Summary: Bilayer anticoagulant hydrogel tubes with inner layer containing NFC/PVA-heparin/poly-L-lysine nanoparticles and outer layer made of PCL sheaths were prepared and studied for use as small-diameter vascular grafts. The tubes exhibited prominent anticoagulation, sufficient burst pressure, good compliance, and potential for host cell infiltration and proliferation. The structure, anticoagulant property, and biocompatibility of the inner layer, as well as the impact of outer layer thickness on tube performance and mechanical properties, were investigated. The tissue compatibility and patency of the tubes were evaluated through implantation in animal models.

Summary: In this study, PTFE nanofibrous membranes were electrospun and poly(epsilon-caprolactone) (PCL) shish-kebab microstructures were induced on the surface of PTFE nanofibers to improve biocompatibility and mechanical properties. The deposition of PCL lamella improved the hydrophilicity of the PTFE membrane, leading to enhanced cell proliferation and adhesion. The PTFE/PCL composite film also exhibited good anti-platelet adhesion properties due to the inertness of PTFE surface. Cell proliferation could be regulated by controlling the integrity of the PCL crystal network.

Summary: The vasculature is a crucial physiological element in human tissues, and the formation of perfusable vascular networks is essential for tissue modeling. This study co-cultured endothelial cells and stromal cells in a hydrogel to form three-dimensional vascular networks. Comparing mesenchymal stem/stromal cells (MSCs) derived from bone marrow and adipose tissue, it was found that these cells supported the formation of mature and interconnected microvascular networks-on-a-chip. However, the origin of MSCs influenced the phenotypes of the vascular networks, with BMSCs inducing the formation of fully perfusable microvasculature and ASCs resulting in partially perfusable microvascular networks. The study also showed that BMSCs outperformed ASCs in terms of pericytic characteristics and gene expression related to vasculature maturation.

Summary: Mitochondrial dysfunction in white adipose tissue is associated with obesity. Human adipose-derived stromal/stem cells are a useful tool to study the underlying mechanisms of this dysfunction. Existing protocols for adipogenic differentiation alter the phenotype of white adipocytes and have varying effects on mitochondria. This study aims to find a protocol that can more faithfully recapitulate the white adipocyte phenotype observed in human adipose tissue.

Summary: Haemodialysis is expensive and has limitations in removing uraemic solutes, causing poor patient quality of life and large carbon footprint. Innovative dialysis technologies, such as portable, wearable and implantable artificial kidney systems, are being developed to address these issues. Challenges include the need for continuous regeneration of dialysate and improving toxin removal. Efforts to overcome these challenges include developing dialysate recycling systems and novel membranes combined with bioartificial kidneys.

Summary: Patients with end-stage kidney disease suffer from high levels of protein-bound uremic toxins. Conventional dialysis methods are ineffective in removing these toxins. A potential solution could be a bioartificial kidney composed of membranes with proximal tubule epithelial cells that actively secrete these toxins. However, the development of this bioartificial kidney is hampered by a lack of knowledge regarding the cytocompatibility of the dialysis fluid. This study shows that the dialysis fluid does not affect the viability or function of the cells, and efficiently clears the toxins from the perfusion fluid.

Summary: Tissue engineering offers a new approach for reconstructing large urethral defects, which currently lack optimal repair methods. Cell-seeded scaffolds, including the novel scPLCL(A2P) scaffold, show promise in preventing urethral stricture and promoting urothelial and stromal tissue regeneration. The scPLCL(A2P) scaffold supports the growth and phenotype maintenance of human urothelial cells (hUC) and human adipose-derived stromal cells (hASC) in both mono- and coculture environments.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
