in this research paper, we applied rituals of social drama processes to find out symbols, decoding and signs in the manegh-al-tair. in our analysis we discovered that birds, instead of humans, are acting as players in the social stage. each of these birds possess some particular characteristics and social statuses, which are attributed to the humans who lived in the attar time (age). to offer m...

introduction: pronuclear size, morphology and orientation are known to affect embryo quality and implantation. the present study was aimed at evaluation of the possible relationship between protamine deficiency with pronuclear morphology and also cleavage and embryo quality. material and methods: semen sample of 160 candidate icsi and ivf couples were analyzed for sperm concentration, and motil...

The cleavage stimulation factor (CstF) is essential for the first step of poly(A) tail formation at the 3' ends of mRNAs. This heterotrimeric complex is built around the 77-kDa protein bridging both CstF-64 and CstF-50 subunits. We have solved the crystal structure of the 77-kDa protein from Encephalitozoon cuniculi at a resolution of 2 A. The structure folds around 11 Half-a-TPR repeats defini...

introduction : activated protein c (apc) inactivates factor v by cleavage of its heavy chain at arg306, arg506, arg679, and lys994. mutational changes, which abolish apc cleavage sites, may predispose thrombosis by altering the inactivation process of factor v.  factor v leiden (arg506glu) has been demonstrated as a strong risk factor for thrombosis. in the current study, we have studied whethe...

It is well established that many metal ions accelerate the spontaneous degradation of RNA. This property has been exploited in several ways to garner information about RNA structure, especially in regards to the location of site-specifically bound metal ions, the presence of defined structural motifs, and the occurrence of conformational changes in structured RNAs. In this chapter, we review th...

This paper examines party preferences in Israel from 1993 to 1999. This period provides a unique ‘natural’ experiment in that the middle was marked by a change from a single-ballot party list to a two-ballot system that included direct election of the Prime Minister. The paper has two goals: (1) to explore the patterns of social cleavage voting in Israel during this period; and (2) to determine...

introduction: the value of embryonic stem-like cells in cloning is obvious. production of cloned animals can be achieved by introduction of these cells into a tetraploid embryo. tetraploid embryo is used as a feeder for development of embryonic stem-like cells and can be produced in vitro by electro-fusion of 2-cell embryos. the aim of this study was to ass,essthe effect of voltage alteration a...
