Possible Application of the Medicinal Plant Hyoscyamus albus in Phytoremediation: Excess Copper Compensates for Iron Deficiency, Depending on the Light Conditions

Seedlings of the medicinal plant Hyoscyamus albus were supplied with an excess of Cu to examine the possible application in phytoremediation. The seedlings were cultured in B5 medium supplied with basal 0.1 μM Cu and 200 μM Cu under various light conditions: short day (SD);long day (LD);and continuous light (CL). In addition, the effect of supplying 200 μM Cu under Fe deficiency was determined, in order to elucidate the interaction between Cu and Fe. Interestingly, Fe-deficiency symptoms that developed in plants grown with basic levels of Cu under LD almost disappeared when excess Cu was supplied. Plant growth mainly depended on the photo irradiation period (SD < LD^CL);and 200 μM Cu did not inhibit growth at all when Fe was available, whereas in the absence of Fe, CL caused damage to growth. Analysis of the Cu and Fe contents of the plants revealed that Cu was distributed equally in both the aerial parts and roots, whereas most of the Fe was found in the roots;under Fe deficiency, Cu accumulation in the roots apparently increased. Cu was mainly distributed in the soluble fraction, which included vacuoles and the cell-wall fraction. These results provide evidence indicating that H. albus seedlings are tolerant of Cu present in excess. Furthermore, excess Cu was able to compensate for Fe deficiency, depending on the light conditions. Continuous light inhibited this effect, probably as a result of the induction of Mn deficiency. The possible applications of this newly discovered cuprophyte are discussed.

Laser–plasma interaction and hot electrons have been characterized in detail in laser irradiation conditions relevant for direct-drive inertial confinement *** experiment was carried out at the Gekko XII laser facility in multibeam planar target geometry at an intensity of approximately 3×10^(15)W/cm^(2).Experimental data suggest that high-energy electrons,with temperatures of 20–50 keV and conversion efficiencies ofη<1%,were mainly produced by the damping of electron plasma waves driven by two-plasmon decay(TPD).Stimulated Raman scattering(SRS)is observed in a near-threshold growth regime,producing a reflectivity of approximately 0.01%,and is well described by an analytical model accounting for the convective growth in independent *** experiment reveals that both TPD and SRS are collectively driven by multiple beams,resulting in a more vigorous growth than that driven by single-beam laser intensity.

＜正＞The energy and water cycle in the Tibetan Plateau is one of the most important features of the climate in Asia. Due to the effects of the atmospheric heating processes controlled by the variations of water storage as soil moisture, snow, and ice, the Tibetan Plateau plays an important role in the water cycle variations in Asia. To enhance predictability based on improved understanding of hydrological processes and its sustained monitoring capability in the Tibetan Pla（?）eau is a key contribution to mitigation of water-related damages and sustainable human development in Asia.

数值模式的可预报性及不确定性目前主要是通过模式比较计划来分析的。这些比较要么侧重于模式的一个方面（e.g. GSWP: global soil wetness project）,要么侧重于单个流域（e.g. PILPS: Project for Inter-comparison of Land-surface Parameterization Schemes）,要么侧重于全球尺度但尚需与观测作进一步比较（e.g. AMIP: Atmospheric Model Inter-comparison Project）。为研究全球水热循环,全球协调加强观测期项目（CEOP: Coordinated Enhanced Observing Period）将收集2001年7月至2004年10月期间36个GEWEX-CSE的参考站（reference site）资料,10个数值模式中心的全球模拟或再分析资料,以及正在运行的众多气象卫星的数据。到目前为止,CEOP已经收集了2001年7月至2001年9月（EOP1）的部分资料。这些资料包括16个参考站资料,一个数值模式中心的全球模拟（NASA/GEOS: Goddard Earth Observing system）和一个数值模式中心的全球陆面同化数据（NASA/GLDAS: Global land data assimilation system）,以及五颗气象卫星的数据（DMSP SSM/1, NOAA AVHRR, TERRA MODIS, GMS SVISSR, TRMM PR, TMI）。通过模式输出与野外观测的比较,不同模式输出的比较,以及模式输出与卫星反演资料的比较,CEOP提供了一个独有的平台,用于分析模式的可预报性及不确定性。本文对CEOP-EOP1的数据作了十天平均,然后对数值模式的可预报性及不确定性作了初步分析。

Influence of Sex Differences on Temporal Sequence of Sensations after Ingesting Fruit-Flavored Tea—A Preliminary Study

引用

Food and Nutrition Sciences 2018年第6期9卷 676-682页

作者： Eimi Sato Emi tamagawa Kumi Naito Mao Nirasawa Ichiro Ashida Satomi Miyaoka Yozo Miyaoka Department of Health and Nutrition Niigata University of Health and Welfare Niigata Japan Department of Mental Health Science Graduate School of Rehabilitation Niigata University of Rehabilitation Murakami Japan

The goal of this preliminary study was to examine the effect of participants’ sexes on the temporal sequence of dominant sensations elicited by fruit-flavored teas. Twelve healthy young adults were assigned to male (n = 6) and female (n = 6) groups. Both groups were evaluated for four sensations using four fruit-flavored teas with 0.05 M sucrose using the temporal dominance of sensations (TDS) method. Only two sensations, sweetness and fruitiness, were consistently reported in the two groups. The male group first reported fruitiness and then sweetness as the dominant sensation following ingestion of the samples. Conversely, the female group reported these two dominant sensations in the reverse order. Significant dominant durations between the two sensations largely varied among the samples in both groups. These results suggest that there are sex-based differences in the temporal sequence of dominant sensations elicited by fruit-flavored teas as evaluated by the TDS method.
