Ultrasound is commonly utilized to determine the dynamic Young's moduli for estimating material deterioration or quantifying material parameters. This is either done with a resonance frequency analysis or ultrasound for rock or concrete specimens in geophysics or civil engineering. For ultrasound, these are typically cylindrical specimens measured in a through-transmission arrangement.

Activation of co-stimulatory pathways in cytotoxic T lymphocytes expressing chimeric antigen receptors (CARs) have proven to boost effector activity, tumor rejection and long-term T cell persistence. When using antigen-specific T cell receptors (TCR) instead of CARs, the lack of co-stimulatory signals hampers robust antitumoral response, hence limiting clinical efficacy. In solid tumors, tumor stroma poses an additional hurdle through hindrance of infiltration and active inhibition.

Adoptive T cell therapy (ACT) is highly effective in the treatment of hematologic malignancies, but shows limited success in solid tumors. Inactivation of T cells in the tumor milieu is a major hurdle to a wider application of ACT. Cytotoxicity is the most relevant activity for tumor eradication.

Bile acids (BAs) are produced by liver hepatocytes and were recently shown to exert functions additional to their well-known role in lipid digestion. As yet it is not known whether the mucosal-associated invariant T (MAIT) cells, which represent 10-15% of the hepatic T cell population, are affected by BAs. The focus of the present investigation was on the association of BA serum concentration with MAIT cell function and inflammatory parameters as well as on the relationship of these parameters to body weight.

Article Synopsis
  • Mucosal-associated invariant T-cells (MAIT) can respond to metabolites from vitamins produced by gut bacteria, and the study investigates how pesticides chlorpyrifos (CPF) and glyphosate (GLP) affect this interaction.
  • The results showed that CPF increased MAIT cell activation from certain bacteria, while GLP generally diminished this activation.
  • Exposure to CPF altered the production of vitamins riboflavin and folate by gut bacteria and modified their biosynthesis pathways, suggesting potential pro-inflammatory immune responses due to pesticide exposure.
