目的研究正常人膀胱中细胞突触及其构成蛋白连接蛋白(Cx)是否存在。方法对6例全膀胱切除患者平滑肌用透射电子显微镜,冷冻爆裂电镜,逆转录聚合酶链反应(RT-PCR),免疫组化等方法进行研究。结果电镜结果显示膀胱平滑肌存在细胞突触,但这些细胞突触较小、形态不规律。RT-PCR 结果显示所有的样本均扩增出2个片段,大小分别为300 bp 和200 bp,测序结果显示它与已发表的 Cx45一致。荧光免疫组化显示大多数逼尿肌存在 Cx45的免疫信号。结论非梗阻性人膀胱平滑肌细胞是通过细胞突触进行电耦合的。

The Origin of Gravity—An Attempt to Answer this Question with the Help of existing Concepts

引用

Journal of Applied Mathematics and Physics 2017年第7期5卷 1440-1461页

作者： hubert J. Veringa emeritus Professor at eindhoven University Eindhoven The Netherlands

In this document an attempt is made to explain the origin of gravity. The basis for the analysis is a merger of Quantum theory and Relativity. Nowhere in the analysis there is any need to deviate from well proven and successful concepts of both theories and rules of calculation, and no exotic new particles will have to be introduced. By doing so it is demonstrated that, next to its local interactions of a multi-particle system, the Schrödinger equation leads to pairs of two and only two members. This solution is used as the invariant term in the “Klein-Gordon” equation which finally leads to gravitational interactions between members of the pairs. With this particular solution for the quantum-mechanical wave function, it is found that gravity is a second order effect operating over a long range. In this document it is tried to give a complete and consistent account of all steps that have been taken in the derivation of the classical Newton’s law. Further, the document emphasizes precise justification of some of the basic assumptions made and how it works out on a cosmological scale. It is also found that the generator of gravity is contributing mass to particles that have gravitational interaction.

Background： Consuming moderate amounts of lean red meat as part of a balanced diet valuably contributes to intakes of essential nutrients, in this study, we merged phenotypic and genotypic information to characterize the variation in lipid profile and sensory parameters and to represent the diversity among 15 cattle populations. Correlations between fat content, organoleptic characteristics and lipid profiles were also investigated. Methods： A sample of 436 largely unrelated purebred bulls belonging to 15 breeds and reared under comparable management conditions was analyzed. Phenotypic data -including fatness score, fat percentage, individual fatty acids （FA） profiles and sensory panel tests- and genotypic information from 11 polymorphisms was used. Results： The correlation coefficients between muscle total lipid measurements and absolute vs. relative amounts of polyunsaturated FA （PUFA） were in opposite directions. Increasing carcass fat leads to an increasing amount of FAs in triglycerides, but at the same time the relative amount of PUFAs is decreasing, which is in concordance with the negative correlation obtained here between the percentage of PUFA and fat measurements, as well as the weaker correlation between total phospholipids and total lipid muscle content compared with neutral lipids. Concerning organoleptic characteristics, a negative correlation between fiavour scores and the percentage of total PUFA, particularly to n-6 fraction, was found. The correlation between juiciness and texture is higher than with flavour scores. The distribution of SNPs plotted by principal components analysis （PCA） mainly reflects their known trait associations, although influenced by their specific breed allele frequencies. Conclusions： The results presented here help to understand the phenotypic and genotypic background underlying variations in FA composition and sensory parameters between breeds. The wide range of traits and breeds studied, along with the genotypic informa

Numerical Solution of 2-D Diffusion Problems Using Discrete Duality Finite Volume Method on General Boundary Conditions

Journal of Applied Mathematics and Physics 2022年第6期10卷 1968-1997页

作者： hubert Donfack Aubin Kinfack Jeutsa Faculty of Science The University of Bamenda Bamenda Cameroon Higher Technical Teachers’ Training College The University of Buea Kumba Cameroon

In this paper, we present a discrete duality finite volume (DDFV) method for 2-D flow problems in nonhomogeneous anisotropic porous media under diverse boundary conditions. We use the discrete gradient defined in diamond cells to compute the fluxes. We focus on the case of Dirichlet, full Neumann and periodic boundary conditions. Taking into account the periodicity is the main new ingredient with respect to our recent works. We explain the procedures step by step, for numerical solutions. We develop a matlab code for algebraic equations. Numerical tests were provided to confirm our theoretical results.
