Should we start being genetically tested for Parkinson’s disease (PD)? According to research just published in the December issue of the "journal Movement Disorders" this might be a possibility in the future if you belong to a family affected by G2019S, a genetic mutation responsible for some PD cases.
Parkinson disease results from the death or loss of function of the nervous cells (neurons) in a brain area called substancia nigra, which is involved in the regulation of movement. Neurons within this region produce dopamine, a neurotransmitter that acts as messenger between the substancia nigra (the control centre) and other neurons around the body, leading to a correct regulation of the body movements. If the substancia nigra degenerates, like it happens in PD, dopamine is no longer properly produced and the individual starts presenting the typical symptoms of Parkinson’s disease such as slowed movements, tremors, loss of movement control and rigidity.
Although there is still no cure, treatments, which increase the brain’s dopamine levels, are relatively effective. Unfortunately, as disease progresses, treatment becomes less and less efficient and the patient’s full deterioration is inevitable. The disease affects about 1% of the world population with, only in the US, half a million people affected and about 50,000 new cases are reported every year, a number predicted to increase as the average age of the populations also increases.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
