次生代谢产物异黄酮是一类主要在豆科植物中合成的多酚类物质。异黄酮不仅利于豆科植物应答生物和非生物胁迫、诱导根瘤形成等，而且对人体具有重要的保健和药用价值，比如预防和治疗癌症、心脑血管疾病和骨质疏松等。大豆是工业化生产异黄酮的重要来源，主要含有12种异黄酮物质及其衍生物。根据其化学结构的差异，可将其分为游离型苷元（aglycone）和结合型糖苷（glycoside）两大类，其中结合型糖苷占异黄酮总量...

Sandbars are of vital ecological and environmental significance, which however, have been intensively influenced by human activities. Morphodynamic processes of sandbars along the Yichang-Chenglingji ...
Modulation of Nhlh2 expression by energy availability leads to downstream effects on body weight regulation
The hypothalamus transcription factors nerve energy hormone neurons arcuate nucleus neurons
2014/12/11
Mice with a deletion of the hypothalamic basic helix-loop-helix transcription factor Nhlh2 (N2KO) display adult onset obesity, implicating Nhlh2 in the neuronal circuits regulating energy availability...
EUFODOS: European Forest Downstream Services – Improved Information on Forest Structure and Damage
LiDAR airborne laser-scanning EUFODOS forest parameters protective forest tree height tree tops
2014/4/24
Forests play a key role in the European economy and environment. This role incorporates ecological functions which can be affected by the occurrence of insect infestations, forest fire, heavy snowfall...
Width dependent collisionless electron dynamics in the static fields of the shock ramp,1,Single particle behavior and implications for downstream distribution
Width dependent collisionless electron dynamics static fields shock ramp
2009/11/13
We study the collisionless dynamics of electrons in the shock ramp using the numerical trajectory analysis in the model electric and magnetic fields of the shock. Even with very modest assumptions abo...
Downstream and soaring interfaces and vortices in 2-D stratified wakes and their impact on transport of contaminants
Downstream soaring interfaces vortices 2-D stratified wakes transport of contaminants
2009/11/9
The flow of continuously stratified fluids past obstacles was studied analytically, numerically, and experimentally. The obstacles discussed here include a flat strip, aligned with the flow, inclined ...
A Simple Approximation of the Hydrograph Downstream of a Flooded Area
Simple Approximation Hydrograph Downstream Flooded Area
2009/10/27
A simple model for estimating the hydrograph at the outlet of a reach crossing
a flood-prone area is investigated. The first part of the model involves routing
of the inflow hydrograph through an id...
Anisotropic unstable ion distribution functions downstream of the solar wind termination shock
ion plasma state solar wind
2009/5/27
In this paper we demonstrate that solar wind ions, passing over the quasiperpendicular portion of the solar wind MHD termination shock, unavoidably develop strongly pronounced pitchangle anisotropies....
An Oceanic Wake in the Equatorial Undercurrent Downstream from the Galapagos Archipelago
Oceanic Wake Galapagos Archipelago Equatorial Undercurrent Downstream
2009/4/2
In the Pacific Equatorial Undercurrent downstream (east) from the Galapagos archipelago, an unusual meander pattern was observed in the spring of 1967. Two separate hypotheses present themselves as ex...
