Plasma could help bones heal faster

Plasma could help bones heal faster
Cold plasma, which is made of electrons that change polarity at micro-second or nanosecond speeds, could help bones heal faster, according to a study published in the Journal of Tissue Engineering and Regenerative Medicine. Most people interact with plasma every day. It's in our TVs, fluorescent lights, lightning, the aurora borealis, and the sun. However, these are all examples of hot or "thermal" plasmas.

Process could lead to better gene therapies

Process could lead to better gene therapies
Michigan Technological University scientists have developed a process that could lead to stickier—and better—gene therapy drugs. The drugs, called antisense DNA, are made from short, single strands of synthetic DNA. They work by blocking cells from making harmful proteins, which can cause maladies ranging from cancer to Ebola to HIV-AIDS. Only a couple of these synthetic DNA drugs are on the market, but a number are in clinical trials, including a potential treatment for ALS, also known as Lou Gehrig's disease.

DNA condensation is carried out on a biochip

DNA condensation is carried out on a biochip
Normally, individual molecules of genetic material repel each other. However, when space is limited DNA molecules must be packed together more tightly. This case arises in sperm, cell nuclei and the protein shells of viruses. An international team of physicists has now succeeded in artificially recreating this so-called DNA condensation on a biochip. Recreating important biological processes in cells to better understand them currently is a major topic of research.

Growing living bone for facial reconstruction

Growing living bone for facial reconstruction
Researchers have engineered living bone tissue to repair bone loss in the jaw, a structure that is typically difficult to restore. The team led by researchers from Columbia University, New York, grafted customised implants into pig jaws that resulted in integration and function of the engineered graft into the recipient's own tissue. The work, reported in Science Translational Medicine, suggests that personalised bone grafts for facial reconstruction may be possible in the future.

Magnetic field helps avoid implants rejection

A group of Russian physicists, with the contribution from their Swiss colleagues, developed a way to use the therapeutic effect of heating or cooling the tissues due to the magnetocaloric effect. The article with the results of the work was published in the latest issue of the International Journal of Refrigeration. A team of the Lomonosov Moscow State University scientists proposed a way to use the magnetocaloric effect for the targeted delivery of drugs to the implants.

Microfluidic chip replicates muscle-nerve connection

Microfluidic chip replicates muscle-nerve connection
MIT engineers have developed a microfluidic device that replicates the neuromuscular junction - the vital connection where nerve meets muscle. The device, about the size of a U.S. quarter, contains a single muscle strip and a small set of motor neurons. Researchers can influence and observe the interactions between the two, within a realistic, three-dimensional matrix. The researchers genetically modified the neurons in the device to respond to light.

Lab-on-a-chip technology helps cancer detection

Lab-on-a-chip technology helps cancer detection
IBM scientists have developed a lab-on-a-chip technology that can, for the first time, separate biological particles at the nanoscale and could enable physicians to detect diseases such as cancer before symptoms appear. As reported today in the journal Nature Nanotechnology, the IBM team's results show size-based separation of bioparticles down to 20 nm in diameter, a scale that gives access to important particles such as DNA, viruses and exosomes.

Singapore scientists grow mini human brains

Singapore scientists grow mini human brains
Scientists in Singapore have made a big leap on research on the 'mini-brain'. These advanced mini versions of the human midbrain will help researchers develop treatments and conduct other studies into Parkinson's Disease[1] (PD) and ageing-related brain diseases. These mini midbrain versions are 3D miniature tissues that are grown in the laboratory and they have certain properties of specific parts of the human brain.

Inflammatory response to ceramic scaffolds promotes bone regeneration

Inflammatory response to ceramic scaffolds promotes bone regeneration
In their mission to design biomaterials that promote tissue regeneration, Drexel University researchers have identified how inflammation, when precisely controlled, is crucial to bone repair. Their findings, published in the Journal of the Royal Society Interface, show that a new type of ceramic scaffold causes inflammatory cells to behave in a way that is more regenerative than scaffolds that are currently used clinically.

Virtual brain aids the investigation of epilepsy

Virtual brain aids the investigation of epilepsy
Researchers at CNRS, INSERM, Aix-Marseille University and AP-HM have just created a virtual brain that can reconstitute the brain of a person affected by epilepsy for the first time. From this work we understand better how the disease works and can also better prepare for surgery. These results are published in Neuroimage. Worldwide, one percent of the population suffers from epilepsy.
