Diatom-inspired hierarchical carbon catalysts advance sustainable water decontamination via electron transfer-driven peroxide activation.

Catalysts for heterogeneous advanced oxidation processes (AOPs) in water remediation face environmental sustainability challenges, due to the intensive production of catalysts and limited stability of catalysts while maintaining high efficiency. Herein, we design a biomimetic carbon catalyst (BCC) inspired by the diatom frustule valve structure, achieving high environmental sustainability while maintaining superior water decontamination performance by a non-radical direct electron transfer (DET) pathway through activating peracetic acid (PAA). Utilizing a hydrogen-bonding strategy, BCC features pillared layered hierarchical pores with an ultrahigh specific surface area of 2710.

Glutathione reductase underlies the stability of mutant p53 by antagonizing protein glutathionylation.

Mutp53 level is widely variable among individual cancer cells in tumor tissues, and within cells a higher level of mutp53 is usually observed in the nucleus as compared to the cytoplasm. This spatial heterogeneity in mutp53 expression has been well documented and likely plays an important role in tumor therapeutic resistance. However, its underlying mechanism remains poorly understood.

Endogenous Proteases in Sea Cucumber (): Deterioration and Prevention during Handling, Processing, and Preservation.

The sea cucumber is an essential nutrient source and a significant economic marine resource associated with successful aquaculture. However, sea cucumbers are highly susceptible to autolysis induced by endogenous protease after postmortem, and the phenomenon of body wall "melting" occurs, which seriously affects the food quality of products and the degree of acceptance by consumers. To satisfy the growing demand for fresh or processed sea cucumbers, we must clarify the autolysis mechanism of sea cucumbers and the methods to achieve autolysis regulation.

Effect of citric acid modification on the properties of hydrochar and pyrochar and their adsorption performance toward methylene blue: crucial roles of minerals and oxygen functional groups.

The adsorption performance toward ciprofloxacin (CIP), a typical antibiotic in waterbodies, was also investigated.

Cryoprotective Effects and Quality Maintenance of Antifreeze Proteins and Peptides on Aquatic Products: A Review.

Aquatic products are gaining popularity due to their delicacy and high nutrient value. However, they are perishable, with a short shelf-life. Frozen storage is associated with adverse effects, leading to protein oxidation and degradation, thereby altering the protein's structural integrity and subsequently influencing the palatability of protein-based food products.

HP-P above 400 MPa decreased heme iron content, while upsurged non-heme iron content. Increasing pressure induced gaps and abnormal hemocyte cell arrangements.

Nutrient Composition and Flavor Profile of Crucian Carp Soup Utilizing Fish Residues through Comminution and Pressure-Conduction Treatment.

In conventional fish soup processing, valuable aquatic resources like fish skins, bones, and scales are often squandered. This study was aimed at investigating if comminution combined with pressure-conduction treatment has the potential to enhance the reutilization of cooking residues. The different blending ratios of original soup (OS), made from the initial cooking of fish, and residue soup (RS), produced from processed leftover fish parts, were alternatively investigated to satisfy the new product development.

Effects of super-chilling storage on shelf-life and quality indicators of Coregonus peled based on proteomics analysis.

The advantages of super-chilling storage at -2 °C for maintaining the quality of Coregonus peled muscle were investigated using the rigor-mortis index (RM), ATP-related compounds, K-value, muscle hardness, impedance measurement, and total viable count. The results indicated that the softening of fish muscle and increase in K-value were substantially suppressed following storage at -2 °C compared to that at 0 °C. In particular, the hardness of fish muscle stored for 6 days at -2 °C was much higher than that of the samples stored for 2 days at 0 °C.

Rigor mortis, ATP-related components, K-value, and hardness of rainbow trout muscle during storage were monitored along with impedance. The results showed that the progress of rigor mortis was accompanied by an increase in impedance.

Low-temperature steaming improves eating quality of whitefish.

In this study, effects of different steaming conditions (temperature-time scales) on quality characteristics of cooked whitefish (Coregonus peled) were characterized to guide product development. Investigation of three cooking conditions, including 60°C (3-20 min) 80°C (1-12 min) and 100°C (1-6 min) indicated that properties including textural properties, cooking loss, color change, water holding capacity (WHC), and protein content were all significantly correlated to the cooking condition. It was observed that the color changes of fish meat, especially the brightness L* were strongly correlated to the relative extraction rate (RER) of myofibrillar proteins (MFPs), which could be considered as a marker for the doneness of the cooked whitefish.
