Abstract

fetched live from OpenAlex

The discovery of the adipocyte hormone leptin and the demonstration that severe obesity in ob/ob and db/db mice results from mutation of genes encoding leptin and its receptor, respectively, ushered in a new era of obesity research. Our investigation into mechanisms mediating CNS actions of insulin led us to ask whether the two hormones act on a common set of hypothalamic targets. Our finding that this is indeed the case prompted studies that continue to this day. While substantial progress has been made in understanding brain mechanisms of leptin action, translating this knowledge into more effective treatment of obesity remains an elusive goal.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
