Article Abstract
Applications of fibrous meshes for localized chemotherapy have been limited by the lack of optimal carriers that are capable of releasing sufficient drug locally. To overcome this obstacle, we introduced Pluronic F127 (PF127) to the camptothecin (CPT)-loaded poly(lactic acid/glycolic acid) (PLGA) electrospun fibrous meshes, abbreviated as PPC, for modulation of drug release. These PPC meshes had smooth surface and high drug loading (5.6-6.8%). Addition of PF127 obviously improved the hydrophilicity of the meshes. Interestingly, the CPT release rate of PPC meshes was significantly higher than that of CPT-loaded PLGA (PLGA-CPT) meshes. Most importantly, incorporation of PF127 in the meshes led to significant reduction in the CT-26 viability compared to PLGA-CPT mesh. The improved anticancer effects of PPC meshes were mainly due to the induction of apoptosis in CT-26 cells. These findings suggest that PPC mesh could be a promising implantable system that may enhance the therapeutic efficacy and prevent tumor recurrence after surgical resection.

The identity of implant materials governs the antimicrobial efficacy of SET-M33.

The physical and chemical properties of implanted materials play a key role in their interaction with synthetic peptides that exert antimicrobial activity. In this study, we explored the diffusion properties and efficacy of the SET-M33 antimicrobial peptide in combination with artificial substrates, comprising cardiac implantable electronic devices (CIEDs) or porous protective envelopes. We found that porous materials, such as biosynthesized cellulose, polymeric meshes, and electrospun membranes, were conducive to SET-M33 diffusion.

Surgical meshes and patches used in abdominal surgery, despite their effectiveness, have a number of disadvantages that may lead to complications. This is due to the properties of the materials used for their construction and the structure of the implant itself. This paper presents an attempt to obtain an implant material, that could be used in surgery, combining the advantages of biodegradable and non-degradable polymers, while eliminating their weaknesses, additionally providing the possibility of using local pharmacotherapy.

Harmonious assessment of mesh effect in water sieve sampling for fibrous microplastics abundance.

College of Fisheries, Ocean University of China, Qingdao 266003, China. Electronic address:
Fibrous microplastic pollution in natural water is increasingly concerning because these particles could carry and release toxic substances, and be bioavailable of microplastics less than 100 μm, posing significant risks to ecosystems and human health. Effective monitoring and accurate data sharing are hampered by a lack of standardized sampling methods, particularly for assessing the impact of mesh size (hereafter referred to as mesh opening) on microplastics abundance. This study investigated the efficiencies of various mesh openings (50-500 μm) in water sieve sampling of fibrous microplastics using a continuous multi-layer filtration device.
