《中国稻米》2003,(4):41-42
GB1354-1986《大米》发布实施以来 ,对我国稻米的生产和流通起了重要作用。但随着经济的发展 ,为了更好的对稻米品质进行评判 ,适应我国稻米市场的新发展 ,为按质论价提供依据和促进水稻品种结构调整 ,有必要制订食用粳米的农业行业标准。本标准是在GB1354-1986《大米》的基础上制定的 ,并参照了GB1350-1999《稻谷》、GB/T17891-1999《优质稻谷》及NY20-1986《优质食用稻米》。本标准将技术指标分解为强制性指标和推荐性指标 ,增加了有关稻米品质内涵的指标 ,确立了综合评判的规则。一、范围本标准规定了食用粳米的有关定义、分类、要… 相似文献

The synthesis of 9-(4-vinylbenzyl)-9H-carbazole (VBCz) monomer and surface characterizations of thin film coating of poly(9-(4-vinylbenzyl)-9H-carbazole), P(VBCz) homopolymer on carbon fiber microelectrode (CFME) was performed. Coatings of polymer thin films obtained,
with different initial monomer concentrations, were characterized by cyclic voltammetry, scanning electron microscopy and
Fourier transform infrared reflectance-attenuated total reflection spectroscopy. Different initial monomer concentrations
(1, 3, 5, and 10 mM) were electrodeposited in 0.1 M lithium perchlorate/acetonitrile solution. The characterization of the
thin polymer films was performed on the surface of carbon fiber, and composition of polymeric structure was proposed. Capacitor
behavior of modified CFME was studied by electrochemical impedance spectroscopy. The deposition charge of polymer growth affected
the redox parameters of resulting coated CFME. 相似文献

Background: One of the limitations in the treatment of common diseases such as cancer chemotherapy is development of multidrug resistance (MDR). Polymorphisms could alter the expression level of MDR1 gene, which plays an important role in MDR. In this research, the frequency of C3435T, C1236T, and G2677T/A polymorphisms of MDR1 gene was investigated in a large group of population from Hamadan city to provide a sample data resource. Methods: Peripheral blood (2 ml) was taken, and DNA extraction was carried out. Multiplexed mutagenically separated PCR, which was followed by polyacrylamide gel electrophoresis and silver staining, was applied to detect the mentioned polymorphisms in 935 individuals. Sequencing performed for confirmation of gel electrophoresis resulted in 10 random cases. In total, alleles and genotypes of 933 persons (776 women and 157 men) were determined. Results: The most frequent alleles of the polymorphisms were: 3435T, C1236, and G2677. The most frequent genotypes were: 3435C/T, 1236C/T, and 2677G/A, and their concurrent presence was also found as the most frequent simultaneous genotypes. There was not any meaningful difference among the prevalence of these genotypes in groups of men and women. Conclusion: Our results were close to those of other studies performed in Iran and compared to the other ethnic groups, which showed more similarity to Asian peoples than Europeans. As an aspect of personalized medicine, it could be used by chemotherapists to improve the routine methods of cancer treatment.Key Words: Gene polymorphism, Multi-drug resistance, Neoplasm 相似文献
