Inflammatory molecules released by pollen trigger allergies

...tory molecules produced in the body in response to injury or infection. The authors now plan to assess whether cells from allergy-prone people are more sensitive to the effects of the pollen-derived compound than those from non-allergic individuals. A better understanding of these molecules and how they wor...

...otrecogin) in an attempt to minimize purpuric skin injury and to slow the inflammatory cascade before irreparable tissue injury occurs. In addition, because toxic shock syndrome is mediated by superantigens, it is possible that ...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

...in turn help the central nervous system respond to injury or infection. Because astrocytes also help to determine the number and connectivity of nervous system synapses early in life, especially the first week after birth in rats, they may be involved in the ability to learn and remember, possibly via some ...

New component of the 'brakes' on nerve regeneration found

... to regenerating spinal cord and brain cells after injury is the "braking" machinery in neurons that prevents regeneration. While peripheral nerves have no such machinery and can readily regenerate, central nervous system (CNS) neurons have their brakes firmly in place and locked. Now, two groups of scient...

Heart repair gets new muscle

Some organs in the human body deal with injury better than others. A flesh wound or muscle tear might hurt, but, assuming you are otherwise healthy, both will heal. The prognosis for a heart attack, on the other hand, is not so clear-cut. It has long been thought that cardiac cells (cardiomyocyt...

"We are, in essence, temporarily converting mice from warm-blooded to cold-blooded creatures, which is exactly the same thing that happens naturally when mammals hibernate," said lead i...

The lopsided brain: Attention bias is shared by humans and birds

...or some time that human patients who have suffered injury to the brain's right hemisphere can experience a much more severe bias in their spatial attention--spatial hemineglect--in which the entire left side of the visual world seems nonexistent as the brain performs spatial tasks.

Shark attack worries? Driving to the beach is more deadly
