Epilepsy, a neurological disorder causing recurring seizures, is often studied in zebrafish by exposing animals to pentylenetetrazol (PTZ), which induces clonic- and tonic-like behaviors. While adult zebrafish seizure-like behaviors are well characterized, manual assessment remains challenging due to its time-consuming nature, potential for human error/bias, and the risk of overlooking subtle behaviors. Aiming to circumvent these issues, we developed a machine learning model for automating the analysis of subtle abnormal and seizure-like behaviors in PTZ-exposed adult zebrafish.

The assessment of measurement uncertainty of an analytic method is a requirement for forensic toxicologists and drug chemists. There are two main methods for estimating measurement uncertainty: the bottom-up and the top-down approaches. The bottom-up approach has been suggested in current practice guides including 'Guide to the Expression of Uncertainty in Measurement (GUM)' published by ISO, and a guide to 'Quantifying Uncertainty in Analytical Measurement' published by EURACHEM.

Background: Posterior fossa syndrome (PFS), also known as cerebellar mutism syndrome, occurs in about 25% of pediatric patients undergoing resection of a posterior cranial fossa medulloblastoma. It is characterized primarily by mutism or reduced/impaired speech and may include variable symptoms such as motor dysfunction (apraxia, ataxia, hypotonia), supranuclear cranial nerve palsies, neurocognitive changes, and emotional lability. Long-term multidisciplinary rehabilitation is typically required, with recovery taking approximately six months, though many children experience long-term residual deficits.

Sesamol (SES) and linalool (LIN) are aromatic compounds that have neuroprotective effects. The main purpose of this study is to evaluate the anxiolytic activity of LIN and SES co-treatment on Swiss albino mice and analyze its possible mechanism through in silico study. In this sense, the mice were given the gamma-aminobutyric acid type A receptors (GABA) agonist diazepam (DZP; 3 mg/kg, p.

The aim of this retrospective clinical study was to compare the combinations of ketamine/diazepam (KD group) and tiletamine/zolazepam (TZ group) for the induction of general anaesthesia in horses undergoing elective surgery. The data from the clinical and the anaesthetic records of 138 horses from 2021 to 2023 were evaluated, and the horses were divided in two groups: KD ( = 60) and TZ ( = 72). The horses were premedicated with romifidine and methadone IV; anaesthesia was induced with ketamine/diazepam for the KD group and tiletamine/zolazepam for the TZ group and was maintained with isoflurane and a constant rate infusion of romifidine.
