Caregiver-infant and toddler interactions during diapering: Caregiver responsiveness and child well-being and involvement.

The findings of this empirical research provide new information about the importance of caregiver interactions during care routines, specifically diaper changing, in supporting infant and toddler involvement and well-being. This correlational study involved observations of 144 separate diapering cycles by 31 caregivers with 74 infants and toddlers in 30 infant and toddler classrooms in a U.S.

Peer effects on low-income children's learning and development.

Using data from a large study of 78 high-quality Head Start classrooms in 12 sites across the U.S., this study examined whether peers' receptive vocabulary skills and teacher-reported social-emotional (S-E) functioning (i.

Assessment of food, nutrition, and physical activity practices in Oklahoma child-care centers.

The purpose of the current study was to determine the obesogenic practices in all-day child-care centers caring for preschool-aged children. This study used a cross-sectional, self-reported survey mailed to centers across Oklahoma (n=314). Frequency of responses and χ(2) were calculated comparing region and star rating.

Exenatide improves hypertension in a rat model of the metabolic syndrome.

Background: Exenatide is a peptide incretin mimetic that has glucoregulatory actions associated with weight reduction. Previous reports demonstrated acute increases in blood pressure after systemic or intracerebroventricular administration of exenatide or glucagon like peptide 1 (GLP 1) in rats. However, there are limited studies testing the chronic effects of these peptides on arterial pressure and no reports showing the effects of these peptides to reverse hypertension in the context of the metabolic syndrome.

Pharmacological actions of the peptide hormone amylin in the long-term regulation of food intake, food preference, and body weight.

The ability of amylin to reduce acute food intake in rodents is well established. Longer-term administration in rats (up to 24 days) shows a concomitant reduction in body weight, suggesting energy intake plays a significant role in mediating amylin-induced weight loss. The current set of experiments further explores the long-term effects of amylin (4-11 wk) on food preference, energy expenditure, and body weight and composition.
