In the present work, docetaxel (DTX) and retinoic acid (RA) co-loaded micelles were developed for synergistic prostate cancer therapy. PEG-RA RA-PEG-RA synthesized subsequently used loading of DTX RA. The as prepared DTX/RA@RA-PEG-RA exhibit smaller size higher drug capacity compared to DTX/RA@PEG-RA micelles. in vitro release study shows that similar behaviours which exhibits fast RA sustained...

Coenzyme Q10 (CoQ10) has a wide range of physiological functions and therapeutic value. However, its biomedical application as health product or drug is limited by insolubility low bioavailability. Single-walled carbon nanotubes (SWCNTs) have attracted great interest for agent delivery due to their unique properties. In this study, the pristine SWCNTs are purified with different oxidizing acid,...

We here exploit pH-responsive nanogels as carriers to deliver functional anti-GFP siRNA and superparamagnetic IONPs to HeLa-GFP cells. The siRNA release via pH-mediated endosomal escape is shown. The IONPs act first as magnetofection agents to boost cellular uptake and then as probes to track the release mechanism by electron microscopy.

Cardiac electrical dynamics are governed by cellular-level properties, such as action potential duration (APD) restitution and intracellular calcium (Ca) handling, and tissue-level properties, including conduction velocity restitution and cell-cell coupling. Irregular dynamics at the cellular level can lead to instabilities in cardiac tissue, including alternans, a beat-to-beat alternation in t...

Here we report a new peptide modified mesoporous silica nanocontainer (PMSN) as a novel controlled release system. The peptides are part of a stimuli responsive nanovalve and ensure an efficient cellular uptake.

Biophysical-factor-dependent cellular uptake of nanoparticles (NPs) through receptor-diffusion-mediated endocytosis bears significance in pathology, cellular immunity and drug-delivery systems. Advanced nanotechnology of NP synthesis provides methods for modifying NP surface with different ligand distributions. However, no report discusses effects of ligand distribution on NP surface on recepto...

Objective(s): Combination anticancer therapy holds promise for improving the therapeutic efficacy of chemotherapy drugs such as doxorubicin (DOX) as well as decreasing their dose-limiting side effects. Overcoming the side effects of doxorubicin (DOX) is a major challenge to the effective treatment of cancer. Zinc oxide nanoparticles (ZnO NPs) are emerging as potent tools for a wide variety of b...

To evaluate the contribution of blood cellular elements to inter-organ transport of amino acids, net exchange across the leg and splanchnic bed of 17 amino acids was determined in seven healthy postabsorptive subjects by use of both whole blood and plasma for analysis. Arterial-portal venous differences were measured in five additional subjects undergoing elective cholecystectomy. By use of who...
