Taurine and pioglitazone attenuate diabetes-induced testicular damage by abrogation of oxidative stress and up-regulation of the pituitary–gonadal axis
Bibliographic record
Abstract
Chronic hyperglycemia is associated with impairment of testicular function. The current study aimed to investigate the protective effects and the possible mechanisms of taurine and pioglitazone against diabetes-induced testicular dysfunction in rats. Diabetes was induced by streptozotocin injection. Both normal and diabetic rats received taurine (100 mg/kg) or pioglitazone (10 mg/kg) orally and daily for 6 weeks. Diabetic rats showed a significant (P < 0.001) increase in glycosylated hemoglobin, glucose, homeostasis model of insulin resistance, and pro-inflammatory cytokines. Serum insulin, testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were significantly (P < 0.001) decreased in diabetic rats. Taurine and pioglitazone alleviated hyperglycemia, decreased pro-inflammatory cytokines, and increased circulating levels of insulin, testosterone, LH, and FSH. Gene and protein expression of LH and FSH receptors and cytochrome P450 17α-hydroxylase (CYP17) was significantly (P < 0.001) down-regulated in testes of diabetic rats, an effect which was significantly increased after administration of taurine and pioglitazone. In addition, taurine and pioglitazone significantly decreased lipid peroxidation and DNA damage, and enhanced activity of the antioxidant enzymes in testes of diabetic rats. In conclusion, taurine and pioglitazone exerted protective effects against diabetes-induced testicular damage through attenuation of hyperglycemia, inflammation, oxidative stress and DNA damage, and up-regulation of the pituitary/gonadal axis.

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.
