levitation to improve the drug development process

levitation to improve the drug development process | Medical Engineering = MEDINEERING | Scoop.it

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have discovered a way to use sound waves to levitate individual droplets of solutions containing different pharmaceuticals.

The acoustic levitator uses two small speakers to generate sound waves at frequencies slightly above the audible range – roughly 22 kilohertz. When the top and bottom speakers are precisely aligned, they create two sets of sound waves that perfectly interfere with each other, setting up a phenomenon known as a standing wave.

At certain points along a standing wave, known as nodes, there is no net transfer of energy at all. Because the acoustic pressure from the sound waves is sufficient to cancel the effect of gravity, light objects are able to levitate when placed at the nodes.

 

As drugs are far better if they can be produced (an maintained) in their amorphous state, and if a solution evaporates in contact with a container's wall turns into its crytalline form , the scientists used the acoustic levitation to prevent the droplets touching anything but air

 

Interesting video, by the way

DARPA's Cheetah Bolts Past the Competition

DARPA's Cheetah robot—already the fastest legged robot in history—just broke its own land speed record of 18 miles per hour (mph). In the process, Cheetah also surpassed another very fast mover: Usain Bolt. According to the International Association of Athletics Federations, Bolt set the world speed record for a human in 2009 when he reached a peak speed of 27.78 mph for a 20-meter split during the 100-meter sprint. Cheetah was recently clocked at 28.3 mph for a 20-meter split. The Cheetah had a slight advantage over Bolt as it ran on a treadmill, the equivalent of a 28.3 mph tail wind, but most of the power Cheetah used was to swing its legs fast enough, not to propel itself forward.

Laser beams as guiding tool for 3D painting-printing | Medical Engineering = MEDINEERING | Scoop.it

Vienna University of Technology.

 

There are many ways to create three dimensional objects on a micrometer scale. But how can the chemical properties of a material be tuned at micrometer precision? Scientists at the Vienna University of Technology developed a method to attach molecules at exactly the right place. When biological tissue is grown, this method can allow the positioning of chemical signals, telling living cells where to attach. The new technique also holds promise for sensor technology: A tiny three dimensional “lab on a chip” could be created, in which accurately positioned molecules react with substances from the environment.

The Bionic Eye from Bionic Vision Australia

The Bionic Eye from Bionic Vision Australia | Medical Engineering = MEDINEERING | Scoop.it

Bionic vision technology aims to restore the sense of vision to people living with blindness and low vision. Initially,  BVA targets patients with retinitis pigmentosa and age-related macular degeneration.

Video at http://www.bionicvision.org.au/eye

 

In a major development, Bionic Vision Australia researchers have successfully performed the first implantation of an early prototype bionic eye with 24 electrodes.

Ms Dianne Ashworth has profound vision loss due to retinitis pigmentosa, an inherited condition. She has now received what she calls a ‘pre-bionic eye’ implant that enables her to experience some vision. 

After years of hard work and planning, Ms Ashworth’s implant was switched on last month at the Bionics Institute, while researchers held their breaths in the next room, observing via video link.

 

“I didn’t know what to expect, but all of a sudden, I could see a little flash…it was amazing. Every time there was stimulation there was a different shape that appeared in front of my eye,” Ms Ashworth said.

Regenerative Medicine: A Peek into the Future

Regenerative Medicine: A Peek into the Future | Medical Engineering = MEDINEERING | Scoop.it
Regenerative medicine is a growing field that offers the potential to repair and replace damaged cells, tissues, and organs by using those that are specially grown.

 

Scientists in fields ranging from biology, genetics, physiology, nanotechnology, and pharmacology work collaboratively to contribute to three sub-fields of regenerative medicine: tissue engineering, cell therapies, and healing therapies. Tissue engineers focus on growing connective tissues and replacement organs for the body. They test their work on animals before implementing it into humans. Scientists in cell therapy try to stimulate reparation from the diseased tissue or organ itself. They identify and optimize the factors that lead to self-reparation of the organ. Healing therapists study strategies to restore the functions of an implanted tissue or organ

Researchers Create Short-Term Memories In-Vitro

Ben W. Strowbridge, PhD, Professor of Neurosciences and Physiology/Biophysics, and Robert A. Hyde have discovered how to store diverse forms of artificial short-term memories in isolated brain tissue.
Understanding normal memory function also lays the groundwork for understanding how neurodegenerative diseases, such as Alzheimer’s or Parkinson's disease, affect memory and for developing new, more effective treatments for memory impairments associated with aging.

 

“This is the first time anyone has found a way to store information over seconds about both temporal sequences and stimulus patterns directly in brain tissue,” says Dr. Strowbridge. “This paves the way for future research to identify the specific brain circuits that allow us to form short-term memories.”

The researchers also demonstrated that they could generate memories for specific contexts, such as whether a particular pathway was activated alone or as part of a sequence of stimuli to different inputs. Changes in ongoing activity of hippocampal neurons accurately distinguished between two temporal sequences, akin to humans recognizing the difference between two different song melodies.

StethoCloud - Helping diagnosis of Pneumonia with a smartphone

StethoCloud - Helping diagnosis of Pneumonia with a smartphone | Medical Engineering = MEDINEERING | Scoop.it

Pneumonia is an infection of the lungs, filling them with fluid. It causes  more than 50% of pneumonia deaths in children under 5 years of age, 98% of these deaths occurring in developing nations. 

 

The systems consists on a stethomic (a a low-cost digital stethoscope prototyped from off-the-shelf components) and several 

Apps for Windows Phone, Android and legacy J2ME compatible phones. 

 

"StethoCloud is unique from other digital stethoscopes because we harness the power of cloud computing to create the artificial intelligence that makes our stethoscopes "smart".

By using scalable cloud storage facilities provided by Microsoft's Windows Azure platform, we are building the world's largest database on breath and heart sounds. Through this database, we will be able to train our machine learning algorithms to extract features and perform knowledge discovery of breath sound patterns and their related pathologies. This training will enable the machine to accurately diagnose pneumonia, asthma and other respiratory diseases with at least the same level of sensitivty and specificity as human diagnosticians.

Multidisciplinary team to develop a noninvasive brain-machine interface to a robotic device to help upper-limb rehabilitation

Multidisciplinary team to develop  a noninvasive brain-machine interface  to a robotic device to help upper-limb rehabilitation | Medical Engineering = MEDINEERING | Scoop.it

The team lead by José Luis Contreras-Vidal, director of UH’s Laboratory for Noninvasive Brain-Machine Interface Systems and a professor of electrical and computer engineering, with Rice University and the University of Houston, are developing a robot controlled by brain waves to help in the rehabilitation of stroke survivors.

Rice is developing the exoskeleton and UH the electro-encephalograph-based (EEG) neural interface. 

The team was the first to successfully reconstruct 3-D hand and walking movements from brain signals recorded in a noninvasive way using an EEG brain cap. The technology allows users to control, with their thoughts, robotic legs and below-elbow amputees to control neuroprosthetic limbs.

In this way and by means of repetitive exercise, the user re-trains the damaged motor pathways effectively.

Smart Sutures That Detect Infections

Smart Sutures That Detect Infections | Medical Engineering = MEDINEERING | Scoop.it

Surgical sutures are mindless threads no more. Researchers have now coated them with sensors that could monitor wounds and speed up healing.

The electronic sutures, which contain ultrathin silicon sensors integrated on polymer or silk strips, can be threaded through needles, and in animal tests researchers were able to lace them through skin, pull them tight, and knot them without degrading the devices.

The sutures can precisely measure temperature—elevated temperatures indicate infection—and deliver heat to a wound site, which is known to aid healing. And John Rogers, professor of materials science and engineering at the University of Illinois at Urbana-Champaign and inventor of the smart sutures, imagines that they could also be laden with devices that provide electrical stimulation to heal wounds. "Ultimately, the most value would be when you can release drugs from them in a programmed way," he says. The researchers could do that by coating the electronic threads with drug-infused polymers, which would release the chemicals when triggered by heat or an electrical pulse.
