Sexual dimorphism requires the integration of positional information in the embryo with the sex determination pathway. Homeotic genes are a major source of positional information responsible for patterning along the anterior-posterior axis in embryonic development, and are likely to play a critical role in sexual dimorphism. Here, we investigate the role of homeotic genes in the sexually dimorp...

Muscular dystrophy (MD) is the most common genetic lethal disorder in children. Mutations in dystrophin trigger the most common form of MD, Duchenne, and its allelic variant Becker MD. Utrophin is the closest homologue and has been shown to compensate for the loss of dystrophin in human disease animal models. However, the structural and functional similarities and differences between utrophin a...

The homeotic genes in Drosophila melanogaster are aligned on the chromosome in the order of the body segments that they affect. The genes affecting the more posterior segments repress the more anterior genes. This posterior dominance rule must be qualified in the case of abdominal-A (abd-A) repression by Abdominal-B (Abd-B). Animals lacking Abd-B show ectopic expression of abd-A in the epidermi...

Compact fuzzy topological spaces were first introduced by Chang [3]. o-compact fuzzy topological spaces were introduced by Gantner et al. [4]. Abd El-Monsef et al. [1] introduced the notion of e-aimost compact fuzzy topological spaces. Mashhour et al. [8] introduced the notion of bifuzzy topological spaces and defined the notion of o-compactness in those spaces. In this paper, we obtain some ne...

In the article ''Bariatric Bypass Surgery to Resolve Complicated Childhood Morbid Obesity: Case Report Study'', which appeared in Volume 94, Issue 49 of Medicine, Dr. Elrazek's name was incorrectly presented as Abd Elrazek M. Ali Hussein when it should have read Abd Elrazek Abd Elrazek. The article has since been corrected online.

In this paper, vowel epenthesis in Urban Hijazi Arabic is analysed as a process of gradual structural build-up. Harmonic Serialism, derivational framework Optimality Theory, provides the theoretical foundation to illustrate arguments. Rather than epenthesising an entire all at once, featural structure progressively increases successive steps. This accumulation continues until required quality a...

In Drosophila the Abdominal-B (Abd-B) domain of the bithorax complex specifies the identities of several posterior abdominal segments, comprises homeo-protein-coding regions and cis-regulatory regions, and extends from infra-abdominal-5 (iab-5) to iab-8, inclusive. Mutations that eliminate the Abd-B domain act as late embryonic lethals and result in transformations of posterior abdominal segmen...
