In response to the dust pollution problem in open-pit mines, an environmentally friendly network structure with a dust suppressor structure was prepared by grafting acrylamide (AM) monomers onto xanthan gum (XG). The results show that the polymer produced from 1 g XG, 15 g AM, and 0.45 g trimethylolpropane triglycidyl ether (TTE) had a more orderly structured gel with a viscosity of 81.

Moreover, abnormal tumor vasculature interacts with immune cells, forming a vicious cycle that further interferes with anti-tumor immunity and promotes tumor progression. Our pre-basic found excellent anti-tumor effects of c-di-AMP and RRx-001, respectively, and we further explored whether they could be combined synergistically for anti-tumor immunotherapy.
