    Preparation and Application of Single‐Atom Cobalt Catalysts in Organic Synthesis and Environmental Remediation
    Wiley ; 2023
    In:  Small Methods
    Details
    In: Small Methods, Wiley
    Abstract: The development of high‐performance catalysts plays a crucial role in facilitating chemical production and reducing environmental contamination. Single‐atom catalysts (SACs), a class of catalysts that bridge the gap between homogeneous and heterogeneous catalysis, have garnered increasing attention because of their unique activity, selectivity, and stability in many pivotal reactions. Meanwhile, the scarcity of precious metal SACs calls for the arrival of cost‐effective SACs. Cobalt, as a common non‐noble metal, possesses tremendous potential in the field of single‐atom catalysis. Despite their potential, reviews about single‐atom Co catalysts (Co‐SACs) are lacking. Accordingly, this review thoroughly summarized various preparation methodologies of Co‐SACs, particularly pyrolysis; its application in the specific domain of organic synthesis and environmental remediation is discussed as well. The structure–activity relationship and potential catalytic mechanism of Co‐SACs are elucidated through some representative reactions. The imminent challenges and development prospects of Co‐SACs are discussed in detail. The findings and insights provided herein can guide further exploration and development in this charming area of catalyst design, leading to the realization of efficient and sustainable catalytic processes.

    IL‐22 produced by Th22 cells aggravates atherosclerosis development in ApoE −/− mice by enhancing DC‐induced Th17 cell proliferation
    Wiley ; 2020

    Abstract: Th22 cells are a novel subset of CD4 + T cells that primarily mediate biological effects through IL‐22, with both Th22 cells and IL‐22 being closely associated with multiple autoimmune and chronic inflammatory diseases. In this study, we investigated whether and how Th22 cells affect atherosclerosis. ApoE −/− mice and age‐matched C57BL/6J mice were fed a Western diet for 0, 4, 8 or 12 weeks. The results of dynamic analyses showed that Th22 cells, which secrete the majority of IL‐22 among the known CD4 + cells, play a major role in atherosclerosis. ApoE −/− mice fed a Western diet for 12 weeks and administered recombinant mouse IL‐22 (rIL‐22) developed substantially larger plaques in both the aorta and aortic root and higher levels of CD3 + T cells, CD68 + macrophages, collagen, IL‐6, Th17 cells, dendritic cells (DCs) and pSTAT3 but lower smooth muscle cell (SMC) α‐actin expression than the control mice. Treatment with a neutralizing anti–IL‐22 monoclonal antibody (IL‐22 mAb) reversed the above effects. Bone marrow‐derived DCs exhibited increased differentiation into mature DCs following rIL‐22 and ox‐LDL stimulation. IL‐17 and pSTAT3 were up‐regulated after stimulation with IL‐22 and ox‐LDL in cells cocultured with CD4 + T cells and mature DC supernatant, but this up‐regulation was significantly inhibited by IL‐6mAb or the cell‐permeable STAT3 inhibitor S31‐201. Thus, Th22 cell‐derived IL‐22 aggravates atherosclerosis development through a mechanism that is associated with IL‐6/STAT3 activation, DC‐induced Th17 cell proliferation and IL‐22–stimulated SMC dedifferentiation into a synthetic phenotype.

    Identification of amniotic fluid metabolomic and placental transcriptomic changes associated with abnormal development of cloned pig fetuses

    Abstract: Piglets cloned by somatic cell nuclear transfer (SCNT) show a high incidence of malformations and a high death rate during the perinatal period. To investigate the underlying mechanisms for abnormal development of cloned pig fetuses, we compared body weight, amniotic fluid (AF) metabolome, and placental transcriptome between SCNT‐ and artificial insemination (AI)‐derived pig fetuses. Results showed that the body weight of SCNT pig fetuses was significantly lower than that of AI pig fetuses. The identified differential metabolites between the two groups of AF were mainly involved in bile acids and steroid hormones. The levels of all detected bile acids in SCNT AF were significantly higher than those in AI AF. The increase in the AF bile acid levels in SCNT fetuses was linked with the downregulation of placental bile acid transporter expression and the abnormal development of placental folds (PFs), both of which negatively affected the transfer of bile acids from AF across the placenta into the mother’s circulation. Alteration in the AF steroid hormone levels in cloned fetuses was associated with decreased expression of enzymes responsible for steroid hormone biosynthesis in the placenta. In conclusion, cloned pig fetuses undergo abnormal intrauterine development associated with alteration of bile acid and steroid hormone levels in AF, which may be due to the poor development of PFs and the erroneous expression of bile acid transporters and enzymes responsible for steroid hormone biosynthesis in the placentas.

    Phenolics, Antioxidant Activity, and In Vitro Starch Digestibility of Extruded Brown Rice Influenced by Choerospondias axillaris Fruit Peels Addition

    In: Starch - Stärke, Wiley, Vol. 71, No. 9-10 ( 2019-09)
    Abstract: This study investigates the physicochemical properties of extruded brown rice with addition of 1–10% Choerospondias axillari s fruit peels (CFP). The phenolics, flavonoids, and antioxidant activity of extrudates are positively correlated with CFP addition ( r  = 0.996–0.999), and they are significantly increased by 1.1–3.9 fold after 10% CFP addition. In addition, CFP addition significantly increases the water absorption index and alters the pasting profile of extrudates. Furthermore, the CFP addition causes a significant change in the in vitro starch digestibility of extrudates. For instance, the expected glycemic index of extruded brown rice significantly decreases from around 90.8 to 79.8 when 1% CFP is incorporated, while it is not significantly different at higher CFP addition. These results suggest that incorporation of this fruit byproduct into extruded brown rice may improve its nutritional profile, antioxidant activity, and glycemic response.

    Effects of Co‐Addition of Plant Peptides and Lauric Acid on the Physicochemical Properties and In Vitro Digestibility of Sweet Potato Starch
    Wiley ; 2023
    In:  Starch - Stärke Vol. 75, No. 7-8 ( 2023-07)

    In: Starch - Stärke, Wiley, Vol. 75, No. 7-8 ( 2023-07)
    Abstract: The effects of co‐addition of three plant peptides (P)—soybean peptide (SP), wheat peptide (WP) or corn peptide (CP), and lauric acid (LA)—on the physicochemical properties and in vitro digestibility of sweet potato starch (SPS) are investigated. The enthalpy (Δ H 2 ), complex index (CI), ordered crystalline structure, and resistant starch (RS) content of the SPS–LA–P ternary system significantly increase, compared to those of the SPS–P and SPS–LA binary systems. The microscopic surface is smoother and denser, and the cross‐sectional gel layer is thicker. The peak viscosity, breakdown value, paste clarity, and gel hardness of the ternary system also significantly decrease, likely due to the formation of more SPS–LA binary complexes and SPS–LA–P ternary complexes in the ternary systems. The co‐addition of WP and LA demonstrates the most significant increase in the Δ H 2 (1.48 J g −1 ), CI (48.74%), relative crystallinity (18.17%), and molecular orderliness of SPS–control, which also has reduced paste clarity (23.93%). The addition of SP and LA is most effective in reducing the peak viscosity (4183.33 cP) and gel hardness (221.72 g) of SPS, and the ternary systems containing WP and CP have the highest RS content of 29.81% and 28.74%, respectively.
