Kappa Opioid Regulation of Stress-Related Behavior [PDF]

open access: yes, 2010
Anxiety disorders affect roughly 40 million American adults in a given year. Those suffering from anxiety disorders often experience additional stress-linked illnesses, such as depression.

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

open access: yesJournal of Applied Polymer Science, EarlyView.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

Social trauma and the mu-opioid system in depression [PDF]

open access: yes, 2011
The overarching thesis under investigation is that the endogenous opioid system plays a key role in depression subsequent to traumatic childhood social experiences. This is suggested by the fact that animal work indicates that mu-opioids robustly mediate

Impact of parameter settings on the estimation of drug exposure with the individualized dispensing patterns method

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim To assess the impact of parameter settings when using the individualized dispensing patterns (IDP) method to estimate exposure duration from dispensing data. Methods We conducted a cohort study using a 2% representative sample of the French healthcare insurance database from 2013 to 2022.

The Role of Opioids on Motor Activity in Physio-pathological Conditions [PDF]

open access: yes, 2009
To date, four principal classes of opioid peptide receptors, μ (MOP), κ (KOP), δ (DOP) and ORL- 1 (NOP) have been identified and cloned. The experimental and clinical importance of this receptor family has been amply demonstrated in many diseases ...

Morphine Metabolism in Human Skin Microsomes [PDF]

open access: yes, 2012
For patients with severe skin wounds, topically applied morphine is an option to induce efficient analgesia due to the presence of opioid receptors in the skin.

Pharmacological assessment of thermal antinociception mediated by kappa opioid receptors in rhesus monkeys.

open access: yes, 1998
The possible existence of kappa opioid receptor subtypes has been reported by several laboratories based on radioligand binding experiments. However, there are some controversial issues remaining.

Rewiring nutrition: Chemical insights into the physiological and microbiological roles of food's microconstituents

open access: yesFood Biomacromolecules, EarlyView.
Bidirectional interactions between food‐derived sensory compounds, gut sensing and microbiota, host physiological feedback, and metabolite production within the food matrix collectively shape sensory perception, microbial dynamics, and metabolic health.

GTPγS-Autoradiography for Studies of Opioid Receptor Functionality

open access: yes, 2020
The opioid receptors have been an interesting target for the drug industry for decades. These receptors were pharmacologically characterized in the 1970s and several drugs and peptides have emerged over the years.

Differential stability of the crystallographic interfaces of mu- and kappa-opioid receptors. [PDF]

open access: yesPLoS ONE, 2014
The recent mu-opioid receptor (MOPr) and kappa-opioid receptor (KOPr) crystal structures have inspired hypotheses of physiologically relevant dimerization contacts, specifically: a closely packed interface involving transmembrane (TM) helices TM5 and TM6,
