Nanoplastics (NPs) affect fertility. We evaluated the effects of NPs treatment on luteal and endothelial cells. We examined crucial markers of growth and redox status. NPs treatment did not induce changes in ATP levels in luteal cells, while it increased (p< 0.05) their proliferation. In endothelial cells, no change in proliferation was detected, while an increase (p<0.05) in ATP levels was observed. The increase of reactive oxygen species, superoxide anion (p<0.05) and nitric oxide (p<0.001) was detected in both cell types, which also showed changes in superoxide dismutase enzyme activity as well as an increase of non-enzymatic antioxidant power (p<0.05). A decrease (p<0.05) in progesterone production as well as an increase of vascular endothelial growth factor A levels were detected (p<0.05). In addition, a dose-dependent accumulation of NPs in endothelial cells was shown, that likely occurred through adhesion and internalization. Results underline potential risk of NPs for corpus luteum functionality.

Dye-laden wastewater poses a significant environmental and health threat. This study investigated the potential of green-synthesized zinc oxide nanoparticles (ZnO NPs), derived from Padina pavonica brown algae extract, for the removal of methylene blue (MB) dye. The hypothesis was that utilizing algal extract for ZnO NP synthesis would enhance adsorption capacity and photocatalytic activity for dye removal.

Developing multimodal combination therapy strategies to disrupt the redox homeostasis within tumor cells is currently an important approach in cancer treatment. In this study, we designed and prepared multifunctional composite nanoparticles MPDA-PEG@MnO@2-DG (MPPMD NPs) utilizing mesoporous polydopamine nanoparticles (MPDA NPs) as carriers. These carriers were coated with polyethylene glycol (PEG), and manganese dioxide (MnO) and loaded with 2-deoxy-d-glucose (2-DG).

Optimizing the design of nanoparticulate co-delivery systems of antigens and immunomodulators to induce antigen-specific immune tolerance effectively remains a challenge, constrained by low drug loading capacity and premature leakage of active ingredients. Here, we report a prodrug self-assembled nanoparticles (NPs) strategy to synergistically deliver antigen and rapamycin (RAPA) into antigen-presenting cells (APCs) by simply conjugating rapamycin with an aliphatic chain. These prodrug NPs can be efficiently taken up by APCs and then release rapamycin through cleavage of the linker by intracellular esterase.

In situ gelling, cell-laden hydrogels hold promise for regenerating tissue lesions with irregular shapes located in complex and hard-to-reach anatomical sites. A notable example is the regeneration of neural tissue lost due to cerebral cavitation. However, hypoxia-induced cell necrosis during the vascularization period imposes a significant challenge to the success of this approach.

Phenol is a highly concerning pollutant in petrochemical industrial wastewater. It is extremely poisonous, carcinogenic, and persistent, therefore, it bioaccumulates in the food chain reaching humans, where it causes acute irritation to the skin, eyes, and respiratory tract, as well as chronic effects on the liver, kidneys, and nervous system. It spills or leaks easily into surface water or groundwater sources, leading to the creation of other harmful substituted compounds.
