  • On the contrary, small size NPs with a diameter of 4-20 nm easily penetrate into deep tumor tissues, but they are more prone to rapid clearance and insufficient drug retention. (nature.com)
  • Smartly engineered nanocapsules can not only shrink and decompose into small-sized nanodrugs upon drug release but also can regulate the TME to overproduce reactive oxygen species for enhanced synergistic therapy in tumors. (nature.com)
  • The book provides a description of noninvasive imaging modalities in diagnosing cancerous tumors of the skin, proffers an analytic framework for assessing the applications of the imaging modalities, and summarizes the state of ongoing research. (e-booksdirectory.com)
  • The tumour microenvironment or niche is the vital non-cancerous compartment of the tumour structure. (irbbarcelona.org)
  • Pharmacologic inhibition of the leukotriene-generating enzyme arachidonate 5-lipoxygenase (Alox5) reduces metastasis, revealing the efficacy of using targeted therapy against a specific tumour microenvironment component ( 2 ). (irbbarcelona.org)
