PEGylated nanoparticles and macromolecules are increasingly used in cancer imaging and anticancer treatment. The role of receptor-mediated endocytosis in the efficacy of these agents, however, has not been clearly defined. Here, we developed a matched pair of endocytic and nonendocytic receptors to directly and unambiguously assess this issue. The(More)
Food security is a global and regional concern of rapidly increasing consequence. It is at risk of inattention because of competing crises, because of its theoretical amenability to previously effective, if temporary measures, most impressively with the so-called Green Revolution and because of the recourse to the global trade paradigm as a putative(More)
Poly(ethylene glycol) (PEG) is increasingly used in clinical and experimental medicine. However, quantification of PEG and PEGylated small molecules remains laborious and unsatisfactory. In this report, we stably expressed a functional anti-PEG antibody on the surface of BALB 3T3 cells (3T3/alphaPEG cells) to develop a competitive enzyme-linked(More)
Health issues occasionally intersect security issues. Health security has been viewed as an essential part of human security. Policymakers and health professionals, however, do not share a common definition of health security. This article aims to characterize the notions of health security in order to clarify what constitutes the nexus of health and(More)
SiO<sub>x</sub>C<sub>y</sub> thin films were deposited by plasma polymerization. The stress of the deposited SiO<sub>x</sub>C<sub>y</sub> thin films can be modified by adjusting the beam current, the anode voltage, and the flow rate of hexamethyldisiloxane (HMDSO) gas and oxygen. Reducing the beam current or increasing the flow rate of HMDSO gas increased(More)
Hollow spheres with size matching the dye's absorption band can greatly enhance light harvesting. The hollow spheres of 450e550 nm harvest light most efficiently for N719 dye molecules. Hollow spheres have higher conversion efficiency per unit volume than that of mesoporous spheres. a b s t r a c t This study elucidates the size effect on dye-sensitized(More)
