Those aliasing signals make the receiving ability of the signal receiver worse, the signal processing ability weaker,and the anti-interference ability of the communication system lower. Aiming at the above problems, to save communication resources and improve communication efficiency, and considering the irregularity of interference signals, the underdetermined blind separation technology can effectively deal with the problem of interference sensing and signal reconstruction in this scenario. In order to improve the stability of source signal separation and the security of information transmission, a greedy optimization algorithm can be executed. At the same time, to improve network information transmission efficiency and prevent algorithms from getting trapped in local optima, delete low-energy points during each iteration process. Ultimately, simulation experiments validate that the algorithm presented in this paper enhances both the transmission efficiency of the network transmission system and the security of the communication system, achieving the process of interference sensing and signal reconstruction in the LEO satellite communication system.展开更多

Oral squamous cell carcinoma (OSCC), a representative hypoxic tumor, has a heterogeneous internal metabolic environment. To clarify the relationship between different metabolic regions and the tumor immune microenvironment (TME) in OSCC, Single cell (SC) and spatial transcriptomics (ST) sequencing of OSCC tissues were performed. The proportion of TME in the ST data was obtained through SPOTlight deconvolution using SC and GSE103322 data. The metabolic activity of each spot was calculated using scMetabolism,and k-means clustering was used to classify all spots into hyper-, normal-, or hypometabolic regions. CD4T cell infiltration and TGF-βexpression is higher in the hypermetabolic regions than in the others. Through CellPhoneDB and NicheNet cell-cell communication analysis, it was found that in the hypermetabolic region, fibroblasts can utilize the lactate produced by glycolysis of epithelial cells to transform into inflammatory cancer-associated fibroblasts (iCAFs), and the increased expression of HIF1A in iCAFs promotes the transcriptional expression of CXCL12. The secretion of CXCL12 recruits regulatory T cells (Tregs), leading to Treg infiltration and increased TGF-β secretion in the microenvironment and promotes the formation of a tumor immunosuppressive microenvironment. This study delineates the coordinate work axis of epithelial cells-iCAFs-Tregs in OSCC using SC, ST and TCGA bulk data, and highlights potential targets for therapy.展开更多

This paper proposes a domain question-answering algorithm based on the CLIP mechanism to improve the accuracy and efficiency of interaction. First, this paper reviewed relevant technologies involved in the question-answering field. Then, the question-answering model based on the CLIP mechanism was produced, including its design, implementation, and optimization. It also described the construction process of the specific domain knowledge graph, including graph design, data collection and processing, and graph construction methods. The paper compared the performance of the proposed algorithm with classic question-answering algorithms BiDAF, R-Net, and XLNet models, using a military domain dataset. The experimental results show that the proposed algorithm has advanced performance, with an F1 score of 84.6% on the constructed military knowledge graph test set, which is at least 1.5% higher than other models. We conduct a detailed analysis of the experimental results, which illustrates the algorithm’s advantages in accuracy and efficiency, as well as its potential for further improvement. These findings demonstrate the practical application potential of the proposed algorithm in the military domain.展开更多

identities of antihepatoma...BACKGROUND Centipedes have been used to treat tumors for hundreds of years in China.However,current studies focus on antimicrobial and anticoagulation agents rather than tumors.The molecular identities of antihepatoma bioactive components in centipedes have not yet been extensively investigated.It is a challenge to isolate and characterize the effective components of centipedes due to limited peptide purification technologies for animal-derived medicines.AIM To purify,characterize,and synthesize the bioactive components with the strongest antihepatoma activity from centipedes and determine the antihepatoma mechanism.METHODS An antihepatoma peptide(scolopentide)was isolated and identified from the centipede scolopendra subspinipes mutilans using a combination of enzymatic hydrolysis,a Sephadex G-25 column,and two steps of high-performance liquid chromatography(HPLC).Additionally,the CCK8 assay was used to select the extracted fraction with the strongest antihepatoma activity.The molecular weight of the extracted scolopentide was characterized by quadrupole time of flight mass spectrometry(QTOF MS),and the sequence was matched by using the Mascot search engine.Based on the sequence and molecular weight,scolopentide was synthesized using solid-phase peptide synthesis methods.The synthetic scolopentide was confirmed by MS and HPLC.The antineoplastic effect of extracted scolopentide was confirmed by CCK8 assay and morphological changes again in vitro.The antihepatoma effect of synthetic scolopentide was assessed by the CCK8 assay and Hoechst staining in vitro and tumor volume and tumor weight in vivo.In the tumor xenograft experiments,qualified model mice(male 5-week-old BALB/c nude mice)were randomly divided into 2 groups(n=6):The scolopentide group(0.15 mL/d,via intraperitoneal injection of synthetic scolopentide,500 mg/kg/d)and the vehicle group(0.15 mL/d,via intraperitoneal injection of normal saline).The mice were euthanized by cervical dislocation after 14 d of continuous treatment.Mechanistically,flow cytometry was conducted to evaluate the apoptosis rate of HepG2 cells after treatment with extracted scolopentide in vitro.A Hoechst staining assay was also used to observe apoptosis in HepG2 cells after treatment with synthetic scolopentide in vitro.CCK8 assays and morphological changes were used to compare the cytotoxicity of synthetic scolopentide to liver cancer cells and normal liver cells in vitro.Molecular docking was performed to clarify whether scolopentide tightly bound to death receptor 4(DR4)and DR5.qRT-PCR was used to measure the mRNA expression of DR4,DR5,fas-associated death domain protein(FADD),Caspase-8,Caspase-3,cytochrome c(Cyto-C),B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),x-chromosome linked inhibitor-of-apoptosis protein and Cellular fas-associated death domain-like interleukin-1βconverting enzyme inhibitory protein in hepatocarcinoma subcutaneous xenograft tumors from mice.Western blot assays were used to measure the protein expression of DR4,DR5,FADD,Caspase-8,Caspase-3,and Cyto-C in the tumor tissues.The reactive oxygen species(ROS)of tumor tissues were tested.RESULTS In the process of purification,characterization and synthesis of scolopentide,the optimal enzymatic hydrolysis conditions(extract ratio:5.86%,IC_(50):0.310 mg/mL)were as follows:Trypsin at 0.1 g(300 U/g,centipede-trypsin ratio of 20:1),enzymolysis temperature of 46°C,and enzymolysis time of 4 h,which was superior to freeze-thawing with liquid nitrogen(IC_(50):3.07 mg/mL).A peptide with the strongest antihepatoma activity(scolopentide)was further purified through a Sephadex G-25 column(obtained A2)and two steps of HPLC(obtained B5 and C3).The molecular weight of the extracted scolopentide was 1018.997 Da,and the peptide sequence was RAQNHYCK,as characterized by QTOF MS and Mascot.Scolopentide was synthesized in vitro with a qualified molecular weight(1018.8 Da)and purity(98.014%),which was characterized by MS and HPLC.Extracted scolopentide still had an antineoplastic effect in vitro,which inhibited the proliferation of Eca-109(IC_(50):76.27μg/mL),HepG2(IC_(50):22.06μg/mL),and A549(IC_(50):35.13μg/mL)cells,especially HepG2 cells.Synthetic scolopentide inhibited the proliferation of HepG2 cells(treated 6,12,and 24 h)in a concentration-dependent manner in vitro,and the inhibitory effects were the strongest at 12 h(IC_(50):208.11μg/mL).Synthetic scolopentide also inhibited the tumor volume(Vehicle vs Scolopentide,P=0.0003)and weight(Vehicle vs Scolopentide,P=0.0022)in the tumor xenograft experiment.Mechanistically,flow cytometry suggested that the apoptosis ratios of HepG2 cells after treatment with extracted scolopentide were 5.01%(0μg/mL),12.13%(10μg/mL),16.52%(20μg/mL),and 23.20%(40μg/mL).Hoechst staining revealed apoptosis in HepG2 cells after treatment with synthetic scolopentide in vitro.The CCK8 assay and morphological changes indicated that synthetic scolopentide was cytotoxic and was significantly stronger in HepG2 cells than in L02 cells.Molecular docking suggested that scolopentide tightly bound to DR4 and DR5,and the binding free energies were-10.4 kcal/mol and-7.1 kcal/mol,respectively.In subcutaneous xenograft tumors from mice,quantitative real-time polymerase chain reaction and western blotting suggested that scolopentide activated DR4 and DR5 and induced apoptosis in SMMC-7721 Liver cancer cells by promoting the expression of FADD,caspase-8 and caspase-3 through a mitochondria-independent pathway.CONCLUSION Scolopentide,an antihepatoma peptide purified from centipedes,may inspire new antihepatoma agents.Scolopentide activates DR4 and DR5 and induces apoptosis in liver cancer cells through a mitochondria-independent pathway.展开更多

CPc GAN utilizes a discriminator to calculate the divergence between the predicted downlink channel state information(CSI) and the real sample distributions under a conditional constraint that is previous uplink CSI. The generator of CPcGAN learns the function relationship between the conditional constraint and the predicted downlink CSI and reduces the divergence between predicted CSI and real CSI.The capability of CPcGAN fitting data distribution can capture the time-varying and multipath characteristics of the channel well. Considering the propagation characteristics of real channel, we further develop a channel prediction error indicator to determine whether the generator reaches the best state. Simulations show that the CPcGAN can obtain higher prediction accuracy and lower system bit error rate than the existing methods under the same user speeds.展开更多

文摘Tumor progression is closely related to tumor tissue metabolism and reshaping of the microenvironment. Oral squamous cell carcinoma (OSCC), a representative hypoxic tumor, has a heterogeneous internal metabolic environment. To clarify the relationship between different metabolic regions and the tumor immune microenvironment (TME) in OSCC, Single cell (SC) and spatial transcriptomics (ST) sequencing of OSCC tissues were performed. The proportion of TME in the ST data was obtained through SPOTlight deconvolution using SC and GSE103322 data. The metabolic activity of each spot was calculated using scMetabolism,and k-means clustering was used to classify all spots into hyper-, normal-, or hypometabolic regions. CD4T cell infiltration and TGF-βexpression is higher in the hypermetabolic regions than in the others. Through CellPhoneDB and NicheNet cell-cell communication analysis, it was found that in the hypermetabolic region, fibroblasts can utilize the lactate produced by glycolysis of epithelial cells to transform into inflammatory cancer-associated fibroblasts (iCAFs), and the increased expression of HIF1A in iCAFs promotes the transcriptional expression of CXCL12. The secretion of CXCL12 recruits regulatory T cells (Tregs), leading to Treg infiltration and increased TGF-β secretion in the microenvironment and promotes the formation of a tumor immunosuppressive microenvironment. This study delineates the coordinate work axis of epithelial cells-iCAFs-Tregs in OSCC using SC, ST and TCGA bulk data, and highlights potential targets for therapy.

文摘The equilibrium configuration of a solid strange star in the final inspiral phase with another compact object is generally discussed,and the starquake-related issue is revisited,for a special purpose to understand the precursor emission of binary compact star merger events(e.g.,that of GRB211211A).As the binary system inspirals inward due to gravitational wave radiation,the ellipticity of the solid strangeon star increases due to the growing tidal field of its compact companion.Elastic energy is hence accumulated during the inspiral stage which might trigger a starquake before the merger when the energy exceeds a critical value.The energy released during such starquakes is calculated and compared to the precursor observation of GRB211211 A.The result shows that the energy might be insufficient for binary strangeon-star case unless the entire solid strangeon star shatters,and hence favors a black hole-strangeon star scenario for GRB211211A.The timescale of the precursor as well as the frequency of the observed quasi-periodic-oscillation have also been discussed in the starquake model.

文摘We report the results of a search for radio pulsars in five supernova remnants(SNRs)with the FAST telescope.The observations were made using the 19-beam receiver in“snapshot”mode.The integration time for each pointing was 10 min.We discovered a new pulsar,PSR J1845–0306,which has a spin period of 983.6 ms and a dispersion measure of 444.6±2.0 cm^(−3)·pc,in observations of SNR G29.6+0.1.To judge the association between the pulsar and the SNR,further verification is needed.We also re-detected some known pulsars in the data from SNRs G29.6+0.1 and G29.7–0.3.No pulsars were detected in the observations of the other three SNRs.

文摘Background:Nonalcoholic fatty liver disease(NAFLD)is a chronic condition characterized by a progressive decline in liver function,leading to disruptions in liver integrity and metabolic function,resulting in lipid deposition and excessive accumulation of extracellular matrix(ECM).The pathogenesis of NAFLD is complex and not yet fully understood,contributing to the absence of specific therapeutic strategies.Peroxisome proliferator-activated receptor gamma(PPARγ)is a ligand-activated transcription factor pivotal in regulating lipid and glucose metabolism.However,the impacts of PPARγon NAFLD remains insufficiently explored.Thus,this study aimed to investigate the role of PPARγin NAFLD and its underlying molecular mechanisms.Methods:Chemical detection kits were utilized to quantify collagen content,alanine aminotransferase(ALT),and aspartate aminotransferase(AST)level variations.Quantitative real-time polymerase chain reaction(qRT-PCR)was employed to assess alterations in extracellular matrix-related genes and inflammatory response genes in liver tissue and HepG2 cells,while western blotting was conducted to analyze the levels of both PPARγand the TGF-β/Smad signaling pathway.Results:Our findings unveiled significantly reduced PPARγexpression in a rat model of NAFLD,leading to subsequent activation of the TGF-β/Smad signaling pathway.Furthermore,PPARγactivation effectively mitigated NAFLD progression by inhibiting inflammation and fibrosis-related gene expression and collagen production.On a cellular level,PPARγactivation was found to inhibit the expression of extracellular matrix-related genes such as matrix metalloproteinase 2(MMP2)and matrix metalloproteinase 9(MMP9),along with inflammatory response genes interleukin(IL)-1βand IL-6.Additionally,PPARγactivation led to a significant decrease in the levels of ALT and AST.At the molecular level,PPARγnotably down-regulated the TGF-β/Smad signaling pathway,which is known to promote liver fibrosis.Conclusion:These groundbreaking findings underscore PPARγactivation as a promising therapeutic approach to delay NAFLD progression by targeting the TGF-β/Smad signaling pathway in hepatic cells.This highlights the potential of PPARγas a promising therapeutic target for NAFLD management in clinical settings.
文摘Research on specific domain question-answering technology has become important with the increasing demand for intelligent question-answering systems. This paper proposes a domain question-answering algorithm based on the CLIP mechanism to improve the accuracy and efficiency of interaction. First, this paper reviewed relevant technologies involved in the question-answering field. Then, the question-answering model based on the CLIP mechanism was produced, including its design, implementation, and optimization. It also described the construction process of the specific domain knowledge graph, including graph design, data collection and processing, and graph construction methods. The paper compared the performance of the proposed algorithm with classic question-answering algorithms BiDAF, R-Net, and XLNet models, using a military domain dataset. The experimental results show that the proposed algorithm has advanced performance, with an F1 score of 84.6% on the constructed military knowledge graph test set, which is at least 1.5% higher than other models. We conduct a detailed analysis of the experimental results, which illustrates the algorithm’s advantages in accuracy and efficiency, as well as its potential for further improvement. These findings demonstrate the practical application potential of the proposed algorithm in the military domain.

文摘Wellbore instability,especially drilling with water-based drilling fluids(WBDFs)in complex shale for-mations,is a critical challenge for oil and gas development.The purpose of this paper is to study the feasibility of using hydrophobically modified silica nanoparticle(HMN)to enhance the comprehensive performance of WBDFs in the Xinjiang Oilfield,especially the anti-collapse performance.The effect of HMN on the overall performance of WBDFs in the Xinjiang Oilfield,including inhibition,plugging,lu-bricity,rheology,and filtration loss,was studied with a series of experiments.The mechanism of HMN action was studied by analyzing the changes of shale surface structure and chemical groups,wettability,and capillary force.The experimental results showed that HMN could improve the performance of WBDFs in the Xinjiang Oilfeld to inhibit the hydration swelling and dispersion of shale.The plugging and lubrication performance of the WBDFs in the Xinjiang Oilfield were also enhanced with HMN based on the experimental results.HMN had less impact on the rheological and filtration performance of the WBDFs in the Xinjiang Oilfield.In addition,HMN significantly prevented the decrease of shale strength.The potential mechanism of HMN was as follows.The chemical composition and structure of the shale surface were altered due to the adsorption of HMN driven by electrostatic attraction.Changes of the shale surface resulted in significant wettability transition.The capillary force of the shale was converted from a driving force of water into the interior to a resistance.In summary,hydrophobic nanoparticles presented afavorable application potential for WBDFs.

文摘BACKGROUND Centipedes have been used to treat tumors for hundreds of years in China.However,current studies focus on antimicrobial and anticoagulation agents rather than tumors.The molecular identities of antihepatoma bioactive components in centipedes have not yet been extensively investigated.It is a challenge to isolate and characterize the effective components of centipedes due to limited peptide purification technologies for animal-derived medicines.AIM To purify,characterize,and synthesize the bioactive components with the strongest antihepatoma activity from centipedes and determine the antihepatoma mechanism.METHODS An antihepatoma peptide(scolopentide)was isolated and identified from the centipede scolopendra subspinipes mutilans using a combination of enzymatic hydrolysis,a Sephadex G-25 column,and two steps of high-performance liquid chromatography(HPLC).Additionally,the CCK8 assay was used to select the extracted fraction with the strongest antihepatoma activity.The molecular weight of the extracted scolopentide was characterized by quadrupole time of flight mass spectrometry(QTOF MS),and the sequence was matched by using the Mascot search engine.Based on the sequence and molecular weight,scolopentide was synthesized using solid-phase peptide synthesis methods.The synthetic scolopentide was confirmed by MS and HPLC.The antineoplastic effect of extracted scolopentide was confirmed by CCK8 assay and morphological changes again in vitro.The antihepatoma effect of synthetic scolopentide was assessed by the CCK8 assay and Hoechst staining in vitro and tumor volume and tumor weight in vivo.In the tumor xenograft experiments,qualified model mice(male 5-week-old BALB/c nude mice)were randomly divided into 2 groups(n=6):The scolopentide group(0.15 mL/d,via intraperitoneal injection of synthetic scolopentide,500 mg/kg/d)and the vehicle group(0.15 mL/d,via intraperitoneal injection of normal saline).The mice were euthanized by cervical dislocation after 14 d of continuous treatment.Mechanistically,flow cytometry was conducted to evaluate the apoptosis rate of HepG2 cells after treatment with extracted scolopentide in vitro.A Hoechst staining assay was also used to observe apoptosis in HepG2 cells after treatment with synthetic scolopentide in vitro.CCK8 assays and morphological changes were used to compare the cytotoxicity of synthetic scolopentide to liver cancer cells and normal liver cells in vitro.Molecular docking was performed to clarify whether scolopentide tightly bound to death receptor 4(DR4)and DR5.qRT-PCR was used to measure the mRNA expression of DR4,DR5,fas-associated death domain protein(FADD),Caspase-8,Caspase-3,cytochrome c(Cyto-C),B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),x-chromosome linked inhibitor-of-apoptosis protein and Cellular fas-associated death domain-like interleukin-1βconverting enzyme inhibitory protein in hepatocarcinoma subcutaneous xenograft tumors from mice.Western blot assays were used to measure the protein expression of DR4,DR5,FADD,Caspase-8,Caspase-3,and Cyto-C in the tumor tissues.The reactive oxygen species(ROS)of tumor tissues were tested.RESULTS In the process of purification,characterization and synthesis of scolopentide,the optimal enzymatic hydrolysis conditions(extract ratio:5.86%,IC_(50):0.310 mg/mL)were as follows:Trypsin at 0.1 g(300 U/g,centipede-trypsin ratio of 20:1),enzymolysis temperature of 46°C,and enzymolysis time of 4 h,which was superior to freeze-thawing with liquid nitrogen(IC_(50):3.07 mg/mL).A peptide with the strongest antihepatoma activity(scolopentide)was further purified through a Sephadex G-25 column(obtained A2)and two steps of HPLC(obtained B5 and C3).The molecular weight of the extracted scolopentide was 1018.997 Da,and the peptide sequence was RAQNHYCK,as characterized by QTOF MS and Mascot.Scolopentide was synthesized in vitro with a qualified molecular weight(1018.8 Da)and purity(98.014%),which was characterized by MS and HPLC.Extracted scolopentide still had an antineoplastic effect in vitro,which inhibited the proliferation of Eca-109(IC_(50):76.27μg/mL),HepG2(IC_(50):22.06μg/mL),and A549(IC_(50):35.13μg/mL)cells,especially HepG2 cells.Synthetic scolopentide inhibited the proliferation of HepG2 cells(treated 6,12,and 24 h)in a concentration-dependent manner in vitro,and the inhibitory effects were the strongest at 12 h(IC_(50):208.11μg/mL).Synthetic scolopentide also inhibited the tumor volume(Vehicle vs Scolopentide,P=0.0003)and weight(Vehicle vs Scolopentide,P=0.0022)in the tumor xenograft experiment.Mechanistically,flow cytometry suggested that the apoptosis ratios of HepG2 cells after treatment with extracted scolopentide were 5.01%(0μg/mL),12.13%(10μg/mL),16.52%(20μg/mL),and 23.20%(40μg/mL).Hoechst staining revealed apoptosis in HepG2 cells after treatment with synthetic scolopentide in vitro.The CCK8 assay and morphological changes indicated that synthetic scolopentide was cytotoxic and was significantly stronger in HepG2 cells than in L02 cells.Molecular docking suggested that scolopentide tightly bound to DR4 and DR5,and the binding free energies were-10.4 kcal/mol and-7.1 kcal/mol,respectively.In subcutaneous xenograft tumors from mice,quantitative real-time polymerase chain reaction and western blotting suggested that scolopentide activated DR4 and DR5 and induced apoptosis in SMMC-7721 Liver cancer cells by promoting the expression of FADD,caspase-8 and caspase-3 through a mitochondria-independent pathway.CONCLUSION Scolopentide,an antihepatoma peptide purified from centipedes,may inspire new antihepatoma agents.Scolopentide activates DR4 and DR5 and induces apoptosis in liver cancer cells through a mitochondria-independent pathway.

文摘In this paper, a time-varying channel prediction method based on conditional generative adversarial network(CPcGAN) is proposed for time division duplexing/frequency division duplexing(TDD/FDD) systems. CPc GAN utilizes a discriminator to calculate the divergence between the predicted downlink channel state information(CSI) and the real sample distributions under a conditional constraint that is previous uplink CSI. The generator of CPcGAN learns the function relationship between the conditional constraint and the predicted downlink CSI and reduces the divergence between predicted CSI and real CSI.The capability of CPcGAN fitting data distribution can capture the time-varying and multipath characteristics of the channel well. Considering the propagation characteristics of real channel, we further develop a channel prediction error indicator to determine whether the generator reaches the best state. Simulations show that the CPcGAN can obtain higher prediction accuracy and lower system bit error rate than the existing methods under the same user speeds.

文摘This study investigates mental health literacy among young and middle-aged urban and rural residents and the differences in mental health literacy,perceived social support and subjective well-being.From January to February 2022,620 participants(320 rural and 300 urban residents)from three provinces of China were selected by con-venience sampling.A general data questionnaire,mental health literacy scale,perceived social support scale and subjective well-being scale were administered.The mental health literacy scores of urban residents were 3.34±0.57 and those of rural residents were 2.73±0.79.The results of multiple regression analysis showed that the mental health literacy scores of rural residents were more significant than those of urban residents in terms of sex and age,while urban residents’mental health literacy scores were more significant than those of rural resi-dents in terms of monthly income.Mental health literacy,perceived social support and subjective well-being of young and middle-aged urban and rural residents were all positively correlated(P<0.01).While the level of mental health literacy is better among urban residents than rural residents,perceived social support plays a partial mediating role between mental health literacy and subjective well-being of both urban and rural residents,and should be the focus of researchers seeking to improve the level of well-being of residents.

文摘Video-based action recognition is becoming a vital tool in clinical research and neuroscientific study for disorder detection and prediction.However,action recognition currently used in non-human primate(NHP)research relies heavily on intense manual labor and lacks standardized assessment.In this work,we established two standard benchmark datasets of NHPs in the laboratory:Monkeyin Lab(Mi L),which includes 13 categories of actions and postures,and MiL2D,which includes sequences of two-dimensional(2D)skeleton features.Furthermore,based on recent methodological advances in deep learning and skeleton visualization,we introduced the Monkey Monitor Kit(Mon Kit)toolbox for automatic action recognition,posture estimation,and identification of fine motor activity in monkeys.Using the datasets and Mon Kit,we evaluated the daily behaviors of wild-type cynomolgus monkeys within their home cages and experimental environments and compared these observations with the behaviors exhibited by cynomolgus monkeys possessing mutations in the MECP2 gene as a disease model of Rett syndrome(RTT).Mon Kit was used to assess motor function,stereotyped behaviors,and depressive phenotypes,with the outcomes compared with human manual detection.Mon Kit established consistent criteria for identifying behavior in NHPs with high accuracy and efficiency,thus providing a novel and comprehensive tool for assessing phenotypic behavior in monkeys.
