Relationship Between Dietary Inflammatory Index and Carotid Artery Calcification in Patients with Ischemic Stroke.

Background And Purpose: Diet may influence systemic inflammatory status, vascular calcification, and, therefore, the development of atherosclerosis. The Dietary Inflammatory Index (DII) is a measure of the inflammatory potential of diet. Although previous studies have examined the relationship between DII and cardiovascular diseases, its specific association with carotid artery calcification in ischemic stroke patients remains insufficiently explored.

IRF1 transcriptionally up-regulates CXCL10 which increases CD8 T cells infiltration in colorectal cancer.

Tumor-infiltrating CD8 T cell is a robust predictor of outcome and immunotherapy response in patients with CRC. However, limited introduction of intratumoral CD8 T cells remains a barrier for treatment of CRC. One of the most effective but difficult therapy for CD8 T cells entering the tumor is activating chemokine receptors.

Carbon microspheres prepared from soluble starch hydrothermal carbonization for extending thermal stability of water-based drilling fluid.

This study employed hydrothermal carbon microspheres (HCMs) as high-temperature stabilizers in drilling fluids. The HCMs were synthesized through a green hydrothermal carbonization method, using soluble starch as the precursor. The impact of HCMs on the thermal stability of xanthan, polyanionic cellulose and synthetic polymer solutions was assessed by comparing their rheological changes before and after thermal aging.
