Transmural Autonomic Regulation of Cardiac Contractility at the Intact Heart Level

Frontiers in Physiology, 2019
The relationship between cardiac excitability and contractility depends on when Ca2+ influx occurs during the ventricular action potential (AP). In mammals, it is accepted that Ca2+ influx through the L-type Ca2+ channels occurs during AP phase 2 ...

Biased, Bitopic, Opioid–Adrenergic Tethered Compounds May Improve Specificity, Lower Dosage and Enhance Agonist or Antagonist Function with Reduced Risk of Tolerance and Addiction

Pharmaceuticals, 2022
This paper proposes the design of combination opioid–adrenergic tethered compounds to enhance efficacy and specificity, lower dosage, increase duration of activity, decrease side effects, and reduce risk of developing tolerance and/or addiction ...

Insights into the Dynamics and Binding Mechanisms of the Alkhumra Virus NS2B/NS3 Protease: A Molecular Dynamics Study

Advanced Theory and Simulations, EarlyView.
The ΔRMSF$\Delta {\rm RMSF}$ analysis reveals significant flexibility differences between free NS3 and the NS2B/NS3 complex, with notable deviations in specific regions. Key residues driving NS2B binding are identified, and the protonation state of catalytic serine affects oxyanion hole formation.

The protective effects of rutin on the liver, kidneys, and heart by counteracting organ toxicity caused by synthetic and natural compounds

Food Science &Nutrition, Volume 11, Issue 1, Page 39-56, January 2023., 2023
Rutin is a flavonoid present in many plant species. Because of its antioxidant, anti‐inflammatory, and anti‐apoptotic properties, rutin is of interest for its potential protective effects against toxic agents. Rutin has potential therapeutic effectiveness against several toxicants, and its beneficial effects are more than likely mediated by its ...

Synthesis and Characterization of Photoswitchable Covalent Ligands for the β2‐Adrenoceptor

Angewandte Chemie, EarlyView.
A structure‐based design of a covalent photoswitchable ligand for the β2‐adrenergic receptor, a therapeutically relevant GPCR, is described. This tool facilitates the modification of the intrinsic activity of the protein by light. Computational analysis of its mechanism of action suggests that the photoswitch takes place within the binding pocket ...

Acylated and unacylated ghrelin directly regulate ß-3 stimulated lipid turnover in rodent subcutaneous and visceral adipose tissue ex vivo but not in vivo

Adipocyte, 2019
Ghrelin has garnered interest as a gut-derived regulator of lipid metabolism, beyond its classical roles in driving appetite and growth hormone release.

Adrenergic Receptors

, 2017
This chapter will review the essential properties of adrenergic receptors in the physiology of cardiac function and in the pathology of cardiovascular disease. Following a systematic overview and a classification of adrenergic receptors, we will discuss the pathophysiological role of the sympathetic nervous system in several conditions including ...

Sensory Encoding Alternates With Hippocampal Ripples across Cycles of Forebrain Spiking Cascades

Advanced Science, EarlyView.
This study reveals widespread, coordinated brain activity during passive visual stimulation in mice. Sensory coding, phase‐locked with the periodic dynamics, shows an inverse relationship to hippocampal ripples. The results suggest that periodic brain activity spurs alteration between two distinct operational modes of brain, facilitating exteroceptive ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...
