Cerebrospinal Fluid Proenkephalin Predicts Striatal Atrophy Decades before Clinical Motor Diagnosis in Huntington's Disease

Movement Disorders, EarlyView.
Abstract Background Huntington's disease (HD) is characterized by early, selective, progressive vulnerability of striatal medium spiny neurons (MSNs). Proenkephalin (PENK), a precursor of opioid peptides abundantly expressed in MSNs, is a promising biomarker of striatal integrity, but region‐specific associations and its potential for early‐stage ...

Electroacupuncture attenuates retinal ischemia/reperfusion injury by protecting the outer blood-retina barrier via enkephalins activate delta opioid receptor

World Journal of Acupuncture - Moxibustion
Objectives: Retinal ischemia-reperfusion (RIR) injury results in irreversible visual impairments. The disruption of the outer blood-retinal barrier (OBRB) is a major ocular pathogenic process that RIR injury affects.

Design of Experiments (DoE)‐Optimized Polymeric Oxytocin Nanoparticles for Enhanced Nose‐to‐Brain Delivery

Small, EarlyView.
Intranasal (IN) delivery of PEGylated PLGA nanoparticles (NPs) loaded with oxytocin (OT) (OT‐NP‐PEG) is investigated as a strategy to enhance OT transport to the brain for treating autism and other neuropsychiatric disorders. The optimized NP formulation demonstrates appropriate physicochemical characteristics, improved stability, and enhanced mucosal ...

Molecular basis of domain‐specific angiotensin I‐converting enzyme inhibition by the antihypertensive drugs enalaprilat, ramiprilat, trandolaprilat, quinaprilat and perindoprilat

The FEBS Journal, EarlyView.
Inhibition of angiotensin I‐converting enzyme is an effective strategy for the treatment of hypertension. However, the clinically available ACE inhibitors cause side effects due to nonselective inhibition of the two catalytic domains of ACE (nACE and cACE).

Growth Hormone (GH)-Releasing Peptide Stimulation of GH Release from Human Somatotroph Adenoma Cells: Interaction with GH-Releasing Hormone, Thyrotropin- Releasing Hormone, and Octreotide. [PDF]

, 1994
The synthetic hexapeptide GH-releasing peptide (GHRP; His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) specifically stimulates GH secretion in humans in vivo and in animals in vitro and in vivo via a still unknown receptor and mechanism.

Further Insights Into Anticholinergic Action Informed by Japanese Anticholinergic Risk Scale

Geriatrics &Gerontology International, EarlyView.
ABSTRACT The increased anticholinergic burden caused by medications in older adults is one of the adverse drug reactions of particular concern, as it can exacerbate the onset of geriatric syndromes or induce cognitive dysfunction, and is also related to the issue of polypharmacy.

Interactions of the opioid and cannabinoid systems in reward: Insights from knockout studies

Frontiers in Pharmacology, 2015
The opioid system consists of three receptors, mu, delta, and kappa, which are activated by endogenous opioid peptides (enkephalins, endorphins and dynorphins). The endogenous cannabinoid system comprises lipid neuromodulators (endocannabinoids), enzymes

Effects of Electroacupuncture at ST36 on Visceral Pain and Inflammatory Markers in IBS Rats

Neurogastroenterology &Motility, EarlyView.
Electroacupuncture (EA) at ST36 significantly reduced visceral pain and colonic inflammation in IBS model rats. EA increased pain thresholds, lowered AWR scores, and downregulated key inflammatory mediators (IL‐1β, IL‐6, TNF‐α, TRPV1, NF‐κB). These findings highlight ST36‐targeted EA as a promising therapeutic strategy for IBS visceral hypersensitivity
