Antioxidant and Anticancer Activities of Selected Persian Gulf Algae

In the present study, the effect of red (Gracillaria corticata), green (Ulva fasciata) and brown (Sargassum ilicifolium) seaweeds alcoholic extract, against five important human cancer cell lines (MCF-7, MDA-MB-231, HeLa, HepG2, and HT-29) proliferation, apoptosis and cell cycle arrest were evaluated. The reducing activity and total polyphenol content were also investigated. MTT assay was used for cytotoxicity test. Morphological alterations were examined using phase contrast, fluorescent and electron microscopy. All the extracts were antiproliferative against all the cancer cell lines, dose-dependently, with G. corticata methanol extract (GCME) having the greatest inhibition activity against MCF-7 cell line. The percentage of apoptosis increased from 18 to 78 %. The cell cycle analysis also showed that GCME can induce apoptosis which confirm by TEM. Algal extract reducing activities were as follows: G. corticata > S. ilicifolium > U. fasciata. The GCME is a good source of potential complementary and alternative functional food for prevention and treatment of cancer.     

Word frequency effects in naming for experienced and previously experienced adult readers of Persian

In a word naming experiment, experienced readers of Persian named high frequency transparent Persian words significantly faster than matched low frequency words. There was no such frequency effect for adults who had, during the past decade or more, very little experience in reading materials in Persian due to immigration to the West. Overall, the previously experienced adults named words significantly slower than their experienced counterparts. The implications of this finding in relation to models of visual word recognition are discussed.     

波斯帝国对希腊城邦政策的演变

公元前 5— 4世纪 ,波斯帝国对希腊城邦世界的政策经历了从武力征服到保持城邦均势的演变。波斯从希波战争中的惨败吸取经验教训 ,及时调整了对希腊城邦的政策 ,这一政策的演变不仅使波斯摆脱了战败的阴影 ,改善并提高了帝国的政治地位 ,而且还利用希腊城邦间的混战来削弱希腊城邦的力量。事实证明 ,均势政策不仅使波斯帝国从中受益 ,而且也充分显示了波斯帝国外交政策的成熟     

以上帝的名义:伊朗文化精神

在伊斯兰教灵知(Irfan)中,人被视为上帝在尘世的代理,这种作用无疑在于他的精神,而非身体。精神的这一方面在东方诸文化(包括波斯文化)的核心与本质中是非常明显的。对一个传统的伊朗人来说,精神首先与神圣生命联系在一起,因此对他来说,文化是在宇宙和人那里表现神圣生命的一个显白的饲子,明确表现在他的文化中的所有方面,包括艺术、音乐、诗歌、散文、建筑、信仰。此外,按照伊朗圣贤的说法,精神与意义和富有意义之世界联系在一起。只有我们身上的精神才能理解事物的意义。神圣精神将意义赋予一切事物。     

北魏平城砖瓦文字简述

北魏平城时期是我国历史上继汉代之后又一个吉语瓦当高峰期。皇家建筑遗址出土的大量瓦文,原汁原味地展示了当时人们的文化水准、书写能力和书体运用情况。近年在大同地区出土的并不算多的北魏砖铭充分证明,在拓跋氏建都平城时期,所有墓中瘗文字砖者,无一不是来自于南朝的贵族以及西来东至的秦凉和两燕的"投化客"。拓跋氏帝室和近族胡(纥骨)、周(普)、长孙、奚(达奚)、伊(伊娄)、丘(丘敦)、亥(侯)、叔孙、车(车焜)等九姓以及"太祖已降,勋著当世,位尽王公"的陆(步六孤)、贺(贺赖)、刘(独孤)、楼(贺楼)、于(勿忸于)、嵇(纥奚)、尉(尉迟)八姓连如此简单的砖铭都没有。但是,公元494年,孝文帝迁都洛阳之后,不仅在洛阳大量出现元姓宗亲和其他代姓贵族的大量墓志,而且在平城也出现了"尉娘"、"苟黑"等代人墓砖。     

Main Issues in Cataloging Persian Language Materials in North America

ABSTRACT

The main problems of cataloging Persian language materials as it is practiced in North America are discussed. The problems are grouped by origin: those that originate from the implementation of the ALA-LC Romanization Tables for Persian; those that occur either because of misleading examples used in that Table's rules for application section, or a lack of functional knowledge of Persian; and those that appear in the treatment of names generally and choice and form of main entry specifically, due to the application of inappropriate rules for Persian names. Suggestions for dealing with these cataloging issues are presented.     

人事档案管理信息化的几点思考

随着社会的不断发展进步,在当前信息化时代,传统的人事档案管理方式和档案信息的开发利用程度已经不能满足日益变化的人事工作需求,迫切需要与时俱进,进行创新与变革,实现信息化、现代化.     

基于ARM11的墙地砖色差检测装置研究

研究了一种基于ARM11处理器、采用塔形聚类算法和欧式距离公式进行色差测量的墙地砖色差检测装置,它采用CMOS摄像头进行图像采集,软件用的是Linux操作系统。实验结果表明,该装置能满足墙地砖色差的非接触式检测。     

汉代瓦当和玺印中的均衡设计

汉瓦当艺术和汉玺印艺术是绚烂夺目的汉代艺术设计形式中迷人的一枝双苞奇葩。两者虽不为同一目的而产生,但具有很多相通之处。它们在固定而规则的二维平面中对字体的变化、设计,对图形的使用,达到了非常高的水平,汉代的匠人们(设计师)对均衡、和谐的理解深刻而全面,他们在实践中反复完善着自己的均衡之计,创造出令人叹为观止的均衡之美。     

The role of orthographic and phonological processing skills in the reading and spelling of monolingual Persian children

The main objective of the present study was to examine the contribution of phonological and orthographic skills to Persian reading and spelling. The Persian language is of interest because it has very consistent grapheme-to-phoneme correspondences, but somewhat inconsistent phoneme-to-grapheme correspondences. Reading, spelling, phonological, and orthographic skills were tested in a sample of 109 monolingual Persian students (mean age = 8;1, SD = 4 mo) attending Grade 2 in Iran. The results showed that although monolingual Persian children relied both on phonological and orthographic skills, phonological skills were a strong predictor for both reading and spelling. Another objective of the study was to compare children’s spelling performance in terms of phoneme-to-grapheme (PG) consistencies. As expected, children spelled PG-consistent words more accurately than PG-inconsistent words. Moreover, they relied more on orthographic skills for spelling PG-inconsistent words than for spelling PG-consistent words. The results are discussed in terms of the differential effect of orthographic consistency on reading and spelling.
