Standardizing the Dosage and Timing of Dexamethasone for Postoperative Nausea and Vomiting Prophylaxis at a Safety-Net Hospital System.

Background: A single dose of dexamethasone is routinely given during general anesthesia for postoperative nausea and vomiting (PONV) prophylaxis, although the exact dosage and timing of administration may vary between practitioners. The authors aimed to standardize the dosage and timing of this medication when given to adult patients undergoing general anesthesia for elective surgery.

Methods: Baseline data for 7,483 preintervention cases were analyzed.

Stress signaling boosts interferon-induced gene transcription in macrophages.

Promoters of antimicrobial genes function as logic boards, integrating signals of innate immune responses. One such set of genes is stimulated by interferon (IFN) signaling, and the expression of these genes [IFN-stimulated genes (ISGs)] can be further modulated by cell stress-induced pathways. Here, we investigated the global effect of stress-induced p38 mitogen-activated protein kinase (MAPK) signaling on the response of macrophages to IFN.

Genetic mapping of , a pupal lethal mutation in .

An EMS mutagenesis screen was conducted in to identify growth control mutants. The multi-institution Fly-CURE consortium phenotypically characterized the mutant using the system which displayed a mutant lethal phenotype with reduced head development, and darkened ocular tissue. Complementation mapping was conducted to identify the affected gene.
