A Proposed Set of Metrics to Reduce Patient Safety Risk From Within the Anatomic Pathology Laboratory.

Background: Anatomic pathology laboratory workflow consists of 3 major specimen handling processes. Among the workflow are preanalytic, analytic, and postanalytic phases that contain multistep subprocesses with great impact on patient care. A worldwide representation of experts came together to create a system of metrics, as a basis for laboratories worldwide, to help them evaluate and improve specimen handling to reduce patient safety risk.

Inhibition of crystallin expression and induction of apoptosis by lens-specific E1A expression in transgenic mice.

Previous studies have shown that the adenovirus E1A oncoprotein can bind to and inactivate the retinoblastoma tumor suppressor protein (pRb) and the transcriptional coactivators CBP/p300. In this study, wild-type E1A12S or two deletion mutants (delN, which binds pRb but not CBP/p300; delCR2, which binds to CBP/p300 but not pRb) were linked to the lens-specific alphaA-crystallin promoter, and used to generate transgenic mice. Lens fiber cells expressing E1A12S or delCR2, both of which bind to CBP/p300, failed to upregulate beta-crystallin and gamma-crystallin expression.
