Systemic Assessment of Calcium and Phosphorus Level after Implantation of Porous Iron in Rats
Bibliographic record
Abstract
One of important aspects in bone healing process is physiological level of calcium (Ca), and phosphorus (P) that can be altered by implantation of biodegradable porous iron.Therefore, this study aims to investigate the concentration of Ca, P and Ca/P ratio in the peripheral blood during the implantation period up to 4 months.Forty adult male Sprague Dawley rats were used and divided into 3 groups receiving different pore size of iron implants (pore size 450, 580, 800μm) and one group of sham.The implants (5x2x0.5mm)were inserted into flat bone defects at latero-medial of femoral bone.Blood sample was taken from ventral tail artery before and after 4 month of implantation.Calcium and P concentrations in the blood were determined by BA-88A Semi-Auto Chemistry Analyzer.Results showed that concentration of Ca and P are slightly higher after implantation than before implantation, except for the 450µm group.The Ca/P ratio before and after implantation was increased in the sham group, and decreased in the 450 and 800µm groups.Concentration of Ca, P and Ca/P ratio insignificantly change between before and 4 months after surgery in some groups.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
