A Mayo Clinic research team is focusing on a hormone previously identified in the venom of the green mamba snake for the role it may play in a dangerous blood vessel narrowing in stroke patients that can lead to a second stroke, reduced blood flow and brain damage.
Called “cerebral vasospasm,” this common complication of stroke occurs in approximately one-third of patients who experience a ruptured brain blood vessel. Its cause is not known. By discovering a possible role for this hormone, Mayo Clinic researchers are establishing the conceptual foundations for a new treatment for cerebral vasospasm. Their report occurs in the current issue of Neurosurgery.
In their pilot study, the Mayo Clinic researchers discovered that a specific pair of amino acids -- a “peptide” known as DNP -- was significantly elevated (29 percent) in aneurysm patients who went on to develop complications of cerebral vasospasm. Among the six patients in the study who were followed for seven days after their initial aneurysm ruptured, four patients showed evidence of cerebral vasospasm -- a much higher frequency than the 30 percent figure commonly cited. Of the four patients who had cerebral vasospasm, three -- 75 percent -- had increased DNP levels.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
