非细胞的

Some useful notations and definitions are give in this chapter.In Chapter 2,a class of discrete-time model of two-cell cellular neural networks with symmetric temptate are investigated. We obtain some results about the stability,asymptotic stability,the existence and attractability of 2-periodic solutions.

第三章讨论了反馈矩阵为非对称矩阵的二元离散细胞神经网络模型的稳定性与渐近稳定性、周期解的存在吸引性，除了得到系统稳定和存在2-周期解的相关结果外，还得到了系统在原点出现类似于Hopf分支的局部分支以及多个吸引4k-周期解的共同存在性。

There was no significant difference in epithelial destruction, intra-luminal obstruction and BO formation between allografts from HO-1 transgenic pigs or non-transgenic pigs. However, in day 28 and 56 allografts, we did see some of the grafts still showed bronchiole structure with normal epithelial cells which hasn'tbeen found before.

使用HO-1 基因猪的异体移植肺块，在气管表皮破坏、气管内径阻塞、及阻塞性细支气管炎形成的程度，与使用非基因猪并无显著差异，惟在第28 天及56 天的肺块中，有部份的异体移植肺块中可见正常的支气管型态及表皮细胞。

METHODS: The immunocytochemistry method was used to as say the expression of HnRNP A2/B1 in fiberobronchoscopic aspirates of lung cancer confirmed by histopathology and/or cytopathology and of benign lung diseases.

利用免疫细胞化学的方法检测经病理学或细胞学确诊的肺癌患者和非肺癌患者的纤支镜抽吸物中HnRNP A2/B1的表达情况，并分析其表达水平的差异性。

The genome of infectious hepatitis B virus is a partially double stranded circular DNA, and that of replicative HBV is a covalently closed circular supercoiled DNA. The patients with chronic HBV infection manifest from non-active virus carrier state to severe active hepatitis, and 15%~25% of which will evolve decompensate cirrhosis and hepatocellular carcinoma.

感染型的乙型肝炎病毒基因组为部分双链环状DNA，复制型的HBV基因组共价闭合环状DNA慢性HBV感染的进展过程多变，从非活动性病毒携带到严重的活动性肝炎；其中约15%~25%的病人最终导致失代偿性肝硬化、肝细胞癌。

Some researchers have argued that so-called "non-thermal effects" could be reinterpreted as a normal cellular response to an increase in temperature.

一些研究者认为，那些所谓的&非热效应&，可以重新定义为在升高的温度中的正常的细胞反应。

In allusion to the above-mentioned problems, considering the self-adaptive regulative ability of the visual system to natural perceptive information and the feedback between visual cortexes, a bidirectional NNSC model is proposed, which is based on the robust principal component analysis and the priors of receptive fields of simple cells in V1. And using the (Polak-Ribiere-Polyak) PRP conjugate gradient descent algorithm, the minimum optimization problem of the objective function can be realized.

针对上述问题，考虑视觉系统对外界感知信息的自适应调整机制和视皮层之间的反馈连接，本文提出了一种基于稳健 PCA 和 V1区简单细胞感受野先验知识的反馈非负稀疏编码模型，并且使用 Polak-Ribiere-Polyak共轭梯度下降优化算法实现了目标函数的最小化问题。

In the present study, it has been proved that advanced glycation end products, which formated by nonenzymatic glycosylation in a long-term high blood glucose, play a important role in the loss of pericytes and development of diabetic retinopathy.

近年来的研究认为，慢性高血糖引起蛋白质非酶糖化所产生的糖基化终产物（adavaced glycation end products，AGEs），在周细胞衰亡、糖网病发生的过程中起着非常重要的作用。

objective this study was designed to investigate the chemotherapy effect and toxicity of co-chemotherapy with megadose tamoxifen in estrogen receptor positive human non-small cell lung carcinoma.

目的 进行大剂量的三苯氧胺 160 mg联合化疗对雌激素受体阳性的非小细胞肺癌患者的近期疗效分析和毒副作用的观察。

We found that neither the fusioned nor the non-fusioned forms of Hu-P68 cDNA open reading frame could express efficiently in the E. coli cells; in different prokaryotic expression vectors and under various promotors resulted in no distinctive variations. Deletion of 5'UTR by synthesis adaptors, deletion of 3'UTR or signal peptide sequence by PCR gained no gross improvement. Only the truncated API-I proteins were observed to be highly expressed when the 3'ORF fragment of the Hu-P68 cDNA was fusioned at the 3'end of PAI-I gene.

结果发现无论是以融合形式存在，还是以非融合形式存在，人的P68 cDNA基因在E.coli细胞中都未能获得高效表达：在不同表达载体中，不同启动子对P68 cDNA基因的表达没有显著差异；利用合成Adapter的方法删除5'UTR，及利用PCR技术删除3'UTR和信号肽序列对表达没有明显改善；分别表达被分割的P68 cDNA5'端编码区、中央编码区和3'端编码区均未见有明显表达；当P68 3'端编码区与高效表达蛋白PAI-Ⅰ基因3'末端融合时，仅见有PAI-Ⅰ以截断形式高效表达出来。

Objective To study the localization and resection of minute space-occupying lesions in the liver with a diameter less than 2 cm.

甲胎蛋白和B超联合检查在肝癌高危人群的检查和随访，使直径≤ 2cm微小肝癌的检出率和切除率明显提高，同时也使一些非肝细胞癌的实质性微小占位病变的检出逐年增加〔1〕。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
