Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Excited state dynamics in DNA double helices [PDF]

arXiv, 2006
Recent ultrafast experiments have implicated that intrachain base-stacking rather than base-pairing mediate the fate and transport of photoexcited species in DNA chains. Here use an $SU(2)\otimes SU(2)$ lattice model which incorporates both intrachain and interchain electronic interactions to study the quantum mechanical evolution of an initial ...

Adenosine and adenosine-5′-monophosphate ingestion ameliorates abnormal glucose metabolism in mice fed a high-fat diet

BMC Complementary and Alternative Medicine, 2018
Background We have previously reported that ingestion of adenosine (ADN) and adenosine-5′-monophosphate (AMP) improves abnormal glucose metabolism in the stroke-prone spontaneously hypertensive rat model of non-obesity-associated insulin resistance.

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

Study of Cyclic Adenosine Monophosphate Microdomains in Cells

, 2005
Cyclic adenosine monophosphate (cAMP) controls the physiological response to many diverse extracellular stimuli. To maintain signal specificity, cAMP-mediated signaling is finely tuned by means of a complex array of proteins that control the spatial and temporal dynamics of the second messenger within the cell.

Baicalin inhibited PANX-1/P2Y6 signaling pathway activation in porcine aortic vascular endothelial cells infected by Glaesserella parasuis

Heliyon
Glaesserella parasuis can induce endothelial barrier damage in piglets, although the mechanism by which this pathogen triggers inflammatory damage remains unclear. Baicalin possesses anti-inflammatory and anti-oxidant activities.

AMPc: una molécula clave en los eventos de regulación inmune y en el control de la replicación del VIH cAMP: A keymolecule in events of immune regulation and in the control of HIV replication

Infectio, 2012
El monofosfato de adenosina cíclico (AMPc) induce la activación de la proteína cinasa A, la cual regula negativamente la activación, la proliferación celular y la producción de IL-2, en células T.

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.

Frenkel Exciton Model of Ultrafast Excited State Dynamics in AT DNA Double Helices [PDF]

J. Photochem. and Photobiol. A 190, 328-334 (2007), 2006
Recent ultrafast experiments have implicated intrachain base-stacking rather than base-pairing as the crucial factor in determining the fate and transport of photoexcited species in DNA chains. An important issue that has emerged concerns whether or not a Frenkel excitons is sufficient one needs charge-transfer states to fully account for the dynamics.
