Both plastics and CO2 are waste carbon resources, and their accumulation in nature has led to severe environmental pollution. However, simultaneously converting plastic waste and CO2 into value-added chemicals remains a challenge. Here we demonstrate a catalytic reforming process that converts plastics and CO2 into syngas over an electrified FeCrAl heating wire. The temperature of the electrified heating wire can quickly exceed 800 °C, facilitating the decomposition of polyethylene into gaseous hydrocarbons. The high-temperature heating wire promote the CO2 deoxygenation, resulting in the generation of CO, as well as the dehydrogenation of gaseous hydrocarbons. Significantly, the additional O species from CO2 and the carbon species from hydrocarbons can react to form CO, maintaining the high catalytic activity of the electrified heating wire. This novel approach is of paramount to achieving a circular economy in addressing the ongoing environmental crisis caused by the accumulation of plastic waste and excessive CO2 emissions. Simultaneously converting plastic waste and CO2 into value-added chemicals remains a challenge. Here, the authors demonstrate the feasibility of transforming waste plastics and CO2 into H2 and CO by utilizing solar irradiation via a photovoltaic system and an electrified FeCrAl heating wire.

Triglyceride (TAG) deposition in the liver is associated with metabolic disorders. In lower vertebrate, the propensity to accumulate hepatic TAG varies widely among fish species. Diacylglycerol acyltransferases (DGAT1 and DGAT2) are major enzymes for TAG synthesis. Here we show that large yellow croaker (Larimichthys crocea) has significantly higher hepatic TAG level than that in rainbow trout (Oncorhynchus mykiss) fed with same diet. Hepatic expression of DGATs genes in croaker is markedly higher compared with trout under physiological condition. Meanwhile, DGAT1 and DGAT2 in both croaker and trout are required for TAG synthesis and lipid droplet formation in vitro. Furthermore, oleic acid treatment increases DGAT1 expression in croaker hepatocytes rather than in trout and has no significant difference in DGAT2 expression in two fish species. Finally, effects of various transcription factors on croaker and trout DGAT1 promoter are studied. We find that DGAT1 is a target gene of the transcription factor CREBH in croaker rather than in trout. Overall, hepatic expression and transcriptional regulation of DGATs display significant species differences between croaker and trout with distinct hepatic triglyceride deposition, which bring new perspectives on the use of fish models for studying hepatic TAG deposition. Two diacylglycerol acyltransferases were shown to be differently regulated in large yellow croaker and rainbow trout. While DGAT1 is increased upon oleic acid treatment more in croaker than in trout, DGAT2 showed no significant expression difference. [ABSTRACT FROM AUTHOR]

Aquaculture in China has undergone significant evolution in recent decades, transitioning from traditional practices to a vital food production industry. Alongside the rapid growth of aquaculture in China, aquafeed production continues to expand swiftly. This review attempts to establish an overview of the history and achievements in aquaculture nutrition research and feed industry in China. The development of scientific concept and methodology, especially the advanced molecular biology technology guarantees the shift from traditional nutrition to molecular nutrition, and subsequently to precision nutrition in aquaculture nutrition research. This evolution has facilitated the formulation of effective strategies to enhance the growth, health and product quality of aquatic animals. The advancements of aquaculture nutrition research and feed industry have also been propelled by innovative research concepts rooted in principles such as the health and safety of aquatic animals, the quality of aquatic products, resource conservation and environmental friendliness, and the advancements in key processing technologies within the aquafeed industry. The future perspectives of the aquaculture nutrition research and feed industry in China are also proposed. The present work aims to provide a reference for promoting the development of aquaculture nutrition research and feed industry in China. [ABSTRACT FROM AUTHOR]

Angiopoietin-like 4 (ANGPTL4) is a potent regulator of TAG metabolism, but knowledge of the mechanisms underlying ANGPTL4 transcription in response to fatty acids is still limited in teleost. In the current study, we explored the molecular characterisation of ANGPTL4 and regulatory mechanisms of ANGPTL4 in response to fatty acids in large yellow croaker (Larimichthys crocea). Here, croaker angptl4 contained a 1416 bp open reading frame encoding a protein of 471 amino acids with highly conserved 12-amino acid consensus motif. Angptl4 was widely expressed in croaker, with the highest expression in the liver. In vitro , oleic and palmitic acids (OA and PA) treatments strongly increased angptl4 mRNA expression in croaker hepatocytes. Moreover, angptl4 expression was positively regulated by PPAR family (PPAR- α , β and γ), and expression of PPAR γ was also significantly increased in response to OA and PA. Moreover, inhibition of PPAR γ abrogated OA- or PA-induced angptl4 mRNA expression. Beyond that, PA might increase angptl4 expression partly via the insulin signalling. Overall, the expression of ANGPTL4 is strongly upregulated by OA and PA via PPAR γ in the liver of croaker, which contributes to improve the understanding of the regulatory mechanisms of ANGPTL4 in fish.

BACKGROUND [color=black]This study was conducted at a single center and aimed to compare postoperative pain in 70 women with breast cancer following general anesthesia for mastectomy with and without serratus anterior plane (SAP) block.[/color] MATERIAL AND METHODS [color=black]A total of 70 breast cancer patients who met the criteria were randomly divided into the general anesthesia combined with SAP block group (group S) and the general anesthesia only group (group G). Perioperative anesthetic drug dosage, the visual analog scale (VAS) score at different time points, and the patient's satisfaction with analgesia 24 h after surgery, and incidence of postmastectomy pain syndrome (PMPS) were statistically analyzed in the 2 groups.[/color] RESULTS [color=black]Compared with group G, group S had lower intraoperative remifentanil dosages (P=0.003), a lower total amount of sufentanil via analgesia pump during the 24-h postoperative period (P<0.001), and lower VAS scores at 2 h, 4 h, and 8 h after surgery, and the differences were significant (P<0.05). Compared with group G, group S had a shorter first flatus time, got out of bed sooner, had a lower incidence of nausea and vomiting (P<0.05), and lower incidence of PMPS at 3 and 6 months after the operation (P<0.05).[/color] CONCLUSIONS [color=black]At a single center, preoperative SAP block can significantly reduce postoperative pain after modified radical mastectomy for breast cancer.[/color].
