The previously unknown male of Conocephalus (Anisoptera) yunnanensis Shi et Feng, 2009 is described for the first time. female this species redescribed. photographs habitus and characteristic taxonomic features both sexes are also provided.

A new flavonoid, (2R,3R)-3,7,4'-trihydroxy-3',5'-dimethoxyflavanone, named sophorayunnanol (1), together with eight known polyphenols (2-9), were isolated from the roots of Sophora yunnanensis C.Y.MA (Leguminosae). The structure including absolute stereochemistry of 1 was determined by spectroscopic (high resolution (HR)-MS, 1D- and 2D-NMR, and circular dichroism (CD)) methods. The inhibitory a...

Mangroves are ecosystems located in the transition zone between land and sea that serve as a potential source of biotechnological resources. Brazil's extensive coast contains one of the largest mangrove forests in the world (encompassing an area of 25,000km2 along all the coast). Endophytic bacteria were isolated from the following three plant species: Rhizophora mangle, Laguncularia racemosa a...

Ultraviolet (UV)-irradiation causes an overproduction of matrix metalloproteinases (MMPs) and collagen (COL) degradation causing skin sunburn, inflammation, or photoaging in human. In this study, we prepared callus from Tiarella polyphylla D. Don ( T. polyphylla) stem its phytochemical profiles were analyzed using HPLC-MWD. The effects extract evaluated against on UVB-induced damage human fores...

Three new species belonging to two genera of the aleocharine tribe Termitopaediini Seevers, viz., Dioxeuta rara Song & Li, sp. n., D. yunnanensis Song & Li, sp. n., and Termitopulex sinensis Song & Li, sp. n. from Baihualing Natural Reserve (Southwest China: Yunnan) are described and illustrated. This is the first record of Termitopulex Fauvel, 1899 from China.

This thesis deals with statistical questions raised by the analysis of highdimensional genomic data for cancer research. In the first part, we study asymptotic properties of multiple testing procedures that aim at controlling the False Discovery Rate (FDR), that is, the expected False Discovery Proportion (FDP) among rejected hypotheses. We develop a versatile formalism to calculate the asympto...
