Exploring the molecular origin of blood clot flexibility
...force. But "it wasn't known before that the coiled coil
region of the fibrinogen molecule would be the part to unfold under the stress induced by the atomic force microscope," notes Brown. Once the origins of the mechanical properties of clots are well understood, it may be possible to modulate those pr...

and a sacral anterior root stimulator (SARS) implant (used for bladder emptying) affects pressure and skin blood circulation under the ischial tuberosities (ITs) of participants with spinal cord injury (SCI). The ITs are the most common site for pres...
Old technology helps find new test for leg artery disease

in the MRI then took readings of the phosphocreatine level in the legs every 15 seconds for several minutes afterward. "If the blood flow is poor," Kramer explained, "PCr recovery is slow, because the muscle is not getting the energy sources it needs...
Combination of three new, high-powered MRI systems at PENN is a first in the US
...ed in and out of the scanner several times while a coil
is moved around. This makes it more comfortable for the patient and also significantly lessens the scan time. Nick Bryan, MD, PhD, Chair of Radiology at Penn, summarizes the importance of this new addition, "It can be frightening to go see a doctor, ...

...ly to coronary artery stent placement or placing a coil
for an aneurysm. The surgeon snakes a catheter through the femoral artery and into the blood vessel in question. With the aid of X-rays, the surgeon navigates the stent device into the cerebral circulation to the precise location of the narrowing and...
Yale expands research using magnetic stimulation for schizophrenia
...ersons are awake by positioning an electromagnetic coil
on the scalp. "It appears that stimulating populations of neurons once per second with TMS over many minutes modestly reduces the capacity of these neurons to activate each other," Hoffman said. "As a result, neural populations as a whole become les...

is placed on the scalp, and a brief electrical current is passed through the coil, creating a magnetic pulse that stimulates the outer part of the brain, called the cortex. The study involved eight people, ages 35 to 63, who had a stroke within the l...
