To determine the precise relationship between the GBR layers and the first appearance datum （FAD） of the conodont Chiosella timorensis, four Lower-Middle Triassic sections from the Nanpanjiang Basin, including the Gaimao, Bianyang lI, Zuodeng and Wantou sections have been studied in detail. Detailed conodont biostratigraphy convinces us that there is no exact temporal relationship between the GBR layers and first occurrence of Ch. timorensis. Moreover, the numbers of the GBR layers are different from the place to place within the Nanpanjiang Basin, and the time span of the GBR layers was much longer than previously estimated. Global correlations show that the FAD of Ch. timorensis is contemporaneous basinwide and worldwide and more suitable marker defining the Olenekian-Anisian boundary （Early-Middle Triassic boundary） than any other proxies.展开更多

Methods： Human chondrocytes were isolated and cultured on bone matrix gelatin to form an artificial cartilage model in vitro with or without MON toxin. Cell viability was determined by 3-（4,5-dimethylthiazol-2-yl）-2,5-diphenyltetrazolium bromide （MTT） assay. The expression of aggrecan and type II collagen in the cartilage was determined using immunocytochemical staining. Results： MON toxin inhibited chondrocyte viability in dose-dependent and time-dependent manners. MON reduced aggrecan and type Ⅱ collagen syntheses in the tissue-engineered cartilage. MON also increased the expression of matrix metalloproteinase-1 （MMP-1）, MMP-13, BC4 epitopes, and CD44 in cartilages. However, the expression of 3B3（-） epitopes in cartilages was inhibited by MON. Selenium partially alleviated the damage of aggrecan induced by MON toxin. Conclusion： MON toxin promoted the catabolism of aggrecan and type II collagen in human chondrocytes.展开更多

文摘In this paper,we present the second post-Newtonian solution for the quasi-Keplerian motion of a test particle in the regular Simpson–Visser black-bounce spacetime which has a bounce parameter a.The obtained solution is formulated in terms of orbital energy,angular momentum,and the bounce parameter of the black hole.We explicitly analyze the leading effects of the bounce parameter which has dimensions of length,on the test particle’s orbit,including the periastron advance and orbital period.Then,we apply this model to the precessing motion of OJ 287 and determine the upper limits of the dimensionless bounce parameter as a/m=3.45±0.01,where m is the mass of the regular black hole.Compared with the bound given by the periastron advance of star S2,our bound on a/m is reduced by one order of magnitude,although our upper limit of a still needs further improvement.

文摘Rhodioloside has been shown to protect cells from hypoxia injury,and bone marrow mesenchymal stem cells have a good effect on tissue repair.To study the effects of rhodioloside and bone marrow mesenchymal stem cells on spinal cord injury,a rat model of spinal cord injury was established using the Infinite Horizons method.After establishing the model,the rats were randomly divided into five groups.Rats in the control group were intragastrically injected with phosphate buffered saline(PBS)(5μL).PBS was injected at 6 equidistant points around 5 mm from the injury site and at a depth of 5 mm.Rats in the rhodioloside group were intragastrically injected with rhodioloside(5 g/kg)and intramuscularly injected with PBS.Rats in the mesenchymal stem cell(MSC)group were intramuscularly injected with PBS and intramuscularly with MSCs(8×10^6/mL in a 50-μL cell suspension).Rats in the Ad-HIF-MSC group were intragastrically injected with PBS and intramuscularly injected with HIF-1 adenovirus-infected MSCs.Rats in the rhodioloside+Ad-HIF-MSC group were intramuscularly injected with MSCs infected with the HIF-1 adenovirus and intragastrically injected with rhodioloside.One week after treatment,exercise recovery was evaluated with a modified combined behavioral score scale.Hematoxylin-eosin staining and Pischingert’s methylene blue staining were used to detect any histological or pathological changes in spinal cord tissue.Levels of adenovirus IX and Sry mRNA were detected by real-time quantitative polymerase chain reaction and used to determine the number of adenovirus and mesenchymal stem cells that were transfected into the spinal cord.Immunohistochemical staining was applied to detect HIF-1 protein levels in the spinal cord.The results showed that:(1)compared with the other groups,the rhodioloside+Ad-HIF-MSC group exhibited the highest combined behavioral score(P<0.05),the most recovered tissue,and the greatest number of neurons,as indicated by Pischingert’s methylene blue staining.(2)Compared with the PBS group,HIF-1 protein expression was greater in the rhodioloside group(P<0.05).(3)Compared with the Ad-HIF-MSC group,Sry mRNA levels were higher in the rhodioloside+Ad-HIF-MSC group(P<0.05).These results confirm that rhodioloside combined with bone marrow mesenchymal stem cells can promote the recovery of spinal cord injury and activate the HIF-1 pathway to promote the survival of bone marrow mesenchymal stem cells and repair damaged neurons within spinal cord tissue.This experiment was approved by the Animal Ethics Committee of Gansu University of Traditional Chinese Medicine,China(approval No.2015KYLL029)in June 2015.

文摘The Triassic ＂Green-bean Rock＂ （GBR） layers were widely recognized around the Early-Middle Triassic boundary interval in the Nanpanjiang Basin, South China. To determine the precise relationship between the GBR layers and the first appearance datum （FAD） of the conodont Chiosella timorensis, four Lower-Middle Triassic sections from the Nanpanjiang Basin, including the Gaimao, Bianyang lI, Zuodeng and Wantou sections have been studied in detail. Detailed conodont biostratigraphy convinces us that there is no exact temporal relationship between the GBR layers and first occurrence of Ch. timorensis. Moreover, the numbers of the GBR layers are different from the place to place within the Nanpanjiang Basin, and the time span of the GBR layers was much longer than previously estimated. Global correlations show that the FAD of Ch. timorensis is contemporaneous basinwide and worldwide and more suitable marker defining the Olenekian-Anisian boundary （Early-Middle Triassic boundary） than any other proxies.

文摘Aero-optical effects for starlight transmission in the high-speed flow field will reduce the accuracy of the star sensor on an aircraft.Numerical simulations for aero-optical effects usually require plenty of calculations,which cause difficulties when designing a celestial navigation system for a high-speed aircraft.In this study,an Aero-Optical Simulator For Starlight Transmission(AOSST)in the boundary layer is developed.It effectively reduces the computational burden compared to that of the widely used CFD simulation,and it achieves satisfactory accuracy.In this simulator,gas ellipsoids satisfying certain design rules are used to simulate coherent density structures in boundary layers.Design rules for the gas ellipsoids are found from published experimental and high-fidelity CFD simulation results.The generated wavefront distortion by AOSST is anchored with the scale law for aero-optical distortion in the boundary layer by determining some control parameters,which enables the simulator to output reliable results over a wide range of flight states.Four numerical examples are provided to verify the performance of AOSST.The results demonstrate that AOSST is able to simulate the directional dependence of aero-optical distortions in boundary layers,the variation trend of distorted wavefront shapes with Reynolds number,and the grayscale distribution on the disturbed star map.

文摘Objective： To investigate the effects of mycotoxin moniliformin （MON） on the metabolism of aggrecan and type 11 collagen in human chondrocytes in vitro and the relationship between MON and Kashin-Beck disease （KBD）. Methods： Human chondrocytes were isolated and cultured on bone matrix gelatin to form an artificial cartilage model in vitro with or without MON toxin. Cell viability was determined by 3-（4,5-dimethylthiazol-2-yl）-2,5-diphenyltetrazolium bromide （MTT） assay. The expression of aggrecan and type II collagen in the cartilage was determined using immunocytochemical staining. Results： MON toxin inhibited chondrocyte viability in dose-dependent and time-dependent manners. MON reduced aggrecan and type Ⅱ collagen syntheses in the tissue-engineered cartilage. MON also increased the expression of matrix metalloproteinase-1 （MMP-1）, MMP-13, BC4 epitopes, and CD44 in cartilages. However, the expression of 3B3（-） epitopes in cartilages was inhibited by MON. Selenium partially alleviated the damage of aggrecan induced by MON toxin. Conclusion： MON toxin promoted the catabolism of aggrecan and type II collagen in human chondrocytes.

文摘Hexagonal MnMX-based(M=Co or Ni,X=Si or Ge)alloys exhibit giant reversible barocaloric effects.However,giant volume expansion would result in the as-cast MnMX ingots fragmenting into powders,and inevitably bring the deterioration of mechanical properties and formability.Grain fragmentation can bring degradation of structural transformation entropy change during cyclic application and removal of pressure.In this paper,giant reversible barocaloric effects with high thermal cycle stability can be achieved in the epoxy bonded(MnCoGe)0.96(CuCoSn)0.04 composite.Giant reversible isothermal entropy change of 43.0 J·kg^(−1)·K^(−1) and adiabatic temperature change from barocaloric effects(ΔT_(BCE))of 15.6 K can be obtained within a wide temperature span of 30 K at 360 MPa,which is mainly attributed to the integration of the change in the transition temperature driven by pressure of−101 K·GPa^(−1) and suitable thermal hysteresis of 11.1 K.Further,the variation of reversibleΔ_(TBCE) against the applied hydrostatic pressure reaches up to 43 K·GPa^(−1),which is at the highest level among the other reported giant barocaloric compounds.More importantly,after 60 thermal cycles,the composite does not break and the calorimetric curves coincide well,demonstrating good thermal cycle stability.

文摘The flow-through electro-Fenton(EF-T)reactor with WBC cathode was designed to remove florfenicol(FF).The activated WBC cathode was prepared by facile carbonization and activation methods,and featured high specific surface area,natural multi-channel structure,abundant oxygen-containing groups,good hydrophilicity,and excellent O_(2)reducing capacity.WBC cathode was located above Ti/Ru-IrO_(2)mesh anode.O_(2)evolved at the anode was carried to the inner wall of channel of WBC by the force of buoyancy and water flow,which increases oxygen source of H_(2)O_(2)generation at the cathode.The flow-through system by using WBC electrode promote the mass transfer of O_(2)and FF.The production amount of H_(2)O_(2)at activated WBC was 32.2 mg/L,which was almost twice as much as that at non-activated WBC(15.0 mg/L).FF removal ratio in EF-T system was 98%,which was much higher than that of traditional flow-by electro-Fenton(EF-B,33%)or single electrooxidation system(EO,16%).EF-T system has the lowest energy consumption(4.367 kWh/kg)among the three electrochemical systems.The cathodic adsorption,anodic electrooxidation,and EF reaction are responsible for the degradation of FF.After five consecutive cycle experiments,FF removal ratio was still 98%,indicating WBC has the good stability.

文摘Objective This study aimed to explore the relationships between residential greenness and cardiometabolic risk factors among rural adults in Xinjiang Uygur Autonomous Region(Xinjiang)and thus provide a theoretical basis and data support for improving the health of residents in this region.Methods We recruited 9,723 adult rural residents from the 51st Regiment of the Third Division of the Xinjiang Production and Construction Corps in September 2016.The normalized difference vegetation index(NDVI)was used to estimate residential greenness.The generalized linear mixed model(GLMM)was used to examine the association between residential greenness and cardiometabolic risk factors.Results Higher residential greenness was associated with lower cardiometabolic risk factor prevalence.After adjustments were made for age,sex,education,and marital status,for each interquartile range(IQR)increase of NDVI500-m,the risk of hypertension was reduced by 10.3%(OR=0.897,95%CI=0.836-0.962),the risk of obesity by 20.5%(OR=0.795,95%CI=0.695-0.910),the risk of type 2 diabetes by 15.1%(OR=0.849,95%CI=0.740-0.974),and the risk of dyslipidemia by 10.5%(OR=0.895,95%CI=0.825-0.971).Risk factor aggregation was reduced by 20.4%(OR=0.796,95%CI=0.716-0.885)for the same.Stratified analysis showed that NDVI500-m was associated more strongly with hypertension,dyslipidemia,and risk factor aggregation among male participants.The association of NDVI500-m with type 2 diabetes was stronger among participants with a higher education level.PM10 and physical activity mediated 1.9%-9.2%of the associations between NDVI500-m and obesity,dyslipidemia,and risk factor aggregation.Conclusion Higher residential greenness has a protective effect against cardiometabolic risk factors among rural residents in Xinjiang.Increasing the area of green space around residences is an effective measure to reduce the burden of cardiometabolic-related diseases among rural residents in Xinjiang.
