The neural mechanisms underlying burst suppression during anaesthesia remain poorly understood. A recent study in the British Journal of Anaesthesia used calcium imaging to examine neuronal activity driving burst suppression in both cortical and subcortical structures. The results reveal diverse involvement of cortical excitatory neurones in burst suppression, while distinct interneurone subtypes play varied roles. Parvalbumin neurones in particular are key in modulating these rhythms. These insights will inform anaesthetic management of patients with neurological vulnerabilities.

We investigated the impact of short-term dietary nitrate supplementation on sympathetic neural responses to isometric exercise in postmenopausal women. Ten healthy women aged 64±2 (SD) years participated in this randomized, placebo-controlled, double-blind, crossover study. All participants underwent two-week beetroot juice (BRJ: 800 mg nitrate/day) and placebo (nitrate-depleted BRJ) interventions with ≥14 days of wash-out.

Neutrophil extracellular traps (NETs) are DNA-protein structures released during a form of programmed neutrophil death known as NETosis. While NETs have been implicated in both tumor inhibition and promotion, their functional role in cancer remains ambiguous. In this study, we compared the NET-forming capacity and functional effects of NETs derived from lung cancer (LC) patients and healthy donors (H).

Background: Remimazolam tosilate, a novel ultra-short-acting benzodiazepine, demonstrates promising safety profiles in clinical settings. While both remimazolam tosilate and etomidate provide hemodynamic stability during anesthesia induction, limited research has directly compared their effects on electroencephalogram (EEG) burst suppression (periods of transient brain wave silence), a potential predictor of adverse neurological outcomes. This study aims to compare the incidence rate of EEG burst suppression (ESR) with remimazolam tosilate versus etomidate by reviewing the drug regimens used by different anesthesiologists in clinical practice.

Background And Objectives: Guidelines for super-refractory status epilepticus (SRSE) evaluation, management, and prognostication are lacking. Characterization of practice patterns could identify trends and potential areas for future inquiry. We surveyed clinicians who manage SRSE to better understand practice approaches to SRSE evaluation, management, and prognostication.

Rice bacterial leaf streak (BLS) caused by Xanthomonas oryzae pv. oryzicola (Xoc) significantly reduces rice yield and quality. Traditional chemical control methods often have limited efficacy and raise environmental concerns, highlighting the need for safer and more effective alternatives.
