Diethyl dithiocarbamic acid, a possible nuclear factor kappa B inhibitor, attenuates ischemic postconditioning-induced attenuation of cerebral ischemia–reperfusion injury in mice
Bibliographic record
Abstract
The present study was designed to pharmacologically investigate the possible role of nuclear factor kappa B (NF-kappaB) in the reversal of global cerebral injury induced by ischemia and reperfusion after ischemic postconditioning. Bilateral carotid artery occlusion for 17 min followed by reperfusion for 24 h was employed to produce ischemia- and reperfusion-induced cerebral injury in mice. Cerebral infarct size was measured by using triphenyltetrazolium chloride staining. Memory was evaluated using the Morris water maze test. The rotarod test was employed to assess motor incoordination. Bilateral carotid artery occlusion followed by reperfusion produced a marked increase in cerebral infarct size, impairment of memory, and motor coordination. A set of 5 episodes of carotid artery occlusion for a period of 10 s and reperfusion of 10 s (ischemic postconditioning) significantly prevented ischemia-reperfusion-induced cerebral infarct size and behavioral deficits measured in terms of loss of memory and motor coordination. Diethyl dithiocarbamic acid sodium salt trihydrate (DDA) (100 mg/kg, i.p.), an inhibitor of NF-kappaB, given 30 min before ischemia attenuated the beneficial effects of ischemic postconditioning. It may be concluded that the beneficial effects of ischemic postconditioning on global cerebral ischemia- and reperfusion-induced cerebral injury and behavioral deficits may involve activation of the NF-kappaB-linked pathway.

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.
