Abstract Background Microwave ablation (MWA) has become an alternative treatment for unresectable hepatocellular carcinoma (HCC), but it does not eliminate the risk of recurrence and metastasis after treatment. Recent studies have demonstrated that miR-34a presents decreased gene expression in residual tumours therapy can increase therapeutic effect arsenic trioxide against HCC, which brings ne...

Introduction : Nowadays, using drug delivery is an essential method to improve cancer therapy through decreasing drug toxicity and increasing efficiency of treatment. Silibinin (C25H22O10), a polyphenolic flavonoid which is isolated from the milk thistle plant, has various applications in cancer therapy but it has hydrophobic structure with low water solubility and bioavailability. To increase ...

Curcumin (CUR) is a unique natural compound with promising anticancer and anti-inflammatory activities. However, the therapeutic efficacy of curcumin was challenged in clinical trials, mostly due to its low bioavailability, rapid metabolism, and elimination. We designed a nanodrug form of curcumin, which makes it stable and substantially enhances cellular permeability and anticancer activity at...

In 2000, the National Institute of Health launched the National Nanotechnology Initiative to support, coordinate, and advance research and development of nanoscale projects. The impact of this new program on health-science related research and development became quickly visible. Broad governmental financial support advanced the start of new, and the deepening of already existing, interdisciplin...

The 2D monolayer cell culture model is often the first step in the prediction of the success or failure of a nanoparticle-based drug delivery system. However, there is often poor translation between the 2D monolayer in vitro results and the nanoparticle-drug performance in vivo. One possible way of bridging this gap is the use of multicellular tumor spheroids (MCTSs) as an intermediate in vitro...

Multidrug resistance (MDR) remains a major challenge for providing effective chemotherapy for many cancer patients. To address this issue, we report an intelligent polymer-based drug co-delivery system which could enhance and accelerate cellular uptake and reverse MDR. The nanodrug delivery systems were constructed by encapsulating disulfiram (DSF), a P-glyco-protein (P-gp) inhibitor, into the ...

background: except in emergency cases, all patients should be seen first by a primary healthcare physician who decides whether a referral to secondary care is necessary. the present study examined the reasons for patient self-referral to specialists. methods: a random sample of 1036 individuals was selected from people attending public outpatient clinics and specialists’ offices in the private ...
