Medical malpractice cases frequently try to link injuries to the white matter of a newborns brain -- a precursor to cerebral palsy and other disorders -- to the babys delivery, though a new Johns Hopkins study demonstrates that such injuries are more closely associated with neonatal infections.
White matter, the tracts of nerve fibers that communicate messages in the brain, is generally injured at so-called "end zones" between the long, penetrating arteries that supply blood to the brain. These zones are susceptible to the type of fall in cerebral blood flow and oxygen that could occur during complications in delivery, as marked by excess acid in the umbilical cord.
The Hopkins team reviewed medical records of 150 premature babies who had white matter injuries and were born between May 1994 and September 2001. They compared each babys delivery to that of the next healthy baby delivered at the same gestational age (23-24 weeks), looking for causes of problems.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
