We have examined the relationship between the common dopamine D4 receptor (DRD4) exon III repeat polymorphism and infants' behavior measured with the Italian version of the Early and Revised Infancy Temperament Questionnaires (EITQ/RITQ) in 122 Italian neonates at 1 and 5 months of life, when the genetic contribution to the behavior can be more clearly(More)
Addition of ammonium chloride to interferon (IFN)-treated mouse L cells has been reported to reduce the antiviral state. Because (2'-5')-(A)n synthetase and (2'-5')-(A)n-dependent endoribonuclease (RNase L) activities have been implicated in the establishment of the antiviral state, we wish to ascertain if ammonium ions will also impair the IFN-elicited(More)
A (2'-5')An synthetase activity was isolated from human placental extracts by affinity chromatography on poly(rI) . poly(rC)-agarose. The oligonucleotide (2'-5')An was identified by (1) chromatography on PEI-cellulose and DEAE-cellulose, (2) inhibition of polypeptide synthesis in lysed rabbit reticulocytes (3) competition of the binding of(More)
