Misdiagnosis of a severely paralyzing disease can now be averted due to a blood test developed by Mayo Clinic researchers and their Japanese collaborators. Often misdiagnosed as multiple sclerosis, neuromyelitis optica (NMO) also causes blindness in many sufferers. The findings of this international collaborative effort appear in the current issue of The Lancet.
The finding will help doctors correctly treat NMO -- also known as Devics syndrome -- sooner and more effectively. In some countries, misdiagnosis may be as high as 30 percent. Early diagnosis is important because NMO is best treated differently than multiple sclerosis. Treatment requires immune suppressive medications in the first instance, rather than the immune modulatory treatments typically prescribed for MS. Therefore, a patient who has NMO, but is misdiagnosed with MS, may not receive optimal care at the earliest possible time.
NMO affects the optic nerves and spinal cord -- and within five years causes half of affected patients to lose vision in at least one eye. Many lose the ability to walk independently. The prognosis for loss of sight and permanent paralysis is much worse for patients who have NMO than for those who have MS. MS is not confined to optic nerve and spinal cord involvement. However, the symptoms of the two diseases overlap, and optic nerve and spinal cord involvement occur in both. NMO is particularly difficult to distinguish from MS in the early phases of the disease.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
