parts to fix ultrasonic transducer on to the face...

US Bid to Grow Human Organs for Transplant Inside Pigs

(BBC) – Scientists in the United States are trying to grow human organs inside pigs. They have injected human stem cells into pig embryos to produce human-pig embryos known as chimeras. The embryos are part of research aimed at overcoming the worldwide shortage of transplant organs. The team from University of California, Davis says they should look and behave like normal pigs except that one organ will be composed of human cells. The human-pig chimeric embryos are being allowed to develop in the sows for 28 days before the pregnancies are terminated and the tissue removed for analysis. See...

Nanotechnology Used to Combat Heart Disease

(Digital Journal) – Nanomedicine represents one of the most promising areas of medical technology. In a new application, researchers have used nanoparticles to address the effects of atherosclerosis. Atherosclerosis is a condition where an artery-wall thickens as a result of invasion and accumulation of white blood cells and proliferation of intimal-smooth-muscle cell creating a fibrofatty plaque. The condition can lead to a heart attack, as a result of a blood clot which blocks the blood supply to the heart. To help deal with the disease, researchers have developed special nanoparticles. These particles are designed so that, when they make...

America Has Bacteria Resistant To All Antibiotics Now Biotech

That’s why scientists are concerned: these pieces of DNA called plasmids can be exchanged between bacteria, passing it on to different bugs and creating new virulent strains that could prove deadly and impossible to treat. Georgiou says, eventually, bacteria will always become resistant to antibiotics. Mcr-1 caused a public health panic in China past year, when it was found in both livestock and people. The bacteria has also been found in Europe and Canada. “To the best of our knowledge, this is the first report of mcr-1 in the US”. It was only a matter of time before colistin...
