Summary: The study identified distinct responses of cells to AgNPs and Ag+. AgNPs induce cell death through lipid peroxidation leading to proteotoxicity and necrotic cell death, while Ag+ triggers oxidative stress and apoptotic cell death by increasing H2O2 levels. The mechanism by which AgNPs kill mammalian cells was found to be independent of the contribution of Ag+ released in extracellular media.

Summary: This study focuses on the impact of nanomaterials on microorganisms and plants, specifically examining the effects of size and concentration. Microorganisms were found to be highly susceptible to nanomaterials, while plants showed a hormetic response tied to nanomaterial concentration. The complex responses observed in both microorganisms and plants underscore the importance of considering the physical and chemical characteristics of nanomaterials, as well as the specific biological species involved and the environmental conditions in which they interact.

Summary: This study investigated the effects of silver nanoparticles and zinc oxide nanoparticles on zebrafish embryos in aquatic environments. The research found that spiking these nanoparticles into natural water samples had a toxic effect on the embryos, with the level of toxicity influenced by complex components in the water. Additionally, zinc oxide nanoparticles caused a delay in embryo hatching. Measurement of reactive oxidative stress levels, apoptosis, and autophagy revealed the interaction and toxicity mechanisms of the nanoparticles with the embryos.

Summary: This study investigated the detoxification mechanisms of red clover seedlings exposed to silver ions (Ag+) and found that the growth and physiological metabolism of the plants were disturbed. The research revealed that red clover seedlings initially transformed and immobilized Ag+ in the culture medium, and then transported and fixed them inside the cells, mainly in the form of unreduced Ag+ bound to biological molecules. Additionally, some Ag+ was reduced and formed crystalline silver nanoparticles. The results of this study provide valuable insights into the defense and tolerance mechanisms of red clover to Ag+ and the existing forms of Ag+ in vivo and in vitro.

Summary: The use of nanoscale materials for biomedical applications has raised concerns about their toxic effects on human health. This systematic review focuses on the reproductive toxicity of different types of inorganic nanoparticles in male rodents. The findings indicate that these nanoparticles can cause structural and functional alterations in testicular cells, leading to oxidative stress, apoptosis, and/or necrosis. However, the lack of standardized protocols in the studies results in highly variable outcomes.

Summary: This study found that citrate-coated silver nanoparticles (cit-AgNPs) have bactericidal effects on metal-sensitive bacterial strains under denitrifying conditions, and nitrite has the ability to oxidize these nanoparticles. Additionally, it was observed that AgNPs and Ag(I) may induce different toxicity modes to prokaryotes, highlighting the importance of evaluating the potential ecological toxicity and risks associated with the transformation of nanomaterials.

Summary: The study revealed that only a small percentage of the inhaled silver nanoparticles reached the lungs, with most likely remaining in the upper respiratory tract. The nanoparticles that entered the liver and gastrointestinal tract from the lungs suggested a certain ingestion of silver nanoparticles. Additionally, the presence of silver nanoparticles in the blood and extrapulmonary organs indicated a small fraction entering the systemic circulation via direct translocation from the respiratory tract.

Summary: Submerged macrophytes have developed the ability to use bicarbonate to mitigate the effects of photorespiration, leading to increased oxygen production. Experiments have shown that inhibiting bicarbonate use with a carbonic anhydrase inhibitor significantly reduces oxygen production rate in three out of four studied submerged macrophytes, while the species that solely use CO2 are not affected.

Summary: This study investigated the variations in morphology, anatomy, physiology, and biochemistry between the floating and submerged leaves of the heteroblastic plant Ottelia cordata. The results showed that the floating leaf developed stomate for atmospheric CO2 absorption, while the submerged leaf showed longer, narrower, and thinner characteristics to maximize inorganic carbon uptake underwater. The study also revealed that the submerged leaf could perform C4 metabolism, while the floating leaves only carried on C3 metabolism.

Summary: The acclimation of O. ovalifolia to submerged and aerial environments involves changes in leaf morphology, physiology, and biochemistry. Submerged leaves are longer, narrower, and thinner, increasing their surface area and facilitating carbon absorption underwater. Floating leaves adapt to the aerial environment by directly absorbing atmospheric CO2 through stomata. Both leaf types can utilize bicarbonate, but submerged leaves have a stronger capacity. The adaptation of photosynthesis to different environments relies on changes in photosynthetic pigments and the ability to perform C4 metabolism.
