Unexpected structural diversity in DNA recombination: the restriction endonuclease connection.
Transposition requires a coordinated series of DNA breakage and joining reactions. The Tn7 transposase contains two proteins: TnsA, which carries out DNA breakage at the 5' ends of the transposon, and TnsB, which carries out breakage and joining at the 3' ends of the transposon. TnsB is a member of the retroviral integrase superfamily whose hallmark is a conserved DDE motif. We report here the ...
متن کاملUnexpected relationship between plasma homocysteine and intrauterine growth restriction.
BACKGROUND Moderate hyperhomocysteinemia is considered a risk factor for thrombosis and atherosclerosis. We hypothesized that higher maternal and newborn homocysteine concentrations in plasma would increase the risk of intrauterine growth restriction through placental thrombosis. METHODS We carried out a case-control study that included all cases born at our institution over a 2-year period w...
متن کاملRestriction fragment length polymorphism analysis following unexpected Mycoplasma hyopneumoniae diagnosis in a gilt multiplication herd
Lung tissue from multiple pigs from a serologically negative gilt multiplication barn unexpectedly tested positive for Mycoplasma hyopneumoniae by polymerase chain reaction (PCR) and fluorescent antibody test. While sporadic coughing, dyspnea, and unthriftiness were noted on initial examination, the clinical presentation was atypical of mycoplasmal pneumonia. A detailed diagnostic investigation...
متن کاملNeutron Contamination Unexpected Dose in Varian LINAC
Introduction: Neutron contamination is very harmful for the patients receiving radiation therapy due to the high relative biological effect of neutrons. Medical linear accelerators head are made up of materials with high atomic numbers, and High-energy photons interaction with heavy materials can produce neutron contamination. In this study, neutron equivalent dose, neutron spe...
