molecular dynamics simulations of selforganization of the structure of model biomimetic polymers by using the molecular dynamics method the problem of macromolecules folding into spatial structures is examined the freely jointed polymer chain with strong covalent bonds where vanderwaals forces act between the units of the chain is considered conditions for the formation of different spatial structures resembling the structures called alphahelices betasheets and double helices found in biomolecular systems are determined infrarenal aortic rupture in association with a contiguous polymicrobial intraabdominal abscess including eikenella corrodens aortic rupture in association with a contiguous intraabdominal abscess is rare we report an unusual case of aortic rupture in association with a polymicrobial abscess and review the related literature cultures grew eikenella corrodens a rare intraabdominal pathogen as well as betahemolytic streptococcus and s viridans the patient was successfully managed by aortic ligation followed by an extraanatomic bypass
