Protein unfolding key to understanding blood clot mechanics

Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers -- a blood clot -- that stems the loss of blood at an injury site while remaining pliable and flexible. On the other hand, fibrin provides a scaffold for thrombi, clots that block blood vessels and cause tissue damage, leading to myocardial infarction, ischemic stroke, and other cardiovascular diseases. How does fibrin manage to be so strong and yet so extensible under the stresses of healing and blood flow?

Tips to avoid heat stroke

The first sign of dangerous heat stroke can be just that – no sweat. As the temperature rises, your body’s natural cooling mechanism, sweat (or more kindly, perspiration), evaporates and helps to cool your body. But on those hot, humid cut-the-air-with-a knife days, evaporation is slowed and your body may not be able to keep itself cool.

The condition, which is associated with aging and involves progressive functional decline, can cause heaviness, tightness, cramping or sharp pain in the calf muscle. Symptoms typically disappear with rest and return when walking resumes.

Insurance agents look into the future and see uncertainty and "opportunity"

For the tens of thousands of individual insurance agents nationwide, the idea of a health system overhaul hits close to home – and work.

For example, there could be requirements that all individuals have coverage, that employers provide insurance for their workers and that insurers cover anyone - regardless of preexisting conditions. In addition, there could be a government-run public plan that might compete with insurance companies.
