RELEASE OF VASOPRESSIN BY ENKEPHALIN [PDF]
British Journal of Pharmacology, 1978 Leu‐enkephalin, its stable analogue [D‐Ala2‐D‐Leu5]‐enkephalin and the C‐fragment of lipotropin (β endorphin) injected intravenously in the rat produced anti‐diuretic responses which were inhibited reversibly by naloxone. It was shown for Leu‐enkephalin that injection into the cerebral ventricles was at least ten times more effective than intravenous ...

A Comparative Study of MALDI MSI Versus DESI MSI Applied to Questioned Document Examination
Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.ABSTRACT Rationale In forensic investigations, questioned document examination (QDE) provides critical information for document authentication and the detection of forgeries. Conventional QDE approaches often require separate analyses of inks and of any potential fingerprints.

Functionalization of Peptides via Radical Arylation
ChemBioChem, Volume 27, Issue 19, 14 October 2026.Radical chemistry has only rarely been applied to peptide functionalization. This short review highlights radical arylation as an attractive approach to access functionalized peptides under mild, biocompatible conditions without protecting groups.

Enkephalin-dopamine interactions in behavioral arousal
, 1979 1. 1. Central injection of a long lasting enkephalin analog (D-Ala2-leuo-enkephalin-amide) produced a syndrome of stereotyped motor activity.2. 2. This activation syndrome was significantly reduced by two dopamine (DA) blockers (pimozide, fluspirilene ...

Frontiers in Neuroanatomy, 2011 Dopaminergic signaling within the basal ganglia has classically been thought to occur within two distinct neuronal pathways; the direct striatonigral pathway which contains the dopamine D1 receptor and the neuropeptides dynorphin and substance P, and the

Chemoselective Metabolomics via a Modular Reactivity‐Encoding Platform
Advanced Science, Volume 13, Issue 56, 9 October 2026.Conventional LC–MS underrepresents numerous metabolites due to heterogeneous ionization efficiencies and matrix interference. Here, we introduce a modular reactivity‐encoding platform (MREP) comprising four alkyne‐tagged probes that selectively derivatize key functional groups, followed by unified click‐chemistry capture to eliminate matrix components ...

Cancer‐Associated BCL‐2 Mutants Reveal Mechanisms Towards Venetoclax Resistance
Advanced Science, Volume 13, Issue 57, 14 October 2026.Venetoclax (VEN) resistance in chronic lymphocytic leukemia arises from diverse BCL2 mutations. We map mechanisms contributing to VEN resistance across common BCL‐2 variants. G101V and D103Y reduce drug binding and increase sequestration of pro‐apoptotic proteins. V156D blocks VEN allosterically.
