Mangrove and salt marsh ecosystems are one of the most productive ecosystems in terrestrial ecosystems, playing an important role in global carbon (C) cycling. The anaerobic condition in coastal wetland usually impedes the decomposition of soil organic carbon (SOC). However, the intrinsic stabilization mechanisms of SOC other than environmental factors are poorly understood in coastal wetland. In this paper, we investigated the relative contribution of mineral association and chemical compounds in maintaining the stabilization of SOC in the mangrove/salt marsh ecotone, and how the microbial community is involved in the stabilization. From NMR spectroscopy, we found that the SOC molecular structure of Spartina. alterniflora soils is simpler than that in mangrove forest, indicating an increased SOC decomposition with invasion of S. alterniflora. On the contrary, the molecular structure of SOC in mangrove forest was dominated by recalcitrant aromatic C. Meanwhile, the larger fractions of silt/clay content in S. alterniflora and the transitional community were corresponding to higher percentage of mineral organic carbon (MOC), which suggest that the SOC in S. alterniflora vegetated soil was mainly protected by the mineral association. The transitional community contained highest MOC content probably due to both physical protection of mineral association and recalcitrant C input from adjacent mangroves. We also found that the fraction of SOC and its chemical structure of functional groups were associated with microbial communities. This study revealed the occurrence of different SOC stabilization mechanisms between mangroves and salt marshes. The knowledge gained may help to make predictions about future SOC dynamics as the different stabilization processes may response to climate change or human activities differently.

Labile fractions of soil carbon pools are sensitive to environmental changes, which would influence the stabilization of soil carbon. However, it is unclear whether the dynamics of labile organic carbon (LOC) and soil organic carbon (SOC) are coupled and how they influence each other in coastal wetland. The present work investigated the trends of soil carbon fractions among mangrove and Spartina alterniflora communities with different stand ages (1, 5, 10, and 15 years), at Quanzhou Bay Estuary Wetland Nature Reserve, China. We found that SOC in a mangrove ecosystem increased over time, while there was no significant trend in S. alterniflora dominated ecosystems. The highest LOC of mangrove appeared in 5-year-old communities, and then decreased with stand age. In S. alterniflora communities, content of labile fractions increased with the stand age. These trends indicated different soil carbon dynamics when comparing mangrove and S. alterniflora ecosystems. The development of mangroves promoted accumulation of recalcitrant carbon, while S. alterniflora ecosystems contributed to an increase of labile carbon. This phenomenon is probably caused by the characteristics of vegetation and the hydrological conditions. Mangroves contribute more refractory organic carbon to the soil carbon pool, while accumulation of LOC in S. alterniflora communities may inhibit the stabilization of SOC. Our study on the relationship of LOC and SOC implies that complex interactions occur among soil carbon pools and environmental conditions in coastal wetlands, suggesting soil carbon models should take into account decoupled dynamics of LOC and SOC.

Energy expenditure in buildings and transportation is about 63% of all global energy consumption, making them major targeted sectors for energy conservation and carbon dioxide (CO2) emission reduction. To save energy in cooling of automobiles and buildings, transparent passive-cooling films with 90-nm-diameter zinc oxide (ZnO) particles dispersed in low density polyethylene were manufactured. These films filter out the high-energy region of visible light (Vis), block ultraviolet (UV) light, and allow infrared light to pass through by utilizing light scattering due to nanoparticles (NPs) and refraction from lamellar crystals in the film. Transmissivities of the films decrease as NP concentration, film thickness, and crystallinity increase. Passive-cooling performance tests show that the films have a temperature reduction (ΔT) of up to 14.95 °C around midday, which is substantially better than that reported for similar films. The volume involved in the passive-cooling test is found to be critically important. ΔT initially declines exponentially and then levels-off as the enclosed volume to window area ratio, or specific volume (SV), increases. An empirical model is proposed for the relationship between ΔT and SV for more appropriate measurements of passive-cooling performance. SVs of passenger cars and office buildings are located within the most sensitive range of the ΔT-SV curve of the fabricated films.

Low-velocity drop weight impact experiments of plain-woven Twaron® CT 612 at an impact energy of 15, 20, 30 J are carried out on a 9250HV drop weight impact tester. Specially treated specimens are designed and used to deal with boundary conditions because the fabric is too flexible and cannot be fixed precisely. Experimental results reaffirm that TwaronⓇ is an impact-rate-sensitive material and that a greater initial impact energy resulted in a larger breaking load, greater failure strain, larger energy absorption and shorter contact duration to the fabric in the impact process., The commercial code ANSYSⓇ-AUTODYN is employed for impact FE analysis on a physically based impact model which is designed basing on the fabric's geometry parameters and the experimental set-up. The dynamic mechanical parameters of TwaronⓇ is analyzed and applied to FE model to describe the rate-sensitive mechanical properties through a three-element spring-dashpot model. Standard earth gravity is applied to the impact model to reflect the impact process realistically as well. The results indicate that a remarkably close agreement is obtained between the simulation and experimental results in various impact scenarios. Thus, the energy absorption mechanisms and stress distributions during the impact process are clarified. The influence of specimen shape and size are also analyzed systemically. These results indicate that the present experimental set-up and the developed fabric geometry model are effective at investigating many additional mechanical problems in textile fabrics and/or flexible material structures.

Placenta specific protein 1 (PLAC1) is thought to be important for murine and human placentation because of its abundant expression in placenta; however, the trophoblast subtypes that express PLAC1 at the fetomaternal interface and the major role of PLAC1 in placentation are still unclear. This study investigated the expression pattern of PLAC1 at the human fetomaternal interface and its involvement in trophoblast syncytialization. Localization of PLAC1 at the fetomaternal interface was studied using in situ hybridization (ISH) and immunohistochemistry (IHC) assays. Real time RT-PCR and Western Blot were employed to exhibit the expression pattern of PLAC1 during human spontaneous syncytialization of term primary cytotrophoblast cells (CTBs). Spontaneous syncytialization of a primary term CTBs model transfected with siRNA specific to PLAC1 was used to investigate the role of PLAC1 during human trophoblast syncytialization. The results showed that PLAC1 was mainly expressed in the human villous syncytiotrophoblast (STB) layer throughout gestation, and the expression level of PLAC1 was significantly elevated during human trophoblast syncytialization. Down-regulation of PLAC1 via specific PLAC1 siRNA transfection attenuated spontaneous syncytialization of primary term CTBs (p

Despite an increase of refugee children in Korea, there is a dearth of empirical study on their school adjustment. The purpose of this study is to examine group differences in the level of school adjustment by sex, school level, Korean language proficiency, having a nationality, refugee status, and discrimination experience, and to test a mediating role of perceived social support between depression and school adjustment. We recruited 65 refugee children via purposive and snowball sampling methods, and conducted face-to-face survey for younger children and a self-administered survey for older children from July to October 2017. We found group differences in school adjustment according to having a nationality, refugee status, and discrimination experience. We also found a full mediating effect of social support in the relationship between depression and school adjustment. Based on the results, we discussed ways in which the Korean school system and social-work service agencies need to help refugee children increase their adaptability in schools.

Retroviral and lentiviral vector pseudotypes (based on human immunodeficiency virus type 1, HIV-1) have been used for stable and safe gene transfer because of their broad host ranges and high mechanical strength. In the present study, a recombinant avian leukosis virus subgroup J (ALV-J) polypeptide pseudotyped with lentivirus membrane glycoproteins gp85 and gp37, HIV/env-ALV, was generated, characterized in vitro and evaluated for its ability to infect natural host cells. We optimized the newly developed micro-neutralization (MN) assay using recombinant pseudovirion HIV/env-ALV expressing enhanced green fluorescent protein and well-characterized sera from chickens with confirmed ALV-J disease or virus-free controls. HIV/env-ALV could infect CEF and DF-1 but not pk15, 293FT, MDCK or VERO E6 cells, therefore demonstrating a cellular tropism similar to the wild-type ALV-J. The MN assay indicated that the IC50 values of positive sera offered a considerable advantage in both speed and accuracy. These results suggest that this pseudotyped lentivirus is a good model for studying the functions of ALV-J env and that the MN assay is a reliable serological method for assessing antibody levels in investigating the actual status of the current ALV-J epidemic. These recombinant pseudovirions may prove to be useful for studying ALV-J biology in lower biosafety level laboratory environments, and also for the detection and quantification of neutralizing antibodies to ALV-J in a manner akin to ELISA assays, but that would also be applicable to other viruses.

Circulating monocytes have been exploited as an important progenitor cell resource for hepatocytes in vitro and are instrumental in the removal of fibrosis. We investigated the significance of monocytes in peripheral blood stem cells (PBSC) for the treatment of liver cirrhosis.Rat CD14+ monocytes in PBSC were mobilized with granulocyte-colony-stimulating factor (G-CSF) and harvested by magnetic cell sorting (MACS). Female rats with carbon tetrachloride (CCl₄-induced liver cirrhosis were injected CM-DiI-labeled monocytes, CD14⁻ cells (1 x 10⁷ cells/rat) or saline via the portal vein.Rat CD14+ and CD11b+ monocytes in PBSC were partly positive for CD34, CD45, CD44, Oct3/4 and Sox2, suggesting monocytes with progenitor capacity. Compared with CD14⁻ cell-infused and saline-injected rats, rats undergoing monocyte transplantation showed a gradually increased serum albumin level and decreased portal vein pressure, resulting in a significantly improved survival rate. Meanwhile, monocyte transplantation apparently attenuated liver fibrosis by analysis for fibronectin, α2-(1)-procollagen, α-smooth muscle aorta (SMA) and transforming growth factor (TGF)-β. Transplanted monocytes mainly clustered in periportal areas of liver, in which 1.8% cells expressed hepatocyte marker albumin and CK18. The expression level of hepatocyte growth factor (HGF), TGF-α, extracellular matrix (EGF) and vascular endothelial growth factor (VEGF) increased, while monocyte transplantation enhanced hepatocyte proliferation. On the other hand, the activities and expression of matrix metalloproteinases (MMP) increased while tissue inhibitor of metalloproteinase (TIMP)-1 expression significantly reduced in monocyte-transplanted livers. Some transplanted monocytes expressed MMP-9 and -13.The data suggest that CD14+ monocytes in PBSC contribute to hepatocyte regeneration and extracellular matrix (ECM) remodeling in rat liver cirrhosis much more than CD14⁻ cells, and might offer a therapeutic alternative for patients with liver cirrhosis.
