The oxidative metabolism of methionine by a transaminative pathway was studied in rat and monkey tissue homogenates. Methionine was shown to undergo transamination followed by subsequent oxidation of its a-keto acid, a-keto-y-methiolbutyrate, to carbon dioxide in rat and monkey liver homogenates. Considerable transamination of methionine was observed in monkey kidney homogenates, but little of ...

Distinctive thymidine (dT) kinase molecular forms are present in mouse, human, and monkey mitochondria. Disk polyacrylamide gel electrophoresis (disk PAGE) analyses have shown that the mitochondrial-specific dT kinases differ from cytosol dT kinases in relative electrophoretic mobilities (Rm). Furthermore, the mouse mitochondrial dT kinase differs in Rm value from primate mitochondrial dT kinas...

Behavioral and electrophysiological evidence suggests a gradual, experiencedependent specialization of cortical face processing systems that takes place largely in the 1st year of life. To further investigate these findings, event-related potentials (ERPs) were collected from typically developing 9-month-old infants presented with pictures of familiar and unfamiliar monkey or human faces in 2 d...

A reverse transcriptase-containing virus has recently been isolated from a squirrel monkey (Saimiri sciureus). Molecular hybridization studies demonstrate that the squirrel monkey retrovirus (SMRV) is endogenous to this New World primate, yet lacks detectable nucleotide sequence homology with cellular DNAs of representative Old World primates or with the genomes of previously isolated Old World...
