1Endometrial response to conceptus-derived estrogen and interleukin-1β at the time of implantation in pigs显示文摘The establishment of pregnancy is a complex process that requires a well-coordinated interaction between the implanting conceptus and the maternal uterus. In pigs, the conceptus undergoes dramatic morphological and functional changes at the time of implantation and introduces various factors, including estrogens and cytokines,interleukin-1β2(IL1 B2), interferon-γ(IFNG), and IFN-δ(IFND), into the uterine lumen. In response to ovarian steroid hormones and conceptus-derived factors, the uterine endometrium becomes receptive to the implanting conceptus by changing its expression of cell adhesion molecules, secretory activity, and immune response. Conceptus-derived estrogens act as a signal for maternal recognition of pregnancy by changing the direction of prostaglandin(PG) F2αfrom the uterine vasculature to the uterine lumen. Estrogens also induce the expression of many endometrial genes,including genes related to growth factors, the synthesis and transport of PGs, and immunity. IL1 B2, a pro-inflammatory cytokine, is produced by the elongating conceptus. The direct effect of IL1 B2 on endometrial function is not fully understood. IL1 B activates the expression of endometrial genes, including the genes involved in IL1 B signaling and PG synthesis and transport. In addition, estrogen or IL1 B stimulates endometrial expression of IFN signaling molecules,suggesting that estrogen and IL1 B act cooperatively in priming the endometrial function of conceptus-produced IFNG and IFND that, in turn, modulate endometrial immune response during early pregnancy. This review addresses information about maternal-conceptus interactions with respect to endometrial gene expression in response to conceptus-derived factors, focusing on the roles of estrogen and IL1 B during early pregnancy in pigs.Hakhyun Ka Heewon Seo Yohan Choi Inkyu Yoo Jisoo Han 2018Journal of Animal Science and Biotechnology2018,9,3:5
2Energy-saving strategy for a transport bed flash calcination process applied to magnesite显示文摘A transport bed flash calcination(TBFC)process applied to magnesite is systematically investigated through process simulation to optimize the energy-saving strategy.The high-temperature calciner flue gas is used to preheat the fed magnesite,while the sensible heat with the caustic calcined magnesia(CCM)product is cooled by air sent to the calciner.Pre-decomposition of magnesite during preheating is considered on basis of the kinetics measured using a micro fluidized bed reaction analyzer that allows the minimized effect of external diffusion on reaction.With staged fuel gas supply the TBFC process allows the equivalence ratios around 1.2 for combustion.The preferred arrangement of stages for magnesite preheating and CCM cooling are respectively 4 and 2,leading to the energy consumption of 4100 kJ/kg-CCM and the energy efficiency of 66.8%,which is almost doubly higher than the 33.9%of the conventional reverberatory furnaces(RF).The pre-decomposition occurs mainly in the 1st-stage preheater,and the maximal conversion is about 13%.Varying the stages of preheating appears more influential on the energy saving than varying the cooling stages,while residence time above 1 s in the preheaters has limited effect.Ping An Zhennan Han Kangjun Wang Jiguang Cheng Zhongkai Zhao Yohanes Andre Situmorang Jenny Rizkiana Abuliti Abudula Guoqing Guan 2021Carbon Resources Conversion2021,4,1:1
3TIMP-1 and its potential diagnostic and prognostic value in pulmonary diseases显示文摘Tissue inhibitors of metalloproteases(TIMPs)have caught the attention of many scientists due to their role in various physiological and pathological processes.TIMP-1,2,3,and 4 are known members of the TIMPs family.TIMPs exert their biological effects by,but are not limited to,inhibiting the activity of metalloproteases(MMPs).The balance between MMPs and TIMPs is critical for maintaining homeostasis of the extracellular matrix(ECM),while the imbalance between MMPs and TIMPs can lead to pathological changes,such as cancer.In this re-view,we summarized the current knowledge of TIMP-1 in several pulmonary diseases namely,acute lung injury(ALI)/acute respiratory distress syndrome(ARDS),pneumonia,asthma,chronic obstructive pulmonary disease(COPD),cystic fibrosis,and pulmonary fibrosis.Considering the potential of TIMP-1 serving as a non-invasive di-agnostic and/or prognostic biomarker,we also reviewed the circulating TIMP-1 levels in translational and clinical studies.Sultan Almuntashiri Abdullah Alhumaid Yin Zhu Yohan Han Saugata Dutta Ohmed Khilji Duo Zhang Xiaoyun Wang 2023Chinese Medical Journal Pulmonary and Critical Care Medicine2023,1,2:0
