Circadian clocks generate rhythms of arousal, but the underlying molecular and cellular mechanisms remain unclear. In Drosophila, the clock output molecule WIDE AWAKE (WAKE) labels rhythmic neural networks and cyclically regulates sleep and arousal. Here, we show, in a male mouse model, that mWAKE/ANKFN1 labels a subpopulation of dorsomedial hypothalamus (DMH) neurons involved in rhythmic arousal and acts in the DMH to reduce arousal at night.

Reasons for its wide pretreatment interpatient variability are not well understood.
Objective: To characterize clinicopathologic factors associated with TTMV HPV DNA.

Objectives: Hospital prices vary substantially for myringotomy with tympanostomy tube placement (M&T) and adenotonsillectomy (T&A). The Centers for Medicare and Medicaid Services recently implemented hospital price transparency requirements to help families make financially informed decisions about where to seek care. We sought to determine price availability and the extent of price variation for these procedures.

Study Design: Retrospective case series.

In January 2021, the Centers for Medicare & Medicaid Services began requiring hospitals to publish price transparency files listing all prices negotiated with payers. We performed a cross-sectional analysis of payer-negotiated prices for commonly performed outpatient otolaryngology surgery at all hospitals scored by the in otolaryngology. We compared prices among hospitals (across-center ratios) and among payers at the same hospital (within-center ratios).

In these investigations, physical, chemical, or electrolytic lesions of anatomical structures are applied, and the resulting behavioral or physiological responses assayed. An alternative approach is to focus on the expression pattern of a molecule whose function has been characterized and then use genetic intersectional methods to optogenetically or chemogenetically manipulate distinct circuits.
