Abstract

fetched live from OpenAlex

Infections caused by the gram-negative bacterium Helicobacter pylori are associated with several pathways that include epidermal growth factor receptor (EGFR) and production of vascular endothelial growth factor receptor (VEGF).Of the several proteins secreted by H. pylori, HP0175 a peptidyl prolyl cis-, trans-isomerase (PPIase) has been linked to bind to toll-like receptors (TLR) allowing for the transactivation of EGFR and VEGF.TLRs are major players in innate immunity through their ability to recognize pathogens such as bacteria, fungi or viruses.HP0175 also causes cell damage, apoptosis and inflammatory responses.The following protein was initially crystallized as a homodimer (PDB ID:5EZ1), complexed with its inhibitor indole-2-carboxylic acid (I2CA) at 2.4 Å resolution.Here, we examine apo-HP0175 as a monomer with structure resolution of 2.34 Å. Apo-HP0175 crystallizes in space group p3121, with unit cell dimensions a=b=91.5 Å, c=67.7 Å with one molecule in the asymmetric unit.

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.
