为实现葛根的全质化利用,将葛根制成全粉并用于重组米的制备,评价葛根全粉对重组米蒸煮特性、质构特性和微观结构的影响。研究发现,随着葛根全粉添加量的增加重组米的L~*值降低,而ΔE值增加。重组米在葛根全粉添加量为0%时糊化度最低,为69.27%,但随着添加量的增加糊化度无显著性差异(p>0.05);而碘蓝值随着葛根全粉添加量的增加而呈减小的趋势,20%时最低,为15.55。不同葛根全粉添加量下重组米蒸煮吸水率无显著性差异,蒸煮吸水率范围为217.84%~235.17%,高于市售原米,但是低于市售重组米;蒸煮损失率和膨胀率都随着添加量的增加呈先减小后增加趋势。葛根全粉的添加显著增加重组米的黄酮和多酚含量,添加量20%时分别为3.80 mg/g和2.42 mg/g,相对于原米其含量增加2.62倍和3.56倍。与市售重组米和原米相比,添加葛根全粉后的重组米截面呈蜂窝状,有密集的微孔,重组米的硬度、黏性、弹性和咀嚼性增加。

Human ribonucleotide reductase (hRR) catalyzes the reduction of ribonucleotides to their corresponding deoxyribonucleotides,which are the building blocks for DNA replication and repair. The enzyme is composed of two identical large (hRRM1) and two identical small (hRRM2) subunits,p53R2 is a newly identified p53-inducible protein which has～80%sequence homology with *** p53R2 gene contains a p53-binding site in intron *** expression ofp53R2,but not hRRM2,is induced by ultraviolet light,r-irradiation or DNA-damaging agents in a p53-dependent ***,p53 can interact with p53R2 and hRRM2 at the protein level to regulate RR activity in response to genomic *** that fail to make p53R2 are more sensitive to killing by DNA-damaging agents.A study using p53R2 knockout mice showed that impairment of the p53R2-involved DNA repair pathway enhances the frequency of spontaneous mutations and activates p53-dependent apoptotic pathway(s).These findings lead to the hypothesis that there are two pathways in human cells to supply dNTPs for DNA synthesis:one through the activity of hRRM2,involved in normal maintenance of dNTPs for DNA replication during the S phase in a cell cycle-dependent manner,and the other through p53R2,supplying dNTPs for DNA repair in G0/G1 cells in a p53-dependent ***,p53R2 has been shown to possess a crucial role in dNTP supply for mtDNA *** other functions of p53R2,such as facilitates p21 induction of G1 arrest under UV irradiation,are also *** discovery of p53R2 has created much interest in its molecular characteristics and its possible role in tumorigenesis and cancer *** investigations have shown that alterations of p53R2 may have implication in tumor development and *** key role of hRR in DNA synthesis and cell growth control has made it an important target for anticancer therapy,p53R2,functioning in p53-dependent DNA repair pathway,may have the potential to be considered as a

Journal of Systems Science & Complexity 2024年第5期37卷 2207-2239页

作者： shao Wenbing CHEN Falai Department of Mathematics University of Science and Technology of China

Surface/surface intersection is a fundamental problem in Compute Aided Design and Geometric Modeling since it is essential to solid modeling, numerically controlled machining, feature recognition, computer animation, etc. In practical applications, quadric surfaces, which are the most basic type of surfaces, are typically bounded surfaces trimmed by a sequence of planes. In this paper,a robust algorithm is proposed for computing the intersection curve segments of two trimmed quadrics based on the parametric representation of the intersection curves of two quadrics. The proposed algorithm guarantees correct topology and ensures that the approximation errors of the end points of the intersection curve segments are less than a given tolerance. The error control is based on an effective solution to a set of polynomial inequality system using the root isolation technique. Some examples are presented to validate the robustness and effectiveness of the proposed algorithm.
