Since 2005, organ donation and transplantation in China has undergone thorough reform, which complies with legislation requirements and ethical principles established by the World Health Organization(WHO). Reform in China has demonstrated the unwavering confidence and utmost determination of the Chinese government and the Chinese transplantation community. The year 2015 marked a historic turning point when voluntary donations from Chinese citizens became the sole legitimate source for organ transplantation. Since 2015, China has gradually established and refined the “Chinese Mode” and “China System” for organ donation and transplantation, fulfilling its political pledge of reform, and has garnered international recognition, and fostered a social culture which promotes organ donation. This article reviewed the history of reform on organ donation and transplantation in China, presented a new pattern of establishment of organ donation system in the new era of the country, and the direction of advances in the future.展开更多

文摘Dongyuemiao Member shale in the Sichuan Basin,China,is characterized by organic-rich shale intervals with different types of interbeds and accumulation modes.The aim of this study is to elucidate the impact of paleoenvironmental indicators on interbed development.With this aim in mind,we established an interbed classification scheme and quantified the development of different types of interbeds and their frequencies.We categorized the shale interbeds into three types based on interbed type:silt interbeds(SIs),shell fragment interbeds(SFIs),and shell skeleton interbeds(SSIs).The SIs,SFIs,and SSIs are respectively the products of extrabasinal low-density turbidity currents,intrabasinal debris flow,and intrabasinal low-density turbidity currents.We propose that variations in paleoenvironmental conditions primarily influenced the types of interbeds that developed but had minimal impact on the frequency of their development.Models depicting the interbed development within the 1st Submember of Dongyuemiao Member indicate that during the early Dongyuemiao depositional period,under conditions of relatively aridity,weak weathering,high terrigenous input,and strong hydrodynamic activity,SSIs were well developed.In the middle depositional period,as the climate gradually transitioned to more humid conditions,and the weathering intensity and amount of terrestrial input increased,the development of SIs and SFIs significantly increased.During the late depositional period,with a continuous decrease in terrestrial inputs and sedimentation rates,the development of SIs decreased while that of SSIs increased.

文摘Pentatricopeptide repeat(PPR)proteins are a large group of eukaryote-specific RNA-binding proteins that play pivotal roles in plant organelle gene expression.Here,we report the function of PPR21 in mitochondrial intron splicing and its role in maize kernel development.PPR21 is a typical P-type PPR protein targeted to mitochondria.The ppr21 mutants are arrested in embryogenesis and endosperm development,leading to embryo lethality.Null mutations of PPR21 reduce the splicing efficiency of nad2 intron 1,2,and 4 and impair the assembly and activity of mitochondrial complex I.Previous studies show that the P-type PPR protein EMP12 is required for the splicing of identical introns.However,our protein interaction analyses reveal that PPR21 does not interact with EMP12.Instead,both PPR21 and EMP12 interact with the small MutS-related(SMR)domain-containing PPR protein 1(PPR-SMR1)and the short P-type PPR protein 2(SPR2).PPR-SMR1 interacts with SPR2,and both proteins are required for the splicing of many introns in mitochondria,including nad2 intron 1,2,and 4.These results suggest that a PPR21-(PPR-SMR1/SPR2)-EMP12 complex is involved in the splicing of nad2 introns in maize mitochondria.

文摘The reform stems from honesty and determination. Since 2005, organ donation and transplantation in China has undergone thorough reform, which complies with legislation requirements and ethical principles established by the World Health Organization(WHO). Reform in China has demonstrated the unwavering confidence and utmost determination of the Chinese government and the Chinese transplantation community. The year 2015 marked a historic turning point when voluntary donations from Chinese citizens became the sole legitimate source for organ transplantation. Since 2015, China has gradually established and refined the “Chinese Mode” and “China System” for organ donation and transplantation, fulfilling its political pledge of reform, and has garnered international recognition, and fostered a social culture which promotes organ donation. This article reviewed the history of reform on organ donation and transplantation in China, presented a new pattern of establishment of organ donation system in the new era of the country, and the direction of advances in the future.

文摘Ending extreme poverty and achieving sustainable development by 2030 poses a significant challenge for de veloping countries.In the past decade,China has pioneered the Targeted Poverty Alleviation(TPA)strategy and implemented a range of anti-poverty programs,aiming to reconcile poverty reduction with environmental restoration.However,the effectiveness of the TPA strategy in facilitating sustainable development in the poor areas of China(PAC)remains unclear.Drawing on a perspective of systems,this study compiles a panel dataset of 832 nationally designated poverty-stricken counties in China from 2013 to 2020 and employ the coupling coordination degree model to examine the coupling and coordination relationships among economic,social,and environmental systems in the PAC.We find that during the TPA period,the socioeconomic level developed rapidly,while the environmental quality was slightly improved in the PAC.The TPA strategy promotes the co ordinated development of social,economic,and ecological systems in the PAC,shifting the relationship between human and environment from imbalance to coordination.Our findings underscore the necessity for the Chinese government to persist in its environmental restoration efforts in the PAC to guarantee a sustained development progress.

文摘FOXL 2 and CYP 19 B are crucial transcription factors in vertebrates and invertebrates that play pivotal roles in sex differentiation and gonadal development.The potential roles of the foxl 2 and cyp 19 b genes in sex determination and gonadal development in Cyprinus carpio var.koi were explored using a non-invasive RNA interference(RNAi)method,histopathological observation and qPCR.Results demonstrate that foxl 2 exhibited a sexually dimorphic expression pattern in gonads,with a notable expression in ovaries;cyp 19 b was expressed in all peripheral tissues,with a particularly prominent expression in brain and gonads.The knockdown of foxl 2 by RNAi resulted in delay in the development of the female gonads.Conversely,no notable alterations were discerned in the gonads of C.carpio var.koi following the knockdown of cyp 19 b.The upregulation of sox 9 a,amh,and cyp 19 b following foxl 2 knockdown indicates that foxl 2 may play a pivotal role in gonadal development.Nevertheless,further investigation is required to ascertain the potential role of cyp 19 b.This study elucidated the role of foxl 2 and enhanced the understanding of the mechanisms of sex determination and gonadal development in C.carpio var.koi.

文摘Research on the distribution and development of black shales in the Lianggaoshan Formation has been deficient,which has hindered exploration for lacustrine shale oil in the Sichuan Basin.Our study characterized the well logging data,core samples,outcrops,and geochemistry of black shales in the Lianggaoshan Formation in the Sichuan Basin.Our analysis focused on the lake basin evolution and the migration characteristics,paleoenvironmental features,formation mechanisms,and developmental model of the black shales.The results indicated that black shales in the Lianggaoshan Formation exhibited significant lateral migration,with an overall thickening trend from east to west.Within the 1st Member of the formation,black shale occurred as a single thick layer in the eastern region that gradually thinned toward the central region.Multiple sets of shale developed within the 2nd and 3rd members,and these had lower thicknesses than the 1st Member and migrated toward central Sichuan.Paleoproductivity and terrigenous input were the main factors controlling the deposition of black shales.A semi-humid climate influenced the deposition of black shales,bringing abundant freshwater,terrigenous debris,and nutrients into the basin.Decomposition of organic matter consumed oxygen in sediment and bottom water,causing localized oxygen deficiency in the strata.

文摘New-type urbanization(NTU)is proposed by China to solve unsustainable issues and improve green development efficiency(GDE)during the process of rapid urbanization.However,the impact mechanism of NTU on GDE is unclear.Using panel data of 282 prefecture-level cities in China from 2010 to 2019,we measured NTU and GDE to describe their spatiotemporal pattern and relationship evolution.The fixed effects panel model and mediating effect panel model were further utilized to analyze the benchmark impact,mediating mechanism and spatiotem-poral heterogeneity of NTU on GDE.The results showed that NTU improved,with the highest levels observed in the eastern region,while GDE increased with fluctuations,performing better in both the eastern and western regions.With the proportion of double-high cities increasing from 13.83%to 43.62%,the NTU-GDE relationship was upgraded.Overall,every 1%improvement in NTU increased GDE by 0.3111%,and the enterprise effect,resident effect and government effect played a positive mediating role from high to low.During the later stage of NTU,its impact on GDE strengthened significantly,and the mediating role of governments was optimized.The eastern region was the only region with three positive mediating roles of governments,enterprises and residents.These findings will promote GDE through NTU in China and serve as a valuable reference for sustainable global urbanization.

文摘Mitochondria are semi-autonomous organelles present in eukaryotic cells,containing their own genome and transcriptional machinery.However,their functions are intricately linked to proteins encoded by the nuclear genome.Mitochondrial transcription termination factors(mTERFs)are nucleic acid-binding proteins involved in RNA splicing and transcription termination within plant mitochondria and chloroplasts.Despite their recognized importance,the specific roles of mTERF proteins in maize remain largely unexplored.Here,we clone and functionally characterize the maize mTERF18 gene.Our findings reveal that mTERF18 mutations lead to severely undifferentiated embryos,resulting in abortive phenotypes.Early kernel exhibits abnormal basal endosperm transfer layer and a significant reduction in both starch and protein accumulation in mterf18.We identify the mTERF18 gene through mapping-based cloning and validate this gene through allelic tests.mTERF18 is widely expressed across various maize tissues and encodes a highly conserved mitochondrial protein.Transcriptome data reveal that mTERF18 mutations disrupt transcriptional termination of the nad6 gene,leading to undetectable levels of Nad6 protein and reduced complex I assembly and activity.Furthermore,transmission electron microscopy observation of mterf18 endosperm uncover severe mitochondrial defects.Collectively,these findings highlight the critical role of mTERF18 in mitochondrial gene transcription termination and its pivotal impact on maize kernel development.
文摘Objectives:The climate crisis demands urgent action from all sectors of society,including young people in higher education.While previous research has explored individual and contextual predictors of pro-environmental behaviour(PEB),the contribution of Positive Youth Development(PYD)remains underexplored.This study investigates the relationship between PYD dimensions(Competence,Confidence,Connection,Character,and Caring)and two environmental outcomes:environmental habits and climate change awareness,considering gender differences.Methods:A cross-sectional study was conducted with a sample of 1779 students from 10 universities in Andalusia(Spain).Data were collected through an online survey assessing PYD indicators,PEB,and sociodemographic variables.Descriptive statistics,t-tests,correlation analyses,and multiple mediation models were performed.Results:Descriptive analyses indicated moderate levels of PYD dimensions and PEB across the sample.Among the 5 Cs,Caring had a positive association with environmental habits(r 0.22,p 0.001)and climate change awareness(r=<=0.30,p 0.001).Character also had a positive effect on both environmental habits(r 0.23,p 0.001)and climate<=<change awareness(r 0.30,p 0.001).Competence and Confidence were not significantly associated,and Connection=<demonstrated limited predictive value,potentially influenced by contextual or social factors.Gender differences were also identified,with women showing higher scores in Character(d 0.29,p 0.001),Caring(d 0.63,p 0.001),=<=<environmental habits(d 0.20,p 0.001)and climate change awareness(d 0.40,p 0.001),while men scored higher in=<=<Competence(d 0.57,p 0.001)and Confidence(d 0.22,p 0.001).Mediation analyses indicated that the association=<=<between gender and environmental habits was totally explained by Character(β95%CI:and=-0.02;-0.04;-0.01)Caring(β95%CI:Furthermore,the relationship between gender and climate change awareness=-0.04;-0.05,-0.02).was partially mediated by Character(β95%CI:and Caring(β95%CI:=-0.03;-0.05;-0.02)=-0.05;-0.07,-0.03).Conclusions:Females showed more environmental habits and climate change awareness than males,because of their greater scores in both Caring and Character dimensions of PYD.These findings highlight the importance of the PYD for promoting PEB and engaged citizens among young adults.Gender-sensitive and interdisciplinary interventions,such as environmental volunteering and community-based programmes,are recommended for university contexts to enhance sustainable development behaviours and values.

文摘The Goral municipality of Ždiar(a Conservation Reserve of Folk Architecture since 1977)is one of the most attractive areas in Slovakia under the growing influence of the developing tourism.Since 1949 it has been part of the protection zone of the Tatra National Park and since 1993 it has been part of the transition zone of the Tatra Biosphere Reserve.In recent years,tourism has taken a major role in the transition zone of this biosphere reserve.In the presented contribution,we therefore evaluate the impact of developing tourism in the cadastral area of the municipality ofŽdiar between 1950 and 2022.We rely primarily on available statistical data from various sources and on the analysis of the historical and contemporary landscape structure.During this period,almost 50%of the area has changed land cover.The activities that have significantly changed the landscape include afforestation,deforestation,agrointensification,deurbanisation(naturalisation),urbanisation(anthropisation):tourism development and construction of a water reservoir.Tourism has become the main driver of the economy here and opens up opportunities especially for local inhabitants.However,the lack of completed tourism infrastructure is a drawback.We recommend the establishment of the Coordinating Council of the Tatra Biosphere Reserve and permanent employees at the National Park Administration.
