Superior laryngeal artery (SLA) is one of the main branches of the superior thyroid artery that its main function is to supply blood to the larynx. This artery is accompanied by the internal branch of superior laryngeal nerve; this relation has anatomical and surgical significance. In this paper, a case of anomalous origin of the superior laryngeal artery is reported. Abnormal origin of SLA fro...

Increasing number of air travellers in recent years and the emergence of multi-airport cities throughout the world has made the behaviour of travellers regarding the choice of the origin airport even more important. Analysis of this behaviour helps for a better future planning and development of competing airports as an important element of their demand prediction. In this paper, particular emp...

In eukaryotes, the origin recognition complex (ORC) heterohexamer preferentially binds replication origins to trigger initiation of DNA replication. Crystallographic studies using eubacterial and archaeal ORC orthologs suggested that eukaryotic ORC may bind to origin DNA via putative winged-helix DNA-binding domains and AAA+ ATPase domains. However, the mechanisms how eukaryotic ORC recognizes ...

measurements of pb, cu, zn, as, ni, hg, and fe heavy metals and major elements and components such as ca, hco3, so4, na, k, mg and cl in soluble rain fractions were performed on rainwater collected at arak plain during the rainy seasons of 2012. concentrations of the heavy metals in the soluble fractions decreased for fe, pb, zn, ni, cu, as and hg, respectively and the major elements and compon...

Recently, two 2-dimensional (2D) gel techniques, termed neutral/neutral and neutral/alkaline, have been developed and employed to map replication origins in eukaryotic plasmids and chromosomal DNA (1-11). The neutral/neutral technique, which requires less DNA for analysis, has been preferentially used in recent studies. We show here that the signal predicted for an origin is not detected using ...

A 30-kb region surrounding the replication origin in Caulobacter crescentus was analyzed. Comparison to the genome sequence of another alpha-proteobacterium, Rickettsia prowazekii, revealed a conserved cluster of genes (RP001, hemE, hemH, and RP883) that overlaps the established origin of replication in C. crescentus and the putative origin of replication in R. prowazekii. The genes flanking th...

Many empirical studies show that there are unusual clusters of palindromes, closely spaced direct and inverted repeats around the replication origins of herpesviruses. In this paper, we introduce two new scoring schemes to quantify the spatial abundance of palindromes in a genomic sequence. Based on these scoring schemes, a computational method to predict the locations of replication origins is...
