abu al-al?’ al-ma’arri has presented his specific thought and viewpoint in arabic classical literature. he lived at the time when arabic literature was at its zenith of richness and maturity. this literary and thinking figure has affected the literary men after him in differing ways. contemporary poets, relying on his literature, have promoted their own literary innovations, and thereby have en...

The Drosophila larval cardiac tube is composed of 104 cardiomyocytes that exhibit genetic and functional diversity. The tube is divided into the aorta and the heart proper that encompass the anterior and posterior parts of the tube, respectively. Differentiation into aorta and heart cardiomyocytes takes place during embryogenesis. We have observed living embryos to correlate morphological chang...

the ḥadīth, “backbiting is more severe than adultery” (al-ghaybatu ashaddu min al-zinā), quoted from the apostle of allah (s.a.w.), by four of his companions: abū dhar al-ghifārī, abū sa‘īd al-khudrī, jābir b. ‘abd allāh al-anṣārī, and anas b. al-mālik is reported in the shī‘ī and sunnī sources – except for the kutub al-‘arba‘a and ṣiḥāḥ al-sitta. while analyzing and explaining the text of the ...

Many important processes in eukaryotic cells involve changes in the quantity, location and the organization of actin filaments [1] [2] [3]. We have been able to visualize these changes in live cells using a fusion protein (GFP-ABD) comprising the green fluorescent protein (GFP) of Aequorea victoria and the 25 kDa highly conserved actin-binding domain (ABD) from the amino terminus of the actin c...

BACKGROUND In Drosophila, the gonads are composed of two cell populations: the germ line, derived from the pole cells, and a somatic component, derived from the mesoderm of abdominal segments 5-8. Formation of the gonad requires the function of a specific homeotic gene, abdominal-A (abd-A). Other genes of the bithorax complex, Ultrabithorax (Ubx) or Abdominal-B (Abd-B), cannot substitute for th...

The Abdominal-B (Abd-B) gene of the bithorax complex (BX-C) of Drosophila controls the identities of the fifth through seventh abdominal segments and segments in the genitalia (more precisely, parasegments 10-14). Here we focus on iab-5, iab-6 and iab-7, regulatory regions of Abd-B that control expression in the fifth, sixth and seventh abdominal segments (parasegments 10-12). By analysis of pa...

Ingolfiella arganoi sp. n. from Abd al Kuri Island in the Arabian Sea is described from two specimens, a male and a female. The western shore of the Indian Ocean was hitherto a vacant spot in the distribution of circumtropical shallow marine interstitial ingolfiellids and therefore the location of the new species fills a meaningful gap in the geography of the family. Morphologically, the new sp...

“word-order” is one of the most central concepts in ancient rhetoric and islamic ilm-al-balagha. this article attempts to compare this concept in these two rhetorical systems. in the first section, “word-order” as part of a more pervasive concept of “composition” is discussed. since dionysius of halicarnassus’ “on literary composition” represents the most comprehensive attitude to “word-order”,...

the ode “buka'iyya ila shams haziran” is considered as one of the critical and extreme poems of abd al-wahhab al-bayati, the significant contemporary arab literary figure (1999-1926). applying a simple language which is also vague in some aspects, the poem is allocated to presenting social and political conditions of arab countries and analyzing the reasons associated with 1967 june defeat. as ...
