Several nanoscale carriers (nanoparticles, liposomes, water-soluble polymers, micelles and dendrimers) have been developed for targeted delivery of cancer diagnostic and therapeutic agents. These carriers can selectively target cancer sites and carry large payloads, thereby improving cancer detection and therapy effectiveness. Further, the combination of(More)
It is well documented that transgenes with inverted repeats can efficiently trigger post-transcriptional gene silencing (PTGS), presumably via a double stranded RNA induced by complementary sequences in their transcripts. We show here that transgenes with intrinsic direct repeats can also induce PTGS at a very high frequency (80-100%). A transgene with(More)
UNLABELLED Endothelial cells in tumor angiogenesis are highly accessible, genetically stable and present unique molecular markers for targeted therapy. Neoplasia is also characterized by enhanced vascular permeability and disordered lymphatics so that both active and passive targeting strategies may play a role in localizing angiogenesis-targeted agents. To(More)
Virus diseases are among the key limiting factors that cause significant yield loss and continuously threaten crop production. Resistant cultivars coupled with pesticide application are commonly used to circumvent these threats. One of the limitations of the reliance on resistant cultivars is the inevitable breakdown of resistance due to the multitude of(More)
Fixed-dose combination (FDC) products are becoming a popular treatment option because of increased patient compliance and convenience, improved clinical effectiveness, and reduced cost to the patient, among several other reasons. A commonly applied approach for approval of a FDC product is demonstrating bioequivalence between the FDC and co-administration(More)
In Vitro-In Vivo Correlation (IVIVC) is being increasingly used to predict bioperformance of dosage forms without conducting animal and/or human studies which are not only time-consuming and expensive but also might be considered ethically undesirable. The main aim of IVIVC methods is to develop in vitro drug release methods which are simple, robust,(More)
In vitro cadaver skin permeation studies are often conducted to characterize the permeation profile of compounds for dermal delivery. However, its utility could be limited in the case of topical products because of lack of reliable prediction of in vivo skin kinetics. In this paper, the use of in vivo skin biopsy data to guide topical formulation(More)
This summary workshop report highlights presentations and over-arching themes from an October 2011 workshop. Discussions focused on best practices in the application of biopharmaceutics in oral drug product development and evolving bioequivalence approaches. Best practices leverage biopharmaceutic data and other drug, formulation, and patient/disease data(More)
Sites of neovascular angiogenesis are important chemotherapy targets. In this study, the synthesis, characterization, in-vivo imaging and biodistribution of a technetium-99m labeled, water-soluble, N-(2-hydroxypropyl) methacrylamide (HPMA) copolymer carrying doubly cyclized Arg-Gly-Asp motifs (HPMA copolymer-RGD4C conjugate) are reported. In vitro(More)
