Resolution of Refractory Multifocal Atrial Tachycardia in Costello Syndrome Using Trametinib: A Case Supporting MEK Inhibitors as Targeted, Specific Antiarrhythmic

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Arrhythmias affect approximately half of patients with Costello syndrome (CS, OMIM # 218040), with non‐reentrant atrial tachycardia being the most common. This case describes an infant with Costello syndrome carrying the pathogenic HRAS c.34G>A (p.G12S) variant who developed early‐onset, drug‐refractory multifocal atrial tachycardia (MAT ...

Regulation of Neuromodulator Receptor Efficacy - Implications for Whole-Neuron and Synaptic Plasticity [PDF]

open access: yes, 2004
Membrane receptors for neuromodulators (NM) are highly regulated in their distribution and efficacy - a phenomenon which influences the individual cell's response to central signals of NM release.

Aging and aerobic fitness affect the contribution of noradrenergic sympathetic nerves to the rapid cutaneous vasodilator response to local heating [PDF]

open access: yes, 2011
Sedentary aging results in a diminished rapid cutaneous vasodilator response to local heating. We investigated whether this diminished response was due to altered contributions of noradrenergic sympathetic nerves; assessing 1) the age-related decline and,

Nano‐Gs Protein Peptidomimetics: Rational Design of Gα C‐Terminus‐Derived Peptides Mimicking Key Components of Gs‐β2AR Interactions

open access: yesAngewandte Chemie International Edition, EarlyView.
G protein‐coupled receptors (GPCRs) are major therapeutic targets. Modulating GPCR activity through intracellular sites is evolving. A structure‐ and computation‐assisted approach generated small G protein‐derived peptidomimetics targeting the intracellular binding crevice of the β2 adrenergic receptor mimicking features of the full G protein.

Single prazosin infusion in prelimbic cortex Fosters extinction of amphetamine-induced conditioned place preference [PDF]

open access: yes, 2017
Exposure to drug-associated cues to induce extinction is a useful strategy to contrast cue-induced drug seeking. Norepinephrine (NE) transmission in medial prefrontal cortex has a role in the acquisition and extinction of conditioned place preference ...

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

open access: yesThe Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.

Preponderance of alpha 2- over beta 1-adrenergic receptor sites in human fat cells is not predictive of the lipolytic effect of physiological catecholamines

open access: yesJournal of Lipid Research, 1983
Adrenergic control of human fat cell lipolysis is mediated by two kinds of receptor sites that are simultaneously stimulated by physiological amines. To establish a correlation between the binding characteristics of the receptor and biological functions,
