Microvessel Remodeling in Cerebral Ischemia
Bibliographic record
Abstract
The neurovascular (NV) unit, broadly defined as a segment of brain vasculature, is composed of functionally integrated cellular (including brain endothelial cells, astrocytes, pericytes, and smooth muscle cells) and acellular elements that form the basement membrane. Brain insults or conditions characterized by tissue hypoxia induce dramatic changes in the NV unit that include the disruption of interendothelial tight junctions, breakdown of the basal lamina, and endothelial proliferation, migration, and reorganization to form new capillaries and microvessels. This NV remodeling is controlled by a complex interplay of numerous mediators originating from cellular components of the NV unit and from breakdown of the extracellular matrix. Several of these mediator families are also involved in neuronal remodeling, thus providing for integration of vascular and neuronal responses to the ischemic state. On the global molecular scale, changes in ischemic cerebral microvessels include temporally controlled regulation of genes and proteins involved in cell cycle, blood-brain barrier phenotypic properties, cell proliferation, motility, and inflammation. The integration/coordination of angiogenic and neuronal remodeling during postischemic brain recovery is an important determinant of the overall neurological outcome.

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.
