Background & Aims: Release of proinflammatory cytokines after traumatic brain injury (TBI) is a major cause of brain edema. Previous studies demonstrated that sex steroids decrease brain edema induced by TBI. In this study changes of brain cytokines after the administration of estrogen and progesterone 24 hours after TBI were evaluated. Materials and Methods: Female rats were divided into 7 gro...

An analog-to-digital converter for on-chip focal-plane image sensor applications. The analog-to-digital converter utilizes a single charge integrating amplifier in a charge balancing architecture to implement successive approximation analog-to-digital conversion. This design requires minimal chip area and has high speed and low power dissipation for operation in the 2-10 bit range. The inventio...
