化学发光自显影免疫印迹法（Western Blotting）检测绒山羊皮肤组织中催乳素受体蛋白

采集不同季节绒山羊皮肤组织样品,提取总蛋白,经聚丙烯酰胺凝胶电泳,将电泳结果转移到醋酸纤维薄膜,然后与催乳素抗体结合、辣根过氧化物酶标记二抗结合,后者作用于化学发光底物,暗室中置X-光胶片上自显影数分钟,经显影、定影,得到黑色曝光斑,根据胶片上曝光斑的位置确定出催乳素受体的分子量为87kD。根据不同时期样品黑斑的大小得出各时期催乳素受体表达量与绒毛生长趋势是一致的。     

道路交通驾驶员差异性分类定量研究

驾驶员个体差异是影响城市道路交通运营、效率及安全的一个重要因素之一。为了实现对驾驶员差异性的影响分析,采用驾驶模拟舱研究平台对驾驶员样本进行归类。研究分别选取了反映驾驶员特征的静态驾驶适性和动态驾驶适性两类,共计15个指标。采用因子分析的方法将相关指标归纳为驾驶员的5个类因子,并通过主成份分析的方法找出每类因子中的主导指标,并以此指标作为聚类分析的输入变量。结果表明聚类分析得到的三类驾驶员具有明显的各自特征。     

播种方式对紫花苜蓿＋无芒雀麦人工草地土壤剖面养分分布的影响

采用田间调查取样和室内分析相结合的方法,2007年在内蒙古民族大学农学院试验农场以2年生单播紫花苜蓿、单播无芒雀麦、隔行混播和同行混播人工草地为研究对象,采用分层取样法研究了不同播种方式对土壤理化性质的影响,结果表明：在牧草生长期间单播无芒雀麦草地土壤容重最小,紫花苜蓿草地土壤容重最大;单播无芒雀麦、隔行混播和同行混播草地0～20cm土层有机质含量大于单播紫花苜蓿草地,20～30cm不显著,30～40cm单播紫花苜蓿草地显著增加,分别是隔行混播草地、同行混播和单播无芒雀麦草地的1.11、1.72和1.94倍;速效N单播无芒雀麦草地最低,速效P、速效K单播紫花苜蓿草地最低.     

A genome-wide association study of nonsynonymous SNPs identifies a type 1 diabetes locus in the interferon-induced helicase (IFIH1) region

In this study we report convincing statistical support for a sixth type 1 diabetes (T1D) locus in the innate immunity viral RNA receptor gene region IFIH1 (also known as mda-5 or Helicard) on chromosome 2q24.3. We found the association in an interim analysis of a genome-wide nonsynonymous SNP (nsSNP) scan, and we validated it in a case-control collection and replicated it in an independent family collection. In 4,253 cases, 5,842 controls and 2,134 parent-child trio genotypes, the risk ratio for the minor allele of the nsSNP rs1990760 A --> G (A946T) was 0.86 (95% confidence interval = 0.82-0.90) at P = 1.42 x 10(-10).

Late Eocene of Burma yields earliest anthropoid primate, Pondaungia cotteri.

In April 1978, a fragment of a primate lower jaw containing the second and third molar teeth was found in late Eocene exposures of the Pondaung Hills about 1 mile north-west of Mogaung village in northwestern Central Burma. This approximately 40-Myr-old specimen is the first fossil primate found in Burma since the fragmentary remains of the controversial earliest anthropoids Pondaungia cotteri Pilgrim and Amphipithecus mogaungensis Colbert were recovered more than 50 yr ago. The jaw described here is believed to represent further evidence of P. cotteri. Its recovery from undoubled late Eocene exposures coupled with its salient higher primate characters and excellent state of preservation provides the opportunity to substantiate further that the Pondaung primates of Burma are the earliest known record of the Anthropoidea.
