Recovering context-specific gene network modules from expression data: A brief review
Frontiers of Biology in China - Tập 4 - Trang 414-418 - 2009
Hui Yu, Yuan-Yuan Li
With the popularization of microarray experiments in biomedical laboratories, how to make contextspecific knowledge discovery from expression data becomes a hot topic. While the static “reference networks” for key model organisms are nearly at hand, the endeavors to recover context-specific network modules are still at the beginning. Currently, this is achieved through filtering existing edges of ... hiện toàn bộ
Temporal-spatial variation and the influence factors of precipitation in Sichuan Province, China
Frontiers of Biology in China - Tập 3 - Trang 236-240 - 2008
Ruimin Liu, Zhenyao Shen
Precipitation is a key factor in the water cycle. At the same time, precipitation is the focus of study in meteorology and climatology, ecological environmental assessment, non-point source pollution and so on. Understanding the temporal-spatial variation and the corresponding factors of precipitation has become the object of hydrology and environmentology. Based on the annual precipitation data, ... hiện toàn bộ
Identification of superoxide dismutase isoenzymes in tobacco pollen
Frontiers of Biology in China - Tập 4 - Trang 442-445 - 2009
Jing Wang, Xuequn Liu, Guanghui Yu
We investigated the possible existence of superoxide dismutase (SOD; EC 1.15.1.1) isoenzymes in the pollen of Nicotiana tabacum (Petit Havana SR-1 cultivar). To detect SOD activity, crude extracts from tobacco pollen were subjected to native polyacrylamide gel electrophoresis followed by staining with nitroblue tetrazolium (NBT). The presence of six SOD isoenzymes was detected in tobacco pollen. T... hiện toàn bộ
Spatial variability of soil fertility factors in the Xiangcheng tobacco planting region, China
Frontiers of Biology in China - Tập 4 - Trang 350-357 - 2009
Haisheng Chen, Zili Shen, Guoshun Liu, Zhengxian Tong
It is essential to understand the spatial variability of soil properties in tobacco planting regions, so that the right decision can be made as to how many fertilizer rates are likely to be appropriated for the highquality tobacco production. A total of 159 soil samples were taken from the surface soil (0-20 cm) in the Xiangcheng tobacco planting fields, Henan Province, in April 2002 to examine th... hiện toàn bộ
Home ranges and habitat vegetation characters in breeding season of Narcissus Flycatcher and Yellow-rumped Flycatcher
Frontiers of Biology in China - Tập 2 Số 3 - Trang 345-350 - 2007

The Shanita fauna (Permian foraminifera) from Baoshan area, western Yunnan Province, China
Frontiers of Biology in China - Tập 2 - Trang 114-124 - 2007
Hao Huang, Xiangning Yang, Xiaochi Jin
Studies in the past decade have proven the Shanita fauna to be an excellent marker of the northern peri-Gondwana tectonic blocks. Thus, a study of the Shanita fauna from the Baoshan area in western Yunnan Province, China, could provide pivotal paleontological evidence for the paleogeographic reconstruction of the Baoshan block. We systematically analyzed the composition and the age of the Shanita ... hiện toàn bộ
Alterations of gene expression profiles induced by sulfur dioxide in rat lungs
Frontiers of Biology in China - Tập 2 - Trang 369-378 - 2007
Ziqiang Meng, Guohua Qin, Juli Bai, Jianbiao Zhang, Xin Zhang, Zhenghua Yang
Sulfur dioxide (SO2) is a ubiquitous air pollutant, presents in low concentrations in urban air and in higher concentrations in working environment. Few data are available on the effects of being exposed to this pollutant on the molecular mechanism, although some biochemical changes in lipid metabolism, intermediary metabolism and oxidative stress have been detected. The present investigation aime... hiện toàn bộ
Sequence variability analysis on major histocompatibility complex class II DRB alleles in three felines
Frontiers of Biology in China - Tập 3 - Trang 55-62 - 2008
Qian Wang, Xiaobing Wu, Peng Yan, Shuai Zheng
The variation of the exon 2 of the major histo-compatibility complex (MHC) class II gene DRB locus in three feline species were examined on clouded leopard (Neofelis nebulosa), leopard (Panthera pardus) and Amur tiger (Panthera tigris altaica). A pair of degenerated primers was used to amplify DRB locus covering almost the whole exon 2. Exon 2 encodes the β1 domain which is the most variable fragm... hiện toàn bộ
The spindle assembly checkpoint: perspectives in tumorigenesis and cancer therapy
Frontiers of Biology in China - Tập 6 - Trang 147-155 - 2011
Joana Barbosa, Ana Vanessa Nascimento, Juliana Faria, Patrícia Silva, Hassan Bousbaa
Loss or gain of chromosomes, a condition known as aneuploidy, is a common feature of tumor cells and has therefore been proposed as the driving force for tumorigenesis. Such chromosomal instability can arise during mitosis as a result of mis-segregation of the duplicated sister chromatids to the two daughter cells. In normal cells, missegregation is usually prevented by the spindle assembly checkp... hiện toàn bộ
Characteristics and functions of traditional homegardens: a review
Frontiers of Biology in China - Tập 4 - Trang 151-157 - 2008
Huyin Huai, Alan Hamilton
Traditional agroecosystems play an important role in the conservation of biodiversity and in sustainable development. As a typical type of traditional agroecosystem, traditional homegardens have been receiving increasing attention from scientists, especially ethnobotanists. They are considered as germplasm banks for many crops and other economic plants. They are also a key site for domestication o... hiện toàn bộ
