Differences exist in land use/cover pattern and its change between the P. R. China and the USA. In order to describe those differences, land use changes in representative regions were quantitatively analyzed and compared. Xiamen City, Changzhutan region and Liupan Mountains regions were selected to represent three different hydrogeomorphic areas of eastern, central, and western China, respectively, while the Goodwin Creek Experimental Watershed (GCEW) located in the north-central part of Mississippi in the bluff hills j.st east of the Mississippi River floodplain was chosen in the USA. By integrating historical Landsat TM imagery and geographical information system data, the spatiotemporal land use dynamics and conversion of land use in China and the USA between 1980 and 2010 were explored and compared. Results indicated an urban sprawl in eastern and central China, which encroached upon large amount of cropland, forest land and grassland. On the other hand, western China reclaimed cropland from grassland, forest land, which led to severe soil erosion between 1990 and 2000. Goodwin Creek Watershed of the USA converted 73.3% of the lost cropland into forest land, pasture and idle land, which accounted for about 90% in 2010. Further, counter-urbanization occurs in the GCEW due to favorable eco-environment for living. Compared with the land dynamic degree of the GCEW, eastern China is greater than it;western China is smaller than it while central China is almost equal to it. And the land use intensity index of GCEW is smaller than that of China all these years. Eastern China advocated ecological civilization in 2007 to meet the serious challenges of sustainable development. Western China started the Return of Land from Farming to Forestry and Grassland Proj.ct in 2000. The Changzhutan region in central China is served as the resource-saving and environment-friendly community in 2007, which will be favorable for the sustainable land utilization and protection of ecology

Disruption of Drug Effects (Dopamine, Nicotine, Pilocarpine, κ-Opioid) in Planarians by UV Light

引用

Pharmacology & Pharmacy 2012年第3期3卷 358-363页

作者： Robert B. Raffa Christopher S. Tallarida Aruj.Choudhry Nadia Sanni-Adam Sean McGonigle Michael Baron Zhuo L. Chen Scott M. Rawls ronald j.

Based on previous work, it has been hypothesized that the energetics of ultraviolet (UV) light disrupts effects induced by receptor-binding ligands. If this hypothesis is true, then UV light should (i) disrupt a broad variety of endpoints and (ii) disrupt effects produced by ligands that bind to diverse receptor types. This was tested directly in the present study by using ligands selective for four different receptors (one ionotropic, three metabotropic) and three different behavioral endpoints. The selective dopamine D2 receptor antagonist (–)sulpiride (0.1 uM) dose-relatedly decreased spontaneous locomotor velocity, the selective nicotinic acetylcholine receptor agonist nicotine (1, 3, 5 mM) and the selective muscarinic acetylcholine receptor agonist pilocarpine (20, 30, 50 mM) induced seizure-like activity, and the selective-opioid receptor agonist U-50,488H (10 uM) produced physical dependence (manifested as abstinence-induced withdrawal) in planarian models. Each of these diverse ligand and receptor-mediated effects were attenuated by UV light (254 nm = 7.83 × 10–19 j.= 4.89 eV). These findings provide further evidence that UV light disrupts ligand-receptor mediated interactions and that UV light might provide a useful tool for examining drug-receptor interactions.

We have taken a combination of genetic, biochemical, and molecular approaches to understand the brassinosteroid (BR) signal transduction pathways. Brassinosteroids play important roles in multiple plant developmental processes, particularly those related to light. BR biosynthetic and insensitive mutants such as det2 and bril, respectively, show many characteristics of light-grown plants when grown in the dark and are dwarfs when grown under light. Molecular genetic studies during the past few years have led to the identification of several genes involved in BR biosynthesis and only one gene, BRI1, required for BR responsiveness. BRI1 is a membrane bound receptor kinase with a leucine-rich-repeat (LRR) extracellular domain, a transmembrane domain, and a cytoplasmic kinase domain with serine/threonine specificity. A popular model to be tested is that BRI1 is the BR receptor.

Spontaneous Baroreflex Sensitivity in Normotensive African-American Men

Purpose: African-American men (AAM) have a greater risk of hypertension (HTN) than Caucasian men (CM). To reduce this risk, determining the differences in mechanisms involved in HTN and understanding the relationship between these mechanisms and factors affecting blood pressure (BP) in AAM and CM is necessary. One such mechanism is spontaneous baroreflex sensitivity (sBRS) and two factors are cardiorespiratory fitness (CRF) and arterial stiffness (AS). The aims of this study were to determine, firstly, whether there are differences in sBRS between young, normotensive AAM and CM, and secondly, to determine if CRF and AS are significant predictors of sBRS in young, normotensive AAM and CM. Methods: Twenty-three normotensive AAM and 36 CM were recruited from Southern Connecticut State University. Measures included anthropometric, sBRS (alpha-index), and CRF (maximal oxygen consumption [VO2max]), as well as AS (carotid-femoral pulse wave velocity [Cf-PWV]). Independent t-tests were used to determine differences between groups and multiple regression analysis was used to determine how much of the variation in sBRS was explained by CRF and AS. Results: The sBRS was significantly lower in AAM (10.3 ± 3.8 ms/mmHg) vs. CM (13.3 ± 5.7 ms/ mmHg), P = 0.03. CRF and AS were not significant predictors of sBRS in AAM (P = 0.25) and CM (P = 0.30). There was no relationship between, sBRS, CRF and AS;CRF was significantly reduced in AAM vs. CM (45.1 ± 6.3 vs. 52.1 ± 7.5 mL·kg?1·min?1, P ≤ 0.001). Conclusions: Young normotensive AAM demonstrated significantly lower sBRS vs. CM, irrespective of having fair CRF and normal BP. CRF and AS are not significant predictors of sBRS in young, normotensive AAM and CM. The attenuation in sBRS in AAM did not result in AAM having higher BP versus CM. This finding underscores the need for more detailed examination of the role of sBRS in the etiology of HTN in AAM.

本文重点考察了专家知识与案件审理模式之间的关系。总体而言,案件审理是一种教育性活动,其间,事实认定者应能够理解、处理和思考证据,并得出理性的结论。这一过程反映了审理中准确事实认定的根本重要性,若没有准确的事实认定,权利和义务便是空谈。专家证据通常涉及一种遵从性而非教育性的诉讼程序模式,从这一点上来说其有悖于常规的审判理想状态。本文讨论了这一发展过程、其形成原因及其后果。若要实现审判的理想状态,那么替代性措施(即所有证据应以教育性模式呈现)则更为优越。如果证据无法以此种方式(教育性模式)呈现,那么在审理过程中通过证据所展现的待证事项便无法与常规的审判理想状态保持一致。

澳大利亚西北大陆架卡那封盆地北部晚-中中新世到上新世发育硅质碎屑岩的三角洲沉积。部分三角洲朵叶体在陆架坡折附近沉积（陆架边缘三角洲），而其他朵叶体在向陆后退或夭折前并没有延伸到同时代的陆架坡折处。陆架边缘三角洲主要集中在研究区北部，陆架边缘坡折的平面形态是从线性变化为向海一侧凸出的形态。陆架边缘三角洲的位置和特征也对边缘进积走向的变化和陆架边缘轨迹产生显著影响。中中新世晚期-晚中新世，南部陆架边缘坡折，总进积距离为13km，不发育陆架边缘三角洲；在陆架边缘三角洲发育区域的北部坡折进积约34km；中部地区的三角洲进积距离没有北部大，以加积特征为主，分布在陆架坡折向陆数千米的范围。这表明陆架边缘轨迹分析的适用条件只有在陆架边缘三角洲发育的地方沉积物供给充足，陆架边缘轨迹特征与相对海平面波动的响应才可靠。在同时代陆坡上发育典型的小规模侵蚀（约400m宽），甚至在三角洲达到陆架坡折前也能看到此侵蚀现象。然而，就在活动陆架边缘三角洲下倾方向的陆坡沟槽显示对下伏地层更大的侵蚀，陆坡沟槽（宽大于1km，深度约100m）比侧向上偏移三角洲沉积中心的同时代侵蚀水道（宽0．7km，深约25m）更宽、更深。本研究表明陆坡沟槽尺寸的变化是由于紧邻陆架边缘三角洲地区沉积重力流产生更大侵蚀的结果。同时，沟槽也进一步侵蚀（达6km）到活动陆架边缘三角洲地区的外陆架。
