Abstract

fetched live from OpenAlex

OBJETIVO: Investigar o estresse oxidativo durante a regeneração hepática em ratos submetidos à hepatectomia (HP) e, ao mesmo tempo, avaliar a função hepática enquanto em regeneração. MÉTODO: 36 ratos Wistar machos jovens foram aleatoriamente distribuídos em dois grupos de 18 animais: submetidos somente à laparotomia (controle, Grupo G1) e parcialmente hepatectomizados (experimento, Grupo G2). Nos tempos 36h (T1), 168h (T2) e 336h (T3) pós-HP, GSH foi medida no plasma e no tecido hepático, enquanto Gli e BT foram aquilatados no sangue. A massa do fígado residual foi utilizada para estimar a evolução da regeneração hepática. RESULTADOS: Houve diferença estatisticamente significativa no crescimento dos lobos residuais nos grupos controle e experimento. GSH hepático e plasmático se mostraram significantemente maior nos animais parcialmente hepatectomizados.,em todos os tempos. Hiperglicemia estatisticamente significativa ocorreu nos ratos pós-HP nos tempos T2 e T3. A BT não apresentou qualquer alteração entre os grupos. CONCLUSÃO: Durante a regeneração hepática pós-HP em ratos há um aumento do estresse oxidativo e o fígado residual permanece apto na manutenção da homeostase orgânica.

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.
