Although specifi...Arboviral encephalitis is a group of animal and human illness that is mostly caused by several distinct families of viruses including orthobunya virus, phlebovirus, flaviviruses, and the alphaviruses. Although specific signs and symptoms vary by the type of central nervous system (CNS), initial signs and symptoms are very similar. Therefore rapid immunologic and molecular tools for differential diagnosis of arboviral encephalitis viruses are important for effective case management and control of the spread of encephalitis. The qRT-PCR assay, especially multiplex PCR, has the potential to produce considerable savings in time and resources in the laboratory detection. Meanwhile, the use of IC can prevent false negatives effectively by monitoring the processes of nucleic acid extraction and amplification. This report describes the development of a panel of internally controlled multiplex one-step real-time RT-PCR assays in which two virus specific-probe sets were used in the same reaction for the detection of 15 species arboviral encephalitis viruses: the comparative sensitivity of multiplex one-step qRT-PCR assays to single plex one-step qRT-PCR assays as well as one-step RT-PCR assays for detection of each viral species. And total of 150 human serum samples were detected to evaluate the multiplex one-step qRT-PCR assays. These multiplex one-step real-time RT-PCR assays with IC were evaluated in terms of sensitivity, linearity, precision, specificity, and also field samples including serum and vector. These assays can detect and differentiate arboviral encephalitis viruses by high throughput, sensitive, and specific way. It is useful for clinical management and outbreak control of arboviral encephalitis viruses and vector surveillance.展开更多

文摘Background:Colistin(polymyxin E)is a kind of peptide antibiotic which has been approved in animal production for the purposes of disease prevention,treatment,and growth promotion.However,the wide use of colistin in animal feed may accelerate the spread of colistin-resistance gene MCR-1 from animal production to human beings,and its residue in animal-origin food may also pose serious health hazards to humans.Thus,it is necessary to develop corresponding analytical methods to monitor the addition of colistin in animal feed and the colistin residue in animal-origin food.Results:A one-step enzyme-linked immunosorbent assay(ELISA)and a lateral flow immunochromatographic assay(LFIA)for colistin were developed based on a newly developed monoclonal antibody.The ELISA showed a 50%inhibition value(IC50)of 9.7 ng/m L with assay time less than 60 min,while the LFIA had a strip reader-based detection limit of 0.87 ng/m L in phosphate buffer with assay time less than 15 min.For reducing the non-specific adsorption of colistin onto sample vial,the components of sample extraction solution were optimized and proved to greatly improve the assay accuracy.The spiked recovery experiment showed that the recoveries of colistin from feed,milk and meat samples were in the range of 77.83%to 113.38%with coefficient of variations less than 13%by ELISA analysis and less than 18%by LFIA analysis,respectively.Furthermore,actual sample analysis indicated that the two immunoassays can produce results consistent with instrumental analysis.Conclusions:The developed assays can be used for rapid qualitative or quantitative detection of colistin in animal feed and food.
文摘Arboviral encephalitis is a group of animal and human illness that is mostly caused by several distinct families of viruses including orthobunya virus, phlebovirus, flaviviruses, and the alphaviruses. Although specific signs and symptoms vary by the type of central nervous system (CNS), initial signs and symptoms are very similar. Therefore rapid immunologic and molecular tools for differential diagnosis of arboviral encephalitis viruses are important for effective case management and control of the spread of encephalitis. The qRT-PCR assay, especially multiplex PCR, has the potential to produce considerable savings in time and resources in the laboratory detection. Meanwhile, the use of IC can prevent false negatives effectively by monitoring the processes of nucleic acid extraction and amplification. This report describes the development of a panel of internally controlled multiplex one-step real-time RT-PCR assays in which two virus specific-probe sets were used in the same reaction for the detection of 15 species arboviral encephalitis viruses: the comparative sensitivity of multiplex one-step qRT-PCR assays to single plex one-step qRT-PCR assays as well as one-step RT-PCR assays for detection of each viral species. And total of 150 human serum samples were detected to evaluate the multiplex one-step qRT-PCR assays. These multiplex one-step real-time RT-PCR assays with IC were evaluated in terms of sensitivity, linearity, precision, specificity, and also field samples including serum and vector. These assays can detect and differentiate arboviral encephalitis viruses by high throughput, sensitive, and specific way. It is useful for clinical management and outbreak control of arboviral encephalitis viruses and vector surveillance.

文摘Oxygen release and electrolyte decomposition under high voltage endlessly exacerbate interfacial ramifications and structu ral degradation of high energy-density Li-rich layered oxide(LLO),leading to voltage and capacity fading.Herein,the dual-strategy of Cr,B complex coating and local gradient doping is simultaneously achieved on LLO surface by a one-step wet chemical reaction at room temperature.Density functional theory(DFT)calculations prove that stable B-O and Cr-O bonds through the local gradient doping can significantly reduce the high-energy O 2p states of interfacial lattice O,which is also effective for the near-surface lattice O,thus greatly stabilizing the LLO surface,Besides,differential electrochemical mass spectrometry(DEMS)indicates that the Cr_(x)B complex coating can adequately inhibit oxygen release and prevents the migration or dissolution of transition metal ions,including allowing speedy Li^(+)migration,The voltage and capacity fading of the modified cathode(LLO-C_(r)B)are adequately suppressed,which are benefited from the uniformly dense cathode electrolyte interface(CEI)composed of balanced organic/inorganic composition.Therefore,the specific capacity of LLO-CrB after 200 cycles at 1C is 209.3 mA h g^(-1)(with a retention rate of 95.1%).This dual-strategy through a one-step wet chemical reaction is expected to be applied in the design and development of other anionic redox cathode materials.
文摘Succinylcholine(SC)is a widely used depolarizing muscle relaxant,but improper use can lead to arrhythmias and,in severe cases,pose a life-threatening risk.Additionally,some criminals exploit SC for illicit activities.Therefore,rapid SC detection is paramount for clinical practice and public safety.Currently,however,limited methods are available for the rapid detection of SC.A fluorescent indicator displacement assay sensor based on molecular recognition of an amide naphthotube was developed.This sensor enabled the rapid fluorescent detection of SC through competitive binding between SC and methylene blue with the amide naphthotube.The sensor exhibited exceptional sensitivity with a detection limit as low as 1.1μmol/L and a detection range of 1.1~60μmol/L,coupled with outstanding selectivity and robust stability.Furthermore,this sensor accurately determined SC levels in biological samples such as serum.In summary,this research provides a new solution for the rapid and accurate sensing of SC in complex matrices and offers new insights for the swift identification and detection of toxins.

文摘In this work,one-step growth models using hyperspectral imaging(HSI)(400-1000 nm)were successfully developed in order to estimate the microbial loads,minimum growth temperature(T_(min))and maximum specific growth rate(μ_(max))of Brochothrix thermosphacta in chilled beef at isothermal temperatures(4-25℃).Three different methods were compared for model development,particularly using(Model Ⅰ)the predicted microbial loads from partial least squares regression of the whole spectral variables;(Model Ⅱ)the selected spectral variables related to microbial loads;and(Model Ⅲ)the first principal scores of HSI spectra by principal component analysis.Consequently,Model Ⅰ showed the best ability to predict the microbial loads of B.thermosphacta,with the coefficient of determination(R_(v)^(2))and root mean square error in internal validation(RMSEV)of 0.921 and 0.498(lg(CFU/g)).The T_(min)(-12.32℃)andμmax can be well estimated with R^(2) and root mean square error(RMSE)of 0.971 and 0.276(lg(CFU/g)),respectively.The upward trend ofμmax with temperature was similar to that of the plate count method.HSI technique thus can be used as a simple method for one-step growth simulation of B.thermosphacta in chilled beef during storage.
文摘BACKGROUND Inflammatory bowel disease(IBD)is a common chronic intestinal inflammatory disease.High oxidative stress is a treatment target for IBD.Cerium oxide(CeO2)nanomaterials as nanozymes with antioxidant activity are potential drugs for the treatment of colitis.AIM To synthesize hollow cerium(H-CeO2)nanoparticles by one-step method and to validate the therapeutic efficacy of H-CeO2 in IBD.METHODS H-CeO2 was synthesized by one-step method and examined its characterization and nanoenzymatic activity.Subsequently,we constructed dextran sulfate so-dium(DSS)-induced colitis in mice to observe the effects of H-CeO2 on colonic inflammation.The effects of H-CeO2 on colon inflammation and reactive oxygen species(ROS)levels in IBD mice were detected by hematoxylin and eosin staining and dichlorofluorescein diacetate staining,respectively.Finally,the biological sa-fety of H-CeO2 on mice was evaluated by hematoxylin and eosin staining,blood routine,and blood biochemistry.RESULTS H-CeO2 nanoparticles prepared by the one-step method were uniform,monodi-sperse and hollow.H-CeO2 had a good ability to scavenge ROS,∙OH and∙OOH.H-CeO2 reduced DSS-induced decreases in body weight and colon length,colonic epithelial damage,inflammatory infiltration,and ROS accumulation.H-CeO2 administration reduced the disease activity index of DSS-induced animals from about 8 to 5.H-CeO2 had no significant effect on body weight,total platelet count,hemoglobin,white blood cell,and red blood cell counts in healthy mice.No significant damage to major organs was observed in healthy mice following H-CeO2 administration.CONCLUSION The one-step synthesis of H-CeO2 nanomaterials had good antioxidant activity,biosafety,and inhibited deve-lopment of DSS-induced IBD in mice by scavenging ROS.

文摘A solid,fast-dissolving sodium silicate was used as an alkaline activator.Granulated blast furnace slag(GGBS),metakaolin(MK),and steel slag(SS)were used as the cementious components to prepare a ternary composite cementitious material known as alkali-activated steel slag composite cementitious material(ASCM)by the"one-step method".The impacts of cementitious components,alkali activator modulus,and Na_(2)O%on the mechanical strength were investigated,and the hydration products and hydration kinetics of ASCM were analyzed.The experimental results reveal that XRD,FTIR,SEM,EDS,and exothermic heat of hydration show that when GGBS:MK:SS=60wt%:10wt%:30wt%,the activator modulus is 1.2,and the alkali content is 5.5wt%,the 28 d flexural strength of ASCM mortar is 12.6 MPa,and the compressive strength is 53.3 MPa,the hydration products consist of C-S-H gel/C-A-S-H gel,mullite(3Al_(2)O_(3)-2SiO_(2)),calcite(CaCO_(3)),quartz,etc.ASCM has a large initial hydration exotherm rate but a small cumulative exotherm.

文摘Ostreopsis cf.ovata is a marine benthic dinoflagellate in tropical and temperate seas and can produce potent toxic compounds.The existence of O.cf.ovata has been found in the Chinese coastal areas,but studies on its toxicity are very few.This study investigated the toxicity of the O.cf.ovata(TIO991)isolated from Weizhou Island in the South China Sea by using methanol and chloroform to extract toxic compounds from the algal cells cultured indoor.Experiments on mouse acute toxicity showed that the crude methanol extract(CME)of O.cf.ovata caused the death of mice in 16–18 min.Furthermore,CME inhibited the cell reproduction of human neuroblastoma cells(BE(2)-M17 cells)by Cell Counting Kit-8 with a dose-and time-effect relationship and caused cell death in the form of cell necrosis.We found that CME had strong hemolytic activity and was significantly inhibited by ouabain,indicating that CME might contain palytoxins.By contrast,the crude chloroform extract of O.cf.ovata was relatively weak in toxicity as obtained in our experiments on mouse acute toxicity,cytotoxicity,and hemolytic activity.This suggests that the algae may raise the potential threat to marine ecosystems and public health.

文摘Recombinant human growth hormone(rhGH)has been widely used for the treatment of disorders associated with GH deficiency and multiple clinical indications[1].Accurate determination of biological activity is essential in the development,registration,and quality control of rhGH pharmaceutical products[2].However,the existing in vivo bioassay procedure based on somatropin-induced weight gain in rats is complicated,and the use of a rat cell line-based approach(Nb2-11 bioassay),which measures the production of adenosine triphosphate(ATP)as a direct indicator of cell growth,has a low mechanism of action(MOA)relevance.Therefore,novel rhGH bioassays are still needed.To this end,we developed a reporter gene assay(RGA)based on the GH/insulin-like growth factor-1(IGF-1)axis.

文摘Background:Organ transplantation recipients encounter significant risks from acute or chronic infections that threaten graft survival.BK virus(BKV)and JC virus(JCV)are 2 prominent opportunistic infection viruses,and they may cause polyomavirus-associated nephropathy and graft kidney loss in patients who are in an immunosuppressed state after kidney transplantation.Hence,timely detection and sustained monitoring of the viral load are indispensable.However,the current diagnostic methods remain limited,and the development of new molecular detection technology is extremely urgent.Methods:The sequences and concentrations of clustered regularly interspaced short palindromic repeats(CRISPR)RNA(crRNA),the concentration of Cas13a,and the primers for recombinase polymerase amplification(RPA)were optimized for BKV and JCV detection.Next,a novel microfluidic dual-droplet chip was designed and fabricated,and it was integrated with CRISPR(ddCRISPR)to simultaneously qualitatively detect BKV and JCV.Subsequently,the ddCRISPR assay was verified using clinical samples.Then,a lateral flow strip combined with CRISPR(LFCRISPR)was developed for the detection of BKV and JCV in resource-limited settings.Results:A one-pot RPA-CRISPR reaction system was established and optimized for BKV and JCV detection.ddCRISPR can simultaneously and rapidly detect BKV and JCV with high sensitivity(10 copies/ml for BKV and 1 copy/ml for JCV),and provide absolute quantification,which is suitable for viral load detection and conducive to personalized and precise treatment for organ transplant recipients.LFCRISPR simplified the operational process through a simple visual readout,facilitating virus screening after organ transplantation.Conclusion:These platforms incorporate molecular testing into the transplantation treatment model,thereby reducing costs,prolonging the survival time of the graft,improving the clinical outcomes of postoperative management in kidney transplantation,and enhancing the patients’quality of life.
