Alcohol abuse can lead to severe psychological and physiological damage. Little is known, however, about the relative impact of a small, daily dose of alcohol (daily-moderate schedule) versus a large, once per week dose (weekly-binge schedule). In this study, we examined the effect of each of these schedules on behavioural measures of anxiety in zebrafish (Danio rerio). Adult wild-type zebrafish were administered either 0.2% ethanol on a daily-moderate schedule or 1.4% ethanol on a weekly-binge schedule for a period of 21 days, and then tested for scototaxis (preference for darkness) during withdrawal. Compared to a control group with no alcohol exposure, the daily-moderate group spent significantly more time on the light side of the arena (indicative of decreased anxiety) on day two of withdrawal, but not day 9 of withdrawal. The weekly-binge group was not significantly different from the control group on either day of withdrawal and showed no preference for either the light or dark zones. Our results indicate that even a small dose of alcohol on a daily basis can cause significant, though reversible, changes in behaviour.

Background: Remimazolam besylate, despite being widely used in various clinical settings, lacks evidence in cardiac anesthesia. This trial compared its efficacy with propofol in elective cardiac surgery.
Methods: A total of 320 adult patients undergoing elective cardiac surgery via cardiopulmonary bypass between December 2024 and March 2025 were randomized 1:1 to either propofol (1 mg/kg for induction and 1-1.

Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal cancer, primarily due to late-stage diagnosis and limited treatment options. Zinc homeostasis is markedly dysregulated in PDAC, and this dysregulation can be probed by administering a secretagogue to stimulate zinc secretion (SSZS) in the exocrine pancreas and imaging with a zinc sensitive magnetic resonance imaging (MRI) probe. This study demonstrated the potential of SSZS MRI for sensitive detection, monitoring treatment response, and assessing recurrence after treatment withdrawal in PDAC.

Data on daily life stress and autonomic physiology could help guide targeted interventions. We studied 302 individuals ≤ 61 years of age (129 women and 173 men) recently hospitalized for a myocardial infarction (MI).

This study adopted a three-dimensional "effect-dose-mechanism" evaluation system to screen the optimal regimen of Yuxuebi Tablets(YXB) combined with ibuprofen(IBU) for chronic musculoskeletal pain(CMP) intervention and elucidate its pharmacological mechanism, so as to provide a scientific basis for the clinical application of the regimen. The experiments were conducted using 8-week-old ICR mice, which were randomly divided into sham operation(sham) group, model(CFA) group, IBU group, YXB group, stasis paralysis tablets combined with ibuprofen low-dose group(IBU-L-YXB), stasis paralysis combined with ibuprofen high-dose group(IBU-H-YXB), stasis paralysis tablets combined with ibuprofen high-dose with ibuprofen discontinuation on the 10th day of administration(IBU-10-YXB), and stasis paralysis tablets combined with ibuprofen high-dose with ibuprofen halving on the 10th day of administration(IBU-1/2-YXB) group. An animal model was established using the CFA plantar injection method.
