Loyola University Health System begins today the national clinical trial using PolyHeme®, an investigational oxygen-carrying blood substitute designed to increase survival of critically injured and bleeding trauma patients at the scene of injury. Loyola has been involved in extensive public education, staff education and paramedic training since its Institutional Review Board for the Protection of Human Research Subjects (IRB) approved the clinical trial in May. Loyola is one of 20-25 Level I trauma centers which will participate in the trial nationwide and the only one in Illinois.
“If the blood substitute works the way we hope it will, it could be the first major advance since the introduction of saline, or salt water, to replace volume after blood loss, around the time of World War I,” said Dr. Richard L. Gamelli, principal investigator, chair of the Department of Surgery and professor of trauma surgery, Loyola University Chicago Stritch School of Medicine. Currently, patients can only receive blood in a hospital and that means a trauma victim may need to wait up to an hour for a transfusion following transport to the hospital and being typed and cross-matched. “Saline, the current standard of care, helps us restore a patient’s blood pressure but does not deliver oxygen, a critical nutrient to prevent organ damage in the brain, heart, lungs, liver and kidneys,” Gamelli explained. “Carrying blood in an ambulance isn’t practical because it needs to be refrigerated, has a short shelf life and needs to be typed and cross-matched to the specific patient. In contrast, the blood substitute carries oxygen, has a long shelf life and is compatible with all blood types,” said Gamelli, who also is chief of Loyola’s Burn Center and director of Loyola’s Burn and Shock Trauma Institute.
In order to receive approval for the field component of this clinical trial, U.S. Food and Drug Administration regulations and Loyola’s IRB required evidence that broad public notification has been made to ensure members of the public have an opportunity to share their concerns. In addition to the community outreach efforts, members of the public had the opportunity to provide feedback on the Web, via e-mail, through a dedicated phone line, and in-person at eight community meetings.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
