Intermittent documentation of blood pressure values does not provide comprehensive evaluation of the hemodynamic response during continuous intravenous medication administration.

Blood pressure (BP) is a dynamic measure that is frequently discussed in static terms. There exist many limitations in current documentation systems whereby documented BP values may not be reflective of the dynamic variability of BP. This study used an observational, prospective, non-randomized study design to examine the variability in BP response during intravenous vasoactive medication administration in an intensive care unit setting.

Hypoxia inducible factor-dependent upregulation of Agrp in glomus type I cells of the carotid body.

Agouti-related peptide (AgRP) is a well-established potent orexigenic peptide primarily expressed in hypothalamic neurons. Nevertheless, the expression and functional significance of extrahypothalamic AgRP remain poorly understood. In this study, utilizing histological and molecular biology techniques, we have identified a significant expression of Agrp mRNA and AgRP peptide production in glomus type I cells within the mouse carotid body (CB).

Roles for Prlhr/GPR10 and Npffr2/GPR74 in feeding responses to PrRP.

Objective: Several groups of neurons in the NTS suppress food intake, including Prlh-expressing neurons (NTS cells). Not only does the artificial activation of NTS cells decrease feeding, but also the expression of Prlh (which encodes the neuropeptide PrRP) and neurotransmission by NTS neurons contributes to the restraint of food intake and body weight, especially in animals fed a high fat diet (HFD). We set out to determine roles for putative PrRP receptors in the response to NTS PrRP and exogenous PrRP-related peptides.

Quantitative pupillometry as a potential biomarker in early concussion assessment.

Background: There are limited objective methods when it comes to identifying and diagnosing concussion. Pupil assessment is performed routinely as a standard-of-care following traumatic brain injury (TBI). Unlike the highly subjective and limited reliability of pupil assessment using penlights and flashlights, Quantitative pupillometry (QP) is an established, valid, and reliable method of pupillary assessment.
