the goal of this research is to determine the feasibility of loading rifampin into mesoporous silica nanoparticles. rifampin was selected as a model lipophilic molecule since it is a well-documented and much used anti tuberculosis drug. the mesoporous silica nanoparticles were prepared by using tetraethyl ortho silicate and cetyltrimethyl ammonium bromide (as surfactant); the prepared nanoparti...

Drug Delivery In article number 2212210, Funan Liu, Hongjun Li, Zhen Gu, and co-workers present an oncolytic virus therapy that can target metastasis after systemic administration. Tumor cells have been pre-infected with serve as the delivery vehicle pathogenicity has eliminated by liquid nitrogen shock, but their metastasis-targeting ability is maintained integrity of cellular structure surfac...

Detection and prediction of drug delivery to the tumor interstitium are of critical importance in cancer chemotherapy. Prediction of drug delivery derived from standard pharmacokinetic models is frequently inadequate because of the complex nature of tumor blood flow and the microenvironment. Although drug concentrations can be directly sampled with microdialysis or in biopsy samples, we current...

although the conventional therapies have obviously improved the conditions of patients with cancer, some mechanisms of resistance have led scientists to use alternative agents that can penetrate in most solid tumors. furthermore, the success of cancer therapies depends on limiting the uptake of toxins to normal tissues and their selectivity to malignant cells. the involvement of natural and gen...

Integrin alphanubeta3 is found on a subset of tumor blood vessels where it is associated with angiogenesis and malignant tumor growth. We designed an alphanubeta3-targeted nanoparticle (NP) encapsulating the cytotoxic drug doxorubicin (Dox) for targeted drug delivery to the alphanubeta3-expressing tumor vasculature. We observed real-time targeting of this NP to tumor vessels and noted selective...
