Corynebacterium pyrogenes; a biochemical and serological study

The study comprises 136 strains of Corynebacterium pyogenes originating from cattle (105), swine (20), sheep (1), and insects (10). For comparison 2 strains of human origin and 1 strain of Gorynebacterium hemolyticum were examined.One of the bovine strains was atypical, being gelatinase-negative, otherwise the strains of Cb. pyogenes were found to be biochemically identical apart from minor deviations in fermentation patterns (Table 1). Neither were antigenic differences demonstrated (gel diffusion analyses, Figs. 1 and 2).Both of the human strains agreed biochemically with Cb. pyogenes (Table 1). By gel diffusion cross analyses one of them was found to be identical with Cb. pyogenes, the other not, though anti-genically related to it (Fig. 2).Gb. hemolyticum deviated biochemically as well as serologically from Gb. pyogenes, but the 2 organisms shared antigenic determinants (Fig. 3).     

老年农民工人力资源开发研究

开发老年农民工人力资源不仅是老年农民工自我发展的需要,也是社会发展的必须。老年农民工与青年农民工可以优势互补,发挥老年农民工的余热既可消化农村剩余劳动力,又可促进城市化进程。     

走出人力资源管理的误区

人力资源管理从传统的人事管理发展到现在的战略性人力资源管理，对企业的生存和发展发挥着越来越重要的作用。因此，国内外学者也越来越关注对人力资源管理的研究，但在人力资源管理观念上还存在着一些误区。文章阐述了人力资源管理的特点，比较了现代人力资源管理与传统人事管理的区别，从而给人力资源管理重新定位。

Assessing freshwater fish sensitivity to different sources of perturbation in a Mediterranean basin

Abstract –  The accuracy of bioassessment programmes is highly limited by the precision of the systems used to derive sensitivity–tolerance values for the organisms used as indicators. We provide quantitative support to the objective evaluation of freshwater fish species sensitivity to different sources of disturbance, accounting for co-variation issues not only between perturbations and natural gradients (especially river size), but also between different perturbations. With this aim, we performed two different principal component analyses: (i) on a general environmental matrix to obtain a perturbation gradient independent of river size effects and (ii) on human impairment-related variables to extract independent synthetic perturbation gradients. Then, we checked each species responses to those gradients to assess their sensitivity–tolerance through an available-used chi-squared analysis in the first approach and through a t -test/ ancova analysis in the second one. In this way, we obtained sensitivity–tolerance which could be included in future bioassessment tools, enabling effective evaluations.     

母乳中VA与婴幼儿健康研究进展

母乳中含有多种VA,如视黄醇、β-胡萝卜素、β-隐黄质、α-胡萝卜素、番茄红素及叶黄素等,且母乳初乳、过渡乳和成熟乳中VA的含量不同,但总体上VA含量随着泌乳期的延长而降低。如母乳中含量最高的VA视黄醇,其在初乳、过渡乳、成熟乳中的含量分别为478～1 920、440～1 270、178～825 μg/L。母乳中VA含量除受泌乳时间影响外,还与地域、乳母膳食及母乳脂肪含量等有关。本文重点介绍不同国家/地区母乳中VA的种类、含量、影响因素及其健康作用（视觉健康、免疫健康和生长发育等）,以期为婴幼儿配方乳粉的发展提供参考。
