朱淑真诗词在宋代传播与接受考

朱淑真是我国女性文学史上一位重要人物，其诗词有很高的思想性和艺术性，但她的文名在宋代并不彰显。本文从宋人口传、专集出版、选本、评论等几方面考究当时对朱淑真诗词传播与接受的情况。

技术合作博弈中的政府补贴政策研究

建立了在存在政府政策保护的情况下,两个国家间的三阶段博弈模型.结果表明:(1)政府的R＆D补贴提高了企业的R＆D投资,但不会减少竞争企业的R＆D投资.而且,企业在R＆D中的投资不能影响其竞争企业的产出;(2)当几乎不存在技术交流与合作时,企业将在R＆D中过度投资;当两个企业间存在技术交流与合作时,企业在R＆D中投资不足;(3)当技术引进所占比例较大时,政府必要的补贴和保护还是必要的;当技术创新主要靠自主研发时,政府可以少补贴或者不补贴.     

The effect of cycloheximide on nuclear uH2A content

Summary The effect of intraperitonal cycloheximide administration on acid-soluble rat liver chromatin proteins has been investigated by electrophoresis in acetic acid-urea polyacrylamide gels. A nonhistone protein, which migrates between oxidized histone H3 and histone H1 has been found tobe increased in amount following cycloheximide treatment. This protein seems to be identical with semihistone protein H24 (uH2A). A possible relationship of uH2A to the inhibition of rRNA synthesis is discussed.This work was supported by the Turkish Scientific and Technical Research Council (TUBITAK) Project No. TAG 339     

How retinoids regulate breast cancer cell proliferation and apoptosis

Breast cancer still remains a major problem in its incidence, morbidity and mortality; therefore, more effective strategies for its prevention are urgently needed. Retinoids, natural and synthetic derivatives of vitamin A, possess antiproliferative and proapoptotic properties, making them a promising class of chemopreventive agents against breast cancer. The efficacy of all-trans retinoic acid, 9-cis-retinoic acid, LGD1069 (Targretin, bexarotene), and N-(4-hydroxyphenyl)retinamide (fenretinide) as breast cancer chemopreventive agents is being studied. A better understanding of the molecular mechanisms of action of these agents should lead to improvements in their clinical application. In this review, we discuss the mechanisms by which retinoids exert their antiproliferative and apoptotic effects in breast cancer cells.Received 5 January 2004; received after revision 9 February 2004; accepted 12 February 2004     

中国清洁生产在制浆造纸行业实施十年回顾

回顾了《清洁生产促进法》立法之前清洁生产在我国的发展史,以及在此期间政府、企业、广大技术人员所做出的努力.十年前在联合国环境规划署的推动下,我国清洁生产首先在制浆造纸等行业启动并推行,北京工商大学项目组也做了很多具体工作,并为我国在国际上争得了荣誉.今天清洁生产已深入到各行各业的基层,并遍及全国,生态工业园区、循环经济等模式的成功示范,使清洁生产理论在实践中获得不断发展.

Melanocortin receptors: their functions and regulation by physiological agonists and antagonists

The melanocortins are a family of bioactive peptides derived from proopiomelanocortin, and share significant structural similarity. Those peptides are best known for their stimulatory effects on pigmentation and steroidogenesis. Melanocortins are synthesized in various sites in the central nervous system and in peripheral tissues, and participate in regulating multiple physiological functions. Research during the past decade has provided evidence that melanocortins elicit their diverse biological effects by binding to a distinct family of G protein-coupled receptors with seven transmembrane domains. To date, five melanocortin receptor genes have been cloned and characterized. Those receptors differ in their tissue distribution and in their ability to recognize the various melanocortins and the physiological antagonists, agouti signaling protein and agouti-related protein. These advances have opened new horizons for exploring the significance of melanocortins, their antagonists, and their receptors in a variety of important physiological functions.

Dealing with a Differentiated Whole: The Philosophy of the WSR Approach

This paper seeks to explore a philosophical ground for the formulation and practice of an Oriental systems methodology, the wuli–shili–renli approach (WSR). Drawing insights from ancient Chinese thought, WSR contends that, in sociotechnical systems design/management, we should investigate and follow wuli, shili, and renli, which constitute a differentiable, dynamic whole. Wuli, shili, and renli condition and determine the fate of our projects, meaning different methods are needed to deal with each differentiable aspect. It also points out that, to deal with wuli, shili, and renli properly, we need to engage in encounters with the "dark side" of Confucianism and with the contemporary tendency of scientism.
