Bionic Muscles Could Find Use in Robots

Bionic Muscles Could Find Use in Robots | Medical Engineering = MEDINEERING | Scoop.it
Hybrid materials made of cardiac cells and carbon nanotubes might patch damaged hearts and provide muscle for robots made of living tissues.
Carlos Garcia Pando's insight:

Another step to the TERMINATOR: external flesh and muscles covering an internal metalic skeleton.

 

The bionic tissues, made by Ali Khademhosseini, a professor at the Harvard-MIT Division of Health Sciences and Technology in Cambridge, Massachusetts, could serve as muscles for biological machines—moving, programmable living tissues that take synthetic biology beyond single cells. A lot of the things that natural tissues and biological cells can do, such as sense and respond to their environment, are hard for engineers to achieve with the synthetic materials used in conventional robotics. Researchers hope that building machines from biological materials like heart tissue will expand what’s possible. The new tissues can swim untethered in water, swing back and forth, and perform other moves programmed by controlling their shape and thickness

A new surgical procedure to reconnect sensory neurons to spinal cord after injury; spinal cord offshoots complete spinal circuit. 

A new surgical procedure to reconnect sensory neurons to spinal cord after injury; spinal cord offshoots complete spinal circuit.  | Medical Engineering = MEDINEERING | Scoop.it

In a recent clinical report, return of the tendon stretch reflex was demonstrated after spinal cord surgery in a case of total traumatic brachial plexus avulsion injury. Peripheral nerve grafts had been implanted into the spinal cord to reconnect to the peripheral nerves for motor as well as sensory function.

 
Carlos Garcia Pando's insight:
Thomas Carlsted at King's College London recently helped to develop a new surgical technique to reconnect the sensory root. It involves cutting the original sensory nerve cells out of the root and implanting the remaining root directly into a deeper structure in the spinal cord.

Repair of critical sized cranial defects with BMP9-transduced calvarial cells delivered in a thermoresponsive scaffold | Medical Engineering = MEDINEERING | Scoop.it

Large skeletal defects caused by trauma, congenital malformations, and post-oncologic resections of the calvarium present major challenges to the reconstructive surgeon.

 
Carlos Garcia Pando's insight:
Interestingly, the regenerated bone was better quality, the bone growth was contained to the area defined by the scaffolding, the area healed much more quickly, and the new and old bone were continuous with no scar tissue.
The scaffold is reabsorbed

Non-invasive measurement of Blood Glucose

Non-invasive measurement of Blood Glucose | Medical Engineering = MEDINEERING | Scoop.it
Researchers have developed a method of measuring blood glucose using far infrared light, which is both harmless and non-invasive.
Carlos Garcia Pando's insight:

As opposite to near infrared only weakly absorbed by glucose, but also by water, protein and hemoglobin, far infrared light with wavelengths of around 10 micron is strongly absorbed by glucose, making it possible, in theory, for patients to get more sensitive and accurate measurements.

However, the problem faced by researchers, is that far-infrared light penetrates only a few microns from the skin's surface, which makes the detection of blood glucose difficult.

Prof. Matsuura's team has thus developed a new measurement technique that consists of a small prism attached to the ends of flexible hollow-optical fibers to radiate far infrared light. By using this method, it is possible to irradiate the oral mucosa of inner lips that, unlike skin, have no thick horny layer.

An effective yet simple demonstration of how Next-generation genetic sequencing is useful; furthermore: cheap

An effective yet simple demonstration of how Next-generation genetic sequencing is useful; furthermore: cheap | Medical Engineering = MEDINEERING | Scoop.it
Mystery Boy Brandon Keesing was incorrectly diagnosed with a degenerative muscular disease until revolutionary genetic sequencing gave him life-changing news.

 

Originally thought that Keesing has a mitochondrial disease, doctors had been wrong all along. Revolutionary advances in genetic sequencing proved he did not have mitochondrial disease at all. "In recent years the capacity to read the genetic code of every single gene — all 20,000 of them in the human body — has reached a point where it is now efficient, accurate, cost-effective to be able to do this," he says.


The new technique is called "next generation sequencing" — and where previously it took weeks or months to analyse the code of a single gene, today laboratory computers can decode all 20,000 genes in one go.


Almost immediately Westmead Children's Hospital researchers could pinpoint which one of Brandon's genes had a mutation. Professor Christodoulou illustrates how the technique works on a chart. "So here in the unaffected individual we have an 'A'. Here in the affected individual we have a 'G'. And that's precisely where the mistake is," he says.


Doctors using next generation sequencing discovered in fact that Brandon had congenital myasthenia — a different genetic disease which also affects the muscles. But although incurable, it is not usually fatal and can be treated with medication.


"The name of the gene that we found the mistakes in is called COLQ, and it has a completely different role," Professor Christodoulou says. "It has nothing to do with mitochondrial energy production. "What it is involved in is co-ordinating the communication of nerve cells with the muscle, so that the muscle, when it receives an impulse from a nerve cell, it contracts and relaxes appropriately.


"So the problem with the COLQ mistakes is that this process couldn't be co-ordinated properly. And that's what actually led to his progressive problems."


Finding that one gene in 20,000 has transformed Brandon's life. A simple drug quickly restored some of his muscle strength. As quickly as he had deteriorated as a toddler, he suddenly began making huge strides.

"We noticed it straight away. By the end of that week he got up off that bed and he walked," she says, wiping away tears. "That was unreal. I'll never forget that day. I was so happy for him and ... I just knew from that he was going to grow, he was going to enjoy his life that much more than what he had before. And he has."


Professor Christodoulou says it was a very gratifying outcome for doctors.

IlluminOss’ minimally invasive technology allows for fracture fixation through patient-specific intramedullary implants using a light-curable polymer, contained within a balloon catheter. The percutaneous surgical approach enables surgeons to create a first-of-its-kind patient-conforming implant providing internal support of bones affected by cancer

Carlos Garcia Pando's insight:

The global fracture repair (trauma) market is more than $5 billion and growing greater than 10 percent annually. An aging, active population suffering from osteoporosis contributes to the growing issue of fragility fractures, those occurring as a result of a fall from standing height. Fragility fractures are common in women over 50 years of age and about half will suffer from one in their lifetime.  In men over 50, the occurrence of fragility fractures is one in five. In more dramatic terms, an osteoporotic fragility fracture is estimated to occur every three seconds
