Proteomic Analysis of a Noninvasive Human Model of Acute Inflammation and Its Resolution: The Twenty-one Day Gingivitis Model
The 21-day experimental gingivitis model, an established noninvasive model of inflammation in response to increasing bacterial accumulation in humans, is designed to enable the study of both theExpand

Developmental changes in c-fos expression to an age-specific social stressor in infant rats
Young rats become immobile when exposed to a potentially infanticidal adult male rat. Male-induced immobility declines during the preweaning period, paralleling the decrease in infanticidal threat.Expand

Effects of para-chlorophenylalanine and 5-hydroxytryptophan on mouse killing behavior in killer rats
The effects of para-chlorophenylalanine (PCPA) on mouse killing behavior were examined in natural killer rats. Forty-eight hr after injection, this serotonin synthesis inhibitor, at relatively lowExpand

Renal Effects and Metabolism of Isoflurane in Man
The intra- and postanesthetic renal effects and metabolism of isoflurane were studied in nine surgical patients; six control patients received halothane. Isoflurane was metabolized to a slightExpand

Effect of paraventricular injection of neuropeptide Y on milk and water intake of preweanling rats
This study investigated the effect of paraventricular nucleus (PVN) injection of neuropeptide Y (NPY) on milk and water intake of 2- and 15-day-old sated rats. On the day prior to testing, rat pupsExpand

The biological processes that mediate and modulate the perception of pain in the infant animal are not well studied and thus nociception during early development is poorly understood. In the adultExpand

The Role of the Medial Prefrontal Cortex in Innate Fear Regulation in Infants, Juveniles, and Adolescents
In adult animals, the medial prefrontal cortex (mPFC) plays a significant role in regulating emotions and projects to the amygdala and periaqueductal gray (PAG) to modulate emotional responses.Expand
