Molecular docking is an important method for the research of protein-protein interaction and recognition. A protein can be considered as a network when the residues are treated as its nodes. With the contact energy between residues as link weight, a weighted residue network is constructed in this paper. Two weighted parameters (strength and weighted average nearest neighbors' degree) are introduced into this model at the same time. The stability of a protein is characterized by its strength. The global topological properties of the protein-protein complex are reflected by the weighted average nearest neighbors' degree. Based on this weighted network model and these two parameters, a new docking scoring function is proposed in this paper. The scoring and ranking for 42 systems' bound and unbounded docking results are performed with this new scoring function. Comparing the results obtained from this new scoring function with that from the pair potentials scoring function, we found that this new scoring function has a similar performance to the pair potentials on some items, and this new scoring function can get a better success rate. The calculation of this new scoring function is easy, and the result of its scoring and ranking is acceptable. This work can help us better understand the mechanisms of protein-protein interactions and recognition. 相似文献

Since the discovery of non-neuronal acetylcholine in the heart, this specific system has drawn scientific interest from many research fields, including cardiology, immunology, and pharmacology. This system, acquired by cardiomyocytes independent of the parasympathetic nervous system of the autonomic nervous system, helps us to understand unsolved issues in cardiac physiology and to realize that the system may be more pivotal for cardiac homeostasis than expected. However, it has been shown that the effects of this system may not be restricted to the heart, but rather extended to cover extra-cardiac organs. To this end, this system intriguingly influences brain function, specifically potentiating blood brain barrier function. Although the results reported appear to be unusual, this novel characteristic can provide us with another research interest and therapeutic application mode for central nervous system diseases. In this review, we discuss our recent studies and raise the possibility of application of this system as an adjunctive therapeutic modality. 相似文献

The phenomenon of phase inversion occurs in liquid‐liquid dispersions found in a variety of chemical engineering fields. From simple oil‐water mixtures to complex polymeric systems, the operating variables that affect this physical phenomenon are discussed in this work. The contribution on this matter by a large number of researchers is critically assessed, outlining both coherent and conflicting results. A detailed review of the mechanisms by which phase inversion takes place is also provided. While this subject has been studied for the past 50 years, this multivariate nonlinear process is not yet comprehensively understood, and this review article aims to describe the conclusions so far reached to provide insight for future research. 相似文献

A review of salt scaling: II. Mechanisms 总被引:2,自引:0,他引:2
Salt scaling is a major durability issue for concrete. Despite this, and an extensive research effort, the cause of this damage is unknown. Therefore, no means for preventing salt scaling can be identified. One of the primary reasons for this shortcoming is the lack of a critical review on the state of the research in this field. Such a compilation is presented in this series of articles. In Part I, the characteristics of salt scaling were outlined. In this article, proposed mechanisms are discussed, and their adequacy is judged based on their ability to account for the phenomenology. 相似文献

Developing corn hybrids with improved FA profiles is important in providing products with enhanced nutritional characteristics.
To support this effort, rapid screening methods are needed to track the various traits of interest. In using NIR methods,
calibrations are based on an assumed linear relationship between the concentration of the analyte of interest and the absorbance
of the sample. Although this point seems obvious, this linear relationship does not exist when using GC analysis as a reference
method for oleic acid content in ground corn kernels. In this case, the GC data provide a relative oleic acid content of the
oil and not of the grain from which the NIR spectrum is measured. A method of removing this nonlinearity by modeling the absolute
oleic acid content in the grain has been developed. The relative oleic acid content of the oil is then calculated from this
predicted absolute oleic acid value, and the total oil content of the grain is predicted from another calibration model. Significant
improvement in the model's predictive ability is demonstrated using this two-calibration model. 相似文献
