To develop a novel docetaxel (DOC)-loaded lipid microbubbles (MBs) for achieving target therapy and overcoming the poor water-solubility drawback of DOC. A novel DOC-loaded microbubble (DOC + MB) was prepared by lyophilization and the physicochemical properties including ultrasound contrast imaging of the liver were measured. The anti-tumor effect of the(More)
BACKGROUND A vaccine for enterovirus 71 (EV71) is needed to address the high burden of disease associated with infection. We assessed the efficacy, safety, immunogenicity, antibody persistence, and immunological correlates of an inactivated alum-adjuvant EV71 vaccine. METHODS We did a randomised, double-blind, placebo-controlled, phase 3 trial. Healthy(More)
BACKGROUND & AIMS Even though various experimental therapeutic approaches for chronic hepatitis B infection have been reported, few of them have been verified by clinical trials. We have developed an antigen-antibody (HBsAg-HBIG) immunogenic complex therapeutic vaccine candidate with alum as adjuvant (YIC), aimed at breaking immune tolerance to HBV by(More)
BACKGROUND The safety of the immune complexes composed of yeast-derived hepatitis B surface antigen (HBsAg) and antibodies (abbreviated as YIC) among healthy adults and chronic hepatitis B patients has been proved in phase I and phase IIa trial. A larger number of patients for study of dosage and efficacy are therefore needed. METHODS AND PRINCIPAL(More)
Our previous study has shown that P1 polypeptide-loaded microbubbles (clot-targeted microbubbles, TMB) are effective for thrombolysis and recanalization in a 0.5 h cerebral thrombosis rabbit model when combined with low-frequency ultrasound (LFUS, 0.8 MHz). However, the thrombolytic effects of TMB combined with LFUS are still unclear in a 6 h cerebral(More)
BACKGROUND Enterovirus 71 (EV71) outbreaks are a socioeconomic burden, especially in the western Pacific region. Results of phase 1 clinical trials suggest an EV71 vaccine has a clinically acceptable safety profile and immunogenicity. We aimed to assess the best possible dose and formulation, immunogenicity, and safety profile of this EV71 vaccine in(More)
BACKGROUND Enterovirus 71 (EV71) is highly contagious and can cause severe complications. A safe and effective vaccine is needed. We assessed the reactogenicity and immunogenicity of an inactivated, alum-adjuvanted EV71 vaccine in this study. METHODS A randomized, double-blind, placebo-controlled clinical trial was undertaken in 360 healthy participants(More)
A new microbubble loaded with urokinase (uPA-MB) was explored in a previous study. However, its zeta potential and ultrasound contrast imaging properties and its thrombolytic effects when combined with low-frequency ultrasound (LFUS) were unclear. The zeta potential and ultrasound contrast imaging property of 5 uPA-MBs loading with 50,000 IU uPA was(More)
INTRODUCTION Z4A5 is a novel peptide that inhibits platelet aggregation and formation of platelet thrombi, but the mechanism of its anti-platelet effects remains unknown. This study explores the anti-platelet effect and mechanism of Z4A5. METHODS We investigated the anti-platelet activity of Z4A5 on platelet aggregation induced by adenosine diphosphate(More)
