The ultimate goal of drug delivery research is to help patients by developing clinically useful formulations. During the last several decades controlled drug delivery technology has advanced significantly , leading to the development of various clinical formulations improving patient compliance and convenience [1]. Current technologies allow delivery of(More)
Estrogen replacement therapy in postmenopausal women may reduce the risk of Alzheimer's disease, possibly by ameliorating neuronal degeneration. In the present study, we examined the neuroprotective spectrum of estrogen against excitotoxicity, oxidative stress, and serum-deprivation-induced apoptosis of neurons in mouse cortical cultures. 17beta-estradiol(More)
As an alternative to cell specific cancer targeting strategies (which are often afflicted with the heterogeneity of cancer cells as with most biological systems), a novel polymeric micelle constitute of two block copolymers of poly(L-lactic acid)-b-poly(ethylene glycol)-b-poly(L-histidine)-TAT (transactivator of transcription) and(More)
Phenylboronic acid (PBA)-mediated tumor targeting nanovector is an attractive strategy for enhancing siRNA delivery and treatment of metastatic cancers. However, its nonspecific binding with various biological membranes containing cis-diol moieties restricts its potential application by systematic administration. Herein, we constructed a novel pH-activated(More)
Cancer stem cells (CSCs) are a small subset of cancer cells responsible for maintenance and progression of several types of cancer. Isolation, propagation, and the differentiation of CSCs in the proper stem niches expose the intrinsic difficulties for further studies. Here we show that induced cancer like stem cells (iCLSCs) can be generated by in vitro(More)
Endosomal entrapment is one of the main barriers that must be overcome for efficient gene expression along with cell internalization, DNA release, and nuclear import. Introducing pH-sensitive ionizable groups into the polycationic polymers to increase gene transfer efficiency has proven to be a useful method; however, a comparative study of introducing(More)
