Abstract

fetched live from OpenAlex

Two new chitosan silver(I) complexes, [Ag(2CS)(H2O)(NO3)] and [Ag(2CS)(ahmp)(H2O)] (CS = chitosan, Hahmp = 4-amino-6-hydroxy-2-mercaptopyrimidine) were synthesized and characterized on the basis of elemental analysis, spectral (FT-IR and solid-state 13C-NMR), morphological (SEM, matrix analysis, XRD, and XRPE), and thermal measurements. Chitosan behaves as a neutral ligand, coordinates Ag(I) through half of amino nitrogen centers, with the pendant glucose amine hydroxy functionality playing no role in coordination, while 4-amino-6-hydroxy-2-mercaptopyrimidine functions as mononegative bidentate, chelating through the deprotonated cyclic nitrogen and thione sulfur atoms. [Ag(2CS)(ahmp)(H2O)] displays a significant potential bone regenerator in rat mandible. Forty male rats were divided into two groups: bone defect (control) and bone defect with [Ag(2CS)(ahmp)(H2O)] (treated). The bone defects were stained with hematoxylin and eosin, and Masson's trichrome for histological analysis. The treated group shows faster and well organized bone formation in the defect in comparison to the control group which shows little new bone trabeculae and wide marrow cavities.

Full frame distilled prediction

Teacher imitation

Not 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.
