A small, external bioreactor holding human cells pumped out an anti-inflammatory protein to prevent organ damage and other complications in a rat with acute inflammation caused by bacterial products in a model of sepsis, according to a report from researchers at the University of Pittsburgh School of Medicine and the McGowan Institute for Regenerative Medicine. The findings were published today in the inaugural issue of Disruptive Science and Technology. Inflammation is a necessary...

The body's natural inflammatory response is an essential reaction to injury and infection. When acute inflammation escalates out of control, such as in sepsis, it causes nearly 10% of deaths in the U.S. and more than $17 billion in healthcare costs each year. A group of researchers have developed a groundbreaking biohybrid device that can control acute inflammation to prevent sepsis and other related life-threatening complications, as described in an article in the inaugural issue of...

Microglia are the first line defence of the brain and are constantly looking for infections to fight off. Overactive microglia can cause uncontrolled inflammation within the brain, which can in turn lead to neuronal damage. New research published in BioMed Central's open access journal Journal of Neuroinflammation shows that, honokiol (HNK) is able to down-regulate the production of pro-inflammatory cytokines and inflammatory enzymes in activated microglia via Klf4, a protein known to...

Researchers at the University of Copenhagen have documented a previously unknown biological mechanism in the brain's most important line of defense: the blood-brain barrier. Scientists now know that the barrier helps maintain a delicate balance of glutamate, a vital signal compound in the brain. The research results have just been published in the scientific journal GLIA. Glutamate is the most important activating transmitter substance in the brain. Vital in small amounts, it is toxic for...

The National Institute of Standards and Technology (NIST), in collaboration with the Centers for Disease Control and Prevention (CDC), has developed two new Standard Reference Materials (SRMs) for measurements of human exposure to environmental toxins. Used as a sort of chemical ruler to check the accuracy of tests and analytic procedures, the new reference materials replace and improve older versions, adding measures for emerging environmental contaminants such as perchlorate, a chemical...

Although the temperate climates of central Europe provide plentiful food in summer, finding enough to eat is much more problematic in winter. Many small mammals avoid the problem by hibernating but this survival strategy is generally not practiced by larger animals. With the exception of some bears, large mammals remain fully awake throughout the year, yet they too must reduce their metabolism to cope with the comparative scarcity of food. Red deer, for example, are known to lower their heart...

How Do Mosquitoes Keep Their Cool?

No one likes being bitten by whining mosquitoes, but have you ever considered what the experience is like for them as their cold-blooded bodies fill with our warm blood? Now researchers reporting online on December 15 in Current Biology, a Cell Press publication, have uncovered the mosquitoes' secret to avoiding heat stress: they give up cooling droplets of their hard-won meals. The study shows for the first time that blood-feeding insects are capable of controlling their body temperature,...
