Temporary effects of circulating Amadori products on glomerular filtration properties in the normal mouse
Bibliographic record
Abstract
Previous studies have established a preferential glomerular filtration of glycated BSA (gBSA), as well as a facilitated filtration of BSA in the presence of gBSA. We intend to determine whether these modifications are permanent or transitory. gBSA was intravenously injected into anesthetized normal mice and maintained in circulation for 30 min, 1, 2, 24, and 48 h. Five minutes before death, FITC-BSA was injected. On immunocytochemical evaluations, increased glomerular filtration of FITC-BSA was found at all circulating time points. Changes at 24 and 48 h were less pronounced. Glomerular basement membrane (GBM)-to-lumen gBSA labeling ratios were similar at all time points suggesting no accumulation of gBSA in the GBM. Seventy percent of the gBSA was cleared from the circulation and the GBM after 24 h, and 95% after 48 h. This was confirmed in experiments with radiolabeled tracers. These results suggest that the alteration in GBM permeability to BSA in the normal mouse are due to the presence of gBSA and are gradually overcome along with its clearance from circulation. In early diabetes, increasing concentrations of circulating glycated proteins could be responsible for changes in glomerular permselectivity and probably for the alteration in glomerular filtration properties leading to diabetic nephropathy.

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.
