Plants sequester carbon through photosynthesis and provide primary productivity for the ecosystem. However, they also simultaneously consume water through transpiration, leading to a carbon-water balance relationship. Agricultural production can be regarded as a form of carbon sequestration behavior.From the perspective of the natural-social-economic complex ecosystem, excessive water usage in food production will aggravate regional water pressure for both domestic and industrial purposes. Hence, achieving a harmonious equilibrium between carbon and water resources during the food production process is a key scientific challenge for ensuring food security and sustainability. Digital intelligence(DI) and cyber-physical-social systems(CPSS) are emerging as the new research paradigms that are causing a substantial shift in the conventional thinking and methodologies across various scientific fields, including ecological science and sustainability studies. This paper outlines our recent efforts in using advanced technologies such as big data, artificial intelligence(AI), digital twins, metaverses, and parallel intelligence to model, analyze, and manage the intricate dynamics and equilibrium among plants, carbon, and water in arid and semiarid ecosystems. It introduces the concept of the carbon-water balance and explores its management at three levels: the individual plant level, the community level, and the natural-social-economic complex ecosystem level. Additionally, we elucidate the significance of agricultural foundation models as fundamental technologies within this context. A case analysis of water usage shows that, given the limited availability of water resources in the context of the carbon-water balance, regional collaboration and optimized allocation have the potential to enhance the utilization efficiency of water resources in the river basin. A suggested approach is to consider the river basin as a unified entity and coordinate the relationship between the upstream, midstream and downstream areas. Furthermore, establishing mechanisms for water resource transfer and trade among different industries can be instrumental in maximizing the benefits derived from water resources.Finally, we envisage a future of agriculture characterized by the integration of digital, robotic and biological farming techniques.This vision aims to incorporate small tasks, big models, and deep intelligence into the regular ecological practices of intelligent agriculture. 展开更多

Individual characteristics, family characteristics, and sociological factors were considered as independent variables, and long-term care model was the dependent variable in the three binary logistic regression method. <strong>Results:</strong> Age, gender, marriage, and disability were the most important factors influencing the choice of long-term care mode, including the willingness of the differently abled elderly. Family care can no longer meet the needs of the severely disabled elderly. Long-term care for such elderly people should be undertaken by professional and specialized social institutions. <strong>Conclusion: </strong>Multi-level services should be provided according to the elderly peoples’ needs, and the skill and expertise of professional personnel of care institutions should be strengthened. The government should deploy fund-raising initiatives, actively use the power of non-governmental organizations, and strive to resolve the financial issues faced by the empty-nested elderly people with disability. 展开更多

Ginkgol C17:1 has been shown to inhibit apoptosis and migration of cancer cells,but the underlying mechanisms are not fully elucidated.In this study,we explored whether the inhibitory effects of Ginkgol C17:1 were associated with epidermal growth factor receptor(EGFR) and PI3K/Akt signaling.The results showed that EGF treatment increased the phosphorylation of EGFR,PI3 K,Akt,mTOR and NF-κB,and also enhanced the proliferation,migration and invasion of HepG2 cells.Ginkgol C17:1 dose-dependently inhibited EGF-induced phosphorylation/activation of all the key components including EGFR,PI3 K,Akt,mTOR and NF-kB,leading to a significant reduction either of proliferation or migration and invasion of HepG2 cells.Notably,treatment with Ginkgol C17:1 in mice suppressed the growth of tumor mass in vivo,and expression of EGFR in the tumor tissue.The results suggest that Ginkgol C17:1 is a potent tumor inhibiting compound that acts on EGF-induced signal transduction of the PI3K/Akt signaling pathways,and may represent a clinically interesting candidate for cancer therapy. 展开更多

The origin of T cells in the teleost's brain is unclear.While viewing the central nervous system(CNS)as immune privileged has been widely accepted,previous studies suggest that T cells residing in the thymus but not in the spleen of the teleost play an essential role in communicating with the peripheral organs.Here,we identified nine T cell subpopulations in the thymus and spleen of orange-spotted grouper(Epinephelus coioices)through single-cell RNA-sequencing analysis.After viral CNS infection with red-spotted grouper nervous necrosis virus(RGNNV),the number of slc43a2^(+)T cells synchronously increased in the spleen and brain.During the infection tests in asplenic zebrafish(tlx1^▲zebrafish model),no increase in the number of slc43a2^(+)T cells was observed in the brain.Single-cell transcriptomic analysis indicated that slc43a2^(+)T cells mature and functionally differentiate within the spleen and then migrate into the brain to trigger an immune response.This study suggests a novel route for T cell migration from the spleen to the brain during viral infection in fish. 展开更多

The concentration of PM_(2.5)has considerably reduced in recent years,but remains relatively high in China.In particular,the increasing contribution of organic compounds to PM_(2.5)generates popular pressure for further reductions,resulting in an urgent need to study organic aerosol(OA).To investigate the molecular composition and source contribution of OA in the rural area of the Guanzhong Plain,Northwest China,PM_(2.5)samples were collected during 3–23 August 2016 and 5–20 January 2017 and studied for more than 100 organic tracer compounds.The mean concentration of total measured organic compounds is 662±296 ng/m^(3)in summer and 3258±1925 ng/m^(3)in winter.Levoglucosan is the most abundant single compound found throughout the sampling period,which is a crucial tracer for biomass burning emissions,preliminary suggesting that biomass burning is an essential source of OA.In summer,organic compounds such as lipid compounds,sugar compounds,and polycyclic aromatic hydrocarbons(PAHs),more come from higher plants,wood burning,vehicle exhausts,plastic waste,and other direct emission sources.Oxygenated PAHs(OPAHs),nitrophenols,and phthalic acids more come from the atmosphere through the oxidation reaction of aromatic precursors,especially photochemical oxidation.However,in winter,most of the increases in concentrations of organic compounds are attributed to biomass burning.The analysis of a haze event(14–19 January 2017)during the winter sampling period shows that the increases in the concentration of organic compounds are unaccompanied by strong secondary formation under lower relative humidity(49.1%±13.5%).The main reason for the growth of OA in this haze event is the accumulation of primary OA(POA).The source apportionment by the positive matrix factorization(PMF)model shows that biomass burning(37.1%)is the primary source of OA in the rural regions of the Guanzhong Plain,especially in winter(40.6%).The contribution of secondary formation decreases from 26.0%in summer to 16.9%in winter,and the contribution of fossil fuel emissions is comparable across both seasons. 展开更多

While somatosensory over-reactivity is a common feature of autism spectrum disorders such as fragile X syndrome(FXS),the thalamic mechanisms underlying this remain unclear.Here,we found that the developmental elimination of synapses formed between the principal nucleus of V(PrV)and the ventral posterior medial nucleus(VPm)of the somatosensory system was delayed in fragile X mental retardation 1 gene knockout(Fmr1 KO)mice,while the developmental strengthening of these synapses was disrupted.Immunohistochemistry showed excessive VGluT2 puncta in mutants at P12–13,but not at P7–8 or P15–16,confirming a delay in somatic pruning of PrV-VPm synapses.Impaired synaptic function was associated with a reduction in the frequency of quantal AMPA events,as well as developmental deficits in presynaptic vesicle size and density.Our results uncovered the developmental impairment of thalamic relay synapses in Fmr1 KO mice and suggest that a thalamic contribution to the somatosensory over-reactivity in FXS should be considered. 展开更多

Differences in progress across sustainable development goals(SDGs)are widespread globally;meanwhile,the rising call for prioritizing specific SDGs may exacerbate such gaps.Nevertheless,how these progress differences would influence global sustainable development has been long neglected.Here,we present the first quantitative assessment of SDGs’progress differences globally by adopting the SDGs progress evenness index.Our results highlight that the uneven progress across SDGs has been a hindrance to sustainable development because(1)it is strongly associated with many public health risks(e.g.,air pollution),social inequalities(e.g.,gender inequality,modern slavery,wealth gap),and a reduction in life expectancy;(2)it is also associated with deforestation and habitat loss in terrestrial and marine ecosystems,increasing the challenges related to biodiversity conservation;(3)most countries with low average SDGs performance show lower progress evenness,which further hinders their fulfillment of SDGs;and(4)many countries with high average SDGs performance also showcase stagnation or even retrogression in progress evenness,which is partly ascribed to the antagonism between climate actions and other goals.These findings highlight that while setting SDGs priorities may be more realistic under the constraints of multiple global stressors,caution must be exercised to avoid new problems from intensifying uneven progress across goals.Moreover,our study reveals that the urgent needs regarding SDGs of different regions seem complementary,emphasizing that regional collaborations(e.g.,demand-oriented carbon trading between SDGs poorly performed and well-performed countries)may promote sustainable development achievements at the global scale. 展开更多

Background and Aims:Decompensated cirrhotic patients with hepatitis C(HCV)are often under-represented in clinical trials.We aimed to evaluate pooled data on the efficacy and safety of sofosbuvir(SOF)-based regimens in these patients.Methods:We conducted a systemic review and meta-analysis by searching multiple databases for studies published from October 2010 to October 2020.Outcomes of interest were sustained virologic response(SVR)and safety of SOFbased regimens in decompensated HCV patients.Two reviewers independently performed the study selection and data extraction.Results:We included 33 studies that enrolled 5,302 HCV patients.The pooled SVR rate in decompensated patients with SOF-based regimens was 85.1%(95%CI:82.8–87.3).Patients on SOF/velpatasvir±ribavirin achieved a significantly higher SVR(91.0%,95%CI:87.7–93.9)than that of SOF/ledipasvir±ribavirin[(86.3%,95%CI:84.6–87.8);p=0.004],or on SOF/daclatasvir±ribavirin(82.4%,95%CI:78.2–86.2%;p<0.001).Adding ribavirin to SOFbased regimens(pooled SVR 84.9%,95%CI:81.7–87.9)did not significantly increase the SVR[83.8%(95%CI:76.8–89.8%;p=0.76)]in decompensated patients,which was also true in subgroup analyses for each regimen within the same treatment duration.However,adding ribavirin significantly increased the frequency of adverse events from 52.9%(95%CI:28.0–77.1)to 89.2%(95%CI:68.1–99.9)and frequency of severe events.The pooled incidence of hepatocellular carcinoma and case-fatality of decompensated patients were 3.1%(95%CI:1.5–5.0)and 4.6%(95%CI:3.1–6.3),respectively.The overall heterogeneity was high.There was no publication bias.Conclusions:The analysis found that 12 weeks of SOF/velpatasvir without ribavirin is the preferred therapy,with a significantly higher SVR compared with other SOF-based regimens in decompensated HCV patients. 展开更多

Background:Nuclear Yes1-associated transcriptional regulator(YAP1)promotes tumor progression.However,the function of cytoplasmic YAP1 in breast cancer cells and its impact on the survival of breast cancer patients remain unclear.Our research aimed to explore the biological function of cytoplasmic YAP1 in breast cancer cells and the possibility of cytoplasmic YAP1 as a predictive marker of breast cancer survival.Methods:We constructed cell mutant models,including NLS-YAP15SA(nuclear localized),YAP1S94A(incapable of binding to the TEA domain transcription factor family)and YAP1S127D(cytoplasmic localized),and used Cell Counting Kit-8(CCK-8)assays,5-ethynyl-2’-deoxyuridine(EdU)incorporation assays,and Western blotting(WB)analysis to detect cell proliferation and apoptosis.The specific mechanism of cytoplasmic YAP1-mediated endosomal sorting complexes required for transport III(ESCRT-III)assembly was studied by co-immunoprecipitation,immunofluorescence staining,and WB analysis.Epigallocatechin gallate(EGCG)was used to simulate YAP1 retention in the cytoplasm in in vitro and in vivo experiments to study the function of cytoplasmic YAP1.YAP1 binding to NEDD4-like E3 ubiquitin protein ligase(NEDD4L)was identified using mass spectrometry and was verified in vitro.Breast tissue microarrays were used to analyze the relationship between cytoplasmic YAP1 expression and the survival of breast cancer patients.Results:YAP1 was mainly expressed in the cytoplasm in breast cancer cells.Cytoplasmic YAP1 promoted autophagic death of breast cancer cells.Cytoplasmic YAP1 bound to the ESCRT-III complex subunits charged multivesicular body protein 2B(CHMP2B)and vacuolar protein sorting 4 homolog B(VPS4B),promoting assembly of CHMP2B-VPS4B and activating autophagosome formation.EGCG retained YAP1 in the cytoplasm,promoting the assembly of CHMP2B-VPS4B to promote autophagic death of breast cancer cells.YAP1 bound to NEDD4L,and NEDD4L mediated ubiquitination and degradation of YAP1.Breast tissue microarrays revealed that high levels of cytoplasmic YAP1 were beneficial to the survival of breast cancer patients.Conclusions:Cytoplasmic YAP1 mediated autophagic death of breast cancer cells by promoting assembly of the ESCRT-III complex;furthermore,we established a new breast cancer survival prediction model based on cytoplasmic YAP1 expression. 展开更多

The leafy seadragon certainly is among evolution’s most“beautiful and wonderful”species aptly named for its extraordinary camouflage mimicking its coastal seaweed habitat.However,limited information is known about the genetic basis of its phenotypes and conspicuous camouflage.Here,we revealed genomic signatures of rapid evolution and positive selection in core genes related to its camouflage,which allowed us to predict population dynamics for this species.Comparative genomic analysis revealed that seadragons have the smallest olfactory repertoires among all ray-finned fishes,suggesting adaptations to the highly specialized habitat.Other positively selected and rapidly evolving genes that serve in bone development and coloration are highly expressed in the leaf-like appendages,supporting a recent adaptive shift in camouflage appendage formation.Knock-out of bmp6 results in dysplastic intermuscular bones with a significantly reduced number in zebrafish,implying its important function in bone formation.Global climate change-induced loss of seagrass beds now severely threatens the continued existence of this enigmatic species.The leafy seadragon has a historically small population size likely due to its specific habitat requirements that further exacerbate its vulnerability to climate change.Therefore,taking climate change-induced range shifts into account while developing future protection strategies. 展开更多

Colorectal cancer(CRC)is one of the most frequently diagnosed cancers and the leading cause of cancer-associated deaths.Epidemiological studies have shown that both genetic and environmental risk factors contribute to the development of CRC.Several metagenomic studies of CRC have identified gut dysbiosis as a fundamental risk factor in the evolution of colorectal malignancy.Although enormous efforts and substantial progresses have been made in understanding the relationship between human gut microbiome and CRC,the precise mechanisms involved remain elusive.Recent data have shown a direct causative role of the gut microbiome in DNA damage,inflammation,and drug resistance in CRC,suggesting that modulation of gut microbiome could act as a powerful tool in CRC prevention and therapy.Here,we provide an overview of the relationship between gut microbiome and CRC,and explore relevant mechanisms of colorectal tumorigenesis.We next highlight the potential of bacterial species as clinical biomarkers,as well as their roles in therapeutic response.Factors limiting the clinical translation of gut microbiome and strategies for resolving current challenges are further discussed. 展开更多

Vertebrates have developed various modes of reproduction,some of which are found in Teleosts.Over 300 species of the Syngnathidae(seahorses,pipefishes and seadragons)exhibit male pregnancies;the males have specialized brood pouches that provide immune protection,nourishment,and oxygen regulation.Chemokines play a vital role at the mammalian maternal–fetal interface;however,their functions in fish reproduction are unclear.This study revealed the evolutionary traits and potential functions of chemokine genes in 22 oviparous,ovoviviparous,and viviparous fish species through comparative genomic analyses.Our results showed that chemokine gene copy numbers and evolutionary rates vary among species with different modes of reproduction.Syngnathidae lost cxcl13 and cxcr5,which are involved in key receptor–ligand pairs for lymphoid organ development.Notably,Syngnathidae have site-specific mutations in cxcl12b and ccl44,suggesting immune function during gestation.Moreover,transcriptome analysis revealed that chemokine gene expression varies among Syngnathidae species with different types of brood pouches,suggesting adaptive variations in chemokine functions among seahorses and their relatives.Furthermore,challenge experiments on seahorse brood pouches revealed a joint immune function of chemokine genes during male pregnancy.This study provides insights into the evolutionary diversity of chemokine genes associated with different reproductive modes in fish. 展开更多

Sugarcane/soybean intercropping with reduced nitrogen addition is an important sustainable agricultural pattern that can alter soil ecological functions,thereby affecting straw decomposition in the soil.However,the mechanisms underlying changes in soil organic carbon(SOC)composition and microbial communities during straw decomposition under long-term intercropping with reduced nitrogen addition remain unclear.In this study,we conducted an in-situ microplot incubation experiment with^(13)C-labeled soybean straw residue addition in a two-factor(cropping pattern:sugarcane monoculture(MS)and sugarcane/soybean intercropping(SB);nitrogen addition levels:reduced nitrogen addition(N1)and conventional nitrogen addition(N2))long-term experimental field plot.The results showed that the SBN1 treatment significantly increased the residual particulate organic carbon(POC)and residual microbial biomass carbon(MBC)contents during straw decomposition,and the straw carbon in soil was mainly conserved as POC.Straw addition changed the structure and reduced the diversity of the soil microbial community,but microbial diversity gradually recovered with decomposition time.During straw decomposition,the intercropping pattern significantly increased the relative abundances of Firmicutes and Ascomycota.In addition,straw addition reduced microbial network complexity in the sugarcane/soybean intercropping pattern but increased it in the sugarcane monoculture pattern.Nevertheless,microbial network complexity remained higher in the SBN1 treatment than in the MSN1 treatment.In general,the SBN1 treatment significantly increased the diversity of microbial communities and the relative abundance of microorganisms associated with organic matter decomposition,and the changes in microbial communities were mainly driven by the residual labile SOC fractions.These findings suggest that more straw carbon can be sequestered in the soil under sugarcane/soybean intercropping with reduced nitrogen addition to maintain microbial diversity and contribute to the development of sustainable agriculture. 展开更多

In traditional Chinese medicine, Lonicerae Japonicae Flos is commonly used as anti-inflammatory, antiviral, and antipyretic herbal medicine, and geo-authentic herbs are believed to present the highest quality among all samples from different regions. To discuss the current situation and trend of geo-authentic Lonicerae Japonicae Flos, we searched Chinese Biomedicine Literature Database, Chinese Journal Full-text Database, Chinese Scientific Journal Full-text Database, Cochrane Central Register of Controlled Trials, Wanfang, and PubMed. We investigated all studies up to November 2015 pertaining to quality assessment, discrimination, pharmacological effects, planting or processing, or ecological system of geo-authentic Lonicerae Japonicae Flos. Sixty-five studies mainly discussing about chemical fingerprint, component analysis, planting and processing, discrimination between varieties, ecological system, pharmacological effects, and safety were systematically reviewed. By analyzing these studies, we found that the key points of geo-authentic Lonicerae Japonicae Flos research were quality and application. Further studies should focus on improving the quality by selecting the more superior of all varieties and evaluating clinical effectiveness. 展开更多
