Results suggest the fluid could increase survival in trauma patients and wounded soldiers
A novel resuscitation fluid derived from aloe vera that was developed by researchers at the University of Pittsburghs McGowan Institute for Regenerative Medicine has the potential to save the lives of patients with massive blood loss, according to results of an animal study published in the August edition of the medical journal Shock. The findings could have a significant impact on the treatment of hemorrhagic shock caused by both civilian and military trauma.
In a rodent model of hemorrhagic shock, animals that were given a very small amount of the fluid, an aloe vera-derived drag reducing polymer (DRP), had significantly longer survival time and increased systemic whole body oxygen consumption, even in the absence of resuscitation with blood or other fluids, compared to animals that did not receive DRP.
"We hope this fluid will offer a viable solution to a significant problem, both on and off the battlefield. Typically, hemorrhagic shock is treated by controlling ongoing bleeding and restoring blood volume by infusing a lactate solution and packed red blood cells. Soldiers wounded in combat often lose significant amounts of blood, and there is no practical way to replace the necessary amount of blood fast enough on the front lines. When this happens, there is inadequate perfusion of the organs which quickly leads to a cascade of life-threatening events," said senior author Mitchell P. Fink, M.D., professor and chair, department of critical care medicine and Watson Professor of Surgery at the University of Pittsburgh School of Medicine.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
