Li, Xiaokang published the artcileIdentifying the Phytotoxicity and Defense Mechanisms Associated with Graphene-Based Nanomaterials by Integrating Multiomics and Regular Analysis, Formula: C4H6O5, the main research area is phytotoxicity graphene nanomaterial metabolomic proteomic; defense; graphene; metabolomics; nanotoxicity; photosynthesis; proteomics.

The application of graphene-based nanomaterials (GBNs) has attracted global attention in various fields, and understanding defense mechanisms against the phytotoxicity of GBNs is crucial for assessing their environmental risks and safe-by-design. However, the related information is lacking, especially for edible vegetable crops. In the present study, GBNs (0.25, 2.5, and 25 mg/kg plant fresh weight) were injected into the stems of pepper plants. The results showed that the plant defense was regulated by reducing the calcium content by 21.7-48.3%, intercellular CO2 concentration by 12.0-35.2%, transpiration rate by 8.7-40.2%, and stomatal conductance by 16.9-50.5%. The defense pathways of plants in response to stress were further verified by the downregulation of endocytosis and transmembrane transport proteins, leading to a decrease in the nanomaterial uptake. The phytohormone gibberellin and abscisic acid receptor PYL8 were upregulated, indicating the activation of defense systems. However, reduced graphene oxide and graphene oxide quantum dots trigger stronger oxidative stress (e.g., H2O2 and malondialdehyde) than graphene oxide in fruits due to the breakdown of antioxidant defense systems (e.g., cytochrome P 450 86A22 and P 450 77A1). Both nontargeted proteomics and metabolomics consistently demonstrated that the downregulation of carbohydrate and upregulation of amino acid metabolism were the main mechanisms underlying the phytotoxicity and defense mechanisms, resp.

Wang, Xiaojun published the artcileCharacterization of odor-active compounds in high-salt liquid-state soy sauce after cooking, SDS of cas: 505-10-2, the main research area is soy sauce odor cooking food processing; Aroma extract dilution analysis; Cooking; Odor-active compound; Sensory evaluation; Soy sauce.

GC x GC-O-MS was used for the aroma extract dilution anal. of cooked high-salt liquid-state soy sauce (HLS), wherein a number of components exhibited high flavor dilution (FD) factors. Electronic nose anal. showed that the heating temperature had a greater influence on the odor characteristics of soy sauce than the heating time. Sensory evaluation and the FD factor of odor-active compounds suggested that the caramel-like/sweet, roasted/roasted nut-like and spicy/burnt odor intensities of the boiled soy sauce were stronger than following heating at a higher temperature These results indicate that different heating conditions could change the intensities of caramel-like/sweet, roasted/roasted nut-like and spicy/burnt in soy sauce during cooking by the concentrations changing of corresponding odor-active compounds This study can provide basic data for the application of HLS aroma in food processing, and provides a reference for the application of HLS aroma in daily cooking and diet.

Wang, Yunpeng published the artcileBioinspired Construction of Artifcial Cardiac Muscles Based on Liquid Crystal Elastomer Fibers, Name: Pentaerythritol tetra(3-mercaptopropionate), the main research area is artificial cardiac muscle liquid crystal elastomer fiber arterial blood.

Human muscles, including skeletal, smooth, and cardiac muscles, are able to perform diverse deformations and execute complex biofunctions stimulated by nerve signals. Similarly, liquid crystal elastomer (LCE), which can respond to external stimuli with large and reversible deformations, demonstrates superior advantages to mimic nature muscles to fabricate artifcial muscles. Till now, LCE has been utilized to simulate deformations and related functions of skeletal and smooth muscles. However, limited by the existing fabrication strategy, employing LCE to mimic the motion of cardiac muscles and further realizing the structure-determined pumping functions, is still an open challenge. Learning from the specifc spatial arrangements and synergistic actuation of cardiac muscle fibers within human heart, a simple and general strategy to construct artifcial cardiac muscles with LCE fbers is proposed. In this work, LCE fbers with similar modulus and actuation behavior to muscle fibers are fabricated and spatially arranged in biol. architectures as cardiac muscle fibers. As a result, artifcial cardiac muscles are constructed and are able to perform simultaneous contraction and torsion motions, realizing heart-pumping functions. This general strategy should be also applicable for other smart materials to conduct challenging tasks.

Barros, Kallyne A. published the artcileDiurnal patterns of growth and transient reserves of sink and source tissues are affected by cold nights in barley, Safety of (S)-2-hydroxysuccinic acid, the main research area is Hordeum diurnal pattern growth cold night malate carbon; EARLY FLOWERING 3; barley growth; carbon metabolism; circadian clock; cold; diurnal metabolism; fructans; malate; starch; sucrose.

Barley is described to mostly use sucrose for night carbon requirements. To understand how the transient carbon is accumulated and utilized in response to cold, barley plants were grown in a combination of cold days and/or nights. Both daytime and night cold reduced growth. Sucrose was the main carbohydrate supplying growth at night, representing 50-60% of the carbon consumed. Under warm days and nights, starch was the second contributor with 26% and malate the third with 15%. Under cold nights, the contribution of starch was severely reduced, due to an inhibition of its synthesis, including under warm days, and malate was the second contributor to C requirements with 24-28% of the total amount of carbon consumed. We propose that malate plays a critical role as an alternative carbon source to sucrose and starch in barley. Hexoses, malate, and sucrose mobilization and starch accumulation were affected in barley elf3 clock mutants, suggesting a clock regulation of their metabolism, without affecting growth and photosynthesis however. Altogether, our data suggest that the mobilization of sucrose and malate and/or barley growth machinery are sensitive to cold.

Gerber, Lucie published the artcileImproved mitochondrial function in salmon (Salmo salar) following high temperature acclimation suggests that there are cracks in the proverbial ‘ceiling’, Application In Synthesis of 97-67-6, the main research area is reactive oxygen species oxidative stress energy metabolism Salmo.

Mitochondrial function can provide key insights into how fish will respond to climate change, due to its important role in heart performance, energy metabolism and oxidative stress. However, whether warm acclimation can maintain or improve the energetic status of the fish heart when exposed to short-term heat stress is not well understood. We acclimated Atlantic salmon, a highly aerobic eurythermal species, to 12 and 20°C, then measured cardiac mitochondrial functionality and integrity at 20°C and at 24, 26 and 28°C (this species’ critical thermal maximum ± 2°C). Acclimation to 20°C vs. 12°C enhanced many aspects of mitochondrial respiratory capacity and efficiency up to 24°C, and preserved outer mitochondrial membrane integrity up to 26°C. Further, reactive oxygen species (ROS) production was dramatically decreased at all temperatures These data suggest that salmon acclimated to ‘normal’ maximum summer temperatures are capable of surviving all but the most extreme ocean heat waves, and that there is no ‘tradeoff’ in heart mitochondrial function when Atlantic salmon are acclimated to high temperatures (i.e., increased oxidative phosphorylation does not result in heightened ROS production). This study suggests that fish species may show quite different acclimatory responses when exposed to prolonged high temperatures, and thus, susceptibility to climate warming.
