Methodology for applied 4 MHz RF hyperthermia concomitant with<sup>31</sup>P NMR spectroscopic monitoring of murine tumours
Bibliographic record
Abstract
It has been generally found that solid tumours in vivo are more susceptible to destruction by heat than normal tissues. Hyperthermia has, thus, been employed in the treatment of cancer either applied alone or in combination with other modalities such as chemotherapy and radiotherapy. However, the critical mechanism(s) by which heat sensitizes and kills cells in the solid tumour remains poorly defined. Magnetic resonance spectroscopic monitoring of tumour metabolism during application of hyperthermia may provide important insight into the response to hyperthermic challenge. The implementation of dual antenna-coil methodology that provides for NMR spectroscopic monitoring (31P at 121 MHz) concomitant with applied 4 MHz RF hyperthermia in murine tumours is described herein, in some detail. This technology, which does not require advanced (and expensive) magnetic resonance imaging systems, should be readily adaptable by other laboratories with an interest in murine tumour models.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
