Trigeminal neuralgia (TN) is a debilitating orofacial pain condition frequently complicated by anxiety and depression, forming a self-reinforcing pain-affect cycle with limited therapeutic options. A TN mouse model with anxiety-like behavior was established using partial infraorbital nerve transection (pIONT). Esketamine (ES) (5 or 10 mg/kg) was administered intraperitoneally from postoperative...
To explore the effect of esketamine (ES) pretreatment on necroptosis in mice with trigeminal neuralgia accompanied by anxiety-like behavior and its correlation with the RIP1/RIP3/MLKL signaling pathway. Thirty male C57BL/6J mice were randomized into five groups (n=6): Control, Sham, model group (PIONT), PIONT+NS, and PIONT+ES. Trigeminal neuralgia model was established by left infraorbital...
The increasing non-medical use of dextromethorphan (DM), particularly among adolescents, has raised concerns regarding its potential neurobiological consequences. However, the precise mechanisms underlying its neurotoxicity, particularly the involvement of the gut microbiota, remain unclear. A novel probiotic strain, Bacillus aerolatus CX253, has demonstrated the capacity to regulate gut...
Postpartum depression (PPD) is a common complication after childbirth, especially in primiparae. This trial sought to evaluate whether prophylactic administration of esketamine during the perinatal period could prevent PPD in primiparae without predisposition to prenatal depression. A prospective, double-blind, multicentre, randomised controlled trial. Three academic hospitals. Primiparae...
This article is grounded in the perspective of “harmony” and the tradition of “embodying the Dao” from classical Chinese philosophy and integrated with phenomenological body theory. It explores the intrinsic alignment between the traditional life cultivation theory of “imbibing the great harmony”1 and modern embodied cognition theory, supported by practical case studies. Through the practice of...
The components of mindfulness include awareness and acceptance. However, the effects of awareness and acceptance on psychological stress in adolescents remain controversial, and the underlying cognitive processes less attention. Therefore, this study aimed to examine their independent effects, and the relevant cognitive processes. A cross-sectional survey study (Study 1, N = 3304, Mage = 15.53...
Nursing students experience disproportionately high rates of mental health challenges, underscoring the urgent need for innovative, scalable interventions. Web-based mindfulness programs, and more recently, neurofeedback-enhanced approaches, present potentially promising avenues for addressing this critical issue. This study aimed to explore the effectiveness of the neurofeedback-assisted...
Esketamine (ESK), a new psychoactive substance known for its strong hallucinogenic effect, has been detected in surface water worldwide. The toxicity of ESK to fish at a certain environmental concentration remains unclear. In this study, zebrafish embryos and ZF4 cells were exposed to ESK (0, 0.12, 1.02, and 10.6 μg L-1, marked by SC, LC, MC, and HC, respectively) for 14 days post fertilization...
Prior meta-analyses have established the potential of intravenous ketamine in safeguarding against neurocognitive impairment, but the efficacy of intravenous esketamine for the prevention of perioperative neurocognitive disorders (PND) remains uncertain. The primary aim of this meta-analysis was to conduct a comprehensive evaluation of the effects of esketamine on PND in adult surgical patients...
Esketamine (ESK) is the S-enantiomer of ketamine racemate (a new psychoactive substance) that can result in illusions, and alter hearing, vision, and proprioception in human and mouse. Up to now, the neurotoxicity caused by ESK at environmental level in fish is still unclear. This work studied the effects of ESK on behaviors and transcriptions of genes in dopamine and GABA pathways in zebrafish...
Abstract: For a long time, the system of scientific methodology has been composed of logic, empirical (falsification), qualitative, quantitative and deterministic, and corresponding thinking tools. However, under the background of complexity science, the category of methodology should be changed, that is, on the basis of traditional methodology, non-classical logic, hierarchy, stereotype...
(R)-Ketamine (arketamine) may have utility as a rapidly acting antidepressant. While (R)-ketamine has lower potency than (R,S)-ketamine to inhibit NMDA receptors in vitro, the extent to which (R)-ketamine shares the NMDA receptor-mediated adverse effects of (R,S)-ketamine in vivo has not been fully characterised. Furthermore, (R)-ketamine is metabolised to (2R,6R)-hydroxynorketamine (HNK),...
The abuse of 3,4-methylenedioxymethamphetamine (MDMA), a psychedelic drug, can lead to a variety of disorders in neural system, including the death of retinal neural cells. MDMA at lower doses does not cause obvious cytotoxicity to photoreceptor cells, indicating potential indirect mechanisms which have not yet been elucidated. This study investigated the effect of MDMA at nontoxic...
This article reports a randomized controlled trial to investigate whether mindfulness training can successfully improve inner peace in participants with no known mental disorder. Fifty-seven participants were randomized to either mindfulness training (n = 29) or wait-list control (n = 28). The experience sampling method was used to measure the fleeting momentary experience of inner peace in...
