Cancer therapy often requires frequent and high drug dosing. Yet, despite the significant progress in cancer research and the wide versatility of potent available drugs, treatment efficacy is still hurdled and often failed by the lack of pharmaco-selectivity to diseased cells, indiscriminate drug toxicities and poor patient compliance. Thus, innovative pharmaceutical solutions are needed to eff...

In this work, for better understanding of drug delivery systems, blood flow over a ceramic nanoparticle is investigated through microvessels. Drug is considered as a nanoparticle coated with the rigid ceramic. Due to the low characteristic size in the microvessel, the fluid flow is not continuum and the no-slip boundary condition cannot be applied. To solve this problem lattice Boltzmann method...

human immunodeficiency virus (hiv) is a public health challenge facing both developing and developed nations. although injecting drug use is even the main route of hiv transmission in iran, sexual route is rising gradually. vulnerable women have been considered as important bridging population for driving hiv epidemics. to increase the access to vulnerable women, in 2007, 5 pilot centers were e...

For almost two decades, scientists have been exploring the use of nanoparticles as drug vesicles capable protecting their cargo and deliver it to target site while evading detection by body.

Gelatin-hydroxyapatite-polylactic acid (PLA) nanocomposites were synthesized using five different formulations. The nanocomposites were loaded with ibuprofen and the amount of drug in the carriers was determined. X-ray diffraction (XRD) analysis was conducted before and after drug loading to ensure the presence of ibuprofen on the nanocomposites. Drug delivery was evaluated in phosphate buffere...

Extracellular vesicles (EVs) are secreted from any types of cells and shuttle between donor cells and recipient cells. Since EVs deliver their cargos such as proteins, nucleic acids, and other molecules for intercellular communication, they are considered as novel mode of drug delivery vesicles. EVs possess advantages such as inherent targeting ability and non-toxicity over conventional nanocar...

This paper reports a novel medication release and delivery mechanism as part of a next generation wireless capsule endoscope (WCE) for targeted drug delivery. This subsystem occupies a volume of only 17.9mm3 for the purpose of delivering a 1 ml payload to a target site of interest in the small intestinal tract. An in-depth analysis of the method employed to release and deliver the medication is...
