Biomagnetic fluid dynamics (BFD) is an emerging and promising field within fluid mechanics, focusing on the dynamics of bio-fluids like blood in the presence of magnetic fields. This research is crucial in the medical arena for applications such as medication delivery, diagnostic and therapeutic procedures, prevention of excessive bleeding, and treatment of malignant tumors using magnetic particles. This study delves into the intricacies of blood flow induced by cilia, carrying trihybrid nanoparticles (gold, copper, and titania), within a catheterized arterial annulus under a robust magnetic field.

The research sought to assess the therapeutic impact of resveratrol by biochemical, immunohistochemical, and histopathological analyses in a TiO-induced liver fibrosis model. Titanium dioxide (100 mg/kg body weight) was delivered for 15 days to induce liver fibrosis, either alone or in conjunction with resveratrol (30 mg/kg body weight) therapy for the same duration. Resveratrol has been identified as a crucial therapeutic drug that provides an alternative treatment method for TiO-induced liver fibrosis by mitigating inflammation, oxidative stress, and the expressions of α-SMA and 8-OHdG.

Previous studies have indicated the great performance of electrooxidation (EO) to mineralize per- and polyfluoroalkyl substances (PFASs) in water, but different anions presented in wastewater may affect the implementation of EO treatment in field applications. This study invetigated EO treatment of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), two representative perfluoroalkyl acids (PFAAs), using porous Magnéli phase titanium suboxide anodes in electrolyte solutions with different anions present, including NO3-, SO42-, CO32- and PO43-. The experiment results indicate that CO32- enhanced PFAS degradation, while NO3- suppressed the degradation reactions with its concentration higher than 10 mM.

Thermoplastic polyurethane (TPU) fabrics often possess good mechanical, waterproofing, and breathability properties. However, the resistance of TPU to excessive ultraviolet (UV) irradiation is poor and often does not meet the UV resistance requirements of fabrics. Electrospun nanofibers with a side-by-side structure can combine the advantages of different materials.

Introduction/objectives: Failures of osseointegrated implants pose a significant challenge in the medical field, often attributed to prolonged osseointegration periods and bacterial infections. Functionalization of Titanium Dioxide Nanotubes (TNTs) has emerged as a promising strategy to improve osseointegration and mitigate infections. This study aims to conduct a bibliometric analysis and systematic review to identify trends, gaps, and advancements in research on the functionalization of TNTs for osseointegration improvement.
