She goes so far as to suggest that the extraordinary plumpness of newborn humans, much fatter than other infant primates, is an attempt to convince their parents that they are worth rearing.
Certain psychological experiments, such as those in which infant primates are separated from their mothers and exposed to frightening stimuli in an effort to understand problems teenagers have when they enter high school, would also come into question.
Additionally, an upcoming collaborative study conducted by the University of Pittsburgh - School of Medicine, the University of Kentucky and Thoughtful House Center for Children in Austin, Texas reveals evidence of substantial functional brain damage in infant primates who received the birth dose of Hepatitis B Vaccine.
Thus, the vaccine-dosing schedule was adjusted to accommodate this projected 4 1 developmental trajectory of infant primates.
Two-choice color discrimination tests have been used to evaluate basic learning skills in infant primates for many years (Harlow 1959).
Based on the observed toxicokinetics in infant primates receiving low-dose IM thimerosal injections (Burbacher et al. 2005), toxicity following TCV administration would appear unlikely.
Because infant development in primates shares many parallels with that of humans, a wide range of neurobehavioral tests, adapted from assessments used with human infants, are routinely implemented for monitoring developmental trajectories in infant primates following exposure to environmental neurotoxicants (Burbacher and Grant 2000; Gunderson et al. 1988; Rice 1999; Rice and Hayward 1997).
In the present study we examined neurobehavioral effects of TCVs using both an accelerated vaccine primate schedule and the recommended pediatric schedule, neither of which appeared to affect neurobehavioral outcomes, thus suggesting that the toxicokinetics of EtHg in infant primates is not a limiting factor when using an accelerated schedule of dosing.
These data suggest that, like man, the infant nonhuman primate is much more susceptible to lead intoxication than is the adult.
We initiated the present study in order to directly compare the blood and brain levels of Hg in infant nonhuman primates exposed orally to MeHg or via intramuscular (im) injections of vaccines containing thimerosal.
Studies of infant nonhuman primates exposed to O3 for cyclical periods over 6 months demonstrated altered airway architecture with fewer and narrower small airways, disordered smooth muscle orientation, and hyperplastic bronchiolar epithelium (Fanucchi et al. 2006).
