Ketamine, a potent N-methyl-D-aspartate receptor (NMDAR) antagonist, is widely used for anesthesia and analgesia and, because of its rapid antidepressant effects, in psychiatry. Increasing evidence suggests that ketamine and its enantiomers-(R)-ketamine (arketamine) and (S)-ketamine (esketamine)-also modulate systemic immunity and provide organ protection, partly through interactions with the...
Depression constitutes a major global public health burden, with university students exhibiting a disproportionately high prevalence of depressive symptoms. Although Mindfulness-Based Stress Reduction (MBSR) has demonstrated efficacy in alleviating depressive symptomatology, its underlying neurobiological mechanisms remain incompletely understood. This randomized controlled trial investigated...
Resilience helps mitigate the negative impacts of stress and promotes effective adaptation in adverse situations. This study investigated the impact of immediate and standardized mindfulness meditation (MM) on the resilience of college students, aiming to offer adaptable MM practices for different stress scenarios. The blood pressure (BP) and heart rate variability (HRV) of 48 participants were...
Emergency endotracheal intubation in critically ill patients are dangerous procedures with a greater risk of severe hypotension The efficacy and safety of esketamine with sympathoexcitatory effects for rapid sequence induction in critically ill patients remain unclear. In this prospective double-blinded randomized controlled trial, adult patients were randomly assigned to receive either...
This systematic review investigates the impact of meditation on neural responses to pain, as measured by functional magnetic resonance imaging (fMRI). Up to March 2024, we conducted searches across four databases for human studies implementing fMRI to assess the efficacy of meditation for pain relief. Eighteen studies met the inclusion criteria. Our systematic review indicates that activation...
