A new method for visual impairment treatment has been discovered by researchers of the Institute of Human Brain, Russian Academy of Sciences. The patients suffering from visual impairment can be helped if a healthy donor’s cerebrospinal fluid is introduced to the parent’s vertebral canal – this method is called liquortransfusion. Physiologists have determined that the method is effective even when prescription of visual impairment exceeds five years. Eyesight improves with 83 percent of patients.
The reasons that deprive people of the ability for normal vision are multifarious – these are not only eye diseases, but also lesions of optic nerve, visual tracts and visual centers in the cerebrum. Till recently, physicians believed that effective treatment of visual system was possible only at early stages when no more than three months elapsed since the onset. Treatment at later stages was normally unsuccessful. Now physicians have the opportunity to restore vision of the patients who suffered visual impairment five and more years ago.
The method of endolumbal introduction (into the vertebral canal) of a healthy donor’s cerebrospinal fluid has been applied for several years already by specialists of the Institute of Human Brain, Russian Academy of Sciences. They have taken out a patent of the Russian Federation for application of this method for treatment of heavy neurologic patients who lost the ability for normal seeing. The donors are healthy volunteers, usually relatives of the patients. The cerebrospinal fluid (liquor) is transfused either immediately after it is taken from the donor or after short-term conservation and sterilization. Likewise blood transfusion, the group should be taken into account – the researchers have discovered four groups of cerebrospinal fluid (liquor) similar to four groups of blood.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
