Abstract

fetched live from OpenAlex

Objective:To observe angiogenesis surrounding laser channel and status of myocardial cells in ischemia area after transmycardial laser revascularization Methods: the 18 dogs were randomly divided into 3 group ,six served as non transmural group(NTG), six as transmural group(TG), six as control group(CG) Left anterial decend artery(LAD) was ligated at about the junction of its proximal and medial thirds to induce myocardial ischemia The 10~15 channels were created with the neodymium laser in ischemic area two months later, the dogs were sacrificed Image analysis system was engaged to evaluate the content of interstitial collagen, density of microvessels and areameter of microvessels Electronic microscope was used to observe the changes of mitochondria Results: at two months ①the density of microvessels around the channels both in TG and NTG was higher( P 0 05) than that of the control group, the areameter of TG was greater than that of NTG ②amount of collagen in CG was 19 43±2 65% versus in NTG 9 31±1 02% ( P 0 05) and versus in TG 5 19±0 54%( P 0 05) ③Degree of mitochondrial injury was normal or slightly damaged in TG, but were irreversible damaged in CG Conclusion: Transmycardial laser revascularization results in significant improvement in myocardial perfusion and induces angiogenesis in ischemic myocardium

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
