The importance of longitudinal evaluation using DAT‐SPECT in organophosphate‐induced toxic parkinsonism

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.
We performed longitudinal evaluation using magnetic resonance imaging (MRI) and dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) in a case of organophosphate‐induced toxic parkinsonism. Fluid‐attenuated inversion recovery (FLAIR) images showed bilateral striatal hyperintensity in the acute phase, followed by reduction of ...

Pharmacologic MRI Brain Imaging Studies of Serotonin 5‐HT1 Receptor Agonists in Awake Mice

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Serotonin (5‐hydroxytryptamine, 5‐HT) type‐1 G protein‐coupled receptors are expressed throughout the central nervous system. 5‐HT1AR activation is the putative mechanism of approved drugs for generalized anxiety disorder and major depressive disorder and is being studied in the treatment of autism and neurological disorders.

Magnitude, Preventability, and Determinants of Adverse Drug Reactions Among Hospitalized Obstetric Patients in Ethiopia: A Prospective Observational Study

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Adverse drug reactions (ADRs) are an important and potentially preventable cause of morbidity among hospitalized obstetric patients, with implications for both maternal and fetal safety, yet evidence from low‐resource settings remains limited.

GRKs and arrestins: Nomenclature and functions in GPCR‐dependent and ‐independent signalling

British Journal of Pharmacology, Volume 183, Issue 11, Page 2619-2633, June 2026.
G protein‐coupled receptor (GPCR) kinases (GRKs) and arrestins play a critical role in the regulation of GPCR signalling. Historic names of mammalian GRKs were replaced by systematic ones in the 1990s; however, both kinds of names are currently in use for mammalian arrestins.
