十三、关于割胶效率的研究割胶时要控制割胶的水平深度以避免伤树。实际上胶工凭自己的经验掌握到割胶割多深才安全和预计胶树能排多少胶。这并不意味着乳管系统被充分有效地利用了,就一定长度的割线来说,为了达到充分高的采胶效率应该尽量割开最多的乳管列。某一树皮横切面上的乳管总数可估算为nfG,n代表乳管列数目,f代表一个乳管列内乳管的平均密度(乳管数/毫米),G代表茎围。乳管横切面的总面积是nfG(πr~2),r代表乳管半径。

Haim-Munk syndrome (HMS) is a rare autosomal recessive disorder characterized clinically by abnormal palmoplantar hyperkeratosis and destruction of the periodontium, with hallmarks of onychogryphosis and arachnodactyly. Germline mutations in the lysosomal protease cathepsin C gene (CTSC)have been described in a single patient with HMS and in several individuals with the clinically related disorderPapillon-Lef` evre syndrome (PLS). We describe a patient with HMS. We have analysed the cathepsin C gene in the proband and her mother. Sequence analysis of CTSC in the proband revealed a homozygous mutation at codon 196 (587T → C) within exon 4 that altered the conserved leucine to proline (Leu196Pro), whereas the patient’ s mother was heterozygous for that mutation. The same mutation has previously been described in an unrelated Brazilian family with PLS. An identical single missense mutation in the cathepsin C gene may underlie both PLS and HMS. These findings confirm that HMS and PLS are allelic variants of cathepsin C gene mutations and suggest that other factors (environmental or genetic) may be important determinants of the clinical phenotype of HMS and PLS.

In mammalian skeletal muscle there are four carboxylases involved in several biochemical processes like gluconeogenesis, tricarboxylic acid cycle anaplerosis, metabolism of fatty acids and metabolism of various amino acids. It has been shown that biotin deficiency reduces body weight at the expense of muscular mass. When necessary, the liver uses skeletal muscle protein to provide glucose and amino acids to organs in need of such compounds. In this paper we analyzed carboxylase specific activities in hind limb skeletal muscle of 3 weeks old BALB/c male mice, at 0, 1, 4, 7, and 14 days of a specific diet with different biotin concentrations. Biotin was used at 0.0, 1.8 or 98.2 mg per kg of food;and was referred to as biotin deficient, sufficient and supplemented, respectively. Water and food supply and consumption by the three groups of mice were the same. Therefore, the observed effects were directly related to biotin ingestion. The body weight of biotin supplemented mice was the same as the body weight of mice in the biotin sufficient group, while biotin deficiency caused body weight reduction after 7 days of biotin depletion. We found that the total protein concentration in the vastus lateralis muscle is associated with the biotin content in the diet. After 7 days, the muscle total protein content was lower in mice of the biotin deficient group while it was higher in the mice from the biotin supplemented group

Aims The field of ecohydrology is providing new theoretical frameworks and methodological approaches for understanding the complex interactions and feedbacks between vegetation and hydrologic flows at multiple scales. Here we review some of the major scientific and technological advances in ecohydrology as related to understanding the mechanisms by which plant-water relations influence water fluxes at ecosystem, watershed and landscape scales. Important findings We identify several cross-cutting themes related to the role of plant-water relations in the ecohydrological literature, including the contrasting dynamics of water-limited and water-abundant ecosystems, transferring information about water fluxes across scales, understanding spatiotemporal heterogeneity and complexity, ecohydrological triggers associated with threshold behavior and shifts between alternative stable states and the need for long-term data sets at multiple scales. We then show how these themes are embedded within three key research areas where improved understanding of the linkages between plant-water relations and the hydrologic cycle have led to important advances in the field of ecohydrology: upscaling water fluxes from the leaf to the watershed and landscape, effects of plant-soil interactions on soil moisture dynamics and controls exerted by plant water use patterns and mechanisms on streamflow regime. In particular, we highlight several pressing environmental challenges facing society today where ecohydrology can contribute to the scientific knowledge for developing sound management and policy solutions. We conclude by identifying key challenges and opportunities for advancing contributions of plant-water relations research to ecohydrology in the future. © The Author 2011.

[背景]产前暴露于双酚A（BPA）及邻苯二甲酸酯会影响胎儿发育；然而该类研究很少，且得出的结果不一致。[目的]对一个西班牙出生队列中488对母婴进行研究，评估产前暴露于BPA及邻苯二甲酸酯是否与胎儿发育相关。[方法]检测第一和第三孕期两次尿液样本中BPA及8种邻苯二甲酸酯[4种邻苯二甲酸二（2-乙基己基）酯代谢物（DEHPm），邻苯二甲酸单卞酯（MBzP）以及3种低分子量邻苯二甲酸酯代谢物（LMWPm）]。另外，估计股骨长度（fL）、头围（HC）、腹围（AC）、双顶径（BPD）的生长曲线，估计孕期（12—20周，20～34周）的胎儿体重，并测量出生体重、出生长度、出生头围以及胎盘重量。[结果]总体上，结果并不支持孕期暴露于BPA或DEHPm与胎儿发育参数相关。产前MBzP暴露与20～34孕周的fL呈正相关，MBzP浓度每增加一倍，平均fL增加3．7％（95％CI：0．75，6．63％）。MBzP与男婴出生体重呈正相关（48g；95％CI：6，90），但在女婴中没有相关性（-27g；95％CI：-79，25）（交互作用P=0．04）。LMWPm邻苯二甲酸单丁酯（MnBP）与12—20孕周的HC呈负相关[平均HC降低了4．88％（95％CI：-8．36，-1．36％）]。[结论]本研究首次将暴露生物标志重复测量值与胎儿期多种发育参数相结合，发现暴露于BPA或邻苯二甲酸酯与胎儿发育不相关。邻苯二甲酸酯代谢物MBzP与MnBP与部分胎儿发育参数相关，但这些结果还需要重复验证。

背景Sugammadex是一种具有特异结构的γ-环糊精，能选择性地与肌松药结合快速逆转罗库溴铵所致的神经肌肉阻滞，并较小程度地逆转维库溴铵所致的神经肌肉阻滞。该研究中，我们对比了行择期手术的患者中sugammadex和新斯的明对逆转维库溴铵所致神经肌肉阻滞的作用。方法年龄≥18岁，ASA分级I-Ⅲ级拟行择期手术的患者，在七氟醚／阿片类镇痛药麻醉下给予插管剂量维库溴铵（0．1mg／kg），如有必要，在4个成串刺激（train—of-four，TOf）中第二个颤搐波（T2）恢复时给予的0．02-0．03mg／kg的维持剂量。用加速肌动监测仪（TOf-Watch@SX监测仪，先灵-葆雅，爱尔兰都柏林）监测神经肌肉阻滞。术毕，在最后一次给予维库溴铵后咒恢复时，给患者随机静脉注射sugammadex（2mg／kg）或新斯的明（50μg／kg）加格隆溴铵（10μg/kg）。从注药开始至TOf比值恢复至0．9的时间作为主要有效终点。结果Sugammadex组TOf比值恢复至0．9的时间明显快于新斯的明组（分别为2．7分钟[95％置信区间，CI：2．2—2．3分钟]和17．9分钟[95％CI：13．1—24．3分钟]，P〈0．0001）。Sugammadex组TOf恢复至0．8和0．7的平均恢复时间也明显缩短。使用两种药物后均未出现严重不良事件或不可预料的副作用。结论Sugammadex逆转维库溴铵所致神经肌肉阻滞的作用明显快于新斯的明。

We have developed a dry transfer method that allows graphene to be transferred from polymer- thyl-methacrylate (PMMA)/Si (silicon) substrates on commercially available hexagonal boron ni- tride (hBN) crystals. With this method we are able to fabricate graphene devices with little wrin- kles and bubbles in graphene sheets, but that do not degrade the electronic quality more than the SiO2 substrate does. for hBN to perform the function described above substrate cleanliness is critical to get high quality graphene devices. Using hBN as a substrate, graphene exhibits enhanced mobility, reduced carrier inhomogeneity, and reduced intrinsic doping compared to graphene on SiO2 substrate.
