In this study, we present an adaptive anisotropic finite element method (FEM) and demonstrate how computational efficiency can be increased when applying the method to the simulation of blood flow in the cardiovascular system. We use the SUPG formulation for the transient 3D incompressible Navier-Stokes equations which are discretised by linear finite(More)
The combination of CT imaging and photoacoustic (PA) imaging represents not only high resolution and ease of forming 3D visual image for locating tissues of interest, but also good soft tissue contrast and excellent high sensitivity, which is very beneficial to the precise guidance for photothermal therapy (PTT). The near infrared (NIR) absorbing Au(More)
The regulation of sperm capacitation is important for successful fertilization. Ginsenosides, the biologically effective components of ginseng, have been found to enhance intracellular nitric oxide (NO) production and the latter has recently been indicated to play a significant role in modulation of sperm functions. We investigated the effect of Ginsenoside(More)
In this paper, theranostic nanoparticles (MnP-DOX NPs) were fabricated by conjugating Mn-porphyrin onto the surface of doxorubicin (DOX)-loaded poly(lactic acid) (PLA) nanoparticles (DOX NPs) for potential T1 magnetic resonance imaging and pH-sensitive drug delivery. An in vitro drug release study showed that the release rate of DOX from MnP-DOX NPs was(More)
Photodynamic therapy (PDT) is a site-specific treatment of cancer involving the administration of a photosensitizer (PS) followed by the local light activation. Besides efficient PSs, image guidance is essential for precise and safe light delivery to the targeting site, thus improving the therapeutic effectiveness. Herein, we report the fabrication of(More)
A theranostic agent was successfully fabricated by the formation of Au nanoshell around poly(lactic acid) nanoparticles entrapping doxorubicin, followed by linking a Mn-porphyrin derivative on the Au shell surface through polyethylene glycol. The resulted agent exhibited excellent colloidal stability and long blood circulation time due to introducing(More)
The high intensity focused ultrasound (HIFU) and thermosensitive cerasomes (HTSCs) were successfully assembled by employing cerasome-forming lipid (CFL) in combination with the component lipids of conventional low temperature sensitive liposomes (LTSLs) including 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC),(More)
UNLABELLED The purpose of this work is to study the antimetastasis activity of gadolinium metallofullerenol nanoparticles (f-NPs) in malignant and invasive human breast cancer models. We demonstrated that f-NPs inhibited the production of matrix metalloproteinase (MMP) enzymes and further interfered with the invasiveness of cancer cells in tissue culture(More)
