Effect of the potassium channel opener WAY‐133537 on the overactive bladder of spinalized rats
Bibliographic record
Abstract
AIMS: To test the efficacy of WAY-133537 for the treatment of overactive bladder (OAB) in a chronic paraplegic rat model. MATERIALS AND METHODS: Forty-eight female Sprague-Dawley rats were used in this study. Six animals served as normal controls (without spinal cord transaction (ST)), while 42 rats underwent ST at the 10th thoracic vertebra. Two weeks after ST, cystometrogram (CMG) was performed in six randomly chosen animals to ensure the development of neurogenic detrusor overactivity. The remaining 36 rats were divided into three equal groups, 12 received the vehicle as "paraplegic controls," 12 received WAY-133537 0.3 mg/kg, and 12 received WAY-133537 3 mg/kg. Each "paraplegic control" and treatment group was further divided into two sub-groups (n = 6), with CMG at 3 and 4 weeks after ST, respectively. RESULTS: Two weeks after ST, all "vehicle control" rats developed detrusor overactivity with a mean frequency of 0.96 and 1.48 contractions/min and amplitude of 22.96 and 31.22 cm H(2)O with 1- and 2-week treatment, respectively. Neurogenic detrusor overactivity disappeared from 50% of rats that received WAY-133537 0.3 mg/kg for 1 week, and frequency decreased to 0.41 contractions/min. After 2 weeks of treatment, detrusor overactivity vanished from 67% of the animals with even further reduction in the frequency of detrusor overactivity (0.22 contractions/min, P < 0.01). In rats that received 3 mg/kg of the drug for 1 week, detrusor overactivity disappeared from only one animal with a non-significant decline in frequency. Fifty percent of rats given WAY-133537 at the dose of 3 mg/kg/day for 2 weeks manifested no detrusor overactivity. CONCLUSIONS: WAY-133537 shows efficacy in increasing bladder capacity and reducing the frequency of spontaneous bladder contractions after ST in rats without decreasing voiding pressure.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
