Expansive data, extensive model: Investigating discussion topics around LLM through unsupervised machine learning in academic papers and news.

This study presents a comprehensive exploration of topic modeling methods tailored for large language model (LLM) using data obtained from Web of Science and LexisNexis from June 1, 2020, to December 31, 2023. The data collection process involved queries focusing on LLMs, including "Large language model," "LLM," and "ChatGPT." Various topic modeling approaches were evaluated based on performance metrics, including diversity and coherence.

Altered monocyte-derived dendritic cell function in patients on hemodialysis: a culprit for underlying impaired immune responses.

Background: Patients with end-stage renal disease (ESRD) are known to have impaired immune function. Dendritic cells (DCs) are the major antigen-presenting cells that initiate primary immune responses, linking innate and adaptive immunity. Although suboptimal immune responses to vaccination, as frequently observed in ESRD patients, might suggest the presence of impaired DC function, the precise nature of altered DC function is not fully understood.

Primed monocytes: putative culprits of chronic low-grade inflammation and impaired innate immune responses in patients on hemodialysis.

Background: End-stage renal disease patients are known to be in a state of chronic low-grade inflammation and to have high infection-related morbidity and mortality. However, the precise mechanisms are not understood. The purpose of this study was to determine the mechanisms underlying chronic low-grade inflammation and defects in innate immune responses in hemodialysis (HD) patients.

Signaling pathway for 2,3,7,8-tetrachlorodibenzo-p-dioxin-induced TNF-alpha production in differentiated THP-1 human macrophages.

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a prototypic halogenated aromatic hydrocarbon (HAH), is known as one of the most potent toxicants. At least a part of its toxic effects appears to be derived from its ability to induce TNF-alpha production. However, the signaling pathway of TCDD that leads to TNF-alpha expression has not been elucidated.
