Article Synopsis
  • This study compared the effectiveness of optimized vs. unoptimized large language models (LLMs) in answering orthopedic questions using a specialized knowledge base.
  • A knowledge base was created using clinical guidelines and authoritative publications, and 30 orthopedic questions were posed to both types of LLMs, with responses evaluated by experienced orthopedic surgeons.
  • Results indicated that optimization led to significant improvements across all models in quality, accuracy, and comprehensiveness, suggesting that tailored knowledge bases can enhance LLM performance in specialized fields.

Purpose: Pancreatic cancer (PC) is one of the most lethal malignant gastrointestinal tumors (GI) characterized by a poor prognosis. Ferroptosis is an emerging programmed cell death that plays an essential role in the progression of various cancers. Ferroptosis is driven by iron-dependent phospholipid peroxidation and is regulated by mitochondrial activity, lipid peroxidation, and reactive oxygen species (ROS).

Grayanane diterpenoids, possessing a unique 5/7/6/5 tetracyclic system, exist exclusively in plants of the Ericaceae family. Owing to their various skeletons, complex structures, and diverse bioactivities, grayanoids have been the topic of research in many phytochemical and pharmacological laboratories, offering opportunities for the development of new drugs with analgesic, anti-inflammatory, and protein tyrosine phosphatase 1B (PTP1B) properties. Recently, a number of new grayanane diterpenoids with unprecedented carbon skeletons have been obtained from plants of the Ericaceae family, and they exhibit diverse biological properties, such as agalgesic, antinociceptive, anticancer, antiviral, antifeedant, insecticidal, toxicity, and PTP1B.
