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...

Homeotic genes are aligned on the chromosome in the order of the segments that they specify along the antero-posterior axis of the fly. In general the genes affecting the more posterior segments repress the more anterior genes, a phenomenon known as "posterior dominance". There is however a noticeable exception to this rule in the central nervous system of Drosophila melanogaster where the post...

This article discusses Arabic expressions referring to God, such as inshallah, mashallah, and alhamdulillah in the 2014 season of Arab version talent show The Voice. It question what extent these are used by various actors show, particular its four jury members three presenters, it tries explain why they use them purpose. analysis is set against background relationship between ‘language’ (in th...

CONTEXT Although chronic beryllium disease (CBD) is clearly an immune-mediated granulomatous reaction to beryllium, acute beryllium disease (ABD) is commonly considered an irritative chemical phenomenon related to high exposures. Given reported new cases of ABD and projected increased demand for beryllium, we aimed to reevaluate the patho physiologic associations between ABD and CBD using two c...

the belief in allah and having the inclination towards him is of the innate human disposition; and human beings have throughout the history sought to know their god and many have undeservingly applied the quest to false gods whom they have worshiped. in order to know allah, some people liken him to human beings or other creatures and even they attribute a body to him; yet others establish absol...

Actin microfilaments regulate the size, shape and mobility of dendritic spines and are in turn regulated by actin binding proteins and small GTPases. The βI isoform of spectrin, a protein that links the actin cytoskeleton to membrane proteins, is present in spines. To understand its function, we expressed its actin-binding domain (ABD) in CA1 pyramidal neurons in hippocampal slice cultures. The...

We have cloned a homologue of the homeotic gene Abdominal-B from the locust Schistocerca gregaria and raised antibodies against the homeodomain and C-terminal flanking region of the encoded protein. This antibody stains the posterior abdomen of the developing Schistocerca embryo from 26% of development onwards, a stage when only the anterior of the abdomen is visibly segmented. By the time segm...

Assurance BasedDevelopment (ABD) is a novel approach to the synergistic construction of critical soware systems and their assurance arguments. InABD, theneed for assurance drives a unique process synthesis mechanism that results in a detailed process for building both soware and an argument demonstrating its fitness for use in given operating contexts. In this paper, we introduce the ABD proc...

Hox genes have been implicated in the evolution of many animal body patterns, but the molecular events underlying trait modification have not been elucidated. Pigmentation of the posterior male abdomen is a recently acquired trait in the Drosophila melanogaster lineage. Here, we show that the Abdominal-B (ABD-B) Hox protein directly activates expression of the yellow pigmentation gene in poster...
