发生生物学

In recent years, as methods of the molecular phylogeny widely used in the studies of systematics and phylogeny of Nymphalidae, the basic phylogenetic patterns of them have been clarified. However, up to the present, these studies, especially about the taxa distributed in China is rather scarce.

近年来，由于分子生物学在蛱蝶科系统分类中的广泛应用，蛱蝶科各主要类群间系统发生关系的格局逐步清晰，但国内蛱蝶科的分子系统学研究还十分匮乏。

In this paper, the biology and ecology of Olethreutes leucaspis Meyrick were studied more comprehensively.

主要研究结果如下： 1三角新小卷蛾生物学：三角新小卷蛾在大棚条件下一年发生10代，世代重叠。

Now, the quantity of Olethreutes leucaspis Meyrick become more than 85% of all the leaf rollers which are harmful to litchi and longan, It have already become the advantage population of leaf rollers which has endangered litchies , longan.

本课题对三角新小卷蛾的生物学、生态学进行较为全面的研究，观察其生活习性，掌握其发生为害规律，为有效的防治该虫提供科学依据的理论基础。

As a sexual reproductive organ, ovules have received much attention by botanists. Since the nineteenth century, the morphology, structure, ontogenesis, origin and molecular biology of angiosperm ovules have been studied in detail.

胚珠作为被子植物的有性生殖器官一直为植物学家所关注。19世纪以来，人们从形态结构、发生发育、起源及分子生物学等方面对胚珠进行了大量的研究。

These data shows the expression of p53,p27 and mdm2 are related to the ontogenesis and progression of GIST. p53,p27 and mdm2 may be prognostic indicators in GIST.

p53、p27和mdm2蛋白表达与GIST的发生、发展有关，检测p53、p27及mdm2表达可以作为GIST生物学行为评价的有效指标。

Anxiety is one of the physiopsychic diseases with high incidence rate.

焦虑症是目前发病率较高的身心疾病之一，现代医学认为本病的发生与个体生物学特征和社会心理因素有关。

As results, TEM showed characteristic ultrastructure morphology of apoptosis cell with chromatin marginal condense, nucleus pycnosis, mitochondrion vacuoles and cell shrinkage in IR injury group and no apoptosis cells in control group. Increased TUNEL-positive cell and typical DNA laddering were found and cells apoptotic rate were approximately 20% by flow cytometry assay in experimental groups.

值得探讨。本试验通过流式细胞仪、生物电镜、TUNEL法、RT-PCR以及DNA电泳等试验方法研究了带血供同种异体骨移植过程的细胞凋亡现象，并检测了Fas、FasL、Caspase-1、Caspase-3、Bcl-2等凋亡相关基因在IR损伤时的表达及变化情况，初步探讨了骨移植时IR损伤中细胞凋亡的发生机制及其在IR损伤中的生物学意义，希望为今后更深入的研究打下一定基础。

This study demonstrates the integral function of SA, particularly streptococcal DNA, in the pathogenesis of psoriasis.

该研究通过揭示链球菌抗原的生物学功能，发现non-NASA相比SA可显著降低银屑病患者PBMC增殖和T细胞活化，提示链球菌DNA可辅助活化致病性T细胞，诱导银屑病的发生与发展。

E. the ratio of uncoupler concentration to sludge concentration was a better parameter to choose uncoupler.

分子生物学手段检测表明污泥中的细菌种群结构也发生了改变。

Some genetic bases underlye the plant somaclonal variation, which can be integratively determined and identified at morphological, cytological, biochemical and molecular biological levels.

植物体细胞无性系变异的发生有其遗传学基础，可从形态学、细胞学、生物化学和分子生物学等多个方面对其进行综合检测和鉴定。
