Bone marrow stromal cells release a blood vessel-dilating hormone found in the brain -- a finding that suggests the hormone may be tapped to help with recovery from stroke or other neurological injuries disrupting blood flow to the central nervous system, researchers at the University of South Florida and James A. Haley Veterans Hospital report for the first time. The hormone is known as brain natriuretic peptide.
The laboratory study was published in the January 2004 issue of the journal Experimental Neurology.
"Were suggesting that transplanted bone marrow stromal cells may hasten recovery by releasing brain natriuretic peptide and other factors that improve blood flow to the brain and decrease swelling and pressure around the site of injury," said lead investigator Juan Sanchez-Ramos, MD, PhD, professor of neurology and research director at the USF Center for Aging and Brain Repair. "By helping irrigate, or restore the blood circulation to the brain, brain natriuretic factor may reduce the extent of damage from stroke or spinal cord injuries."

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
