The study demonstrates that an average image of an organ along with its variations can be obtained for the purposes of comparing individual cases and differentiating healthy forms from pathologies.

These waves occur even in small storms, which are quite common in the Norwegian Sea.

According to the researchers, they suggest that patients treated with cortisone in some forms should be informed of the risks and advised to refrain from alcohol and smoking.

Researchers now show that mild maternal hypertension early in pregnancy actually benefits the fetus, but that late pregnancy hypertension has negative health consequences for the child.

The animal study shows that radiation predictably alters levels of certain molecules in the blood. If verified in human subjects, the findings could lead to new methods for rapidly identifying people at risk for acute radiation syndrome after occupational exposures or nuclear reactor accidents, and they might help doctors plan radiation therapy for patients.

Their work shows that workers have a more active transcriptome than queens. This suggests that in these simple societies, workers may be the 'jack-of-all-trades' in the colony - transcriptionally speaking - leaving the queen with a somewhat restricted repertoire.

The protein, fascin-1, is involved in bundling together the actin filaments which form the internal scaffolding of a cell and are involved in cell movement.

The Solitaire Flow Restoration Device and the Trevo device, approved by Food and Drug Administration (FDA) in 2012 to treat stroke caused by the sudden obstruction of a brain blood vessel (acute ischemic stroke) showed improved results over a previous standard and first generation clot-removal device in clinical trials.
