This study has examined the relationship between the effects of opioids on the internalization
of mu opioid receptors (MORs) and the morphology of dendritic spines. Several opioids (…

Although chronic treatment with morphine is known to alter the function and morphology of
excitatory synapses, the effects of other opioids on these synapses are not clear. Here we …

Chiral derivatives of two cyclohexylethyl halopyridyl thiourea compounds (HI-509 and HI-510),
two α -methyl benzyl halopyridyl compounds (HI-511 and HI-512), and a cyclohexyl ethyl …

Although synthetic opioid peptide analogs have been used extensively to study the functional
roles of opioid receptors, little is known about their in vivo disposition. Our goal was to …

The mu opioid receptor agonist Tyr-d-Arg-Phe-Lys-Amide (d-Arg 2 -Lys 4 -Dermorphin 1-4
amide=DALDA) was infused continuously for 2 h into sheep. The presence of DALDA in ovine …

Concentration changes of methionine enkephalin-like immjnoreactivity (ME-li) and β-endorphin-like
immunoreactivity (BE-li) in the rat pituitary following diffuse brain injury were studied. …

Mass spectrometry was used to determine the molecular mass of rat pituitary β‐endorphin 1–31
(BE rat, 1–31 The measured molecular mass (3435 ± 1 Da, n= 5) of endogenous BE rat, …

The anti-proliferative effects of a novel bromomethoxylated arylphosphate derivative of
zidovudine (compound DDE46, CAS 213982-96-8) were first examined in a zebra fish embryo …

Carboxypeptidase E (CPE) is involved with the biosynthesis of many neuropeptides, including
several whose genes are regulated by haloperidol treatments. In this study, we examined …

The review article deals with early and late oral and dental problems occurring after
intensive anticancer chemoand radiotherapy and hematopoietic stem cell transplantation (HSCT). …
