Markers for internal neoplasia in the horse

Veterinary Medicine and Science, Volume 9, Issue 1, Page 132-143, January 2023., 2023
The measurement of tumour markers in horses should be performed only in risk groups or in patients with suspicious clinical/laboratory findings (paraneoplastic syndromes). The results should be interpreted with caution as many factors (e.g., young age, pregnancy and inflammation) affect their concentration or activity.

Inverted Variant of Takotsubo Syndrome Caused by Inhaled Adrenergic Beta-2 Agonists

European Journal of Case Reports in Internal Medicine, 2018
Takotsubo syndrome (TS) is an acute and reversible clinical syndrome characterized by transient hypokinesis of the left ventricular (LV) apex. Variant forms of LV dysfunction have been reported, including inverted Takotsubo syndrome (ITS), which ...

Models of the cardiac L‐type calcium current: A quantitative review

WIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023
We discuss 73 published models of mammalian ICaL and find differences in gating kinetics, electrochemical driving force, and sensitivity to internal calcium concentrations, leading to considerable variability in their predictions. Abstract The L‐type calcium current (ICaL) plays a critical role in cardiac electrophysiology, and models of ICaL are vital

Fusion of the β2‐adrenergic receptor with either Gαs or βarrestin‐2 produces constitutive signaling by each pathway and induces gain‐of‐function in BEAS‐2B cells

FASEB BioAdvances, Volume 4, Issue 12, Page 758-774, December 2022., 2022
Abstract The β2AR is a prototypical G protein‐coupled receptor (GPCR) known to orchestrate different cellular responses by the stimulation of specific signaling pathways. The best‐established signaling pathways for the β2AR are the canonical Gs pathway and the alternative β arrestin 2 (βarr2) pathway.

Beta-adrenergic agonists as additive in beef cattle

Boletim de Indústria Animal, 2014
The agonists receptor beta-adrenergic (β-AA) are present in virtually all types of mammalian cells and are stimulated by catecholamines (epinephrine and norepinephrine) produced by the organism itself.

Trafficking of β2-adrenergic receptors: insulin and β-agonists regulate internalization by distinct cytoskeletal pathways [PDF]

Journal of Cell Science, 2004
Insulin and β-adrenergic agonists stimulate a rapid phosphorylation and sequestration of the β2-adrenergic receptors (β2ARs). Although the expectation was that a common pathway would be involved in the trafficking of the β2AR in response to either hormone, studies reported herein show the existence of unique cytoskeletal requirements for ...

β‐Agonist‐induced constitutive β₂‐adrenergic receptor activity in bovine tracheal smooth muscle [PDF]

British Journal of Pharmacology, 2000
According to the two state receptor model, the β2‐adrenergic receptor (β2‐AR) isomerizes between an inactive state and a constitutively active state, which couples to the stimulatory G‐protein in the absence of agonist. In bovine tracheal smooth muscle (BTSM), we investigated the effect of short and long term β2‐AR activation by fenoterol on ...
