The Frequency and Clinical Significance of Sister Chromatid Exchange in the Lymphocyte of Gastric Cancer Patient Exposed to Hypoxia
Bibliographic record
Abstract
The frequency of sister chromatid exchange (SCE) in patients with gastric cancer is significantly higher than that in normal individuals; however, their characteristics have not been studied. In present study, we analyzed the correlation between the cytogenetic instability of gastric cancer patients’ peripheral lymphocytes with or without hypoxia and the characteristics of gastric cancer patients. The primary lymphocyte cultures obtained from blood samples of 40 healthy donors and 69 patients with gastric cancer were examined using SCE. The average of SCE frequency in gastric cancer was 5.91 ± 2.03/cell and the SCE phenotype was not associated with gender, tumor grade, Lauren classification, and H.pylori infection. Hypoxia increased the SCE frequency as compared with normoxia, in both the control and gastric cancer lymphocyte cultures (P < 0.001). The hypoxic effect in gastric cancer was not associated with gender, tumor grade, Lauren classification, and H.pylori infection. In conclusion, hypoxia did not facilitate an increase of SCE in the lymphocytes of the gastric cancer.

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.
