Grow a new brain: First steps to lab-made grey matter

Posted by in category: biotech/medical

11 December 2013 by Rowan Hooper

BIOENGINEERS dream of growing spare parts for our worn-out or diseased bodies. They have already succeeded with some tissues, but one has always eluded them: the brain. Now a team in Sweden has taken the first step towards this ultimate goal.

Growing artificial body parts in the lab starts with a scaffold. This acts as a template on which to grow cells from the patient’s body. This has been successfully used to grow lymph nodes, heart cells and voice boxes from a person’s stem cells. Bioengineers have even grown and transplanted an artificial kidney in a rat.

Growing nerve tissue in the lab is much more difficult, though. In the brain, new neural cells grow in a complex and specialised matrix of proteins. This matrix is so important that damaged nerve cells don’t regenerate without it. But its complexity is difficult to reproduce. To try to get round this problem, Paolo Macchiarini and Silvia Baiguera at the Karolinska Institute in Stockholm, Sweden, and colleagues combined a scaffold made from gelatin with a tiny amount of rat brain tissue that had already had its cells removed. This “decellularised” tissue, they hoped, would provide enough of the crucial biochemical cues to enable seeded cells to develop as they would in the brain.

Britain aiming to cure dementia, says Cameron

Posted by in categories: biotech/medical, health, life extension

by RHIANNON EDWARD

a TREATMENT to cure or halt dementia by 2025 is “within our grasp”, Prime Minister David Cameron said yesterday, as he announced a doubling in UK funding for research.

Mr Cameron was addressing scientists, politicians and campaigners from around the world who have gathered in London for a dementia summit called by the UK as part of its year-long chairmanship of the G8.

With the World Health Organisation (WHO) forecasting that the number of dementia sufferers will almost double worldwide every two decades, Mr Cameron has said he wants UK government investment in dementia research to rise from £66 million in 2015 to £122m in 2025, with similar increases from the commercial and charitable sectors.

Soldier controls bionic arm using power of thought

Corporal Andrew Garthwaite with the defence minister Anna Soubry

A soldier whose arm was blown off by a rocket-propelled grenade in Afghanistan has become the first person in the UK to master a prosthetic limb controlled by thought.

Corporal Andrew Garthwaite, 26, has spent two years learning how to move the arm and grip objects after a six-hour operation to have the limb wired into his body at a medical facility in Vienna.

In addition to being aware and adaptable and resilient before the driving forces reshaping the current present and the as-of-now future, there are some extra management suggestions that I concurrently practice:

1. Given the vast amount of insidious risks, futures, challenges, principles, processes, contents, practices, tools, techniques, benefits and opportunities, there needs to be a full-bodied practical and applicable methodology (methodologies are utilized and implemented to solve complex problems and to facilitate the decision-making and anticipatory process).

The manager must always address issues with a Panoramic View and must also exercise the envisioning of both the Whole and the Granularity of Details, along with the embedded (corresponding) interrelationships and dynamics (that is, [i] interrelationships and dynamics of the subtle, [ii] interrelationships and dynamics of the overt and [iii] interrelationships and dynamics of the covert).

How nanotechnology can trick the body into accepting fake bones

Posted by in categories: biotech/medical, health, nanotechnology

Altering the surface of orthopaedic implants has already helped patients – and nanotech can fight infections too

One of medicine’s primary objectives is to trick the body into doing something it doesn’t want to do. We try to convince our immune systems to attack cancer cells (our immune systems don’t normally attack our own bodies), we try to convince neurons to regrow (another unnatural phenomenon), and we try to convince the body to accept foreign bits, such as someone else’s kidney or a fake bone. In order to accomplish this, we try to make parts of our bodies we don’t want, such as cancers, look foreign. We try to make foreign bits that we do want, such as orthopaedic implants, look natural. Nanotechnology, as you might have guessed, can help us do just that.

IBM Creates Nanotechnology to Battle Fungal Infections

Posted by in categories: biotech/medical, environmental, nanotechnology

Tim Parker, Benzinga Staff Writer

Before scientists create something that has mainstream uses, it often starts as science fiction.

A new technology deep within IBM’s (NYSE: IBM [FREE Stock Trend Analysis]) Singapore research facility isn’t quite ready for the mainstream but when it is, the implications for those who suffer from fungal infections and later, other infections, could have a new ally in their fight but this ally is completely different than current treatments.

If you’re a fan of Star Trek, you’ve seen nanotechnology. These are microscopic machines that get inside machines or in this case, the body, to identify and fix problems.

New artificial, bionic hands start to get real feelings

Posted by in categories: bionic, biotech/medical

Bebionic3

Simple tasks, like plucking the stem off a cherry, are still monumental challenges for artificial hands. With a bill of materials perhaps a few hundred components long, it is not surprising that their functionality is low compared with one assembled from trillions of components. A new prosthetic bionic hand, designed and built by researchers at Case Western University is now capable of using measurements from 20 sensor points to control the grip force of its digits. Incredibly, the sensor data is linked directly to the sensory nerves in the patient’s forearm. The control for the grip closure is then extracted myoelectrically from the normal biological return loop to the muscles in the forearm.

Google Glass Makes Its Way Into Operating Rooms

Posted by in categories: biotech/medical, health

Written By:

surgery

Hands-free devices like Google Glass can be really transformative when the hands they free are those of a surgeon. And leading hospitals, including Stanford and the University of California at San Francisco, are beginning to use Glass in the operating room.

In October, UCSF’s Pierre Theodore, a cardiothoracic surgeon, became the first doctor in the United States to obtain Institutional Review Board approval to use the device to assist him during surgery. Theodore pre-loads onto Glass the scans of images of the patient taken just before surgery and consults them during the operation.

How 3D Printers Are Cranking Out Eyes, Bones, and Blood Vessels

At the dawn of rapid prototyping, a common predication was that 3D printing would transform manufacturing, spurring a consumer revolution that would put a printer in every home. That hasn’t quite happened—-and like so many emerging technologies, rapid prototyping has found its foothold in a surprisingly different field: Medicine.

The following studies and projects represent some of the most fascinating examples of “bioprinting,” or using a computer-controlled machine to assemble biological matter using organic inks and super-tough thermoplastics. They range from reconstructing major sections of skull to printing scaffolding upon which stem cells can grow into new bones. More below—and look out for more 3D printing week content over the next few days.
