The changing world and the increasing use of nanomaterials in industry have caused industrial nano wastes to enter water oceans recent years. By a similar mechanism, plastic that waters erode over time turn into microplastics. Fish, which encounter micro & pollutants (MNP) their habitats, ingest these materials through food chain, respiration direct contact. Although pollution attracts attention media society as result mass fish deaths, disruptions reproductive cycles exposed MNPs anomalies juvenile development stages threaten future population aquatic ecosystems. Fish experience limitations ability reproduce or produce offspring with are at risk facing extinction within short timeframe. In this chapter, effects various microplastics on systems discussed an awareness is tried be created.

Tumors grow by receiving oxygen and nutrients from the surrounding blood vessels, leading to rapid angiogenesis. This results in functionally structurally abnormal vasculature characterized high permeability irregular flow, causing hypoxia within tumor microenvironment (TME). Hypoxia exacerbates secretion of pro-angiogenic factors such as vascular endothelial growth factor (VEGF), further perpetuating vessel formation. environment compromises efficacy radiotherapy, immunotherapy, chemotherapy. In this study, we developed a pH-sensitive liposome (PSL) system, termed OD_PSL@AKB, co-deliver (OD) razuprotafib (AKB-9778) tumors. system rapidly responds acidic TME alleviate inhibit VEGF secretion, restoring VE-cadherin expression hypoxic cell/cancer cell cocultures. Our findings highlight potential OD_PSL@AKB normalizing improving therapeutic efficacy.

Bovine lactoferrin (bLf) is a milk-derived protein that exhibits multiple biological activities and has been explored towards different therapeutic applications. Since this molecule susceptible to degradation some of its properties depend on tertiary structure, the encapsulation bLf in stimuli-responsive formulations provides an added value potentiate when administered. Plasmonic magnetoliposomes emerge as promising nanosystems for dual hyperthermia (magneto-photothermia) local therapy, since combination magnetic gold nanoparticles (NPs) single nanosystem (multifunctional liposomes) enables targeting controlled release encapsulated drugs. In work, plasmonic (PMLs) containing manganese ferrite (28 nm size) (~ 5 functionalized with 11-mercaptoundecanoic acid or octadecanethiol, were synthesized loaded bLf. The structural, optical measured by TEM, SQUID UV/vis/NIR absorption spectroscopy. Specific Absorption Rate was determined assess capabilities photothermal hyperthermia. Finally, Saccharomyces cerevisiae used eukaryotic cellular model activity mechanism entry bLf-loaded PMLs, through counting colony forming units fluorescence microscopy, respectively. results demonstrate PMLs are mainly internalized energy- temperature-dependent endocytic process, though contribution diffusion component cannot be discarded.
