A quantitative comparison is given of aggressive play and aggression in terms of the duration and type of movement patterns employed, and the relationships between individuals. The mean length of contact in play was greater than in aggression, whereas chases tended to be longer in adult male aggression than in play, Linear hierarchies describing the overall(More)
The hydroxyproline-rich glycoproteins (HRGPs) are the major structural proteins of the extracellular matrix of algae and land plants. They are characterized by a rigid polyproline type II (PPII) conformation and extensive O-glycosylation of 4(R)-hydroxy-l-proline (Hyp) residues, which is a unique post-translational modification of proteins. The functional(More)
To assess sociodemographic differences in beliefs about the health effects of cigarette smoking and passive smoke exposure, we recently surveyed 2092 adults in St. Louis and Kansas City, Mo. The percentages of respondents who knew that smoking causes lung cancer, emphysema, and heart disease were 76.7, 74.1, and 67.2, respectively. After multivariate(More)
Glycosylation is a common post-translational modification of proteins implicated in cellular recognition processes and controlling protein conformation.1 Typically, carbohydrates are O-linked to serine (Ser) and threonine (Thr) or N-linked to asparagine (Asn). Glycosylation of (2S,4R)-4-hydroxyproline (Hyp) is widespread in the plant kingdom and occurs in(More)
OBJECTIVES This study evaluated a community organization approach that emphasized involvement of audiences in program planning and implementation in promoting nonsmoking among African American residents of low-income neighborhoods. METHODS The quasi-experimental design involved a 24-month intervention in 3 low-income, predominantly African American(More)
The conformations of peptides and proteins are often influenced by glycans O-linked to serine (Ser) or threonine (Thr). (2S,4R)-4-Hydroxyproline (Hyp), together with L-proline (Pro), are interesting targets for O-glycosylation because they have a unique influence on peptide and protein conformation. In previous work we found that glycosylation of Hyp does(More)
We describe the synthesis of a fused bicyclic C-glucosylproline hybrid (GlcProH) from commercially available 2,3,4,6-tetra-O-benzyl-d-glucopyranose. The GlcProH was incorporated into the model peptides Ac-GlcProH-NHMe and Ac-Gly-GlcProH-NHMe. Postsynthetic modifications can be introduced via derivatization of the carbohydrate scaffold. Conformational(More)
