we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...

Genetic studies have identified an unusual transvection process in the Abdominal-B (Abd-B) locus of Drosophila. In some cases distal infraabdominal (iab) regulatory domains continue to activate the Abd-B promoter even when translocated onto different chromosomes. Transvection depends on an approx. 10 kb genomic DNA sequence, termed the transvection mediating region (tmr), located immediately do...

Kādî Abdülcebbâr’ın düşünce dünyası incelendiğinde bunun, Tanrı’nın insanı sorumlu kılabilmesinin imkânı üzerine kurulu olduğu anlaşılmaktadır. Eş deyişle o, teklif merkezli inşa edilen bir evreni ve düzenine sahiptir. Bu yüzden de onun usûlü’d-dîn şeklinde adlandırdığı düşüncesinin içeriğini insanın sorumlulukları oluşturmaktadır. İnsanın bu ise akıl yoluyla kendisine bildirilen yükümlülükler ...

There are many examples within gene complexes of transcriptional enhancers interacting with only a subset of target promoters. A number of molecular mechanisms including promoter competition, insulators and chromatin looping are thought to play a role in regulating these interactions. At the Drosophila bithorax complex (BX-C), the IAB5 enhancer specifically drives gene expression only from the ...

The abdominal-A (abd-A) and Abdominal-B (Abd-B) genes of the bithorax complex (BX-C) specify the identity of most of the Drosophila abdomen. Six different classes of infraabdominal (iab) mutations within the BX-C transform a subset of the parasegments affected by the lack of these two genes. It is thought that these mutations define parasegmental cis-regulatory regions that control the expressi...
