Source and Inheritance of the Within Cultivar Residual Variation Detected in an indica Variety IR64

引用

Rice science 2007年第1期14卷 21-26页

作者： WU Jian-li SHI yong-feng CHEN Jie Casiana Vera cruz ZHUANG Jie-yun Hei LEUNG ZHENG Kang-le Chinese National Center for Rice Improvement/State Key Laboratory of Rice Biology China National Rice Research Institute Hangzhou 310006 China Plant Breeding Genetics and Biotechnology Division International Rice Research Institute DAPO Box 7777 Metro Manila Philippines

The phenotypically uniform indica variety IR64 was chosen for study of the source and inheritance of within cultivar residual variation using a set of SSR markers. Residual heterogeneity in IR64 was identified on the short arm of chromosome 2 involving at least 5 SSR loci spanning nearly 30 cM. The SSR variations originated from the parental lines of IR64 （IR5657-33-2 / IR2061-465-1-5-5） and were segregating in the selfed bulk seed stock in a Mendelian manner for more than 20 years. This study verified that the within cultivar variations of SSR in a morphologically uniform variety IR64 of a selfing crop came from its parental lines, which has immediate and commercial applications including test of hybrid seed purity, varietal fingerprinting, and curation and propagation of germplasm collections.

CdSe Quantum Dot-Sensitized Au/TiO2 Hybrid Mesoporous Films and Their Enhanced Photoelectrochemical Performance

引用

Nano Research 2011年第3期4卷 249-258页

作者： liping liu Gongming Wang yat li yadong li Jin Z. Zhang Department of Chemistry Tsinghua University Beijing 100084 China Department of Chemistry and Biochemistry University of California Santa Cruz CA 95064 USA

Novel CdSe quantum dot （QD）-sensitized Au/TiO2 hybrid mesoporous films have been designed, fabricated, and evaluated for photoelectrochemical （PEC） applications. The Au/TiO2 hybrid structures were made by assembly of Au and TiO2 nanoparticles （NPs）. A chemical bath deposition method was applied to deposit CdSe QDs on TiO2 NP films with and without Au NPs embedded. We observed significant enhancements in photocurrent for the film with Au NPs, in the entire spectral region we studied （350-600 nm）. Incident-photon-to-current efficiency （IPCE） data revealed an average enhancement of 50%, and the enhancement was more significant at short wavelength. This substantially improved PEC performance is tentatively attributed to the increased light absorption of CdSe QDs due to light scattering by Au NPs. Interestingly, without QD sensitization, the Au NPs quenched the photocurrent of TiO2 films, due to the dominance of electron trapping over light scattering by Au NPs. The results suggest that metal NPs are potentially useful for improving the photoresponse in PEC cells and possibly in other devices such as solar cells based on QD-sensitized metal oxide nanostructured films. This work demonstrates that metal NPs can serve as light scattering centers, besides functioning as photo-sensitizers and electron traps. The function of metal NPs in a particular nanocomposite film is strongly dependent on their structure and morphology.

Glucocorticoid receptor expression in neonatal rat cortex following recurrent seizures The role in developing brain injury

引用

Neural Regeneration Research 2010年第2期5卷 146-149页

作者： Tao Bo Lu yi Tuanmei Wang Jian li Xingfang li Dingan Mao Department of Pediatrics Second Xiangya Hospital Central South University Changsha 410011 Hunan Province China

BACKGROUND： Studies have explored changes in neonatal rat glucocorticoid receptor （GR） expression changes following mature brain injury. OBJECTIVE： To investigate the temporal and special changes of GR during brain development in rats with recurrent seizures. DESIGN, TIME AND SE＇n＇ING： A randomized, controlled animal experiment was performed at the Department of Pediatrics, Second Xiangya Hospital of Central South University, from February 2008 to March 2009. MATERIALS： Rabbit anti-rat GR monoclonal antibody was purchased from Santa cruz Biotechnology, USA; goat anti-rabbit IgG was purchased from Zhongshan Goldenbridge Biotechnology, China. METHODS： A total of 48 Sprague-Dawley rats, 7 days old, were randomly assigned to control and seizure groups, with 24 animals in each group. Seizures were induced by inhalant flurothyl. MAIN OUTCOME MEASURES： Changes in GR protein expression in the rat cerebral cortex were detected by Western blotting analysis and immunohistochemistry. RESULTS： GR expression in the cerebral cortex of control rats significantly increased with aging （P 〈 0.05）, and varied in the frontal lobe, temporal lobe, and parietal lobe. GR was predominantly expressed in the cytoplasm early and rapidly increased in the nuclei. GR protein expression in the cerebral cortex after seizure was lower in the cytoplasm at 15 days and in nuclear protein at 19 days. CONCLUSION： GR expression displayed temporal and spatial changes in brain development. Recurrent seizures in neonatal rats cause abnormal GR expression and might play an important role in developing brain injury.

A special kind of local structure in the CMB intensity maps: duel peak structure

引用

Chinese Journal of Astronomy and Astrophysics 2009年第3期9卷 302-306页

作者： Hao liu Ti-Pei li Key Laboratory of Particle Astrophysics Institute of High Energy Physics Chinese Academy of Sciences Beijing 100049 China Graduate School of Chinese Academy of Sciences Beijing 100039 China Department of Physics ＆ Center for Astrophysics Tsinghua University Beijing 100084 China Department of Engineering Physics ＆ Center for Astrophysics Tsinghua University Beijing100084 China

We study the local structure of Cosmic Microwave Background （CMB） temperature maps released by the Wilkinson Microwave Anisotropy Probe （WMAP） team, and find a new kind of structure, which can be described as follows： a peak （or valley） of average temperature is often followed by a peak of temperature fluctuation that is 4° away. This structure is important for the following reasons： both the well known cold spot detected by cruz et al. and the hot spot detected by Vielva et al. with the same technology （the third spot in their article） have such structure; more spots that are similar to them can be found on CMB maps and they also tend to be significant cold/hot spots; if we change the 4° characteristic into an artificial one, such as 3° or 5°, there will be less ＂similar spots＂, and the temperature peaks or valleys will be less significant. The presented ＂sim- ilar spots＂ have passed a strict consistency test which requires them to be significant on at least three different CMB temperature maps. We hope that this article could arouse some interest in the relationship of average temperature with temperature fluctuation in local areas; meanwhile, we are also trying to find an explanation for it which might be important to CMB observation and theory.
