Tumor vasculature is critically dependent on platelet mediated hemostasis and disruption of the same can augment delivery of nano-formulation based chemotherapeutic agents which depend on enhanced permeability and retention for tumor penetration. Here, we evaluated the role of Clopidogrel, a well-known inhibitor of platelet aggregation, in potentiating the(More)
Nanoscale drug delivery vehicles have been extensively studied as carriers for cancer chemotherapeutics. However, the formulation of platinum chemotherapeutics in nanoparticles has been a challenge arising from their physicochemical properties. There are only a few reports describing oxaliplatin nanoparticles. In this study, we derivatized the monomeric(More)
Pancreatic cancer remains the deadliest of all cancers, with a mortality rate of 91%. Gemcitabine is considered the gold chemotherapeutic standard, but only marginally improves life-span due to its chemical instability and low cell penetrance. A new paradigm to improve Gemcitabine’s therapeutic index is to administer it in nanoparticles, which favour its(More)
BACKGROUND AND PURPOSE The goal of this study is to combine temporary endovascular bypass (TEB) with a novel shear-activated nanotherapeutic (SA-NT) that releases recombinant tissue-type plasminogen activator (r-tPA) when exposed to high levels of hemodynamic stress and to determine if this approach can be used to concentrate r-tPA at occlusion sites based(More)
BACKGROUND AND PURPOSE One of the new challenges to improve radiotherapy is to increase the ionizing effect by using nanoparticles. The interest of titanate nanotubes (TiONts) associated with radiotherapy was evaluated in two human glioblastoma cell lines (SNB-19 and U87MG). MATERIALS AND METHODS Titanate nanotubes were synthetized by the hydrothermal(More)
Nanoencapsulation of chemotherapeutics is an established method to target breast tumors and has been shown to enhance the efficacy of therapy in various animal models. During the past two decades, the nucleoside analog Gemcitabine has been under investigation to treat both recalcitrant and localized breast cancer, often in combination with other(More)
Expression of P2Y12 receptors has been documented in some cancer cell lines like C6 glioma, renal carcinoma and colon carcinoma. However, its direct role in altering response to chemotherapeutics has not been studied. In this study, we characterize the expression of P2Y12 receptor in breast cancer cell lines and evaluate its role in enhancing the cytotoxic(More)
The vascular endothelium and shear stress are critical determinants of physiological hemostasis and platelet function in vivo, yet current diagnostic and monitoring devices do not fully incorporate endothelial function under flow in their assessment and, therefore, they can be unreliable and inaccurate. It is challenging to include the endothelium in assays(More)
OBJECTIVE To determine the complete sequences of glycoprotein (M) gene of Crimean-Congo hemorrhagic fever virus (CCHFV) Chinese isolates (Xinjiang hemorrhagic fever virus, XHFV) BA66019, BA8402 BA88166 and to compare and analyze the relationships among the viruses. METHODS Based on the conserved reverse complementarity of the CCHFV genomic termini, a(More)
