Large Language Models (LLMs) have emerged as the new recommendation engines, outperforming traditional methods in both capability and scope, particularly code generation applications. Our research reveals a novel provider bias LLMs, namely without explicit input prompts, these models show systematic preferences for services from specific providers their recommendations (e.g., favoring Google Cloud over Microsoft Azure). This holds significant implications market dynamics societal...
The quality (color, tenderness, juiciness, protein content, and fat content) of poultry meat is closely linked to age, with older birds typically exhibiting increased intramuscular (IMF) deposition. However, specific lipid metabolic pathways involved in IMF deposition remain unknown. To elucidate the mechanisms underlying changes, we conducted a study using geese at 2 distinct growth stages (70 300 d). Our findings regarding approximate composition revealed that as aged d, their acquired...
The proliferation and death of granulosa cells (GCs) in poultry play a decisive role follicular fate egg production. fluid (FF) contains variety nutrients genetic substances to ensure the communication between cells. Exosomes, as new intercellular communication, could carry transport proteins, RNA, lipids react on GCs, which had been found FF various domestic animals. Whether exosomes similar is unclear. In this study, geese, with low production, were chosen, effect GCs was investigated....

The quality of poultry goose meat is closely related to its marketable ages, with varying increasing age. Geese two ages (70-day and 120-day) were selected understand the mechanisms behind this effect. Darker redder meat; chewier higher water-holding capacity (WHC) as well greater protein intramuscular fat (IMF) content observed in breast muscle (BM) 120-day-old geese compared 70-day-old geese. Quantitative phosphoproteomics revealed up-regulated phosphorylated myofibrillar proteins...
The liver is the main site of fat synthesis and plays an important role in study deposition poultry. In this study, we investigated developmental changes duckling livers isolated primary duck hepatocytes. Firstly, observed morphological from embryonic period to first week after hatching. Liver weight increased with age. Hematoxylin-eosin Oil Red O staining analyses showed that hepatic lipids gradually during declined post-hatching. samples were collected 21-day-old embryos for hepatocyte...
The photoperiod is the predominant environmental factor that governs seasonal reproduction in animals; however, underlying molecular regulatory mechanism has yet to be fully elucidated. Herein, Yangzhou geese (Anser cygnoides) were selected at spring equinox (SE), summer solstice (SS), autumn (AE), and winter (WS), regulation of via light-driven cyclical secretion pineal melatonin was investigated. We show there variations laying rate GSI, while ovarian area decreased 1.5-fold from SS AE....
