WW domains are protein modules that bind proline-rich ligands. WW domain-ligand complexes are of importance as they have been implicated in several human diseases such as muscular dystrophy, cancer, hypertension, Alzheimer's, and Huntington's diseases. We report the results of a protein array aimed at mapping all the human WW domain protein-protein interactions. Our biochemical approach integrates parallel synthesis of peptides, protein expression, and high-throughput screening methodology combined with tools of bioinformatics. The results suggest that the majority of the bioinformatically predicted WW peptide ligands and most WW domains are functional, and that only about 10% of the measured domain-ligand interactions are positive. The analysis of the WW domain protein arrays also underscores the importance of the amino acid residues surrounding the WW ligand core motifs for specific binding to WW domains. In addition, the methodology presented here allows for the rapid elucidation of WW domain-ligand interactions with multiple applications including prediction of exact WW ligand binding sites, which can be applied to the mapping of other protein signaling domain families. Such information can be applied to the generation of protein interaction networks and identification of potential drug targets. To our knowledge, this report describes the first protein-protein interaction map of a domain in the human proteome.

"Infant-demand" care and conventional Western care, as practiced by London parents, are associated with different benefits and costs. As used by proximal care and Copenhagen parents, infant demand parenting is associated with less overall crying per 24 hours. However, the proximal form of infant-demand parenting is associated with more frequent night waking and crying at 12 weeks of age. Copenhagen infants cry as little per 24 hours as proximal care infants but are settled at night like London infants at 12 weeks of age. Colicky crying bouts at 5 weeks of age are unaffected by care. The findings have implications for public health care policy. First, they add to evidence that bouts of unsoothable crying, which are common in early infancy, are not much affected by variations in parenting, providing reassurance that this aspect of infant crying is not parents' fault. Second, the findings provide information that professionals can give to parents to help them to make choices about infant care. Third, the findings support some experts' concerns that many English parents are adopting methods of care that lead to increased crying in their infants. There is a need for informed debate among professionals, policy makers, and parents about the social and cultural bases for the marked differences between London and Copenhagen parents' approach to care.

Human papillomavirus (HPV) vaccination rates do not meet the Healthy People 2020 objective of 80% coverage among adolescent females. We describe the development and initial feedback about an HPV vaccine comic book for young adolescents. The comic book is one component of a multi-level intervention to improve HPV vaccination rates among adolescents. Parents suggested and provided input into the development of a HPV vaccine comic book. Following the development of the comic book, we conducted a pilot study to obtain initial feedback about the comic book among parents (n=20) and their adolescents ages 9 to 14 (n=17) recruited from a community-based organization. Parents completed a pre-post test including items addressing HPV knowledge, HPV vaccine attitudes, and about the content of the comic book. Adolescents completed a brief interview after reading the comic book. After reading the comic book, HPV knowledge improved (2.7 to 4.6 correct answers on a 0–5 scale; p<0.01) and more positive attitudes toward HPV vaccination (p<0.05) were reported among parents. Parents confirmed that the comic book’s content was acceptable and adolescents liked the story, found it easy to read, and thought the comic book was a good way to learn about being healthy. Parents provided valuable information in the development of a theoretically-based comic book and the comic book appears to be an acceptable format for providing HPV vaccine information to adolescents. Future research will include the comic book in an intervention study to improve HPV vaccination rates.

Objective: To conduct a comprehensive process evaluation of a policy, systems, and environmental (PSE) change intervention. Design: Quasi-experimental, mixed methods. Setting: Low-income urban school district. Participants: Fifth-grade students in 4 schools assigned to 2 intervention and 2 comparison schools (intervention, n = 142; comparison, n = 170). Intervention: Both groups received a nutrition curriculum delivered by classroom teachers. Intervention schools also received 10 PSE lessons taught by paraprofessional educators. Main Outcome Measures: Quantitative data were obtained from fidelity and observation checklists, grading rubrics and self-reported student surveys. Focus group and interviews provided qualitative data. Quantitative measures included assessments of PSE and fruit and vegetable knowledge, as well as assessment of times fruits and vegetables (FV) were consumed yesterday. Analyses: Qualitative data were analyzed using inductive content analysis. Quantitative data were analyzed using repeated measures analysis of variance and analysis of co-variance. Results: Fidelity, dose, reach, and acceptance of PSE intervention were high; students felt more empowered, although PSE lessons were considered lengthy and complicated. Intervention PSE and FV knowledge scores were significantly higher than comparison scores (F 37.56 , P < .001; and F 3.94 , P < .05, respectively). However, issues in communication were identified between school staff and researchers. Conclusions and Implications: Policy, systems, and environmental classroom interventions commented on the differences between quantitative and qualitative assessments, and this suggests the need for more sensitive quantitative assessments. Future research should look at long-term outcomes as this study only looked at short-term outcomes.
