The biopsychology of maternal behavior in nonhuman mammals [PDF]

open access: yes, 1990
The term “maternal behavior,” when applied to nonhuman mammals, includes the behaviors exhibited in preparation for the arrival of newborn, in the care and protection of the newly arrived young, and in the weaning of those young, and represents a complex

Easier, Safer, and Greener: Unlocking the Power of Solid Reagents in Organic Reactions by Mechanochemistry

open access: yesChemistryEurope, EarlyView.
This review highlights the powerful synergy between mechanochemistry and solid reagents to replace hazardous substances traditionally used in organic synthesis. Such an approach offers a safer and more sustainable pathway for conducting organic reactions, with potential benefits in both reactivity and selectivity. The use of solid bases, acids, and gas

M3 muscarinic acetylcholine receptor facilitates the endocytosis of mu opioid receptor mediated by morphine independently of the formation of heteromeric complexes [PDF]

open access: yes, 2017
Morphine inefficiency to induce the internalization of mu opioid (MOP) receptors observed in numerous experimental models constitutes a paradigm of G-protein coupled receptor (GPCR) functional selectivity.

Endogenous Opioid Activity in the Anterior Cingulate Cortex Is Required for Relief of Pain

open access: yesJournal of Neuroscience, 2015
Pain is aversive, and its relief elicits reward mediated by dopaminergic signaling in the nucleus accumbens (NAc), a part of the mesolimbic reward motivation pathway. How the reward pathway is engaged by pain-relieving treatments is not known. Endogenous

Recent applications of magnetic iron oxide nanoparticles for cerebral blood volume quantification in functional magnetic resonance imaging

open access: yesIbrain, EarlyView.
This study explores the recent advances in the use of iron oxide nanoparticles (IONPs) in functional MRI (fMRI) for studying brain functions, specifically cerebral blood volume (CBV) measurements. It covers fMRI techniques, magnetic nanoparticle synthesis, coating methods, and their applications in CBV imaging, in comparison to other contrast agents in
