Fourth World Conference on Women: the Namibian perspective

This consideration of some of the issues raised at the Fourth World Conference on Women (WCW) from a Namibian perspective begins by mentioning the pernicious nature of domestic violence and briefly summarizing some of the main points raised at a 1994 symposium on domestic violence. The discussion continues by noting that Namibia's report for the WCW reaffirms that it is crucial for women to be involved in the decision-making process at all levels. Next, the paper notes that traditional male attributes of strength are losing their importance in a world that values mental alertness, intuition, and traditional female qualities of love and service. This has led to a call for a transformation of society supported by the education of women and their economic empowerment. The essay ends by defining an empowered person as possessing a belief in the ability of human intervention to change the world, a sense of self-worth, a sense of the self as a viable agent of change, and a notion of what constitutes a better life.     

缺氧对脑星状细胞GAPDH和β—Actin基因表达的影响

目的：样本ＲＮＡ加样量的差异是影响Ｎｏｒｔｈｅｒｎ杂交ＲＮＡ分析和反转录ＰＣＲ（ＲＴ－ＰＣＲ）半定量分析的重要因素。因５－磷酸甘油醛脱氢酶（ＧＡＰＤＨ）和β肌动蛋白（β－ａｃｔｉｎ）ｍＲＮＡ水平一般相对恒定,常用于基因表达研究时样本加样量的校正。但有报道表明某些因素对ＧＡＰＤＨ和β－ａｃｔｉｎ的ｍＲＮＡ水平有一定影响。脑星状细胞（ＡＣ）是近年来神经科学的研究热点之一,有关其基因的研究得到广泛的重视     

A massive phytoplankton bloom induced by an ecosystem-scale iron fertilization experiment in the equatorial Pacific Ocean

The seeding of an expanse of surface waters in the equatorial Pacific Ocean with low concentrations of dissolved iron triggered a massive phytoplankton bloom which consumed large quantities of carbon dioxide and nitrate that these microscopic plants cannot fully utilize under natural conditions. These and other observations provide unequivocal support for the hypothesis that phytoplankton growth in this oceanic region is limited by iron bioavailability.     

Research fraud: false data confessed

Joseph Cort, a researcher at Mount Sinai Medical School in New York City from 1976 to 1980, has admitted fabricating data on the synthesis of hormone analogues. Cort's research at Mount Sinai was supported principally by a contract from Vega Biochemicals, though he received a small amount of support under a National Institutes of Health grant to his department.     

Genetic engineering: regulation issue is resurrected by EPA

The Environmental Protection Agency is asserting regulatory control over the commercial production of genetically-engineered microorganisms, such as oil-eating bacteria, intended for release into the environment. EPA's legally-complex claim that such organisms are "new chemical substances," and thus subject to the Toxic Substances Control Act (TSCA), raises a challenge to the adequacy of regulation by the National Institute of Health's Recombinant DNA Advisory Committee (RAC) over the commercial and ecological implications of environmental release. Industry, which has been voluntarily adhering to the RAC guidelines, is reluctant to challenge application of the relatively lenient TSCA requirements but eager to see the legal uncertainties resolved.
