which can run for years without needing to be wound manually. The new system works like this:
then the cable can get taut and fracture, which is really bad news . So we wanted to understand what was underlying those patterns.
which, when wound on a spool, retains a certain amount of curve as it unwound.
However, these devices, often created with nondegradable elastic polymers, bear an inherent risk of intestinal obstruction as a result of accidental fracture or migration.
as there is a greater risk for fracture if a device is too large or too complex.
Most commercial sunblocks are good at preventing sunburn, but they can go below the skin surface
the researchers tested their sunblock against direct ultraviolet rays and their ability to cause sunburn.
the researchersformulation protected equally well against sunburn. They also looked at an indirect and much less studied effect of UV LIGHT.
but applying these chemicals to the surface of wounds has its limits. To best stem blood loss, those chemicals need to be able to find their way deep into a wound.
There may now be a solution, however, and it comes in the unlikely form of fizz, reports Wired.
propelling them deep into a wound as they pop. The new concoction is composed of powdered marble, tranexamic acid
Water from the blood is the catalysis that sets it fizzing. f you can get the particles in the general area of the wound,
all the way to the damaged internal blood vessels feeding the wound. By clotting so deep into the lesion, the clot was shown to be more stable.
Right now the fizzing agent is a bit messy. While chemicals do get deeper into the wound,
they pop off in every other direction too. Eventually researchers hope to make the delivery process more efficient,

#Brain Friendly Interface Could Change the Way People with Spinal cord Injuries Lead Their Lives Recent research published in the journal Microsystems
and spinal cord injury lead their lives. Instead of using neural prosthetic deviceshich suffer from immune-system rejection
helping people living with limb loss and spinal cord injury become more independent. However not only do neural prosthetic devices suffer from immune-system rejection,
it can be difficult to determine precisely where lesions and growths are, because of mismatches between imaging speed and peristalsis,
If the rods and cones that make up the photoreceptors of the eye fail because of injury or illness,
Remote-controlled Eradication of Astrogliosis in Spinal cord Injury via Electromagnetically-induced Dexamethasone Release from"Smart"Nanowireswen Gao and Richard Borgenswe describe a system to deliver drugs to selected tissues continuously,
and deposited onto a spinal cord lesion in Glial fibrillary acidic protein-luc Transgenic mices (GFAP-luc mice). Overexpression of GFAP is an indicator of astrogliosis/neuroinflammation in CNS injury.
The corticosteroid DEX, a powerful ameliorator of inflammation, was released from the polymer by external application of an Electromagnetic field for 2 hours/day for a week.
"This tool allows us to apply drugs as needed directly to the site of injury, which could have broad medical applications,
but it is our hope that this could one day be used to deliver drugs directly to spinal cord injuries, ulcerations, deep bone injuries or tumors,
"The team tested the drug-delivery system in mice with compression injuries to their spinal cords
and transported a patch of the nanowire carpet on water droplets that were used used to deliver it to the site of injury.
The nanowire patches adhere to the site of injury through surface tension Gao said. The magnitude and wave form of the electromagnetic field must be tuned to obtain the optimum release of the drug,
GFAP is expressed in cells called astrocytes that gather in high numbers at central nervous system injuries. Astrocytes are a part of the inflammatory process and form a scar tissue,
A 1-2 millimeter patch of the nanowires doped with dexamethasone was placed onto spinal cord lesions that had been exposed surgically,
The lesions were closed then and an electromagnetic field was applied for two hours a day for one week.
