Large Meningioma in an Infant
Abstract Background Histologically confirmed meningiomas in first year of life are quite rare. However, review of the sporadic cases in the literature reported meningioma in infants. Those have unique features in common. Case presentation An 11 month-old Iranian male infant presented with a several weeks history of decrease in movement of his right sided upper and lower extremities. Brai...
متن کاملLarge plasmids of avian Escherichia coli isolates.
The plasmid DNA of 30 Escherichia coli isolates from chickens was extracted and examined using techniques designed to isolate large plasmids. This plasmid DNA was examined for the presence of certain known virulence-related genes including cvaC, traT, and some aerobactin-related sequences. Seventeen of the 30 isolates contained from one to four plasmids greater than 50 kb in size. Eleven of the...
متن کاملSite-directed mutagenesis of large plasmids.
A protocol combining recombination PCR and long-distance PCR is demonstrated to be highly accurate and rapid for site-directed mutagenesis of large (> 10 kb) plasmids. Application of this protocol to the generation of mutant rabies virus glycoproteins expressed by the baculovirus/insect cell system illustrates the usefulness of this approach in facilitating structure-function relationships in t...
متن کاملFattiviracins, Antiviral Antibiotics Produced by an Actinomycete
Most of the successes in the development of antivirals active against herpes viruses have been achieved with synthetic nucleoside analogues. It is well known that a synthetic chemotherapeutic agent, acyclovir, studied by Elion et al.1, 2), (awarded the Nobel Prize in the field of Physiology or Medicine, 1988), is the best medicine for herpes virus infections. Acyclovir has virus-specific activa...
متن کاملIntegration of pT181-like tetracycline resistance plasmids into large staphylococcal plasmids involves IS257.
Four large staphylococcal plasmids ranging in size from 31 to 82 kbp have been shown to mediate tetracycline resistance via an integrated copy of the tet(K)-encoding plasmid pT181 which was flanked by copies of the insertion element IS257. In two cases, IS257 elements interrupted the repC reading frame of pT181 and an 8-bp sequence from within the repC gene was duplicated at the interrupted sit...
