Postcolitis Alterations in Dose-Dependent Effects of 5-HT1A Agonist Buspirone on Nociceptive Activity of the Raphe Magnus and Dorsal Raphe Neurons in Rats.
Eur J Neurosci

Laboratory of Cortico-Visceral Physiology, Pavlov Institute of Physiology of the Russian Academy of Sciences, Saint Petersburg, Russia.
The serotonergic raphe magnus (RMg) and dorsal raphe (DR) nuclei are crucial pain-regulating structures, which nociceptive activity is shown to be altered in gut pathology, but the underlying neuroplastic changes remain unclear. Considering the importance of 5-HT1A receptors in modulating both pain and raphe neuronal activity, in this study, we aimed to determine whether 5-HT1A-dependent visceral and somatic nociceptive processing within the RMg and DR is modified in postcolitis conditions. In anaesthetised male Wistar rats, healthy control and recovered from TNBS-induced colitis, the microelectrode recordings of RMg and DR neuron responses to noxious colorectal distension (CRD) or tail squeezing (TS) were performed prior and after intravenous administration of 5-HT1A agonist, buspirone.

Objective: We aimed to investigate the effectiveness of buspirone as an adjunctive therapy for alleviating anxiety symptoms in patients with depressive disorders who are already taking antidepressants.
Methods: This was an open-label prospective multicenter non-interventional observational study conducted over 12 weeks. We enrolled 180 patients diagnosed with depressive disorders according to DSM-5 criteria and Hamilton Anxiety Rating Scale (HAMA) scores ≥ 18.
Biological characteristics, immune infiltration and drug prediction of PANoptosis related genes and possible regulatory mechanisms in inflammatory bowel disease.

PANoptosis is one of several modes of programmed cell death (PCD) and plays an important role in many inflammatory and immune diseases. The role of PANoptosis in inflammatory bowel disease (IBD) is currently unknown. Differentially expressed PANoptosis-related genes (DE-PRGs) were identified, and pathway enrichment analyses were performed.

The pupillary reflex is a complex physiological response involving both the eye and associated neural pathways. Relative afferent pupillary defects (RAPDs) can present due to various underlying pathologies, yet their occurrence in serotonin syndrome has been rarely documented. This report details the case of a 21-year-old non-binary individual with a history of bipolar disorder who presented to the emergency department following a polypharmacy overdose, including significant ingestion of sertraline, aripiprazole, and buspirone.

Background/aims: Buspirone shows promise in treating disorders of gut-brain interaction (DGBIs), particularly functional dyspepsia. However, findings have been mixed.
Methods: We systematically searched for prospective studies testing buspirone for any upper gastrointestinal DGBI in 4 databases (Cochrane, PubMed, Scopus, and PsycInfo).
