Sorafenib-loaded PAMAM dendrimer attenuates liver fibrosis and its complications in bile-duct-ligated rats
Bibliographic record
Abstract
We assessed the effect of sorafenib-loaded polyamidoamine (PAMAM) dendrimer on liver fibrosis induced by bile duct ligation (BDL). Male Wistar rats were divided into 9 groups: intact, sham, DMSO + BDL, BDL, sorafenib (30 mg/kg), sorafenib (60 mg/kg), PAMAM + BDL, sorafenib (30 mg/kg) + PAMAM + BDL, sorafenib (60 mg/kg) + PAMAM + BDL. BDL was induced and then rats were treated daily with sorafenib and (or) PAMAM for 4 weeks. Improvement of liver was detected via assessment of ascites formation, collagen deposition, liver blood flow, vascular endothelial growth factor level, and blood cells count. Sorafenib-loaded PAMAM dendrimer in both 30 and 60 mg/kg doses reduced ascites formation, reduced collagen deposition, and improved drug-induced hematological side effects of sorafenib alone in comparison with sorafenib-alone treatment. Sorafenib-loaded PAMAM dendrimer increased liver blood flow compared with sorafenib-received groups. Sorafenib-loaded PAMAM dendrimer reduced BDL-induced liver injury compared with sorafenib-received groups. Moreover, sorafenib-loaded PAMAM dendrimer decreased vascular endothelial growth factor level in serum and liver tissue in comparison with sorafenib-received groups. Sorafenib-loaded PAMAM dendrimer profoundly improved the therapeutic effects of sorafenib in BDL rats.

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.
