Content Validation of an Emergency Department Skin Risk Assessment Instrument.

Pressure injuries (PIs) are an important quality and patient safety metric for health care organizations. PI monitoring and treatment are often overlooked in the emergency department (ED). Emergency care professionals must be proactive about PI early identification and prevention strategies.

Dynamic regulation and requirement for ribosomal RNA transcription during mammalian development.

Ribosomal RNA (rRNA) transcription by RNA polymerase I (Pol I) is a critical rate-limiting step in ribosome biogenesis, which is essential for cell survival. Despite its global function, disruptions in ribosome biogenesis cause tissue-specific birth defects called ribosomopathies, which frequently affect craniofacial development. Here, we describe a cellular and molecular mechanism underlying the susceptibility of craniofacial development to disruptions in Pol I transcription.

Gadd45γ and Map3k4 interactions regulate mouse testis determination via p38 MAPK-mediated control of Sry expression.

Loss of the kinase MAP3K4 causes mouse embryonic gonadal sex reversal due to reduced expression of the testis-determining gene, Sry. However, because of widespread expression of MAP3K4, the cellular basis of this misregulation was unclear. Here, we show that mice lacking Gadd45γ also exhibit XY gonadal sex reversal caused by disruption to Sry expression.
