文摘Influenza is a significant global public health challenge,with seasonal epidemics imposing substantial burdens on healthcare systems and vulnerable populations,causing 3 to 5 million severe cases and 290,000 to 650,000 respiratory-related deaths worldwide each year[1].Vaccines are an effective means of preventing influenza.In recent years,China has made progress in vaccine development and immunization strategies.The population is recommended to receive influenza vaccines annually;however,their coverage remain suboptimal[2].The World Health Organization(WHO)highlights that all countries should consider implementing seasonal influenza immunization programs,with priority groups determined based on local epidemiological contexts.In alignment with the Immunization Agenda 2030,the use of seasonal influenza vaccines contributes to strengthening the life course of immunization and serves as a critical component for addressing influenza pandemics,as outlined in the WHO Global Influenza Strategy 2019-2030.
文摘Water scarcity in Khuzestan Province,Iran,has attracted growing concerns despite the region's abundant water resources.The province predominantly relies on surface water,prompting an assessment of groundwater's potential to supplement water supplies during surface water shortages.This study assesses the province's groundwater availability and quality under increased exploitation conditions.Between 2008 and 2018,data on groundwater quantity and quality were collected from 204 exploration wells and 70 piezometric wells across 19 aquifers.The analysis revealed that 53%of aquifers in the eastern and northeastern regions experienced declining groundwater levels.Hydrochemical assessments indicated low concentrations of major ions in the northeastern,while high levels were observed from the central region towards the southeast.These variations were attributed to agricultural and industrial activities,seawater intrusion,and the influences of evaporation and geological factors.The dominant hydrochemical facies identified were of the Ca-Cl type.Water quality classification showed that 48%of groundwater samples fell within the C4S4-C4S1 category,primarily in the western,central,and southern regions,while 27%were classified as C3S2,C3S1,and 25%as C2S1,mainly in the northern and eastern regions.The Irrigation WWater Quality(IWQ)index indicated that many samples were suitable for irrigation.Additionally,the analysis potable groundwater was primarily found in the northern,northeastern,and eastern aquifers,with quality declining toward the south.The study highlights that certain aquifers in the northern and eastern regions offer greater potential for sustainable groundwater exploitation during water shortages.These findings provide valuable insights for on how to implement effective land and water management strategies to mitigate future water crises.

文摘Emerging tick-borne viruses are posing an increasing health concern.However,there is limited knowledge about the distribution characteristics of tick virome in Yunnan Province,southwestern China,where it is distinguished by its diverse eco-climatic zones and rich biodiversity,making it a hotspot for studying tick-borne pathogens.The present study aimed to explore the diversity and ecological characteristics of tick virome in Yunnan Province,especially to identify novel potentially pathogenic viruses threatening human and vertebrate animals,and to investigate host-specific viral tropisms and their transmission characteristics.Using a meta-transcriptomic approach,the study analyzed the viromes of 448 individual ticks and approximately 10,000 eggs collected from nine counties with different hosts,altitudes and landscapes.The ticks encompassed eight species across four genera.The study focused on delineating virome diversity profiles,evaluating host-specific viral tropisms,and investigating potential transovarial transmission through viral contigs identification and Sanger sequencing.The study identified 53 viral families,revealing significant virome diversity and geographic and environmental specificity.Haemaphysalis and Ixodes ticks exhibited greater viral richness and abundance,with host taxonomy being a primary influencing factor.We determined 102 viral genomes encompassing 35 species,comprising 15 novel viruses identified when their RNAdependent RNA polymerase/DNA polymerase sequences exhibited<90% amino acid identity to known viruses.The novel vectors for vertebrate-related or potentially pathogenic viruses were also detected,thus providing new insights into transmission cycles.The evidence for transovarial transmission was reinforced by the absence of significant differences in Chuviridae and Nairoviridae families between female ticks and their eggs.These findings underscore the necessity of continuous surveillance to avert the spillover of emerging pathogens.

文摘The study reconstructs the Upper Devonian Domanik sedimentation conditions using geochemical studies.Domanik sediments,the subject of study,are being developed in Russia's Volga-Ural petroleum province.Core samples have been collected from the South Tatar arch and the Birskaya saddle,totaling four wells.Macroscopic description,optical microscopic petrographic examination,X-ray analysis,X-ray fluorescence analysis,inductively coupled plasma mass spectrometry(ICP-MS),simultaneous thermal analyses,scanning electronic microscopy(SEM),Rock-Eval pyrolytic studies,and correlation analysis were among the methods used in the study.Carbonate rocks,carbonate-siliceous rocks enriched with organic matter,and carbonate breccias are the main identified lithotypes.The predominant rock-forming mineral in carbonate-siliceous rocks enriched with organic matter is quartz(chalcedony)of authigenic genesis.The lack of co rrelation between organic matter concentration and quartz,as well as the results of simultaneous thermal studies and SEM,suggest that quartz is present in both biogenic and chemogenic forms.The proxies Cd/Mo and Co x Mn were used for proving variable hydrodynamic conditions in the Domanik sediments sea:sediments were deposited under both stationary and seasonal upwelling conditions.The major bioproductivity of the Domanik sea was also influenced by hydrothermal activity.The proxy(Fe+Mn)/Ti data and the results of the rock genesis evaluation using the Zn-Ni-Co triangle diagram confirm this.The presence of hydrothermal fluids not only improved primary production in the paleobasin,but it additionally provided silica,as evidenced by the strong relationship between silica and exhalation components in carbonate-siliceous rocks.Volcanic activity had a slight impact on Domanik sediment genesis.Anoxia and euxinia in the Domanik sea were indicated by proxy U/Th-TOC and V/CrTOC data,as well as behavior of U-EF and Mo-EF on the covariation plot,which influenced organic matter burial in the sediments.Simultaneously,the terrigenous intake was limited.Carbonate breccias,which are common in the Domanik sediments section,developed as a result of the gravitational transfer of carbonate fragments into the carbonate-siliceous material,which might be driven by earthquakes.
