background: the fc receptor like (fcrl) molecules belong to the immunoglobulin (ig) superfamily with potentially immunoregulatoryfunction. among the fcrl family fcrl2 and 4 are predominantly expressed on memory b cells and fcrl1 is a pan- b cell marker. to date, noligand has been identifid for the human fcrl1, 2 and 4 molecules.objectives: cloning, expression, purifiation and structural analysi...

Every dialogue is constrained by a rigid framework, which manifests itself in its linear character (an initial-continuation-counter move structure or question-answer relationship and dismissal-argumentation order of dialogue), illustrates the functional dependencies between sentences sequences sentences. The following study focuses on discourse-pragmatic notion interviewer’s text-forming strate...

Polar Response Particles (PRPs) have been widely studied in the literature, discussing essence of their ambiguity polarity and (dis)agreement reading sys- tems (Pope 1976) what affects preference. In languages like English Farsi, which same particles satisfy both readings, PRPs are ambiguous response to negative initiatives (including questions assertions). on other hand, not only used assertiv...

The present study was an attempt to examine how questioning was treated by EFL instructors and learners at a private language center in Yasouj, Iran. This study also intended to explore the types of questions posed by the EFL instructors and learners in different course levels and to scrutinize the extent to which the instructors’ classroom behaviors were geared towards enhancing the learners’ ...

We describe herein a new transgenic mouse tumor model in which fibroblast growth factor (FGF) receptor activity is selectively inhibited. Tyrp1-Tag mice that develop early vascularized tumors of the retinal pigment epithelium were crossed with tyrp1-FGFR1-DN mice that express dominant-negative FGF receptors in the retinal pigment epithelium to generate bigenic mice. Initial angiogenesis-indepen...

How do users behave if they can tag each other in social networks? In this paper, we answer this question by studying the interactive tagging network constructed by Twitter lists. Twitter lists can be regarded as the tagging process; a user (i.e., tagger) creates a list with a name (i.e., tag) and adds other users (i.e., tagged users) into the list. This tagging network is by nature different f...
