Percolation on interdependent networks with a fraction of antagonistic interactions [PDF]

open access: yesJournal of Statistical Physics, 152,1069 (2013), 2013
Recently, the percolation transition has been characterized on interacting networks both in presence of interdependent and antagonistic interactions. Here we characterize the phase diagram of the percolation transition in two Poisson interdependent networks with a percentage q of antagonistic nodes. We show that this system can present a bistability of

Histamine induced high mobility group box-1 release from vascular endothelial cells through H1 receptor

open access: yesFrontiers in Immunology, 2022
BackgroundSystemic allergic reaction is characterized by vasodilation and vascular leakage, which causes a rapid, precipitous and sustained decrease in arterial blood pressure with a concomitant decrease of cardiac output.

Studies on Histamine H2-Receptor Antagonists by Using Density Functional Theory [PDF]

open access: yes, 2020
Density functional theory (DFT) is a quantum mechanical approach used to investigate the electronic structure (principally the ground state) of many-body systems, in particular atoms, molecules, and the condensed phases.

Histamine and its Effects Mediated via H3 Receptor – Potential Clinical Applications of H3 Antagonists

open access: yesActa Medica Martiniana, 2013
Histamine is one of the most important biogenic amines and it mediates numbers of physiological processes. It is also involved in majority of inflammatory diseases via its receptors H1, H2, H3 and H4.

Pore-Scale Visualization of Hydrogen Storage in a Sandstone at Subsurface Pressure and Temperature Conditions: Trapping, Dissolution and Wettability [PDF]

open access: yes, 2022
The global commitment to achieve net-zero has led to increasing investment towards the production and usage of green hydrogen (H2).However, the massive quantity needed to match future demand will require new storage facilities. Underground storage of H2 is a potentially viable solution, but poses unique challenges due to the distinctive physical and ...

Influence of mirtazapine on salivary cortisol in depressed patients [PDF]

open access: yes, 2003
Unlike other antidepressants, mirtazapine does not inhibit the reuptake of norepinephrine or serotonin but acts as an antagonist at presynaptic alpha(2)-receptors, at postsynaptic 5-HT2 and 5-HT3 receptors, and at histaminergic H1 receptors. Furthermore,

The Effect of H2 Receptor Antagonist in Acid Inhibition and Its Clinical Efficacy

open access: yesThe Korean Journal of Gastroenterology, 2017
The first histamine H2 receptor antagonists (H2RAs) were developed in the early 1970s. They played a dominant role in treating peptic ulcer disease and gastroesophageal reflux disease (GERD).
