Summary: By developing DNAzyme-based fluorescent turn-on sensors, we can selectively visualize either Fe2+ or Fe3+, revealing a decreased Fe3+/Fe2+ ratio during ferroptosis and an increased Fe3+/Fe2+ ratio in Alzheimer's disease mouse brain. The elevated Fe3+/Fe2+ ratio was mainly observed in amyloid plaque regions, suggesting a correlation between amyloid plaques and the accumulation of Fe3+ and/or conversion of Fe2+ to Fe3+. Our sensors can provide deep insights into the biological roles of labile iron redox cycling.

Summary: AA at concentrations of 1 to 50 µmol/L and 1 to 75 µmol/L completely inhibited light emission from Fe2+-EGTA-H2O2 and Fe3+-EGTA-H2O2 systems, respectively. Concentrations of 100 and 200 µmol/L did not affect chemiluminescence of Fe3+-EGTA-H2O2 but tended to increase light emission from Fe2+-EGTA-H2O2. DHAA at concentrations of 1 to 100 µmol/L had no effect on chemiluminescence of both systems.

Summary: In this study, Fe-embedded Ni-based MOFs with heteroatomic metal nodes were successfully prepared and utilized for persulfate activation. The accelerated Fe3+/Fe2+ redox cycle in the FeNi-MOFs under light irradiation promoted the recovery of Fe2+ with a cycling efficiency of over 58%.

Summary: Smart theragnostic nanoplatforms show great potential in clinical tumor treatment by utilizing the Fe-based Fenton reaction to generate reactive oxygen species in tumor sites. An efficient enzymatic/Fenton-starvation nanoreactor PMs (PGPMs) has been developed to overcome obstacles like low H2O2 concentration, weak acidicity of tumor tissue, and low catalytic activity of conventional Fenton reagents. PGPMs demonstrate tumor microenvironment-responsive behavior, enhanced catalytic activity, and capabilities for ultrasound and MR imaging in both in vitro and in vivo studies, showing promise for diagnostic and therapeutic applications in tumor treatment.

Summary: This study reports a new type of MOF (m-MIL-101-1.0) with both interior linker and metal valence modulation, which enhances photocatalytic activity by facilitating charge transfer. The unique structure provides both internal and external charge transfer channels, leading to improved activity compared to traditional MOFs. This interior configuration has the potential to tune the activity of MOFs and expand the applications of MOF-based photocatalysts.

Summary: A simple electrochemical sensor for ascorbic acid was developed based on the charge transfer synergy improvements of Ni-SnO2. The Ni-SnO2 nanocomposite was synthesized using the hydrothermal technique and confirmed through various analysis methods. The Ni-SnO2-modified conductive fabric electrode showed a linear response to ascorbic acid and could be used to measure ascorbic acid in human sweat samples.

Summary: Transition metal ions play crucial roles in medicine, life sciences, and environmental science, but some like mercury, copper, and iron ions pose serious health and environmental risks due to biomagnification. Monitoring metal ion levels in organisms and the environment is urgent, and reaction-based fluorescent probes offer higher sensitivity and selectivity than traditional methods. Research on these probes for Hg2+, Cu2+, and Fe2+/Fe2+ detection has advanced in the past decade, with potential for interdisciplinary development in the future.

Summary: The carbon paste electrode modified with the MIL-101(Cr) metal-organic framework showed improved charge transfer ability and increased real surface area, resulting in a more intense oxidation peak current of sulfite ions compared to the unmodified electrode. A linear relationship between the oxidation peak current and sulfite concentration was established, with a detection limit of 0.58 μM in the range of 2 μM-70 μM.

Summary: This study investigated the possibility and mechanism of using biochar to accelerate the Fe3+/Fe2+ cycle to improve the efficiency of Fe3+/persulfate catalytic oxidation. It was found that medium-temperature derived biochar had the greatest ability to enhance the Fenton-like system compared to low and high-temperature biochar. The results also showed that the generation of radicals increased and then decreased with decreasing pyrolysis temperature.

Summary: This study measured the UV/Vis/NIR absorption spectra of different composition garnets and identified a broad absorption band assigned to an IVCT mechanism. This mechanism, commonly observed in iron minerals, was not previously observed in garnets. The IVCT mechanism in garnets is influenced by composition and growth conditions.

Summary: Nanozymes like CuO NP-POM have been developed with tetraenzyme mimetic activities for the construction of colorimetric and fluorometric sensors with high detection sensitivity for specific targets such as ascorbic acid and Fe2+. These sensors have been successfully applied in detecting AA and Fe2+ in food and biological samples, offering rapid detection methods for specific analysis. This work not only enhances the multi-nanozyme activity of nanocomposites, but also provides a pathway for the rapid analysis of specific targets using special nanozyme activities.

Summary: The study found that fruit size and weight decrease during cold storage, respiration rate and color variables differ between different maturity stages, and levels of soluble carbohydrates and organic acids vary with fruit maturity. Most amino acids decrease during cold storage, but some increase in 100% mature fruits.

Summary: Cupuassu fruit was spray dried using inulin/maltodextrin mixtures as wall material in order to preserve its nutritional value and antioxidant activity. The optimal process conditions were determined using response surface methodology, and the microencapsulates obtained had a smooth surface and released 76.7% of ascorbic acid under simulated intestinal fluid conditions. These results suggest the potential of cupuassu microencapsulates as a strategy for valorizing Amazonian fruits.

Summary: The study found that digested berry extracts improved cell survival in stressed yeast cells, highlighting the importance of anthocyanin types and levels, as well as gastrointestinal digestion processes for cellular defense. Anthocyanins appear to protect cells by inducing a cellular defense system rather than through a direct antioxidative effect on H2O2.

Summary: Higher proportions of n-6 polyunsaturated fatty acids (including arachidonic acid) but lower proportions of n-3 polyunsaturated fatty acids (including DPA) in the infant's phospholipids at birth were associated with an increased risk of atopic eczema at 12 months of age. The n-6 and n-3 PUFAs were related to maternal intake of meat and fish, respectively. Our results suggest that prenatal exposure to unsaturated fatty acids is associated with eczema development in the infant. Maternal diet during pregnancy may partly explain the fatty acid profiles in utero.

Summary: The proportion of arterial and venous cord blood affects the monitoring results of neonate health. Metabolomics analysis reveals differences in the metabolomes of arterial and venous blood, mainly related to amino acid and energy metabolism. Venous cord metabolites related to energy metabolism are positively associated with multiple pregnancies.

Summary: This study compared the absorption of non-heme iron from meals containing texturized fava bean protein, beef protein, and cod protein. The results showed that iron absorption from fava bean protein meal was significantly lower compared to beef protein meal and cod protein meal. Therefore, a dietary shift from meat and fish protein to fava bean protein may increase the risk of iron deficiency.

Summary: Studies suggest that early-life exposure to toxic metals and fluoride may affect the immune system and contribute to allergic diseases. This study investigated the relationship between exposure to these compounds in pregnant women and their infants with food allergy and atopic eczema. The results showed that gestational cadmium exposure was associated with an increased risk of food allergy in infants, while gestational and infant fluoride exposure had a weak association with atopic eczema. Further research is needed to establish causality.
