Of 21 HCC shown to have 249 codon mutation, 20 exhibited high intranuclear accumulation of p53 protein. p53 protein staining was negative in the surrounding noncancerous hepatic tissue.

启东肝细胞癌中，p53基因发生着249密码子的持续性、纯合型的高频度错义突变，它伴随着p53蛋白在癌细胞核内较普遍的高度积累。

The production of human alpha lactalbumin was 0.64 g/L approximately. The results indicate that the bovine mammary epithelial cell line have the ability of expressing exogenous gene, the 5′ flanking sequence of bovine αS1 casein gene has the effect of regulating gene expression specifically and the vector αS1-LA-psv which was constructed can coexpress alpha lactalbumin and β-galactosidase.

实验结果表明，建立的奶牛乳腺上皮细胞系具有外源基因表达活性，得到的牛αS1-酪蛋白5′调控序列能作为启动子指导外源基因的表达，构建的真核表达载体能在体外培养的牛乳腺上皮细胞中同时表达人α-乳白蛋白和β-半乳糖苷酶。

Whole protein patterns during early stage of gynogenesis were first studiedthrough 2D electrophoresis. 11 specific protein dots were found, among which3(A1 ～A3 )were suggested to be the kind of inverse function factors which suppressgenes activating megagamete division, 8 (Bl～B8)were suggested to be closelyrelated with megagamet division activation.

通过双向电泳技术研究了黄瓜雌核发育早期的特异蛋白质表达，并发现了11个特异多肽点，其中3个(Al～A3)可能是开启分裂基因表达的一类反式作用因子，起抑制该基因表达作用。8个(B1～B8)可能是启动雌配子分裂密切相关的基因表达产物。

They also had the opposite effect from methylated cytosines found in promoter regions.

At ld before anthesis, a biggest vacuole located at the micropyle end of the cell and its nucleus was pushed toward the chalazal end of the cell, which made an evident cellular polarity.

受精后合子中的钙颗粒又明显增多，在核质中分布一些较大的钙颗粒，在珠孔端大液泡中聚集了较多的絮状钙。

To solve the problem numerically, a mollification method is considered. Error estimate between the exact solution and its approximation is given.

作者在文章中提出了一类正则化方法，通过巧妙地选取适当的参数及相应高斯核正则化子来构造逼近解，并给出了逼近解的近似程度估计。

Furthermore, the nucleate flow boiling heat transfer coefficient formula was put forward according to the conclusions of heat soliton.

根据微槽中反应汽泡热通量的热孤子表达式，从理论上获得了以核态沸腾为主的微槽相变传热计算公式。

Abstract］ AIM:To investigate the role of nuclear factor κB in the induction of iNOS gene by TNFα and LPS in endothelial cells and the effect of antioxidant on the induction of iNOS. METHODS:Nitrite was determined based on Griess reaction. iNOS mRNA was analyzed using Northern blot. NFκB in the cell nucleole was detected with electrophoretic mobility shift assay.RESULTS:(1)NO production and iNOS mRNA expression induced by LPS and TNFα was blocked by pyrrolidine dithiocarbamate or N-acetylcysteine.

研究表明内皮细胞激活时iNOS表达的调控主要发生在转录水平。iNOS基因的启动子区域含有多个转录因子的结合位点包括NFκB、AP-1、NF-IL6，Oct-1等［2］，而核因子κB(nuclear factor κB， NFκB)被认为在多种参与炎症反应的蛋白质因子的基因调控中担任重要角色，因而可能是内皮细胞激活的调控中一个重要转录激活因子［2，3］。

Different from the traditional approach of solving GDA by singular value decomposition,the new algorithm utilizes kernel modified Gram-Schmidt orthogonalization algorithm to extract the optimal transformation matrix directly,which can not only effectively hold the most discriminant information in the null space of within-class scatter matrix,but also make the solution more stable in numeric.

与传统用奇异值分解获取目标特征子空间的方式不同，新算法运用核修正格兰-施密特正交化过程直接提取最优投影变换矩阵，不仅有效地地保留了类内散度矩阵最具辨别力的零空间信息，同时使所求解在数值上更稳定。
