Abstract: A piezoelectric printhead includes a piezoelectric printing device, a manifold, a U-shaped flexible printed wiring element and an interconnection element. The piezoelectric printing device includes a piezoelectric plate and a substrate with at least one row of drop ejectors; an ink inlet port; signal lines leading to corresponding signal input pads; and ground traces leading to at least one ground return pad. The manifold is fluidically connected to the ink inlet port. The U-shaped flexible printed wiring element includes a device connection region and a pair of legs that extend from the device connection region. The pair of legs includes signal connection lines and at least one ground connection line. The interconnection element is disposed between the device connection region of the U-shaped flexible printing wiring element and a contact layer of the piezoelectric printing device that includes the signal input pads and the at least one ground return pad.

Abstract: Provided herein are methods, for reducing, preventing, mitigating and treating damage caused by radiation. The methods comprise delivering a compound, as described herein, to a patient in an amount and dosage regimen effective to prevent, mitigate or treat damage caused by radiation or to mitigate apoptosis. The compounds comprise glyburide or other sulfonylurea hypoglycemic compounds or potassium channel inhibitors.

Abstract: Provided herein are compositions and related methods useful for free radical scavenging, with particular selectivity for mitochondria. The compounds comprise a nitroxide-containing group attached to a mitochondria-targeting group. The compounds can be cross-linked into dimers without loss of activity. Also provided herein are methods, for preventing, mitigating and treating damage caused by radiation. The method comprises delivering a compound, as described herein, to a patient in an amount and dosage regimen effective to prevent, mitigate or treat damage caused by radiation.
