Reduction-Controlled Release of Organic Nanoparticles from Disulfide Cross-linked Porous Polymer
Reduction-controlled
release is favored for many applications.
The cleavage of disulfide bonds is known to be sensitive to reducing
agents. Here, a cross-linker containing a disulfide bond is prepared
and then used to prepare cross-linked porous polymer via an emulsion
templating approach. Oil-in-water (O/W) emulsions are first formed
where an organic dye is dissolved in the oil droplet phase and monomer/cross-linker/surfactant
are added into the continuous aqueous phase. By polymerizing the O/W
emulsion followed by freeze-drying, organic nanoparticles are formed <i>in situ</i> within the disulfide-cross-linked porous polymer.
The release of organic nanoparticles in water is demonstrated and
can be tuned by the presence of reducing agents such as dithiothreitol
and trisÂ(2-carboxyethyl)Âphospine. This approach has the potential
to be used for the reduction-controlled release of poorly water-soluble
drug nanoparticles from porous polymers or hydrogels
Transarterial Chemoembolization in Combination with Local Therapies for Hepatocellular Carcinoma: A Meta-Analysis
<div><p>Background</p><p>In previous randomized trials, transarterial chemoembolization (TACE) has shown an improvement of survival rate in hepatocellular carcinoma (HCC) when combined with radiofrequency ablation (RFA), percutaneous ethanol injection (PEI) or other therapies. The aim of this meta-analysis was to evaluate the effectiveness of combination therapy of TACE with RFA, PEI, radiotherapy (RT), three-dimensional conformal radiation therapy (3D-CRT) or High-Intensity Focused Ultrasound (HIFU).</p> <p>Methods</p><p>Randomized or nonrandomized studies comparing TACE combined with RFA, PEI, RT, 3D-CRT or HIFU with TACE alone for HCC were included. Meta-analysis was performed using a fix-effects model in RCTs and a random-effects model among the observational studies.</p> <p>Results</p><p>10 randomized trials and 18 observational studies matched the selection criteria, including 2497 patients (682 in RCTs, 1815 in non-RCTs). Meta-analysis of RCTs showed that the combination of TACE and PEI ((RR)<sub>1</sub><sub>-</sub>year=1.10, 95%CI=0.99-1.22, p=0.073; (RR)<sub>3</sub><sub>-</sub>year=2.32, 95%CI=1.52-3.53, p<0.001), TACE+RT ((RR)<sub>1</sub><sub>-</sub>year=1.37, 95%CI=1.11-1.70, p=0.004; (RR)<sub>3</sub><sub>-</sub>year=2.32, 95%CI=1.44-3.75, p=0.001) were associated with higher survival rates. The results of observational studies were in good consistency with that of RCTs. Furthermore, TACE plus 3D-CRT ((RR)<sub>1</sub><sub>-</sub>year=1.22, 95%CI=1.06-1.41, p=0.005; (RR)<sub>3</sub><sub>-</sub>year=2.05, 95%CI=1.48-2.84, p<0.001) and TACE plus HIFU ((RR)<sub>1</sub><sub>-</sub>year=1.16, 95%CI=1.01-1.33, p=0.033; (RR)<sub>3</sub><sub>-</sub>year=1.66, 95%CI=1.12-2.45, p=0.011) have introduced marked survival benefit when pooling results from observational studies.</p> <p>Conclusions</p><p>This meta-analysis demonstrated that TACE combined with local treatments, especially PEI, HIFU or 3D-CRT could improve the overall survival status than performing TACE alone. Importantly, these results need to be validated in further high-quality clinical trials.</p> </div
Experts’ perspectives.
Globally, old urban neighborhood transformation has become a new urban sustainability focus for its significant contribution to the United Nation’s Sustainable Development Goal 11. A regeneration-oriented approach is particularly important for Chinese cities with a dwindling land supply, obsoleting infrastructure, and inadequate standard of living. Using a mixed-methods approach informed by BREEAM Communities, we examined two Chinese initiatives—old urban neighborhood renewal (OUNR) and sponge city development (SCD)—through a comprehensive study of pilot project sustainability, policy emphases and gaps, and broader governance implications. We found that SCD’s top-down technocratic management was highly efficient in enhancing neighborhood hydrological functions and physical environment. However, successes were undermined by the lack of climate considerations and civic participation. Besides actionable recommendations for applied scholarship and policymaking in China, we provide insight into how the OUNR/SCD initiatives may broadly inform worldwide urban regeneration practices through project and policy experimentations that build adaptive capacity.</div
