| 1 | 精子尾部和头部疼痛的传奇:影响精子头部、颈部和尾部的精子病理学预后意义的观念转变显示文摘本文对精子形态和活力问题导致的严重男性不育的各种精子病理学的最新预后意义研究进行了综述。严重的弱精症是男性不育症的主要原因之一,即精子不能到达卵母细胞和/或正常穿透。在卵胞浆内单精子注射(ICSI)之前确定精子无动力的结构因素是非常重要的,因为精子无动力是治疗这些病人的关键因素。治疗这些患者时,要用体外培养的方法挑选有活力的精子或激发精子的活力,以免使用的是坏死的精子细胞。这种改进之后,受精和妊娠结果会显著改善。治疗弱精症患者时,需要提前鉴定遗传显型,并充分告知患者治疗结果和风险。畸形精子症是严重影响生育预测的一个精子特征,主要表现为精子头部和颈部异常。染色质凝聚缺陷和顶体发育不全是两种最常见的严重畸形精子症的表现。显微选择精子和ICSI之前评估精子质量的新方法的开发和应用,确保了对精子病理学超微结构的鉴定,不仅仅只是学术兴趣,同时也是选择治疗方法的一种重要途径。本文回顾了精子各部分在正常受精和早期胚胎发育过程中所发挥的不同作用,探讨了辅助生殖技术如何转变了我们对不正常精子头部、颈部、中片和尾部的病理学的预后意义的认识。 | Hector E Chemes Cristian Alvarez Sedo | 2012 | Asian Journal of Andrology2012，14，1： | 16 |
| 2 | A Three-Dimensional Range-Free Localization Algorithm Based on Mobile Beacons for Wireless Sensor Networks显示文摘In wireless sensor networks (WSNs) the position information of individual nodes is a matter of vital importance because allows the implementation of necessary network functions such as routing, querying and other applications. The objective of this paper is to propose an algorithm of three-dimensional distributed range-free localization for WSNs, using a mobile beacon (MB) equipped with a rotary and tilting directional antenna. This algorithm, denominated as the three-dimensional azimuthally defined area localization algorithm (3D- ADAL), is executed in each sensor node and is based only on the analysis of the information received from the MB, therefore is energy efficient and contributes to extend the lifetime of the sensor network. Additionally the proposed algorithm has the advantage of being simple and economical. The simulation results show that the proposed algorithm is a practical, effective and accurate method for a three-dimensional location of sensor nodes in a WSN. | GUERRERO E ALVAREZ J RIVERO L | 2010 | Computer Aided Drafting,Design and Manufacturing2010，20，1： | 3 |
