Simultaneous inhibition of metastasis and growth of breast cancer by co-delivery of twist shRNA and paclitaxel using pluronic P85-PEI/TPGS complex nanoparticles.

Jianan Shen et al.

Biomaterials, 34(5), 1581-1590 (2012-11-14)

The metastasis of breast cancer is the leading cause of cancer death in women, and the lung is a common location of a secondary tumor that has metastasized from the primary source tumor. In this work, an attempt to simultaneously

Structural characterization and antimicrobial properties of silver nanoparticles prepared by inverse microemulsion method.

Irshad A Wani et al.

Colloids and surfaces. B, Biointerfaces, 101, 243-250 (2012-09-27)

Silver nanoparticles have been synthesized in the inverse microemulsions formed using three different surfactants viz., cetyl-trimethyl ammonium bromide (CTAB), Tergitol and Triton X-100. We have done a systematic study of the effect of the surfactants on the particle size and

Pluronic P85 enhances the efficacy of outer membrane vesicles as a subunit vaccine against Brucella melitensis challenge in mice.

Neeta Jain-Gupta et al.

FEMS immunology and medical microbiology, 66(3), 436-444 (2012-11-21)

Brucellosis is the most common zoonotic disease worldwide, and there is no vaccine for human use. Brucella melitensis Rev1, a live attenuated strain, is the commercial vaccine for small ruminants to prevent B. melitensis infections but has been associated with abortions
