As an application, our results enable us to construct infinitely many pairs of cospectral graphs and also integral graphs.
Urethralduplication is a rare condition occurs as a congenital malformation either independently or in the setting of other congenital malformations such as caudal duplication syndrome. Its prevalence becomes even rarer if it manifests as two side-by-side tracts in coronal plan.Nonetheless, we introduce a unique presentation of complete coronal urethral duplication accompanied by astoundin...

We aimed to determine whether infection with virulent H. pylori preceded precancerous gastric hypochlorhydria and atrophy in gastric cancer relatives and quantify the extent of virulence factor evolution. EXPERIMENTAL DESIGN H. pylori strains from 51 Scottish gastric cancer relatives were char...
