    Abstract To sustain global warming below 2 °C, carbon dioxide emission mitigation has become an extensive worldwide priority. This paper proposes a comprehensive assessment by evaluating the effects of technology transfer, human capital, and renewable energy on carbon dioxide emissions among seven different regions along with the Belt and Road Initiatives from 2008 to 2018. Based on econometric estimations, it is found that human capital, renewable energy, and technology transfer show a negative but significant association with carbon dioxide emissions, indicating that an increase in human capital, renewable energy, and technology transfer can reduce carbon dioxide emissions in the Belt and Road countries. On the other hand, we found a positive and significant relationship between carbon dioxide emissions, economic growth, and foreign direct investment (FDI), indicating that economic growth and foreign direct investment increase carbon emissions. The findings of this study reveal that the adaptation of technology transfer, renewable energy consumption, and human capital are key factors in the reduction of carbon dioxide emissions in the Belt and Road counties. Our findings provide evidence of the social advantages of investing in advanced human capital, renewable energy, and technology transfer suggesting a promising route for devoting climate change without impeding economic growth.

    Abstract This study aims to investigate the relationship between carbon emissions (CO₂) and economic policy uncertainty for East Asian countries. During recent decades, climate change has become a severe issue globally. To our understanding, the impact of economic policy uncertainty (EPU) on CO₂ emissions has not been thoroughly studied in the environment-energy literature. To overcome this research gap, this study explores the link between EPU, CO₂ emissions, foreign direct investment (FDI), and renewable energy for the panel of four East Asian economies, namely, China, Japan, South Korea, and Singapore, from 1997 to 2020. We used second-generation econometric estimations to confirm cross-sectional dependence, cointegration, and stationarity among the selected variables. This study finds that economic policy uncertanity (EPU), trade, and GDP have a positive correlation with carbon emissions. However, FDI and renewable energy consumption boost the quality of the environment of East Asian economies. The outcomes of the Dumitrescu–Hurlin panel causality estimation revealed two-way association between CO₂ and economic policy uncertainty, CO₂ and energy consumption, CO₂ and economic growth, and CO₂ and trade. Afterward, we use the FMOLS estimations for robustness check. Based on the inclusive outcomes, we draw substantial suggestions for decision-makers and urge them to consider the potential negative effects of EPU on CO₂ emissions policies. In addition to this, if policymakers seek to simultaneously control EPU and CO₂ emissions, they should work out for alternate ways such as the use of green technology related to energy, foreign capital investment, and renewable energy consumption to mitigate CO₂ emissions.

    Abstract Objective: Lipoprotein assembly and secretion in the small intestine are critical for dietary fat absorption. Surfeit locus protein 4 (SURF4) serves as a cargo receptor, facilitating the cellular transport of multiple proteins and mediating hepatic lipid secretion in vivo. However, its involvement in intestinal lipid secretion is not fully understood. In this study, we investigated the role of SURF4 in intestinal lipid absorption. Methods: We generated intestine-specific Surf4 knockout mice and characterized the phenotypes. Additionally, we investigated the underlying mechanisms of SURF4 in intestinal lipid secretion using proteomics and cellular models. Results: We unveiled that SURF4 is indispensable for apolipoprotein transport and lipoprotein secretion. Intestine-specific Surf4 knockout mice exhibited ectopic lipid deposition in the small intestine and hypolipidemia. Deletion of SURF4 impeded the transport of apolipoprotein A1 (ApoA1), proline-rich acidic protein 1 (PRAP1), and apolipoprotein B48 (ApoB48) and hindered the assembly and secretion of chylomicrons and high-density lipoproteins. Conclusions: SURF4 emerges as a pivotal regulator of intestinal lipid absorption via mediating the secretion of ApoA1, PRAP1 and ApoB48.

    Abstract Aiming to realize anti-dripping and improve fire retardancy of polyester fabrics, novel hybrid multilayer nano-coatings composed of γ-amino propyltriethoxysilane (KH-550), bio-based betadex sulfobutyl ether sodium (SBE-β-CD) and [(6-Oxido-6H-dibenz-[c,e][1,2]oxaphosphorin-6-yl)methyl] butanedioic acid (DDP), were successfully constructed through layer-by-layer self assembly (LBL) method. Polyacrylic acid (PAA) layer were firstly deposited onto polyester fabrics via UV-grafting, facilitating the following electrostatic adhesion for bi-layer electrolytes. The LBL assembly electrolytes as well as coating thickness were investigated in order to have a better optimization of the nano-coatings with the desired flame resistance properties. The morphological analysis, thermal stability, flame retardant properties of multilayer modified polyester were carried out by scanning electron microscopy (SEM) equipped with an energy dispersive spectrometer (EDS), thermogravimetry analysis (TGA), limiting oxygen index (LOI), UL-94 test, and cone calorimeter test (CCT), respectively. After the functional multilayer coated, the ignition time was delayed. Moreover, total heat release and peak heat release rate were reduced but char residues increased. Of particular significant is the melt dripping phenomena disappearance in optimum condition of (K/S)₆+(K/D)₃ hybrid LBL coatings with LOI value of 36% and V-0 rating in UL-94 test. The analysis of SEM, fourier transform infrared spectrometer (FITR) and X-ray photoelectron spectroscopy (XPS) results of the residual char indicated a compact exterior layer but multicellular structures for interior layer with thermodynamically stability SiO₂, which was served as a barricade shield to protect the underlaying polymer matrix during the combustion process. This suggested that both condensed-phase and gas-phase flame-retardancy made contributions to the flame retardant mechanism. The synergistic effect of hybrid LBL multilayer surface could impart polyester fabrics with high fire retardancy and non-dripping performance.

    Abstract Novel hydrophobic/hydrophilic Janus fibrous membranes, the poly[4,4′-methylenebis (phenylisocyanate)-alt-1,4-butanediol/di(propylene glycol)/plycaprolactone] (PU) fibrous membrane as the hydrophobic layer and cellulose acetate (CA) fibrous membrane as the hydrophilic layer, were fabricated by the so-called “layer-by-layer” electrospinning technology. A series of the PU/CA Janus membranes with different electrospinning time of the CA layers by which the thickness of hydrophilic layer can be controlled were also prepared to uncover its influence on the directional water vapor transmission. The results showed that water vapor transmission capability from the hydrophobic side to the hydrophilic side of the PU/CA Janus fibrous membrane was enhanced rather than that from the reverse direction of the same membrane. The optimal water vapor transmission capacity existed when the electrospinning time of CA fibrous membrane reached 15 min. Such enhanced water vapor transmission originated because of the asymmetric wettability of the Janus membrane and the strong force to draw tiny water droplet from the hydrophobic side to the hydrophilic side. The novel understanding is useful for facile designing and fabrication of efficient moisture permeable fabrics and clothing.

    Abstract Iron deficiency anemia is a common nutritional deficiency disease in women during pregnancy, mainly due to the increased iron requirements of pregnant women and fetuses, resulting in a lack of iron elements necessary for the production of red blood cells, resulting in a decrease in the number of red blood cells and the symptoms of anemia; Causes chronic fetal hypoxia and affects the normal development of some important organs of the fetus. This article explores the clinical value of oral iron drugs combined with diet therapy for maternal anemia. Observed the changes of hemoglobin (Hb), red blood cell count (RBC), average hemoglobin concentration (McHc), serum iron (SI), transferrin saturation (TS) and other indicators of pregnant women before and after treatment and the differences in pregnancy outcomes. Compared with before treatment, the maternal Hb, RBC, McHc, SI, TS and other indicators increased to a certain extent after treatment. Among them, the increase of each indicator in the experimental group is significantly larger than that in the control group. Differences between groups are considered to be meaningful after statistical analysis. (P<0.05). Oral iron drugs combined with diet therapy can effectively improve the symptoms of anemia and have a positive impact on pregnancy outcomes.

    Abstract Summary: Pancreatic development requires spatially and temporally controlled expression of growth factors derived from mesenchyme. Here, we report that in mice the secreted factor Fgf9 is expressed principally by mesenchyme and then mesothelium during early development, then subsequently by both mesothelium and rare epithelial cells by E12.5 and onwards. Global knockout of the Fgf9 gene resulted in the reduction of pancreas and stomach size, as well as complete asplenia. The number of early Pdx1+ pancreatic progenitors was reduced at E10.5, as was proliferation of mesenchyme at E11.5. Although loss of Fgf9 did not interfere with differentiation of later epithelial lineages, single-cell RNA-Sequencing identified transcriptional programs perturbed upon loss of Fgf9 during pancreatic development, including loss of the transcription factor Barx1. Lastly, we identified conserved expression patterns of FGF9 and receptors in human fetal pancreas, suggesting that FGF9 expressed by pancreatic mesenchyme may similarly affect the development of the human pancreas.

    Abstract The low-cost, heavy metal ion (Cu(II)) adsorptive multi-structured nanofibrous membranes of silicon oxide naonoparticles in-situ anchored polyvinylidene fluoride-hexafluoropropylene (SiO 2 @PVDF-HFP) fibers were fabricated by the facile electrospinning technique combined with sol⁻gel strategy. To explore the benefits of the structure-related Cu(II) adsorption capacity, the fiber diameters of SiO 2 @PVDF-HFP nanofibrous membranes were changed which also resulted in the change of their porosity. Taking advantage of the constructed multi-structures and efficient fiber morphology regulation which not only changed the PVDF-HFP nanofibrous membrane from hydrophobic to superhydrophilic but also increased the porosity of the membrane, the SiO 2 @PVDF-HFP nanofibrous membrane with a smaller diameter and a larger porosity exhibits higher Cu(II) adsorption capacity. The adsorption amount was approximate to 21.9 mg per gram of the membrane, which was higher than that of membranes with larger fiber diameter (smaller porosity) and the smooth one. Furthermore, the model isotherms of Freundlich and Langmuir, as well as the kinetic models of pseudo-first-order and pseudo-second-order were preferred to analyze the adsorption equilibrium data. The Freundlich model and the pseudo-first-order were well fitted to the adsorption experimental data. It not only uncovers the structure-related-property of multi-structured nanofibrous membranes, but also provides an efficient and facile way to design heavy metal ion adsorption materials.
