Soil degradation, including rocky desertification,of the karst regions in China is severe. Karst landscapes are especially sensitive to soil degradation as carbonate rocks are nutrient-poor and easily eroded. Understanding the balance between soil formation and soil erosion is critical for long-term soil sustainability, yet little is known about the initial soil forming processes on karst terrain. Herein we examine the initial weathering processes of several types of carbonate bedrock containing varying amounts of non-carbonate minerals in the SPECTRA Critical Zone Observatory, Guizhou Province, Southwest China. we compared the weathering mechanisms of the bedrock to the mass transfer of mineral nutrients in a soil profile developed on these rocks and found that soil formation and nutrient contents are strongly dependent upon the weathering of interbedded layers of more silicate-rich bedrock(marls). Atmospheric inputs from dust were also detected.

we expect organisms to have evolved mechanisms to gather and use the information available within their environments, to steer resource investment decisions toward the traits that will give the greatest fitness returns. Pheromones are social signals, a common purpose of which is to act as indicators of mate presence. Consequently, pheromones have the potential to act as signals to increase or maintain reproductive investment over that of competing life-history traits. In the cockroach, Nauphoeta cinerea （oliver）, females pay costs of maintaining investment in reproduction when there are no males, and males produce pheromones that are known to effect female reproductive outcomes. whether the pheromones have an influence on resource physiology is unknown. we subjected newly eclosed females to either a synthetic blend of male pheromones or control. we dissected females at 7, 12, 17 or 22 days. we measured apoptosis levels and size of all oocytes within the vitellerium, and measured dry fat body mass. Synthetic male pheromone blend did not have an effect on any measure of female reproductive or somatic resource physiology. Although negative results are always problematic, the success of the synthetic pheromone method in the past suggests that females may be insensitive to male pheromones in the pre-oviposition period, and may rely on mating stimulus rather than pheromone as the cue for oocyte maintenance and growth. Previous studies reporting effects of male pheromones on female reproduction suggest that the period of pheromone sensitivity may be between mating and birth.

Purpose This cross-sectional study investigated dynamic force-time variables and vaulting performance in young female gymnasts of different maturity *** 120 gymnasts aged 5-14 years were sub-divided into maturity groupings using percent of predicted adult height(%PAH)*** performed three jumping protocols,the squat jump(SJ),countermovement jump(CMJ)and drop jump(DJ),before completing straight jump vaults that were recorded using two-dimensional *** Jumping performance improved with biological maturity evidenced by the most mature gymnasts’producing sig-nificantly more absolute force(P0.78),impulse(P0.75)and power(P0.91)than the least mature group,resulting in the greater jump heights(P0.70).while,no significant differences were observed in relative peak force across multiple tests,measures of relative peak power did significantly increase with *** upon regression analyses,maturation was found to influence vertical take-off velocity during vaulting,explaining 41%of the variance in each jumping *** all tests,the DJ was found to have the highest predictive ability of vaulting vertical take-off velocity,explaining 55%of the total *** Biological maturation impacts jump height and underpinning mechanical variables in young female *** vertical take-off velocity appears to be influenced by maturation and various dynamic force-time variables,par-ticularly those during DJ,which had the highest explained total variance.

The last decade has seen a steady proliferation in the use of tissue-engineered cell culture systems（Deforest and Anseth,2012）,and these have been put to good use for studying neural axon growth and guidance（Li and Hoffman-Kim,2008;Roy et al.,2013）.These systems have been designed to more closely mimic the natural microenvironment of the developing or repairing nervous system and to enable spatiotemporal control over certain aspects of the microenvironment.

目的:研究榅桲总黄酮对自发性高血压大鼠血压和血管内皮功能的影响。方法:自发性高血压大鼠分为模型组,卡托普利组(25mg·kg^(-1)·d^(-1)),杜仲平压片组(30mg·kg^(-1)·d^(-1)),榅桲总黄酮低、中、高剂量组(40、80、160mg·kg^(-1)·d^(-1)),wKY大鼠作正常对照。灌胃给药16周,每2周测定血压1次,末次给药后分别测定血清内皮素-1(ET-1)、一氧化氮(NO)、内皮型一氧化氮合酶(e NOS)、超氧化物歧化酶(SOD)、丙二醛(MDA)及降钙素基因相关肽(CGRP)的含量,评价榅桲总黄酮对自发性高血压大鼠血压和血管内皮功能的影响。结果:与模型组比较,榅桲总黄酮各剂量组大鼠收缩压和舒张压均呈降低趋势,ET-1和MDA水平降低而NO、e NOS、SOD及CGRP水平均有不同程度升高(P<0.01,P<0.05)。结论:榅桲总黄酮可降低自发性高血压大鼠血压,作用机制可能与抑制血管内皮功能障碍,调节血管舒缩因子释放有关。
