Zeaxanthin augments CD8 effector T cell function and immunotherapy efficacy.

The detailed mechanisms underlying the regulatory significance of dietary components in modulating anti-tumor immunity remain largely unknown. Here, we apply a co-culture-based screening approach using a blood nutrient compound library and identify zeaxanthin (ZEA), a dietary carotenoid pigment found in many fruits and vegetables and known for its role in eye health, as an immunomodulator that enhances the cytotoxicity of CD8 T cells against tumor cells. Oral supplementation with ZEA, but not its structural isomer lutein (LUT), enhances anti-tumor immunity in vivo.

Trans-vaccenic acid reprograms CD8 T cells and anti-tumour immunity.

Diet-derived nutrients are inextricably linked to human physiology by providing energy and biosynthetic building blocks and by functioning as regulatory molecules. However, the mechanisms by which circulating nutrients in the human body influence specific physiological processes remain largely unknown. Here we use a blood nutrient compound library-based screening approach to demonstrate that dietary trans-vaccenic acid (TVA) directly promotes effector CD8 T cell function and anti-tumour immunity in vivo.

Biomechanical Effects of Thoracolumbosacral Orthosis Design Features on 3D Correction in Adolescent Idiopathic Scoliosis: A Comprehensive Multicenter Study.

Study Design: Multicenter numerical study.

Objective: To biomechanically analyze and compare various passive correction features of braces, designed by several centers with diverse practices, for three-dimensional (3D) correction of adolescent idiopathic scoliosis.

Summary Of Background Data: A wide variety of brace designs exist, but their biomechanical effectiveness is not clearly understood.

Steatite Powder Additives in Wood-Cement Drywall Particleboards.

The objective of this study was to develop a new drywall wood-based particleboard as an alternative to gypsum board. Various development iterations have led to the use of wood particles, steatite powder and Portland cement. The resulting outcome shows that screw withdrawal resistance was improved by 37% and bending properties by 69% compared to gypsum board of a similar density (0.

Mainstem Bronchial Diameters and Dimensions in Infants and Children: A Systematic Review of the Literature.

Anatomic measurements of the right (RMB) and left mainstem bronchi (LMB) in infants and children have been accomplished using various modalities. The objective of the present review was to determine whether enough data were available to provide standardized lower airway dimensions in the pediatric population. For the present study, 12 studies with data of the lower pediatric airway dimensions of 1,611 children published from 1923-2020 were reviewed and analyzed.
