Injectable hydrogels, providing sustained release as implanted materials, have received tremendous attention. In this study, chitosan-based hydrogels were prepared via Schiff base reaction of the aldehyde groups on Poly(NIPAM-co-FBEMA) and the amine groups on chitosan. Owing to the dynamic covalent linkage, the SC/PNF hydrogels exhibit pH-responsive, reversible sol-gel transition, injectable, and self-healing capacity.

Article Synopsis
  • The study investigates how the microstructure characteristics of impervious surfaces, especially their roughness, affect street dust accumulation and erosion during different weather conditions.
  • Field data from 12 rainfall events showed a strong correlation between surface roughness and dust accumulation on sunny days (0.664) and scouring during rain (0.527).
  • By using a linear regression model, the research suggests that understanding surface roughness can help predict pollution loads in urban runoff, contributing valuable insights for managing non-point source pollution in cities.

Article Synopsis
  • The study examined how the arrangement and composition of permeable and impermeable surfaces in urban areas affect runoff and pollution, using landscape metrics to analyze these relationships.
  • Results showed that higher patch density (more fragmented surfaces) correlated positively with total runoff and pollutant loads, while larger patches had a negative impact, indicating that smaller, scattered patches contribute more to runoff than larger ones.
  • For planning urban landscapes, the research suggests transforming small, regular patches into larger, irregular ones to better control runoff and pollution, highlighting the importance of surface patterns in urban water management.

Most sponge city constructions in China are carried out in urban parcel-based catchments, and the quality and quantity of surface runoff can be controlled by several low impact development (LID) facilities. However, there are few reports on the generation and control of urban diffuse pollution. In this study, two areas with different hardening rates were compared to analyze the load conditions during the accumulation-wash-off-transport process of particulate pollutants.

Article Synopsis
  • Grey matter volume (GMV) loss has been found in patients with non-alcoholic cirrhosis, but the reasons behind this are still unclear, particularly the role of oxidative stress (OS).
  • A study with 34 cirrhotic patients and 27 healthy controls used MRI to assess GMV and measured serum malondialdehyde (MDA) levels as a marker of OS.
  • Results showed that cirrhotic patients had lower GMV and higher MDA levels compared to healthy controls, indicating a negative correlation between MDA and GMV, which suggests that oxidative damage may contribute to GMV loss in these patients.

Different combinations of low impact development (LID) technologies can be applied for control of urban non-point source pollution. There are currently few evaluations of urban non-point source pollution and pollution load reduction based on a combination of porous asphalt and bio-retention. Taking Shenzhen International Low Carbon City as an example, road-deposited sediments were collected prior to and after rainfall events.

A superparamagnetic iron oxide (SPIO) nanoshell and polyvinyl alcohol (PVA) based chemoembolization system for anti-cancer drug doxorubicin (DOX) delivery has previously been presented. We have also previously confirmed the feasibility and safety of this multifunctional system for carrying both DOX and SPIO nanoparticles in vitro. However, the pharmacokinetic and the therapeutic efficacy of this novel drug-delivery system in vivo is not yet clear, and as such was the subject of this study.
