To address concern of the dispersion property of hydrophilic drugs of excess dose loaded in a hydrophobic poly(lactic acid) (PLA) matrix, this work developed a PLA and PLA-b-polyethylene glycol (PEG) composite scaffold ( w/w=80/20) and studied its carrier properties for aspirin as a model hydrophilic drug. The porous functional scaffolds were prepared from PLA and PLA-b-PEG solutions with the dose of 5, 10, and 15 wt % aspirin preloaded. The products and control samples of pure PLA with the same loading amount for comparison were characterized by scanning electron microscopy and X-ray diffraction to examine the miscibility and porous structure. Rapid degradations in a strongly basic solution were performed to determine the actual loading amount and the encapsulation ratio. The in vitro release in phosphate buffer saline (PBS) at 37.5 degrees C indicated that the addition of amphiphilic block polymer may efficiently enhance the dispersion property and stabilize the release of hydrophilic drugs, especially with a high loading dose.

Effect of loading history on material properties of human heel pad: an in-vivo pilot investigation during gait

Zhao-lin Teng, Xiong-gang Yang, Xiang Geng, Yan-jie Gu, Ran Huang, Wen-ming Chen, Chen Wang, Li Chen, Chao Zhang, Maimaitirexiati Helili, Jia-zhang Huang, Xu Wang, Xin Ma

Summary: This study developed a novel dynamic measurement technique to test the material properties and investigate the effect of continuous compression load on the structural and mechanical properties of the human heel pad during actual gait. The results showed that repetitive loading decreased the primary thickness and viscous modulus of the heel pad, while age was negatively correlated with the primary thickness and peak strain, and positively correlated with the viscous modulus.

Summary: Food preservation is crucial for ensuring food safety and quality. Gaseous ClO2 has gained attention as an effective and eco-friendly preservation technique, with strong oxidizing properties and high efficacy in inactivating microorganisms. However, challenges such as large-scale generation, cost, and environmental considerations limit its widespread use in the food industry. This review provides an overview of the research on gaseous ClO2, including preparation methods, preservation mechanisms, and predictive kinetic models. It also summarizes the impact of gaseous ClO2 on the quality of fresh produce and low-moisture foods. Future studies should focus on addressing the challenges and developing standardized protocols and databases for its safe and effective use.

Summary: A rapid and efficient method using alkyl-functionalized magnetic nanoparticles-based extraction technique combined with Ultra-High Performance Liquid Chromatography was developed for detecting trace amounts of polycyclic aromatic hydrocarbons in tea leaves. The C-18-alkyl coating was found to be effective in separating polycyclic aromatic hydrocarbons. The magnetism of the nanomaterials accelerated the extraction process while their high surface ratio enabled desirable dispersity in the sample matrix. Moreover, the adsorbents can be washed and reused 30 times without compromising recovery, greatly reducing the budget.
