A diabetic wound exemplifies the challenge of chronic, nonhealing wounds. Elevated blood sugar levels in diabetes profoundly disrupt macrophage function, impairing crucial activities such as phagocytosis, immune response, cell migration, and blood vessel formation, all essential for effective wound healing. Moreover, the persistent presence of pro-inflammatory cytokines and reactive oxygen species, coupled with a decrease in anti-inflammatory factors, exacerbates the delay in wound healing associated with diabetes.

Article Synopsis
  • The study investigates how the physical state of dietary fats (liquid vs. solid) affects inflammation and endotoxin levels in healthy men after consuming high-fat meals.
  • Fourteen participants consumed emulsions of palm stearin oil with different lipid states, and blood samples were taken at various times after each meal.
  • The results showed no significant differences in inflammatory markers between the lipid states, although some baseline characteristics of participants influenced responses, implying that lipid crystallinity does not have a major impact on short-term inflammation.

Purpose: Large cell neuroendocrine carcinoma (LCNEC) is a high-grade neuroendocrine malignancy that, like small cell lung cancer (SCLC), is associated with the absence of druggable oncogenic drivers and dismal prognosis. In contrast to SCLC, however, there is little evidence to guide optimal treatment strategies, which are often adapted from SCLC and non-small cell lung cancer approaches.

Experimental Design: To better define the biology of LCNEC, we analyzed cell line and patient genomic data and performed IHC and single-cell RNA sequencing of core needle biopsies from patients with LCNEC and preclinical models.
