However, the frequent occurrence of TCM-induced adverse reactions has hindered the modernization and internationalization of TCM, while attracting increasing attention from around the world. Unlike chemical drugs and biological agents, the difficulties involved in research on the toxicity and safety of TCM mainly include the complexity of its components and the unpredictability of drug–body interactions. Much of TCM, which has overall therapeutic effects, has the typical mechanisms of multiple components, multiple pathways, and multiple targets. While considering the gradualness and unpredictability of TCM toxicity, the ambiguity of toxicants and safe dosage, and individual differences during long-term TCM administration, we have systematically established key techniques for the toxicity assessment of TCM. These techniques mainly include TCM toxicity discovery in an early phase, based on a combination of drug toxicology genomics and metabolomics;methods to identify dose–toxicity relationships in TCM;and integrated techniques for the exploration of TCM interactions, such as fast-screening tests based on drug-metabolizing enzymes and receptor pathways. In particular, we have developed a new technical system for TCM safety evaluation using molecular toxicology, which has been validated well in research on TCM compatibility contraindication, quality control, and allergen discovery. The application of this key technical platform is introduced here in detail. This application includes model organisms, toxicant biomarkers, a magnetic suspension technique, and the application of network toxicology and computational toxicology in research on the toxicity of Fructus toosendan, Semen cassiae, Polygonum multiflorum, and Fructus psoraleae.展开更多

In this work, we have made a comprehensive evaluation of the performances of existingtop RNA secondary structure prediction methods, including five deep-learning (DL) based methods and five minimum freeenergy (MFE) based methods. First, we made a brief overview of these RNA secondary structure prediction methods.Afterwards, we built two rigorous test datasets consisting of RNAs with non-redundant sequences and comprehensivelyexamined the performances of the RNA secondary structure prediction methods through classifying the RNAs into differentlength ranges and different types. Our examination shows that the DL-based methods generally perform better thanthe MFE-based methods for RNAs with long lengths and complex structures, while the MFE-based methods can achievegood performance for small RNAs and some specialized MFE-based methods can achieve good prediction accuracy forpseudoknots. Finally, we provided some insights and perspectives in modeling RNA secondary structures.展开更多

Guinea fowl were divided into 5 batches, of which 3 batches received prophylactic medical treatment including plant decoctions, the 4th batch was followed by a medical prophylaxis program as a control group and the 5th batch considered as a negative control, has not received any prophylactic treatment. The results showed that a mortality rate of 25% for the reference lot and two other batches which received plant decoctions （Euphorbia poissonii or Khaya senegalensis） were recorded against a rate of 87.5% in the batch of guinea fowl which received the decoction of Pteleopsis suberosa. Meanwhile, regardless of weight growth, daily average gain （GMQ） or food consumption, no significant difference was observed （p 〉 0.05） between the guinea fowl that received a baseline health monitoring and those having taken the decoction orE. poissonii. On the other hand, the values recorded in these two batches of guinea fowl differed statistically from those in the guinea fowl that received the decoction of K. senegalensis. Although the decoction of K. senegalensis has a protective effect in guinea fowl, the growth of guinea fowl has been slowed down. On the basis of these results, it appears that two endogenous practices tested （K. senegalensis or E. poissonii） have positive effects. However, it would be desirable to carry out a toxicity test in order to determine the recommended doses.展开更多

文摘We present an improved digital image processing(DIP)method to calculate the widths of single slits.Different from the traditional laser Fraunhofer diffraction experiment in college physical experiments,by performing fast Fourier transform,inverse fast Fourier transform and the nonlinear leastsquare fitting on the diffraction pattern taken by a camera,the DIP method can quickly return an analytic expression,whose period is used to calculate widths of single slits.By comparing the measured results by the DIP method and the successional difference(SD)method,we find that for a single slit whose width is 60372μm,the DIP method is more accurate.Experimental results show that for single slits with widths between 40μm and 160μm,the relative error of the DIP method is less than 2.78%.Also,the DIP method can be used to measure the diameter of filament and fibres online in real time.

文摘RNAs have important biological functions and the functions of RNAs are generally coupled to their structures, especiallytheir secondary structures. In this work, we have made a comprehensive evaluation of the performances of existingtop RNA secondary structure prediction methods, including five deep-learning (DL) based methods and five minimum freeenergy (MFE) based methods. First, we made a brief overview of these RNA secondary structure prediction methods.Afterwards, we built two rigorous test datasets consisting of RNAs with non-redundant sequences and comprehensivelyexamined the performances of the RNA secondary structure prediction methods through classifying the RNAs into differentlength ranges and different types. Our examination shows that the DL-based methods generally perform better thanthe MFE-based methods for RNAs with long lengths and complex structures, while the MFE-based methods can achievegood performance for small RNAs and some specialized MFE-based methods can achieve good prediction accuracy forpseudoknots. Finally, we provided some insights and perspectives in modeling RNA secondary structures.
文摘Objectives:This study examined the hypothesis that whether any significant differences exist or not in individual temperament and somatotype components in young athletes.Methods:The cross-sectional study was carried out with 202 male athletes(age=23 years±2.7,mean±SE).They were categorized into four groups according to their temperaments by using a questionnaire.Also,the Heath-Carter method was applied to estimate the somatotype components.One-Way ANOVA followed by Scheffe’s tests was organized(p<0.05)for data analysis.Results:In this research,the highest mesomorphy,ectomorphy and endomorphy components were observed in the Blood,Yellow Bile and Phlegm temperaments,respectively with means of 6.1±0.28,3.9±0.11,and 5.9±0.32.Also,a significant difference was observed between Blood temperament and mesomorphy component(p<0.001)but Blood temperament had insignificant differences with other studied somatotype components(p>0.05).Ectomorphy and mesomorphy components significantly differ among Yellow Bile temperament(p<0.05),while an insignificant difference was found between Yellow Bile temperament and endomorphy component(p>0.05).Significant differences also were showed between Black Bile temperament and all somatotype components(p<0.05).Among Phlegm temperament and endomorphy component was a significant difference(p<0.001),but there were no significant differences between the Phlegm temperament and the other two somatotype components(p>0.05).Conclusions:Given the importance of body type in sports performance,current findings suggest that coaches should be aware of the individual temperaments which could serve as a guide to design special training schedules for athletes.
文摘A study on the evaluation of the effectiveness of three traditional methods of protecting guinea fowl from mortality was carried out at CRA-SS （Centre de Recherche Agronomique de la Savane S6che） in northem Togo. Guinea fowl were divided into 5 batches, of which 3 batches received prophylactic medical treatment including plant decoctions, the 4th batch was followed by a medical prophylaxis program as a control group and the 5th batch considered as a negative control, has not received any prophylactic treatment. The results showed that a mortality rate of 25% for the reference lot and two other batches which received plant decoctions （Euphorbia poissonii or Khaya senegalensis） were recorded against a rate of 87.5% in the batch of guinea fowl which received the decoction of Pteleopsis suberosa. Meanwhile, regardless of weight growth, daily average gain （GMQ） or food consumption, no significant difference was observed （p 〉 0.05） between the guinea fowl that received a baseline health monitoring and those having taken the decoction orE. poissonii. On the other hand, the values recorded in these two batches of guinea fowl differed statistically from those in the guinea fowl that received the decoction of K. senegalensis. Although the decoction of K. senegalensis has a protective effect in guinea fowl, the growth of guinea fowl has been slowed down. On the basis of these results, it appears that two endogenous practices tested （K. senegalensis or E. poissonii） have positive effects. However, it would be desirable to carry out a toxicity test in order to determine the recommended doses.
