    Spatial Single Cell Analysis of Tumor Microenvironment Remodeling Pattern in Primary Central Nervous System Lymphoma

    Scientists found that tumor cells may achieve a “tumor microenvironment (TME) remodeling pattern” through an “immune pressure-sensing model”, in which they could choose to reshape the TME into a barrier environment or a cold environment according to the immune pressure.

    Gas-Jet Propelled Hemostats for Targeted Hemostasis in Wounds with Irregular Shape and Incompressibility

    In order to counter the flushing effect of gushing blood, a gas-jet propelled powder hemostat ((COL/PS)4@CaCO3-T-TXA+) was developed. (COL/PS)4@CaCO3-T-TXA+ dove into the deep bleeding sites of complex wounds for targeted hemostasis.
