Summary: The impacts of freeze-thaw cycles and cooking on the composition and properties of chicken breasts were investigated. Freeze-thaw cycles led to decreased moisture and protein content, as well as increased oxidation and formation of AGEs. Cooking further increased the formation of AGEs, and their levels were correlated with carbonyl and TBARS content. These findings highlight the importance of considering freeze-thaw cycles and cooking in determining the levels of AGEs in cooked meat.

Summary: This study investigated the impact of freeze-thaw cycles on the digestive and protein structural properties of chicken breasts during in vitro digestion. The results showed that with an increase in freeze-thaw cycles, the hardness, chewiness, and shear force of chicken breasts increased, while digestibility decreased and particle size increased. The study also confirmed that freeze-thaw cycles led to the disruption of protein structure and induced protein aggregation.

Summary: This study simulates the effects of freeze-thaw weathering on sand and gravel materials through cycling tests. The study finds that the equivalent diameter and fractal dimension show a strong correlation with long-term strength, while roundness, aspect ratio, and ellipticity show weak correlation. Hence, improving the morphological characteristics of sand and gravel materials can enhance their resistance to freeze-thaw damage in engineering applications.

Summary: This study investigated the effect of low voltage electrostatic field (LVEF) on the oxidative denaturation of myofibrillar proteins (MPs) in repeatedly freeze-thaw (F-T) lamb. F-T cycles intensified MP oxidative denaturation and structural destruction, with the influences becoming more severe after multiple cycles. Samples treated with LVEF-assisted F-T cycles (LFT) showed lower carbonyl/dityrosine content and surface hydrophobicity, higher sulfhydryl content and solubility, and improved activity and structural properties compared to common F-T cycles (CFT). Although the effectiveness of LVEF in suppressing protein oxidation decreased with more F-T cycles, it remained significant compared to samples without LVEF treatment. These findings provide theoretical evidence for the use of LVEF in freezing, storing, and transporting frozen meat.

Summary: Climate change in Arctic landscapes can increase the frequency of freeze-thaw cycles in the active layer and newly thawed permafrost. These cycles can disrupt the soil pore network, affecting water transport, redox conditions, and microbial activity. This study investigates the impact of freeze-thaw cycles on the pore network of thawed permafrost aggregates, revealing changes in pore morphology, connectivity, and throat diameter distribution. The results suggest that freeze-thaw alters the microenvironment of permafrost aggregates and affects soil properties and function in Arctic landscapes undergoing transition.

Summary: This study investigated the frost resistance and fracture behaviors of dredged sand concrete. The results showed that mass loss increased and relative dynamic elastic modulus and compressive strength decreased with an increase in freeze-thaw cycles. The pore structure of concrete was improved with an increase in dredged sand content, leading to improved fracture behavior and frost resistance. Additionally, the fracture surface became rougher with an increase in freeze-thaw cycles. The content of dredged sand influenced the fracture energy, with greater content resulting in higher fracture energy. The accumulation of AE counts, AE energy, and AE b-value reflected the failure process of dredged sand concrete, and a damage model based on AE events obeyed Weibull distribution.

Summary: This study investigates the effects of freeze-thaw cycles (FTCs) on the performance of bioretention cells. The results show that FTCs significantly impact the removal efficiency of nitrogen pollutants in bioretention cells, while having minimal effect on phosphorus. Wood chips are found to be more suitable for efficient removal of nitrogen pollutants under FTCs. These experimental findings provide valuable reference for the construction of bioretention cells in cold regions.

Summary: The research aimed to study the impact of freeze-thaw cycles on porcine longissimus protein and lipid oxidation, as well as HAAs and AGEs. After seven cycles, there was an increase in Norharman and Harman, as well as N epsilon-carboxyethyllysine and N epsilon-carboxymethyllysine, while glucose, creatine, and creatinine decreased. The findings suggest that oxidation and the Maillard reaction during freeze-thaw cycles promote the production of HAAs and AGEs in raw pork.

Summary: Severe negative energy balance and high circulating free fatty acids in postpartum cows can impair the quality of oocytes. This study investigated the compositions of energy metabolism-related lipids in plasma and oocytes of cows at different lactation stages under intensive feeding management. The results showed that early postpartum cows had elevated levels of oocyte free fatty acids, indicating a high risk of lipotoxicity. The severe negative energy balance in the previous weeks was closely related to increased oocyte free fatty acid content.

Summary: By analyzing serum samples from 20 patients with Kawasaki disease, it was found that lysophosphatidylcholine (LPC) and lysophosphatidylethanolamine (LPE) were decreased in the IVIG-resistant group before treatment, suggesting their potential as markers for diagnosing IVIG resistance. During treatment, the lipidomic changes were weaker in the IVIG-resistant group. After treatment, LPC and LPE species were lower in the IVIG-resistant group and negatively correlated with inflammatory markers, indicating the potential association between lipid metabolism and IVIG sensitivity/resistance in Kawasaki disease.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
