All cells in an animal collectively ensure, moment-to-moment, the survival of the whole organism in the face of environmental stressors . Physiology seeks to elucidate the intricate network of interactions that sustain life, which often span multiple organs, cell types, and timescales, but a major challenge lies in the inability to simultaneously record time-varying cellular activity throughout the entire body. We developed WHOLISTIC, a method to image second-timescale, time-varying intracellular dynamics across cell-types of the vertebrate body.

Optimal neuraxial anesthesia for cesarean delivery requires a thorough understanding of patient, obstetrical, surgical, and anesthesia-related factors which can impact pain during and after cesarean delivery. While not all cesarean deliveries are the same from an obstetrical standpoint, not all anesthetics provide the same degree of anesthetic blockade and postcesarean analgesia; therefore, context is crucial to provide patients with a safe and pain-free experience. Communication between obstetrical and anesthesia teams is key to ensure that the anesthetic approach is tailored to the clinical scenario, particularly if emergency cesarean delivery is needed, and follows best practices for cesarean delivery anesthesia.

: Borderline Personality Disorder (BPD) involves emotional dysregulation, interpersonal instability and impulsivity. Although treatments have advanced, evaluating the latest innovations remains essential. This rapid review aimed to (1) identify and classify recent therapeutic innovations for BPD, (2) assess their effects on clinical and functional outcomes, and (3) highlight research gaps to inform future priorities.

With ketamine gaining attention as a therapeutic drug, oral administration offers an effective alternative to traditional parenteral routes. However, a significant gap remains in understanding its use via voluntary ingestion. This preliminary study aimed to explore the feasibility of oral ketamine self-administration in mice (), while investigating the effects of low concentrations on the brain, liver, and kidney.

Treatment-resistant depression (TRD) represents a major clinical challenge. Affecting about 30 % of major depressive disorder (MDD) patients, effective treatments for TRD are urgently needed. While depression research and antidepressant (AD) development have long centred on monoaminergic targets, research over the past 35 years has increasingly explored glutamatergic mechanisms.
