Summary: Selenium is an essential element for living systems, but becomes toxic at higher concentrations. This study exposed Dunaliella salina cells to different selenium concentrations and found that 50 mg/L selenium had no significant effect on cell growth and selenium accumulation. However, higher selenium levels led to a decrease in photosynthetic efficiency, chlorophyll content, and an increase in reactive oxygen species, proline content, and lipid peroxidation. Superoxide dismutase and catalase played important roles in antioxidative defense. The accumulation of carotenoids varied at different selenium concentrations, and exposure to 200 mg/L selenium resulted in organelle disorganization. Therefore, the selenium-enriched biomass obtained at 50 mg/L could be used for biofortification of food and feed.

Summary: The study demonstrated that the deferiprone-resveratrol hybrid exhibited a more potent inhibitory effect on malaria parasite growth, improved anemia and liver damage in infected mice, and had lower levels of lipid peroxidation products compared to deferiprone alone. The anti-malarial activity of the deferiprone-resveratrol hybrid was associated with anti-RBC hemolysis and liver weight index. Deferiprone-resveratrol hybrid showed anti-plasmodium, anti-hemolysis, and anti-lipid peroxidation activities more effectively than deferiprone in P. berghei-infected mice.

Summary: Cyanobacterial harmful algal blooms are a global issue that negatively impacts the aquatic environment and human health. This study discovered that the bacterium Stenotrophomonas sp. KT48 exhibited strong algicidal activity against Microcystis aeruginosa, a type of cyanobacteria. The algicidal activity was mainly attributed to direct attack on M. aeruginosa cells, rather than the excretion of algicides. Additionally, the study found that the bacterium increased the production of reactive oxygen species and lipid peroxidation in the algal cells, leading to inhibition of the antioxidant system. These findings provide insights into the potential use of strain KT48 as a bacterial agent for the control of cyanobacterial blooms.

Summary: Camelthorn plants show high tolerance to Cd toxicity and have the potential to be used in phytoremediation of Cd-contaminated soils. They can tolerate Cd concentrations up to 200 mg/kg in soil and possess antioxidant defense mechanisms against Cd-induced oxidative stress. With low root-shoot transfer of Cd, Camelthorn plants are suitable for phytostabilization technology and have great potential for remediation of Cd-contaminated soil.

Summary: In a natural environment, interactions of toxic mixtures may lead to diverse biochemical pathways and toxicological responses in aquatic organisms. The study found that exposure to Cd resulted in significant toxicity to mussels, and the addition of Bap at a higher dose accentuated the toxicity by inhibiting metallothionein synthesis. These findings offer insights into the mechanisms of combined xenobiotics in molluscs.

Summary: Contamination by heavy metals has had a severe negative impact on agricultural productivity worldwide. Cadmium (Cd) is particularly detrimental to plants, but applying melatonin (ME), a stress-relief hormone, has been found to mitigate the phytotoxic effects of heavy metals. This study explores how ME reduces damage caused by Cd in strawberry seedlings, and the results demonstrate its potential to improve growth, photosynthesis, redox homeostasis, and secondary metabolites in the plants.

Summary: This study aimed to investigate the protective role of vitamin E in improving cardiotoxicity induced by cyclophosphamide in rats. The results showed that vitamin E could attenuate the elevation of cardiac markers, increase in lipid profiles, reduction in antioxidant enzyme activities, and increase in lipid peroxidation. In addition, vitamin E was found to improve the histopathological alterations caused by cyclophosphamide.

Summary: This study investigated the effects of different soil pH levels on the growth and development of blueberry cultivars. It was found that high soil pH hindered green color development in blueberry leaves and inhibited plant growth. However, different cultivars showed tolerance to high soil pH, with a threshold of pH 6.5. Antioxidant enzyme activities and leaf SPAD values were closely related to blueberry growth and dry matter accumulation, and served as important indicators for assessing blueberry adaptation to high soil pH environments.

Summary: This study provides new insights into the mechanisms of cadmium-induced toxicity in zebrafish larvae and the potential role of zinc in reversing these harmful effects. The results suggest that cadmium interferes with zinc metabolism, leading to its depletion and oxidative stress. However, supplementation of zinc can partially reverse the toxic effects of cadmium, possibly through its interaction with the toxic metal and improvement of oxidative status.

Summary: This study evaluated the effects of different size microplastics present in water bottles on human mesenchymal stromal cells. The results showed that microplastic treatments led to a decrease in cell proliferation, altered differentiation potential, and loss of osteocyte phenotype. This indicates that environmental microplastics can be bioavailable for cell uptake and may result in irreversible diseases.

Summary: This study investigates the application of cyanobacterial extracellular polymeric substances (EPS) as a sensor coating material for microplastic detection. The EPS-based sensor deposited on a gold electrode was analyzed using electrochemical impedance spectroscopy. Surface properties of the sensor were examined using various techniques, including scanning electron microscopy, Fourier transforms infrared spectroscopy, and X-ray spectroscopy. The results show that the EPS-based sensor has a high homogenous structure and can detect low concentrations of four types of microplastics.

Summary: The study developed and characterized new heavy metal sensors using extracellular polymeric substances (EPSs) from a thermophilic microalga strain. The sensors showed a homogeneous character and a lamellar arrangement, and successfully detected cadmium and mercury in a concentration range of 10(-10) M to 10(-4) M using electrochemical impedance spectroscopy and acoustic wave sensing. The results highlight the potential of microalgae EPSs as a sensitive coating material for heavy metal detection, but further investigation is needed for its selectivity in the presence of other compounds.

Summary: Zinc is a powerful immunomodulatory trace element that is closely associated with changes in immune functions and viral infections. It is important to control the amount of zinc in the diet, especially for populations at risk of zinc deficiency. Recently, scientists have developed new methods to treat zinc deficiency and improve zinc bioavailability through techniques like micro- and nano-encapsulation.
